A processor is anintegrated circuitthat performs mathematical calculations and logical operations. In older computer systems, thecentral processing unit(CPU) was solely responsible for executing all computations. Today’s computers typically have multiple types of processors that are optimized for different ...
What is a logical partition (LPAR)? A logical partition (LPAR) is a subset of a computer'sprocessor,memoryandI/Oresources that behaves much like a physical server. A computer can host multiple LPARs, each one running independently of the other. The LPAR has its own operating system (OS),...
Typically, the ALU has direct input and output access to the processor controller, main memory (random access memory orRAMin a personal computer) andinput/outputdevices. Inputs and outputs flow along an electronic path that is called abus. The input consists of an instruction word, sometimes cal...

Virtual processor/vCPU vCPU is time dependent entity. A virtual processor is more likely the amount of processing time spent on the CPU. If we use technical terminology; Virtual processors are mapped to available logical processors in the physical computer and are scheduled by the Hypervisor softwar...
operations and logical operations. Its math functionality is based on four types of operations (addition, subtraction, multiplication and division). Logical operations typically involve some type of comparison (such as of letters, numbers or special characters) that’s tied to a particular computer ...
What is hyper-threading in an Intel® processor? Hyper-threading in an Intel® processor is a technology that allows each core to execute multiple threads simultaneously, effectively doubling the number of logical cores. What is Turbo Boost in an Intel® processor?
CPU stands for the central processing unit. It's an electronic circuitry that performs arithmetical, logical, controlling, and input/output operations given by a computer program running on that computer. Alternatively referred to as a processor, central processor, or microprocessor, the CPU is the...
The reverse would be true in a memory chip, for example, where the memory controller was integrated into the memory chip. While modern designs don’t do this, it would be possible. In that case, the controller’s processing power is there to optimize the memory chip. It would still be ...
The Central Processing Unit (CPU) is the main component in a computing device responsible for executing instructions and performing calculations. Often described as the "brain" of the computer, the CPU handles several critical tasks:Instruction Execution: The CPU processes instructions from software ...
