  What is buffering

Buffering

 Buffer is a small memory area that stores data while they are transferred between two devices or between a device and CPU or one computer to another computer via Internet it is basically used to avoid to a speed mismatch between two devices for example that a file is received via modem or storage on the hard disk but the modem is so slower than the hard disc so a buffer is created in main memory to store the bytes received from the modem. When an entire buffer is full, the buffer can be written to disk. Mean while modem still a place to store data so another buffer is created and the modem then start to fill the second buffer the first buffer is written to disk. This technique is called double buffering. So we can say that buffer is a small Storage Area used to store our information temporary to eliminate for the difference in rates of data flow between various unit of a computer.

Deadlock in operating system-computer world

  Deadlock in operating system-computer world Deadlock :  In a multi-programming environment, many process may complete for a minute number of resources. A process make a request for a resource and if the resource is not available at that time, the process enter In a waiting state. A waiting state process is never again-able to change state because the resource it has requested is held by other waiting process. This situation is called deadlock. So we can say that a process is said to be deadlock when it is waiting for an event or resources which will never occurs.   so we can say that in this situation none of the process gets executed  since the resource it needs, is held by some other process which is also waits for some other resource to be released.  Let's assume that there are three process P1, P2, p3 and three different resources R1, R2 and R3. R1 is assigned to p1, R2 is assigned to P2 and R3 is assigned to P3.   After somet...

Memory management in operating system-computer world

Memory management in operating system-computer world Memory management :   The function of operating system which manages the memory of a computer for the processing of the program this management is known as memory management. There are several programs that consist in memory, so it became to move programs and data around the memory of a memory management system is the collection of hardware and software procedures for the Managing various program consisting in the memory. Memory management play an important role in operating system to improve the speed speed of the computer system.   Memory management determines how  memory is allocated between the processes,  deciding which gets memory, when they receive it and how much they are allowed. When memory is allocated it determines which memory location will be assigned. Main memory refers to a physical memory that is the internal memory of the computer. Main memory is also known as RAM. The computer is able t...
