The most basic and smallest logical unit of information is a bit. A bit represents a binary value of either 0 or 1, and is the building block of all digital data.
Input Unit-such as a mouse, keyboard, image scanners, and reading from storage devices.
ARITHMETIC AND LOGICAL UNIT Anand bhat(mca@kiit-870024)
The unit that performs the arithmetic and logical operations within the processor is called the Arithmetic Logic Unit (ALU).
Arithmetic logic unit
A logical unit of data is a virtual representation of data while a physical unit of data is the actual storage of data on a physical device. The logical unit of data is how data is organized and manipulated from a software perspective, while the physical unit of data is how data is stored on hardware such as disks or memory.
The CPU (Central Processing Unit) has an ALU (Arithmetic and Logical unit) for performing logic based and mathematical commands within the computer.
The Arithmetic Logic Unit (ALU) is the heart of a CPU. This is what allows the computer to add, subtract, and to perform basic logical operations.
- An MMU (memory management unit) generates physical address. - A CPU (central processing unit) generates a logical address.
