3. Father of Computer
Charles babbage
Charles Babbage, a British Mathematics professor, is regarded as the
Father of Computers.
He was born in England in 1792 as the son of a rich banker from
Devon.
He invented the first mechanical Computer during the period 1830 to
1850. This computer called as Babbage's Analytical Engine performed
basic mathematical function.
This is used in modern computer design, so he is known as Father of
computer.
5. What is computer ?
The term ‘computer’ is derived from the word ‘compute’ which means
to ‘calculate’.
Computer are automatic electronic devices that can perform complex
tasks by breaking them into simple calculations and doing them
extremely quickly.
Computer is a machine that takes input in a specific form, processes
it and gives the output.
A computer can nothing by itself, but once it is told how to do a job,
it does it much faster than a human being.
They have ability to store, manipulate, and communicate information.
6. HISTORY
Originally calculations were computed by humans, whose
job title was computers.
These human computers were typically engaged in the
calculation of a mathematical expression.
The calculations of this period were specialized and
expensive, requiring years of training in mathematics.
The first use of the word "computer" was recorded in 1613,
referring to a person who carried out calculations, or
computations, and the word continued to be used in that
sense until the middle of the 20th century.
7. COMPUTER SYSTEM
Computer system is a collection of Entites (hardware, software
and liveware)that are designed to receive, process, manage and
present information in a meaningful format.
Any computer system will function properly and successfully if
and only if it will have following four sub systems in it:
1.Hardware
2.Software
3.Data
4.User
