Introduction and Course Sponsorship
The video is a continuation of Chapter 2 of the HTML and CSS course. The instructor introduces the importance of having the course material accessible and announces sponsorship from Record, an organization offering various technology courses.
Course Sponsorship by Record
- Record is sponsoring the course to prepare students for the job market.
- They offer courses ranging from basic Windows and Office training to advanced topics like Internet of Things and mobile app development.
- Students can join the platform for free by following the instructions provided in the video.
How Websites are Viewed
The instructor addresses a common question about how other people can view websites created by students.
Exclusive Video for Addressing Website Viewing
- Students can refer back to Chapter 2 in their course material for an exclusive video that answers this question.
- It is recommended to take notes during the video to better understand the process.
Understanding Internet Functionality
The instructor revisits a graph explaining how websites function on the internet, with modifications made to include additional clients and a DNS server.
Graph Explanation
- A graph illustrating internet functionality was previously shown in a previous lesson.
- Modifications have been made to include more clients, representing devices connected to the internet, as well as a DNS server.
- Clients can be personal computers or other devices connected to the internet.
- The DNS server helps translate domain names into IP addresses.
Website Files on Servers
This section explains where website files are stored and how they are accessed through URLs.
Accessing Website Files on Servers
- In previous lessons, it was explained that website files, such as HTML and CSS, are stored on servers.
- To access a website, users need to type the URL (e.g., www.example.com) into their browser.
- The DNS server translates the domain name into an IP address, allowing access to the website's files.
Working with Website Files Locally
This section discusses how students will work with website files on their own computers before uploading them to a server.
Working with Website Files Locally
- Students will start by writing HTML and CSS code on their own computers.
- They will have full access to these files and can view the website locally without any issues.
- However, others cannot access the website because it is not hosted on a server.
Storing Website Files Online
This section explains how websites can be made accessible online by hosting them on a server.
Making Websites Accessible Online
- To make websites accessible online, they need to be hosted on a server.
- When websites are hosted on a server, they can be accessed by others through URLs or IP addresses.
- Without hosting, websites remain confined to the local machine and cannot be shared with others.
The transcript provided does not cover all sections of the video.
Understanding DNS and Server Access
In this section, the instructor explains the importance of DNS (Domain Name System) and server access for hosting websites.
DNS and Server Access
- DNS is necessary to access a website as it provides the unique name associated with an IP address.
- To access files on a server, both HTML and CSS need to be hosted on the server.
- A URL acts as a bridge between the user and the server, allowing access to the website.
- A domain name is required to provide an address for others to access your site.
- Hosting files at home is not recommended due to technical challenges and security risks.
- Domains are unique names, and if a domain already exists, it cannot be used again.
- Domains can be free or paid, with paid domains requiring annual payment.
Importance of Domain and Web Hosting
This section highlights the significance of having a domain name and web hosting for building websites.
Domain and Web Hosting
- A domain is essential for providing an address for others to access your website.
- Web hosting refers to having a space where you can store your website files.
- Free web hosting options are available but come with limitations.
- Professional websites often require paid web hosting services that offer more features.
- Choosing a suitable web hosting service depends on factors like storage space, memory, resources, databases, etc.
Types of Top-Level Domains (TLDs)
The instructor explains different types of top-level domains (TLDs) used in URLs.
Types of TLDs
- TLD stands for top-level domain and represents the last part of a domain name (e.g., .com, .org).
- There are two types of TLDs: gTLD (generic top-level domain) and ccTLD (country code top-level domain).
- The choice of TLD depends on personal preference and availability.
- Free domains may have limited options compared to paid domains.
Understanding Web Hosting
This section provides an overview of web hosting and its importance for storing website files.
Web Hosting
- Web hosting is like having a storage space for your website files.
- Free web hosting options exist but come with limitations.
- Professional websites often require paid web hosting services for better performance and features.
- Choosing the right web hosting service involves considering factors like storage space, memory, resources, databases, etc.
Importance of Choosing the Right Web Hosting
The instructor emphasizes the significance of selecting the appropriate web hosting service.
Importance of Choosing the Right Web Hosting
- While a domain name is important, choosing the right web hosting service is crucial.
- Factors such as reliability, performance, support, and security should be considered when selecting a web host.
- Different web hosts offer varying levels of quality and services.
Understanding URLs
This section explains what URLs are and their components.
Understanding URLs
- A URL (Uniform Resource Locator) is an address that points to a specific resource on the internet.
- URLs consist of different parts that serve specific purposes.
- The first part is the protocol (e.g., http:// or https://).
- The second part is the domain name (e.g., www.example.com).
- Additional parts can include paths or query parameters depending on the specific resource being accessed.
Understanding Domain Names and URLs
In this section, the speaker explains the components of domain names and URLs, including subdomains, top-level domains, country codes, and paths.
Components of a Domain Name
- A domain name consists of multiple parts: the www (subdomain), the main domain name, and the top-level domain (TLD).
- There are different types of TLDs:
- Generic TLDs (gTLD) represent commercial or educational institutions.
- Examples include .com, .net, .org.
- Country code TLDs (ccTLD) represent specific countries.
- Examples include .br for Brazil, .us for United States.
Understanding URLs
- A URL is composed of various elements: protocol, subdomain, domain name, path.
- The protocol indicates how data should be transmitted over the internet (e.g., HTTP or HTTPS).
- The subdomain is an optional part that appears before the main domain name.
- The domain name represents the website's address.
- The path refers to additional information after the domain name.
- Identifying components in a URL:
- Protocol: http or https
- Subdomain: www or any other custom subdomain
- Domain Name: main website address
- Path: additional information after the domain name
