A thread in a CPU is a sequence of instructions that the CPU can execute independently from other threads. Each thread has its own program counter, stack pointer, and set of registers. The CPU switches between threads to give the appearance of running multiple tasks simultaneously.

A process is a program in execution,it needs resources like CPU time,memory,files and i\o devices to accomplish its task. Threads are lightweight process
the 1.5 dual core can handle 2 threads at the same time and 3.0 single core can only handle 1 thread both of them switch threads rapidly if you have CPU-z you will find that the only difference in number of threads (the number of cores in single core is 2) short answer : the dual core is faster in multitasks the single core is faster in single task (like most of games)
A CPU is a Processor. (central processing unit or microprocessor), a CPU alias Processor can have multiple Cores which are basically processors but they are referred to as Cores.
In 8086 pipeline concept was introduced bcoz in 8086 we started using a buffer space which fetches the instruction at the same time when CPU processes
Pre-fetch - a component of the pipeline interfaces with the MCC (Memory Controller Chip) to get lines of code into the CPU
Central Processing Unit, CPU
A 4p server has 4 CPU socket in one motherboard; i.e. 4 physical CPU's(not just cores or threads) on one motherboard. A 2p server has dual CPU.
Context switching between kernel threads typically requires saving the value of the CPU registers from the thread being switched out and restoring the CPU registers of the new thread being scheduled.
Context switching is the process of saving the state of a process or thread, and then restoring the state of another process or thread for execution. Context switching enables multitasking by allowing multiple processes or threads to share a single CPU. It involves saving and restoring CPU registers, program counter, and stack pointers.
