Networking Terms- Router: Connects 2 or more networks using the network layer.
- Gateway: Manages communications between different protocol families.
- Bridge: Connects 2 or more networks using the data link layer.
- Hop: Used to describe a jump through a router to the next network.
- AppleTalk: The network protocol for Apple Macintosh Systems.
- LocalTalk: AppleTalk protocol on twisted pair cabling (ie, PhoneNet).
- EtherTalk: AppleTalk protocol on EtherNet cable with interface card.
- TokenTalk: AppleTalk protocol on Token Ring cabling with interface card.
AppleTalk Limits
- Phase I supports up to 254 nodes, by number.
- Phase II supports (theoretically) 16 million nodes by range or number.
- LocalTalk should only address up to 32 nodes.
- LocalTalk Network is identified by a single network number.
- Extended AppleTalk networks are identified by network range.
- Extended AppleTalk networks support zone lists.
OSI Model
Applies to TCP/IP and other networking protocols:
- Layer 7 - Application
- Layer 6 - Presentation
- Layer 5 - Session
- Layer 4 - Transport
- Layer 3 - Network
- Layer 2 - Data link
- Layer 1 - Physical
Topology:- Bus: All nodes connected in one line (daisy chain).
- Star: All nodes connected to a central hub.
- Ring: All nodes connected in a closed loop.
