2)The internet is when we connect computers together from anywhere over the world through routers and servers. Three popular uses for the internet are communication,research and education.

A: Internet: Internet means the network of networks that connected to all networks around the world. For an instance, if you send an email or a message using your mobile phone, then your mobile phone uses internet.

A LAN is a ‘Local Area Network’. It is a small network of computers most often

It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.

LANs standards and protocols are Ethernet, IEEE 802.2 [IEEE 802.3, 100BaseT, Token Ring/IEEE 802.5 and FDDI.

Hypertext Transfer Protocol, HTTP, is a primary standard which lays the foundation for which the World Wide Web is built upon. HTTP’s main purpose is to receive requests for and deliver content on the Web. The Internet Engineering Task Force’s, IETF, Request for Comments, RFC, 7230 describes HTTP as “.. a stateless application level protocol for distributed, collaborative, hypertext information systems.” (IETF 14). Overall it is essentially the main way of distributing web pages and is what the http in the url of links stands for.

Scientists in the same year began to create what is known as today as the Modern World Wide Web, the emergence of the modern Internet today. Several online web servers held information on pages of text known as websites, in which they each had their own website name to access (History of the Internet). A new application called the web browser was created in order to access all of the web pages available on the internet to the public. The way the information was presented on the web page was with a hypertext markup language (HTML); this would become a standard format to display informational text (Goel, Tarun). A URL link was also introduced on the web browser as an address to access web pages for the public. The result of the internet had changed how people have done research to access more information and how people have communicated with one another (Goel, Tarun).

Local Area Network or LAN for short is the term used for computer networks located at a single location such as a small business located at a singular location. They are generally used for businesses, organisations and the likes to transfer data amongst their systems as opposed to transferring data to outside of their location. A LAN typically will rely on wired connections due to the benefits of increased security and speed, but a network called a WLAN exists, which is a Wireless Local Area Network and this may prove useful for those who come to work using mobile devices such as laptops, phones, etc. WLANs are simply local area networks that consist solely of wireless connections using a wireless access point (WAP) as the central hub. However, LANs can be a mix of both wireless and wired.Typically in a LAN, systems connected to the network are able to share resources among each other, send data to servers and use peripherals such as printers, scanners &

World Wide Web – Also known as WWW, which has a vast of data, websites, files and everything that would be connected to the internet. It is the structure for the servers that supports all kinds of formatted documents. The formatted documents are in HTML (Hypertext Mark-up language) which would be able to link in other documents such as graphics audio and video files. This is efficient as the user can go from document to another. Web browsers such as Google Chrome, Safari, and Internet Explorer allow World Wide Web to be operated so that the websites are easily accessible.

LAN refers to Local Area Network. This is a network of computers in small areas. It is usually used in organizations, schools or even at home. A Local Area Network can be created with Ethernet cables and its components or via wireless technology. A Local Area Network has reduced security threats to its data in that for a person to access the data, they need to be within the small region with coverage which is mostly within the company’s or organization’s premises. As a result, this reduces the risk of unauthorized persons accessing the data.

There are several types of network infrastructures that are commonly used within healthcare organizations. The most commonly used network is the Local Area Network (LAN) that is used to connect digital devices and computers within the building of the healthcare organization. In addition to this, WLAN and WAN are used to spread the network when different parts of the building are to be connected or different departments in an organizational complex are to be connected.

A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.

Everyone who used the web undoubtedly have seen URL as a sight word in the internet world, and also have used URLs to get web pages and access websites. Actually, most of people term URL as “website address” habitually and think of an URL as the name of a file on the World Wide Web. If we consider the web world as the same as the real world, then URL would be the very unique physical address of every build on the earth that helps people to locate the accurate place. However, it is not the entire understanding of URL. URLs could also lead to other resources on the web, such as databases queries and command output.

A universal resource locator, includes the protocol (ex. HTTP, FTP), the domain name (or IP address), and additional path information (folder/file). On the Web, a URL may address a Web page file, image file, or any other file supported by the HTTP protocol.

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.
