Fascinated by the success of ENIAC, the mathematician john von neumann in 1945 undertook a study of computation that showed that a computer should have a very simple, fixed physical structure, and yet be able to perform any of computation without the need for any physical change in the unit
VON NEUMANN
contributed a new awareness of how practical and fast computer should be built, these ideas,
Usually referred to as the stored - program technique, become essential for future generation of high speed digital computer and were universally adopted, according to von Neumann theory, data and program can be stored in the same memory, thus the machine can itself alter either its program or internal data,
As a result of there ideas,
Computing and programming became much faster, more flexible, and efficient,
This group of computer included EDVAC (figure 1.2) and UNIVAC, which were the first commercially available computer,
*Advancement in 1950,s - 1960, s
In Early 1950, s tow important engineering invention changed the images of the computer field, thses discoveries were the magnetic core memories and the transistor circuit elements this quickly found its way into new models of digital computer,
These machines were very expensive and were also complicated to operated, such computer were mostly found in large computer centers, government, and research and development laboratories, those computer mostly worked on a single problems at a time,
During this period, the different prices, as well as accessories such as:
- CARD Readers
- Printers
Cathode- ray- tube
These were widely used in businesses for such things as:
Accounting
Payroll
