RISC architecture - computer architecture:
What is reduced regarding it? The answer of this question is that to make all instructions the equal length the number of bits that are used for the opcode is reduced. Accordingly fewer instructions are provided. The instructions that were thrown out are the less significant string and BCD (binary-coded decimal) operations. Acutely, now that memory access is limited there aren't various kinds of MOV instructions or ADD instructions. Therefore the previous architecture is called CISC (Complete Instruction Set Computer). RISC architectures are also known as LOAD/STORE architectures.
The number of registers in RISC is typically 32 or more. The first the MIPS 2000 and RISC CPU has 32 GPRs as different to 16 in the 68xxx architecture and 8 in the 80x86 architecture. The only disadvantage of RISC is the code size of it. Typically more instructions are required and there is a waste in short instructions (POP, PUSH).
Multithreaded Architecture: It is clear now that if we give many contexts to multiple threads, then processors with multiple contexts are known as multithreaded systems. These sys

Q. How to calculate Colour Depth? Colour Depth (or number of Colour Planes) is number of bits assigned to every pixel to code colour information in it. These are also known as
A class is made abstract by declaring one or more of its virtual functions to be pure. A pure virtual function is one with an initializer of = 0 in its declaration
Q. If a plane is in the air also there is a fly flying inside the plane does the plane get heavier when the fly lands? Answer:- It is true that a fly puts weight on a plan
What is said to be side effect? When a location other than one explicitly named in an instruction as a destination operand is affected, the instruction is said to have a side e

It happens when two or more processes are reading or writing some joint data and the final result depends on who runs exactly when.
What is write-through protocol? For a write operation using write-through protocol during write-hit: The cache location and the major memory location are updated concurrently.
What is the difference between char a[] = "string"; and char *p = "string";? Ans) In the first case 6 bytes are assigned to the variable a which is fixed, where as in the secon
