Bits & Bytes: Week 2, I - the Network Layer Flashcards
A ___ address changes depending on your LAN; a ___ changes depending on which device you use
IP; MAC
ACRONYM: ARP
Address Resolution Protocol
ACRONYM:
DHCP
Dynamic Host Configuration Protocol
ACRONYM:
QOS
Quality of Service
ACRONYM:
TTL
Time to Live
Each network package contains a payload that encloses all necessary information, protocols, and data for each succesive network layer. What is this process called?
Encapsulation
How does a node find the MAC address of a device that doesn’t have an entry in its ARP table?
It sends a broadcast Address Resolution Protocol message to the MAC broadcast address and the device with the matching address responds with the data it needs
How long is an IP address in bits? In octets?
32 bits; 4 octets
How many bytes is the minimum for an IP header?
20 bytes
If the first bit of a binary IP address is 0, which IP class does that address belong to?
IP Class A
What would the following binary sequence look like as an IP address:
00001100 . 00100010 . 00111000 . 01001110
12.32.56.78
Technology that allows communication across very long distances almost instantaneously is part of this layer.
The Network Layer
This class of IP address contains the network ID in the first two octets and the host ID in the last two octets
Class B IP Address
This class of IP address contains the network ID in the first three octets and the host ID in the last octet
Class C IP address
This field contains a 16 bit number used to group (but not necessary order) separate IP Datagrams together that are part of the same transmission
the Identification Field
This field contains values needed by the receiving end to correctly order a fragmented datagram
the Fragment Offset Field
This field is used to set special characteristics for datagrams and is primarily used for testing purposes
the IP Options Field
This field of an IP Datagram Header can be used to specify details about Quality of Service technologies
the Service Type Field
this is a list of IP address and the MAC addresses associated with them
Address Resolution Protocol Table
This is a way of defining how the global IP address space is split up
Address Class System
this is the process of taking a single IP datagram and splitting it up into several smaller datagrams
fragmentation
This protocol is used to discover the hardware address of a node within a certain IP address
Address Resolution Protocol
