Computer 1s the most powerful man has ever created.Computers have made a great impact on
our every day life. There presence is felt at almost every working place viz. Homes, college, office,
industries, hospital, banks, retail, store, railway, research, and design organizations and so on. Computers,
large and small, are used nowadays by all kinds of people for a variety of takes in a modern and
industrialized society.
Computers are extremely versatile. In fact, they are universal information-processing machines.
According to the Church-Turing thesis a computer with a certain minimum threshold capability is in
principle capable of performing the tasks of any other computer, from those of a personal digital assistant
to a supercomputer, as long as time and memory capacity are not considerations. Therefore, the same
computer designs may be adapted for tasks ranging from processing company payrolls to controlling
unmanned spaceflights. Due to technological advancement, modern electronic computers are experientilly more capable than those of preceding generations (a phenomenon partially described by
Moore s Law)
Computers take numerous physical forms. Early electronic computers were
the size of a large room, and such enormous computing facilities still exist for
Specialized scientific computation-supercomputers and for the transaction
processing requirements of large companies, generally called mainframes. Smaller
computers for individual use, called personal computers, and their portable
equivalent, the laptop computer, are ubiquitous information-processing and
Communication tools and are perhaps what most non-experts think of as a
computer". However, the most common form of computer in use today is the
embedded computer, small computers used to control another device.
Embedded computers control machines from fighter aircraft to digital
cameras. So we can say that, A computer is basically a programmable
computing, machine. Earlier computer were use for complex
computations and use by only scientist and engineers. These computers
being very fast can be used not only for computation but also to store
and retrieve information, to control certain processes and machine, to
measure and display certain physical and electrical quantities.
