VARIOUS ARCHITECTURE OS
1. Single processor system
• Most systems use single processor systems.
• They perform only one process at a given time, and it carries out the
next process in the queue only after the current process is completed.
• OS monitors the status of them and also sends them next executable
instruction.
• On a single-processor system, there is one main CPU capable of
executing a general-purpose instruction set, including instructions
from user processes.
• It is suitable for general purpose computers , as it cannot run multiple
processes in parallel.
