Generations of computer  computer appreciation continued Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, and more powerful and more efficient and reliable devices. The various generations of computers a listed below: (I) First Generation (1946-1954): In 1946 there was no 'best' way of storing instructions and data in a computer memory. There were four competing technologies for providing computer memory: electrostatic storage tubes, acoustic delay lines (mercury or nickel), magnetic drums (and disks?), and magnetic core storage. The digital computers using electronic valves (Vacuum tubes) are known as first generation computers. The first 'computer' to use electronic valves (i.e. vacuum tubes). The high cost of vacuum tubes prevented their use for main memory. The vacuum tube consumes a lot of power. The Vacuum tube was d...
