3.5.4 Network protocols

• Network protocols are a set of rules and standards that define how data is transmitted between devices on a network
• TCP/IP is a common network protocol used for internet communication.

  True
• Match the protocol with its purpose:

  HTTP ↔️ Defines how web browsers and servers communicate

  SMTP ↔️ Enables email transmission between servers

  FTP ↔️ Allows file transfer between computers
• Network protocols ensure devices can reliably exchange information.


  True
• Order the functions handled by network protocols:

  1️⃣ Data Formatting

  2️⃣ Data Timing

  3️⃣ Sequencing

  4️⃣ Error Checking
• The TCP/IP protocol suite is essential for fundamental internet communication
• HTTP defines how web browsers and servers communicate to display web pages.


  True
• Arrange the delivery characteristics of TCP packets:

  1️⃣ Ordered
• UDP is more efficient than TCP for applications that require reliable and ordered data delivery.

  False
• TCP is a connection-oriented protocol that establishes a reliable connection before data transfer
• What is the primary advantage of UDP over TCP?

  Efficiency for time-sensitive data
• HTTP enables web browsing by defining how web browsers and servers communicate.
• What is the purpose of error checking in network protocols?

  Detect and correct errors
• Sequencing in network protocols guarantees data integrity by arranging packets in the correct order.


  True
• Which protocol is responsible for defining a suite of networking protocols that enable internet communication?

  TCP/IP
• UDP is better suited for applications that require reliable and ordered data delivery.

  False
• HTTPS is a secure version of HTTP that encrypts the communication between the client and server.
• What does HTTPS stand for?

  Hypertext Transfer Protocol Secure
• FTP is primarily used for transferring files between computers over a network.

  True
• Arrange the layers of the TCP/IP model in the correct order.

  1️⃣ Application

  2️⃣ Transport

  3️⃣ Internet

  4️⃣ Network Access
• The Internet layer in the TCP/IP model uses the IP protocol for logical addressing and routing.
• Data timing in network protocols manages the exchange of data to prevent collisions and delays
• The TCP/IP protocol suite is the fundamental protocol suite for internet communication
• Network protocols rely on agreed-upon formatting, timing, sequencing, and error checking procedures.


  True
• Match the protocol with its purpose:

  FTP ↔️ Facilitates file transfer between computers

  HTTP ↔️ Defines how web browsers and servers communicate
• SMTP is used for sending email messages between servers.


  True
• Data formatting in network protocols transforms data into a suitable format for transmission
• Error checking in network protocols detects and corrects transmission errors.


  True
• Match the protocol with its purpose:

  TCP/IP ↔️ Fundamental protocol suite for internet communication

  FTP ↔️ Allows file transfer between computers
• TCP is a connection-oriented protocol, while UDP is a connectionless protocol.oriented
• TCP is used for applications like web browsing and file transfer
• What does TCP stand for?

  Transmission Control Protocol
• UDP ensures all data is delivered correctly through error checking and retransmission.

  False
• Match the protocol with its purpose:

  HTTP ↔️ Enables web browsing

  HTTPS ↔️ Provides secure web communication

  FTP ↔️ Facilitates file transfers
• HTTPS encrypts the communication between the client and server to protect sensitive data.


  True
• Data formatting in network protocols transforms data into a suitable format for transmission.
• TCP is a connection-oriented protocol, while UDP is a connectionless protocol.
• What is the primary purpose of HTTP?

  Web browsing
• FTP allows users to manage files on remote servers, such as uploading and downloading them.

  True
• HTTPS is a secure version of HTTP that encrypts the communication between the client and server.
