Introduction
Computer are significant elements of present world. In this present report fundamentals of
computer system are studied including different environments such as home, education, business
where computers are highly used. Main purpose of using computers in any organization is to
attain efficiency, accuracy and reducing user’s workload. In this report studies are done about
role and function that computer system performs in various organization. Computer is composed
of various components which can be broadly classified as Hardware, software and peripheral
devices which will be discussed in the current report. The report will provide a comparison
between different type of computers that are for serving different purpose at different fields.
Design is provided in the report together with system specification for all the user in the network.
Configuration and installation of Computer system is illustrated below with various images.
Lastly, this report will discuss about routine maintenance task that is to be done along with
system upgrading for performance enhancement.

LO1
1.1 explain the role of computer systems in different environments
Personal Computer Systems are typically used for routine work because of their various
advantages, such as accurate data handling, consistent work, and higher performance ability.
They help in storing, managing, compiling and processing different kinds of data, with a higher
level of efficiency. They enhance human accuracy for various tasks, and also provide various
platforms for different environments as under:
Hospitals: Systematic records are kept for the patients availing the hospital facility, and can be
typically accessed at the front desk itself. They also help with different surgical operations, by
giving a visual presentation of the patient’s condition, such as EGC Operation (Anderson and
Jay, 2012). Most of the hospitals’ managerial tasks can also be done on the systems, thus
increasing efficiency

Education: These systems also help students and teachers both, by maintaining efficient records,
and offering the potential of technological learning to the students by means of visual aids.
Students can search for any desired information in Internet Search Engines from their library
computer systems, and gain the requisite information. The systems also assist the students with
their projects.

Transport: Computer systems enhance the functioning of transport systems, by assisting in
booking tickets, reservations, and keeping passenger records. For instance, the Oyster Card in the
UK is used to give tickets to passengers on credit, which can be utilized to avail any means of
transportation to their needed location.

Gaming: Gamers are increasingly using computer systems due to the greater amount of
graphical and visual effects provided by these systems, which make the user feel as if he/she is in
a virtual arena with realistic looking objects and scenarios.

Hotels: Customer data, worker data as well as other stakeholder data can be recorded in the
computer systems, and this facility is being increasingly used by hotels. Hotel managers also
utilize these systems to input the requisite data, and record it, so that the complex manual
procedures involved in clerical tasks can be avoided. Using these systems, decisions can be made
quickly, and client behaviour can also be routinely assessed.

1.2 explain the hardware, software and peripheral components of a computer system
Components of a computer system is broadly classified as hardware and software.
Hardware Components
Computer Hardware is the physical components or machineries that makes a computer system.
The common hardware is the memory, Central processing unit, storage device and Network
Interface Card.
Central processing Unit is the heart of the computer. CPU performs all the vital operations of the
computer including all the arithmetic and logical calculations. It is responsible for receiving
input data, executes commands given, and then processes the information by communicating
with all the Input and Output devices (Wolf, 2012).

Storage devices are used for storing various information in the computer. Hard disk is used for
permanently or temporarily data storage which cab be recovered as necessity. In computer
system, Memory is also referred as RAM or Random-Access Memory, which holds data for
supporting the processor to perform various function.

Network interface cards or NIC is an electronic circuit which is responsible for connecting the
computing devices to its Internet services provider to access internet.

Software Components
Software are basically logical program that are used for monitoring, controlling and executing
various computer function. Software can be categorized into three types including
 Operating system
 Application software
 Utility software.
Operating system: it is referred to a low-level software, it is responsible for managing all the
hardware and other software resources present in the computer system. The entire computer
system depends on the operating system for it running. OS forms an interface between the
computer hardware and user. Elementary responsibilities of OS are memory management, file
management, process management, and controlling peripheral devices and handling input and
output devices. IOS and Windows are two common OS (Lajoie and Derry, 2013).).

Application programs: these are software that are designed for performing of synchronized tasks
or operation. It takes help of the operating system services for the benefit of the computer user.
For an instance, database programs, games.
