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

Expansions bus lines connect the CPU with expansion slots and peripheral devices.

In a computer,logical operations = comparisons.

The CPU follows the instructions of the motherboard's hardware in order to manipulate data into information.

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

Specialized expansion ports include MIDI ports for connecting amplifiers,digital keyboards,and the like and HDMI ports for connecting game consoles and DVD players.

The tiny piece of silicon that houses millions of microminiature electronic circuits is called a __________.

_________ language is the specific binary programming language built into a computer's CPU that the computer runs directly; the CPU can run only this code.

RAM is primary storage and is volatile.

The motherboard is also called the ________ board.

__________ drives have no moving parts and thus are less likely to break down than hard-disk drives are.

The CPU consists of three parts: the control unit,the ALU unit,and RAM.

High-speed storage areas that temporarily store data during processing and enhance the main processor's performance are called __________.

Unicode uses 2 bytes for each character,rather than 1 byte; ASCII uses 1 byte.

Most microcomputers use processors made by Intel or Advanced Micro Devices.

Which port,along with a special card and cables,supports the connection of microcomputers,modems,and printers in a local area network (LAN)?

________ are tiny electronic devices that act as on / off switches that process the on / off (1 / 0)bits used to represent data.

Regarding a ROM chip,"read-only" means that the CPU can retrieve programs (such as BIOS)from the ROM chip but cannot modify or add to those programs.

Millions of electronic components can be placed on a tiny piece of silicon called a __________.

Microcomputers' secondary storage capacity is measured mostly in megabytes.

A(n)__________ happens when the surface of the read / write head or particles on its surface come into contact with the surface of the hard disk platter.
