COMPUTER FUNDAMENTALS

Detailed explanation-1: -Multithreading is a technique which allows a CPU to execute many tasks of one process at the same time. These threads can execute individually while sharing their resources.

Detailed explanation-2: -The instruction that the CPU fetches from memory determines what the CPU will do. In the decode step, performed by binary decoder circuitry known as the instruction decoder, the instruction is converted into signals that control other parts of the CPU.

Detailed explanation-3: -A multicore processor is an integrated circuit that has two or more processor cores attached for enhanced performance and reduced power consumption. These processors also enable more efficient simultaneous processing of multiple tasks, such as with parallel processing and multithreading.

Detailed explanation-4: -Single CPU systems use scheduling and can achieve multi-tasking because the time of the processor is time-shared by several processes so allowing each process to advance in parallel. So a process runs for some time and another waiting gets a turn.
