Exam 4: The Components of the System Unit

If a memory chip can store 100 KB, it can hold approximately 100,000 bytes.

Buses transfer bits from input devices to memory, from memory to the processor, from the processor to memory, and from memory to output or storage devices.

Female connectors have one or more exposed pins, like the end of an electrical cord that is plugged into the wall.

The electronic components and circuitry of the system unit, such as the processor and memory, usually are part of or are connected to a circuit board called the fatherboard.

A heat sink uses a continuous flow of fluid to transfer the heated fluid away from the processor to a radiator-type grill.

The _________________________ is the component of the processor that performs arithmetic, comparison, and other operations.

Instead of port, the term ____ sometimes is used to identify audio and video ports.

Two types of cache are memory cache and disk cache.

Some printers can connect to the system unit using a parallel port.

Figure 4-1 In the machine cycle steps illustrated in Figure 4-1, ____ is the process of carrying out commands.

Each byte resides temporarily in a location in memory, called a(n) ____.

The size of a bus, called the _________________________, determines the number of bits that the computer can transmit at one time.

____ memory does not lose its contents when power is removed from the computer.

A system unit with a MIDI port has the capability of recording sounds that have been created by a synthesizer and then processing the sounds (the data) to create new sounds.

The processor relies on a small quartz crystal circuit called the ____ clock to control the timing of all computer operations.

Dynamic RAM (DRAM) chips are faster and more reliable than any version of SRAM chips.

Manufacturers often identify cables by their connector types to assist users with purchasing a cable to connect to a peripheral.

Some computers use more than one processor chip.

The _________________________ is the component of the system unit that converts the wall outlet AC power into the DC power a computer requires.

Figure 4-2 With a type of memory module called a(n) _________________________, such as that shown in Figure 4-2, the pins on opposite sides of the circuit board do not connect and thus form two sets of contacts.
