Comp. Apps for Business Exam #1

Add value to each pixel

The white pixels are more modified than the dark pixels (or vice versa) to increase the amount of difference between white and dark

Adding 16 to each byte

Lossy compression schemes will discard data, losing bits of the original information. Lossless
Compression schemes make the full recovery of the original information possible.

Less difficult to write down and less lengthy sequence of bits to remember

The "higher" the ranking, the closer to the top of the list a page will be

Sound is picked up by a microphone. The electrical signal is fed into an analog-to-digital converter, which takes the continuous wave and samples it at regular intervals, outputting for each sample binary numbers. These numbers are compressed and stored in memory.

Placed thousands of transistors onto a single silicon chip; this paved the way for personal computers and modern electronic devices

Primary processor in a computer, its electric circuit executes of a computer program, such as arithmetic log, controlling, and input-output operations.

stores information such as data and programs for immediate use in the computer

Not directly accessed by the CPU, storage for non-critical data that doesn't need to be accessed as frequently

Programmers can use the software without understanding how the programs work, allowing them to builkd off the work of other programmers who have previously contributed to these layers

Input, Output Information, Store, Process

Information that has continuous values (ex: sound waves)

Uses distinct values, usually binary (uses 0s and 1s)

A digitization guideline stating that the sample frequency should be twice as high as the highest frequency of the signal

Point to point communication means the channel is shared between two devices

Multicast is a method of group communication where the sender sends data to multiple receivers or nodes present in the network simultaneously, multiple point-to-point communication (to specific groups)

In this, the sender broadcasters the message to ALL the nodes present in a network.
