What is a CPU (Central Processing Unit) do?
CPU stands for Central Processing Unit full form itself tells that all the input and processed here CPU process the data which is sent from input processes.
How much does a CPU (central processing unit) and server weigh on average?
The typical 32 bit or 64 bit CPU weighs a couple of ounces. (A CPU is an integrated circuit - it plugs into a socket on the motherboard.) A small 8 bit CPU can weigh well under an ounce (like the one in your cellphone). A server (or desktop - they're the same computer, just being used for different purposes) can weigh anywhere from a couple of pounds to many pounds, depending on the weight of the power supply, how many drives are in it, what other cards are in it, etc.
In between the control unit (CU) and the central processing unit (CPU), which of it is the brain and heart of a computer?
The CPU is just a larger assembly of which the CU is part of. It isn't seperate. If you want to call the CPU the brain, that must include the CU.If you want to think in terms of analogies, I've always thought of the CU as a puppetmaster of sorts, pulling imaginary strings to make his “puppets” (other CPU functional units) do its bidding.After all, things like ALUs have no instruction decoding capabilities: you give it data and it spits out a result. The only relevant control pins for it are command and enable wiring. These control signals are ultimately being generated by the control unit.
What is the function of central processing units in computers?
The CPU or Central Processing Unit is considered to be the “brain” of the computer, as a million other people have said on this feed. It is here where all data is processed, decisions are made, and actions are initiated.The CPU fulfills its job through a method called the Fetch-Decode-Execute cycle. To be more specific:The CPU first retrieves or (fetches) instructions that is stored in RAM (the program counter supplies it with the address of the instructions)It then interprets (decodes) the instructions and decides on the action it is about to performThe CPU finally carries out (executes) the instructions (the ALU is responsible for working with logical and mathematical operations)Just so you know, the CPU consists of the:Control unit (CU) - controls the activities of the CPU by sending out control signalsArithmetic and logic unit (ALU) - carries out arithmetic and logical operationsRegisters - memory stores within the CPU
How Does A CPU Work????????????????
A CPU is a collection of logic gates that operates on binary numbers. All they really do is add two binary numbers or subtract two binary numbers. This is done in a recursive process using these simple on-off logic gates. Physically the gates are implemented as transistors (which are just simple electrical switches). Once you have a device that can add and subtract you can do multiplication (which is repeated addition) and division (which is repeated subtraction). By creating a binary representation of decimal numbers (floating point) you can add, subtract, multiply and divide decimal numbers. Provided the CPU performs it's calculations fast enough you can now use it to control anything that can be represented as a mathematical problem. So a CPU is not intelligent per-se, nor does it perform particularly complex operations, in fact it's performing very simple, very repetitive operations, trillions of times to create the illusion of intelligence. Some of the control over how these simple operations are combined into more advanced operations are built into the construction of the CPU (the firmware) some is a type of software coding also built into the CPU (the microcode) and most of it is external programming (the software).
