True or False ____ 1. Most personal computers use Unicode, although Extended ASCII code is becoming increasingly popular. ____ 2. The prefix tera- means trillion. ____ 3. 100 MB is smaller than 100 Mb. ____ 4. The motherboard is a synonym for the main circuit board inside the system unit. ____ 5. A DIMM has three rows of pins that connect the IC circuitry to a circuit board. ____ 6. A DIMM is typically used for memory. ____ 7. A DIP is typically used for microprocessors. ____ 8. You can usually identify the microprocessor when looking inside a computer, as it is the only chip on the motherboard. ____ 9. Megahertz means a billion cycles per second. ____ 10. An 8-bit processor is faster than a 64-bit processor. ____ 11. You cannot add more L1 cache to your computer without replacing the microprocessor. ____ 12. AMD (Advanced Micro Devices) is Intel’s chief rival in the PC chip market. ____ 13. A microprocessor can operate at full efficiency only if all components in the computer can also handle the faster speeds. ____ 14. ROM is the “waiting room” for the computer’s processor. ____ 15. RAM is usually a single chip or small circuit board that plugs into the motherboard. ____ 16. Disk storage typically has less storage capacity than RAM. ____ 17. Too much dependence on virtual memory can have a negative effect on your computer's performance because getting data from a mechanical device is much slower than getting data from an electronic device. ____ 18. Whereas RAM is permanent and non-volatile, ROM is temporary and volatile. ____ 19. When you change the configuration of your computer system, the data in CMOS must be updated. ____ 20. An optical disk, such as a CD, is not susceptible to humidity, fingerprints, dust, magnets, or spilled soft drinks, and its useful life is estimated at more than 200 years. ____ 21. Random access, also called “direct access”, is the ability of a device to “jump” directly to the requested data. ____ 22. CD-R technology allows you to write data on a disk, and then change that data. ____ 23. Most CD drives can read CD-ROM, CD-R, CD-RW, and DVD. ____ 24. A trackball looks like the tip of an eraser embedded in the keyboard of a notebook computer. ____ 25. An ink jet printer has a nozzle-like print head that sprays ink onto paper to form characters and graphics.
