Which term refers to the data stored in computer memory on which the processor applies the program instructions?

Cache memory is a small unit of ultrafast memory built into the processor that stores frequently or recently accessed program instructions and data. The primary difference is that registers store results of instructions from the CPU, whereas cache memory stores program instructions.

What is the term for the memory a computer uses to run programs?

RAM. The most common computer memory which can be used by programs to perform necessary tasks while the computer is on. The two main forms of modern RAM are static RAM (SRAM) and dynamic RAM (DRAM).

Where is memory stored in computer?

RAM stands for Random Access Memory. Physically, it is a series of chips in your computer. When your computer is turned on, it loads data into RAM. Programs that are currently running, and open files, are stored in RAM; anything you are using is running in RAM somewhere.

What type of data is stored in RAM?

RAM is used to hold data and instructions that are currently in use. In a modern PC, RAM is used to hold the operating system and any open documents and programs that are running. RAM can be read from and written to.

Where are the instructions stored in a computer?

In the Von Neumann architecture used by most computers memory locations are used to store both program instructions and data. The CPU cannot therefore distinguish between instructions and data just by reading the bit pattern stored at a memory address. The CPU program counter should therefore always contain the memory location of an instruction.

What kind of instruction code does a computer have?

A basic computer has three instruction code formats which are: Memory – reference instruction Register – reference instruction Input-Output instruction

How is an input-output instruction recognized in a computer?

Just like the Register-reference instruction, an Input-Output instruction does not need a reference to memory and is recognized by the operation code 111 with a 1 in the leftmost bit of the instruction. The remaining 12 bits are used to specify the type of the input-output operation or test performed.

How many bits are used in a memory reference instruction?

In Memory-reference instruction, 12 bits of memory is used to specify an address and one bit to specify the addressing mode ‘I’. Register – reference instruction The Register-reference instructions are represented by the Opcode 111 with a 0 in the leftmost bit (bit 15) of the instruction.
