In computer architecture, instructions per cycle (IPC), commonly called instructions per clock, is one aspect of a processor's performance: the average number of instructions executed for each clock cycle. It is the multiplicative inverse of cycles per instruction. [1] [2] [3]
Therefore, a superscalar processor can be envisioned as having multiple parallel pipelines, each of which is processing instructions simultaneously from a single instruction thread. Most modern superscalar CPUs also have logic to reorder the instructions to try to avoid pipeline stalls and increase parallel execution.
In computer science, interprocess communication (IPC) is the sharing of data between running processes in a computer system. Mechanisms for IPC may be provided by an operating system . Applications which use IPC are often categorized as clients and servers , where the client requests data and the server responds to client requests. [ 1 ]

It takes five clock cycles to complete one instruction and thus the processor can issue subscalar performance (IPC = 0.2 < 1). A computer program is, in essence, a stream of instructions executed by a processor. Without instruction-level parallelism, a processor can only issue less than one instruction per clock cycle (IPC < 1).
A process with two threads of execution, running on one processor Program vs. Process vs. Thread Scheduling, Preemption, Context Switching. In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. [1]
They are a limited form of inter-process communication (IPC), typically used in Unix, Unix-like, and other POSIX-compliant operating systems. A signal is an asynchronous notification sent to a process or to a specific thread within the same process to notify it of an event.
The introduction states that IPC is "a set of techniques for the exchange of data between two or more threads in one or more processes" - this makes no sense to me. If it is inter-process then it should be "two or more processes" and not "two or more threads". As far as I know, *nix OS create a new process when you fork() - not just a new thread.
