Answer:
The answer is: Only A is correct.
Explanation:
Variables in a program can assume different values at different times, and the program can then produce different results, depending on circumstances, so A is correct.
In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use". This is a syntactic definition, and a reserved word may have no meaning. So, B is incorrect.
Hence, the answer is: Only A is correct.
Answer:
1. A high level algorithm for cooking a cheeseburger could be:
- Heat fry pan
- Cook one side of the hamburger
- Wait
- Turn hamburger upside down
- Put cheese over hamburger
- Wait
- Cut hamburger bread in half
- Put cooked hamburger inside bread
- End (eat)
2. A detailed algorithm for cooking a cheeseburger could be:
- Place fry pan over the stove heater
- Turn on heater (max temp)
- IF fry pan not hot: wait, else continue
- Place raw hamburger on fry pan
- IF hamburger not half cooked: Wait X time then go to line 5, else continue
- Turn hamburger upside down
- Put N slices of cheese over hamburger
- IF hamburger not fully cooked: Wait X time then go to line 8, else continue
- Turn off heater
- Cut hamburger bread in half horizontally
- Put cooked hamburger on one of the bread halves.
- Put second bread half on top of hamburger
- End (eat)
Explanation:
An algorithm is simply a list of steps to perform a defined action.
On 1, we described the most relevant steps to cook a simple cheeseburger.
Then on point 2, the same steps were taken and expanded with more detailed steps and conditions required to continue executing the following steps.
In computational terms, we used pseudo-code for the algorithm, since this is a list of actions not specific to any programming language.
Also we can say this is a structured programming example due to the sequential nature of the cooking process.
Because there is a very likely chance you can get electrocuted which could lead to medical treatment or even death. Also if working near trees or polls or anything that is touching a power line may lead to you being electrocuted.

Answer:
The correct answer is: 255.255.255.192.
Explanation:
A subnet mask complements an Internet Protocol (IP). Thanks to subnet masks IP addresses can be identified because they seem to be all the same but the subnet mask avoids confusion. If four subnets are to be created for the IP 192.168.90.0 3 bits of that IP must be used to create the subnet resulting in 255.255.255.192. Then:
- <em>Number of subnets</em>:
- <em>Number of hosts per subnet</em> =
