Answer:
1. Internet service provider (ISP)
2. Protocols.
3. IP address.
4. Domain name server (DNS)
5. Packets.
6. Routers.
7. Redundancy.
Step-by-step explanation:
Individuals connect to the Internet through an internet service provider (ISP) allowing them access to the system. The rules on the Internet for how messages are addressed and passed on are called protocols. A protocol can be defined as a standard set of rules established by the regulatory agencies to determine how data are transmitted from one network device to another.
Each device on the internet has a unique numeric address called an IP address, which can be looked up automatically using a domain name server (DNS), which is like a giant address book.
Each message is broken up into small pieces called packets that are sent individually which makes the Internet more reliable. Since packets often arrive out of order, they include information about the order in which they should be arranged as well as who the sender and receiver are.
Packets are guided through the internet by routers. Having multiple paths or redundancy makes the Internet more reliable and allows it to keep growing as more people and devices are connected to the system.
