Glad to help. Since you found MAC & IP addresses in your book, I won't go into them much. But here's some characteristics of both addresses which you might need to know:

A MAC address is 48 bits in length and is expressed as twelve hexidecimal digits. The first six ID the mfg and is the Organizational Unique Identifier (OUI).

IP address is considered a “Dotted-Decimal” number and is 32 bits in length. (ie 192.168.5.1)


Since we are talking about the OSI Model you might also encounter "Encapsulation"

The Encapsulation Process is: Data > Segments > Packets > Frames > Bits.

The Data from the Application, Presentation, and Session Layers (considered the upper layers 7, 6, & 5) is placed into Layer 4 (Transport Layer) Segments. The Segments are packaged into Layer 3 (Network Layer) Packets. The packets are placed into Layer 2 (Data Link Layer) Frames. And the frames are placed as a series of Bits on Layer 1 (the Physical Layer)
