What are the four generic architectural components of a public communications network? define each term?

Answers

Answer 1
Like every telecommunication network, the public communication network consists of  terminal nodes connected with each other through transmission links. Packet switching enables passing the signal through the correct links and nodes to reach the correct destination terminal. 
The four generic architectural components are: Subscribers ( the devices at the end-users: telephones and modems), subscriber line (the transmission link between the subscriber and the network), exchanges (the switching centers in the network) and trunks: the branches between exchanges.

The ____ loop is particularly useful when processing arrays.

Answers

The FOR EACH loop is particularly useful when processing arrays. The newer for statement is called the enhanced for or for each because it is called this in other programming languages. It is used in preference to the standard for loop if applicable because it is much readable. The series of value of the for each loop is used to access each successive value in a collection values. It is commonly used to iterate over an array or a collection class, for example is the array list. It can also iterate over anything that implements the iterable interface which is the define iterator method. Many of the collections classes implement iterable which makes the for each loop very useful.

Final answer:

The for loop is particularly useful when processing arrays. When you need to iterate over array elements, the for loop allows you to execute a block of code a certain number of times, which corresponds to the length of the array.

Explanation:

Arrays are collections of data items that are accessible via numeric indices. To process each element in an array, you often need to access them sequentially, starting with the first element and ending with the last. The for loop is ideal for this situation because you can define a loop control variable that starts at 0, then incrementally increase it in each iteration until it matches the length of the array (usually one less than the array length because array indices typically start at 0). This way, you can work through the array systematically. The for loop provides a clear structure for iterating over arrays and is compact in syntax, making it a preferred choice among programmers when dealing with collection-based data structures like arrays.

It's safe to download files from the internet if you perform regular windows security undated; that is all you need to protect your computer from viruses

Answers

No, Microsft recommends you purchase and install a Virus Protection  Program despite having its own free version Microsoft Security Essentials. If you notice on any new computer, usually McAfee/Trend or any other Virus Protection program is preinstalled and active for a few months. There are pretty good free versions out there, Total AV and PC Protect are very good and have high rankings.

Final answer:

Regular Windows security updates are crucial but not the sole measure to protect against viruses; antivirus software and safe browsing habits are also needed. Upgrading Windows may be needed for compatibility with newer files.

Explanation:

The question concerns whether performing regular Windows security updates is sufficient to protect a computer from viruses when downloading files from the internet. While keeping your Windows operating system up to date is crucial for security, it is not the only measure you should take to protect your computer. Antivirus software, safe browsing habits, and a firewall are also essential components of a comprehensive security approach.

Furthermore, the concept of planned obsolescence addressed in the provided information speaks to a different issue related to software compatibility rather than virus protection. Upgrading your Windows operating system may be necessary to maintain compatibility with newer files, but it is a separate concern from the question of safety in downloading files.

You're working at a large industrial plant and notice a tag similar to the one shown in the figure above. Which of the following actions should you take?

A. Operate this switch only if more than 24 hours have elapsed since the tag was signed.
B. Operate this switch only after making certain no one is working on the affected circuit.
C. Operate this switch only after normal working hours.
D. Operate this switch only after getting permission from the person who signed the tag.

Answers

Hey there!

Even if there isn't anyone working on the circuit at the moment, it still may be exposed and activating it could cause a variety of problems. This means that whoever is present or whatever time you would activate the circuit is irrelevant as the switch should only be thrown after permission is given. 

Logically, you would need permission from whoever ordered against throwing the switch in the first place, which should be the person who signed it. I believe that your answer will be "Operate this switch only after getting permission from the person who signed the tag", which is D.
