UNDERSTANDING COMPUTER
A computer is one of the most brilliant inventions of mankind. Thanks to the
computer technology, we were able to achieve storage and processing of huge amounts
of data; we could rest our brains by employing computer memory capacities for storing
information. Due to computers, we have been able to speed up daily work, carry out
critical transactions and achieve accuracy and precision in work. Computers of the
earlier years were of the size of a large room and were required to consume huge
amounts of electric power. However, with the advancing technology, computers have
shrunk to the size of a small watch. Depending on the processing power and size of
computers, they have been classified under various types. Let us look at the
classification of computers.
Different Types of Computers Based on the operational principle of computers, they
are categorized as analog, digital and hybrid computers.
Analog Computers: These are almost extinct today. These are different from a digital
computer because an analog computer can perform several mathematical operations
simultaneously. It uses continuous variables for mathematical operations and utilizes
mechanical or electrical energy.
Digital Computers: They use digital circuits and are designed to operate on two
states, namely bits 0 and 1. They are analogous to states ON and OFF. Data on these
computers is represented as a series of 0s and 1s. 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.
Special purpose computers, as their name suggests, are designed for specific types of
data processing while general purpose computers are meant for general use.
Hybrid Computers: These computers are a combination of both digital and
analog computers. In this type of computers, the digital segments perform process
control by conversion of analog signals to digital ones. Classification of Computers
The following are the classification of the different types of computers based on their
sizes and functionalities:
Mainframe Computers: Large organizations use mainframes for highly critical
applications such as bulk data processing and ERP. Most of the mainframe computers
have the capacities to host multiple operating systems and operate as a number of
virtual machines and can substitute for several small servers.
Minicomputers: In terms of size and processing capacity, minicomputers lie in
between mainframes and microcomputers. Minicomputers are also called mid-range
systems or workstations. The term began to be popularly used in the 1960s to refer to
relatively smaller third generation computers.
Servers: They are computers designed to provide services to client machines in
a computer network. They have larger storage capacities and powerful processors.
Running on them are programs that serve client requests and allocate resources like
memory and time to client machines. Usually they are very large in size, as they have
large processors and many hard drives. They are designed to be fail-safe and resistant
to crash.
Supercomputers: The highly calculation-intensive tasks can be effectively
performed by means of supercomputers. Quantum physics, mechanics, weather
forecasting, molecular theory are best studied by means of supercomputers. Their
ability of parallel processing and their well-designed memory hierarchy give the
supercomputers, large transaction processing powers.
Microcomputers: A computer with a microprocessor and its central processing
unit it is known as a microcomputer. They do not occupy space as much as
mainframes do. When supplemented with a keyboard and a mouse, microcomputers
can be called personal computers. A monitor, a keyboard and other similar input
output devices, computer memory in the form of RAM and a power supply unit come
packaged in a microcomputer. These computers can fit on desks or tables and prove
to be the best choice for single-user tasks.
Personal computers come in different forms such as desktops, laptops and
personal digital assistants (refer to Figure 3). Let us look at each of these types of
computers.
Desktops: A desktop is intended to be used on a single location. The spare parts
of a desktop computer are readily available at relatively lower costs. Power
consumption is not as critical as that in laptops. Desktops are widely popular for daily
use in the workplace and households.
Laptops: Similar in operation to desktops, laptop computers are miniaturized
and optimized for mobile use. Laptops run on a single battery or an external adapter
that charges the computer batteries.
Netbooks: They fall in the category of laptops, but are inexpensive and relatively
smaller in size. They had a smaller feature set and lesser capacities in comparison to
regular laptops, at the time they came into the market.
Personal Digital Assistants (PDAs): It is a handheld computer and popularly
known as a palmtop. It has a touch screen and a memory card for storage of data.
PDAs can also be used as portable audio players, web browsers and smart phones.
Most of them can access the Internet by means of Bluetooth or Wi-Fi communication.
Tablet Computers: Tablets are mobile computers that are very handy to use.
They use the touch screen technology. Tablets come with an onscreen keyboard or use
a stylus or a digital pen. Apple's iPod redefined the class of tablet computers. Wearable
Computers: A record-setting step in the evolution of computers was the creation of
wearable computers. These computers can be worn on the body and are often used in
the study of behavior modeling and human health. Military and health professionals
have incorporated wearable computers into their daily routine, as a part of such
studies. When the users' hands and sensory organs are engaged in other activities,
wearable computers are of great help in tracking human actions. Wearable computers
do not have to be turned on and off and remain in operation without user intervention.
Elements of a Computer System
Hardware
Software
Peopleware
1. Hardware refers to the physical, tangible computer equipment and devices which provides
support for major functions such as input, process, output and storage.
2. Software – this term refers to the collection of electronic instructions that tells the computer what
to do. It is a computer program that is installed in your computer.
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.
