Networking devices are products used to connect networks. As computer networks grow in size and complexity, so do the networking devices used to connect them.
However, all networking devices share one or more common purposes.
They allow a greater...
TCP/IP utilities | PING, TRACERT, ARP, Netstat, NBTSTAT/NetBIOS, IPCONFIG, NSLookup, WINIPCFG
Virtually every operating system with networking capabilities includes support for the TCP/IP protocols, and in most cases, the TCP/IP stack includes an assortment of utilities that enable you to gather information about the various protocols and about...

Network Support | Netstat (Network Statistics)
Netstat is a command-line program that displays information about a computer’s current network connections and about the traffic generated by the various TCP/IP protocols.
On UNIX computers, the program is simply called netstat, and on Windows computers,...
Network Support | Address Resolution Protocol (ARP)
The Address Resolution Protocol (ARP) enables a computer to convert IP addresses to the hardware addresses that the data-link layer protocol need to transmit frames. IP uses ARP to discover the hardware addresses to which each of its datagrams...
Network Support | TRACERT
You can use the TRACERT utility to determine the route that a packet may take to get from one device to another (if a route exists). You can also use this utility to determine the time that it takes the packet to reach routers and to identify Sluggish...
Network Support | PING Command
You can use the PING utility to query another IP device on the network to determine if the IP device is “alive” and how long it takes a packet to reach the device. This utility is one of the first tools you should use if the problem...
