Understanding the use of common protocols

• Communication protocols are sets of rules that govern how data is transmitted over a network.
• Arrange the key functions of communication protocols in the correct order:

  1️⃣ Data format and structure standardization

  2️⃣ Error detection and correction

  3️⃣ Authentication and security

  4️⃣ Connection management between devices
• IP is responsible for ensuring reliable data delivery.

  False
• What is the fundamental protocol suite that enables communication across the internet and modern computer networks?

  TCP/IP
• Which protocol transfers web pages securely using SSL/TLS encryption?

  HTTPS
• What are communication protocols used for in computer networks?

  Governing data transmission rules
• What is one crucial role of protocols in computer networks?

  Standardizing data format
• Match the protocol with its typical application:

  Ethernet ↔️ Desktops and routers

  Wi-Fi ↔️ Laptops and IoT devices

  Bluetooth ↔️ Headphones and keyboards
• IP is responsible for addressing data packets and routing
• HTTPS ensures data encryption during web page transfers.

  True
• IP is responsible for addressing data packets and routing
• HTTP transmits data in plain text.


  True
• Match the protocol with its security level:

  HTTP ↔️ Not secure

  HTTPS ↔️ Secured with SSL/TLS
• What is the security level of FTP by default?

  Not secure
• What is the primary function of SMTP?

  Sends emails
• Match the protocol with its function:

  HTTP ↔️ Transfers web pages

  SMTP ↔️ Sends emails

  FTP ↔️ Transfers files

  HTTPS ↔️ Transfers web pages securely
• Match the wired and wireless protocol with its characteristics:

  Ethernet ↔️ High speed, reliability

  Wi-Fi ↔️ Mobility, wide availability

  Bluetooth ↔️ Short-range connectivity, low power consumption
• The TCP ensures reliable data delivery by providing error checking and flow control mechanisms.
• What is the primary responsibility of the IP (Internet Protocol) component of TCP/IP?

  Addressing and routing data packets
• HTTP is a protocol used to transfer web pages but is not secure by default.
• Wi-Fi has a shorter range than Ethernet but offers greater mobility.


  True
• What is the fundamental protocol suite that enables communication across the internet and modern computer networks?

  TCP/IP
• Which protocol uses SSL/TLS encryption to secure data transmission?

  HTTPS
• What type of security does HTTPS provide?

  SSL/TLS encryption
• What does HTTP stand for?

  Hypertext Transfer Protocol
• HTTPS is the secure version of HTTP
• FTP transmits data and login credentials in plain text by default.


  True
• SMTP is secure by default.

  False
• TCP/IP is inherently secure without additional encryption.

  False
• TCP/IP is not inherently secure, unlike HTTPS, which uses SSL/TLS encryption.
• TCP ensures reliable data delivery by providing error checking and flow control mechanisms.
• TCP/IP is inherently secure.

  False
• Communication protocols ensure that devices can communicate effectively by establishing a standard language.

  True
• Order the following wired and wireless protocols from fastest to slowest bandwidth:

  1️⃣ Ethernet

  2️⃣ Wi-Fi

  3️⃣ Bluetooth
• TCP/IP is not inherently secure, unlike protocols like HTTPS, which use SSL/TLS encryption.
• TCP/IP is inherently secure.

  False
• IP is responsible for addressing data packets and routing
• Which protocol is secured with SSL/TLS encryption?

  HTTPS
• What is the security level of HTTP by default?

  Not secure
• What does FTP allow users to do?

  Transfer files
