What is the bandwidth-delay product for a 50 Mbps channel on a geostationary satellite (assume a RTT of 540 ms)? If the packets

are all 1500 bytes (including headers), how big should the window be in packets to maximize the packet delivery rate?

Answer:

The answer is 2250 packets.

Explanation:

The round trip delay is about 540 millisec, so with a 50 Mbps channel the bandwidth product delay is 27 megabits or 3.375.000 bytes. With packets of 1500 bytes, it takes 2250 packets to fill hte pipe, so the window should be at least 2250 packets.

Race conditions are possible in many computer systems. Consider a banking system with two methods: deposit(amount) and withdraw(
Fittoniya [83]

Answer:

Race Condition is possible if husband and wife both have concurrent functionality.

Explanation:

For eg. if Balance = 3000 and husband withdraws = 1000 then remaining balance is = 2000.

One the other hand if balance is 3000 and wife deposits =1000 then remaining balance is 4000

we can see that there is inconsistency that is not acceptable.

To solve the problem mostly we are using Peterson's Algorithm

Account can be used for husband and wife,

int flag = 0

boolean account

1 :Husband

do{

account[i] =TRUE;

flag=(i+1)%2

while (account [(i+1)%2] && turn =(i+1)%2;

withdraw();

account[i] = FALSE

(remainder)

} While (TRUE);

This process can be repeat with (Wife)  where i will be replaced by j ,i=0 or 1 and j =1 or 0

  • flag identify which is going to access the bank account
  • account make sire that 2 users are mutually exclusive

Proved the race condition is prevented

You want to transfer a document from one computer to another, and you want the document to be encrypted. The destination compute
Alex_Xolod [135]

Answer:

Check the explanation

Explanation:

This document transfer ought to work smoothly. Due to the IEEE standards and Principles, the presentation layer is expected to encrypt/decrypt the data on both part of the network. The session layer creates a mutual coordination among the applications while the transport layer is there to ensures delivery. Immediately the segments hit the network, routers control and handle the routing process of the packets to the distant end. Layers 6, 3 & 1 are straightly involved in the italicized parts of the question; however, the entire layers play a role when looking at the transfer as a whole.

What is a lease? AA contract outlining the terms of a mortgage. BA contract outlining the terms under which a landlord agrees to
Lesechka [4]

B. A contract outlining the terms under which a landlord agrees to rent property to a tenant.   
A lease is where you arrange to use someone else's property, generally in exchange for money. The ownership of the property remains with the other entity. So with that in mind, let's look at the options.  
A. A contract outlining the terms of a mortgage.  
* This is a contract arranging for the transfer of ownership of property from one entity to another. So this is not a lease and is a bad choice.  
B. A contract outlining the terms under which a landlord agrees to rent property to a tenant.  
* This does meet the definition of a lease. You rent and therefore use someone else's property, but the ownership of the property remains with the landlord. So this is the correct choice.  
C. A loan from a bank used to rent a home. 
 * This does not meet the definition of a lease and is therefore a bad choice. 
 D. A loan from a bank used to buy a house. 
* This also does not meet the definition of a lease and is therefore a bad choice.
