Information technologies provide enormous
potential for enhancing productivity in
various organizational processes including
management.
The objective of this lesson is to demonstrate
how IT can enhance productivity of
Management functions.
5

In this lesson we are giving you an
understanding to the IT world, different
components of it, and how IT can be applied
to improve your efficiency and productivity in
Management functions as professionals.
6

In the modern world of today, the
applications of the ICT are almost as limitless.
New and better technologies are being
introduced everyday for easier and greater
uses.
7

We are living in an industrialized society in
which the efficiency and the effectiveness
plays very important role. The above two
factors depend on various kinds of
automation. ICT are very special in that
because it gives us many methods of
processing automation.
8

Computers, Telecommunication
Equipments and other technologies
associated with automation come under the
general heading of “Information
Technology”. It has changed the way of
organizations are operated and impacts on
individuals, organizations and overall society.
9

A computer is a Machine. It is an electronic
device that executes the instructions in a
program.
10

Basically computers has four functions

accepts data
processes data
produces data
stores results



Input
Processing
Output
Storage
11

As we know a system is a group of integrated
parts that have the common purpose of
achieving some objective.






When you consider a computer as a system it
is made up of the following elements
Hardware
Software
Live ware - User
Firmware - Data
12





Computer Hardware is comprised with all the
physical, tangible or machinery parts of the
computer. For the simplicity we can
categorize computer Hardware into four
categories.
Input
Processing
Storage
Output
13

Identify and discuss about the various types
of hardware components available in an ICT
system.
14

A computer cannot do anything without
instructions. Set of instructions is called a
program. Programs and data are used to
control the hardware of the computer
system. Programs and data are called
software. Whatever you want your computer
to do, you give your instructions using
software.

15

Different software are available to
accomplish various tasks using a computer.
Basically there are two types of software.

 System Software
 Application Software
16

Identify different software available and
discuss about the usage of each
17

Computers are categorized from the largest
& most powerful to the smallest and least
Powerful. The Personal or the micro
computer is the type of the computer that
you can see in common.
18

Identify different types of computers and
identify their different applications.
19


By definition a computer is a very efficient data
processing unit. Input to the computer is
normally referred as data and after processing
the output is information. Information is one of
the crucial components of the organizational
decisions making process.
Different information is essential in making
sensible and accurate decisions in different
managerial levels in an organization.
20

Therefore dissemination or transferring of
data from one computer to another
computer in right format, right time is really
essential rather than processing and storing it
inside a standalone computer. How can we
achieve this? The answer is computer
networks.
21

Computer Network is a set of computers
and other peripheral components
interconnected to share resources.

Therefore the main purpose of the Computer
Network is to share resources among the
computers and to communicate among
computers.
22


In a computer network you can identify
different components. The computer that
provides the services to the other computers
is known as a Server and the computers
receiving the services are known as Clients
Computer networks come in many different
types, shapes and sizes.
23

List down different types of computer
networks available and the components of
them. Discuss the purpose of each
component.
24

Depending on the geographical area in which
the network is spread, they can be classified
as follows.

LAN (Local Area Networks) - A LAN connects
network devices over a relatively short
distance. A networked office building, school,
or home
25

MAN (Metropolitan Area Network) – This
connects an area larger than a LAN but
smaller than a WAN, such as a city, with
dedicated or high-performance hardware.

WAN (Wide Area Networks) - As the term
implies, a wide-area network spans a large
physical distance. A WAN like the Internet
spans most of the world!
26

Dial-Up Networks – With this a computer
can be connected to a network in a remote
area through telephone when necessary.
27

Identify the different physical existence of
computer networks (network topologies)

Identify advantages and disadvantages of
those network topologies
28

Internet is a super highway of information

Internet is a Network of Computer Networks,
which integrates computers from personal
notebook Computers and PDAs to huge
complex Computing Systems.
29


Since Internet Provides so many different
service and facilities it is difficult to give a
complete definition. The simplest way to
describe the Internet is with one word
“Communication”.
The original purpose of the Internet was to
enable people in different locations to share
text-only documents. Now there is much
more you can do using the Internet.
30

You can send and receive email messages; you can
search the world for particular files or for files that
contain particular words; you can have a live
conversation using typed text or voice or even
video; you can read electronic magazines and
newspapers; you can check on the weather forecast
or the score of a ball game; you can play computer
games with several people at once; you can post
messages to newsgroups on a common topic; you
can buy books, CDs, software, wine, or just about
anything.
31

Internet has taken the world to concepts of
globalization, global village, global family, Ecommerce and so on…
32

List the important uses of internet. Suppose
you need to take internet facility to your
computer, what are the different methods
available to achieve it?
33


Search-Engine: Programs on the Internet
that help users to search for files and
information. Examples are Google, Infoseek,
Yahoo.
Intranet: An intranet is a private network
that is contained within an enterprise. It may
consist of many interlinked local area
networks and also use leased lines in the wide
area network.
34

Wi-Fi Hot Spot: A hotspot is a site that offers
Internet access over a wireless local area
network through the use of a router
connected to a link to an Internet service
provider. Hotspots typically use Wi-Fi
technology for the wireless network.
