Processes and sessions are both important concepts in operating systems and computer networks.
A process is an instance of a program that is being executed by a computer's CPU. Each process has its own memory space and resources, and can interact with other processes through interprocess communication (IPC). Processes are managed by the operating system, which assigns resources and schedules their execution.
A session is a logical connection between two or more networked devices that allows them to communicate and exchange data. Sessions are established and managed by network protocols such as TCP/IP. A session can be thought of as a conversation between two devices, where each device sends and receives data. Sessions can be initiated and terminated by either device, and can be secured through encryption and authentication mechanisms.
In summary, processes are related to the execution of programs on a single computer, while sessions are related to the communication between multiple networked devices.
