CodeHS Intro to Hardware Networking

What is routing in networking?

• Routing in networking is the process of randomly choosing a path for network traffic

• Routing in networking is the process of selecting the worst path for network traffic

• Routing in networking is the process of selecting the best path for network traffic to travel from the source to the destination.

• Routing in networking is the process of sending network traffic in all directions simultaneously

Explain the role of internet hardware in sending information.

• Internet hardware, such as routers and switches, receive and forward data packets to their destinations based on IP addresses.

• Internet hardware uses satellite signals to transmit data across the globe

• Internet hardware sends information through physical cables directly to the recipient's device

• Internet hardware relies on Morse code to transfer information between devices

What are internet addresses and how are they used?

• IP addresses are numerical labels assigned to devices connected to a network, used for identification and routing of data.

• Internet addresses are symbols used in coding languages to represent functions.

• Internet addresses are physical locations on the globe used for navigation.

• Internet addresses are random sequences of characters used for encryption purposes.

Describe packets and protocols in networking.

• Protocols are software applications for browsing the internet.

• Packets are physical devices in networking.

• Packets are used only in wireless networks.

• Packets are data units in a network. Protocols are rules for data format, transmission, and reception.

How does a router determine where to send packets?

• Destination IP address and routing table

• Packet size and timestamp

• Source IP address and MAC address

• Random selection

What are the common types of internet hardware used for networking?

• firewalls

• repeaters

• routers, switches, modems, access points

• hubs

What is the purpose of IP addresses in networking?

• IP addresses determine the physical location of devices.

• IP addresses uniquely identify devices on a network.

• IP addresses manage network security.

• IP addresses encrypt data.

How do protocols ensure reliable communication over a network?

• By defining rules and procedures for data transmission, error detection and correction, flow control, and addressing.

• By sending data without any rules or procedures

• By using incorrect addressing and error detection methods

• By allowing unlimited data flow without any control

Explain the difference between TCP and UDP protocols.

• TCP and UDP are the same protocol.

• UDP is connection-oriented and provides reliable data delivery.

• TCP is connectionless and does not guarantee delivery.

• TCP is connection-oriented and provides reliable data delivery, while UDP is connectionless and does not guarantee delivery.

Why is it important to have a well-defined routing table in a network?

• Having a well-defined routing table ensures efficient data packet delivery and prevents network congestion.

• A well-defined routing table leads to slower data transmission

• A well-defined routing table is unnecessary for network performance

• Having a well-defined routing table increases network security risks
