The part of the computer that fetches and decodes instructions is the Central Processing Unit (CPU), specifically within its control unit. The control unit retrieves instructions from memory, decodes them to understand what actions are required, and then sends signals to other components of the computer to execute those instructions. This process is fundamental to the operation of a computer, enabling it to perform tasks efficiently.

What is the part of a computer that gives directs nstructions?
The instruction unit (decodes and sends commands to alu of the cpu)
WHAT IS Instruction fetch?
Instruction fetch is the process by which the CPU retrieves instructions from memory in order to execute them. The CPU fetches instructions one at a time, and these instructions are then decoded and executed as part of the program being run. Efficient instruction fetching is important for the overall performance of a computer system.
What does it mean to say that a computer understands a program?
The only part of a program a computer understands is each instruction as it is presented to the instruction decoder. It understands the instruction by an intricately designed logic circuit and/or microprogram configured by a human computer hardware engineer. This engineer had to fully understand the instruction set of the machine to teach it to understand the instructions one at a time at runtime.
What is copnditional branch?
In programming, an instruction that directs the computer to another part of the program based on the results of a compare.
Which Part of the brain that controls intellectual functions and decodes information from the senses?
hypothalamus
What is prefetch queue in 8086?
In the context of the 8086 microprocessor, the prefetch queue is a 6-byte high-speed queue that stores the next instruction to be executed. This helps improve performance by fetching instructions in advance and storing them in the queue. When the CPU is ready to execute the next instruction, it can quickly access it from the prefetch queue without having to wait for the instruction to be fetched from memory.
How Microprocessors work?
A microprocessor is the main part of a computer. It is the engine of a computer that has been created on only one chip. It stores data, moves data from one memory location to another, communicates with other parts of the computer, can do computations, and is controlled by assembly language instructions, that it fetches from some memory.
When an instruction is read from the memory it is called?
When an instruction is read from memory, it is called "fetching." This process is part of the instruction cycle, where the Central Processing Unit (CPU) retrieves an instruction from memory to execute. Fetching is the initial step, followed by decoding and executing the instruction. This sequence is essential for the proper functioning of a computer's processing capabilities.
Name the part of the computer that stores all information and software?
The Hard Drive is the main storage unit in a normal, desktop computer. This is the only internal component in a standard computer that has information when the machine is turned off (all your saved files, the operating system (such as Windows), etc). There are other components (such as RAM, or Random Access Memory) that store data, but this usually serves a special purpose, or is only at run-time.
What part of speech is the word instruction?
Instruction is a noun.
In what ways can a computer process data?
The part of the computer that processes data is called the processor or processing unit. Older computers had a Central Processing Unit (CPU) . Modern machines often have more than one processing unit. The processor fetches and decodes the instructions that make up the program as well as doing the arithmetical operations.
What Part of a computer that plays music and data?
A computer can only produce sound if it contains the right hardware. These come in the forms of sound cards or sound chips. In most cases these devices only convert the sound data from digital to analogue signals - the computer itself reads the binary data and decodes it into a form understandable by humans.
