Threads in CPU are virtual components or codes that divide the physical core of a CPU into virtual multiple cores. A thread is a sequence of instructions given to the CPU by a program or application. The more threads a CPU can execute at once, the more tasks it can complete. Threading in a CPU is a technique that can increase the speed and efficiency of multitasking. It enables multiple threads of execution to run simultaneously on one or more cores in a single processor, allowing for quicker response times and more efficient use of resources. Modern processors support hyperthreading, a technology that allows one physical core to be divided into two virtual cores, thus allowing the CPU to work on multiple threads of execution simultaneously. AMD CPUs use simultaneous multithreading (SMT) to provide threads, while Intel CPUs use hyper-threading. Threads share the same resources as the core, and the number of threads a CPU can handle is limited by the physical space available on the chip. The more cores and threads a CPU has, the more independent tasks the processor can run concurrently.
