Study Notes

Bytes and Data Measurement

A byte consists of eight bits, serving as a fundamental unit for data storage.
One byte typically represents a single character, such as a letter, number, or symbol.

Kilobytes

A kilobyte (KB) is a measurement unit for digital information, approximately equal to 1,000 bytes.

Megabytes

One megabyte (MB) equates to about one million bytes, commonly used to denote file sizes.

Gigabytes

A gigabyte (GB) corresponds to roughly one billion bytes, often used for larger data storage capacities.

CPU Processing Power

The processing power of a CPU is influenced by several factors:
- Speed of the processor, often measured in GHz.
- Number of cores, allowing multitasking and improved performance.
- Cache memory, which helps in speeding up data access.
- Front-Side Bus (FSB) speed, affecting data transfer rates between the CPU and memory.
