Answer:
A. a clear central message.
When creating a presentation on basically anything, there should always be a clear central message. The purpose of most presentations are to give information on what the presenter would like to convey to the audience members. Without a clear central message, the audience members would be lost and the presentations purpose will not be fulfilled.
first learn the basics about the computer than just slowing move into it you feel?
You just have to put it into a computer and a file is gonna come up
Answer:
C. Ethernet over multi mode fiber .
Explanation:
Given that the distance to be covered is 1 km. Multi-mode optic fiber is best suited for short distances of up to 2 km and can withstand harsh environments with less signal attenuation. Single mode fiber is best suited long distance of up to 200 km or more and is expensive as compared to multi-mode fiber Ethernet over twisted pair is best for indoor use and can only cover very short distances. Although UTP and STP are relatively cheap they cannot withstand harsh environments without great signal loss.
A single expression that will return true if the lower four bits of x are the same as the lower four bits of y is; (x & 0x0F) == (y & 0x0F)
<h3>How do you write single expression programs?</h3>
There are different methods of writing programs such as python and others. However, in this case, it is pertinent to know that this compiler that will return true if the lower four bits of x are the same as the lower four bits of y doesn't accept binary constants and as such we will use hexidecimal instead. For example; for 0b00111111, we will use 0x3F.]
Thus, using that same concept above, the single expression that will return true if the lower four bits of x are the same as the lower four bits of y is; (x & 0x0F) == (y & 0x0F)
