Answer:
A) 2.56 ms
B) 128 μs
Explanation:
Time for Bus cycles = 500 ns
Transfer of bus control = 250 ns
I/0 device data transfer rate = 50 KB/s
Data are transferred at : 1 byte at a time
A) Determine how long the device tie up the bus when transferring a block of 128 bytes
Block size to be transferred = 128 bytes
Bandwidth = 50 KB/s
data transfer = (Block size ) / ( Bandwidth)
= ( 128 * 8 ) / ( 50 * 10^3 * 8 )
= ( 1024 ) / ( 50 * 10^3 * 8 )
= 2.56 ms
To determine the actual transfer time we have to add up the transfer time for the bus control in both directions :
2.56 ms + 500 ns = 2.56 ms. this is because 500 ns is not a significant value
B) cycle stealing mode
In this mode each byte is transferred at a time and The total transfer time needed for the bus control in both directions will be double the total time i.e 2 * 500 ns = 1000 ns. because additional control time of 250 ns is required at both ends
since 1 byte is transferred at a time , 1 byte will be transferred in 1 μs
128 bytes = 128 * 1 μs = 128 μs
Hey there,
Your question states: <span>Which careers have the highest minimum experience requirement?
I believe that your correct answer would be "</span>network administrator". Now the reason why this would be the answer is not just because I say that, it's because being a administrator does not need high experience requirement. It's a basic thing to do. This is why being a "network administrator" would be <span>the highest minimum experience requirement.

Answer:
The CA's public key must validate the CA's digital signature on the server certificate.
Explanation:
Answer: Detect user agent
Explanation:
Although is not recommended to use this method, as is better for usability and accessibility the implementation of feature detection and Progressive enhancement in the modern web, it is possible to detect the browser by sniffing the user agent string to detect which browser is being used. The part you would look to distinguish each browser is found in the Rendering Engine and the values you will get are: Gecko, Webkit, Presto, Blink.
