22
Q

What is a data collision?

A

When 2 or more computers try to place a data package on the network at exactly the same time. (The network is set to deal with this, however.)

23
Q

Different networks are compatible if they have the same ______.

A

Protocol

24
Q

What is encryption?

A

Encryption is the conversion of data into a form, called a ciphertext, that cannot be easily understood by unauthorized people.

25
Q

What is decryption?

A

Decryption is the process of converting encrypted data back into its original form, so it can be understood.

26
Q

Why is encryption necessary?

A

To make sensitive data inaccessible for security purposes.

27
Q

What are access points?

A

An access point is wireless location in which computers can connect to, like a WiFi hotspot. Unfortunately it is slower than a cabled connection. The hardware for this is a WAP.
