What is It
Computers in a Changing World
Many scientific and technological advances mark the beginning of the
twentieth century. These advances include inventions such as airplane,
television, and most especially the computer. Computers are changing our
lives, they are sweeping away the old ways of doing things with their superb
speed and reliability.
As many of today’s basic functions are being simplified by technology,
computers have been on the forefront in developing innovations through its
many functions.
In this digital world, having the knowledge and skills in computer
servicing is the start and most fundamental of all.

I. Computer and Its Types
A computer is an electronic machine that processes and stores
information. It takes in raw information using input devices, stores in the
memory until it is ready to be processed in the processing unit and sends out
results using output devices.
www.google.com
6
Computers are classified into four (4) different types based on its
processing power and size:
THE TYPES OF COMPUTERS
1. Supercomputer is the fastest and most powerful computer in terms of
performance and data processing. It uses its power to run one program at
a time.
Used in:

Research and exploration

Weather forecasting

Nuclear weapon testing
www.google.com
2. Mainframe computer is not as powerful as the supercomputer. It is
designed to run multiple programs concurrently. It is commonly used in:

Banks

Educational Institution

Insurance companies
www.google.com
3. Minicomputer, also known as “Midrange” computer fill the space between
the mainframe and microcomputer. It is smaller than Supercomputer or
Mainframe computer but bigger and more powerful than the microcomputer.
They are generally used as mid-range servers.
Some of its uses are as:

Data Management device

Communications Portal

Process Control

4. Microcomputer is the most widely used computer – desktop, laptops,
tablets, and smartphones. It is the cheapest among the different classes of
computers. This computer is design for general usage such as
entertainment, education and work purposes.

System
Application
Software
Utility
Programs
Kinds of Computer Software
A. System Software coordinates the activities and functions of hardware and
software. It controls the operations of computer hardware and provides an
environment or platform for all the other types of software to work in. It is the
most basic type of software in any computer system, which is essential for
other programs, applications and the whole computer system to function.

they are usually operated by the user to maintain a smooth running of the
computer system.
14
B. Application Software is a computer program that performs a specific task.
(Application software examples – MS Office, OpenOffice, Media Players,
MS Access, educational software, media development software, Antivirus
software, etc.)
www.google.com
3. Peopleware – the most important element of a
computer system is its users. The following types of people interact with a
computer system:
a. System Analysts - are people who design the operation and processing
of the system
b. System Programmers – are people who write codes and programs to
implement the working of the system.
c. System Operators – are people who operate the system and use it for
different purposes. Also called the end users like students, teachers, and
other professionals.
III. HOW THE COMPUTER WORKS?
Data are raw facts about things, events, or activities that are captured,
recorded, and stored on the computer. These can be in the form of words,
numbers, or pictures.
Data become information when these have been arranged or
organized to be of use and to have meaning to the user.
INPUT – in this step, data are entered into the computer through input
devices, such as keyboard and mouse.
PROCESS – is the computer’s method of analyzing, managing, or
manipulating data. The data entered into the computer undergo
changes. The Central Processing Unit (CPU) directs the operation
of the input and output devices to create the needed information.
OUTPUT – You get the output once the computer is finished processing the
data. It could be displayed on the monitor, printed on paper, or
heard through speakers.
15
STORAGE – The processed data are kept for future use. We use Hard Disk
Drive to store the information.
