Study Notes
Types of Volatile RAM
- SRAM (Static Random Access Memory) is a type of volatile RAM used for cache memory in CPUs.
- Flash Memory is non-volatile, while ROM (Read-Only Memory) and CD-ROM (Compact Disc Read-Only Memory) are types of permanent storage.
Energy-Efficient CPU
- ARM Cortex CPUs are designed for energy efficiency, making them commonly used in mobile devices due to low power consumption.
Multi-Core vs. Single-Core CPU
- Multi-core CPUs allow improved parallel processing and multitasking, enhancing overall performance compared to single-core CPUs.
Control Unit Functions
- The control unit in a CPU manages instruction execution, directing the operation of the processor and coordinating activities between the CPU and other components.
CPU Architecture in Mobile Devices
- ARM architecture is prevalent in smartphones and mobile devices due to its efficiency and performance balance.
Purpose of Primary Storage (RAM)
- The primary storage (RAM) provides fast data retrieval for active tasks, enabling the smooth operation of currently running applications.
Single-Tasking CPU
- A single-core CPU can only handle one task at a time, contrasting with multi-core and dual-core CPUs that can process multiple tasks simultaneously.
CPU Mathematical Operations
- The Arithmetic Logic Unit (ALU) within the CPU is responsible for handling mathematical and logical operations essential for computation.
Primary Function of a CPU
- The primary function of a CPU is to execute instructions and perform calculations, facilitating the operation of software applications.
Data in Primary Storage When Powered Off
- Data stored in primary storage (RAM) is permanently lost when the computer is powered off, as it does not retain information without power.
Types of Volatile RAM
- SRAM (Static Random Access Memory) is a type of volatile RAM used for cache memory in CPUs.
- Flash Memory is non-volatile, while ROM (Read-Only Memory) and CD-ROM (Compact Disc Read-Only Memory) are types of permanent storage.
