2. A computer is an electronic device that can receive, store, process, and output data. It
is a machine that can perform a variety of tasks and operations, ranging from simple
calculations to complex simulations and artificial intelligence.
Computers consist of hardware components such as the central processing unit
(CPU), memory, storage devices, input/output devices, and peripherals, as well as
software components such as the operating system and applications.

2. Diligence :
A human cannot work for several hours without resting, yet a computer
never tires. A computer can conduct millions of calculations per second
with complete precision without stopping
1. Speed :
Executing mathematical calculation, a computer works faster and more accurately
than human. Computers have the ability to process so many millions (1,000,000) of
instructions per second.

3. Reliability :
A computer is reliable. The output results never differ unless the input varies. the
output is totally depend on the input. when an input is the same the output will also
be the same.
5. Versatility :
Versatility refers to a capacity of computer. Computer perform different types
of tasks with the same accuracy and efficiency. A computer can perform
multiple tasks at the same time this is known as versatility.

5. TypesTypes OfOf ComputersComputers
There are two bases on which we can define the types of computers.
We will discuss the type of computers on the basis of size and data
handling capabilities.
Types Of Computers Are:
Super Computer.
Mainframe Computer.
Mini Computer.

8. INPUT DATA:
This refers to collecting the data and instructions being
given by the user. It can also be termed as Data Capturing.
OUTPUT DATA:
This refers to producing the output on the output devices
once the result is calculated.

9. DATA PROCESSING:
This refers to processing the given data according to the
given instructions and producing the required output.
DATA STORAGE:
The data is required to be stored at various levels while
processing, before processing, or even after processing to
store desired results. This is data storage.
