Answer:
Wow, that’s pretty good question.
I would probably get a vpn because it gives free secure WiFi. And it’s most reliable.
Hope I helped!
Answer:
Monitor
Power supply
Explanation:
Monitor is the display unit of the computer. It carries capacitors which are charged and helps in electronic display.
Power supply is the unit which converts the AC electric supply to DC supply. It utilizes the capacitors to perform this function
While the hard drive and video card does not contain any capacitors.
Answer:
Cloud Computing
Explanation:
Cloud Computing is basically an infrastructure to deliver various computing resources and services to the users online (via Internet). These resources include networks, applications, servers, databases, software, storage etc.
These services are mostly utilized by organizations for recovery and backup of data, using virtual hardware and other computing resources such as desktops, memory etc. Cloud computing is also used for developing software, for securing data by providing with access control and for storing bulk of data.
The benefits of cloud computing are as following:
Because of cloud computing the customers do not have to buy hardware or install software on their computer which might be very costly to maintain and update. Servers and data centers are provided by cloud service providers and experts are available for managing the services and resources.
These services are scalable and can be adjusted as per the users requirements.
Cloud computing offers a variety of protocols, tools, and access controls that improve security and protects confidential data, applications, and networks against security threats and attacks. It also provides with data backup, disaster recovery.
Answer and Explanation:
Given data:
Distance (D) = 40 KM
Speed of light in the fiber =Distance/ speed of light in the fiber
a) Delay (P) = Distance/ speed of light in the fiber
= (40,000 Meters/2×108 m/s)
=( 40×103 Meters/2×108 m/s)
Propagation delay (P) = 0.0002 seconds or 200 microseconds
b)
if propagation delay is 0.0002 Seconds roundup trip time (RTT) will be 0.0004 Seconds or 400 micro Seconds
Essentially since transmission times and returning ACKs are insignificant all we really need is a value slightly greater than 0.0004 seconds for our timeout value.
c)
The obvious reasons would be if the data frame was lost, or if the ACK was lost. Other possibilities include extremely slow processing on the receive side (late ACK).
Or Extremely Slow Processing of the ACK after it is received back at the send side.
Answer:
I think is None of this ,
