In a multiprocessor system there exist several caches each may containing a copy of same variable A. Then a change in one cache should immediately be reflected in all other caches this process of maintaining the same value of a data in all the caches s called cache-coherency.

Sending a message to a group is called multicasting, and its routing algorithm is called multicast routing

IEEE 1394 (Firewire) supports the maximum of 63 connected devices with speeds up to 400 Mbps.

A binary semaphore is one, which takes only 0 and 1 as values. They are used to implement mutual exclusion and synchronize concurrent processes.

Hard real-time systems required to complete a critical task within a guaranteed amount of time.
Soft real-time computing requires that critical processes receive priority over less fortunate ones.

compiler is used to translate the high-level language program into machine code at a time. It doesn't require special instruction to store in a memory, it stores automatically. the execution time is less compared interpreter.

A compiler is a program that translates a source program written in some high-level programming langualge (such as Java) into machine code for some computer architecture (such as the Inter Pentium archiecture).

You can divide the frequency of a clock by just implementing T Flip flop.

Give clock as clock input and tie the T input to logic 1.

Stack pointer is a special purpose 16-bit register in the Microprocessor, which holds the address od the top of the stack.
