Answer:
The receiver will not detect the error.
Explanation:
The byte sent by transmitter: 10101010
The byte received by receiver due to channel noise: 10011010
If you see the bold part of the both sent and received bytes you can see that the number of bits changed is 2.
The two communicating devices are using a single-bit even parity check. Here there are two changed bits so this error will not be detected as this single bit even parity check scheme has a limit and it detects the error when the value of changed bit is odd but here it is even.
This parity scheme basically works well with the odd number of bit errors.
Answer:
D. infrared.
Explanation:
Wireless technology for communication uses electromagnetic wave to transmit signals between location. It eliminates the need of cables for connecting network devices.
In previous wireless technology implementation, Infrared rays were used (in tv remotes), which needed to be in the line of sight to its destination. Although it was fast, it has many limitations for a long-haul transmission like its short transmission range, easily blocked by objects and its uni-directional properties.
Answer:
Well, this code would box the whole body of an html document. by using the relative value for position, you are telling it to position relative to its normal position, which the top left corner is at (0,0). by using left: 50px, you are telling the box to set the left margin edge to 50px and by using top: 50px, you are telling it to set the top margin edge to 50px. by doing this shifting, the top left corner of the box, which is at (0,0) would be positioned at (50,50)
