What part of the computer carries out arithmetic operations?


Which part of the computer calculates the results arithmetic operations such as additions or subtractions?

3.1. Arithmetic and Logic Operations. The ALU is the core of the computer – it performs arithmetic and logic operations on data that not only realize the goals of various applications (e.g., scientific and engineering programs), but also manipulate addresses (e.g., pointer arithmetic).

Which is responsible for performing arithmetic?

Arithmetic and logic unit is responsible for performing all the arithmetic computations such as addition, subtraction, division, multiplication and exponentiation. In addition to this it also performs logical operations involving comparisons among variables and data items. Was this answer helpful?

What is the name of the storage locations where values can be stored while arithmetic and OR logic operations are performed using these values?

The accumulator is used to hold the result of operations performed by the arithmetic and logic unit. The flag register is specially designed to contain all the appropriate 1-bit status flags, which are changed as a result of operations involving the arithmetic and logic unit.

What are the types of ALU?

An ALU consists of three types of functional parts: stor- age registers, operations logic, and sequencing logic, as shown in Fig. 1.

What is meant by main memory?

Main memory is the primary, internal workspace in the computer, commonly known as RAM (random access memory).

What are two main memory examples?

Primary storage

  • read only memory (ROM)
  • random access memory (RAM)
  • flash memory.
  • cache memory.

What is an example of the main memory?

An example of the main memory is where programs and data are kept. Main memory is the primary, internal workspace in the computer, commonly known as RAM (random access memory). Specifications such as 4GB, 8GB, 12GB and 16GB almost always refer to the capacity of RAM.

What is the main memory used for?

The main memory acts as the central storage unit in a computer system. It is a relatively large and fast memory which is used to store programs and data during the run time operations. The primary technology used for the main memory is based on semiconductor integrated circuits.

Is ROM main memory?

Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory. It is also called read-write memory or the main memory or the primary memory.

What is another name for main memory?

Answer: Main memory is sometimes called RAM. RAM stands for Random Access Memory.

What are the main parts of a memory?

The three main stages of memory are encoding, storage, and retrieval.

What are the 5 types of memory?

What are the different types of memory?

  • Types.
  • Sensory memory.
  • Short-term memory.
  • Working memory.
  • Long-term memory.
  • Capacity.
  • Improving memory.
  • Summary.

What are the 4 types of memory?

4 Types of Memory: Sensory, Short-Term, Working & Long-Term.

What are the 2 types of computer memory?

There are basically two kinds of internal memory: ROM and RAM. ROM stands for read-only memory.

What is the types of computer memory?

Types of computer memory

  • Cache memory. This temporary storage area, known as a cache, is more readily available to the processor than the computer’s main memory source.
  • RAM.
  • Dynamic RAM.
  • Static RAM.
  • Double Data Rate SDRAM.
  • Double Data Rate 4 Synchronous Dynamic RAM.
  • Rambus Dynamic RAM.
  • Read-only memory.

What is RAM and ROM with example?

RAM and ROM are both types of computer memory. RAM is used to store computer programs and data that CPU needs in real time. RAM data is volatile and is erased once computer is switched off. ROM have prerecorded data and it is used to boot computer. ROM stands for Read Only Memory.

What is computer block diagram?

A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. They are heavily used in engineering in hardware design, electronic design, software design, and process flow diagrams.

What is digital computer and block diagram?

A digital computer is considered to be a calculating device that can perform arithmetic operations at enormous speed. It is defined as a device that operates upon information/data.

How do you create a block diagram?

Block Diagram: Best Practices

  1. Identify the system. Determine the system to be illustrated.
  2. Create and label the diagram. Add a symbol for each component of the system, connecting them with arrows to indicate flow.
  3. Indicate input and output.
  4. Verify accuracy.

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 are the 5 parts of CPU?

The CPU is composed of five basic components: RAM, registers, buses, the ALU, and the Control Unit. Each of these components are pictured in the diagram below.
