VPN

 What is VPN?

According to Attila Tomaschek, Moe Long (2024) “Put simply, a VPN is software that establishes a secure connection between your computer and the internet by running your internet traffic through an encrypted tunnel to a server in a remote location.” (Attila Tomaschek, 2024)

Personally, I view a VPN as a kind of shield that protects my internet connection. It gives me peace of mind knowing that when I use it, my traffic passes through an encrypted tunnel, preventing third parties from seeing what I'm doing online. I also find it useful that it allows me to connect from remote locations, which can improve my privacy or give me access to region-restricted content. In short, for me, a VPN is a key tool for browsing with greater security and freedom.

TLS

  What is TLS? Based to the Cyber Security Agence of Singapure (2025) “Transport Layer Security (TLS) is a cryptographic protocol that provides end-to-end security of data sent between applications over the Internet.” (Cyber Security Agence of Singapure , 2025) This quote perfectly highlights the importance of TLS in protecting our data online. I find it incredible how this protocol acts almost invisibly, ensuring that the information I send from an app or browser arrives securely at its destination. Personally, knowing that technology like TLS exists gives me more confidence when using online services, as it protects my data from potential attacks or unauthorized access. For me, it's an essential part of digital security in today's world.

Connectivity

What is connectivity? According to 19usb10137 (N.D) in Brainly “Connectivity- is the capability of your personal computer to share information with other computers.” (19usb10137, s.f.) In my opinion, connectivity, as mentioned in the quote, does involve a personal computer's ability to exchange information with other devices. This communication can occur through local area networks (LANs), wide area networks (WANs), the Internet, Bluetooth, Wi-Fi, among others. However, connectivity today encompasses much more than just "sharing information." It also refers to the continuous and fluid interaction between systems, cloud services, remote servers, mobile devices, and IoT (Internet of Things) sensors.
