An prototype mean an working model used to test a design
Answer:
The correct answer to the following question will be "Safe and relatively low data and voice transmission".
Explanation:
Frequently, the word narrow band corresponds to ultra-high-frequency, S and L bands where the reasonable range is restricted compared to the bands of high-frequency.
- It is desirable throughout the extremely-high-frequency, L-, including S-bands due to the beneficial propagation characteristics of the wavelengths.
- Narrow band Satellite systems facilitate the efficient delivery of both wireless mobile networks at comparatively low bandwidths.
So, By the safe and low data transmission, it's the right answer.
Answer:
Rootkit.
Explanation:
Rootkit is a collection of software tools,mostly malicious.These are mostly used by hackers to obtain administrator permission to a computer by masking intrusion.
Root-kit is made from two word Root and kit.Where root refers to the name of privileged account on an operating system that is somewhat like unix and KIT refers to the tools used.
Answer:
12.1 seconds
Explanation:
Step 1:
Assuming the following data :
N: Size of packet = 30 Mb
T: Transmission rate = 10 Mbps
C: Speed of light in copper = 2 * 10^8 m/s
L: Length of link 5000 km
Step 2:
Calculation of the Transmission delay and the Propagation Delay
Transmission delay = 
= 
= 3s
Propagation delay = 
= 
= 0.025s
Step 3:
Calculation of the end-to -end delay
The end-to-end delay = 4*(Transmission Delay+Propagation Delay) = 4*(3+0.025) = 12.1 seconds
