ISTM 210 Exam 2 (Phinney) ACTUAL UPDATED QUESTIONS AND CORRECT
ANSWERS
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
