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

The most common port of microcomputers today is ________.

Integrate circuits use solid-state technology,whereby electrons travel through solid material called silicon.

Machine language is easy for people to understand.

The system clock,which controls how fast all the operations in a computer take place,uses fixed vibrations from a quartz crystal to deliver a steady stream of digital pulses or "ticks" to the main processor,which are called __________.

Usually built into the processor chip,__________ memory temporarily stores instructions and data that the processor is likely to use frequently and thus speeds up processing.

A smart card looks like a credit card,but it has a(n)_________ built into it.

One million cycles (ticks)of the system clock per second equal 1 __________.

One ________ equals about 768 pages of text. A. byte B. kilobyte C. megabyte D. gigabyte

A semiconductor is a material whose electrical properties are intermediate between a good conductor of electricity and a nonconductor of electricity.

Smart cards are plastic,laser-recordable,wallet-type cards used with an optical-card reader.

EBCDIC is the binary coding scheme developed for microcomputers.

In __________,atoms and molecules are used to create tiny machines for holding data or performing tasks.

In secondary storage technology,the __________ is used to transfer data between the computer and the disk.

The surface of a DVD-ROM contains microscopic pits,which represent the 0s and 1s of digital code that can be read by a laser.

A fixed disk is not portable.

Microcomputer chips designed to let the operating system divide the work of processing over more than one chip are called multicore processors.

In disk storage technology,the read / write head transfers data back and forth between the computer and the disk.

__________ is thought of as the primary workspace inside the computer.

The binary code widely used with microcomputers is EBCDIC.

A gigabyte is about 1 million bytes.
