Browsers
    Back to Top
A Browser is simply a program that allows you to 'browse' the Internet, such as Internet Explorer, Mozilla Firefox, Google Chrome, Opera, Apple\s Safari and the standard Android 'Browser', etc.. There are many different more Browsers available for all of the various Operating Systems. Most are fairly similar, but they all have their own layout, functions, settings and of course, advantages and disadvantages. Which one you choose is very much down to personal preference, but you should also take security into consideration. some browsers are safer than other and depending on what you use yours for, you may be advised to find one with better than average security. However, whichever one you use, by keeping your Browser up to date, by downloading and installing the latest version (usually done automatically for you, but check the settings to see that this is set), you will have all of the latest anti-hacking and anti-malware updates working in your favour!

Domain
    Web Hosting & Domains main page    Back to Top
A Domain is simply the allocated address of a website, such as 'sekureit.com'. This is the same as a personal address. It is not only the address, where people can mail messages to, using the @ symbol, in a standard email address, but also the place on the web where the files for the website 'live' and are stored. When you type in the address into the address bar of your browser, the Server 'serves' the content of the website page to your browser, in much the way that you might serve someone at a party a drink - they don't get everything in your house, only what you offer or what they ask for, i.e. the website's home page. If you want to own and run your own independent website, you will need to decide on and purchase a Domain Name. See 'Hosting'.

Hexadecimal
    Back to Top
Hexadecimal, often just stated as 'Hex', is a Number Base System, based on sixteen in our standard number base (Decimal, or base 10). Our standard number system is Decimal (Dec.), which is based on ten, meaning that you add another column when you get to ten. With Hexadecimal, you count up to sixteen (Dec.) in the first column using the numbers and letters 0-9 and A-F, then start a new column in the same way. So, F (Hex.) = 16 (Dec.) and 20 (Hex.) = 2x16 = 32 (Dec.). Hexadecimal hugely increases the amount of numbers that can be expressed with the same number of digits used in standard Decimal system and is far more convenient when dealing with very large number, as in IP Addresses and Mac Addresses.

Hosting
    Back to Top
Hosting is what an Internet Server does. It stores and provides web pages, videos, downloads and all of the other 'stuff' on the web to your computer, laptop or phone. If you want to run your own website, firstly you will need to decide on a domain name and a Top Level Domain. In the address 'Sekureit.com'. Sekureit is the Domain Name and .com is the Top Level Domain. Put together with the protocol (https://, www., etc.), they make up a URL, or 'Uniform Resource Locator'. Typing this into any Browser will get you to that website's home page. The next steps in getting your website hosted is to find a Hosting Company and then to design, code and upload your website to the Host Server. You can do this all yourself, or you can use software to put your website together, which is provided free by most Hosting companies. Alternatively, you can use a company which will generate and host your website using one of their templates and host it on a Sub-Domain on their servers, such as Wordpress Hosting with companies like WP Engine, SiteGround, DreamHost and Bluehost.

Internet
    Back to Top
The internet is the 'backbone' of the web, the network of servers (specialised, dedicated computers) and routers that connect everything on the 'web' together and translate website addresses into IP Addresses, that the Servers understand, allowing you to connect to anything and anyone on the web, from wherever you happen to be. Without the Internet infrastructure, there would be no 'Web'.

IP Address
    Back to Top
An IP Address is the actual address of a website, server, computer, or an other device on the web. When you type in an address, such as 'sekureit.com, or 'mysite.au', this is simply the user-friendly version of the address, or URL (Uniform Resource Locator), which Internet Routers then translate into an IP Address, so that it can be found in a routing table and your browser or other software directed to it. Because of the huge number of devices and sites, most have 'local' IP Addresses, below a Main Address. IP Addresses are in the format xxx.xxx.xxx, where each x will be replaced by a number or letter in the range 0-9 and A-F. These are hexadecimal numbers and increase the amount of numbers that can be expressed with the same number of figures used in standard Decimal system. See Hexadecimal for more information on this.

MAC Address
    Back to Top
A MAC (Media Access Control) Address should not be confused with IP Address. IP Addresses are assigned to Computers, Phones, Systems and Websites, whereas MAC Addresses are assigned to very specific hardware devices and these are permanent and do not change. For instance, you laptop or other device will be assigned an IP Address when you connect ot log onto a network or the internet, but inside your device, each and every hardware component that connects to a network of any sort will have it's own MAC Address to identify itself, such as your Wi-Fi Adapter, Your Ethernet Adapter, Bluetooth Adapter, erc.. Each of these have a unique number, which is given and 'burnt-in' (stored electronically) to that component at the time of manufacture. Due to the huge number of these components/devices, the numbers are very long, but by using Hexadecimal numbering system, trillions of devices can have unique devices with a manageable length number of just 12-digit digits.

Server
    Back to Top
A Server is simply a specialised computer for 'serving' web pages and other content to another computer or device, know as the 'client'. They run specialist software to do this, usually Apache (server software), PHP (code translation) and MySql (database software) plus some other software. They are also usually small 'card' computers, which are part of large racks, with many cards in one rack and many racks in an air-conditioned room, or rooms, as they generate a lot of heat! They usually run either Windows or Linux Operating Systems. When you own a website, it is stored and 'hosted' on one of these severs and 'served' to users on demand. You can turn your own computer or laptop into a server simply by installing the necessary software. If you have a Windows computer, look up 'WAMP' (Windows, Apache, MySql, Php), for Apple Mac, look up MAMP and for Linux, LAMP, though there are other options, such as Windows Home Server, Ubuntu Server and many others, as well as Server-specific Operating Systems.

Sub Domain
    Back to Top
A Sub-domain is simply a separate area of a website that is not normally accessible without a direct link, due to it being a separate domain which is 'below' the normal domain. A Subdomain is noticeable by it's URL, or address, which is the same as the main/normal address, such as 'sekureit.com' but is preceded by another name and a period (a 'full stop'), such as 'help.sekureit.com'. Business email addresses often use this format, as it is more secure.

Web
    Back to Top
The Web is the collection of Websites that reside on the Internet and also the Servers that the websites are 'Hosted' on. The Sever stores the files that comprise the website and 'Serve' the requested pages when someone 'Visits' that site.

WWW
    Back to Top
WWW is simply the acronym for 'World Wide Web' and all the websites and servers that host them, see 'Web',
