A computer is a machine that performs processes and calculations based on instructions from software or hardware programs. It can increase productivity, connect to the internet, store vast amounts of information to reduce waste, help organize and search information, and help users learn and be informed. Input devices like keyboards, mice, and scanners provide data to computers, while output devices like monitors, projectors, speakers and printers send data from computers. The main components of a computer are the control unit, memory unit, and arithmetic logic unit. Computer hardware refers to the physical parts of a computer while software refers to instructions that can be run on hardware.

OF
COMPUTER
4. In computing, an input device is a
piece of computer hardware
equipment used to provide data and
control signals to an information
processing system such as a
computer or information appliance.
INPUT DEVICES
Examples of input devices include
keyboards, mouse, scanners,
digital cameras and joysticks
7. An output device is
any device used to send data
from a computer to
another device or user. Most
computer data output that is
meant for humans is in the form
of audio or video. Thus,
most output devices used by
humans are in these categories.
ABOUT OUTPUT DEVICES
Examples include monitors,
projectors, speakers,
headphones and printers.
9. The control unit (CU) is a
component of a computer's
central
processing unit (CPU) that
directs the operation of the
processor.
CONTROL UNIT (CU)
It tells the computer's
memory, arithmetic and
logic unit and input and
output devices how to
respond to the instructions
that have been sent to the
processor.
10. Memory unit is the amount of
data that can be stored in the
storage unit. This storage
capacity is expressed in terms
of Bytes.
MEMORY UNIT (MU)
11. An arithmetic logic unit is a combinational digital
electronic circuit that performs arithmetic and
bitwise operations on integer binary numbers. This is
in contrast to a floating-point unit, which operates
on floating point numbers. This is in contrast to
a floating-point unit (FPU), which operates
on floating point numbers. An ALU is a fundamental
building block of many types of computing circuits,
including the central processing unit (CPU) of
computers, FPUs, and graphics processing
units (GPUs). A single CPU, FPU or GPU may
contain multiple ALUs.
ARITHMETIC LOGICAL
UNIT (ALU)
12. Computer hardware
includes the physical,
tangible parts or
components of a computer,
such as the cabinet, central
processing unit, monitor,
keyboard, computer data
storage, graphics card,
sound card, speakers and
motherboard. By contrast,
software is instructions
that can be stored and run
by hardware.
COMPUTER HARDWARE
13. Computer
software, or simply
software, is a
collection of data
or computer
instructions that
tell the computer
how to work.
COMPUTER SOFTWARE
This is in contrast to physical hardware,
from which the system is built and actually
performs the work.
19. We have our own Centre library that has sufficient books of
great authors for our students. Notes prepared by our
teachers are provided to every student for their review. We
also provide particular software's to our students on which
they are pursuing their course. Extra classes are given to
those students who need some extra time or in case of class
miss due to some reason. We have our own placement cell
that conduct interviews for students of various courses in
order to give a good start to their career, because we make
our students so capable that they become able to crack any
interview. The reason behind it is that we not only give
training in particular Computer Courses but also trained them
to crack any interview with special personality development
classes, which helps them a lot.
