The data transfer rate is very important because it regulates our devices and technologies we use. In general, the data transfer rate reflects changes and improvements in digital technologies, where newer systems, such as solid-state electronics, have resulted in much higher data transfer rates within only a few decades. Often, people mistake transfer rate with broadband, nevertheless, they are two different things working in slightly different ways.

The Download Speed is how quick you can download files from the web and how quick the Website loads. The download speed can be affected by a number of factors.

The Top Level domain name servers direct the query specific namerservers. There are Authoritative servers have the information in DNS records.

A DNS lookup, in a general sense, is the process in which a DNS record

Below I have described the few steps to provide the information about how the DNS works.

Web Address - can be defined as an address string containing the access protocol, domain name, and file or resource path which is normally used to specify the address of a web page, image, or any other document on the Internet. It specifies the path followed to reach files and documents on the internet.

Decentralized website address is something that integrates and incorporates the use of DNS services that are decentralized or unregulated. A DNS or Domain Name System is something that efficiently links human-readable site addresses – for example, www.ilovebitcoin.io with the Internet Protocol or a machine readable location of a DNS server hosting that particular site.

Before Server Load Balancing was a technology or a viable product, site administrators would and employ a load balancing process known as a DNS round robin. DNS round robin uses a function of DNS that allows more than one IP address to associate with a host name. Every DNS entry has what is known as an A record, which maps a hostname, such as www.example.com to an IP address, such as 111.222.333.444. Usually only one IP address is given to a hostname. With DNS round robin, it is possible to give multiple IP addresses to a host name distributing traffic more or less evenly to listed IP addresses. For instance, let’s say you had three web servers with IP addresses of 111.222.333.444, 111.222.333.445, and 111.222.333.446 that we wanted to share the load for the site www.example.com. The end result is that the traffic destined for www.example.com is distributed

The internet is based on ip addresses not domain names every we server requires a domain name system to translate domain names into ip addresses.

Web Server A Web server can refer to the hardware or the software which helps deliver content from the web which can be accessed through the internet. The most common types of web servers are used to host websites and also used to host gaming servers and also handling e-mails.

The other method that DNS provide mapping through it, is the recursive method, this type of service is done when the DNS server does not find the data or the related IP address in its memory so it will ask the authoritative DNS about the data and return it back to the user and store this

DNS is Domain Name Systems. It is where you put the name of the website on the URL bar instead of the IP address. Which then searches for it on the web. The first part of a domain name is “www.” Which stands for World Wide Web. The second part is the name of the company of the website, for example it could be google. The third part can be either “.com or co.uk”, the first part is www which means World Wide Web. The second part is the name of the company who owns that website. The third part is top level Domain which would be .com because it would tell you it’s coming from that company.

Bandwidth is the bit-rate of available information capacity, typically calculated in metric multiples of bits per second. Narrowband describes telecommunication that carries voice information in a narrow band of frequencies.

E.g. www.google.com. A server provides services in the name of the host, but hosts and servers do not have a one-to-one mapping. Sometimes, a port number can also follow host names. Well-known port numbers for a service are normally omitted from the URL. Most servers use the well-known port numbers for HTTP and HTTPS, so most HTTP URLs omit the port number. The hostname is further subdivided into following

An ISP (Internet Service Provider) is a company that provides internet servers with internet access facility and some other facilities such as virtual hosting. They are responsible for setting up a DNS and providing the users with a dynamic or static IP address.
