Q. Era of first generation computers?

The trends that were encountered at the time of the era of first generation computers were:

• Centralized control in a single CPU (all the operations needed a direct intervention of the CPU).
• Use of ferrite-core main memory was begun during this time.
• Concepts like use of virtual memory and index register started.
• Punched cards were used for input device.
• Magnetic drums and magnetic tapes were used as secondary memory.
• Machine language or binary code was used for programming.
• Towards the end because of difficulties encountered in use of machine language as programming language. The use of symbolic language that is now called as assembly language started.
• Assembler a program that converts assembly language programs to machine language was developed.
• Computer was available to only one programmer at a time (single user environment).
• Advent of von-Neumann architecture.
