Exam 4: Hardware: the Cpu and Storage: the Source of Computing Power

High-speed storage areas that temporarily store data during processing are called __________.

The computer determines what information in RAM is being used frequently and copies that information into cache,a special memory area built into the CPU that can be accessed quickly and thus speeds up processing.

Electrical data roadways through which bits are transmitted within the CPU and other components of the motherboard are called _________.

A tiny electrically operated switch that can turn on and off many millions of times per second is a microchip.

Data can be recorded on both sides of a hard disk's platters,which are sealed within a hard-drive unit.

Data on hard disks is recorded in concentric bands called ________.

In the computer world,what does "binary" mean?

Hard disks are optical disks.

Integrated circuits are electronic circuits formed on a single chip.

A computer processor handles bits in chunks called word size-for example,a 32-bit word size transfers data within each microprocessor chip in 32-bit,or 4-byte,chunks.A computer that uses 64-bit word size is faster than a 32-bit computer.

Buses transmit bits within the CPU and between the CPU and other components of the motherboard.The number of bits that the bus can handle at one time is the computer's word size.

The number of bits ("chunk")that the processor may process at any one time is called __________.

An opening in a computer tower used for the installation of equipment such as a hard drive is called a port.

Online storage services allow users to use Internet servers to back up data.

Data stored on CDs,DVDs,and flash memory sticks lasts basically forever.

Which of the following disks can be rewritten many times?

The Universal Serial Bus (USB)eliminates the need for cards in expansion slots on the motherboard.

Flash memory is a(n)________ technology.

The part of the CPU that interprets instructions and executes them is the control unit.

The number of registers in the ALU and the size of each help determine the power and speed of a CPU.
