Answer 28

address

Question 29

ROM chips that contain permanently written data, instructions, or information

Answer 29

firmware

Question 30

determines the number of bits that the computer can transmit at one time

Answer 30

bus width

Question 31

What are the 2 components contained in the processor?

Answer 31

Processors contain a control unit and an arithmetic logic unit (ALU).

Question 32

Differentiate between arithmetic operations and comparison operations.

Answer 32

Arithmetic operations include basic calculations such as addition, subtraction, multiplication, and division. Comparison operations involve comparing one data item with another to determine whether the first item is greater than, equal to, or less than the other item.

Question 33

What is clock speed?

Answer 33

Clock speed is the pace of the system clock, that is measured by the number of ticks per second.

Question 34

How does clock speed affects the processor?

Answer 34

The faster the clock speed, the more instructions the processor can execute per second.

Question 35

What should you consider when selecting a processor?

Answer 35

(1) determine your needs (2) determine your current processor (3) research processor models

Question 36

What eCycling options are available?

Answer 36

(1) Wireless carriers and bog box retailers (2) not-for-profit organizations (3) secondary market (4) EPA

Question 37

List some reasons that home and businesses choose cloud computing.

Answer 37

(1) Accessibility (2) Cost Savings (3) Space Savings (4) Scalability

Question 38

In reference to cloud computing, describe the front end and back end.

Answer 38

Front end includes the hardware and software with which a user interacts to access the cloud. Back end consists of the servers and storage devices that manage and store the resources accessed by users.

Question 39

Differentiate between volatile and nonvolatile memory.

Answer 39

Volatile memory is temporary, because when the computer’s power is turned off it loses its contents. Nonvolatile memory is permanent, because it does not lose its contents when power is removed from the computer.

Question 40

Differentiate between RAM and ROM.

Answer 40

RAM (random access memory), also called main memory, consists of memory chips that can be read from and written to by the processor and other devices. ROM (read-only memory) refers to memory chips storing permanent data and instructions. RAM is volatile memory and ROM is nonvolatile.
