What is CSS? Features of CSS.
CSS is used to control presentation, formatting, and layout. Whereas HTML was the basic structure of your website, CSS is what gives your entire website its style. Those slick colors, interesting fonts, and background images? All thanks to CSS. It affects the entire mood and tone of a web page, making it an
incredibly powerful tool - and an important skill for web developers to learn. It's also what allows websites to adapt to different screen sizes and device types.
Give the characteristic сommunicating over the Network?
1. A computer network or data network is a telecommunications network which allows nodes to share resources. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.
2. Network computer devices that originate, route and terminate the data are called network nodes.[1] Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other.
3. Computer networks differ in the transmission medium used to carry their signals, communications protocols to organize network traffic, the network's size, topology and organizational intent.
4. Computer networks support an enormous number of applications and services such as access to the World Wide Web, digital video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messagingapplications as well as many others. In most cases, application-specific communications protocols are layered (i.e. carried as payload) over other more general communications protocols.
How create an HTML Webpage?
HyperText Markup Language (HTML) is the standard markup language for creating web pages and web applications. With Cascading Style Sheets (CSS), and JavaScript, it forms a triad of cornerstone technologies for the World Wide Web.[1] Web browsersreceive HTML documents from a webserver or from local storage and render them into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document.
5. HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects, such as interactive formsmay be embedded into the rendered page. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. HTML elements are delineated by tags, written using angle brackets. Tags such as <img /> and <input /> introduce content into the page directly. Others such as <p>...</p> surround and provide information about document text and may include other tags as sub-elements. Browsers do not display the HTML tags, but use them to interpret the content of the page.

What is the purpose the TCP/IP protocols ?
The purpose of TCP/IP is to make it easier for computers to communicate with one another to send information over the Internet. It is a set of protocols that computers use so that they essentially speak the same language when passing information. TCP/IP tells the computer how to put together data packets before they are sent across the internet, and it breaks these packets down into small bits. It does the opposite on the other end, reassembling them so that they make sense to the receiving computer. The TCP/IP protocols determine how the information is sent, tell the computer how to address them and move them across the Internet
What are the differences between IP addresses and domain names?
IP addresses work for communication between computers, people find it difficult to remember long strings of numbers. Therefore, many Internet servers also have an easy-to-remember name, such as nike.com. The official term for this name is fully qualified domain name (FQDN), but most people just refer to it as a domain name.
By convention, you should type domain names using all lowercase letters.
A domain name is a key component of Web addresses, e-mail addresses, and addresses on the Web called URLs. It is the Web server name in a Web address and the e-mail server name in an e-mail address. For example, in the Web address www.msu.edu/infotech, the domain name is msu.edu.
