Static RAM: No refreshing, 6 to 8 MOS transistors are needed to form one memory cell, Information stored as voltage level in a flip flop.
Dynamic RAM: Refreshed periodically, 3 to 4 transistors are needed to form one memory cell, Information is stored as a charge in the gate to substrate capacitance.
Q. What is Master Clock Signal in Control Unit? The Master Clock Signal: This signal causes micro-operations to be executed in a square. In a single clock cycle either a single
In the shared-memory programming model, tasks share a common address space, which they read and write asynchronously. Several mechanisms such as locks / semaphores may be used to c
Consider that a list of record or a table is stored in the memory and you wish to find some information in that particular list. E.g. the list comprises three fields as displayed b
In primary storage device the storage capacity is fixed. It has a volatile memory. In secondary storage device the storage capacity is not limited. It is a nonvolatile memory. Prim
Explain busy waiting semaphores. Weak, Busy-wait Semaphores: The simplest method to implement semaphores. Useful while critical sections last for a short time, or we
What is multiprogramming or multitasking? The operating system manages the concurrent implementation of several application programs to make the best possible uses of computer
A three stage network is realized by using switching matrices of size p x s in stage 1, r x r matrices in stage 2 and s x p matrices in stage 3. Using the Lee's probability graph s
Subtract -27 from 68 using 2's complements. Ans. By using 2's complement 68-(-27)= 68-(-27) 2's complement representation of 68 = 01000100(64+4) 2's complement representatio
