| Question | Answer |
|---|---|
| Packet | The basic unit of data transported across a network; contains data and metadata (like destination IP). |
| Internet | A global, open network of computing devices communicating using the same protocols. |
| World Wide Web (WWW) | The part of the Internet that consists of content (like HTML) shared using the HTTP protocol. |
| IP (Internet Protocol) | The protocol used for addressing and routing data; uses IP addresses to uniquely identify devices. |
| DMS (Domain Name System) | Translates a website's human-readable name (e.g., google.com) into its numerical IP address. |
| TCP (Transmission Control Protocol) | A reliable protocol that ensures all packets arrive in order and without loss (handles re transmission and reordering). |
| UDP (User Datagram Protocol) | A faster, unreliable protocol that does not guarantee delivery or order and does not re transmit lost packets. |
| Latency | The time difference between when data is sent and when it is received. |
| Bit Rate | The number of bits of data that are sent each second. |
| Bandwidth | The maximum bit rate (data speed) a system is capable of achieving. |
| Redundancy | Having multiple paths connecting each server so packets can be transmitted through various routes. |
| Fault Tolerance | The ability of a network to continue working even if one or multiple components are failing. |
| TLS (Transport Layer Security) | A cryptographic protocol that provides secure communication over a network. |
| HTTPS (Hypertext Transfer Protocol Secure) | The secure version of HTTP; uses TLS to encrypt the connection. |
| Symmetric Encryption | Uses a single, secret key for both encrypting and decrypting data |
| Asymmetric Encryption | Uses two paired keys: a public key for encryption and a private key for decryption (more secure). |
| Digital Certificate | Proves the ownership of an encryption key (specifically a public key) to verify identity. |
| Scalability | The ability of a system (network) to expand and handle growth in size and demand. |
| Digital Divide | The lack of access to the internet (and digital resources) for some individuals or communities. |
| IP Address Hierarchy | The organization where the first sequence of bits represents the network and the final bits represent the individual device (node). |
