Define local area network - CORRECT ANSWER-A local area network
is a group of microcomputers or other workstation devices located
within a small or confined area and are connected by a common cable. A
LAN can be part of a larger backbone network connected to other
LANs, a host mainframe, or public networks.
Describe at least three types of servers - CORRECT ANSWER-A LAN
can have many different types of dedicated servers. Four common
types are file servers, database servers, print servers, and
communication servers. File servers allow many users to share the same
set of files on a common, shared disk drive. A database server usually
is more powerful than a file server. It not only provides shared access
to the files on the server, but also can perform database processing on
those files associated with client-server computing. The key benefit of
database servers is that they reduce the amount of data moved
between the server and the client workstation. They can also minimize
,data loss and prevent widespread data inconsistencies if the system
fails.
Print servers handle print requests on the LAN. By offloading the
management of printing from the main LAN file server or database
server, print servers help reduce the load on them and increase
network efficiency in much the same way that front end processors
improve the efficiency of mainframe computers. Communications
servers are dedicated to performing communication processing. There
are three fundamental types: fax servers, modem servers, and access
servers.
Fax servers manage a pool of fax-boards that enable LAN users to
send or receive faxes. Access servers and modem servers allow users
to dial into and out of the LAN by telephone. Dialing into the LAN is
accomplished with an access server, whereas dialing out is
accomplished with a modem server
Describe the basic components of a wired LAN - CORRECT ANSWER-
The basic components of a wired LAN are the NICs, circuits, access
points, and network operating system.
The network interface card (NIC) allows the computer to be physically
connected to the network cable, which provides the physical layer
connection among the computers in the network.
,The circuits are the cables that connect devices together. In a LAN,
these cables are generally twisted pair from the client to the hub or
server. Outside the building, fiber optic is generally used.
Network hubs and switches serve two purposes. First, they provide an
easy way to connect network cables. In general, network cables can be
directly connected by splicing two cables together. Second, many hubs
and switches act as repeaters or amplifiers. Signals can travel only so
far in a network cable before they attenuate and can no longer be
recognized.
The network operating system (NOS) is the software that controls the
network. Every NOS provides two sets of software: one that runs on
the network server(s), and one that runs on the network client(s). The
server version of the NOS provides the software that performs the
functions associated with the data link, network, and application layers
and usually the computer's own operating system. The client version of
the NOS provides the software that performs the functions
associated with the data link and the network layers, and must interact
with the application software and the computer's own operating
system.
