Web browser
a system of interconnected documents and other resources, linked by hyperlinks and URLs, and accessible through the internet.
World Wide Web (WWW)
is the fundamental set of communication protocols used for transmitting data over the internet and most computer networks. It defines how data is packetized, addressed, transmitted, routed, and received.
TCP/IP (Transmission Control Protocol/Internet Protocol)
a unique numerical label assigned to each device
connected to a computer network that uses the Internet Protocol for communication.
IP address (Internet Protocol address)
- A protocol for transferring data between a web browser and a web server.
- Data is sent in plaintext, making it vulnerable to hackers.
- Uses port 80 by default.
- Does not use encryption, making it less secure.
HTTP (Hypertext Transfer Protocol)
- A more secure version of HTTP that uses SSL/TLS encryption to protect data.
- Ensures confidentiality, integrity, and authentication.
- Uses port 443 by default.
- Encrypts communication, making it much safer for sensitive transactions (e.g., banking,
login credentials). - Websites with HTTPS have a padlock icon in the browser address bar.
HTTPS (Hypertext Transfer Protocol Secure)
a global network of interconnected computers and devices that communicate using standardized protocols (such as TCP/IP). It enables people to share information, access websites, send emails, stream videos, and much more.
Internet
a private, secure network used within an organization to facilitate
communication, collaboration, and information sharing among employees. It functions like a private version of the internet but is restricted to authorized users within the organization.
Intranet
a private network that allows authorized external users, such as customers, suppliers, or business partners, to access certain parts of an organization’s internal network.
