Answer:
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry within a computer that executes instructions that make up a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry,[1] and specialized processors such as graphics processing units (GPUs).
ADVANTAGES :
It is simple and easy to understand.
DISADVANTAGES :
1) The process with less execution time suffer i.e. waiting time is often quite long.
2) Favors CPU Bound process then I/O bound process.
3) Here, first process will get the CPU first, other processes can get CPU only after the current process has finished it’s execution. Now, suppose the first process has large burst time, and other processes have less burst time, then the processes will have to wait more unnecessarily, this will result in more average waiting time, i.e., Convey effect.
4) This effect results in lower CPU and device utilization.
5) FCFS algorithm is particularly troublesome for time-sharing systems, where it is important that each user get a share of the CPU at regular intervals.
