After a client and server has used Kerberos to prove their
identity, they can also encrypt all of their communications to
assure privacy and data integrity as they go about their
business.
KVM Keyboard, video and mouse interface to a server.
LDAP Lightweight Directory Access Protocol. A software protocol
for enabling anyone to locate organizations, individuals, and
other resources such as files and devices in a network,
whether on the Internet or on a corporate intranet.
LDAP is a "lightweight" (smaller amount of code) version of
DAP (Directory Access Protocol), which is part of X.500, a
standard for directory services in a network.
MAC Medium Access Control. Internationally unique hardware
identification address that is assigned to the NIC (Network
Interface Card) which interfaces the node to the LAN.
MTU Short for Maximum Transmission Unit, the largest physical
packet size, measured in bytes, that a network can transmit.
Any messages larger than the MTU are divided into smaller
packets before being sent.
Every network has a different MTU, which is set by the
network administrator. On Windows, you can set the MTU of
your machine. This defines the maximum size of the packets
sent from your computer onto the network. Ideally, you want
the MTU to be the same as the smallest MTU of all the
networks between your machine and a message's final
destination. Otherwise, if your messages are larger than one
of the intervening MTUs, they will get broken up
(fragmented), which slows down transmission speeds.
Trial and error is the only sure way of finding the optimal
MTU, but there are some guidelines that can help. For
example, the MTU of many PPP connections is 576, so if you
