1.list five major advancements and the resulting development in computer over the year?
Answers
Explanation:
Computers have evolved and advanced significantly over the decades since they originated. Many years ago, in their most rudimentary form, computers were very large and slow. Gradually, computers have become smaller and faster, enabling people to use them virtually anywhere......

The vacuum tube controlled the electric current through a sealed container. The container was often made of thin transparent glass in a rough cylinder shape. The magnetic drum is a metal coated cylinder with magnetic iron-oxide material which stored data and programs.
The ENIAC (Electric Numerical Integrator and Computer) was created by John Mauchly and John Presper Eckert. The ENIAC contained 17,468 vacuum tubes, 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. It covered 1800 square feet of floor space and weighed 30 tons. In one second, the ENIAC could workout 5,000 additions, 357 multiplications or 38 divisions. Because vacuum tubes are used instead of switches and relays in increases the speed of the calculations, but it took technicians weeks to re-program and the machine required many hours of maintenance – 24 hours a day!
There were many problems with the first generation computers, like many things when they start out. They were very expensive to make and run, slow and had limited application capabilities. They also generated a lot of heat and used large amounts of electricity, the ENIAC used 160 kilowatts of electrical power!
