Chapter 1-3
1. A serial port transmits data in parallel and is most often used by an older printer.
2. When data and instructions are not being used, they must be kept in permanent storage, sometimes called primary storage.
3. Parallel ATA, sometimes called the EIDE (Enhanced IDE) standard or the IDE standard is slower than SATA.
4. A mother board can have more than one bus, each using a different protocol, speed data path size, and so on.
5. Some very basic instructions are stored on the motherboard- just enough to start the computer, use some simple hardware devices such as monitor and keyboard, and search for an operating system stored on a storage device such as hard drive or CD.
6. To perform a computing task, software uses hardware for four basic functions: _____.
input, processing, storage, and output
7. Most input/output devices communicate with components inside the computer case through a wireless connection or through cables attached to the case at a connection called a(n) ________.
8. A device that is not installed directly on the motherboard is called a(n) __________.
9. The _______ is a group of microchips on the motherboard that control the flow of data and instructions to and from the processor.
10. A(n) _________ is a set of rules and standards that any two entities use for communication.
1. The electrical requirements for motherboards change over time as new technologies make additional demands for power.
2. Micro ATX increases the total cost of a system by increasing the number of expansion slots.

2. Today's PC's have four or five buses, each with different speeds, access methods, and protocols.
3. PCIe is backward compatible.
4. The motherboard configuration stored in BIOS setup needs to be changed when a new floppy drive is installed.
