  2. 2. History of Operating System<br />History of operating system is one of years of experimentation. Operating system was absent in the first commercial form of electronic computer launched in 1940's. Rows of mechanical switches were used to enter programs. At that time programming languages were not in use. Naturally there was hardly any idea about operating system. <br />The next generation of computers was introduced in the early phase of 1950's. The earliest version of operating system was used by the General Motors Research Laboratories. IBM 701 was the first operating system equipped computer architecture. It was a major mark in the history of operating system. This type of computer system was known as batch processing system. <br />
  3. 3. An operating system<br />is a set of system software programs in a computer that regulate the ways application software programs use the computer hardware and ways that user control the computer.<br />

  14. 14. Memory Management <br />Memory management is the act of managing computer memory. In its simpler forms, this involves providing ways to allocate portions of memory to programs at their request, and freeing it for reuse when no longer needed. The management of main memory is critical to the computer system.<br />
  15. 15. Process Management<br />Process management is an integral part of any modern day operating system. The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization <br />among processes. To meet these requirements, the OS must maintain a data structure for each process, which describes the state and resource ownership of that process and which enables the OS to exert control over each process. <br />Great Answer Not Helpful Report <br />
