network. Every client and server station must have a unique IP address. Clients are assigned either a permanent address or have one dynamically assigned to them via DHCP. IP addresses are written as four sets of numbers separated by periods (for example, 211.23.181.189).
LAN
LANs (Local Area Networks) are networks that serve users within specific geographical areas, such as in a company building. LANs are comprised of servers, workstations, a network operating system, and communications links such as the router.
MAC Address
A MAC address is a unique serial number burned into hardware adapters, giving the adapter a unique identification.
(Network) AdministratorThe network administrator is the person who manages the LAN within an organization. The administrator's job includes ensuring network security, keeping software, hardware, and firmware
NTP (Network Time Protocol) is used to synchronize the
A packet is a portion of data that is transmitted in network communications. Packets are also sometimes called frames and datagrams. Packets contain not only data, but also the destination IP address.
PingPing (Packet Internet Groper) is a utility used to find out if a particular IP address is present online, and is usually used by networks for debugging.
PortPorts are the communications pathways in and out of computers and network devices (routers and switches). Most PCs have serial and parallel ports, which are external sockets for connecting devices such as printers, modems, and mice. All network adapters use ports to connect to the LAN. Ports are typically numbered.
ProtocolA protocol is a rule that governs the communication of data.
ServerServers are typically powerful and fast machines that store programs and data. The programs and data are shared by client machines (workstations) on the network.
SMTPSMTP (Simple Mail Transfer Protocol) is the standard Internet
