Computers

"A computer is a machine that manipulates data according
to a list of instructions. The ability to store and execute lists of
instructions called programs makes computers extremely versatile and
distinguishes them from calculators. The Church–Turing thesis is a mathematical
statement of this versatility: any computer with a certain minimum capability
is, in principle, capable of performing the same tasks that any other computer
can perform. Therefore, computers with capability and complexity ranging from
that of a personal digital assistant to a supercomputer are all able to perform
the same computational tasks given enough time and storage capacity.

Notes
“The first devices that resemble modern computers date to the mid-20th
century (1940–1945), although the computer concept and various machines similar
to computers existed earlier. Early electronic computers were the size of a
large room, consuming as much power as several hundred modern personal
computers(PC). Modern computers are based on tiny
integrated circuits and are millions to billions of times more capable while
occupying a fraction of the space. Today, simple
computers may be made small enough to fit into a wristwatch and be powered from
a watch battery. Personal computers, in various forms, are icons of the
Information Age and are what most people think of as "a computer"; however, the
most common form of computer in use today is the embedded computer. Embedded
computers are small, simple devices that are used to control other devices — for
example, they may be found in machines ranging from fighter aircraft to
industrial robots, digital cameras, and children's toys.”
