Understanding TCP/IP and Computer Networks

What does TCP stand for in networking?

• Transmission Communication Protocol

• Transmission Control Protocol

• Transmission Connection Protocol

• Transfer Control Protocol

What is the primary purpose of the IP protocol?

• To manage user authentication across networks.

• To route and deliver data packets across networks.

• To encrypt data for secure transmission.

• To establish a connection between devices.

Explain the difference between TCP and UDP.

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

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

• TCP and UDP are both connection-oriented protocols with the same speed.

• UDP is more reliable than TCP and guarantees data delivery.

What is a subnet mask and why is it used?

• A subnet mask is used to encrypt data for secure transmission.

• A subnet mask determines the speed of a network connection.

• A subnet mask is a type of firewall that blocks unwanted traffic.

• A subnet mask is used to define the network and host portions of an IP address.

What is the role of a router in a network?

• The role of a router in a network is to connect different networks and route data packets between them.

• A router amplifies signals to extend network range.

• A router manages user permissions on a network.

• A router is used to store data permanently.

Define what a packet is in the context of networking.

• A packet is a type of network hardware.

• A packet is a protocol for internet security.

• A packet is a software application for data analysis.

• A packet is a formatted unit of data for transmission over a network.

What is the function of the Domain Name System (DNS)?

• To provide web hosting services for websites.

• The function of the Domain Name System (DNS) is to translate domain names into IP addresses.

• To store website content on servers.

• To manage email routing for domains.

How does the three-way handshake work in TCP?

• The three-way handshake involves a SYN packet from the client, a SYN-ACK from the server, and an ACK from the client.

• The three-way handshake consists of a DATA packet from the client, a FIN from the server, and a RESET from the client.

• The three-way handshake involves a single packet exchange between the client and server to establish a connection.

• The three-way handshake is initiated by the server sending a SYN packet, followed by an ACK from the client, and a SYN-ACK from the server.

What is the purpose of the Transmission Control Protocol?

• To establish a physical connection between devices.

• To manage the routing of data packets across the internet.

• To compress data for faster transmission.

• To ensure reliable, ordered, and error-checked delivery of data between applications over a network.

What is an IP address and how is it structured?

• An IP address is a physical address assigned to a computer by the manufacturer.

• An IP address is a unique identifier for a device on a network, structured as IPv4 (e.g., 192.168.1.1) or IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

• An IP address is a unique identifier for a website's domain name.

• An IP address is a type of internet protocol used for email communication.
