Answer:
was probably the worst prediction in history. Back in the 1940s, Thomas Watson, boss of the giant IBM Corporation, reputedly forecast that the world would need no more than "about five computers." Six decades later and the global population of computers has now risen to something like one billion machines!
To be fair to Watson, computers have changed enormously in that time. In the 1940s, they were giant scientific and military behemoths commissioned by the government at a cost of millions of dollars apiece; today, most computers are not even recognizable as such: they are embedded in everything from microwave ovens to cellphones and digital radios. What makes computers flexible enough to work in all these different appliances? How come they are so phenomenally useful? And how exactly do they work? Let's take a closer
Answer:
1. A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks.
2. A computer works by combining input, storage, processing, and output. All the main parts of a computer system are involved in one of these four processes. Input: Your keyboard and mouse, for example, are just input units—ways of getting information into your computer that it can process.
3.Another name for a chip, an integrated circuit (IC) is a small electronic device made out of a semiconductor material. The first integrated circuit was developed in the 1950s by Jack Kilby of Texas Instrumentsand Robert Noyce of Fairchild Semiconductor.
4.Computer memory is a generic term for all of the different types of data storage technology that a computer may use, including RAM, ROM, and flash memory. Some types of computer memory are designed to be very fast, meaning that the central processing unit (CPU) can access data stored there very quickly.
