A computer is machine that can be programmed to automatically carry out
sequences of arithmetic or logical operation (computation).Modern digital
electronic computer can perform generic sets of operation known as
programs.
These program enable computer to perform a wide range of tasks. The term
computer systems may refer to a nominally complete that includes the
hardware, software and peripheral equipment needed and used for full
equipment operation, or to a group of computers that are linked and function
together, such as computer network or computer cluster.
A broad of industrial and consumer products use computers as control
system, including simple special purpose devices like microwave ovens and
remote controls and factory device like industrial robots. Computer are at the
core of general purpose devices such as personal computer and mobile
devices such as smartphone. Computer power the Internet, which links
billions of computer and users.
Early computer were meant to be used only for calculation. Simple manual
instruments like the abacus. Have aided people in doing calculations since
ancient times. Early in the industrial revolution, some mechanical devices
were built to automate long tedious tasks, such as guiding patterns for
looms.
More sophisticated electrical machine did specialised analogue calculation in
the early 20th century. The first digital electronic calculating machine were
developed during second world War, both electro mechanical and using
thermionic valves. The first semiconductor transistors in the late 1940s were
followed by the silicon based MOSFET (MOS transistor and monolithic
integrated circuit chip technologies in the late 1950s, leading to the micro
processor and the micro computer revolution in the 1970s. The speed power
and versatility ever since then, with transistor counts increasing at a rapid
pace (Moore’s law) note that counts double every two years, leading to the
digital revolution during the late 20th and early 21st centuries
Conventional, a modern computer consists of at least one processing
element, typical processing unit (CPU) in the form of a microprocessor,
together with some type of computer memory, typical semiconductor
memory chips. The processing element carries out arithmetic and logical
