Wi-Fi is a wireless networking technology that allows devices to connect to a network without using cables. It uses radio waves to transmit data.
Bandwidth
Bandwidth refers to the amount of data that can be transmitted over a network connection in a given amount of time, usually measured in bits per second (bps). Higher bandwidth means faster data transfer speeds.
Latency
Latency is the delay in data transfer over a network connection, usually measured in milliseconds (ms). Lower latency is desirable for real-time applications like online gaming and video conferencing.
DNS (Domain Name System)
DNS translates domain names (like google.com) into IP addresses that computers can understand. It's essentially the phone book of the internet.
URL (Uniform Resource Locator)
A URL is the address of a resource on the internet, such as a web page or file. It includes the protocol (e.g., HTTP or HTTPS), domain name, and path to the resource.
HTTPS (Hypertext Transfer Protocol Secure)
HTTPS is a secure version of HTTP that encrypts data transmitted between your browser and the website. It uses SSL/TLS to protect your information from eavesdropping.
Security and Privacy Terminology
Firewall
A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predefined security rules. It helps protect your computer from unauthorized access.
Antivirus Software
Antivirus software detects, prevents, and removes malicious software, such as viruses, worms, and Trojans.
Malware (Malicious Software)
Malware is a general term for any software designed to harm or disrupt a computer system. It includes viruses, worms, Trojans, ransomware, and spyware.
Phishing
Phishing is a type of online scam where attackers attempt to trick users into revealing sensitive information, such as passwords, credit card numbers, and social security numbers, by disguising themselves as a legitimate entity.
VPN (Virtual Private Network)
A VPN creates a secure, encrypted connection over a public network, such as the internet. It masks your IP address and protects your online activity from prying eyes.
Encryption
Encryption is the process of converting data into an unreadable format, making it secure from unauthorized access. It's like scrambling a message so only someone with the key can read it.
Two-Factor Authentication (2FA)
2FA is a security process that requires two different authentication factors to verify a user's identity, such as a password and a code sent to their phone.
