Answer: d. should be lowercase.
Explanation:
ID attributes are case sensitive for the most part - DOM and Java Script - which means that the ID attribute does not always have to be lowercase.
It can be uppercase as well. ID attributes can also start with a number and as of HTML 5 can start with a special character as well. Finally, the ID attribute must always be unique within each document.
Answer: Registers
Explanation:
Registers are small storage locations identified by different types of registers. The function of the register is to provide data for immediate processing to the CPU. These registers hold data temporarily and provide easy access of data to the processor.
The answer is D. The SUM function lets you add all the values along the specified cells. To use the SUM function, you type the equal symbol and the word "sum" then a parenthesis. Inside the parenthesis are the cells you want to add-up. Specify it from the first cell to the last. Add a colon in between to two cell locations. So the right formula to input in finding the sum of all the values from A1 to A10 is =sum(A1:A10).

Answer:
Wavelength Mismatch
Explanation:
Optical fiber cables are used because they have lowest attenuation(loss of signal strength).
Attenuation is directly proportional to wavelength.
According to me this issue is most likely caused by Wavelength mismatch.If the wavelength of the signal is high then there is more attenuation in that signal.
