BASIC NETWORKING
NETWORKING 101
WHAT IS A NETWORK??
A computer network (or data network) is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet. (WIKIPEDIA.COM)

NETWORKING DEVICES:
QUESTION:
WHAT IS THE DIFFERENCE BETWEEN A HUB AND A SWITCH??
NETWORKING DEVICES (con't)
HUB
HUB: is a hardware device that relays communication data. A hub sends data packets (frames) to all devices on a network, regardless of any MAC addresses contained in the data packet.
SWITCH
SWITCH: computer networking device that links network segments or network devices. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (layer 3) and above are often called layer-3 switches or multilayer switches.
BRIDGE
BRIDGE: A network bridge is a network device that connects multiple network segments. In the OSI model bridging acts in the first two layers, below the network layer.
WIRELESS ACCESS POINT
WAP: is a device that allows wireless devices to connect to a wired network using Wi-Fi, or related standards. The AP usually connects to a router (via a wired network) as a standalone device, but it can also be an integral component of the router itself.
NETWORKING DEVICES (con't)
ROUTER
ROUTER: A wireless router is a device that performs the functions of a router but also includes the functions of a wireless access point. It is commonly used to provide access to the Internet or a computer network
WIRELESS ADAPTER FOR PC

WIRELESS CARD FOR LAPTOP
WIRELESS ADAPTER: A wireless network interface controller (WNIC) is a network interface controller which connects to a radio-based computer network rather than a wire-based network such as Token Ring or Ethernet
INTERNET SERVICE PROVIDER

is a business or organization that offers users access to the Internet and related services. Many but not all ISPs are telephone companies or other telecommunication providers. They provide services such as Internet access, Internet transit, domain name registration and hosting, dial-up access, leased line access and colocation. Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned.
