Hardware And Software Components Which Enable The Internet And Web Essay

But how does it work? The internet, based on the concept of “packet switching”, involves the travelling of small packets of data over one or more networks (Frenzel, 2013). This can be compared to “electronic postcards”, meaning that “a computer generates a piece of data and flings it into the net, just like the postal system, except 100 million times faster” (Cerf, 2013). This concept allows one computer to speak to many different computers around the network by sending out these “electronic postcards”. However, before these networks can work seamlessly together, they must use a common protocol, or set of rules for transmitting and receiving these packets of data. There are several protocols currently in use, including the OSI Model, the TCP/IP Model, UDP, HTTP, and FDP (Mitchell, 2014), but the most commonly used is Transmission Control Protocol/Internet Protocol (TCP/IP) (Gilmer, 2011). Even as early as 1977, TCP/IP was being used by other networks to link to ARPANET (Kozierok,

A web server is a PC that opens pages on a browser on request. It sends the web address of the page that has been requested to the web browser. They have an IP address and possibly domains and are essential for an ecommerce because ecommerce is online and a web server is what you need to surf the web.

Web Server: A webserver is a Hardware device used to host an eCommerce website. The server supports the entire content of the website such as HTML files, Data bases and Image Files. Web Servers will run on operating systems such as Windows or Linux and will use web server software to manage access requests to the website. Webservers are similar to PC’s however they have faster processors and more memory making it much more powerful.

The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems.[1] HTTP is the foundation of data communication for the World Wide Web.

The OSI (Open System Interconnection) model is a set of specifications that allow computers around the world to openly communicate. It is pivotal to understanding and developing computer to computer communications in a network. Each layer plays a role in the process of sending and receiving data. The application layer is the top layer (layer seven) it promotes communication between programs and lower-layer network services. The services at this layer allow the network to decipher a program's request and the program to decipher data sent from the network. The Application layer protocols, programs handles formatting, procedure, security, synchronization, and any other requirements with the network. The Presentation Layer (layer 6) acts as a translator. For instance these protocols decode the jpg/jpeg files sent within the Web server’s HTTP response. So, in the last step (the Application layer) we enter the Web address and it took us to the Web site. This step allows us to see the images and content of the site. The Session Layer (layer 5) regulates and controls the communication between two nodes on the network. It is an ongoing exchange of data between the two and keeps the connection between them for the duration. It keeps the communication secure, detects whether or not the communication has been cut off and if it has it determines where to restart the

Transmission Control Protocol/Internet Protocol (TCP/IP) are the basic communication protocols, which were designed to provide low level support for internetworking. This term is generally also used to refer to a more generalised collection of protocols developed by the internet community and U.S. Department of Defence.

Server: This is a computer that is designed to carry out specific functions at the request of other computers they’re connected to a network and direct the information stored on the network to clients, for example a web server will run software that receives requests from clients and then processes the request and delivers an output using HTML.

6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?

A web server is computers otherwise gathering of computers that are used to deliver a web pages and other information to multiple users within the server.

A web hosting company allows business big and small, also individuals to make their websites accessible on the internet over the WWW (World Wide Web) hosting companies provide space on a server, this can be rented space or the actual server itself can be owned by the client. Everything that is stored at a data centre sits on a server, a server is basically a powerful pc that is capable of storing different data, or websites, that are then accessible through the network of the internet.

The TCP/IP protocols are the heart and soul of the Internet, and they describe the fundamental rules that govern all communications in the network. The original address system of the Internet is Internet Protocol version 4 (IPv4). The Internet Engineering Task Force (IETF) developed IPv6 to deal with the long-anticipated problem of IPv4 address exhaustion. However, IPv6 is not foreseen to supplant IPv4 instantaneously.

The internet matured in the 1970's as a result of the Transmission Control Protocol/Internet Protocol (TCP/IP), which is sill used today. It was adopted by the U.S. Department of Defense in 1980, and universally adopted in 1983. The usage of TCP/IP is what unites all elements of the net. Both public domain and commercial implementations of the roughly one hundred protocols of the TCP/IP protocol suite became available in the 1980's. During the early 1990's, Open Systems Interconnection (OSI) protocol implementations also became available by the end of 1991, the Internet has grown to include some 5,000 networks in over three dozen countries, serving over 700,000 host computers used be over 4,000,000 people. By December 1996, about 627,000 Internet domain names had been registered and now there are more than 30 million registered.

Over the next 10 years, we will see a change in technology, and the Internet. Things will continue to progress, and fundamental changes will easily be defined. Technologies have revolutionized how people spread and consume information; these changes will redefine who we are as consumers, merchants, and individuals. With the expansion of computers and the Internet connectivity, people are able to share more of their lives with family and friends. Technology has offered the world so many different services, which include emailing, instant messaging, search engines, blogs, and Wikipedia. These services have changed the way we communicate with others, our knowledge, and the way we conduct business. With the increasing usage of the Internet, developers continue to find ways to improve technology and the way we utilize the Internet. Technology has a wide range of different aspects and concepts, which includes protocols. There has to be rules, and objectives in any and everything we do, and protocols governs communications, errors, detections, messages, and speed. There are three technology concepts behind the Internet, and they are packet switching, Transmission Control Protocol/Internet Protocol (TCP/IP) communications

Web servers are compute systems that program and dispenses web pages as they are requested (they have an IP address). A web server is basically what a program or website is ran off of and depending on how good the servers are depends on how fast the programs are. The main use of a web server is to store, process and deliver web pages to clients. Another thing it is used for would include the configuration log file settings, including where the log files are saved, what data to include on the log files and other log file settings. As well as the ability to configure website security. An example of this would be user accounts that are or aren 't allowed to view the website which also means the IP addresses that are or aren 't allowed to view the website as well. Also creating an FTP site; an FTP site allows users to

Well-known communications protocols are Ethernet, a hardware and Link standard that is ubiquitous in local area networks, and the Internet Protocol Suite, which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.
