66. (p. 156-158)The four types of system units are: tablet PC system unit, desktop system unit, notebook system unit, and PDA system unit. The desktop system unit can be placed horizontally (desktop) or vertically (tower). All input devices are located outside the system unit. The notebook system unit is portable and contains some integrated input devices, like a pointer and keyboard. Tablet PC system units are similar to notebooks, but are designed to use a stylus as the primary input device. The PDA system unit is very small (palm sized) and contains the entire computer system.

67. (p. 158)The three binary coding systems are ASCII, EBCDIC, and Unicode. ASCII is the most widely used system. EBCDIC was developed by IBM for use in large computers. Both of these systems use 8 bits per byte. Unicode was developed with funding from several large software companies. It uses 16 bits per byte to facilitate the storage of complex international alphabets.

68. (p. 162)A microcomputer has a single CPU which does not allow the computer to process heavy tasks. But with the help of a dual-core chip, even a microcomputer can run all the complex programs that only large computers could do. This is done through parallel processing.

69. (p. 162)Parallel processing is the simultaneous use of more than one CPU to run a program that allows faster execution and improved performance.

70. (p. 162-163)A smart card is essentially a plastic card the size of a regular credit card that has an embedded chip. It can store 80 times the information stored on the magnetic strip of a regular credit card. It is used for identification, providing access to a network, securing cellular phones, securing set-top boxes on televisions, storing medical files, personal records etc.

71. (p. 163-164)Flash RAM or flash memory chips can retain data even if power is disrupted. This type of RAM is the most expensive and used primarily for special applications such as for digital cell telephones, digital video cameras, and portable computers. It is different from other types of RAM because it is considered as non-volatile RAM.

72. (p. 166)While both allow you to connect to other computers, they work in different ways. A modem translates an audio signal to connect you via the telephone system. An NIC is used when this translation is not needed, such as a network.

73. (p. 170)Industry standard architecture (ISA), Peripheral component interconnect (PCI), Accelerated graphics port (AGP), Universal serial bus (USB), and FireWire buses (HPSB).

74. (p. 170)A serial port can only send one data bit at a time and is very good for sending data over a long distance. Parallel ports can send 8 bits at a time and are primarily used to connect printers.

75. (p. 171)An IrDA transmits infrared signals. Using this, we can transfer data from one device to another without any cables. For example, if both your desktop computer and printer have IrDA ports, you can simply put your computer near the printer and take printouts without needing to connect the two with a cable. The only thing is the two machines need is to be near each other.
