Study Notes
CPU and Memory
- The Central Processing Unit (CPU) consists of two main sections: the arithmetic/logic unit (ALU) and the control unit, which handle calculations and command execution, respectively.
- Flash memory is a type of non-volatile memory, retaining its content even when power is off, contrary to volatile memory which loses data without power.
- A memory chip is important, but it is not the most critical hardware component, as other factors contribute significantly to a computer's performance.
System Performance
- Monitoring CPU and RAM usage is essential for assessing a computer's operational efficiency, giving insights into performance bottlenecks.
- Updating an operating system is crucial to accommodate advancements in hardware compatibility and security enhancements.
Software Specifications
- Applications have defined system requirements, detailing necessary hardware specifications such as memory size and processor speed for optimal performance.
- A patch is a type of software designed to fix bugs or improve performance in existing applications without the need for a complete overhaul.
Processor Specifications
- The CPU is a pivotal component, integrating all electronic circuitry for processing tasks in personal computers.
- The type of processor directly impacts the speed at which a computer processes instructions from software.
Software Updates
- Major improvements to software, including new features or design changes, are released as upgrades, providing enhanced functionality to users.
