This is the course of basic computer which is on my YouTube channel Binary Dose. If you want to understand these topic in detail Kindly visit to my YouTube channel https://youtu.be/ghw8xn260DE

1. Introduction of
Computer
What is computer?
Basic application of Computer.
Components of Computer.

2. What is Computer?
● Computer derive its name from computer means calculations.
● Computer is not only limited to computation, but also used for
making phone calls, maintaining databases, listening songs,

of data and instruction from the user and process them to
generate useful and desired output.
● It stores the input output
for future preference.
● The advantage lies in its
processing speed and
storage capacity.

4. Basic application of computer
Mathematical Calculations:
Thanks to computers, which have computing speeds of over a million
calculations per second we can perform the biggest of mathematical
calculations.
Banks:
All financial transactions are done by computer software. They provide
security, speed and convenience.

5. Basic application of computer
Travel:
One can book air tickets or railway tickets and make hotel reservations

body. Software is used for performing surgery. Computers are used to store
patient data.
Washing Machines, ATM machines, Marriages, Examination, Certificates,
Weather forecasting are other application of software.
