Charles is having a lot of problems with errors in a very complicated spreadsheet that he inherited from a colleague, and he turns to another co-worker, Seymour, for tips on how to trace errors in the sheet. Seymour tells Charles that all error values begin with the same symbol, so they can be easily identified as errors.
The symbol is A)#.
Explanation:
- An error is something you have done which is considered to be incorrect or wrong, or which should not have been done.
- Generally errors are classified into three types: systematic errors, random errors and blunders
- Error values begin with the same symbol as they are easy to identify. Once an error is identified, it can be corrected.
- Error correction is the process of detecting errors in transmitted messages and reconstructing the original error-free data. Error correction ensures that corrected and error-free messages are obtained at the receiver side.
- Error Correction can be handled in two ways: Backward error correction: Once the error is discovered, the receiver requests the sender to retransmit the entire data unit. Forward error correction: In this case, the receiver uses the error-correcting code which automatically corrects the errors.
Answer:
You must evaluate information
Explanation:
The first step to thinking critically is to accept information only after evaluating it. Whether it's something read or heard, critical thinkers strive to find the objective truth. In doing this, these employees evaluate by considering possible challenges and solutions. This process of vetting new information and considering outcomes is called evaluation.
Answer:
Attenuation is the one-word answer which is the correct answer for the above question.
Explanation:
Attenuation is a concept which told about the barrier, which is used to stop the signals in the connected network systems. Attenuation can be a form of any type of barrier like weak signals, or because of long-distance.
Following are the example which is in the form of attenuation--
- Noise
- The distance can also be a problem for weak signals.
- Hacker also disestablished the network signals.
- The physical objects.
Hence the attenuation can be formed by any of the barriers of signals, like physical obstruction, longer distance, and radio inference.
Full-Duplex is data flow that can travel in two directions at the same time.
Half-Duplex is data flow that can travel in two directions but not at the same time.
Simplex is data flow that can only travel in one direction.
Answer:
B.
Explanation:
Computer manual is the user guide that comes along with the computer set to inform the users about the functions, ways to assemble the parts, and so on.
The user manual consists of guide for the users specially for electronic products such as computers, refrigerators; softwares, and so on. These manuals are written by technical writers, programmers, etc.
<u>In the given scenario the technician needs to refer to computer manual to know the meaning of the lights on the backside of the computer.</u>
So, the correct answer is option B.
