Go for Bangla Version

 

Web Design:

Web design is the process of creating the layout of a web page or an entire website. This process focuses on aesthetic factors like layout, user interface and other visual imagery in order to make the website more visually appealing and easy to use. Web design makes use of various programs and tools in order to achieve the intended look, such as Dreamweaver, Photoshop and many others.

 

Internet: 

The Internet is a network of networks. It is a globally connected network system that uses TCP/IP to transmit data via various types of media. It was conceived by the Advanced Research Projects Agency (ARPA) of the U.S. government in 1969 and was first known as the ARPANet (Arpanet-Advanced Research Projects Administration Network).The original aim was to create a network that would allow users of a research computer at one university to “talk to” research computers at other universities.

 

Web:

The Web is the common name for the WWW (World Wide Web), a subset of the Internet. The Web is just one of the ways that information is shared over the Internet. Many people assume that the Web is the same as the Internet, and use these terms interchangeably. Web consisting of three technologies-

  • HTML (Hyper Text Markup Language)
  • HTTP (Hyper Text Transfer Protocol)
  • Web browser

Tim Berners-Lee implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the internet in mid-November of 1989 and thus is considered as the father of WWW.

 

Web page: 

A web page is a document commonly written in HTML(Hypertext Markup Language) that is accessible through the Internet or other networks using an Internet browser. A web page is accessed by entering a URL address and may contain text, graphics, and hyperlinks to other web pages and files. The page you are reading now is an example of a web page.

 

Website: 

Website is a collection of related web pages under a specific domain that may contain text, images, audio and video. The first page of a website is called home page. Each website has specific internet address (URL) that you need to enter in your browser to access a website. Though the two terms are often used interchangeably. For example, EduPointBD.com is a Web site, but there are many Web pages that make up the site.  

 

Web Portal: 

A web portal is a specially designed website that brings information from diverse sources, like emails, online forums and search engines, together in a uniform way.

For example- www.bangladesh.gov.bd is a web portal; where all the important links of Bangladesh reside.

 

Server/ Server Computer: 

A server is a computer that provides data to other computers. It may serve data to systems on a local area network (LAN) or a wide area network (WAN) over the Internet.

Many types of servers exist, including web servers, mail servers, and file servers. Each type runs software specific to the purpose of the server. For example, a Web server may run Apache HTTP Server or Microsoft IIS, which both provide access to websites over the Internet. A mail server may run a program like Exim or iMail, which provides SMTP(Simple Mail Transfer Protocol) services for sending and receiving email. A file server might use Samba or the operating system’s built-in file sharing services to share files over a network.

 

Client/ Client Computer: 

A client is a computer that connects to and uses the resources of a remote computer, or server. The term “client” may also be applied to computers or devices that run the client software or users that use the client software. For example, web browsers (Google Chrome , Opera, Firefox, etc.) are clients that connect to web servers and retrieve web pages for display. Email clients retrieve email from mail servers.

Upload: Upload means data or file is sent from your computer to other’s computer or server.

Download: Download means data or file is received in your computer from other’s computer or server.

Web Browser: 

A web browser, or simply “browser,” is an application software used to access and view websites. Browsers translate web pages and websites delivered using Hypertext Transfer Protocol (HTTP) into human-readable content.

Common web browsers include Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, and Apple Safari.

A web browser is not the same thing as a search engine, though the two are often confused. For a user, a search engine is just a website, such as google.com, that stores searchable data about other websites. But to connect to a website’s server and display its web pages, a user must have a web browser installed on their device.

 

Search Engine: 

Search engine is a software that allows Internet users to search for content via the World Wide Web (WWW). A user enters keywords into a search engine and receives a list of Web content results in the form of websites, images, videos or other online data. The list of content returned via a search engine to a user is known as a search engine results page. 

The first search engine ever developed is considered Archie, which was used to search for FTP files and the first text-based search engine is considered Veronica. Today, the most popular and well-known search engine is Google. Other popular search engines include AOL, Ask.com, Baidu, Bing, and Yahoo.
