Explanation:
Detailed explanation-1: -A fragmented disk takes longer to read from and write to, making a computer run slower. Defragmentation software takes the fragmented files and rearranges the segments so that they run contiguously. This decreases read/write time, thereby speeding up computer performance.
Detailed explanation-2: -The CPU fetches the instructions one at a time from the main memory into the registers. One register is the program counter (pc). The pc holds the memory address of the next instruction to be fetched from main memory. The CPU decodes the instruction.
