Study Notes
Computer System Components
- The Arithmetic Logic Unit (ALU) performs arithmetic and logical operations in a computer system.
- The ALU is responsible for executing instructions that involve mathematical calculations and logical comparisons.
Hardware Components
- Computer hardware refers to the physical components of a computer system.
- Examples of computer hardware include the ALU, ROM (Read-Only Memory), and RAM (Random Access Memory).
Memory Components
- ROM is a type of non-volatile memory that stores data permanently, meaning it retains its contents even when the power is turned off.
- RAM is a type of volatile memory that stores data temporarily while the computer is running, and its contents are lost when the power is turned off.
- RAM's primary function is to provide a temporary storage space for data and program instructions while they are being executed.
Software Components
- Software refers to the intangible programs and operating systems that run on a computer system.
- The primary function of software is to provide instructions that a computer's hardware can execute to perform specific tasks.
- Software is responsible for controlling and interacting with the computer's hardware components.
