Computer

2.  Many people throughout history are credited with developing early
prototypes that led to the modern computer. During World War II,
physicist John Mauchly, engineer J. Prosper Eckert, Jr., and their
colleagues at the University of Pennsylvania designed the first
programmable digital computer, the Electronic Numerical Integrator and
Computer(EINAC).

3.  As of June 2020 the most powerful computer in the world is the
Japanese supercomputer Fugaku, developed by Riken and Fujitsu. It has
been used to model COVID-19 simulations.

4.  Control unit, arithmetic logic unit and memory are together called the
central processing unit or CPU. Computer devices like keyboard, mouse,
printer, etc. that we can see and touch are the hardware components of
a computer. ... Both hardware and software are necessary for working of
a computer.

5.  A computer is one type of machine manage different kinds of programs
to perform useful tasks to the users. Computer gives proper response to
the users through the set of instructions arranged in proper order. ...
Software is a process of preparing program through instructions and data.

6.  Some people say that COMPUTER stands for Common Operating
Machine Purposely Used for Technological and Educational Research. ...
"A computer is a general purpose electronic device that is used to perform
arithmetic and logical operations automatically.

7.  RAM, which stands for random access memory, and ROM, which stands
for read-only memory, are both present in your computer. RAM is volatile
memory that temporarily stores the files you are working on. ROM is non-
volatile memory that permanently stores instructions for your computer.

8.  Here are some of the popular types of computer that you can find in
use today.
 Pocket (palmtop) Computer. Pocket computers have been designed to
allow people to keep lots of information close to hand - wherever they
happen to be. ...
 Laptop Computer. ...
 Micro (desktop) Computer. ...
 Mainframe/Supercomputer.

9.  The four basic types of computers are as
under: Supercomputer. Mainframe Computer. Minicomputer.

10.  1 Supercomputer.
 2 Mainframe.
 3 Server Computer.
 4 Workstation Computer.
 5 Personal Computer or PC.
 6 Microcontroller.
 7 Smartphone.

11.  The characteristics of computers that have made them so powerful and
universally useful are speed, accuracy, diligence, versatility
and storage capacity. Let us discuss them briefly. Computers work at an
incredible speed.

12.  Computers are classified into various types based on historical
development (computer generation), purpose, technology used, and size
& storage capacity. The following figure illustrates the classification of
computers based on different criteria.

13.  Microcomputers
 Microcomputers became the most common type of computer in the late
20th century. The term “microcomputer” was introduced with the advent of
systems based on single chip microprocessors. The best-known early
system was the Altair 8800, introduced in 1975. The term "microcomputer"
has practically become an anachronism.

14.  The Memory or RAM - for Random-access memory - is an important part
of the computer as it stores data and instructions. Typically, the processor
requests information from the memory, runs calculations and stores it back
in the memory.

15. Charles Babbage
 English mathematician and inventor Charles Babbage is credited with
having conceived the first automatic digital computer. During the mid-
1830s Babbage developed plans for the Analytical Engine.

16.  The most powerful computers can perform extremely complex tasks, such
as simulating nuclear weapon experiments and predicting the development
of climate change The development of quantum computers. machines that
can handle a large number of calculations through quantum parallelism
(derived from superposition, would be able to do even more complex tasks.

17.  Basic Applications of Computer
 Home. Computers are used at homes for several purposes like online bill
payment, watching movies or shows at home, home tutoring, social media
access, playing games, internet access, etc. ...
 Medical Field. ...
 Entertainment. ...
 Industry. ...
 Education. ...
 Government. ...
 Banking. ...
 Business.

18.  The 5 different parts of a computer—taking a look under the hood
 5 parts of a computer. ...
 The motherboard. ...
 The Central Processing Unit (CPU) ...
 The Graphics Processing Unit (GPU) ...
 Random Access Memory (RAM) ...
 Storage.

19.  Central Processing Unit (CPU) ... The CPU is the brain of a computer,
containing all the circuitry needed to process input, store data, and output
results.

20.  Computer hardware includes the physical parts of a computer, such as
the case, central processing unit (CPU), monitor, mouse,
keyboard, computer data storage, graphics card, sound card, speakers
and motherboard. By contrast, software is the set of instructions that can
be stored and run by hardware.
