A _________ is the simplest device for connectivity. It enables a network to extend by repeating
and amplifying electric signals between different cable lengths. _____ work at the physical
layer in the OSI model.
________ are used to connect different LAN segments. They work at the data link layer of the OSI
model. A _______ verifies the media access control (MAC) address of an approaching signal to
confirm whether the destination computer is on that specific network segment
_____ function at the network layer of an OSI model. These are used to connect different
networks. A _____ can look at the destination IP address of a data packet and use a routing
table to forward it to the appropriate destination
_____ are similar to bridges in their function. They operate at the data link layer and forward
data packets based on the MAC address. Unlike a bridge, a ____ uses hardware in the form of
a circuit to ____ data directly to the destination computer or network.
A _______ functions at the application layer of the OSI model and, therefore, performs much more complex tasks than a router or a bridge. Routers are used to connect two different environments or topologies.
______ are multiport networking devices that are used to connect private data over public
data circuits. These ___function at the data link layer of the OSI model
A _______is used to send several transmission streams simultaneously, over one physical circuit. It is also used to split a received stream into component parts
An ____ _______acts as a concentration point and provides dial-in and dial-out connection from the internal network
______s enable transmission of data over voice grade telephone lines by translating analog signals into digital form and converting it back into a digital signal at the destination point
____ _______ _____ are used to connect a LAN to a WAN. A CSU provides a digital interface to data terminal equipment (DTE) and a physical interface to the data circuit-terminating equipment (DCE) device.
Channel service units (CSUs)
