TCP/IP Hr 1 and 2
Teach Yourself TCP/IP in 24 Hours , Hr 1 and 2
| Question | Answer |
|---|---|
| ARPAnet | An experimental network that was the birthplace of TCP/IP |
| Domain name | An alphanumeric name associated with an IP address through TCP/IP's DNS name service system. |
| Gateway | A router that connects a LAN to a larger network. Sometimes applies specifically to a router that performs some kind of protocol conversion. |
| IP Address | A logical address used to locate a computer or other networked device such as a printer on a TCP/IP network. |
| Logical address | A network address configured through the protocol software. IP address when it comes to TCP/IP. |
| Name Services | A service that associates human-friendly alphanumeric names with network addresses. |
| Physical address | A permanent address burned into a network adapter in the factory. Also called a MAC address. |
| Port | An internal address that provides an interface between an application and TCP/IP's Transport layer. |
| Protocol System | A system of standards and procedures that enables computers to communicate over a network. |
| RFC (Request for Comment) | An official technical paper providing relevant information on TCP/IP or the Internet. You can find the RFC's on the Internet (www.rfc-editor.org) |
| Router | A network device that forwards data by logical address and can be used to segment large networks into smaller subnetworks. |
| TCP/IP | A network protocol suite used on the Internet and also on many other networks. |
| Application Layer | The layer of the TCP/IP stack that supports network applications and provides an interface to the local operating environment. |
| Datagram | The data package passed from the Internet layer to the Network Access layer, or a data package passed from UDP at the Transport layer to the Internet layer. |
| Frame | The data package created at the Network Access layer. |
| Header | A bundle of protocol information attached to the data at each layer of the protocol stack. |
| Internet layer | The layer of the TCP/IP stack that provides logical addressing and routing. |
| IP (Internet Protocol) | The internet layer protocol that proprovides logical addressing and routing. |
| Message | In TCP/IP networking, a message is the data package passed from the Application layer to the Transport layer. |
| Network Access layer | The layer of the TCP/IP stack that provides an interface with the physical network. |
| Segment | The data package passed from TCP at the Transport layer to the Internet layer. |
| TCP (Transmission Control Protocol) | A reliable, connection-oriented protocol of the Transport layer. More details later! |
| Transport layer | The layer of the TCP/IP stack that provides error control and acknowledgment and serves as an interface for network applications. |
| UDP (User Datagram Protocol) | An unreliable, connectionless, protocol of the Transport layer. More details later! |
