Introduction
The increasing demand for the computers in the present world tells us the importance of
computers in almost every sectors especially in the IT companies. So systems need to
be maintained and upgraded for smooth and linear workflow. So there is an
organization SYNERGY, in which director wants the system to be upgraded by the
company. Before proceeding there, a detailed information of computer are given and
their roles and sectors are also defined. As well as comparison is also made between
various computers types.
Apart from this, system design will get introduced to the proper solution in second
section. Also, specification of the system and some case of testing is given in section
third. In the last phase of this assignment, the performance enhancement of the system
is given just by introducing routine maintenance and regular updates in the hardware as
well as the software.

LO1 Understand the function of computer systems
1.1 Explain the role of computer systems in different environments
Computer System:
The combined package of the software as well as the hardware components completely
make up the computer system. The system is consisting of various functional
specifications as well as non-functional specifications configured within the system. It is
an electronic device for the users which can perform lots of tasks and can store very
large amount of data with very high speed and high accuracy. It can perform actions like
an input can be taken, processing of data, storage of useful information, and give a fast
response as an output.
The expanding interest and prevalence made the system very useful for almost every
person in this world. Almost each and every sector is making use of computers at
present time due to its high performance and multitasking nature in a fraction of time.
So in different sector, the role of the computer has been discussed.

Computer System role in many different Environment:
 Gaming: In the sector of gaming, the system can be used to display the virtual
environment in front of users. Any type of game can be played on the system and
with required configurations.

 Education: In the sector of education, the requirement of the system is at prior.
As the computers stores very high amount of data and process it in milliseconds
and the manipulation of the data can be done at very high speed. It helps in this
sector by enhancing the learning skills of the students with the improvisation in
the skills of teaching also. Also, online material for studies provided which can be
accessed using internet (Uniassignment, 2017).

 Hospital: In the sector of the hospital, systems can be used for keeping all the
track record activities taking place in a hospital on daily bases like patients data,
staff members, doctors record, and the visitors. Other than this it helps in various
machine also like ECG and many more.
