Is a lossless compression format

Creates a dictionary of common letter combinations to encode words with fewer characters

Creates a dictionary of smaller letters so less space is used

Sends the dictionary with the data

Doesn't need to send the dictionary with the data

Uses at least one key to cipher data

Is only used on text

Can be symmetric or asymmetric

Is impossible to break

Has developed a lot as processing power has increased

Are the most secure types of encryption

Use a single key to encode/decode

Use multiple keys to encode/decode

Include XOR, Caesar and Route

Include RSA, Diffie-Hellman and DSS

Include XOR, Caesar and Route

Include RSA, Diffie-Hellman and DSS

Often requires considerable processing power

Is impossible to break

Is being threatened by the possibility of quantum computing

Can be brute-force attacked

Is very widely used, even in small businesses
