bus width
What are the 2 components contained in the processor?
Processors contain a control unit and an arithmetic logic unit (ALU).
Differentiate between arithmetic operations and comparison operations.
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.
What is clock speed?
Clock speed is the pace of the system clock, that is measured by the number of ticks per second.
How does clock speed affects the processor?
The faster the clock speed, the more instructions the processor can execute per second.
What should you consider when selecting a processor?
(1) determine your needs
(2) determine your current processor
(3) research processor models
What eCycling options are available?
(1) Wireless carriers and bog box retailers
(2) not-for-profit organizations
(3) secondary market
(4) EPA
List some reasons that home and businesses choose cloud computing.
(1) Accessibility
(2) Cost Savings
(3) Space Savings
(4) Scalability
In reference to cloud computing, describe the front end and back end.
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.
Differentiate between volatile and nonvolatile memory.
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.
Differentiate between RAM and ROM.
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.
