Answer is provided in the explanation section
Explanation:
Given data:
Bandwidth of link = 10* 106 bps
Length of packet = 12* 103 bits
Distance of link = 40 * 103m
Transmission Speed = 3 * 108 meters per second
Formulas:
Transmission Delay = data size / bandwidth = (L /B) second
Propagation Delay = distance/transmission speed = d/s
Solution:
Transmission Delay = (12* 103 bits) / (10* 106 bps) = 0.0012 s = 1.2 millisecond
Propagation Delay = (40 * 103 meters)/ (3 * 108mps) = 0.000133 = 0.13 millisecond

Use quotes: Double quotes around a set of words tells gog.le to consider the exact words in that exact order without any change.
Search a web site: allows you to specify that your search results must come from a given website.
Explanation:
If an attacker can see transmitted packets, they will be able to see login credentials and be able to log in to the server. Additionally, the sensitive data in the file will be visible to the attacker. A better way would be to transfer the file using sftp or tftp.

Explanation:
Punch card is the oldest computer storage; followed by tape and then floppy disk. Hard drive goes back as far as floppy but is still in use today. CD/DVD/BR discs are all later storage but are also used for storing music and videos. USB flash, SD card, SSD and cloud storage are the common technologies used today for data storage.
