What action is taken by CPU after reset to execute first instruction of program?
The fetch-execute cycle.
Which component executes program instructions?
The CPU executes program instructions.
What is the function of the control unit in the CPU?
The control unit provides the timing and control signal to all operations of microcomputer. It control the flow of data between microprocessor and memory and peripherals.
What is another name for the processor chip?
Another name for the processor chip is the central processing unit (CPU). It is the core component of a computer system responsible for carrying out instructions to execute programs and perform calculations.
What is a CPU cycle?
The sequence of steps that a CPU performs.Also known as fetch-decode-execute cycle.
Who execute a program?
Anobody who uses it is said to "execute" or "run" the program.Anobody who uses it is said to "execute" or "run" the program.Anobody who uses it is said to "execute" or "run" the program.Anobody who uses it is said to "execute" or "run" the program.
Is CPU a program?
yes cpu is a program which is used to run moniter
How many instructions are executed by 1khz CPU?
A 1kHz CPU will execute 1000 cycles per second.
Why contents of a program counter change?
The PC (program counter) is a CPU memory variable, commonly called a "register," that the CPU uses to track where the current executing instruction is located in memory, or on some CPUs, where the next instruction to execute is. Without a PC, the CPU would not know where the code it is currently executing is stored, and thus would not be able to run programs.
What is the function of the central processing unit?
Its main function is to execute instructions stored in a memory, which allows system to perform various tasks. the cpu retrives instruction from the memory, decodes them and then executes them. this process is known as the fetch decode execute cycle. The cpu is responsible for performing the majority of the calculations and logical operations as required by a computer. it also manages the systems memory, input/output devices and communication with other devices in the system. additionally the cpu also acts as the control center that cordinates and synchronize the activities of other components in the system. in summary the main function of a cpu is to execute instruction of the computer program. in summary the main function of cpu is to execute instruction of the computer program which in turn allows the system to perform various tasks.
What is the term for a CPU's complete set of commands?
The entire set of instuctions that a CPU can execute is known as the CPU INSTUCTION SET.
What is a multi program system?
A group of jobs that are ready to be executed is called job pool. Since there is more than one job that can be executed, it is possible for the operating system to make a decision about which job to execute next. That decision keeps CPU utilization as high as possible. In general, it is not possible for a single user to keep CPU or I/O devices busy at all times. Multiprogramming allows the system .to increase CPU utilization by ensuring that the CPU always has a job to execute. The CPU has a pool of jobs. When the currently executing job has to wait (if it is performing some I/O), it is removed from the CPU- Another job is selected and the CPU now executes it. This process ensures that CPU is always executing a job if there is a job to execute. In a non-multiprogrammed system, if a job had to wait for an I/O operation, CPU would also have to wait until I/O was finished. Hammad Ali
