Assignment#01(GRADED)

Total marks = 20

                                                                                       Deadline Date =18-May-2016

 

Please carefully read the following instructions before attempting the assignment.

Assignment Guidelines:

It should be clear that your assignment would not get any credit if:

  • The assignment is submitted after due date.
  • The submitted assignment does not open or file is corrupt.
  • The assignment is copied. Note that strict action would be taken if the submitted assignment is copied from any other student. Both students will be punished severely.

 

1)      You should consult recommended books to clarify your concepts as handouts are not sufficient.

2)      You are supposed to submit your assignment in .doc or docx format. Any other formats like scan images, PDF, Zip, rar, bmp etc will not be accepted.

3)      You are advised to upload your assignment at least two days before due date.

Important Note:

Assignment comprises of 20 Marks. Note that no assignment will be accepted after due date via email in any case (whether it is the case of load shedding or emergency electric failure or internet malfunctioning etc.). Hence, refrain from uploading assignment in the last hour of the deadline, and try to upload Solutions at least 02 days before the deadline to avoid inconvenience later on.

The objective of this assignment is:

  • To understand Addressing scheme in the context of WAN

 

 

 

 

Task 1:

IP Addressing scheme is used throughout internet for communication between different devices connected across the globe. Physical addressing is also an option that can be used in order to provide communication between different devices connected to the internet. According to your view, what problems exists because of which physical addressing is not used across the WAN for communication between different devices. Give reasons to support your answer.

Task 2:

You are given the following frame (001011000101) to be transmitted across the Ethernet network. Encode the given steam of bits using Manchester encoding scheme.

 

 

 

Good Luck

task 2 is tarha karna hay kia

Kis trha?

MAC address physical address ko kahtay han kia

Yes dear, the physical address is also called the mac address

and the Manchester encoding is in the graphical form..

Best of Luck!

Please Discuss here about this assignment.Thanks

Our main purpose here discussion not just Solution

We are here with you hands in hands to facilitate your learning and do not appreciate the idea of copying or replicating solutions.

A media access control address (MAC address), also called physicaladdress, is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi.

MAC addresses are a low level component of an Ethernet network (and some other similar standards, such as WiFi). They allow a device to communicate with a machine on the local physical network (LAN), and cannot be routed across the Internet - because physical hardware might in theory be plugged in anywhere in the world.

By contrast, IP addresses cover the whole internet, and routers use them to figure out where to send data even if it needs multiple hops to reach its destination – but they aren't helpful in interfacing with the physical hardware on your local network.

If we ever found a better standard than Ethernet, it might not use MAC addresses but IP traffic from the internet could still flow across it, even if other people on the internet had never heard of it.

If we ever found a better standard than IP (for example IPv6 if all the IPv4 addresses ran out), most Ethernet hardware could carry the new kind of traffic without modification – and a simple software/firmware update would fix most of the rest.

kia hamain physical address ka name batana hay jo use nhn hote hay wan main devices se communication ke leye?

Task No 2 Kis tarha kerna hy Please reply....!

Agar to graphical main kerna hy to kis software main design kerain?

Use any software to draw diagram. You can use MS Word, Visio or Paint.

Yup Done...

THanks
