Solution:
The common information listed under the ip section of pdu details as compared to the information listed under the osi model tab is Packet Tracer.
This simulation activity is intended to provide a foundation for understanding the TCP/IP protocol suite and the relationship to the OSI model. Simulation mode allows you to view the data contents being sent across the network at each layer. As data moves through the network, it is broken down into smaller pieces and identified so that the pieces can be put back together when they arrive at the destination. Each piece is assigned a specific name (protocol data unit [PDU]) and associated with a specific layer of the TCP/IP and OSI models. Packet Tracer simulation mode enables you to view each of the layers and the associated PDU. The following steps lead the user through the process of requesting a web page from a web server by using the web browser application available on a client PC. Even though much of the information displayed will be discussed in more detail later, this is an opportunity to explore the functionality of Packet Tracer and be able to visualize the encapsulation process.
This is the required answer.
Answer:
Total unit of work required is 1019 units.
Solution:
As per the question:
Initial capacity = 100
On each expansion 50 is added to the present capacity.
Now,
Work done required in addition of 1000 items = 1000 unit
No. of times there is a need for the allocation of a new Array is given by:
We know that:
On addition of 101th element it expands from 100 to 150
On addition of 151st element it expands from 150 to 200 and so on till
On addition of 951st element it expands from 950 to 1000
Now,
For an array of 100 size - 1 for initial allocation.
Therefore, total work done is given by:
W = 
True, but the only way to get these constant place holders is of you program them in, in other words you have to tell the computer that you want them.
