Discuss about the Electronic computer

The first general function programmable electronic computer was the Electronic Numerical Integrator and Computer (ENIAC), built by John V and J. Presper Eckert.

The trends that were encountered during era of first generation computer were as:

• All control of First generation computer was centralized in single CPU and all operations required a direct intervention of CPU.
• Ferrite-core main memory use was started during that time.
• Ideas such as use of index register and virtual memory.
• Input device were punched cards.
• Magnetic drums and magnetic tapes were used as secondary memory.
• Machine language or Binary code was used for programming.
• Towards end due to difficulties encountered in use of machine language as programming language, use of symbolic language that is now called as assembly language started.
• Assembler was a program, that translates assembly language programs to machine language, was made.
• Computer was accessible to only a single programmer at a time (single user environment).
• Advent of Von-Neumann Architecture.
