Exam 4: The Components of the Unit System

The data bus transfers information about where the data should reside in memory, and the address bus transfers actual data.

The access time (speed) of memory has no affect on the overall performance of a computer.

Together, the four basic operations or a processor (fetching, decoding, executing, and storing) comprise a pipeline cycle.

A heat sink is a small ceramic or metal component with fins on its surface that absorbs and disperses heat produced by electrical components such as a processor.

Which of the following is a type of nonvolatile memory that can be erased electronically and rewritten, similar to EEPROM?

COGNITIVE ASSESSMENT What component converts the AC power in a wall plug to the DC power required by a computer?

Which of the following types of memory modules, such as that shown in the accompanying figure, positions the pins on opposite sides of the circuit board so they do not connect and thus form two sets of contacts?

Most of Intel's processor chips include vPro technology, which provides the capability to track computer hardware and software, diagnose and resolve computer problems, and secure computers from outside threats.

In the machine cycle, fetching refers to the process of translating instructions into signals the computer can execute.

COGNITIVE ASSESSMENT What are the three categories of items stored in computer memory?

COGNITIVE ASSESSMENT Which of the following identifies ROM chips that contain permanently written data, instructions, or information?

Which of the following is measured by the number of ticks per second?

A petabyte is equal to approximately 1 million bytes.

Which of the following is a device that plugs in a USB port on the system unit like the one in the accompanying figure and contains multiple USB ports in which users plug cables from USB devices?

COGNITIVE ASSESSMENT If you see eight numbers such as 01000101 grouped together and you are told these numbers represent the letter E, what is this combination of numbers called?

COGNITIVE ASSESSMENT What is the purpose of the system bus?

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

To help consumers evaluate various processors, Intel and AMD now use a(n) ____________________ scheme that more accurately reflects the processing speed of their chips.

COGNITIVE ASSESSMENT Where do RAM chips usually reside within a computer?

COGNITIVE ASSESSMENT What is memory access time?
