Q. Explain working of Counters?
A counter is a register that goes through a predetermined sequence of states when clock pulse is applied. In principle value of counters is increased by 1 module the capacity of register it implies that when value stored in a counter reaches its maximum value next incremented value becomes zero. Counters are mostly used in circuits of digital systems where control and sequence operations are performed for illustration in CPU we have program counter (PC).
Counters can be categorized in two categories based on the manner they operate: Asynchronous and synchronous counters. In Asynchronous counters change in state of one flip-flop triggers other flip-flops. Synchronous counters are relatively faster since state of all flip-flops can be changed at the same time.

Q. Explain Addressing modes in RISC? Simple addressing modes: Another benefit is the use of simple addressing modes. RISC machines employ simple register addressing having disp
Can we define our own Match Code ID's for SAP Matchcodes? Yes, the number 0 to 9 are reserved for us to make our own Match Code Ids for a SAP described Matchcode object.
Q. Can a vector have a component equivalent to zero and still have a nonzero magnitude? Answer:- Yes For example the 2-dimensional vector (1, 0) has length sqrt (1+0) = 1
