A PCM system consists of a PCM encoder (transmitter) and a PCM decoder (receiver). The essential operations in the PCM transmitter are sampling, quantizing and encoding. All the operations are usually performed in the same circuit called as analog-to digital convert Early electrical communications started to sample signals in order to multiplex samples from multiple telegraphy sources and to convey them over a single telegraph cable. The American inventor Moses G. Farmer conveyed telegraph time-division multiplexing (TDM) as early as 1853. Electrical engineer W. M. Miner, in 1903, used an electro-mechanical commutator for time-division multiplexing multiple telegraph signals; he also applied this technology to telephony.

Insert XXX to output the student's ID. public class Student { private double myGPA; private int myID; public getID) { return myI
Aleonysh [2.5K]

Answer:

Explanation:

The question above is missing many details and are actually various questions in one. I will answer each one seperately below...

A. The piece of code to get the ID in this code snippet that needs to replace XXX would be the following ... System.out.println("Student ID: " + s.getID());

B. A static main() can declare and create objects. Once these objects are created their instance methods can then be called.

C. Integer score1 = 72;

    int score2 = 85;

    Character grade = 'C';

     In the above code snippet, the information stored in score1, score2, and grade are the following... obj reference, 85, obj reference. This is becasue both Integer and Character are classes and the values being passed to their variables are referencing that object class, while score2 is a primitive type of int and is therefore simply a number.

D. The statement that is true is ... Contents of a Double instance can be modified after initialization. Objects can be modified by calling its setter methods after initializing it.

In a paragraph of no less than 125 words, explain what netiquette is and how it improves efficiency and productivity in the work
Pani-rosa [81]

Netiquette actually means "Internet etiquette." Just like etiquette is a code of polite behavior in society, netiquette is a code of good behavior on the Internet. This includes several aspects of the Internet, such as email, sending memos, or basic communication regarding office task.

Now we should note that communication is not just a pivotal part of any organization, it is an integral part of any organization, without communication, an organization will suffer greatly. Communication is said to be effective when the receiver understands the message conveyed just as the sender wanted to,  having said that Netiquette improves efficiency and productivity in the workplace because it creates an avenue for efficient communication which includes clear instructions, fast message delivery, and proper explanation, and this bridges the gap between managers and employees even when they are miles apart. A clear message about a task makes it easier to carry out the said task, thereby resulting in high productivity in the workplace.
