QUESTIONS AND ANSWERS VERIFIED
SOLUTIONS GRADED A+
⩥ Tangible User Interface. Answer: An interface in which a person
interacts with digital information through the physical environment
⩥ Virtual Network. Answer: Create peer-to-peer connections between
computers.
⩥ mesh network. Answer: network topology in which each node relays
data for the network
⩥ TCP/IP. Answer: most common protocol which establishes the
connection, and data packet quality transmission. The first two bytes are
assigned by the Internet Service Provider (ISP), and the last two bytes
are assigned by the client.
⩥ Open System Interconnection (OSI). Answer: consists of seven layers
and is an international standard that governs or guides the development
of data communication protocols
,the seven layers are: application, presentation, session, transport,
network, data link, and physical.
⩥ Telecommunications Network. Answer: Enables the exchange of
information between end users across nodes and links.
⩥ Star network. Answer: Router in middle of each computer connected
to the router/hub.
⩥ ring network. Answer: each computer connected to the next computer;
cheaper to install; less effiecient.
⩥ network host. Answer: node/computer connected with an IP address
⩥ Convergence. Answer: the ability for a telecommunication network to
carry voice, data, and video
⩥ Sniffing. Answer: eavesdropping on network traffic in order to acquire
traffic data packets and decoding. The information gathered can be used
to hack into a network; the most common attack, as signals travel
through the air
⩥ Extranet. Answer: an intranet that can be partially accessed by
authorized outside users, enabling businesses to exchange information
over the Internet securely.
, ⩥ ARPANET. Answer: an early packet switching network and the first
network to implement the protocol suite TCP/IP. Both technologies
became the technical foundation of the Internet.
⩥ Information Repository. Answer: Allows businesses to store important
information and documents that can be accessed remotely by
stakeholders; sometimes a fee for the service is charged.
⩥ 1G Networks. Answer: The first cellular mobile networks; could only
transmit analog signals on radio frequency.
⩥ 2G Networks. Answer: Has a 64 kbps speed
⩥ 3G Networks. Answer: 384 kbps speed
⩥ 4G Networks. Answer: Also called long-term evolution (LTE), these
networks offer speeds of 100,000 kpbs in the Ultra High Frequency
band; offers voice, data, and video.
⩥ Wi-Fi Protected Access (WPA). Answer: A wireless (tunneling)
encryption protocol that provides secure data transmission over an
insecure network.
