Answers (2026/2027) | Full Revision Pack |
Accurate Responses | A+
• Computer Network. CORRECT ANSWER: two or more computers connected
together to communicate and share resources
• Server. CORRECT ANSWER: Central Computer in a network
• Clients. CORRECT ANSWER: computers connected to a server
• Node. CORRECT ANSWER: every device connected to a network
• Peripheral Device. CORRECT ANSWER: printer, scanner, etc.
• Network Interface Controller (NIC). CORRECT ANSWER: computer hardware
component that connects a computer to a network
• Protocol. CORRECT ANSWER: standard language that exists in order for the
connected computers to communicate (2nd component of a network)
• Physical Cable System. CORRECT ANSWER: connects the networks together
(3rd component all networks have in common)
• Twisted Pair. CORRECT ANSWER: most common type of networking cables,
specialized wire that cancels out electromagnetic interference from other electronic
devices and increases reliability
Networks can be connected wirelessly but generally for a smaller network
• Network Hub. CORRECT ANSWER: central location of a computer network
that serves as the "traffic cop" or network connect and communication
• Transmission Control Protocol/Internet Protocol (TCP/IP). CORRECT
ANSWER: most common protocol that breaks large files into packets and
guarantees reliability of the computer file received by the networks end user
• User Datagram protocol (UDP). CORRECT ANSWER: another common
network, mainly used for video streaming, does not guarantee reliability
, • Network Operating System(NOS). CORRECT ANSWER: software that control
the entire network, responsible for the network traffic control, administering
packets, file management, backup, security
• Network Administrator. CORRECT ANSWER: responsible for smooth network
operations, performance and implementation of new nodes and networks
• Topology. CORRECT ANSWER: mapping of the physical network and logical
interconnections between nodes
• Bus topology. CORRECT ANSWER: (linear bus) each of the networks nodes are
connected to a common linear backbone that has two end points
• Star Topology. CORRECT ANSWER: named for star shape created by nodes
that radiate around a central node, MOST COMMON TYPE
• Ring topology. CORRECT ANSWER: shaped like a ring, each computer node is
connected to 2 other computers, data transmitted in a circle, least used for
microcomputers
• Local Area Network (LAN). CORRECT ANSWER: relatively small, typically in
a single building, serve small businesses or small parts of a large business like an
accounting department
• Campus Area network (CAN). CORRECT ANSWER: computer network that
connects two or more LANs that are located on a campus, or an organization's
national headquarters
• Metropolitan Area Networks (MAN). CORRECT ANSWER: computer network
that connects two or more LANS or CANS together within the boundaries of a city
or town, ex: bank with different branch locations
• Wide Area Networks (WAN). CORRECT ANSWER: computer netwirks that
encompass a wide geographical area and connect LANs, CANs, and MANs
together, often rely on telephone companies transmission facilities to connect
smaller networks together, ex: airlines
• Dumb terminal. CORRECT ANSWER: computer whose sole purpose is to
connect to the network and nothing else
