Alpha System should go for implement a local area network
(LAN).
Alpha Systemshould use expendedStar topology. Because it is
Easy to install and wire. No disruptions to the network when
connecting or removing devices. Easy to detect faults and to remove
parts. Point-to-point wiring for individual segments. Supported by
several hardware and software venders.
And it has combine characteristics of linear bus and star
topologies. It consists of groups of
star-configured workstations connected to a linear bus backbone
cable. The expanded stat
topology will allow them expansion of an existing network, and
enable to configure a
network to meet their needs. In the case of cable failure only
single system effects other
systems do not disturbed.

List of com puter network ing devices required:
Gateway: Device sitting at a network node for interfacing with
another network that uses
different protocols.
Router: A specialized network device that determines the next
network point to which it can
forward a data packet towards the destination of the packet.
Unlike a gateway, it
cannot interface different protocols. Works on OSI layer 3.
Switch: a device that allocates traffic from one network segment
to certain lines (intended
destination(s)) which connect the segment to another network
segment. So unlike a
hub a switch splits the network traffic and sends it to
different destinations rather than
to all systems on the network. Works on OSI layer 2.
Hub: Connects multiple Ethernet segments together making them
act as a single segment.
When using a hub, every attached device shares the same
broadcast domain and the
same collision domain. Therefore, only one computerconnected to
the hub is able to
transmit at a time. Depending on the network topology, the hub
provides a basic level
1 OSI model connection among the network objects (workstations,
servers, etc.). It
provides bandwidth which is shared among all the objects,
compared to switches,
which provide a dedicated connection between individual nodes.
Works on OSI layer
1.
Repeater: Device to amplify or regenerate digital signals
received while sending them from one
part of a network into another. Works on OSI layer 1.
Modem: Device that modulates an analog "carrier" signal (such as
sound), to encode digital
information, and that also demodulates such a carrier signal to
decode the transmitted
information, as a computer communicating with another computer
over the telephone
network.
Cable: Depending upon the users financial strength various types
of wires are i.e twisted
pair cable, fiber optic cable, coaxial cable. Cable type. The
most common cable is
unshielded twisted pair, which is most often used with star
topologies.
Fiber can run hundreds of feet, without having a signal boost
with no security issue, andinterference like wireless have.
Fiber cables are slight expensive. It would be better
solution.
