Q. Limitations of execution of instructions?
1. Size of memory shown in 16 words while instruction is capable of addressing 210 =1 K words of Memory. However why 210 since 10 bits are reserved for address in machine instruction format.
2. Instructions shown are sequential in nature but a machine instruction may also be a branch instruction which causes change in sequence of instruction execution.
3. When does CPU stop executing a program? A program execution is usually finished at the end of a program or else it can be terminated because of an error in program execution or sometimes all running programs will be terminated because of catastrophic failures like power failure.

Q. Diffrence between RISC and CISC architecture? CISCs provide better support for high-level languages since they include high-level language constructs such as CASE, CALL etc
Can we specify the next screen number with a variable:- Yes, we can specify the next screen number with a variable.
What is time slicing? With this technique each program runs for a short period known as a time slice, and then another program runs for its time slice and so on.
Explain optimizing transformations? Optimizing transformations: It is a rule for rewriting a segment of a program to enhance its execution efficiency without influencing i
Network address prefixed by 1110 is a? Network address prefixed through 1110 is a multicast address.
Write a program to find the area under the curve y = f(x) between x = a and x = b, integrate y = f(x) between the limits of a and b. The area under a curve between two points can b
Q. What is Status Control and Registers? Status Control and Registers: These registers can't be used by programmers though are used to control CPU or execution of a program.
