A central processing unit (CPU)
is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.
What carries out instructions to operate computer?
The central processing unit, or the processor
, interprets and carries out the basic instructions that operate a computer.
Who carry out the instructions in a computer program?
The processor, also called a CPU (central processing unit)
, is the electronic component that interprets and carries out the basic instructions that operate the computer. Memory consists of electronic components that store instructions waiting to be executed and data needed by those instructions (Figure 2.2).
What is an instruction in a computer program?
An instruction is
an order given to a computer processor by a computer program
. … In assembler language, a macro instruction is one that, during processing by the assembler program, expands to become multiple instructions (based on a previously coded macro definition).
Where are instructions stored in a computer?
Instructions are stored
in memory
and the contents of the PC register are used as the starting address from where the next to be executed instruction is read. Because the length of an 68k instruction is bytes can vary decoding and reading the instruction from memory (steps 1 and 2) is an iterative process.
Is a way of giving computers instructions about what they should do next?
Computer programming
is a way of giving computers instructions about what they should do next. These instructions are known as code, and computer programmers write code to solve problems or perform a task.
What are the 3 types of software?
As discussed the software is a program, script which executes on the computer system. And as we discussed there are broadly three types of software i.e.
system software, application software, and programming language software
. Each type of software has its function and runs on the computer system.
What is CPU explain with diagram?
A central processing unit (CPU) is the
electronic circuitry
within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.
What is RAM and ROM in computer?
RAM, which stands for random access memory
, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer. Find out more about RAM.
Which is the fastest and most expensive computer?
The supercomputer
is the fastest and the most expensive computer. The supercomputer is a device that runs at or above the maximum peak operating rate for software.
What are the different types of instructions?
- Arithmetic Instructions.
- Branch Instructions.
- Data Transfer Instructions.
- Logic Instructions.
- Bit-oriented Instructions.
Which hardware is used to type a text into the computer?
Keyboards
.
A keyboard
is a human interface device which is represented as a layout of buttons. Each button, or key, can be used to either input a linguistic character to a computer, or to call upon a particular function of the computer. They act as the main text entry interface for most users.
What is instruction with example?
The definition of instruction is the act of educating, giving the steps that must be followed or an order. An example of instruction is
someone giving another person detailed directions to the library
. noun.
What type of device is CPU?
The CPU (Central Processing Unit) is the
part of a computer system
that is commonly referred to as the “brains” of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program .
What is the program counter in a computer?
A program counter (PC) is
a CPU register in the computer processor
which has the address of the next instruction to be executed from memory. It is a digital counter needed for faster execution of tasks as well as for tracking the current execution point.
What is Ram in memory?
Random access memory
(RAM) is a computer’s short-term memory, which it uses to handle all active tasks and apps.
