1. Internet
2. LAN​

Answer 1

1. The Internet, sometimes called simply "the Net," is a worldwide system of computer networks -- a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers)

2. A local area network (LAN) is a computer network in a small area like a home, office, or school. Many computers can be connected to share information and Internet connections. Most LANs use Ethernet to connect together. LAN topologies tell you how ROM devices are organised.

Answer 2

Answer:

• Internet = The Internet is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s.
• Lan = A local-area network (LAN) is a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.
