The processor (sometimes called the Central Processing Unit or CPU) is a piece of circuitry that is able to execute instructions. The instructions are given to the CPU in the form of electrical signals applied to the pins (wires) that lead to the inside of the processor. Generally, a positive electrical voltage represents the binary digit 1, and zero or perhaps negative voltage represents a 0. If we have lots of pins, we can specify a large variety of different patterns of 1's and 0's, each corresponding to a different instruction. (Data is also represented this way) So, in theory, you could buy a bunch of simple switches and hook them up to the processor, and specify instructions by hand. In practice, this would be silly, but this is essentially-how programming was done back in the 1950s with the first digital computers.
In a modern computer, the instructions are actually stored in memory (RAM) before being given to the processor. Usually, the get into the memory only after being read from your hard disk, which also stores patterns of 0's and 1's using magnetism. When you click on an application, you are reading the instructions from your hard disk into memory, from where the processor is able to access it and begin execution.
Lastly, your computer has a little bit of permanent or semi-permanent memory that contains special instructions for starting up when you turn it on and some other special situations. BIOS is an example of that.
Peripherals like sound cards and video cards are generally told what to do by the CPU, and don't give the CPU instructions.
Got that off a website...Yahoo answers XD... NOT MY WORDS!!! I do not take credit for it. Anyways i think its the processor...

What is instruction cycle with interrupts?
The instruction cycle is the basic operation cycle in a computer. This is what will take in data, process it and execute as required.
What is the difference in between instruction and information given to a computer?
Instruction refers to specific commands or code given to a computer to perform a task or operation, such as executing a program or carrying out a calculation. Information, on the other hand, refers to data provided to the computer for processing, storage, or retrieval, such as input data or output results. In essence, instructions tell the computer what to do, while information is the content or data on which the computer operates.
Computer and are capable in giving data information?
1. yes because computer and man are capable in giving data and information..
The process of saving data and instruction premanently is known as?
persistent storage
Computer process output information into input data?
No. Computer process (input) information into (output) data.
How does a personal computer process information?
In two basic stages: i) process - the computer needs, and is easily provided with, instructions about what to do with the data, and ii) data - readily accessible information that is accessed, operated upon, and results displayed by the instructions stored in the computer's instruction program.
The components that process data in a computer are where?
The components that process data are located in the system unit
What is a computer why it is known as data processor?
A computer is known as a data processor because that's what it does. Process data (programs)
Define input devices?
This is the process of entering data and programs in to the computer system. You should know that computer is an electronic machine like any other machine which takes as inputs raw data and performs some processing giving out processed data. Therefore, the input unit takes data from us to the computer in an organized manner for processing.
Is a process that allows the CPU to receive a single instruction and then execute it on multiple pieces of data rather than receiving the same instruction each time each piece of data is received?
"SIMD, which stands for 'single instruction, multiple data,' is a process that allows the CPU to receive a single instruction and then execute it on multiple pieces of data rather than receiving the same instruction each time each piece of data is received."(Pg. 434, A+ Guide to Managing and Maintaining Your PC)
What does process data mean in ict?
INPUT > PROCESS > OUTPUTProcessing data is when the data you inputed into the computer is changed to information and then outputed
What are multi vector and SIMD computers?
(Single instruction, Multiple Data) A process that allows the CPU to execute a single instruction simultaneously on multiple peices of data, rather than by repetitive looping.
