1. “AN ORIENTATION”

4. COMPUTER ???
• A computer is an electronic device, operating under the
control of instructions (software) stored in its own
memory unit, that can accept data (input), manipulate
data (process), and produce information (output).
• A computer is a general purpose device that can be
programmed to carry out a set of arithmetic or logical
operations.
• A computer consists of at least one processing element,
typically a central processing unit (CPU) and some form
of memory.
• The processing element carries out arithmetic and logic
operations, and a sequencing and control unit that can
change the order of operations based on stored
information.

6. What Does A Computer Do?
Computers can perform four general operations,
which comprises the information processing cycle.
 Input
 Process
 Output
 Storage
The basic functions that a computer generally
performs in its basic cycle of computation.

7. Why Is A Computer So Powerful?
• The ability to perform the
information processing cycle
with amazing speed.
• Reliability (low failure rate).
• Accuracy.
• Ability to store huge amounts
of data and information.
• Ability to communicate with
other computers.

8. WHAT IS COMPUTER SCIENCE?? :-
•Computer science (abbreviated CS )is the scientific and
practical approach to computation and its applications.
•It is the systematic study of the feasibility, structure,
expression, and mechanization of the algorithms.
•Its subfields can be divided into a variety of theoretical and
practical disciplines , Some fields, such as
computational complexity theory are highly abstract, while
fields such as computer graphics emphasize real-world visual
applications.
•Still other fields focus on the challenges in implementing
computation. For example, programming language theory.

9. Name Of The Field :-
• The term "computer science" appears in a 1959 article in
Communications of the ACM
• Danish scientist Peter Naur suggested the termdatalogy, to reflect
the fact that the scientific discipline revolves around data and data
treatment, while not necessarily involving computers. The first
scientific institution to use the term was the Department of Datalogy
at the University of Copenhagen, founded in 1969, with Peter Naur
being the first professor in datalogy.
• The term computics has also been suggested.
• Edsger Dijkstra, states that "computer science is no more about
computers than astronomy is about telescopes."The design and
deployment of computers and computer systems is generally
considered the province of disciplines other than computer science.

10. EVOLUTION :-
The evolution of computer technology is a fascinating journey to
review and examine. This is because with a thorough
understanding of their evolution you can not only look toward
the future of computers, you can also recognize other
developments across the world that may in fact lead back to
anticipating their future application and in turn the future of
computers.
The evolution of computers is a study in the power of necessity
to drive innovation. There are thousands of underlying
developments and adaptations that occurred throughout this
time. Each innovation could be analyzed to show how small
leaps forward contributed to large leaps forward such as the
transistor or integrated circuit. Each of these having a history of
development that could fill pages of detail.

12. AREAS OF COMPUTER SCIENCE:-
computer science spans a range of topics from theoretical
studies of algorithms and the limits of computation to the
practical issues of implementing computing systems in
hardware and software.
