Many computer chips will automatically throttle their performance to avoid overheating. Computers also typically have mechanisms for dissipating excessive heat, such as air or liquid coolers for the CPU and GPU and heatsinks for other components, such as the RAM. Computer cases are also often ventilated to help dissipate heat from the computer ...
The operating system maintains this table to keep track of which processes are waiting for which devices. One field in the table is the memory address of the process control block. Place all the characters to be sent to the device into a memory buffer. [65] Set the memory address of the memory buffer to a predetermined device register. [77]

The following outline is provided as an overview of and topical guide to computers: Computers – programmable machines designed to automatically carry out sequences of arithmetic or logical operations. The sequences of operations can be changed readily, allowing computers to solve more than one kind of problem.
Another such computer was the LEO III, first released in 1961. During batch processing, several different programs were loaded in the computer memory, and the first one began to run. When the first program reached an instruction waiting for a peripheral, the context of this program was stored away, and the second program in memory was given a ...
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.).
