INFORMATION COMMUNICATION & TECHNOLOGY

Information & Communication Technology
Computer: A computer is a truly amazing machine that performs a specified sequence of operations as per the set
of instructions (known as programs) given on a set of data (input) to generate desired information (output ).
A complete computer system consists of fourparts:
✓ Hardware: Hardware represents the
physical and tangible components of the
computer.
✓ Software: Software is a set of electronic
instructions consisting of complex codes
(Programs) that make the computer perform
tasks.
✓ User: The computer operators are known asusers.
✓ Data: Consists of raw facts, which the
computer stores and reads in the form of
numbers.
Functionalities of a computer
Any digital computer carries out five functions in gross terms:
✓ Takes data as input.
✓ Stores the data/instructions in its memory and use them when required.
✓ Processes the data and converts it into useful information.
✓ Generates the output
✓ Controls all the above four steps.
The following features characterize this electronicmachine:
✓Speed ✓ Flexibility
✓Accuracy ✓ Low cost
✓Storage and Retrieval
✓Reliability
✓ Repeated ProcessingCapabilities
Applications of Computer
Following list are various applications of computers in today's arena.
✓ Business ✓ Health Care
✓ Banking ✓ Engineering Design
✓ Insurance ✓ Military
✓ Education ✓ Communication
✓ Marketing ✓ Government
Following are the main five generations ofcomputers:
S. No. Generation & Description
1 First Generation (1946-1959) - Vacuum tubebased
2 Second Generation (1959-1965) - Transistorbased
3 Third Generation (1965-1971) - Integrated Circuitbased
4 Fourth Generation (1971-1980) - VLSI microprocessorbased
5 Fifth Generation (1980-onwards) - ULSI microprocessorbased
Computer hardware consists of the followingcomponents:
1. CPU (Central Processing Unit): CPU is considered as the brain of the computer. It performs all types of
data processing operations, stores data, intermediate results and instructions (program).It controls the
operation of all parts of computer.
Components [A] CPU itself has following three components:
✓ ALU (Arithmetic Logic Unit): When the control unit encounters an instruction that involves
mathematical calculation or decision/logic, it passes the control to the second component, i.e., the
arithmetic logic unit (ALU). The ALU includes a group of registers - memory locations built directly
into the CPU - that are used to hold data that are being processed by the current instruction.
✓ Registers: The register is the smallest high-speed storage area in the CPU. All data must be
represented in a register before it can be processed.
✓ Control Unit: This unit controls the operations of all parts of computer but does not carry out any
actual data processing operations
[B] Primary memory consists of mainly two types ofmemories:
1. Random Access Memory (RAM): RAM is the internal memory of the CPU for storing data,
program and program result. It is read/write memory which stores data until the machine is
working. As soon as the machine is switched off, data is erased.
RAM is volatile, i.e. data stored in it is lost when we switch off the computer or if there is a power
failure. Hence a backup uninterruptible power system (UPS) is often used with computers. RAM is small,
both in terms of its physical size and in the amount of data it can hold.
There are mainly three types of RAMavailable:
I. Dynamic Random Access Memory (DRAM): A type of physical memory used in most personal
computers. The term dynamic indicates that the memory must be constantly refreshed2 (reenergized) or
it loses its contents. This type of memory is more economical.
II. Static Random Access Memory (SRAM): A type of memory that is faster and less volatile than
DRAM, but requires more power and is more expensive. The term static is derived from the fact that
it does not need to be refreshed like DRAM.
III. Synchronous Dynamic Random Access Memory (SDRAM): A type of DRAM that can run at much
higher clock speeds.
2. Read Only Memory (ROM): The memory from which we can only read but can not write on it . This
type of memory is non-volatile. The information is stored permanently in such memories during
manufacture. A ROM, stores such instructions that are required to start a computer. This operation is
referred to as bootstrap.
There are mainly three types of ROMavailable:
a. MROM (Masked ROM): The very first ROMs were hard-wired devices that contained a pre-
programmed set of data or instructions. These kinds of ROMs are known as masked ROMs which are
inexpensive.
b. EPROM (Erasable and Programmable Read Only Memory): The EPROM can be erased by exposing
it to ultra-violet light for a duration of up to 40 minutes. Usually, an EPROM eraser achieves this
function.
c. EEPROM (Electrically Erasable and Programmable Read Only Memory): The EEPROM is
programmed and erased electrically. It can be erased and reprogrammed about ten thousand times.
Both erasing and programming take about 4 to 10 ms (milli second).
Memory
A memory is just like a human brain. It is used to store data and instructions. Computer memory is the storage
space in computer where data is to be processed and instructions required for processing are stored. The
memory is divided into large number of small parts called cells. Each location or cell has a unique address which
varies from zero to memory size minus one.
Memory is primarily of three types
✓ Cache Memory: It is a very high speed semiconductor memory which can speed up CPU. It acts as a buffer
between the CPU and main memory.
✓ Primary Memory/Main Memory: Primary memory holds only those data and instructions on which
computer is currently working. It has limited capacity and data is lost when power is switched off.
✓ Secondary Memory: This type of memory is also known as external memory or non-volatile. It is slower
than main memory. These are used for storing data/Informationpermanently.
1. Secondary Storage (External Storage Devices) : Floppy diskettes, hard disk, tapes and optical disks come
under the category of external storage devices or ancillary storage devices. These devices are very sensitive to
environmental conditions (humidity and temperature) as well as to external magnetic fields and need to be
stored carefully.
a. Floppy Disk : Floppy disks are primarily used on PCs. Information on a floppy disk is recorded in the
magnetized states of particles of iron oxides evenly placed upon concentric circles known as tracks.
b. Hard Disk: It is a non-removable enclosed magnetic disk included in most PCs. It contains a stack of metal
platters, each coated with iron oxide, that spin on a spindle and the entire unit is encased in a sealed
chamber.
c. Magnetic Tape: This is plastic tape, usually made of Mylar that is coated with iron oxide, thereby enabling
the introduction (writing); retention (memory) and reading of magnetically recorded information. The best
use of tape storage is for data that you do not use very often.
2. Peripherals: Peripheral devices are devices connected to the computer externally. If a peripheral device is
disconnected, the computer will still be able to work; only functions performed by this peripheral device
will not be available.
Mainly there are following types of peripheraldevices:
A. Input Devices (How to tell it what to do): This unit makes link between user and computer. The
input devices translate the information into the form understandable by computer.
a. Keyboard- The most common and very popular input device which helps in inputting data to the
computer
b. Mouse- Mouse is the most popular pointing device and cursor-control device having a small palm size
box with a round ball at its basewhich senses the movement of mouse and sends corresponding signals
to CPU when the mouse buttons are pressed.
c. Joy Stick- To move cursor position on a monitor screen. It is mainly used in Computer Aided Designing
(CAD) and playing computergames.
d. Light pen- It is used to select a displayed menu item or draw pictures on the monitor screen.
e. Track Ball- Mostly used in notebook or laptop computer, instead of a mouse .This is a ball which is half
inserted and by moving fingers on ball, pointer can be moved
f. Scanner- A scanner allows you to scan printed material and convert it into a file format that may be
used within the PC.
g. Digitizer- It converts analog information into digital form.
h. Microphone-Microphone is an input device to input sound that is then stored in digital form.
i. Magnetic Ink Card Reader (MICR)-MICR input device is generally used in banks because of a large
number of check to be processed every day.
j. Optical Character Reader (OCR)- OCR scans text optically character by character, converts them
into a machine readable code and stores the text on the system memory.
k. Bar Code Reader- A device used for reading bar coded data (data in form of light and dark lines).
Bar coded data is generally used in labeling goods, numbering the books.
l. Optical Mark Reader(OMR)- A special type of optical scanner used to recognize the type of mark
made by pen or pencil.
B. Output Devices: (How it shows you what it is doing) Output devices translate the computer's output into
the form understandable by users.
Monitors: Monitors, commonly called as Visual Display Unit (VDU), are the main output device of a computer.
It forms images from tiny dots, called pixels that are arranged in a rectangular form. The sharpness of the
image depends upon the number of pixels.
There are two kinds of viewing screen used formonitors.
a. Cathode-Ray Tube (CRT): The CRT display is made up of small picture elements called pixels.
The smaller the pixels, the better the image clarity, or resolution
b. Flat- Panel Display: The flat-panel display refers to a class of video devices that have reduced
volume, weight and power requirement in comparison to the CRT.
Printer: Printer is an output device, which is used to print information on paper.
c. Impact Printers: The impact printers print the characters by striking them on the ribbon which is
then pressed on the paper.
d. Non-Impact Printers: Non-impact printers print the characters without using ribbon. These
printers print a complete page at a time so they are also called as Page Printers. Laser
Printers, Inkjet Printers
Note:
✓ Data: Data can be defined as a representation of facts, concepts or instructions in a formalized manner
which should be suitable for communication, interpretation, or processing by human or electronic machine.
✓ Information:- Information is organized or classified data which has some meaningful values for the
receiver. Information is the processed data on which decisions and actions arebased.
✓ Data Processing Cycle: Data processing is the re-structuring or re-ordering of data by people or machine to
increase their usefulness and add values for particular purpose. Data processing consists of basic steps input,
processing and output.
These three steps constitute the data processingcycle.
✓ Input -Input data is prepared in some convenient form for processing. The form will depend on the
processing machine. For example, when electronic computers are used, the input data could be recorded
on any one of several types of input medium, such as magnetic disks, tapes and soon.
✓ Processing - In this step input data is changed to produce data in a more useful form. For example,
paychecks may be calculated from the time cards, or a summary of sales for the month may be calculated
from the sales orders.
✓ Output - The result of the proceeding processing step are collected. The particular form of the output data
depends on the use of the data. For example, output data may be pay-checks foremployees.
Language Processors:
Assembler: This language processor converts the program written in assembly language into machine language.
Interpreter: This language processor converts a HLL(High Level Language) program into machine
language by converting and executing it line byline.
Compiler:-It also converts the HLL program into machine language but the conversion manner is different.
It converts the entire HLL program in one go, and reports all the errors of the program along with the line
numbers.

Software
Software: software represents the set of programs that govern the operation of a computer system and make the
hardware run. There are two types of software
➢ System Software: The system software is collection of programs designed to operate, control, and extend
the processing capabilities of the computer itself. System software are generally prepared by computer
manufactures. System software serves as the interface between hardware and the end users. Examples:
Operating System, Compilers, Interpreter, Assembler etc.
➢ Application Software: It is the set of programs necessary to carry out operations for a specified application.
Application software can subdivide into threecategories:
(A) Packages:-
Packages

and free space on your computer.
Antivirus Software It scans yours disk for viruses and removes them if
any virus is found.
C. Customized Software: This type of software is tailor-made software according to a user’s requirement.
Number System
When we type some letters or words, the computer translates them in numbers as computers can understand
only numbers. A computer can understand positional number system where there are only a few symbols called
digits and these symbols represent different values depending on the position they occupy in thenumber.
A value of each digit in a number can be determinedusing
✓ The digit
✓ The position of the digit in the number
✓ The base of the number system (where base is defined as the total number of digits available in the
number system).
1. Decimal Number System: The number system that we use in our day-to-day life is the decimal number
system. Decimal number system has base 10 as it uses 10 digits from 0 to 9. In decimal number system,
the successive positions to the left of the decimal point represent units, tens, hundreds, thousands and
soon.
2. Binary Number System: Uses two digits, 0 and 1, also called base 2 number system . Each position
in a binary number represents a 0 power of the base (2). Last position in a binary number
represents a x power of the base (2).
3. Octal Number System: Uses eight digits, 0,1,2,3,4,5,6,7, also called base 8 number system, Each
position in an octal number represents a 0 power of the base(8).
4. Hexadecimal Number System: Uses 10 digits and 6 letters, 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. Letters
represents numbers starting from 10. A = 10. B = 11, C = 12, D = 13, E = 14, F = 15. Also called base 16
number system .Each position in a hexadecimal number represents a 0 power of the base(16).
Number Conversion
There are many methods or techniques which can be used to convert numbers from one base to another.
We'll demonstrate here the following
✓ Decimal to Binary System
✓ Binary to Decimal
Decimal to Binary System
Steps
Step 1 - Divide the decimal number to be converted by the value of the newbase.
Step 2 - Get the remainder from Step 1 as the rightmost digit (least significant digit) of new base number.
Step 3 - Divide the quotient of the previous divide by the newbase.
Step 4 - Record the remainder from Step 3 as the next digit (to the left) of the new base number.
Repeat Steps 3 and 4, getting remainders from right to left, until the quotient becomes zero in Step 3. The last
remainder thus obtained will be the most significant digit (MSD) of the new base number.
Example
Decimal Number: (29)10
Calculating Binary Equivalent:
Step Operation Result Remainder
Step 1 29 / 2 14 1
Step 2 14 / 2 7 0
Step 3 7 / 2 3 1
Step 4 3 / 2 1 1
Step 5 1 / 2 0 1
As mentioned in Steps 2 and 4, the remainders have to be arranged in the reverse order so that the first
remainder becomes the least significant digit (LSD) and the last remainder becomes the most significant digit
(MSD).
Decimal Number: (29)10 = Binary Number: (11101)2.
Binary toDecimal System
Steps
Step 1 - Determine the column (positional) value of each digit (this depends on the position of the digit and the
base of the number system).
Step 2 - Multiply the obtained column values (in Step 1) by the digits in the corresponding columns.
Step 3 - Sum the products calculated in Step 2. The total is the equivalent value in decimal.
Example
Binary Number: (11101)2
Calculating Decimal Equivalent:
Step Binary Number Decimal Number
Step 1 (11101)2
((1 x 24) + (1 x 23) + (1 x 22) + (0 x 21) + (1 x 2
0))10
Step 2 (11101)2 (16 + 8 + 4 + 0 + 1)10
Step 3 (11101)2 (29)10
Binary Number: (11101)2 = Decimal Number: (29)10
Networking
Network: Computer Networks means interconnected set of autonomous system that permit distributed
processing to information.
✓ Sender Computer
✓ Sender equipment
(Modem)
Five components:
✓ Receiver Equipment(Modem)
✓ Receiver Computer
✓ Communication Channel ( TelephoneCables)
Classified on the basis of GeographicalCoverage:
connectivity within a campus or small
➢ Local Area Network (LAN): A local area
network is relatively smaller and privately
owned network with the maximum span of 10
km.
➢ Metropolitan Area Network (MAN) : MAN is
defined for less than 50 Km and provides
regional
geographical area.
➢ Wide Area Network (WAN): A wide
Area Network (WAN) is a group
Communication Technology ,provides
no limit ofdistance.
Types of Network
1. Point to Point Network: When a packet is sent from one router to another intermediate routers, the
entire packet is stored at each intermediate router, stored there till the output line is free and then
forwarded. A subnet using this principle is called point to point or packet switchednetwork.
Topologies for a point to point Subnet
➢ Star: Each device has a dedicated point to point link only to a central controller, usually called a hub.
➢ Tree: A tree topology is a variation of a star.
➢ Ring: Each device has a dedicated point to point line configuration only with the two devices on either side
of it.
➢ Bus: One long cable acts as a backbone to link all the devices in the network.
2. Broadcast Networks: Broadcast networks have a single communication channel that is shared by all the
machines on the network.
Transmission Media
➢ Network Cables: Network cables are
used to connect computers. The most
commonly used cable is Category 5 cable
RJ-45.
➢ Distributors: A computer can be connected
to another one via a serial port but if we need
to connect many computers to produce a
network, this serial connection will not work.
The solution is to use a central body to which
other computers, printers, scanners etc. can
be connected and then this body will manage
or distribute network traffic
➢ Repeaters: A repeater is an electronic
device that receives a signal and retransmits
it at a higher level or higher power, or onto
the other side of an obstruction, so that the
signal can cover longer distances.
➢ Bridge: A bridge is a product that connects a
local area network (LAN) to another local area
network that uses the same protocol (for
example, Ethernet or token ring).
➢ Routers: A router is a device that forwards data
packets along networks. A router is connected to at
least two networks, commonly two LANs or WANs
➢ Internal Network Cards: Network
card is a necessary component of a
computer without which a computer
cannot be connected over a network.
It is also known as network adapter
or Network Interface Card (NIC).
Most branded computers have
network card pre-installed. Network
cards are of two types: Internal and
External Network Cards.
➢ External Network Cards: External
network cards come in two flavours
like Wireless and USB based. Wireless
network card need to be inserted into
the motherboard but no network cable
is required to connect to network.
➢ Universal Serial Bus (USB): USB card
are easy to use and connect via USB
port. Computers automatically detect
USB card and can install the drivers
required to support the USB network
card automatically.
➢ Modem (Modulator –DE Modulator):
Modem is a device attached to computers that
can convert digital signals to analog signals to
analog signals and vice versa.
Operating System
An Operating system is a program, which acts as an interface between a user and the hardware.
Characteristics of Operating System:
✓ Memory Management -- keeps tracks of
primary memory i.e. what part of it is in
use by whom,what part is not in use etc.
and allocates the memory when a process
or program requests it.
✓ Processor Management -- allocates
the processor(CPU) to a process and
de-allocates processor when it is no
longer required.
✓ Device Management -- keeps track of all
devices. This is also called I/O controller
that decideswhich process gets the device,
when, and for how much time.
✓ File Management -- allocates and de-
allocates the resources and decides who
gets theresources.
✓ Security -- prevents unauthorized
access to programs and data by means
of passwordsand similar other
techniques.
✓ Job accounting -- keeps track of time and
resources used by various jobs and/orusers.
✓ Control over system performance --
records delays between request for a
service and fromthe system.
✓ Interaction with the operators -- The
interaction may take place via the console
of the computer in the form of instructions.
Operating System acknowledges the same,
does the corresponding action and informs
the operation by a display screen.
✓ Error-detecting aids -- Production of
dumps, traces, error messages and other
debuggingand error-detectingmethods.
✓ Coordination between other software and
users -
- Coordination and assignment of compilers,
interpreters, assemblers and other software to
the various users of the computer systems.

E - Commerce (Electronic Commerce) : E-Commerce is the buying and selling of goods and ser- vices on the
internet.The visitor tothe site cansellorbuyanyproductor serviceonline.Thetransac- tions are enable through
credit cards, Debit cardsetc.
E-Business (Electronic Business) : E-Business is the administration of conducting business via the Internet.
This would include the buying and selling of goods and services, along with providing technical or customer
support through the Internet. E-Business is used in conjunction with E-Com- merce, but includes services in
addition to the sale of goods.
E-Administration:The use of ICTs (Information and Communication technologies) to modernize the state, the
creation of data repositories for MIS (ManagementInformation Systems), computerisation of records.
E-Services: the emphasis here is to bring the state closer to the citizens. Examples include provi- sionofonline
services.E-Services andE-Administrationtogether constitutewhatis generally termed e-governance.
E-Governance: The use of IT to improve the ability of government to address the needs of society. It includes
the publishing of policy and programme related information to transact with citizens. It extends beyond
provision of on-line services and use of IT for strategic planning and reaching devel- opment goals of the
government.
E-Democracy: The use of IT to facilitate the ability of all sections of society to participate in the governance of
the state. The remit is much broader here with a stated emphasis on transparency', accountability and

Types of E-Commerce:
1. Business to Customer (B2C): The basic concept of this model is to sell the product online to the
customers. It provides direct selling through online. B2C is the indirect trade between the company
and consumers. Directly interact with the customers is the main difference with other business
model.
2. Business toBusiness (B2B):Itis similar to manufacturer issuing goods to the retailer orwhole- saler.
This model defines that Buyer and seller are two different entities. It consists of longest form of E-
Commerce. It is one of the cost effective way to sell out product through out the world.
3. Customer to Customer (C2C): It helps the online dealing of goods or services among people. though
there is no major parties needed but the parties will not fulfill the transactions without the program
which is supplied by the online market dealer such as eBay.
4. Peer to Peer (P2P): It is a discipline that deal itself, which assists people to instantly shares related
computer files and computer sources without having to interact with central webserver.
5. M-Commerce: This model deals with conducting the transactions with the help of mobile. The mobile
consumers can interact each other and can lead the business. M-Commerce (Mobile Com- merce)

COMPUTER S E C U R I T Y
Security: Security controls access to data in files and permits only authorized use of terminals and other
equipment. Control is usually through various levels of passwords assigned on the basis of need toknow.
Typical approaches to improving Computer security can include the following :
• Physically limit access to computers to only those who will not compromise security.
• Hardware Mechanisms that impose rules on computer programs, thus avoiding depending on computer
programs for computer security.
• Operating system Mechanisms that impose rules on programs to avoid trusting Computer Programs.
• Programming strategies to make computer programs dependable and resist subversion.
Security Tools:
Firewall:Afirewallisa setof relatedprograms,locatedat anetworkgatewayserver,thatprotects the resourcesof a
privatenetworkfromusersofothernetworks. Firewall caneitherbehardwaredevices or software programs.
They provide protection from Online intrusions. A firewall is designed to pre- vent unauthorized Internet
users from accessing your computer. All messages entering your Computer from the Internet pass through the
firewall which examines each message. The firewall blocks any message that was not specifically requested by
yoursystem.
Encryption: It can be used to protect the message from unauthorized users. It can be done in several ways by
switching the characters around, replacing characterswith others, and even removing characters from the
message.
Cryptographic Techniques: It can be used to defend data in transit between systems reducing the probability that
data exchanged between systems can be intercepted or modified. Secure crypto processors can be used to
leverage physical security techniques into detecting the security of the system. Strong authentication
techniques can be used to ensure that communication end-points are who they say they are.
Intrusion-Detection- System: It can be scan a network for people that are on thenetwork butwho should not be
there or redoing things that they should not be doing. For example trying a lot of pass- words to gain access to
the network.
Pinging: The Ping application can be used by potential crackers to find if an IP address is reachable. If a cracker finds
a computer they can try a port scan to detect and attack services on that computer.
Anti-Virus Software : Anti-virus software consists of computer programs that attempt to identify, thwart and
eliminate computer viruses and other malicious software (Malware). The term "Antivirus" is used because it is
designed exclusively to combat computerviruses.
Antivirus software typically uses two different approaches to accomplish this:
☛ Examining (Scanning) files to look for known viruses matching definitions in a virus dictionary.
☛ Identifying suspicious behaviour from any computer program which might indicate infections.
VIRUS (Vital Information Resource Under Siege): The full form is "Vital Information Resource Under Siege". A
computer virus is a computer program that spreads by inserting copies of itself into other executable code or
documents. Virus program that runs on your computer without your knowledge and can cause damage to your
files.Acommon way to receive a virus is through an attachment viae-mail.
Worm: Worm is a self-replicating program. It replicates itself to new computers using the flaws and then begins
scanning and replicating again. The difference between a virus and worm is that a worm does not create copies
of itself on one system. It propagates through computer networks.
Trojan Horse : It is a program in which malicious or harmful code is contained inside apparently harmless
programming or data in such a way that it can get control and do its chosen form of dam- age.TrojanHorses
cannot replicate automatically.ATrojanhorse canbeused to setup a back door in a computer system so that the
intruder can return later and gainaccess.
Malware (Malicious Software) : Itis a software designed specifically to damage or disrupt a system such as a virus
or Trojan horse.
Spyware: Spyware is a software that performs actions such as advertising, collecting personal data, or changing the
configuration of your computer, usually without obtaining your consent. Spyware that displays advertisements
and tracks your personal information is known as "Adware".
Spam: E-mail spam also known as "Junk e-mail" or "Unsolicited Bulk e-mail (UBE), is a subset of spam that
involves nearly identical messages sent to numerous recipients by e-mail.
Phishing: Phishing is a fraudulent activity of acquiring the sensitive information by the use of a fake identity during
electroniccommunication.
Spoofing: It occurs when the sender of an e-mail message pretends to be someone else, they falsely manipulate
the "From" field in an e-mail. This is usually done to make you release sensitive information
Key loggers : Key logger is a software program designed to record (log) every keystroke on the machine on which
it runs. Key logger is also known as "Key Stroke logger" or "System Monitor".
Packet Sniffer: A packet sniffer is an application that captures TCP/IP data packets, which can maliciously be used
to capture passwords and other data while it is in transit either within the computer or over the network.
Root Kit: Aroot kit is a computer program that enable administrator - level access to a computer or computer
network. A cracker installs a root kit on a computer after first obtaining user-level access, eitherbyexploitinga
knownvulnerabilityorcrackingapassword.Oncetherootkitisinstalled,itallows the hacker to mask intrusion
and gain root or privileged access to the computer.
Cyber crime: It contains all criminal offences which are committed with the aid of communication devices in a
network.
example are:
• Unauthorized access, malicious code, and denial-of-service attacks.
• Theft of service and certain financial frauds.
• Spamming and copyright crimes, particularly those facilitated through peer-to-peer networks.
• Hacking, phishing, identify theft, child pornography, online gambling securities fraud.
Hacking:Hacking is the activity of programmatically gaining access to a computer application thatis otherwise in
accessible.The act of gaining anunauthorised access to a computer is knownas "Hacking".
Hacker: AHacker is someone involved in computer security specializing in the discovery of exploits in systems orin
obtaining or preventing unauthorized access to systems through skills, tactics and detailedknowledge.
