Day 01Part 10-Gate lecture of Operating system for cse – Operating system Process state in simple way<\/p>\n
[fvplayer id=”342″]<\/p>\n
A process<\/strong> is a program in execution. It is an active entity, unlike a program, which is a passive collection of instructions.<\/p>\n An operating system handles multiple processes by tracking their states<\/strong>. These states help manage and control the execution of processes effectively.<\/p>\n Q. In a multi-programming environment, if a running process is performing an I\/O operation, its state is changed to:<\/strong> Answer:<\/strong> (C) Blocked\/Waiting<\/p>\n \u00a0Tip:<\/strong> Practice previous GATE questions on process management<\/strong> for better understanding. If you need more detailed explanations or help with problems, just ask!<\/p>\n Sure! Here’s a Day 01 \u2013 Part 10<\/strong> style explanation from a GATE CSE lecture<\/strong> on Operating System Process States<\/strong>, explained in a simple and beginner-friendly way<\/strong>.<\/p>\n A process<\/strong> is a program in execution<\/strong>. Let\u2019s understand it like a life cycle<\/strong> of a process:<\/p>\n The process is being created<\/strong>.<\/p>\n<\/li>\n Example: You clicked on a program icon, and it’s just loading.<\/p>\n<\/li>\n<\/ul>\n Process is loaded into memory<\/strong> and is waiting for CPU<\/strong>.<\/p>\n<\/li>\n It\u2019s ready to run but hasn\u2019t got the CPU yet.<\/p>\n<\/li>\n Think of it as standing in a queue<\/strong>.<\/p>\n<\/li>\n<\/ul>\n The process is currently being executed<\/strong> by the CPU.<\/p>\n<\/li>\n Only one process<\/strong> (in a single-core system) can be in running<\/strong> state at a time.<\/p>\n<\/li>\n<\/ul>\n The process is waiting for some I\/O<\/strong> (input\/output), like reading from disk or user input.<\/p>\n<\/li>\n It gives up the CPU voluntarily<\/strong> and will return to ready once the I\/O is done.<\/p>\n<\/li>\n<\/ul>\n The process has finished execution<\/strong> or is killed due to some error<\/strong>.<\/p>\n<\/li>\n It leaves the process table<\/strong>.<\/p>\n<\/li>\n<\/ul>\n Some systems also include:<\/p>\n Ready Suspended<\/strong><\/p>\n<\/li>\n Blocked Suspended<\/strong><\/p>\n<\/li>\n<\/ul>\n These are used when the OS moves a process from memory to disk (to free up space), but it’s not dead.<\/p>\n\u00a0Process States in Operating Systems:<\/strong><\/h3>\n
