What are the resources required in a process execution in operating system?

In process execution within an operating system, the primary resources required include CPU time, memory (both RAM and cache), and I/O devices (such as disk drives and network interfaces). Additionally, processes require system resources such as process control blocks (PCBs) for tracking execution state and scheduling, as well as access to system calls for interacting with the OS. Effective management of these resources is crucial for maintaining system stability and performance.
