UPDATED 2026 COMPREHENSIVE EXAM QUESTIONS AND
ANSWERS SURE A+
Simple Mail Transfer Protocol (SMTP) - ✔✔Used to manage and monitor emails that we
receive.
Packet Switching - ✔✔a mode of data transmission in which a message is broken into a
number of discrete, parsed parts that are sent independently in encapsulated packets,
over whatever route is optimum for each packet, and reassembled at the destination;
what is used when accessing the Internet;
Circuit Switching - ✔✔ideal for communications that require data to be transmitted in
real-time; a constant connection is required before transmission begins.
Repeaters - ✔✔Receive and retransmit/amplify data at a higher power to it can go a
longer distance.
Tangible User Interface - ✔✔An interface in which a person interacts with digital
information through the physical environment
Virtual Network - ✔✔Create peer-to-peer connections between computers.
mesh network - ✔✔network topology in which each node relays data for the network
TCP/IP - ✔✔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) - ✔✔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 - ✔✔Enables the exchange of information between end
users across nodes and links.
Star network - ✔✔Router in middle of each computer connected to the router/hub.
ring network - ✔✔each computer connected to the next computer; cheaper to install;
less effiecient.
, network host - ✔✔node/computer connected with an IP address
Convergence - ✔✔the ability for a telecommunication network to carry voice, data, and
video
Sniffing - ✔✔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 - ✔✔an intranet that can be partially accessed by authorized outside users,
enabling businesses to exchange information over the Internet securely.
ARPANET - ✔✔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 - ✔✔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 - ✔✔The first cellular mobile networks; could only transmit analog signals
on radio frequency.
2G Networks - ✔✔Has a 64 kbps speed
3G Networks - ✔✔384 kbps speed
4G Networks - ✔✔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) - ✔✔A wireless (tunneling) encryption protocol that
provides secure data transmission over an insecure network.
Wi-Fi Protected Access 2 (WPA2) - ✔✔Provides even stronger security than the
original.
Radio Frequency Survey - ✔✔Used to determine wireless access point locations based
upon signal strength.
Electronic Data Interchange (EDI) - ✔✔An automatic electronic exchange of data and
documents from one computer system to another through a standardized messaging
format that does not require human intervention.
