CPU clock speeds of a personal computer range between ________.

CPU clock speeds of a personal computer range between ________.

• A. 0.5 to 1 GHz
• B. 2 to 4 GHz
• C. 10 to 20 GHz
• D. 1 to 2 GHz

Answer: (B)

Clock speed tells you how many cycles per second a CPU can perform, measured in gigahertz. For most personal computers today, the typical baseline for mainstream CPUs sits in the low-to-mid GHz range. The option that matches this common baseline is 2 to 4 GHz, which reflects the standard operating speeds of many modern desktop CPUs. Speeds like 0.5 to 1 GHz are generally too slow for typical PC tasks, and 10 to 20 GHz isn’t practical for consumer CPUs due to power and heat limits. While some systems may run around 1 to 2 GHz or boost higher temporarily, the most representative broad range for modern PCs is 2 to 4 GHz.
