What are Advantages of a Computer System
Computer is a programmed
device with a group of instructions to perform specific tasks
and generate results at a really high speed. A
Computer is a machine that can solve
difficult and different problems, process data, and
store & retrieve data.
Perform calculations faster and accurately as compared from
humans. The literal meaning of computer may be a device which will calculate.
However, modern computers can do tons quite calculate.
Computer can be defined as a machine which receives input stores it and then
process the stored data as per the instructions given by the user of the
computer and finally gives the output as required.
Derived from Dictionary word means “to calculate”.
- An Electronic Machine
- Takes data as Input
- Stores data
- Process data
- Generates Information as Output
- Computer is an machine
that’s designed to figure with Information.
- The term computer springs
from the Latin term ‘computare’, this suggests to calculate or programmable machine.
- Computer cannot do
anything without a Program.
- The Word ‘Computer’ means
to the middle Processor Unit plus Internal memory.
Computer is a tool for enhancing human capability. It can perform
intellectual (for example, decision-making) as well as physical tasks (cheque
sorting). It is highly versatile and its use is limited by human imagination.

Advantages of a Computer
Computers have their effects on society, organizations and
individuals. The impacts in terms of advantages are discussed below.
Benefits to Individuals
Professionals like doctors, engineers, teachers, legal practitioners
and accountants are benefited in many ways. Specialized applications for these
professionals help increase their efficiency. For example, a doctor can be at
his home and treat his patient online, perform surgery through the help of robots
at a distant hospital etc. A teacher can help thousands of students use his
materials and lecture classes through computer networks. An engineer can
develop designs for buildings easily and quickly. Legal practitioners use
computers for preparing their briefs. They are also immensely helped by the
database of court verdicts in preparing their briefs. Consumers get better and
quicker service at service counters like at railway stations (booking on any
train from any of the booking counters, cancelling tickets from any booking counter
etc.) and bank counters or through Internet banking etc. Digital library,
interactive online classrooms, multimedia presentations, online examinations
etc. have revolutionized learning process for students. Farmers can plan crops
based on cropping pattern in other regions and countries so that the crop they
produce fetches better prices. Fishermen use computer-based information on
weather and fish movement for increasing their catch.
Get a better understanding of data
Organizations that use computer are benefited in a number of
ways. It is used in every area of business starting from data entry to
strategic decision-making.
Computers also help users to understand data better. For
instance, there could be a database of sold items in a business. A businessman
can identify what products are sold best quantity time of year and what items
are not selling with the help of stored data on the computer. To get this type
of information about the business can provide a better understanding of their
customers, and can increase business growth by eliminating issues in
production.
Computer is extensively used in business organizations in the
following areas.
- Computers in
decision-making
- Computers in planning and
forecasting
- Computers in financial and
inventory control
- Process automation
- Computers in market
research
- Computers in communication
- Computers in e-commerce
Keeps You Connected
Internet-based communication has revolutionized communication
in the recent years. Email, instant messaging, bulletin boards, Voice over IP
etc. are the popular Internet-based tools which are used for communication
globally.
Computers help you to connect with your friend, family, or
other relatives with long-distance through e-mail and social networking. Also,
you can connect with more than thousands of people via online mediums VoIP and
chat services, such as Line, Skype. The connectivity between you and people all
around the world is also a better way to meet long-distance people over the
network. Although you cannot meet physically with people over the Internet, you
can still share your ideas, feelings, and make touch with them.
Benefits to Improve our Technology
Technology impacts on the social sphere in many ways. It has
both positive and negative consequences. Technological pursuits have the
objective of raising quality of human life. But they often interfere with the
nature and create imbalances.
More effective use of technology. Computer is used in every
technological pursuit. It also improves efficiency of use of technology.
Better and cheaper communication
Computer is central to any communication technology these
days. Telecommunication uses computer extensively for switching, billing, call
forwarding, caller identification services etc.
Increase
your productivity
Computers help increase
user productivity, and users become more productive at everything you do
on the software running on the computer with a good understanding. For
instance, when you have work on an Excel worksheet
with a basic understanding, you can create, edit, delete, store, calculation, and
print documents and letters. With all pre-existing technologies, all of these
things were either impossible or much slower.
Huge storage and fast retrieval
Computer
has huge storage capability. For a personal computer, 128 MB RAM is almost a
standard toady. The main memory can be upgraded further by inserting RAM chips
that are available in modules of 64 MB, 128 MB and so on. Cache memory is also
available in Pc. Cache memory is faster access memory device and hence it
improves processor performance.
One of the most
useful advantages of computers is able to store and access vast amounts of
data, which can be retrieved in the future. For example, a computer system and
devices like eBook readers have enough storage capacity as they can store
hundreds or thousands of books. Also, you can store movies, pictures, songs
digitally, and documents on the computer, and can quickly find data accordingly
and share information between devices. It reduces plastics and paper
requirements that are used to make non-digital versions of the media.
You can
earn money
You can make
money by the computer in many different ways when it is connected to the
Internet. For instance, you can create and run an online store as it is much
cheaper as compared to have a physical store. Also, when you create a once
online store, you can sell your product to anyone in the world as your product
would a large network of audiences on the Internet. Additionally, you can also earn
money on the computer with a spreadsheet, which is a perfect tool to breakdown
your spending and keep track of your finances.
Automate
and Programmable
Computer can be
programmed to function automatically and this differentiates it from any other
calculation device. It functions as programmed for any stretch of time until
the condition to terminate is satisfied.

Reduction in Paper Work and Cost
The use of computers for data processing in an organization
leads to reduction in paper work and results in speeding up a process. As data
in electronic files can be retrieved as and when required, the problem of maintenance
of large number of paper files gets reduced. Though the initial investment for
installing a computer is high but it substantially reduces the cost of each of
its transaction.
Networking capability
Computers can be interconnected into a network. Network in turn can be
connected to other networks. Networks extend the capability of computers. The
networks provide the basic infrastructure for electronic communications, electronic
commerce, online trading and information services.
Free from fatigue
Computer is free from fatigue. It does not get tired of work
and never loses concentration. It can perform basic arithmetic operations with
the same degree of speed and accuracy for any extent of time continuously, with
the same amount of efficiency as the first transaction.
Save Time and Multitasking
Today, there
are many services that the computer can complete with very few times and can
save your time. Though
computers are basically designed to carry out only arithmetic operations, yet
they are capable of performing almost any task that has a series of finite
logical steps. Computers can be used for communications, process control,
research, weather forecasting, healthcare, online trading, education, training,
defence applications and so on.
