What is Computer?
Computer is
an electronic device which is capable of receiving information in particular
form performing sequence of operation in accordance with a predetermined but
variable set of procedure instruction to produce a result in form of information
or signals
What is the Full Form of computer?
Technically,
the computer doesn’t have full form. In hypothetical form full form of computer
is said to be Common Operating Machine particularly used for Trade, Education
and Research.
Who founded computer?
The first
computer was the Abacus or its descendant, the slide rule invented by
digital computer in 1642.
Who is Father of computer?
The First
computer resembling today’s modern machines was an analytic engine, it was
designed by the British mathematician CharlesBabbage between 1837 and it contain an Arithmetic Logic Unit (ALU), basic
flow control, integrated memory and he is known as the “Father of Computer”.
Who is the Father of Modern computer?
Alan Turing is considered by many to be father
of modern computer science as the world knows it. He formed concept of
algorithm and computations with on his invention, the Turing machine.
Who invented the first programmable
computer?
The Z1 was
the first Electro-mechanical binary programmable Computer, build by German Konrad Zuse in his parent living room
between 1936 and 1938.
Who invented the first electric
programmable computer?
The Colossus was the first electric
programmable computer, developed by Tommy flowers and it was demonstrated in
December 1943. It was created to help the British code breakers to read
encrypted German messages.
Who invented the first digital
computer?
The first digital
computer was ENIAC was invented by J. Presper Eckert and John Mauchly at university of Pennsylvania and began construction in
1943 was not completed until 1946. It occupied about 1,800 square feet and used
18,000 vacuum tubes and weighed 50 tons.
First computer with program stored in
memory
The first
computer with program stored in memory is delivered to United States government
in the year 1950, the UNIVAC 1101 is
which the first computer capable of storing and running a program form memory.
Who made the first PC?
In, 1975 Ed Roberts coined the term “Personal
Computer” when he introduced the Altair 8800, first pc considered by many to be
KENBAK-1, which was introduced for
$750 in 1971.
Which is the First computer virus?
The very
earliest computer virus is “Creeper”
which displayed the message “I AM CREEPER: CATCH ME IF YOU CAN” were not only
innocuous experiments in computer but completely quarantined to their home
networks, this was in 1971 when there was no unified internet.
Which is the First supercomputer?
Supercomputers
were introduced in 1960’s with ATLAS at university of Manchester, the IBM 7030
stretch and series of computer at Control Data Corporation (CDC), designed by Seymour Cray. These used innovative
design Parallelism to achieve superior computational peak performance. The
Atlas officially commissioned on 7th December 1962 one of world
first Supercomputer considered most powerful computer in the world at the time
by considerable margin.
Quantum Computer
D-Wave is the world’s first company to sell
quantum computers. The D-Wave one was build on early prototype such as D-Wave’s
orion quantum computer. The Prototype was 16-qubitquantum annealing processor, demonstrated on 13 February 2007 at computer
history museum in Mountain view, California.
