(10 cards)
What are the differences between straight-through and crossover Ethernet cable configurations?
A straight-through Ethernet cable is used to connect devices of different types, such as a computer to a switch or a router to a modem, while a crossover Ethernet cable is used to connect devices of the same type, such as a computer to a computer or a switch to a switch.
Which of the following best describes the Transport layer in the OSI model?
Manages end-to-end communication between applications.
What is the difference between physical and logical addresses in networking?
Physical addresses are unique identifiers assigned to devices at the data link layer of the OSI model, while logical addresses are unique identifiers assigned to devices at the network layer of the OSI model.
What are logical ports?
Virtual ports that are created by network devices to establish a connection between two physical devices.
HTTP uses logical port
80
while
HTTPS
uses logical port 443. SSH uses logical port
22
while
SMB
uses logical port 445. (You may select more than one response.)
True
What are the three main logical port groups?
Well-known ports, Registered ports, and Dynamic/Private ports.
What are the risks and vulnerabilities of wireless network security?
Unauthorized access, data interception, and network intrusion.
What is one advantage of the TCP/IP model over the OSI model?
Provides a standardized reference model for network communication, allows for interoperability among different vendors’ networking equipment and protocols.
What is the DHCP protocol used for in computer networking?
DHCP (Dynamic Host Configuration Protocol) is used to automatically assign IP addresses to devices on a network.
What is a network topology?
A network topology describes the structure of a network and represents all the connections between all components in a network.
