Microsoft windows was his first
Answer:
B.
Explanation:
A. is not the correct answer because that is called a LAN cable (ethernet)
C. is not correct because it has nothing to do with text messages or printing
D. is called a Bus, and isn't the right answer either
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
Hey there!
- The word "<u>verb</u>" simply means <em>'description of an action, assert, or event that is made into the main purpose of your predicate in your judgement' </em>
- Now that we have the definition of the word verb we can answer your question
- "<em>Has</em>" is past tense but it is THIRD person present
- "<em>Have</em>" is when you own something
<h2>Answer:
HAS ✅</h2>
BECAUSE "I SAW last night"
Note: usually people read the sentence to themselves until it makes easier sense to them or use context clues in the sentence to answer the particular question(s)
Good luck on your assignment and enjoy your day!
