ARP-

Address Resolution Protocol is a utility of IP that resolves IP addresses to MAC addresses. Datagram- A packet of data and other delivery information that is routed through a packet-switched network or transmitted on a localarea network.

Default Gateway-

An intermediate network device on the local network that’s configured to receive datagrams sent to IP addresses that are not found on the local network. The Gateway has knowledge of the network IDs of the other networks in the internet, so it can forward the packets to other gateways until the packet is eventually delivered to a gateway connected to the specified destination.

DHCP-

Dynamic Host Configuration Protocol, which offers dynamic configuration of IP addresses and related information. DHCP provides safe, reliable, and simple TCP/IP network configuration, prevents address conflicts, and helps conserve the use of IP addresses through centralized management of address allocation.

DNS-

Domain NameServers are servers containing information about a portion of the DNS database, which makes computer names available to client resolvers querying for name resolution across the internet.

FQDN-

Fully Qualified Domain Name is part of the TCP/IP naming convention known as the Domain Name System. A computer names consist of two parts: host names with their domain names appended to them. example: a host with host namecorp001 and DNS domain name trey-research.com has an FQDN of corp001.trey-research.com.

Hosts file-

A small ASCII text file that maps IP addresses to Host names. Used by the IP protocol. example: bigservr.acme.com.

ICMP-

Internet Control Message Protocol is a utility functioning at the OSI’s Network (Microsoft’s Internet) layer. Its function is to report errors and messages regarding the delivery of IP datagrams.

IP Alias-

Configuring multiple IP addresses to one MAC address.

LMHosts file-

A small ASCII file that maps IP addresses to NetBIOS(computer) names. Used by the NetBEUI protocol.

MAC address-

12 HEX digits grouped in twos, InterNIC assigns 1^st ½ for Mfg.’s Id and 2^nd ½ is the card number from the Mfg. example: 2F-D0-19-C1-2A-15.

NetBIOS name-

The name used to identify a computer system on a Microsoft Network, a.k.a.: computer name.

Ping-

Packet Internet Groper is a utility of IP that requests an acknowledgement that a particular IP address exists on the network. PING utilizes ICMP echo request and reply mechanisms.

Port-

A location in RAM that’s reserved for data input\output from various programs, there are 65,536 total w\ 2,048 portsreserved for the OS’s usage. Once a connection has been made between ports, the OS will move them to another area, hereby freeing up an assigned port number. example: telnet = port 23 by default.

Proxy Server-

Configuration of multiple Port addresses to one IP address. For example: multiple client computers utilizing one server connected to the Internet w\ an InterNIC address. Viewed from the Internet side, it appears not that multiple clients are downloading a few WebPages and files but that only one system is consistently downloading a large number of WebPages & files.

Slash/X-

A numbering convention of the InterNIC. Instead of using the dotted quad (xxx.xxx.xxx.xxx) format, the InterNIC assigns an x amount of network bits and the unassigned remaining bits are used by the Administrator to assign Host ID’s. Written similar to: nnnnnnnnnn/hh, where n= Network bits and H= host bits.

Sockets-

A combination of IP address plus Port address.

Subnettin g-

The process of taking a portion of an IP Host(s) address and configuring it for Network ID usage.

TCP-

Transmission Control Protocol. An IP protocol that guarantees the delivery of a datagram packet.

UDC-

User Datagram Protocol. An IP protocol that doesn’t guarantee the delivery of a datagram packet.

UNC-

Universal Naming Convention. A method of writing a Shared Resource address as seen from a network’s viewpoint. For example: \\sharename\directory\filename, where servernameis the Server’s NetBIOS identifier and sharename is the Shared Resource identifier.

WINS-

Windows Internet Name Service is a service that resolves Windows NT networking computer names to IP addresses in a routed environment. A WINS server provides\handles name registrations, queries, and releases.
