Computer Components and Functions

ALU stands for Arithmetic Logic Unit, responsible for performing arithmetic and logical operations within a computer.
The component that stores data in a computer is known as memory, which may include various types such as RAM and hard drives.
The Control Unit coordinates and manages the operations of the computer, directing data flow and instructing other components on what tasks to perform.
System Interconnection, also known as buses, provides pathways for data communication between different components of a computer, ensuring efficient data transfer.
The hierarchical nature of complex systems is essential for organizing components and facilitating systematic communication and operation across various levels.
The function concerned with how components relate to one another is known as system architecture, which outlines the organization and interaction of components.
Input/Output (I/O) function involves receiving data from devices such as keyboards or interfaces, or sending data to output devices like monitors and printers.
The function that manages resource allocation and controls the performance of a computer's functional parts is known as the operating system.
The Memory Buffer Register (MBR) contains data that is being transferred to or from memory, acting as a buffer to match the data flow rate between the CPU and other memory areas.
The Instruction Register (IR) holds the current instruction being executed by the CPU, ensuring that the processor is aware of what operation to perform next.
The main function of the Program Counter (PC) is to keep track of the address of the next instruction that is to be executed, facilitating the sequential execution of instructions.
The purpose of the Accumulator (AC) is to hold intermediate results of arithmetic and logical operations, serving as a temporary storage location during processing.
