Answer:
Following are the solution to the given question:
Explanation:
The common folder called Report has also been shared. Writing access to a shared folder was given to management group members. Mark is a member of a group of managers. We can access the files within your reporting directory, but you really should not access the Confidential.xls file. We want to add Mark Mangum to our ACL files using Deny permissions on Confidential.xls.
Answer:
okay
so what is it what is your question..
Answer: object that persist set of values and operations as behavior
Explanation: Abstract data types(ADT)are those object value which are dependent upon the collection of the values and collection of the operations.The organization of the data object is not specified in ADT but the operations that are to be carried out are defined in it.
The implementation individuality displayed by the ADT and hiding of the representation or design makes it abstract.
Answer:
a) 500 Kbps b) 64 sec c) 320 sec
Explanation:
a) We define the throughput of a network, as the actual maximum transmission rate that the network is able to deliver, which in this case is equal to the lowest transmission rate of any of the links that the traffic must go through:
R1 =500 kbps
b) If the file size is given in bytes, and we have the throughput in bps, we need to convert to bits first, as follows:
4*10⁶ bytes * (8 bits/byte) = 32*10⁶ bits.
The time needed to transfer the file, will be given by the quotient between the file size and the throughput, as follows:
t = 32*10⁶ bits / 500*10³ bits/sec = 64 sec
c) If the transmission rate R2 is reduced to 100 kbps, R2 becomes the lowest transmission rate in the network, so it becomes the new throughput.
So, the time needed for the same file to be transferred to host B is as follows:
t= 32*10⁶ bits / 100*10³ bits/sec = 320 sec
