In this module, we introduced the following terms:
- Domain Name Service (DNS): Domain Name Service: resolves domain names to IP addresses
- Ethernet: A LAN developed by Xerox in 1976. Ethernet became a widely implemented network from which the IEEE 802.3 standard for contention networks was developed. It uses a bus topology and the original Ethernet relies on CSMA/CD to regulate traffic on the
main communication line.
- Gateway: A machine which links two networks.
- Loopback address: 127.0.0.1. This address is used for diagnostics.
- Netmask : A 32-bit bit mask which shows how an Internet address is to be divided into network, subnet and host parts.
- Network Information Database: The NID (Network Information Database) provides a means to synchronize account information across computer systems.
- Point-to-point protocol (PPP): A protocol for connecting to the Internet. PPP provides error checking and compression of the IP and TCP headers.
- Resolver library: The TCP/IP protocol library software that formats requests to be sent to the Domain Name Server for hostname to Internet address conversion.
- TCP/IP: TCP/IP is the network protocol suite used by the Internet and most local area networks.
- Telnet: A TCP/IP application that is used for remote terminal access and can be used to administer a UNIX machine.
