B1 IP Protocols - correct answer. B1 IP Protocols
B1 (1) What are IP protocols? - correct answer. IP protocols are the set of rules and
standards that govern the communication of data over a network using the Internet
Protocol. The most commonly used IP protocols include IPv4 and IPv6, TCP, UDP and
ICMP.
B1 (2) What is IPv4 and IPv6? - correct answer. IPv4 is the fourth version of the
Internet Protocol, it provides a unique 32-bit address to identify a device on a network.
IPv6 is the sixth version of the Internet Protocol, it provides a unique 128-bit address to
identify a device on a network, it also includes additional features and capabilities than
IPv4.
B1 (3) What is TCP and UDP? - correct answer. TCP (Transmission Control
Protocol) is a transport layer protocol that provides a reliable, ordered delivery of data
over a network. It establishes a connection between two devices before transmitting
data and ensures that all data is received correctly. UDP (User Datagram Protocol) is
also a transport layer protocol but it does not establish a connection before transmitting
data and does not guarantee the delivery of data.
B1 (4) What is ICMP? - correct answer. ICMP (Internet Control Message Protocol) is
a network-layer protocol that is used to send error messages and operational
information about network conditions. It is used to diagnose and troubleshoot network
issues, such as network congestion and errors in IP addresses.
B1 (5) Why is it important to be aware that other IP protocols exist? - correct answer.
Being aware that other IP protocols exist is important because it allows for a deeper
understanding of how networks operate and how different protocols interact with each
other. It also allows for more effective troubleshooting and diagnosis of network issues,
as well as the ability to identify and address security vulnerabilities. Additionally, new
protocols are being developed and introduced, being aware of them can help to future-
proof the security of the network.
