Exam 4: The Components of the System Unit

The cases of the system unit, sometimes called the ____, is made of metal or plastic and protects the internal electronic components from damage.

ROM chips called _________________________ contain permanently written data, instructions, or information that is recorded when the chip is manufactured.

Synchronous DRAM (SDRAM) chips are faster than DRAM chips because they ____.

_________________________ uses a continuous flow of fluid(s), such as water and glycol, in a process that transfers the heated fluid away from the processor.

A variation of the PROM chip, called a(n) ____ chip, allows a programmer to erase the microcode with an electrical signal.

Within the circuitry of a computer, each channel along which bits transfer, called a(n) _________________________, allows the various devices both inside and attached to the system unit to communicate with each other.

Current processors include advanced transfer cache, a type of ____ built directly on a processor chip.

Some applications draw on the idle time of home users' personal computers to achieve parallel processing.

Manufacturers and other retailers usually list a computer's memory in terms of its access time .

Explain what the motherboard is, and use the following terms in your answer: chip, integrated circuit, and transistor

A byte is uninformative because it provides only enough different combinations of 0s and 1s to represent 8 individual characters.

____ is the most widely used coding scheme used to represent data.

In the binary system, the digit 1 represents the electronic state of off (absence of an electronic charge).

The ____ processor(s) is/are ideal for workstations and low-end servers.

Most computers use flash memory to hold their startup instructions because it allows the computer easily to update its contents.

The combinations of 0s and 1s that represent characters are defined by patterns called a coding scheme.

L2 cache is slightly faster than L1 cache but has a much smaller capacity.

A(n) ____ processor is a chip with two or more separate processors.

A ____ equals approximately 1 billion bytes.

The processor interprets and executes a program's instructions while the program is in RAM.
