This is one which was used in computers before the Phenomenal invention of Transisitors.

Answer 2

A glass tube containing electrodes used as a switch to produce on or off signals for the computer is a Vacuum Tube.

What is a vacuum tube?

A vacuum tube is a tube that controls the transfer of electrons inside a tub. It is a valve. It is also called an electronic device used in television, amplifiers, radios, etc.

A vacuum tube contains a cathode and anode. The cathode is heated, and it emits or releases electrons. This emission is called thermionic emission. It controls the transfer of electrons, in a high-charge device. This is applied to the device where the electric potential difference is very high.

Vacuum tubes are used in old times, they are still used in some industries.

Thus, a vacuum tube is a glass tube with electrodes that serves as a switch to generate on or off signals for the computer.

How to Print output in JavaScript

Answers

If you want to print on a page you can use

document.write();

If you want to write in console then there are multiple options

console.log() - to log information

console.error();- to log errors

console.warn(); - to log warning message

If you want to popup some information the you can use -

alert(message);

there are also various options present in alert.

or

print() essentially just calls up the native print dialog for a given window.

But as you're are thinking, it will work on any window or (i)frame.

thus if you write content to a frame, you can then call this to print it.

window.frameName.print();

note the only drawback (and its a big one), is that this calls up the print dialog... not the print preview window... thus the user doesn't really get a chance to see what they are printing and/or scale it to fit their printer/paper.

I personally wish that all browsers would implement the following to handle the above issue.

window.printPreview();

Write a MATLAB function named average_of_scores_with_drops The function will have two inputs and two return values. The first input will be a list of scores. The second input will be a postive integer representing the number of scores to drop. It will not be larger than the length of the list. Your function should determine the average of the scores after dropping the specified number of lowest scores. The first return value must be a real number equal to the average score. The second return value must be the number of items that were averaged. Notes: Example Test Case: SCORES

Answers

Answer:

-%Define the function.

function [avg, ele_left] = average_of_scores_with_drops(input_list, drop_element)

%Sort the list.

input_list = sort(input_list);

%Compute the length of the list.

len_list = length(input_list);

%Declare and initialize the variable.

sum = 0;

%Increase the element to be drop by 1.

i = drop_element + 1;

%begin the for loop.

What is programming language?

Programming language is defined as a computer language used to converse with computers by programmers (developers). Orthogonality or simplicity, available control structures, data types, and data structures, syntactic design, support for abstraction, expressiveness, type equivalence, strong versus weak type checking, exception handling, and limited aliasing are among the characteristics of a programming language.

Clarity, simplicity, and unity offer a way to express algorithms as well as a framework for thinking about them. Every possible feature combination has value thanks to orthogonality. Surprisingly, it may frequently be reduced to three basic programming constructs known as loops, selects, and sequences.

Answers

Answer:

d. all of the above are true

Explanation:

Connectionless Packet Switching is a term that is used in computer networking operations to describe the breaking of information exchange path into a various packet of small sizes acquired and refined over network switches and routers, which is then transferred from one subsequent node to the other. It is sometimes referred to as Datagram Networks

However, during this operation, Connectionless Packet Switching must satisfy the following amongst others:

1.  each datagram must comprise both source and destination addresses

2.   without a connection, datagrams may not come in sequential order at the destination

3.  establishment of a connection between communicating points is not needed prior to exchanging datagrams, thus reducing overhead communications

Therefore, considering the available options, the correct answer is option D

Explain demand paging with a proper example

Answers

Demand paging :

In computer operating systems, demand paging (as opposed to anticipatory paging) is a method of virtual memory management. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it and that page is not already in memory (i.e., if a page fault occurs). It follows that a process begins execution with none of its pages in physical memory, and many page faults will occur until most of a process's working set of pages are located in physical memory. This is an example of a lazy loading technique.

Fortunately, she was able to eliminate it before it resulted in a denial-of-service attack, which would have prevented legitimate users of the networked database from gaining access to the records needed. It turns out that the network software did not have adequate security protections in place. The fact that this virus was successfully inserted into the network software points to a vulnerability of the network software.

In Cybersecurity, vulnerability can be defined as any weakness, flaw or defect found in a software application or network and are exploitable by an attacker or hacker to gain an unauthorized access or privileges to sensitive data in a computer system.

This ultimately implies that, vulnerability in a network avail attackers or any threat agent the opportunity to leverage on the flaws, errors, weaknesses or defects found in order to compromise the security of the network.

Some of the ways to prevent vulnerability in a network are;

1. Ensure you use a very strong password with complexity through the use of alphanumerics.

2. You should use a two-way authentication service.

3. You should use encrypting software applications or services.

This question is incomplete, the complete question is;

The binary string 00100100 is a member of which of the following problems? Remember, a "problem" is a language whose strings represent the cases of a problem that have the answer "yes." In this question, you should assume that all languages are sets of binary strings interpreted as base-2 integers. The exception is the problem of finding palindromes, which are strings that are identical when reversed, like 00100100, regardless of their numerical value.

a) Is the given string a palindromes ?

b) Is the given string a perfect cube?

c) Is the given string greater than 50?

d) Is the given string even?

e) is the given string a perfect square?

Answer:

a) the given binary string is a palindromes

b) the given string is NOT a perfect cube

c) the given string is NOT greater than 50?

d) the given string is an even

e) the given string a perfect square

Explanation:

Given that;

binary string : 00100100

a)

Is the given string a palindromes ?

the given binary string = 00100100

now when you reverse the string, its still going to be : 00100100

so the given binary string is a palindromes

b)

Is the given string a perfect cube

the given string : 00100100 = 36

now 2^3 = 8,

3^3 = 27,

4^3 = 64

so 36 is not a perfect cubic

hence the given string is NOT a perfect cube

c)

Is the given string greater than 50?

the given string : 00100100 = 36

and 36 < 50

so the given string is NOT greater than 50?

d)

Is the given string even?

the given string  : 00100100 = 36

and 36 can be divided exactly by 2

so the given string is an even

e)

is the given string a perfect square?

the given string  : 00100100 = 36

now 6^2 = 36  i.e 6 multiply by 6 = 36

therefore the given string a perfect square

How do I fix the error?

Answers

Answer:

num = int(input("Enter a number: "))

print(num * 8)

Explanation:

I highlighted the parts that are added

Since you are getting an input from the user, you need to set the result to a variable. In this case, it is num.

Since it is a number, you need to specify the its type. In this case, it may be int.

Also, the quotation marks must be written as seen.

The corrected program which ensures that the program runs correctly is written thus :

num = int(input("Enter a number: ")

#user supplied input should be assigned to the varibale num

print(num * 8)

#multiplies num by 8 and displays the output.

The num variable in the second line isn't attached to any value, therefore, it will throw an error.

The user input value should be attached to the variable, 'num'

The second line of code multiplies num by 8 and displays the product.

Therefore, if the the user input is 3 ; the final result displayed will be : (3 × 8) = 24.
