Understanding Processes and Threads in Operating Systems

Difference Between Threads and Processes

• The concept of a thread is introduced as a way to divide a process into multiple tasks that can be executed simultaneously, enhancing speed by utilizing multiple processors.

• Two categories of threads are discussed: LT (Lightweight Thread) which operates at the user level, and KMT (Kernel Managed Thread) which operates at the kernel level.

• LT threads are scheduled by programmers using algorithms, while KMT threads are managed by the operating system but may operate slower due to context switching requirements.

Definition and Characteristics of a Process

• A process is defined as an executable program running concurrently with other processes in a multitasking environment, such as web browsers or database systems.

• Unlike threads, processes are separate modules that cannot share memory directly; they require inter-process communication for resource sharing.
