What is the purpose of using modulo 2 arithmetic rather than binary arithmetic in computing an fcs?
The purpose of using modulo 2 arithmetic in computing an FCS is to detect transmission errors through simple and efficient calculations. It provides a checksum that can be used to verify data integrity, detecting common errors like single-bit and burst errors. This method does not require handling carry operations, simplifying implementation.
Explanation:The purpose of using modulo 2 arithmetic in computing a Frame Check Sequence (FCS) is to provide error detection capability when data packets are transmitted over a network. Modulo 2 arithmetic is a simple, efficient method of calculating a type of checksum that can be used to verify the integrity of the transmitted data. By performing bitwise exclusive OR (XOR) operations on the data bits, modulo 2 arithmetic generates a value that can be appended to the data. When the data is received, the same operations are performed, including the FCS. If the result is zero, it is assumed that the data has not been corrupted during transmission.Modulo 2 arithmetic is used because it resembles binary addition without carry. It simplifies the hardware or software implementation since handling carry operations is not required. Also, modulo 2 arithmetic can detect common errors such as single-bit errors and burst errors that can occur in communication channels, providing a simple yet robust way to ensure data integrity. This method is commonly used in network protocols, for example, in the Cyclic Redundancy Check (CRC).
You are logged in as a user with limited system privileges, you are the linux system administrator and you have the password to the root user account. when you need to switch to root user to perform administrative tasks, what command would you enter at the command prompt?
What does limited access to a document mean?
It makes a document inaccessible without a password.
It enables a person to make changes and automatically save them.
It does not reflect any changes made in the document.
It enables a person to read the document but not edit it.
It blocks a person from accessing a document.
Answer:
C). It enables a person to read the document but not edit it.
Explanation:
Limited access to a document is primarily associated with the creator of document restricting the usage and changes that can be made to a specific document. It assists the users to protect the authenticity of their document and prevent it from any unnecessary editing to the document. Therefore, the limited access to a document would imply 'enabling a person to only read the document but not edit or make changes to it' without the creator's permission. It is thus aimed to limit the access to a specific content. Therefore, option C is the correct answer.
True or false while the internet and social media are vital for spreading campaign messages, television advertisements are considered ineffective

Advantages of Visual Aids in a Presentation:
A picture is worth a thousand words - presentation softwares let you display images and videos that help prove the speaker's theses. By using graphics to show trends or using photographs to showcase a product, the speaker helps the audience better visualize (and therefore understand) what he or she tells you.Appeals to many senses - While oral speech mainly stimulates hearing, the use of multimedia tools stimulates other senses, especially vision. To see is to feel. And for some auditoriums that makes all the difference: Have you ever wondered why tradeshow vendors insist on permanently repeating demonstrations without forgetting the videos that explain the benefits of their products?Greener and more versatile support - Multimedia presentations save paper: a single presentation can be seen by all members of the auditorium without photocopying. On the other hand, they allow greater creativity and originality in the presentation of contents when compared to paper.Easy content creation - Multimedia tools allow you to quickly and simply dress up and embellish the speaker's ideas and make them visually appealing. In fact, no Visual Design course is required to make captivating slides.Using Word, Maureen is writing an outline of a presentation she plans to give to her company.
