INTRODUCTION
Information technology is having a great influence on all business organizations which
can make work easier such as manufacturing, education, health etc. In the present era, computer
system and internet are being used everywhere which can support all operational activities such
as communication, automation, information sharing and so on (Brack and et. al., 2011).
Computer system is helping in all business activities which can increase output, performance and
efficiency. There are several components of a computer system like desktop, monitor, hard disk,
etc. Presently, 1 TB and 2 TB hard disk are attached in personal computers which give a large
storage space for users. A person can choose a computer system on the basis of their uses. The
present report is focused on SYNERGY which is a recruitment business entity. It operates their
business activities in United Kingdom which is the need of computer system to increase work
performance and efficiency. Mr Timothy Kelly is the director of this organization and wants to
integrate all departments through information technology (Britto and et. al., 2010). Systematic
design specification helps to develop systems which is in need. By this, organization can achieve
their objectives and increase their work efficiency.
TASK 1
1.1Explaining the role of computer systems in different environments
In today’s scenario, computer has become an integral part and a basic need for a human
being. Computer system is a multipurpose device which can be programmed to solve various
complex problems such as arithmetic and logical calculations. In the modern workplace,
computer systems have become an important tool for keeping database, store system, save
records and making analysis of these records and data base (Cahill and Zuckerberg, 2014). It can
save money and time both and make works easier for an individual. There are various roles of a
computer system in different environments which are given as below:
Home: Computer system at home commonly fulfills the general purpose such as keeping
personal and family records, surfing on internet, professional activities, playing games, watching
movies and so on. Apart from that, now a days, it is also used for social media networking such
as Facebook, YouTube, Instagram, etc.
Business: Computer system plays a significant role in each and every business. There are
various tasks such as maintaining records, data management, employee’s information,

documentation and so on. These systems can be used from small and medium sized businesses to
large scale organizations (Deng and et. al., 2012). In multinational companies, such systems are
used for sharing information through integrated networking system. Example: Primark
supermarket is a retail chain which is having large number of stores and warehouses across the
world. In order to maintain register and records for their products, computer system can help
them to do their work smoothly. Example; Primark super market is a retail chain which having
large number of stores and warehouses across the world. In order to maintain register and records
for their products computer system can help them to doing their work smoothly.
Educational institutions: Today, all schools, colleges and universities are using
computers in order to provide better teaching and learning to their students. There are various
fields which require computer system to make their study easy (Ellis, 2012).
Medical and Hospitals: Places like hospitals also need computer system which can help
to keep records of their patients and their staff. Apart from that, there are various medical
facilities which require such system to provide medical treatment to its patients.
Banks: There are various information and millions of date in banks which are more complex and
competitive to store for a long time. Computer system provided facilities to keep financial
information for a long time. It can also provide an integrated network to financial institution to
communicate with their various branches and share information with them.
Defense: Computer system is also used by various security organizations for their
military use. For example, keep safe country's IT and critical infrastructure form cyber threat.
Computer system provides 360 degree surveillance to various government authorities to protect
various institution from enemy country (Ferreira, 2011).
1.2 Explaining the hardware and application Software and peripheral components of a computer
system.
Hardware: It is a physical component of a computer system which consists of various
elements such as CPU, monitor, key board and hard disk, etc.
CPU: his is known as central processing unit which is one of the significant parts of a computer
system. In this system, every program directly goes to CPU in a binary language and convert in
to the output according to human language.
