Explain how packet-switching contributes to efficient resource sharing in modern computer networks.
Explain how packet-switching contributes to efficient resource sharing in modern computer networks.
Packet switching allows multiple packets to share the same network link, this facilitates simultaneous communication between devices, optimizing resource utilization.
Describe the role of checksums in packet-switched networks and why they are important.
Describe the role of checksums in packet-switched networks and why they are important.
Checksums are used to detect and correct errors during data transmission by verifying the integrity of the packets. They help ensure data accuracy and reliability.
Explain the relationship between a 'node' on a network and its IP address.
Explain the relationship between a 'node' on a network and its IP address.
Each node has a unique IP address that is used to uniquely identify network nodes.
How do Internet Service Providers (ISPs) obtain IP addresses, and what is the role of regional Internet registries in this process?

Study Notes
- A network is a collection of computers and devices that send and receive data in real-time.
- Each device on a network is called a "node".
- Examples of nodes are computers, printers, and routers.
- Each node has a unique IP address.
- IP addresses uniquely identify network nodes.
- Internet Service Providers (ISPs) assign addresses.
- ISPs receive addresses from regional Internet registries.
- In North America, the American Registry for Internet Numbers (ARIN) distributes IP addresses.
- Internet Corporation for Assigned Names and Numbers (ICANN) regulates IP addresses.
Packet-switched Networks
- Modern computer networks are packet-switched.
- Data is broken into smaller packets in packet-switched networks.
- Each packet is processed independently.
- Each packet contains metadata, such as the sender and recipient's addresses.
- Multiple packets can share the same network link, allowing simultaneous communication between devices, for efficient resource sharing.
- Packets include checksums to detect and correct errors during transmission, ensuring data integrity.
