Internet web and technology
Internet:-
a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols.
www:-
The World Wide Web (WWW), commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators (URLs, such as https://www.example.com/), which may be interlinked by hypertext, and are accessible over the Internet.[
BROWSER:-
a computer program with a graphical user interface for displaying HTML files, used to navigate the World Wide Web.
SEARCH ENGINE:-
a program that searches for and identifies items in a database that correspond to keywords or characters specified by the user, used especially for finding particular sites on the World Wide Web.
CLIENT SERVER MODEAL:-

Client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients.[1] Often clients and servers communicate over a computer network on separate hardware, but both client and server may reside in the same system. A server host runs one or more server programs, which share their resources with clients. A client does not share any of its resources, but it requests content or service from a server. Clients therefore initiate communication sessions with servers, which await incoming requests. Examples of computer applications that use the client–server model are Email, network printing, and the World Wide Web.
URL:-
A Uniform Resource Locator (URL), colloquially termed a web address,[1] is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI),[2][3] although many people use the two terms interchangeably.[4][a] URLs occur most commonly to reference web pages (http), but are also used for file transfer (ftp), email (mailto), database access (JDBC), and many other applications.
WEB PAGES:-
A web page (also written as webpage) is a document that is suitable to act as a web resource on the World Wide Web. In order to graphically display a web page, a web browser is needed. This is a type of software that can retrieve web pages from the Internet. When accessed by a web browser it may be displayed as a web page on a monitor or mobile device. Typical web pages are hypertext documents which contain hyperlinks, often referred to as [1]links, for browsing to other web pages.
WEBSITE:-
A website[1] or web site[2] is a collection of related network web resources, such as web pages, multimedia content, which are typically identified with a common domain name, and published on at least one web server. Notable examples are wikipedia.org, google.com, and amazon.com.
Websites can be accessed via a public Internet Protocol (IP) network, such as the Internet, or a private local area network (LAN), by a uniform resource locator (URL) that identifies the site.
TYPE OF WEBSITE:-
A website can be of different types depending upon how often the content needs to be updated or how the page is viewed at different browser width. These can be differentiated as:
- Static Website
- Dynamic Website
- Responsive Website
STATIC WEBSITE:-
Static Websites, also known as fixed websites are the most simplistic websites which contains web pages which with fixed content. This means their content do not change depending on the user.
Static websites are built using simple HTML code and display same information to every user. The codes are fixed for each page so the information provided on the page does not change unless it is manually updated. Generally, static websites are cheaper and easier to create
Resizing the browser or viewing it on different devices won’t affect the way website looks. These websites have a set width and require horizontal scrolling.
DYNAMIC WEBSITE:-
Dynamic Websites, also known as fluid websites contain dynamic web pages that are generated in real time. This means that the web pages will display different content each time the site is visited. These pages include web scripting code, such as PHP, ASP or JSP.
Dynamic pages access information from a database. Hence, webmaster may only need to update the database record in order to alter the content of dynamic pages. Unlike Static websites, dynamic websites have more personal and interactive user experience.
These websites takes slightly slower time to load in comparison to Static as they are little more complex to develop. Dynamic websites looks same in terms of proportions no matter what the screen size.
RESPONSIVE WEBSITE:-
There is another type for websites which is widely used these days. The websites which are built with percentages instead of exact measurements. These websites are called as Responsive Websites which are optimised for smartphones and tablets. Responsive websites used actually look different on each device. The elements stretches or shrinks according to the screen size. These websites are built using a mobile-first approach.
A large proportion of the users use mobile phones to view the site. Therefore, most of the companies nowadays opt for responsive web design services, whether they work on small scale or large as it offers best experience to such users.
WEB SERVICE:-
The term Web service (WS) is either:
- (generic) a service offered by an electronic device to another electronic device, communicating with each other via the World Wide Web, or
- (specific) a Web service is a server running on a computer device, listening for requests at a particular port over a network, serving web documents (HTML, JSON, XML, Images), and creating web applications services, which serve in solving specific domain problems over the web (www, internet, HTTP)
In a Web service a Web technology such as HTTP — originally designed for human-to-machine communication — is used for transferring machine-readable file formats such as XML and JSON.
