What is a Computer?

Computer is an electronic machine that can program,

and carry out sequences of arithmetic,

or logical operations automatically.

it collects, store and retrieve data,

in form of encoded information,

and it uses this information to solve problems.

The word program may use brain images,

of students in a college computer lab.

Modern computers can perform,

generic sets of operations known as programs.

There are different types around the world,

that have different particular set of programs installed.

Programs enable it to perform a wide range of tasks.

The software is design to simplify,

the process of making data processing efficient.

It typically works with information, text and images.

and it can run a lot of programs and software.

This type of program is responsible,

for running various automated functions inside the computer.

Some application is use,

to manipulate graphics and other data,

in an organized fashion.

It helps companies bridge the gap between,

human-based and computer-based tasks.

Computers power the Internet,

which links billions of other computers and users.

it was used for calculation.

Simple manual instruments like the abacus,

aid people in doing calculation in ancient times.

Early in the Industrial Revolution,

some mechanical devices built,

to automate long tedious tasks,

like guiding patterns for looms.

More advance electrical machines did specialize,

analog calculations in the early 20th century.

The first digital electronic calculating machines,

which develop in World War II

Information About Computer

A modern computer consists of one processing element,

typically a central processing unit (CPU),

in form of a microprocessor,

along with some type of computer memory,

typically semi conductor memory chips.

The processing element carries out,

arithmetic and logical operations,

sequence, and control unit can change,

the order of operations in response to stored information. 

Peripheral devices include

input devices:keyboards, mice, joystick,

output devices: monitor screens, printers,

and input/output devices that perform both functions,

is the 2000s-era touchscreen.

Peripheral devices allow information to be retrieved,

from an external source and they enable,

the result of operations to be saved and retrieved.

Computer History

The use of abacus was for arithmetic tasks.

The Roman abacus was developed from,

devices used in Babylonia as early as 2400 BC.

After, many other forms of reckoning boards or tables have been invented.

In a medieval European counting house,

a checkered cloth would be placed on a table,

and markers moved around on it according to certain rules,

as an aid to calculating sums of money.

The First computer was made by Charles Babbage,

an English mechanical engineer and polymath,

originated the concept of a programmable computer.

Considered the “father of the computer”, 

he conceptualized and invented the first mechanical computer,

in the early 19th century.

After working on his revolutionary difference engine

designed to aid in navigational calculations,

In 1833 he realized that a much more general design,

an Analytical Engine, was possible.

The input of programs and data was,

to be provided to the machine via punched cards,

a method being used at the time to direct,

is the mechanical looms like the Jacquard loom.

For output, the machine would have a printer,

a curve plotter and a bell.

The machine will be able,

to punch numbers into cards to read.

The Engine incorporated an arithmetic logic unit,

control flow in the form of conditional branching and loops,

and integrated memory, making it the first design,

for a general-purpose computer that could be,

described in modern terms as Turing-complete.
