2. INTRODUCTION
Computer is an electronic device which takes
data as input after processing the data
computer provide output in the form of result.
CPU is central processing unit.
RAM random access memory
ROM read only memory.
Computer use in every
hospital,college,orgnization,home ,etc.

3. COMPUTER
• Computer is an electronic device which takes
data as input after processing the data computer
provide output in the form of result.
• Or
• A computer is a programmable device that
stores, retrieves, and processes data. ... The term
was later given to a mechanical device as they
began replacing the human computers.
Today's computers are electronic devices that
accept data (input), process that data, produce
output, and store in the form of result.

4. CPU
• Stands for "Central Processing Unit." The CPU is the
primary component of a computer that processes instructions. It
runs the operating system and applications, constantly
receiving input from the user or active software programs. It
processes the data and produces output, which may stored by an
application or displayed on the screen.
• The CPU contains at least one processor, which is the actual chip
inside the CPU that performs calculations. For many years, most
CPUs only had one processor, but now it is common for a single CPU
to have at least two processors or "processing cores." A CPU with
two processing cores is called a dual-core CPU and models with four
cores are called quad-core CPUs. High-end CPUs may have six (hexa-
core) or even eight (octo-core) processors. A computer may also
have more than one CPU, which each have multiple cores. For
example, a server with two hexa-core CPUs has a total of 12
processors.

5. RAM
RAM (Random Access Memory) is the hardware in a
computing device where the operating system (OS),
application programs and data in current use are kept so
they can be quickly reached by the device's processor.
RAM is the main memory in a computer, and it is much
faster to read from and write to than other kinds of
storage, such as a hard disk drive (HDD), solid-state drive
(SSD) or optical drive. Random Access Memory is volatile.
That means data is retained in RAM as long as the
computer is on, but it is lost when the computer is turned
off. When the computer is rebooted, the OS and other
files are reloaded into RAM, usually from an HDD or SSD.

6. ROM
Stands for "Read-Only Memory." Please do not
confuse this term with RAM or a hard drive, as
many people already do. ROM is memory
containing hardwired instructions that the
computer uses when it boots up, before the
system software loads. In PCs, the instructions
are read from a small program in the ROM,
called the BIOS (Basic Input/Output System).

7. USES OF COMPUTER
• Computer is used for most of the things in our life and in the
upcoming time of future, computer gonna be everything in
everyone’s life on which life will badly depend. There are the
following uses of computer are:
• For filling online forms
• For banking purpose
• In hospitals like ICU
• In coding and programming
• For communication
• For playing games
• For designing
• For education purpose
• Uses in business and marketing
