Arrival: This refers to the time at which a process arrives in the system or the time at which a task is introduced into the system.

Deadline: This is the time by which a process or task must be completed. It is often used in real-time systems where tasks have to be completed within a certain time frame.

Burst: This is the time required by a process to get executed on the CPU. It is also known as the execution time or CPU burst time.

Waiting: This is the amount of time a process has been waiting in the ready queue to be assigned to the CPU for execution.

Ready: This is a state of a process in the process lifecycle where the process is loaded into main memory and is awaiting execution.

Scheduling: This is the method by which work is assigned to resources that complete the work. In an operating system, it's the way processes are assigned to run on the available CPUs.

Completion Time: This is the time at which a process completes its execution. It is calculated from the time the process entered the system to the time it is fully executed.

Tardiness: This is the amount of time that a task is late by its deadline. It is calculated as the difference between the completion time and the deadline.

Laxity: Also known as slack time, it is the amount of time that you can delay a task without causing a delay to subsequent tasks. It is calculated as the difference between the task's deadline and its completion time.
