This Print Screen key is used to take the screenshots of all that is appearing on the screen, and this can then be pasted in paint and saved in some location of the computer.
The Home key takes the cursor from the current position to the top left, or the start of the file.
Shift: There are two shift keys. And they are used to print the character in the capital. And when the caps lock is busy it can be used to print in lower case. It is also used together with arrow keys to select a part of the text.
Tab: This key moves the cursor from the current location to the location which we know as tab stops ( and the very next one).
Pg Up: The page up is being used for scrolling up, and the distance to which limit the scrolling will take place depends upon the application you are working on.

Answer:
The answer is "2".
Explanation:
In the given question some information is missing, that is "The propagation time for satellite to earth" which is "270 milliseconds" so, the description to this question can be defined as follows:
Given values:
Bandwidth = 64 kbps
Data frames = 512 bytes
Propagation Time (tp ) =270 ms
Change Bandwidth kbps to bps:
1 kb= 1024 bytes
calculated bandwidth= 64 kbps = 64×1024 bps = 65536 bps
1 bytes = 8 bits
512 bytes = 512 × 8 = 4096 bits
Frame length = 4096 bits
Formula
Transmission time (Tt) = Frame length /Bandwidth
Window size = 1+2a
where a = Propagation time/Transmission time
Calculate Transmission time:
Transmission time (Tt) = 4096 / 65536
Transmission time (Tt)= 625 m.sec
Calculate Window size:
Window size = 1+2(270/625)
Window size
= 1+2(0.432)
Window size
= 1+0.864
Window size = 1.864
Window size
= 2
Answer:
b. Using either the read-write or read-only community string.
Explanation:
The SNMP agent on a router authenticates any SNMP Get requests received from the NMS using either the read-write or read-only community string.
In the SNMPv2c, if the NMS sends either the read-write or read-only community string requests, SNMP Get requests will be allowed.
