Computers of the second generation use transistors rather than vacuum tubes.

Transistors and magnetic cores are the two different sorts of components that make up the second gen of computers. Compared to the first generation of vacuum tube-based computers, the transistors contributed to the development of a superior computer. IBM 1920, IBM 7094, CDC 1604, CDC 3600, IBM 1401, and others are examples of second-generation computers.

Answer:

D is the most likely answer

Answer:

D. you need to consider the position of power outlet(s) and peripheral devices as well as air flow around the system unit.

Explanation:

"When you click the file tab and then click print, word immediately sends the document to the printer." is TRUE statement.

A printer is a device that receives text and graphic output from a computer and prints the data on paper, typically on sheets of paper that are standard size, 8.5" by 11". The size, speed, sophistication, and price of printers varies. For more frequent printing or color printing with high resolution, more expensive printers are typically employed.

Impact and non-impact personal computer printers can be distinguished from one another. Early impact printers used a key to make an inked impression on the paper for each printed character, operating somewhat like an automatic typewriter. A common low-cost choice was the dot matrix printer, an impact printer that prints one line at a time on the paper.

To navigate to the /home/jim directory, the user could type the following command: "cd ../../".

To navigate to the "/home/jim" directory, the user could use the command "cd ../..". The "cd" command is used to change the current working directory, and ".." refers to the parent directory. By using "../.." the user moves up two directories in the hierarchy, which takes them from "/home/jim/sales/pending" to "/home/jim".

In a computer file system, a directory is a special type of file that contains a list of other files and/or directories. Directories can be used to organize files into a hierarchical structure, making it easier to find and manage them. The structure of directories and files within a file system is referred to as the directory tree. The top-most directory in the directory tree is called the root directory, and it is denoted by a forward slash "/" in Unix-like operating systems and a backslash "" in Windows operating systems.

Answer:

a. a minor on Friday with the discount code

Explanation:

Let's try and decipher the given code segment

Let's first look at the if part

if (age <= 18 && day != "Saturday" && day != "Sunday") {

              price = price / 2;

==> if a minor and a weekend then price is half = $5

Now look at the else part

else if (day == "Friday" && discountCode == "FREEFRIDAY"){

             price = 0;

}

This means if the visitor is NOT a minor and it is NOT a weekend if it is a friday, with a coupon then admission is free

Let's look at the answer choices and see what the logic flow is:

a. minor on Friday with the discount code
if (age <= 18 && day != "Saturday" && day != "Sunday")
All three parts of this condition are true so the statement price = price/2 is executed and price = 5. However, everyone with this coupon should get in free. So this part is incorrectly coded

b. an adult on Friday with the discount code
if part is False, else if part is true and price = 0 which is consistent

c. an adult on the weekend
if part is false, else if part is also false so price printed out is 10 which is consistent

d. a minor on the weekend
the if part is false and so is the else if part , so price is unchanged at 10. Consistent

e. an adult on a weekday
Both the if and else if parts are false, so price is unchanged at 10. COnsistent

How to get the output?

After that, using a for loop, I allowed user to enter these keys in that array. This loop goes from 0 to numberofquestions-1. So, every element of key[] array is assigned a value. Inside the do-while loop, I used another do-while loop to get student answers. This could also be done with while or for loop in the same way because here the number of iterations are same: numberofquestion times the loop takes input. After that, it compares that value with key [ ] element like ans 3 with key[2] and so on. I have not stored that inputs as mentioned in questions, directly I compared them and if the key and student answer is same, correct answers count is incremented by 1. At last, it prints the % by dividing number of correct with total number of questions. If user selects y to re-run the program, it asks to enter answers by another student as the key is to be remained same.

Grounding the cylinder to dissipate the static electricity connect through a safe conductive path.

Grounding is the process of connecting the cylinder to a conductive material, such as a metal rod, in order to provide a path for the static electricity to flow away from the cylinder and into the ground. The metal rod is connected to the cylinder through a wire, which is then connected to an earth ground. The static electricity is then conducted away from the cylinder, preventing a spark that could cause a dangerous ignition of the flammable gas. Grounding is a common safety measure taken when dealing with flammable gases, as it reduces the risk of an ignition due to a build-up of static electricity.
