Across
- 4. a unique, globally visible identifier assigned by your Internet Service Provider (ISP) to your network (usually your router) that allows it to communicate with other devices and networks across the internet
- 6. a collection of LANs
- 8. a logical identifier (0-65535) that specifies a particular application or service on a device, directing incoming network data to the correct software
- 9. a unique numerical label assigned to every device on a computer network
- 10. the arrangement of devices (nodes) and connections (links) in a computer network, defining how data flows between them
- 12. the latest standard for assigning unique addresses to internet-connected devices, developed to solve the shortage of addresses in the older IPv4 system
- 13. a unique, internal number assigned to devices (like computers, phones, printers) on a local network (home, office) that isn't directly accessible from the public internet
- 14. a restricted, private network that limits access to authorized users or devices, preventing external connections, often using firewalls and proprietary tech, to maintain control
- 15. a network setup where devices connect in a circular loop, with each device linked to exactly two neighbors
- 18. the internet's phonebook, translating human-friendly domain names into machine-readable IP addresses
- 19. a virtual communication endpoint on a device, identified by a number (0-65535), that directs incoming and outgoing network traffic to specific software applications or services, allowing multiple programs (like web browsers and email clients) to use a single network connection simultaneously
Down
- 1. the process of forwarding data packets between different networks, acting like a postal service for the internet, where routers read a packet's destination IP address and use routing tables to find the most efficient path (or "hop") to send it closer to its final destination, enabling communication across the global network
- 2. a standardized set of rules and conventions that dictate how data is formatted, transmitted, and received between devices
- 3. a conceptual, seven-layer framework standardizing network communication, allowing diverse systems to talk by breaking down data flow into distinct functions
- 5. a system of two or more interconnected computing devices that communicate and share data, resources, and services
- 7. a network setup where every device (node) connects individually to a single central point
- 9. the foundational system that assigns unique numerical addresses to devices on the internet, allowing them to communicate, using a 32-bit system
- 11. uses open standards, APIs, and commoditized hardware/software**, allowing different vendors' components to interoperate
- 16. a company that gives individuals and organizations access to the internet
- 17. a collection of computers and devices connected within a small, specific area like a home, office, or campus, allowing them to share resources such as printers, files, and a single internet connection via technologies like Ethernet or Wi-Fi, and enabling high-speed, local communication.
