AP CS Principles Test 8 Review - Networking and Parallel Computing

Flashcards for reviewing vocabulary related to networking and parallel computing concepts.

Internet

A global network of computers that can communicate with each other using common protocols.

World Wide Web

The collection of web pages and related data that can be accessed through the Internet.

IP (Internet Protocol)

A common protocol used to transmit data on the internet.

TCP (Transmission Control Protocol)

A common protocol used to transmit data on the internet.

FTP (File Transfer Protocol)

A common protocol used to transmit data on the internet.

HTTP (Hypertext Transfer Protocol)

A common protocol used to transmit data on the internet.

Packets

Chunks of data that are transmitted over a network.

HTML (Hypertext Markup Language)

The language used to represent web pages.

Encryption

Using a mathematical algorithm to encode data to be transmitted, to prevent eavesdroppers from being able to read the data.

Symmetric Encryption

Encryption that uses the same key for both encryption and decryption.

Public Key Encryption

Encryption that uses two mathematically related keys (the public and the private key); data encrypted with one key can be decrypted with the other.

Digital Signature

Encrypting a document (or a hash of the document) with your private key lets anyone read it, but shows your authorship of the document.

Parallel Computing

Involves running more than one process at the same time, using multiple cores (processors) within one computer or multiple computers (this is typically called distributed computing).

Sequential Computing

Solves only one problem at a time, then moves on to the next.

Core (Processor)

An individual computing unit within a computer's CPU.
