Versatility: Computers can perform  a wide range  of tasks, from calculations and word
                     processing to complex simulations and gaming.

                      Automation: Computers can perform tasks  automatically without continuous human
                     intervention once programmed.
                      Diligence: Unlike humans, computers don’t  get  tired  and  can  perform  repetitive  tasks
                     consistently without losing focus or quality.
                  Uses of a Computer

                  Computers are powerful devices that help us with many tasks in our daily lives. Here are some of
                  the key ways they make life easier:
                      Learning:  Computers  support  online  classes,  research,  and  understanding  topics  better
                     through educational videos and resources.

                      Communication: They allow us to stay connected with friends and family through email,
                     messaging, and video calls.
                      Entertainment: Computers provide access to games, movies, music, and other activities for
                     fun and relaxation.
                      Homework and Studies: Students use computers to write reports, make presentations, and
                     complete assignments efficiently.
                      Creative Work: Computers are great for creating art, editing videos, producing music, and
                     designing graphics.

                      Information Access: They give quick and easy access to knowledge on almost any topic via
                     the Internet.
                      Workplace Efficiency: Computers help with tasks like managing data, creating reports, and
                     improving communication in the workplace.
                      Coding and Programming: They are essential  for learning programming,  building
                     applications, and developing software.
                  Basic Operations of a Computer

                  A computer performs four key operations:

                       Input (Raw Data): This is the unprocessed information entered into the computer using
                     input devices like keyboards, mouse, or scanners.
                       Process:  In this step,  the  computer  converts raw  data  into  meaningful information  by
                     organising, analysing, and manipulating it.
                       Output (Processed Data):  After  processing,  the  computer  provides  the  final  result  as
                     organised and useful information, which is also called output.
                       Storage: This is the process of saving data, whether raw or processed, for future use.

                  Working of a Computer (IPO)
                  The IPO cycle is a simple model that explains how computers turn raw data into useful information.
                  It has three main steps:

                       Input: The raw data is given to the computer using input devices.
                       Processing: The computer works on the input data to change it into meaningful information.
