A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary processor in a given computer. [ 1 ] [ 2 ] Its electronic circuitry executes instructions of a computer program , such as arithmetic , logic, controlling, and input/output (I/O) operations.
PDP-11 CPU board. Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [1] [2]
The adult human brain weighs on average about 1.2–1.4 kg (2.6–3.1 lb) which is about 2% of the total body weight, [2] [3] with a volume of around 1260 cm 3 in men and 1130 cm 3 in women. [4] There is substantial individual variation, [ 4 ] with the standard reference range for men being 1,180–1,620 g (2.60–3.57 lb) [ 5 ] and for women ...
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
[2] [3] In the past, processors were constructed using multiple individual vacuum tubes, [4] [5] multiple individual transistors, [6] or multiple integrated circuits. The term is frequently used to refer to the central processing unit (CPU), the main processor in a system. [ 7 ]
