Explain the basic method for implementing paging.

iogann1982 [59]

Answer:

The answer is below

Explanation:

In order to carry out the basic method for implementing paging, the following processes are involved:

1. Both physical and logical memories are broken into predetermined sizes of blocks otherwise known as FRAMES and PAGES respectively

2. During processing, Pages are loaded into the accessible free memory frames from the backing store. The backing store is however compartmentalized into predetermined sizes of blocks whose size is equal to the size of the memory frames

Assume that word is a variable of type String that has been assigned a value. Assume furthermore that this value always contains

Valentin [98]

Answer:

String word = "George slew the dragon";

int pos = word.indexOf("dr");

String drWord = word.substring(pos, pos+4);

System.out.println(drWord);

Explanation:

Assuming dr is always there, we don't have to check the validity of 'pos'. Normally, you would!

The OSI model is a useful tool in troubleshooting a network because it enables you to isolate a problem to a particular software

lutik1710 [3]

Answer:

1) Layer 4, transport

2) Layer 2, datalink

3) Layer 5, session

4) Layer 7, application

Description of Problems are as below:

1) One of your servers has been exhibiting sluggish network performance. you use a network-monitoring program to try to evaluate the problem. You find considerable TCP retries occurring because the server is being overwhelmed by data, and packets are being discarded.

2) You check some statistics generated by a network-monitoring program and discovers that an abnormally high number of CRC errors were detected. (Hint think of the cause of CRC errors).

3) A user is trying to connect to another computer, but the logon attempt is continually rejected.

4) You try to access a Linux server to share files by using NFS. You can communicate with the server, but the shared files don't appear to be available.

Explanation:

OSI Model is a reference model to determine how applications communicate over a network. OSI consists of seven layers, and each layer performs a particular network function. The seven layers are:

Layer 7 - Application.

Layer 6 - Presentation.

Layer 5 - Session.

Layer 4 - Transport.

Layer 3 - Network.

Layer 2 - Data Link.

Layer 1 - Physical.
