Study Notes
Computer System Components
- The Central Processing Unit (CPU) is responsible for controlling the operation and performing the data processing functions.
- The CPU is also the component that performs the data processing functions and controls the operation of the computer.
Memory
- Volatile memory loses its contents when the computer is shut down.
- The contents of main memory that are lost when the computer is shut down are referred to as volatile memory.
Operating System
- The feature of the operating system that allows it to exploit the hardware resources of one or more processors is multiprocessing.
Input/Output (I/O) Components
- The component that moves data between the computer and external environments, such as storage and I/O devices, is the Input/Output (I/O) component.
Bus
- The main function of the System Bus in a computer is to move data between the computer and external environments.
Microprocessors
- The microprocessor that revolutionized desktop and handheld computing by integrating the processor on a single chip is the Microprocessor.
- System on a Chip (SoC) is the primary component in modern handheld devices, integrating the processor on a single chip.
Co-Processors
- The primary purpose of Graphical Processing Units (GPUs) in computing is to accelerate graphics processing.
- Digital Signal Processors (DSPs) were traditionally embedded in devices such as sound cards and modems.
- The primary purpose of System on a Chip (SoC) in modern handheld devices is to integrate the processor, memory, and input/output functions on a single chip.
Instruction Execution
- During the Fetch stage of instruction execution in a computer processor, the processor retrieves an instruction from memory.
- The Instruction Register (IR) holds the current instruction being executed by the processor.
- Interrupts alter the normal sequencing of a computer processor by interrupting the current instruction and executing a new one.
- An arithmetic overflow falls under the class of synchronous interrupts.
