1.Programmed IO is the process of IO instruction written in computer program , where Interrupt Initiated IO is done by using interrupt and some special command. 2.The advantage of Interrupt Initiated IO is ,it is a time consuming process than Programmed IO. 3.In Programmed IO technique to transfer data,required constant motoring on peripheral by CPU,once data transfer is initiated, CPU have to wait for next transfer. In Interrupt Initiated IO once data transfer initiated ,CPU execute next program without wasting time and the interface keep monitoring the device. When the interface determines that the device is ready to transfer data, it generate an interrupt request,CPU stop the current task,execute the transferring process,and then return to the previous on-processing task. Show basic instructions that operate a computer. two or more separate processor cores. ◦ Control Unit: Component of the processor that directs and coordinates most of the operations in the computer. instruction or data item from memory. What is arithmetic logic unit in computer?function in digital computer …of a control unit, an arithmetic logic unit (ALU), a memory unit, and input/output (I/O) controllers. The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND. The memory stores the program’s instructions and data. What are the control unit and arithmetic logic unit components of a processor? The central processing unit (CPU) consists of six main components: control unit (CU) arithmetic logic unit (ALU) registers….Control unit
What are the four steps in the machine cycle? Four steps of the machine cycle
What is arithmetic and logic operations?An ALU performs basic arithmetic and logic operations. Examples of arithmetic operations are addition, subtraction, multiplication, and division. Examples of logic operations are comparisons of values such as NOT, AND, and OR. Operations can be accomplished by connecting multiple transistors. What are the three steps in a machine cycle?It is the most basic CPU operation, and modern CPUs are able to perform millions of machine cycles per second. The cycle consists of three standard steps: fetch, decode and execute. In some cases, store is also incorporated into the cycle. focusNode Didn't know it? Knew it?

The control unit directs and coordinates most of the operations in the computer. Terms in this set (26) The component of the processor that directs and coordinates most of the operations in the computer. Also called a CPU (central processing unit), is the electronic component that interprets and carries out the basic instructions that operate a computer. The Arithmetic Logic Unit (ALU) performs arithmetic, comparison and other operations. The arithmetic logic unit (ALU) performs the arithmetic and logical functions that are the work of the computer. |
