Which unit of computer helps in communication between memory and arithmetic logic?

Which unit of computer helps in communication between memory and arithmetic logic?

The control unit must communicate with both the arithmetic/logic unit and memory. The arithmetic/logic unit (ALU) contains the electronic circuitry that executes all arithmetic and logical operations.

What is communication between processor and memory?

CPU of the computer system communicates with the memory and the I/O devices in order to transfer data between them. However the method of communication of the CPU with memory and I/O devices in different. The CPU may communicate with the memory either directly or through the Cache memory.

Which unit of computer helps in communication?

A classic example of a communication device is a computer modem, which converts a computer’s digital information to an analog signal for transmission over a telephone line. Similarly, a modem receives analog signals, and converts them to digital, for processing by the computer.

How does the CU and ALU work together?

CU decodes instruction, tells ALU the type of operation ALU need to perform and stores the input in Temporary registers by turning on the set wire. ALU operates the instruction. CU turns on the set wire of Accumulator and instructs ALU to store the immediate result in Accumulator (A Register).

What does ALU which carries arithmetic and logic operations process?

An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Most of the operations of a CPU are performed by one or more ALUs, which load data from input registers.

What is the responsibility of the arithmetic and logical unit in the CPU of a computer?

What is memory communication?

Shared Memory Communications (SMC) enables two SMC capable peers to communicate by using memory buffers that each peer allocates for the partner’s use. There are two types of Shared Memory Communications: Shared Memory Communications over Remote Direct Memory Access (SMC-R)

How does microprocessor communicate with memory and input device?

One communicates with a microcomputer via the I/O devices interfaced to it. Interfaces provide all input and output transfers between the microcomputer and peripherals by using an I/O bus. An I/O bus carries three types of signals: device address, data, and command. A microprocessor uses an I/O bus when it executes …

What is an electronic communication device?

An electronic communication device refers to a wireless telephone, personal digital assistant, or a portable or mobile computer that’s used for the purpose of composing, reading, or sending an electronic message.

What is communication technology in computer?

Communications technology, also known as information technology, refers to all equipment and programs that are used to process and communicate information. Professionals in the communication technology field specialize in the development, installation, and service of these hardware and software systems.

What is the function of the ALU and CU in a CPU?

Learn about this topic in these articles: 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. The control unit fetches data and instructions from memory and…

How do the ALU and accumulator work together in the CPU?

The accumulator can hold one of the two operands during any ALU operation. If we want to add two bytes together, this would just be an example here; one byte would go to the accumulator, and the other in memory or general purpose register. When executed the two numbers serve as the input to the ALU.

How are inputs and outputs transmitted through the main memory?

All inputs and outputs are transmitted through the main memory. This unit controls the operations of all parts of the computer but does not carry out any actual data processing operations. It is responsible for controlling the transfer of data and instructions among other units of a computer.

What is the function of Alu in computer architecture?

– It helps in communication between the memory and the arithmetic logical unit. – It also aids in the loading of data and instructions residing in the secondary memory to the main memory as required. The characteristics of the ALU are as follows: – The ALU is responsible for performing all logical and arithmetic operations.

What is the relationship between memory and the central processing unit?

Although closely associated with the central processing unit, memory is separate from it. Memory stores program instructions or data for only as long as the program they pertain to is in operation. Keeping these items in memory when the program is not running is not feasible for three reasons:

What is the function of memory unit?

It is also known as an internal storage unit or the main memory or the primary storage or Random Access Memory (RAM). Its size affects speed, power, and capability. Primary memory and secondary memory are two types of memories in the computer. Functions of the memory unit are −
