Routing & Network Hardware

What is a hub in networking?

A Hub is a device that connects all segments of the network together in a star topology Ethernet network.

What is the primary function of a Network Interface Card (NIC)?

A NIC connects a computer to the network, providing physical, electrical, and electronic connections.

What is a bridge in networking?

A network device that connects two similar network segments and separates traffic to reduce collisions.

How does a switch differ from a hub?

A switch recognizes frames and checks the source and destination MAC addresses, while a hub does not.

What is the purpose of a router?

A router forwards data packets between computer networks and performs traffic directing functions on the Internet.

What does routing refer to?

Routing is the process of forwarding data packets from source to destination and maintaining routing tables.

What is a static route?

A static route is a manually created route that does not change unless manually configured.

What does DHCP stand for and what is its purpose?

Dynamic Host Configuration Protocol (DHCP) automatically assigns IP addresses to devices on a network.

What does NAPT stand for and what does it do?

Network Address Port Translation (NAPT) allows local network hosts to connect to the Internet by translating private IP addresses to a public IP address.

What distinguishes Interior Gateway Protocols (IGP) from Exterior Gateway Protocols (EGP)?

IGPs manage routing within an Autonomous System, whereas EGPs manage routing between different Autonomous Systems.

What type of routing does BGP use?

Border Gateway Protocol (BGP) uses a modified distance-vector approach to determine routing paths.

What is EIGRP?

Enhanced Interior Gateway Routing Protocol (EIGRP) is a hybrid routing protocol developed by Cisco that uses the best features of both distance vector and link state protocols.
