How will you define a text?

Answer:

Text refers to content rather than form; for example, if you were talking about the text of "Don Quixote," you would be referring to the words in the book, not the physical book itself. Information related to a text, and often printed alongside it—such as an author's name, the publisher, the date of publication, etc.—is known as paratext.

The idea of what constitutes a text has evolved over time. In recent years, the dynamics of technology—especially social media—have expanded the notion of the text to include symbols such as emoticons and emojis. A sociologist studying teenage communication, for example, might refer to texts that combine traditional language and graphic symbols.

The network layer is the layer is the layer 3 of the seven layer Open System Interconnect (OSI model) which functions as packet forwarder for the intermediate routers by implementing technologies used for switching that provides virtual circuits' logical path

The function of the network layer includes;

1) Routing and forwarding of packets to destination which enables connectionless communication

2) Enabling internetworking

3) Hierarchical host (IP) addressing

4) Sequencing of packets

5) Handling of errors

In a paragraph of no less than 125 words, explain what netiquette is and how it improves efficiency and productivity in the work

Ierofanga [76]

In very simple terms, netiquette is etiquette on the internet. It is a short form of network etiquette. It represents the importance of proper manners online. Common guidelines for good netiquette include being very courteous and avoiding instances of cyber-bullying. Although the specific protocols governing netiquette may differ depending on the forum being used, it is equally applicable to emails and surfing the internet, message boards, and chatting. In the workplace, netiquette implies that you have polite manners, and that you would want to build up relationships with people. By showing respect to your colleague through proper netiquette, it will show how productive you can be and as result, you will earn respect. Understanding netiquette in the workplace can save you from embarrassing moments. In sending job emails, for instance, always speak clearly and avoid using capitalized words, spelling errors, or slang.

Please help me with coding

NikAS [45]

There are many different ways you can learn how to code, You can use free and paid online courses, Youtube Videos, and Trial and Error. Programming does not come easy and you have to be patient with yourself. Its like learning to drive for the first time, its a little rough but you eventually will catch on and be able to understand what you are doing!

1.) There are many websites that will help teach you different languages like Java, JS, C#, Python, Ruby, Html5, etc.

Here are a few of my favorite websites that helped me.

Code Academy: https://www.codecademy.com/
Khan Academy: <span>https://www.khanacademy.org/
</span>W3Schools (Html Only, Not a Course just useful) http://www.w3schools.com/

I suggest going through those websites, or finding some other websites out there that will help you!

2.) Youtube Videos are perfect for learning specific things in programming! You can learn how to make a calculator, or a website, or anything you'd like! Just simply search for a how-to tutorial and watch the helpful videos! Remember, don't just copy the code.. try and understand it

3.) Trial and Error is one of the best ways you can teach yourself code. It was the best way for me to learn. Everyone learns from their mistakes and you should always try and come up with new things.

Be patient, and enjoy what you are doing! I also suggest working on one language at a time, don't try and learn two or more languages at the same time! Good luck :) Email me at any time if you need any help!
