Second generation computers were developed during 1956 - 1963.

TAL Manufacturing Solutions, a wholly owned subsidiary of Tata Motors, on 11 April 2017 launched India’s first industrial-articulated robot and it goes by the name “BRABO”.

– BRABO is meant to complement the human workforce and perform repetitive, high volume, dangerous and time-consuming tasks from raw material handling to packaging of finished products.

– This is the first time that an industrial robot has been conceptualised, designed and manufactured in India. It is expected to increase productivity by 15-30%, with a payback period of 15 to 18 months.

Fragmentation occurs in a dynamic memory allocation system when many of the free blocks are too small to satisfy any request. 

External Fragmentation: External Fragmentation happens when a dynamic memory allocation algorithm allocates some memory and a small piece is left over that cannot be effectively used. If too much external fragmentation occurs, the amount of usable memory is drastically reduced. Total memory space exists to satisfy a request, but it is not contiguous. 

Internal Fragmentation: Internal fragmentation is the space wasted inside of allocated memory blocks because of restriction on the allowed sizes of allocated blocks. Allocated memory may be slightly larger than requested memory; this size difference is memory internal to a partition, but not being used

Dispatcher module gives control of the CPU to the process selected by the short-term scheduler; this involves: Switching context, Switching to user mode, Jumping to the proper location in the user program to restart that program, dispatch latency – time it takes for the dispatcher to stop one process and start another running.
