  • What is a protocol?

  • A protocol is a set of rules that allows devices on a network to communicate and share data.

  • What does TCP/IP stand for?

  • Transmission Control Protocol/Internet Protocol.

  • What is the Link Layer responsible for in TCP/IP?

  • It handles the physical transmission of data on a local network.

  • What technologies are used in the Link Layer?

  • Technologies like Ethernet and Wi-Fi.

  • What is a MAC address and why is it important?

  • A MAC address is a unique identifier for a device’s network interface, crucial for data transmission in the Link Layer.

  • What is the Internet Layer responsible for?

  • The Internet Layer handles data addressing and routing across networks.

  • What is the role of routers in the Internet Layer?

  • Routers forward data between different networks in the Internet Layer.

  • What does ARP stand for and what does it do?

  • Address Resolution Protocol, which translates IP addresses to MAC addresses.

  • Is IP reliable or unreliable?

  • IP provides unreliable, connectionless data delivery.

  • What does the Transport Layer manage?

  • The Transport Layer manages multiple connections between devices.

  • What does TCP stand for and what does it do?

  • Transmission Control Protocol; it ensures reliable, connection-oriented data delivery.

  • What does UDP stand for and how does it differ from TCP?

  • User Datagram Protocol; it is faster but less reliable than TCP, used for time-sensitive tasks like video or voice.

  • What is the role of the Application Layer in TCP/IP?

  • It manages specific tasks like web browsing (HTTP), email (SMTP), and file transfer (FTP).

  • What is an IPv4 address?

  • An address used in TCP/IP networks to identify devices and route data.

  • How long is an IPv4 address?

  • IPv4 addresses are 32 bits long.

  • What is dotted decimal notation?

  • A method to represent IPv4 addresses as four decimal numbers separated by periods.

  • What is a network prefix in IPv4?

  • It separates the network ID from the host ID in an IPv4 address.

  • What is a subnet mask?

  • A subnet mask is used to divide an IP network into smaller subnets.

  • What is slash notation and how is it used?

  • It is a notation to represent the length of the network prefix (e.g., /24).

  • What are private IPv4 address ranges?

  • Class A: 10.0.0.0 to 10.255.255.255; Class B: 172.16.0.0 to 172.31.255.255; Class C: 192.168.0.0 to 192.168.255.255.

  • What does NAT stand for and what is its role?

  • Network Address Translation; it translates private IP addresses to public ones for Internet communication.

  • What is a default gateway?

  • It is the IP address of a router that forwards packets to other networks.

  • What is DHCP and why is it important?

  • Dynamic Host Configuration Protocol; it automatically assigns IP addresses, subnet masks, gateways, and DNS addresses.

  • What is APIPA?

  • Automatic Private IP Addressing; it assigns a random IP from the 169.254.x.x range if DHCP fails.

  • What is the difference between static and dynamic IP addressing?

  • Static addressing is manual, while dynamic addressing uses DHCP for automatic configuration.

  • How are public and private IP addresses different?

  • Public IPs are globally unique and routable, while private IPs are only used within private networks.

  • What is an IPv6 address?

  • A 128-bit address used in IPv6 networks to identify devices.

  • How long is an IPv6 address?

  • IPv6 addresses are 128 bits long.

  • How are IPv6 addresses written?

  • IPv6 addresses are written in hexadecimal and divided into eight groups separated by colons.

  • What is SLAAC in IPv6?

  • StateLess Address Auto Configuration; it allows IPv6 devices to automatically assign addresses without a DHCP server.

  • What is dual stack in relation to IPv6?

  • Dual stack refers to devices running both IPv4 and IPv6 simultaneously.
