INTRODUCTION
The invention of computer is considered to be a revolutionary invention for mankind and
their progressive use can be seen in almost all the industrial sectors and at all the levels of the
economy. The computers are mainly known for their speed and accuracy which may not be
guaranteed by the human mind or body. The stress and fatigue that the human body feels
because of the work is not seen in the computers and they have a capacity to work 24X7.
In the given report we have focused on the importance of computers and their accuracy and
reliability which is discussed in terms their use for real time operations in the industry and
networking and real time operations. We also consider various parts of the computers that are
like software, hardware and other peripheral components which are build-up on the basis of
such computer designs. Here we have also considered the sizes and scope of computers in the
current markets and their scope in the future. We have tried o examine the changes in costs
for these computers as well. Various increasing specifications for 2D and 3D printing features
of the computers have also been discussed herein.
At the end we have tried to conclude with some suggestions and showing the impact of the
computers which is continuously increasing in the market. The future technologies that will
be connected with the computers are also analyzed in the report.

TASK 1
1.1 Role of computer systems in different environment
The computers in the present-day systems are designed and produced according to the needs
of the organization (Card, 2017). The increasing dependency is also increasing the
unemployment in various sectors because of the increased accuracy and speed of the
computers.
Home:
People generally use computers in order to chat with their relatives and friends and connect
with the world. The management of expenses along with the backup of information and
personal data is effectively managed with computers at home (Ricci et.al. 2015).
Business:
The performance and speed along with the accuracy is one of the most basic features of
computers which can be useful for the business purpose. With the use of efficient computer
systems and technology the cost on labor resources can be reduced further.

Gamming:

For the purpose of gaming special computers and laptops are designed which not only
provide an enhance gaming experience but also support the graphic cards which help the
gamers to have a professional exposure (Kavanagh and Johnson, 2017).

Networking and communication:
In order to keep in touch with the day to day requirements of the world and keep connected
with the requirements of the world, which also provides better information and data
(Silberschatz et.al. 2014). The sharing and receiving of information also becomes easier with
the advent of computers.
Real-time operations:
Various serious operational enhancements is also being facilitated by the advent of new
technological advances. The computer systems also consider and help in the controlling of
various operations like launching of rockets and controlling the temperature deviations and
also to detect various hurdles in the path is there are any detected (Wyglinski et.al. 2016).
This also enhances the planning process which also determines the risks and uncertainties in
the organization.
The computers today are designed in such a manner in which they are able to forecast future
assumptions as well on the basis of the study of past data and current positions.

1.2 explain the hardware, software and peripheral components of a computer system
Main components
Central processing unit (CPU):
The main part or as it is rightly known, the brain of the computer is the part of the computer
hardware without which no computer can function properly (Nalluri et.al. 2017).
Memory:
The primary and secondary memory of the computer functions very efficiently in functioning
and storage. The Random-access memory (RAM) holds the basic intermediate data of the
computer system whereas the secondary memory can help store the larger volumes of data
(Clemm et.al. 2016).
Bus size:
In order to achieve the highest standards of performance and progress in the market,
the firm definitely needs better technology which can be achieved by using the 64 bit
architecture through which the transfer can be superfast.
Hardware requirements
Network interface card:
In order to get a faster connectivity in the firm as well as the services that are to be provided
the customers. The Ethernet cables and wireless adapters make it easier (Hau, 2015).
