CPUs work on a cycle that is managed by the control unit and synchronized by the CPU clock. This cycle is called theCPU instruction cycle, and it consists of a series of fetch/decode/execute components. The instruction, which may contain static data or pointers to variable data, is fetched...

Before we dive into what a CPU does, let's discuss some basic computing concepts. Computers are made up of several components, including input/output devices (keyboard, mouse, etc.), memory (RAM), storage (hard drive/SSD) and processors. A processor is like a brain in your computer—it ...
Many microprocessors (in smartphones and desktop, laptop, server computers) have a memory management unit, translating logical addresses into physical RAM addresses, providingmemory protection and paging abilities, useful for virtual memory. Simpler processors,...
Circuit traces on the motherboard link parts of the CPU to other components of the system Equivalent to having a shared set of wires to which all components are connected Microchips communicate with each other using clock signals and electrical pulses ...
A process includes the following attributes and components:A virtual address space Priority class Loaded program modules Environment and configuration information At least one thread Although processes contain the program modules, context and environment, they are not directly scheduled to run on a...
Performance analysis is a four-step process:Define the scenario and the problem. Identify the components that are involved and the relevant time range. Create a model of what should have happened. Use the model to identify problems and investigate root causes.Define the Scenario and the Problem...
The following CPU components are also essential: Cache:Memory speed is a critical aspect of how CPUs run, and yet, ironically, the CPU does not actually access RAM. Instead, modern CPUs have one or multiple layers of cache that routinely handle such tasks (at speeds faster than RAM can ach...
CPU components Modern CPUs in electronic computers usually contain the following components: Control unit:Contains intensive circuitry that leads the computer system by issuing a system of electrical pulses and instructs the system to carry out high-level computer instructions. ...
