Answer:
This is important to understand the basic ways to store pictures and video in a computer because both of them consume a relatively large storage spaces in a the computer compared with normal text files.
Explanation:
Nowadays, many computers shipped with a SSD drive (Solid State Drive) with only around 256 - 512 Gb. With this capacity, the storage spaces left to store the pictures and video are very limited after installation of the essential software.
One common way to store pictures and video is to save them at an external hard drive. Another option is the cloud storage service such as Google Drive, Google Photo etc. These storage mediums obviate the need to store those media files into the local computer machine.
The process of Starting up a computer is referred to as booting
Answer:
An answer to this question is given below in explanation section.
Explanation:
The given question is incomplete. First, we write the complete question that is:
Suppose Client A initiates a Telnet session with Server S. At about the same time, Client B also initiates a Telnet session with Server S. Run telnet in a terminal and capture the traffic on Wireshark. For example, open a telnet session using this command: "telnet cs537.cs.csusm.edu". What are the source and destination port numbers for the following items?
- the segment sent from A to S.
- the segment sent from B to S.
- the segment sent from S to A.
- the segment sent from S to B.
- if A and B are different hosts, is it possible that the source port number in the segments from A to S is the same as that from B to S?
- how about if they are the same host?
Answers
Source Port Numbers Destination Port Number
- A -> S 1467 23
- B -> S 1513 23
- S->A 23 1467
- S->B 23 1513
- Yes, it is that the source port number in the segement from A to S is the same as that from B to S. In short, there is no relationship between port numbers on different hosts
- no, a port number identify UNIVOCALLY a process.
Assuming this is only and external hard drive and there is no operating system installed on it, first, if you can't seem to access the drive, format it to a format your computer should be able to read. Then, I'd recommend organizing everything. Add folders for each class you take, and inside those add folders for actual homework and one for projects. You can add a miscellaneous folder if you'd like, for any extra files you might need to use.
