Networking

Networking

1. Wifi

   • Wifi is whats needed to connect you to the internet
     • A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. A data packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node.

2. The cloud

   • a visible mass of condensed watery vapour floating in the atmosphere, typically high above the general level of the ground
   • the way in which constituent parts are interrelated or arranged

3. WAN

   • A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks LANs

4. LAN

   • A local area network (LAN) is a network that connects computers and other devices in a relatively small area
     • the process of converting information or data into a code, especially to prevent unauthorized access.
   • A local area network (LAN) is a network that connects computers and other devices in a relatively small area, typically a single building or a group of buildings. Most LANs connect workstations and personal computers and enable users to access data and devices (e.g., printers and modems) anywhere on the network
     • denoting a computer system in which a central server provides data to a number of networked workstations.

5. IP Adress

   • a unique string of numbers separated by full stops that identifies each computer using the Internet Protocol to communicate over a network.

6. With guided transmission media, the waves are guided along a physical path; examples of guided media include phone lines, twisted pair cables, coaxial cables, and optical fibers. Unguided transmission media are methods that allow the transmission of data without the use of physical means to define the path it takes

7. When you enter a URL into your Web browser, your DNS server uses its resources to resolve the name into the IP address for the appropriate Web server. See more computer networking pictures. If you've ever used the Internet, it's a good bet that you've used the Domain Name System, or DNS, even without realizing it.

8. A virtual private network (VPN) is a network that is constructed using public wires — usually the Internet — to connect remote users or regional offices to a company's private, internal network.

   • A network host is a computer or other device connected to a computer network. A network host may offer information resources, services, and applications to users or other nodes on the network. A network host is a network node that is assigned a network address.
     • WAP (Wireless Application Protocol) is a specification for a set of communication protocols to standardize the way that wireless devices, such as cellular telephones and radio transceivers, can be used for Internet access, including e-mail, the World Wide Web, newsgroups, and instant messaging.
       • a data or communication network in which all nodes are independently connected to one central unit.
         • Protocol, in computer science, a set of rules or procedures for transmitting data between electronic devices, such as computers. In order for computers to exchange information, there must be a preexisting agreement as to how the information will be structured and how each side will send and receive it.
