Binary is a base ______ system.

binary object code or machine code

Computer instruction form directly executable by a computer is the:

4 bytes long

Computer instructions are typically:

False

Computer memory is divided into bytes of 9 bits. T / F

False

Computer memory is divided into bytes of 9 bits. T/F

kilo, mega, giga, tera

From smallest to largest, the correct order of prefixes is:

False

Higher bandwidth usually means higher latency.

False

Higher bandwidth usually means higher latency. T/F

program counter

Holds address of next instruction to be executed:

16

How many digits are there in the hexadecimal system?

16

How many symbols can be represented with 4 bits?

data

In addition to fetching instructions, the Fetch and Execute cycle also fetches:

program counter

Keeps track of the next instruction to execute.

gigahertz

On the computer, one billion clock ticks per second is called:

true/false on/off black/white

One binary digit can be used to represent:

Compiler

Processes statements written in a high-level programming language and turns them into machine language

True

RGB, the name for a color encoding method, is an acronym for red, green, blue.T /F

Memory

Stores both program and data while the computer is running:

OCR

Technology that enables a computer to "read" printed characters

True

The ADD instruction adds the values, not the address numbers of the memory locations. T/F

True

The byte is the standard unit for computer memory. T/F

Hertz

The computer's clock speed is measured in:

ASCII

The eight-bit character set used on computers to represent letters, numbers and symbols:

FF0000, 00FF00, 0000FF

The hex codes that coorespond to the primary pixel colors of red, green, and blue are:

The context that the software interpretes them

The meaning of bits depends upon:

lossy

The method of image compression that allows some loss of the image information is called:

PC+2

The next instruction in a Fetch/Execute cycle is often at the memory address:

3) next instruction to be executed

The program counter keeps track of the:

fetch/execute

The series of instructions a computer cycles through:

Latency

The time it takes for information to be delivered:

6

To represent 50 unique characters, _______ bits must be combined.

False

Traditional hard drives are more efficient than solid state drives because there are no moving parts and they are typically smaller, last longer, and consume less energy T/F

the computer clock

What determines the rate the fetch and execute cycle is performed?

represent with digits (1's and 0's)

What does it mean to digitize information?

add values in 2040 and 2080 and put result in 2200

What does the following machine instruction do? ADD 2200, 2040, 2080

data and instructions

What is loaded in memory when a program is running:

Black

When all the RGB color settings are set to 0, the color displayed is:

Sampling rate

When digitizing sound, _________ plays a major role in the accuracy of the digital representation.

Speed

Which of the following characteristics of a computer depends on the number of Fetch/Execute cycles it performs per second?

1. cache memory, 2. main memory, 3. SSD 4. USB flash drives 5. magnetic tape

Which of the following lists storage in order from fastest to slowest?

decreased connectivity.

Which trend should not be associated with modern devices?

a binary object file or machine code

________ is a long list of words, more accurately, a long series of 0's and 1's that make up a computer program.
