For 1st year college

1. Importance of Computer Literacy
Computer Literacy is the knowledge and understanding
computer concepts, limitations and ability to use
computers and technology efficiently. Computer Literacy
can also refer to the comfort level someone has with using
computer programs and other applications that are
associated with computers.

2. What is Computer?
 Computer is a electronic device
capable of interpreting and executing
programmed commands for
input, output, computation and logic
operations.
Advantages of Computer
1.Speed
2.Repettiveness
3.Accuracy
4.Stores and Retrieve Information
5.Logic Operations
6.Self-Operating

3.  Speed- A computer can process data
faster than other machine. Designed to
perform similar task.
 Repetitiveness- A computer can easily
perform same operations millions of
times in exactly the same way method.
 Accuracy- A computer is accompanied by
light accuracy result
 Stores and Retrieve information- A
computer is like a human brain because it
can store data, acts instructions and
retrieve information.

4.  Logic Operations- A computer can
perform operations based on alternative
courses of Action.
 Self- Operating- Once data and
Instructions are into the computer
memory, the computer is capable of
executing the instructions without human
intervention.

5. Disadvantages of Computer
 1. It cannot correct wrong instructions
 2.Prone to machine Defection
 3. It cannot interpret object
ELEMENTS OF COMPUTING PROCESS
1. Hardware
2. Software
3. Data
4. People
5. Procedures
6. Connectivity

6.  Hardware- This are the physical devices that
comprised a computer system. Example are
monitor, keyboard and printer.
 Software- a set of instructions called
programs, Example are Ms Word and Ms
Excel.
 Data- are inputs for processing, Example are
name, address, and Tel.No.
 People- provide the inputs and the use. The
computer output also called users/end-
users.
 Procedures-The steps to be followed to
accomplish a specific tasks.
 Connectivity-An electronic connections and
communication between computer system.

7. Computer Uses
 Computers are just as common as pen and
paper for writing, especially among youth.
For many applications - especially
communicating- computers are preferred
over pen, paper, and typewriters because of
their ability to duplicate and retain
information and ease of editing.
 As personal computers become common
place and they become more powerful , the
concept of computer literacy is moving
beyond basic functionality to more powerful
applications under the heading of literacy.

8.  Of course, arguments about computers being
common - place in the first world has equal
access to the latest forms of technology.
however, there is a pronounced digital divide
that separates both physical access to
technology and the ability to use that
technology effectively. Where computers are
widespread, they are also a part of education.
Computers are used in schools for many
applications such as writing papers or
searching the Internet information. Computer
skills are also a subject being specifically
taught in many schools, especially from
adolescence onward - when the ability to
make abstractions forms.

9. Uses of Computer
 Information System/Data Processing
 Personal Computing
 Science Research and Engineering
 Education and References
 Computer-Aided Design
 Artificial Intelligence
 Process/Device Control
 Entertainment
 Communication

10. Importance of Computer Literacy
The precise definition of "computer literacy" can
very from group to group. Generally, literate (in
the realm of books) connotes one who can read
any arbitrary book in their native language
[s], looking up new words as they are exposed to
them. Likewise, an experienced computer
professional may consider the ability to self - tech
(i.e. to learn arbitrary new programs or tasks as
they are encountered) to be central to computer
literacy. In common discourse, however,"
computer literacy" often connotes little more
than the ability to use several very specific
applications (usually Microsoft word, Microsoft
Internet Explorer, and Microsoft Outlook) for
certain very

11. well - defined simple tasks, largely by rote. (This is
analogous to a child claiming that they "can read"
they have rote - memorized several
small children's books. Real problems can arise
when such a "Computer Literate" person
encounters a new program for the first
time, and large degrees of "hand holding " will
likely be required.) Being "literate" and "functional"
are generally taken to mean the same thing.
 The pervasiveness of computers continues to
grow at an outstanding rate. Computers always
change; they become smaller, faster and more
powerful. These changes have motivated the
modern society to become comfortable with basic
computer - related skills.

12.  The level of computer literacy one must
achieve to gain an advantage over others
depends both on the society one is in and
one's place in the social hierarchy. Prior to
the development of the first computers in
the b1950s, the word computer referred to a
person who could count, calculate, compute.
The fear of some educators today is that
computer training in schools will serve only
to train data-entry clerks of the next
generation, low level workers of the so
called knowledge industries. On the other
hand, some hope that enhanced computer
literacy will

13.  enable a new generation of cultural
producers to make meanings and circulate
those in the public sphere. The wildfire of
cultural production associated with sites
such as Youtube seems to support this
notion.
 Different countries have different needs
for computer literate people due to their
society standards and level of technology
. The world's digital divide is now an
uneven one with knowledge nodes such
as India disrupting old North/South
dichotomies of knowledge and power.

14.  Computer Literacy is considered to be a
very important skill to possess while in
the first world. Employers want
their workers to have basic computer
skills because their company becomes
ever more dependent on computers.
Many companies try to use computers to
help run their company faster and
cheaper.

15. Computer Competency
 Having some skill in a computer so that you
can use it to meet your information needs
and improve your productivity.
 The user feel comfortable using and
operating a computer
 Understand the impact of Computers on
society , now and in the future
 Be an intelligent consumer of computer and
other computer equipments collectively
called hardware.
 Be an intelligent consumer of computer
related products and services.

16. Categories of Computer
 Personal Computer/Microcomputer
 Workstation
 Midsize mainframe
 Mainframe
 Super Computer

17.  Personal Computer- A small computer
designed for use by an individual.
 Workstation- a high performance single-user
computer with sophisticated input/output
devices that can be easily networked with
other workstation computer.
 Midsize mainframe- a midlevel computer built
to perform complex computation while
dealing efficiently with a high level input/output
from users via terminal.
 Mainframe- a high level computer designed for
the most intensive computational tasks.
 Supercomputer- A large extremely fast and
expensive computer used for complex or
sophisticated calculation.
