Network Layer Flashcards
is responsible for the source-to-destination delivery of a packet, possibly across multiple networks (links).
Network Layer
oversees the delivery of the packet between two systems on the same network (links).
Data Link Layer
ensures that each packet gets from its point of origin to its final destination
Network Layer
one of the functions of the network layer is to provide?
routing mechanism
is a 32-bit address that uniquely and universally defines the connection of a device (for example, a computer or a router) to the Internet.
IPv4 address
how long is an IPv4 address?
32 bits
is the total number of addresses used by the protocol.
address space
IPv4 uses 32-bit addresses, which means that the address space is?
2^32 or more than 4 billion.
There are two prevalent notations to show an IPv4 address:
Binary Notation and Dotted Decimal Notation
In what notation does the IPv4 address displayed as 32 bits?
Binary Notation
In binary notation, how do you refer each octet?
byte
What are the other names of an IPv4 address?
32-bit address or 4 byte address
To make the IPv4 address more compact and easier to read, Internet addresses are usually written in what?
decimal point separating the bytes.
IPv4 addressing, at its inception, used the concept of classes. This architecture is called?
classful addressing
In classful addressing, the address space is divided into five classes:
A, B, C, D, and E
Class A: First Byte
0-127
Class B: First Byte
128-191
Class C: First Byte
192-223
Class D: First Byte
224-239
Class E: First Byte
240-255
