Knowing what you know now about frequency analysis, would you feel comfortable sending your password over the Internet using a substitution cipher? Why or why not?
Substitution ciphers in the world of encryption can be cracked very easily. By looking for patterns like one letter words, double letter patterns, and knowing rules such as all words must contain at least an a, e, i, o, u or y, you are probably able to decipher this with so much ease. While this information and the frequency of letters used in the encrypted message might be helpful, it might not be a perfect process.
Answer:
No, because substitution ciphers can be broken very easily by frequency analysis.
Explanation:
No, because substitution ciphers can be broken very easily.
They are the oldest form of cipher, look at, for example, Caesar's Cipher.
In a substitution cipher each letter is assigned a ciphered letter. For example, a is assigned d, b assigned e and as follows. By frequency analysis, it is very easily to be broken. For example, in the english language, let's say a is the most frequent character. So in the ciphered text, d is going to be the most frequent character.

7. Do you believe the advantages of using Twitter as a news source (i.e. speed) outweigh the disadvantages (i.e. unreliability)?
Final answer:
The advantages and disadvantages of using Tw-itter as a news source need to be carefully considered, as the speed of information may outweigh the unreliability of the platform.
Explanation:
The question asks whether the advantages of using Twit-ter as a news source outweigh the disadvantages.
While Twit-ter can provide news quickly, it is important to consider the reliability of the information. Social media platforms like Twi-tter have been found to spread false information faster than the truth and can also influence people's opinions.
Therefore, it is essential to critically evaluate the credibility of the news shared on Twi-tter.

When using a wireless connection, ________ translates data so that it is protected?
Encryption ensures the confidentiality of information transmitted over an insecure wireless network. Wireless networks are more susceptible to security attacks and are insecure by nature. However, data encryption protects the vulnerable wireless link between access points and client devices by encrypting all data in the transmission.

The search must only use one quotation mark or less.
What is quotation?Quotation is defined as a method of referencing typographic or phonetic shapes by displaying examples, i.e., writing or speech that has those shapes. Quotes in computer programming might be text or other information. The text that is being printed to the screen, for instance, is frequently encircled by quotations in the print statement below.
There are a number of techniques to perform a more precise search using search engines; for example, employing specific characters makes it simpler to conduct advanced searches in a particular theme. You must include a phrase in quote marks if you want to search for it, for instance as it was entered. Ambiguity is removed by using a minus sign after the searched term since it tells to consider other meanings instead of that one.
Thus, the search must only use one quotation mark or less.

The answers to the problems are given in the bold font statements below
Explanation:
The instructions for a computer program are sometimes referred to as program code. Computer programmers focus on programming computer programs, but they also plan, test and document computer programs. In contrast, software programmers apply formalized techniques to reduce the cost and complexity of software while increasing reliability. Before a program can be written, a programmer needs a clear problem statement, which includes a list of assumptions, a description of known information, and a specification for what constitutes a solution. Programming projects can be approached using a(n) predictive methodology, which requires extensive planning and documentation up front. An alternative approach is to use the agile methodology in which programs are developed in iterations called sprints. With a clear plan, a programmer can begin composing using a text editor, program editor, or visual development environment. Programs are composed of a series of statements that include a(n) command words such as input or print and parameters. Those parameters may include variables that represent values that can change, or constants that that represents unchanging values. All computer programs should include internal documentation in the form of remarks which are explanatory comments inserted into a computer program following language-specific symbols, such as # or keywords such as REM. A program is not complete until it has been tested to ensure that it contains no syntax errors, logic errors, or run time errors. Programmers can use formal methods based on rigorous logical and mathematical methods to reduce the number of defects in a software product. Additional techniques for producing high-quality, secure programs include threat modeling and defensive programming.
In shell scripts, comment lines begin with a(n) ____.
In shell scripts, comment lines begin with a # character.
In shell scripts, comment lines begin with a # character. This means that any text following a # on a line will not be executed by the script; it is considered a comment. Comments are useful for adding explanations or notes within the script, which can clarify what each part of the script does.
For example:
# This is a comment lineIt is important to note that the #! (shebang) is a special type of comment used at the very beginning of a script to indicate which interpreter to use, such as:
#!/bin/bashEverything after the # character is ignored by the interpreter, making comments a powerful tool for documenting and organising your shell scripts.

To modify a video after inserting it into your presentation, you can change playback options, adjust the video length, and apply various formats and styles using the Video Tools tab. You must also consider the overall length of your presentation and file size when including videos.
After you insert a video, you can modify it by changing playback options, changing the length of time the video plays, and applying formats and styles to the video. Once the video is inserted, you may need to move and resize it to ensure it is legible for the audience.
When a video object is selected in your presentation software, such as PowerPoint, a new contextual Video Tools tab appears, providing options for Formatting and Playback. The Playback tab, in particular, has a variety of options to customize how the video will impact the audience.
It is crucial to consider the overall length of your presentation when including videos, as they can be quite lengthy and presentations should remain focused and on schedule. Additionally, the large file sizes of videos present challenges regarding storage and portability.
