Exploring Computer Networks

What are the four layers of the TCP/IP architecture?

• Application, Transport, Internet, Network Interface

• Network, Transport, Link, Session

• Application, Network, Transport, Physical

• Session, Transport, Internet, Data Link

Explain the function of the Internet Protocol (IP) in TCP/IP.

• IP manages user authentication and access control for network resources.

• IP encrypts data to ensure secure transmission over the network.

• IP is responsible for establishing a physical connection between devices.

• The function of the Internet Protocol (IP) in TCP/IP is to facilitate the addressing and routing of data packets between devices on a network.

What is the difference between TCP and UDP?

• TCP is reliable and connection-oriented; UDP is faster and connectionless.

• UDP guarantees delivery of packets, while TCP does not.

• TCP and UDP are both connection-oriented protocols.

• TCP is faster and connectionless; UDP is reliable and connection-oriented.

Describe the role of the Transport layer in TCP/IP.

• The Transport layer encrypts data for secure transmission.

• The Transport layer manages end-to-end communication, data segmentation, error detection, flow control, and reliable delivery using protocols like TCP and UDP.

• The Transport layer is responsible for routing packets between networks.

• The Transport layer handles physical connections and signal transmission.

What are the advantages of wireless networking?

• Increased cabling requirements

• Limited device support

• Reduced mobility options

• Advantages of wireless networking include flexibility, ease of installation, mobility, reduced cabling costs, and support for multiple devices.

What is the purpose of a wireless access point?

• To enhance the security of wired networks.

• To provide wireless connectivity to devices within a network.

• To serve as a central hub for wired connections.

• To connect devices to the internet via Ethernet cables.

Explain the concept of SSID in wireless networks.

• SSID refers to the speed of a wireless connection.

• SSID is a unique identifier for a wireless network.

• SSID is a physical device used to connect to the internet.

• SSID is a type of encryption for wireless networks.

What security protocols are commonly used in wireless networking?

• FTP, SFTP, SCP

• WEP, WPA, WPA2, WPA3

• SSL, TLS, HTTPS

• IPSec, L2TP, PPTP
