INTRODUCTION
Information technology is defined as the connections and use of various computers in
order to store, extract, modify, transfer and delete data for personal as well as for the business
operations. It consists networking systems through the usage of internet by which firms can
access the huge information and people to expand it's business (Bannon, Bardzell and Bødker,
2018). Organization chosen here is TESCO, it is one of the leading international supermarket
retail company based in UK. It mainly deals with the products and services like clothing, home

business, role of IT in management and stages of SDLC.
LITERATURE REVIEW
Task 1
Computing terminologies
CPU
Central processing unit is considered as a brain of the computer. Because it directs the
computer systems to perform the tasks and it follows the instructions as directed by CPU. User
commands the computer systems to perform actions and accordingly they pursue those activities
and display results on the monitor screen.
RAM
Random access memory is read and write memory where user can modify and stores it's
data. It is known as the volatile memory which means that the it only stores the data as long as
the supply of power is being processed, and again if user starts the systems it's automatically
extracts the data which was save earlier before shutting down the computer last time (Jakkaew
and Hemrungrote, 2017).
ROM
Read only memory is a memory where user can only read the data or instructions that are
given in a computer systems. It is known as the non-volatile memory because if power supplies
