Microsoft Word - Tute1.docxAssignment 1    1. List the layers of the OSI model and the TCP/IP protocol suite (the Internet Model)  2. How do the layers of the OSI coelate to the layers of the TCP/IP protocol suite?  3. Which layers of the TCP/IP protocol suite are the network support layers and which layers are the user support layers?  4. What is data encapsulation (with respect to Questions 1-3)?  5. What are the responsibilities of the Data Link layer?  6. What is the difference between Network layer and Transport layer delivery?  7. If the Data link layer can detect eors between hops, why do you think we need another mechanism at the Transport layer?  8. What are the responsibilities of the Network layer?  9. What are the responsibilities of the Transport layer?  10. What is the difference between a port address, a logical address and a physical address?  11.

ASSIGNMENT 2
Question 1
	In the class full addressing the IP address are directly isolated which is divided into class A, B, C, D and E. Class A,B, and C are utilised in the allocation of the address, class D is for the multicast and class E is reserved. 
	The classless address is also knows the classless inter domain routing. It directly uses and approach which is linked to the dispense and determine the internet address which should be utilised in the space steering. 
Question 2
	The block in the class A is very much big for almost any organisation. This directly means that most of the address in the class A are directly unexploited (Dawadi, Joshi & Khanal, 2015). The class A has a subnet of 24bits engaging more than 17million individual devices and most of the organisation has a faction of this number of devices. 
Question 3
In an IP address, there are two modules, which is the host address and the network address. A mask directly separates the IP address into the host address and the network (). The concept can be very much be beneficial for the sector of identification of a network address which is present and currently functional. 
Question 4
The network address is the first address which is generated in the sector which directly lineks the IP address of the network which is connected in the sector of the working and the propagation of the message. 
Question 5
A network subnet can be considered as a logical subdivision of an IP address. The computers that directly fit to a subnet are addressed with an equal most significant bit group in their IP address. 
Question 6
NAT stands for Network address translation. It is a method, which is used for the concept of remapping one of the IP address space to another by means of modifying the network address information in the IP header of the packet while they are transmitted across a routing traffic device. 
NAT directly helps the user to engage in a large set of addresses internally and one address or a small set of address externally. The traffic uses large set when outside and small set when they are inside.
