CDN Overview: A Content Delivery Network (CDN) is a network of distributed servers that caches content close to users, improving website performance, reducing bandwidth costs, enhancing availability, and providing security against attacks. CDNs enhance load times by minimizing distance to data centers and optimizing transfers, while ensuring reliability through load balancing and failover capabilities.
A domain name is a website's address used to access it via a browser, combining a business name with an extension (like .com). Key benefits of registering a custom domain include increased memorability, credibility, and branding. It consists of three elements: top-level domain (TLD), second-level domain (SLD), and third-level domain (subdomain). Choosing the right TLD affects perceptions and targeting audience. Domains can be registered through registrars, and differences between domain names and URLs are clarified. Tips for selecting a domain name emphasize uniqueness and memorability.
Domain name registrar: a business that facilitates domain name registration, leasing them from registries (which own the names). Registrars notify registries when a domain is sold and manage reservations, not ownership. They also protect user privacy and maintain security against attacks like hijacking. Cloudflare is one such registrar, offering transparent renewal costs.

DNS (Domain Name System) translates domain names (like example.com) into IP addresses, allowing users to access websites easily. It involves four servers: recursive resolver, root nameserver, TLD nameserver, and authoritative nameserver. DNS lookups typically involve 8 steps, with caching improving speed by storing past queries. Recursive queries require the resolver to find records, while iterative queries allow servers to provide referrals. DNS caching occurs at the browser and OS levels, enhancing performance.
FTP Overview: File Transfer Protocol (FTP) facilitates file transfers between servers and clients. Initially developed in the 1970s, it remains relevant for managing websites effectively. FTP operates via a client-server model, using separate control and data connections. Access requires authentication, and it supports various methods for transferring files, including dedicated FTP clients and web browsers.
Comparison with Other Protocols: FTP differs from HTTP's purpose (file transfer vs. web data) and security features; it's less secure than HTTP and SFTP. SFTP and FTPS offer encrypted file transfers, addressing FTP's security limitations.
Pros and Cons: FTP is user-friendly for transferring large files but lacks encryption, making it susceptible to interception. Everyday use cases include bulk file transfers, server interactions, and website management.
Conclusion: Despite its age, FTP is still a vital tool for file management, especially for web development. Many FTP clients support it for enhanced functionality and security.
A website is an online space for sharing information, showcasing ideas, and facilitating interactions, essential for personal, business, and educational purposes. Key components include domain names, web pages, web servers, and hosting. Types of websites vary from blogs to eCommerce and dynamic sites, each serving specific functions. Websites enhance brand competitiveness, expand audience reach, and support online sales, all while requiring regular maintenance and SEO optimization.
