computer uses with various types of interface cards and equipment Popular bus architectures are ISA, PCI, and PCMCIA for laptops When you install a network card, you will need to be familiar with what bus slot you will place the card into
The network card uses a transceiver to pick up the electrical signals and send
electrical signals on the wire There are two types of transceivers: built in and external The transceivers for twisted pair and thinnet usually are built into the network card, whereas the transceiver for thicknet is usually an external one
When you are con guring the network card, you may need to specify the
transfer rate so that it supports the device you are connecting to You also may need to specify the transceiver you intend to use, the transmission type, and whether to use half -duplex or full -duplex
Simplex transmissions only allow for data to be sent in only one direction
Half-duplex allows for data to be sent and received, but not at the same time Full-duplex allows data to be sent and received at the same time
Hubs, MAUs, and Repeaters
Hubs are the central location to which all cabling must connect in most
topologies

Networking Components
When exam time comes, remember the difference between an active and
a passive hub An active hub contains electronic components to boost the signal A passive hub does not
A multistation access unit (MAU) is a device to which multiple workstations
are connected in order to communicate on a Token Ring network
Because the signal gets weaker over distance, repeaters are used to regenerate
the signal so that it can continue in its travels
Hubs, MAUs, and repeaters are layer-1 devices
Bridges and Switches
A bridge is used to create multiple segments on the network The bridge
will forward network traf c only to the destination segment and not to all segments, thus acting as a ltering device to improve network performance
A switch lters network traf c by sending data only to the port on the switch
where the destination system resides
Switches are replacing hubs, and network administrators who wish to
improve network performance should replace their hubs with switches
Some switches support virtual LANs (VLANs) A VLAN is a group of
ports on the switch that make up their own logical network Systems on a particular VLAN can communicate only with other systems on the same VLAN unless a router is used The VLAN also acts as a broadcast domain, because broadcast traf c is sent only to ports in the VLAN where the sender of the broadcast traf c exists
Bridges and switches are layer-2 devices
Routers and Brouters
A router is a layer-3 device that sends data from one network to another
using a layer-3 address such as an IP address
Routers are used by routable protocols such as IPX /SPX, TCP/IP, and
AppleTalk
A brouter is a device that combines a bridge and a router together The
brouter will act as a router for routable protocols but will act as a bridge for nonroutable protocols such as NetBEUI

Gateways and Firewalls
A gateway is a device that is used to join dissimilar environments together The gateway converts data from one side of the gateway to a format that the
other side of the gateway will understand
A rewall is a device that blocks all network traf c from passing through
the rewall in order to protect private network resources The rewall may be con gured to allow selected traf c to pass through For example, most companies have a web server that publishes their web site, so they will need to allow HTTP traf c to pass through the rewall
Other Networking Devices
Modems are used as remote connectivity devices to connect systems across
telephone wires The modem converts digital signals to analog on the sending computer and converts analog signals to digital on the receiving computer
CSU/DSU is a network device that allows an organization to connect to a
high-speed link such as a T1 or T3
ISDN is a digital service that is used to connect systems over a digital phone
line and to receive transmission rates faster than conventional modems
