1. In 1801, Joseph Marie Jacquard made an improvement to the
textile loom by introducing a series of punched paper cards as a
template which allowed his loom to weave intricate patterns
automatically. The resulting Jacquard loom was an important step in
the development of computers because the use of punched cards to
define woven patterns can be viewed as an early, albeit limited,
formof programmability.
2. It was the fusion of automatic calculation with
programmability that produced the first recognizable computers. In
1837, Charles Babbage was the first to conceptualize and design a
fully programmable mechanical computer, his analytical engine.[20]
Limited finances and Babbage's inability to resist tinkering with
the design meant that the device was never completednevertheless
his son, Henry Babbage, completed a simplified version of the
analytical engine's computing unit (the mill) in 1888. He gave a
successful demonstration of its use in computing tables in 1906.
This machine was given to the Science museum in South Kensington in
1910.
3. Computer is man made machine. Which needs electricity to
work. It is an electronic device for storing and processing data,
typically in binary form, according to instructions given to it in
a variable program. Mainly a calculating device. This is a laptop
computer.We can carry it anywhere.
4. COMPUTER AND ITS PARTS COMPUTER HARDWARE SOFTWARE
5. WHAT IS HADRWARE Hardware refers to the parts of a computer
that you can see and touch, including the case and everything
inside it. The most important piece of hardware is a tiny
rectangular chip inside your computer called the central processing
unit (CPU), or microprocessor. It's the "brain" of your computer
the part that translates instructions and performs calculations.
Hardware items such as your monitor, keyboard, mouse, printer, and
other items are often called hardware devices, or devices.
6. HARDWEAR INPUT DEVICE OUTPUT DEVICE
7. INPUT DEVICE
8. OUTPUT DEVICE
9. SOFTWARE Software refers to the instructions, or programs,
that tell the hardware what to do. A word processing program that
you can use to write letters on your computer is a type of
software.
10. The operating system (OS) is software that manages your
computer and the devices connected to it. Two well-known operating
systems are Windows and Macintosh operating system. Your computer
uses the Windows operating system
11. USES OF A COMPUTER The uses of computers is universal.
Computers are used in applications ranging from running a farm,
diagnosing a disease, and designing to constructing and launching a
space vehicle.
12. Because the development of computers has been largely the
work of scientists, it is natural that a large body of computer
applications serves the scientist. The articles included herein
relate to the uses of computers today in business, science,
education, schools, classrooms, hospitals, medicine, health care,
military, agriculture, law enforcement, at home and in our everyday
lives.
