10 Questions
What is a computer system?
A computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster.
What are some examples of products that use computers as control systems?
Examples include simple special-purpose devices like microwave ovens and remote controls, as well as factory devices like industrial robots and computer-aided design, and general-purpose devices such as personal computers and mobile devices such as smartphones.
What is the historical significance of early computers?
Early computers were meant to be used only for calculations. 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 machines did specialized analog calculations in the early 20th century.
How do modern digital electronic computers perform operations?
Modern digital electronic computers can perform generic sets of operations known as programs, which enable computers to perform a wide range of tasks.
What role do computers play in the Internet?
Computers power the Internet, which links billions of computers and users, enabling communication and data exchange on a global scale.
