A domain name is the name of your website that corresponds to a numeric IP address. Without going into technical details, a domain name is the text that a user types into a browser window to access a certain website.
Domain Name
A domain name is the name of your website that corresponds to a numeric IP address. Without going into technical details, a domain name is the text that a user types into a browser window to access a certain website. For example, Google’s domain name is ‘google.com.’ A website’s actual address is a complex numerical IP address (e.g. 42.21.244.32), but thanks to DNS, users may type in human-friendly domain names and be directed to the websites they want. IP addresses are a set of numbers used by computers to identify each other. Humans, on the other hand, have a hard time remembering long strings of numbers. As a result, domain names were created and are now used to identify entities on the Internet instead of IP addresses. A domain name can be any combination of characters and numbers, and it can use various domain name extensions, such as .com, .net, and others.
Sub Domain
A subdomain is a component of your primary domain name that is separate from it. Subdomains are used to organize and browse your website’s various sections. On your primary domain, you can create many subdomains or child domains. A subdomain name is a piece of information that is appended to the beginning of the domain name of a website. It enables websites to divide and arrange material for a specific purpose, such as a blog or an online store, from the rest of the site.
Let’s use shop.mywebsite.com as an example. In this case, the subdomain is ‘shop,’ the primary domain is ‘mywebsite,’ and the top level domain is ‘.com’. You can use any text as your subdomain, the simpler the name the better so it’s easier to remember.
A domain name usually consists of two parts: The top-level domain (TLD) is the extension of the domain name, such as.com or.org, while the second-level domain (SLD) is the distinctive portion of the domain name, usually a business or brand name. In the case of google.com, the TLD is com and the SLD is google.
The subdomain is the part of the URL that comes before the SLD. www, which stands for World Wide Web, is the most frequent subdomain. The homepage and the most significant pages of a website are located on this subdomain.
Hosting
Web hosting is defined as a secure location for storing internet content. All of the code, images, videos, and text that make up a website must be saved somewhere. We wouldn’t be able to access content on the internet without a reliable digital repository. As a result, hosting is one of the most important aspects of building an online presence for anyone, from large corporations to individual accounts.
Web hosting allows users to store content elsewhere, lowering local storage costs and the physical footprint associated with it. It also makes it easy to create a long-lasting web presence, thanks to features like security and support backups.
Although some web hosting is done locally on personal computers or servers, cloud-based third-party companies are increasingly popular. You should be able to locate a wide choice of both free and paid hosting solutions to examine once you begin your search.
Secure Sockets Layer (SSL)
Secure Sockets Layer or SSL is a common security protocol for establishing an encrypted link between a server and a client, typically a web server and a browser, or a mail server and a mail client (e.g., Outlook). TLS, or Transport Layer Security is the successor technology of SSL but not used as often.
SSL enables safe transmission of sensitive data such as credit card details, social security numbers, and login credentials. Data exchanged between browsers and web servers is usually transferred in plain text, leaving you open to eavesdropping. An attacker can see and utilize information if they can intercept all data transmitted between a browser and a web server.
SSL is a security protocol to protect the transmission of data. Protocol guidelines specify how the security algorithms should be applied. The SSL protocol, in this scenario, determines the encryption variables for both the link and the data being transmitted. The SSL protocol can be used by all browsers to communicate with secure web servers. However, in order to establish a secure connection, both the browser and the server require an SSL Certificate.
DNS (Domain Name Servers)
The Domain Name System (DNS) is considered the Internet’s phone book. DNS is responsible for determining the right IP address for domain names such as ‘google.com’ or ‘nytimes.com’ when users type them into web browsers. The addresses are then used by browsers to communicate with origin servers or CDN edge servers in order to retrieve website data. DNS servers, which are systems specialized to responding DNS queries.
The Domain Name System (DNS) is a database of domain names and IP addresses that helps browsers determine the correct IP address for a hostname URL. When we go to a website, we usually type the domain name into the web browser, such as cdnetworks.com, wired.com, or nytimes.com. However, in order to load content for a website, web browsers must know the specific IP addresses. The DNS is what converts domain names to IP addresses so that the website’s server can provide the correct resources.
A Records
An A Record connects a domain name to the IP address (Version 4) of the computer that hosts it. The IP address of a machine connected to the internet is determined by the A record, which uses a domain name. Address is represented by the letter A in the A Record.
The address you type when visiting a website, sending an email, connecting to Twitter or Facebook, or doing nearly anything else on the Internet is a string of words joined by dots. Enter www.dnsimple.com, for example, to get to the DNSimple website.
The IP address 208.93.64.253 is referenced by the A Record on our name server. This means that a request to www.dnsimple.com from your browser will be sent to the server at IP address 208.93.64.253.
A Records can be used for a variety of purposes, including providing redundancy and fallbacks by employing numerous A records for the same domain. Additionally, many names could point to the same IP address, in which case each would have its own A Record. RFC 1035 specifies the DNS A record.
CNAME
A canonical name (CNAME) record is a simple mapping of one hostname to another or to a fully qualified domain name (FQDN). You might think of it as the DNS record’s “Master of Disguise.” While it doesn’t actually hide anything, it does allow you to establish aliases for your primary domain.
When a domain or subdomain is an alias of another domain, the ‘canonical name’ (CNAME) record is used instead of an A record. CNAME records must always point to a domain, not an IP address. Think of it like a scavenger hunt in which each clue leads to the next, and the last clue leads to the treasure. A CNAME record for a domain is similar to a clue that can lead to another clue (another domain with a CNAME record) or the prize (a domain with an A record).
Consider the case of blog.example.com, which has a CNAME record with the value ‘example.com’ (without the ‘blog’). This means that when a DNS server encounters the DNS records for blog.example.com, it initiates a second DNS lookup for example.com, returning the IP address of example.com via it’s A Record. We’d say that example.com is the canonical name (or actual name) of blog.example.com in this scenario.
When a site has subdomains like blog.example.com or shop.example.com, such subdomains will frequently have CNAME records pointing to the root domain (example.com). Only the DNS records will change if the host’s IP address changes. All CNAME records will follow whatever changes are made to the root domain if a record for the root domain is modified.
A common misunderstanding is that a CNAME record must always resolve to the same website as the domain it points to, however this is not the case. Only the same IP address as the root domain is referenced by the CNAME record. The web server will handle the URL appropriately once the client reaches that IP address. For example, blog.example.com could have a CNAME that links to example.com, pointing the client to the IP address of example.com. But when the client actually connects to that IP address, the web server will look at the URL, see that it is blog.example.com, and deliver the blog page rather than the home page.
MX (Mail Exchange) Records
A DNS mail exchange or MX record directs email to a mail server. According to the Simple Mail Transfer Protocol, the MX record specifies how email messages should be delivered (SMTP, the standard protocol for all email). An MX record, like a CNAME record, must always point to a different domain.
An MX (mail exchange) Record is a DNS file entry that indicates the mail server for a domain’s email. To receive email at your domain, you’ll need to set up an MX record.
Shopping Cart
On an eCommerce site, a shopping cart is a piece of software that enables purchasing a product or service. An online shopping cart is software that allows users to choose products and purchase them via the internet.
In a physical store, a customer could browse, select a product from the shelf, then proceed to the checkout counter to complete the transaction. Alternatively, they could push a cart around the store collecting multiple items before checking out.
Customers need a way to replicate this experience on an e-commerce platform. They can choose things and store them in a virtual cart using an online shopping cart on their computer or mobile device. Once they are ready to checkout they can pay online.
WordPress
What is WordPress? WordPress is the most popular and easiest way to create your own website or blog. WordPress is responsible for 43.3 percent of all websites on the Internet. WordPress is likely to power more than one-fourth of the websites you visit.
WordPress is an open-source content management system released under the GPLv2 license, which means that anybody can use or change the WordPress software for free. A content management system (CMS) is a technology that allows you to manage critical components of your website, such as content, without having to know how to code.
As a result, WordPress makes it possible for anyone to create a website, even if they aren’t programmers.
Any website that uses WordPress as its content management system (CMS) is referred to as a WordPress website. Both the backend, the interface where a user logs in to make changes or add new material, and the frontend, the interface where a user views the website, are both powered by WordPress.
FTP (File Transfer Protocol)
FTP (File Transfer Protocol) is a system used for communicating and transferring files between computers connected to the internet via a TCP/IP (Transmission Control Protocol/Internet Protocol) network. Users who have been authorized access to the File Transfer Protocol server (also known as FTP host/site) can receive and transfer files.
