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.

10. Memory
Management
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.

11. Process Management
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
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.
