3. The Hub Network (originally "The Hub" from 2010 to 2013) is an American
digital cable and satellite television channel that is owned as a joint venture
between Discovery Communications and Hasbro. The Hub Network's
programming is acquired and produced by Hasbro, and is distributed by

network with a mix of original and acquired children's programs, reruns of
older television sitcoms and dramas (particularly during the evening hours) and
feature films.[1] As of August 2013, approximately 72,237,000 American
households (63.25% of households with television) receive the Hub Network.
5. A router is a device that forwards data packets between computer
networks. This creates an overlay internetwork, as a router is connected to
two or more data lines from different networks. When a data packet comes
in one of the lines, the router reads the address information in the packet to
determine its ultimate destination. Then, using information in its routing
table or routing policy, it directs the packet to the next network on its
journey. Routers perform the "traffic directing" functions on the Internet. A
data packet is typically forwarded from one router to another through the
networks that constitute the internetwork until it reaches its destination
node.
7. A modem (modulator-demodulator) is a device
that modulates an analog carrier signal to encode digital information and
demodulates the signal to decode the transmitted information. The goal is to produce
a signal that can be transmitted easily and decoded to reproduce the original digital
data. Modems can be used with any means of transmitting analog signals, from light
emitting diodes to radio. A common type of modem is one that turns the digital
data of a computer into modulated electrical signal for transmission over telephone
lines and demodulated by another modem at the receiver side to recover the digital
data.
