ISTM 210 Exam 2 [2026/2027] | UPDATED ACTUAL
Exam Question and Answer | Final Review Guide
• Computer Network -✓✓ two or more computers connected together to communicate
and share resources
• Server -✓✓ Central Computer in a network
• Clients -✓✓ computers connected to a server
• Node -✓✓ every device connected to a network
• Peripheral Device -✓✓ printer, scanner, etc.
• Network Interface Controller (NIC) -✓✓ computer hardware component that connects
a computer to a network
• Protocol -✓✓ standard language that exists in order for the connected computers to
communicate (2nd component of a network)
• Physical Cable System -✓✓ connects the networks together (3rd component all
networks have in common)
• Twisted Pair -✓✓ 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 -✓✓ central location of a computer network that serves as the "traffic
cop" or network connect and communication
• Transmission Control Protocol/Internet Protocol (TCP/IP) -✓✓ 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) -✓✓ another common network, mainly used for video
streaming, does not guarantee reliability
• Network Operating System(NOS) -✓✓ software that control the entire network,
responsible for the network traffic control, administering packets, file management,
backup, security
, • Network Administrator -✓✓ responsible for smooth network operations, performance
and implementation of new nodes and networks
• Topology -✓✓ mapping of the physical network and logical interconnections between
nodes
• Bus topology -✓✓ (linear bus) each of the networks nodes are connected to a common
linear backbone that has two end points
• Star Topology -✓✓ named for star shape created by nodes that radiate around a
central node, MOST COMMON TYPE
• Ring topology -✓✓ 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) -✓✓ 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) -✓✓ computer network that connects two or more LANs
that are located on a campus, or an organization's national headquarters
• Metropolitan Area Networks (MAN) -✓✓ 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) -✓✓ 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 -✓✓ computer whose sole purpose is to connect to the network and
nothing else
• Peer to peer network (P2P) -✓✓ computer networks that generally connect computers
directly to one another without the use of a server, common for sharing audio and
videos
• Internet -✓✓ world's largest network that connects thousands of other networks
together including LANs, CANs, MANs, and WANs
• Password -✓✓ secret word or combination of keyboard characters typed in by a user
to authenticate ID
