Front 30

What does UDP stand for?

Back 30

User Datagram Protocol

Front 31

Which is used more commonly TCP or UDP? Which is faster? Why?

Back 31

UDP. UDP is faster because it is not a connection-oriented protocol, it is a connectionless protocol.

Front 45

What is assigned to each node on a network to uniquely identify each host in layer 3?

Back 45

The IP address.

Front 46

What from layer 3 relies on several routing protocols to find the best route for a packet to take to reach its destination.

Back 46

Front 47

What layer provides interfaces to software that enables it to use network services via an API?

Back 47

Application layer

Front 48

What does API stand for? What is it?

Back 48

Application Program Interface. It is a set of instructions that allows a program to interact with the Operating System.

Front 49

How many parts does a MAC address have? What are they? How many bits are each part?

Back 49

Two parts, the OUI (Organizationally Unique Identifier) or block ID or company-ID, and the device ID.

Front 50

How many bits are each part of the MAC address?

Back 50

24 bits each. 48 in total.

Front 51

How many bits does an IPv6 address have? How many blocks of what is it?

Back 51

It has 128 bits, that is 8 blocks of hexadecimal numbers separated by colons.

Front 52

Back 52

A specific single node on a network

Front 53

What is a multicast address on an IPv6 Address?

Back 53

An address where packets are delivered to all nodes on a network.

Front 54

What is an anycast address on an IPv6 Address?

Back 54

An address that can identify multiple destinations, with packets delivered to the closest destination.

Front 55

How are IPv4 and IPv6 Addresses different?

Back 55

IPv4 addresses only allow for 1,500 MB to flow at once, IPv6 allows for jumbo frames, at 9,000 MB to flow at once. IPv4 has little to no security, IPv6 has IPsec. IPv6 is much more expensive.
