Answer:(C) Anyone with access to the personal computers could log on to the mainframe.
Explanation:
It is no doubt that log on procedures are cumbersome so what most users do is that they store log on sequences in their computer so that they could use the main frame facilities whenever they access it the second time.
Here we have to identify the associated risk with this approach.
This process could lead to access of the computer system to users and thereby making all the data available in the system vulnerable. So option C is correct.
option (A) is incorrect as the back up option who also be affected when the system is accessible to anyone.
option (B) is incorrect because it has nothing to do anything with training of the personnel.
option (D) is incorrect because it one has nothing to do with the physical system what vulnerable reside is inside the system.
Answer:
see explaination
Explanation:
//selective dev elements by id name
var gradeA = document.querySelector("#GradeA");
var passing = document.querySelector("#Passing");
var learning = document.querySelector("#Learning");
//function showGrades
function showGrades() {
var arr = [];
//converting string to int and inserting into array
arr[0] = parseInt(gradeA.textContent);
arr[1] = parseInt(passing.textContent);
arr[2] = parseInt(learning.textContent);
//creating json blob
var blob = new Blob(new Array(arr), {type:"text/json"});
return blob;
}
The correct answer is C) ease of use.
The fact that a web app is written to be run within any of the standard browser and on any platform on which that browser operates is called "ease of use."
The ease of use concept indicates that the product is "amicable" or "friendly" to use by most people because it is not required andy technical knowledge to operate the product. In this case, the app is written to be run within any of the standard browser and on any platform on which that browser operates, so it is "friendly" to operate bu most systems. App's companies and software companies created this "ease of use" concept for many of their products so they can sell most of them because people know they are easy to use and functional.

<u>Explanation:</u>
Steganography is a technique used in securing or hiding sensitive information by encrypting the information in a non-hidden file like a JPEG format. A major <u>advantage</u> of this method is that it reduces the risk of attack or break-in since the data is enclosed in a non-secure file; thereby reducing threats of any hack. One main<u> disadvantage</u> of this method is that the hidden message may become difficult to recover if the source file (non-secure file) used, is edited or deleted.
In symmetric or asymmetric encryption they both employ cryptographic encryption method. While symmetric encryption uses one key to encrypt and decrypt data, asymmetric encryption uses two keys (one for encryption, the other for decryption) of the data. <u>A major </u><u>advantage</u><u> of using these methods is that they provide more security. Although while symmetric encryption is faster, asymmetric encryption is slower (eg using separate keys to gain access), </u><u>a disadvantage.</u>
