it led to a boom in computer manufacturing that gave computing power in the form of microcomputers to homes and schools.
As microcomputer became more popular,many companies began producing software that could be run on the smaller machines.most of the early software was written for games . Later,instructional programs began to appear. One important software development was VisiCalc,the first electronic spreadsheet for microcomputers . It was introduced in 1979 and greatly increased the uses of microcomputers in the business world . More and more software was developed for a variety of applications, ranging from business to home and school.
After that , very large scale integration (VLSI) is replacing large scale integration . This further miniaturization of integrated circuits offers even greater improvements in price , performance , and size of computers . A microprocessor based on VLSI is more powerful than an entire roomful of 1950s computer circuitry .
