Several schemes available are as follows:
Pipes: One-way communication process through which different process can interact. The problem is that the two processes could have a unique ancestor. However this problem was fixed with the help of named-pipes (FIFO).
Message Queues : Message queues may be used between unrelated and related processes executing on a machine.
Shared Memory: This is the fastest of all IPC process. The memory to be shared is examined into the address space of the processes. The speed gain is attributed to the fact that there is no kernel use. But this scheme requires synchronization.
Tree structured directories: This is the main common directory structure. The tree has a root directory as well as every file in the system has a unique path name. A directory

What is meant by demand paging? Explain. Demand paging is a technique to implement virtual memory. In demand paging simply when a page is required it is brought into memory. As
Virtual File System serves two important functions. 1. It divides file-system-generic operations from their execution by defining a clean VFS interface. 2. The VFS is based
Linked list allocation: At this time the blocks are stored using linked lists. The block size require not be the same. Thus internal fragmentation is avoided. Consider

Garbage collectors trade space for time. If we collect all the time (which requires a lot of processing time), the GC allocator will use the least memory possible. On the other han
