Processing speed: hertz (Hz); MHz, GHz for Tech+
Short answer
Processing speed: hertz (Hz); MHz, GHz. Computing involves various units of measure for data and speed: - Bit (b): The smallest unit of digital information, representing a 0 or 1. Network speeds are measured in bits per second (bps). 8 bits = 1 byte. - Byte (B): A byte consists of 8 bits and is a basic unit of storage. File sizes use prefixes: KB, MB, GB, TB, PB. - Kilobyte (KB): Approximately 1,024 bytes. Similarly, Megabyte (MB) is ~1,024 KB, Gigabyte (GB) ~1,024 MB, Terabyte (TB) ~1,024 GB. - Throughput: Measured in bits per second: bps, Kbps (1,000 bps), Mbps (1,000,000 bps), Gbps (1,000,000,000 bps).

Concept 3
How to recognize it on Tech+
On FC0-U71, stay at beginner IT depth: identify when the question is asking about Processing speed: hertz (Hz); MHz, GHz, then choose the basic concept or support action that matches the situation. Do not jump into advanced vendor administration unless the prompt clearly gives that scope.
