COMPUTER SCIENCE
Computer science studies computers and
computing and their theoretical and practical
applications. Computer science applies the
principles of mathematics, engineering, and logic
to many functions, including algorithm
formulation, software and hardware development,
and artificial intelligence.

WHAT IS COMPUTER?
A computer is an electronic device, operating under
the control of instructions stored in its own memory that
can accept data (input), process the data according to
specified rules, produce information (output), and store the
information for future use.
Data is an unprocessed collection of elements that might
contain text, numbers, photos, audio, and video.

INFORMATION TECHNOLOGY
Information Technology is a general
term that describe any technology that
helps to produce, manipulate, store, and
disseminate information. A combination of
computer and communication devises.

ANALOG COMPUTERS
• An Analog Computer is a special type of
computer, that can store analog data in
continuous physical quantities like electrical
potential, fluid pressure, or mechanical motion,
and finally, it produces the result with the use of
measures.
• Analog data are data or information that is
continuous. These are data that are continually
changing and don’t have discrete values.

DIGITAL COMPUTERS
• Digital computers are devices that can solve problems
by processing information in discrete form. It
operates on data including magnitudes, letters, and
symbols that are expressed in binary forms and are
also known as electronic computers.
• It can perform arithmetic and logical operations.
Some examples of digital computers include laptops,
desktops, and other electronic devices like
smartphones. Examples of digital computers are
Digital cameras, modern computers, digital watches,
scanners, etc.

PERSONAL COMPUTER
• It is a single-user computer system equipped with a
powerful CPU.
• A personal computer, sometimes known as a PC, is a tiny
and relatively affordable computer that has been particularly
built for individual use.
• These devices are based on microprocessor technology,
manufacturers may fit a whole CPU on a single chip.

WORKSTATION COMPUTER
• Workstations are computers that are specifically configured to meet
the most demanding technical computing requirements. To be
considered a workstation, systems must include key capabilities
related to performance, reliability, data integrity, scalability, and
expandability.
• It is also a single-user computer system, but it has a more powerful
microprocessor.
• A workstation is a computer that is used explicitly for engineering
applications like CAD/CAM. Workstations can also be used for
software development, desktop publishing, and developing other
types of applications.
• All these tasks require a moderate amount of computing power and
relatively high-quality graphics capabilities

MINICOMPUTER
• It is a computer system with several users. It can support at
the same moment, there are hundreds of users.
• It is a medium-sized multi-processing facility. system.
Minicomputers may accommodate up to 250 concurrent
users.
• These devices often contain two or more CPUs. It is rather
common for Institutes and departments will use
minicomputers.
• Accounting, inventory management, and billing are all
topics covered.

MAINFRAME COMPUTER
• It is a computer system that may be shared by several people. It can
sustain hundreds of users at once. In terms of software technology,
it differs from minicomputers.
• A mainframe computer system is a large and expensive computer
system. A mainframe is often capable of handling hundreds of
thousands of concurrent users.
• These devices run numerous programs at the same time and permit
multiple concurrent executions of applications.
• Mainframe computers are typically employed in big businesses that
require the processing and management of enormous amounts of
data, such as the telecom and banking sectors.

SUPERCOMPUTER
• It is an incredibly fast computer system that can execute
hundreds of millions of instructions every second.
Supercomputers are one of the fastest computers in the
world.
• These computers are costly and are only employed for
specialized applications that require many mathematical
calculations or number crunching.
• For example, supercomputers' tasks are animated graphics,
scientific simulations, weather forecasting, and geological
data analysis in industries like petrochemical prospecting,
fluid dynamic calculations, nuclear energy research, and
electronic design.
