MODULE 3:
INSTALL COMPUTER SYSTEM
AND NETWORKS
What is computer?
 An electronic device that accepts, processes, store,
and outputs data at high speeds according to
programmed instructions
 Somebody who calculates numbers or amounts using
machine
Types of Computers
 Analog Computers – an analog computer can
perform several mathematical operations
simultaneously. It uses continuous variables for
mathematical operations and utilizes mechanical or
electrical energy.
 Digital Computers – are suitable for complex
computation and have higher processing speeds.
They are programmable. Digital computers are
either general purpose computers or special purpose
ones.
 Hybrid Computers – These computers are
combination of both digital and analog computers
Classification of Computers
 Mainframe Computers – is for highly critical
applications such as bulk data processing and ERP.
It has the capacity to have multiple operating
systems.
 Minicomputers – In terms of size and processing
capacity, minicomputers lie in between mainframes
and microcomputers.
 Servers – They are computers designed to provide
services to client machines in a network. It has large
capacities and powerful processors.
Classification of Computers
 Supercomputers – Highly calculation-intensive
task can be effectively performed by means of
supercomputers. Quantum physics, weather
forecasting, molecular theory are best studied by
using this computers.
 Microcomputers – It has microprocessor. It
doesn’t occupy space as much as mainframes. Also
called a personal computers.
Types of Personal computers
 Desktops – it is intended to be used on a single
location. The spare parts are low costs and widely
available in the market.
 Laptops – similar in operation to desktops, laptop is
handy for mobile use. Laptops run on a single battery
which can be charged with the use of adapters.
 Netbooks – It is smaller compare to laptops and has
lesser specifications compare to laptops
 Personal Digital Assistants (PDAs) – a handheld
commonly known as palm top.
 Tablet Computers – are mobile computers that
are very handy to use. It uses the touch screen
technology.
 Wearable Computers – can be worn on the body
and are often used in the study of behavior modeling
of human health.
