So you have to check the availability of domain name before you register it, for this www.whois.net website will help. If the domain name entered is available then we can register it by paying the Annual registration fees through online.<\/p>\n<p><span style=\"color: #0000ff;\">FTP (File Transfer Protocol) client software<\/span><\/p>\n<p>When a client requests a website by entering website address. Then FTP client software helps to establish a connection between client computer and remote server computer.

Instead of http:\/\/, it uses ftp:\/\/.<\/p>\n<p>By using FTP client s\/w we can transfer(upload) the files from our computer to the web server by usrng the \u2018drag and drop\u2019 method.

The website is designed dynamically(flexibly) that suit the screen size of different device introduced by Ethan Marcotte. Before this, companies have to design different websites for different screen sized devices. By responsive web design, companies have to design only one website that suitably displayed according to the screen size of the devices.<\/p>\n<p>It is implemented by using flexible grid layout, images and media queries<\/p>\n<ul>\n<li>Flexible grid layouts : It helps to set the size of the web page to fit the screen size of the device.<\/li>\n<li>Flexible image and video : It helps to set the image or video dimension to fit the screen size of the device.<\/li>\n<li>Media queries : There is an option(settings) to select the size of the web page to match our device, this can be done by using media queries inside the CSS file.<\/li>\n<\/ul>\n<p>A well known Malayalam daily Malayala Manorama launched their responsive website.<\/p>\n<h4><a href=\"https:\/\/cbselibrary.com\/plus-two-computer-science-notes\/\">Plus Two Computer Science Notes<\/a><\/h4>\n","protected":false},"excerpt":{"rendered":"<p>Kerala Plus Two Computer Science Notes Chapter 7 Web Hosting Web hosting Buying or renting storage space to store website in a web server and provide service(made available 24&#215;7) to all the computers connected to the Internet.
