SNMP:
Simple Network Management Protocol is the network management protocol of TCP/IP. In
SNMP, agents (which can be hardware as well as software) monitor the activity in the various
devices on the network and report to the network console workstation. Control information about
each device is maintained in a structure known as a management information block.
Static IP Addressing:
A method of assigning IP addresses to clients on the network. In networks
with Static IP addresses, the network administrator manually assigns an IP address to each
computer. Once a Static IP address is assigned, a computer uses the same IP address every time it
reboots and logs on to the network, unless it is manually changed.
Subnet:
Found in larger networks, these smaller networks are used to simplify addressing between
numerous computers. Subnets connect to the central network through a router, hub or gateway.
Each individual wireless LAN will probably use the same subnet for all the local computers it talks to.
TCP/IP:
Transmission Control Protocol / Internet Protocol
is the protocol suite developed by the
Advanced Research Projects Agency (ARPA). It is widely used in corporate Internet works, because
of its superior design for WANs. TCP governs how each packet is sequenced for transmission
through the network. The term TCP/IP is often used generically to refer to the entire suite of related
protocols.
VPN:
A type of technology designed to increase the security of information transferred over the
Internet. VPN can work with either wired or wireless networks, as well as with dial-up connections.
VPN creates a private encrypted tunnel from the end user's computer, through the local wireless
network, through the Internet, all the way to the corporate servers and database.
WAN:
A Wide Area Network consists of multiple LANs that are tied together via telephone services
and / or fiber optic cabling. WANs may span a city, a state, a country, or even the world.
WEP:
Wired Equivalent Privacy is a basic wireless security as described in the IEEE 802.11
standard. In some instances, WEP may be all a home or small-business user needs to protect
wireless data. WEP is available in 40-bit (also called 64-bit), or in 108-bit (also called 128-bit)
encryption modes. As 128-bit encryption provides a longer algorithm that takes longer to decode, it
can provide better security than basic 40-bit (64-bit) encryption.
Wi-Fi:
An interoperability certification for wireless local area network (LAN) products based on the
Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.
WLAN:
A Wireless LAN does not use cable to transmit signals, but rather uses radio to transmit
packets through the air. Radio Frequency (RF) is the commonly used type of wireless transmission.
