Creativity Within Structure

Lets take a quick look into the network traffic that is generated when an activity occurs such as a file download via an HTTP request. We will also look further into the TCP protocol handshake, sequence numbers, and their values. We will examine their significance resulting from the HTTP request. What role does TCP play during HTTP requests? Is TCP a connection-oriented protocol? Explain in details. A TCP header has Flags field. Describe the meaning of flags "SYN", "SYN ACK" and "FIN". Transmission Control Protocol is, as its name states, controls the transmission of an application between end points. HTTP is the application layer in this case, TCP provides for the reliable delivery of HTTP requests. It passes over to the network layer. A user initiates an HTTP request by opening a browser and requesting a web page via a URL. The server will then deliver the request, and any objects such as images, movies, PDF files etc that the web page may have em

There are 4 pseudo-class expressions that are part of the :nth-child pseudo-class. Structural pseudo-class selectors target HTML elements based on the DOM tree. Basically, elements that cannot easily be targeted by simple selectors or combinations of selectors. What makes pseudo-classes so handy is the ability style elements dynamically based on its position in the DOM. :nth-of-type(N) :nth-last-child(N) :nth-child(N) :nth-last-of-type(N) :nth-of-type(N) selector My favorite of the 4 is the :nth-of-type(N) selector. The nth-of-type selector allows you to select child elements of a parent based on the particular type of the element, for example every 5th "li" element in a list. You can select even or odd elements, or the nth (order number) child in the group of elements. The class accepts the argument "n" which can can be a keyword, a number, or strings "odd", "even", or an expression "-n+3". Let's look at a simple but ef
