Understanding the use of common protocols

• Protocols dictate how data is formatted
• What is the purpose of the HTTP protocol?

  Transferring web pages
• What is the primary role of HTTP in the World Wide Web?

  Transferring web content
• What is the main purpose of TCP/IP in internet communications?

  Reliable data transmission
• HTTPS adds a layer of security compared to HTTP.


  True
• What are protocols in computer networks used for?

  Communication between devices
• FTP is used for transferring web pages, while HTTP is for file transfers.

  False
• HTTPS encryption uses SSL/TLS for secure data transmission
• FTP uses separate control and data connections, while HTTP uses a single connection.


  True
• FTP stands for File Transfer Protocol
• FTP supports anonymous access, while HTTP generally requires authentication


  True
• Examples of top-level domains (TLDs) include .com, .org, and .edu
• What is the primary role of DNS in internet communication?

  Translating domain names
• What does the IP part of TCP/IP handle?

  Addressing and routing
• What are protocols in networking defined as?

  Sets of rules and procedures
• Match the protocol with its description:

  HTTP ↔️ Transfers web pages over the Internet

  TCP/IP ↔️ Provides reliable data transmission

  Ethernet ↔️ Facilitates wired LAN connections

  Wi-Fi ↔️ Enables wireless networking
• HTTP manages the establishment and termination of connections
• What does HTTP stand for?

  Hypertext Transfer Protocol
• HTTP defines how web page data should be structured and transmitted between clients and servers.

  True
• Match the protocol with its purpose:

  HTTP ↔️ Transferring web pages and content

  TCP/IP ↔️ Reliable data transmission

  Ethernet ↔️ Enabling wired network connections

  Wi-Fi ↔️ Enabling wireless network connections
• HTTPS encryption ensures secure data transmission over the internet.


  True
• FTP is a network protocol used for transferring files
• Root servers provide the initial lookup for top-level domains in the DNS hierarchy.


  True
• TCP/IP is a suite of protocols that governs how data is communicated over the Internet
• TCP/IP is fundamental for all internet communications, providing a reliable and structured framework for data transmission.

  True
• Protocols provide error handling mechanisms to detect and correct errors during transmission
• Match the protocol with its purpose:

  HTTP ↔️ Transferring web pages and content

  HTTPS ↔️ Secure, encrypted web communication

  FTP ↔️ File uploads and downloads

  DNS ↔️ Domain name resolution

  TCP/IP ↔️ Reliable, ordered data transmission
• What are protocols in computer networks used for?

  Communication between devices
• Protocols ensure error detection and correction during data transmission.


  True
• Match the protocol with its primary purpose:

  HTTP ↔️ Transferring web pages

  TCP/IP ↔️ Reliable data transmission

  Ethernet ↔️ Wired network connections

  Wi-Fi ↔️ Wireless network connections
• HTTP defines how web page data should be structured and transmitted
• What type of encryption does HTTPS use to secure data?

  SSL/TLS
• HTTPS uses SSL/TLS encryption for secure data transmission
• What is the purpose of the HTTP protocol?

  Transferring web pages
• What is the primary purpose of HTTPS?

  Secure communication
• What is the main use of FTP?

  File transfers
• What is FTP primarily used for?

  File transfers
• What is the primary purpose of FTP compared to HTTP?

  File transfers
• What does DNS translate domain names into?

  IP addresses
• Match the DNS server type with its role:

  Root Servers ↔️ Provide initial lookup for TLDs

  Top-Level Domain Servers ↔️ Provide information about second-level domains

  Authoritative Servers ↔️ Provide final IP address for a domain

  Recursive Servers ↔️ Perform full lookup on behalf of client
