• Networking - is the practice of linking two or more computing devices together for SHARING DATA
• Network - is a simply a group of two or more personal computers linked together.
• Most common type of network ?

  • Local - area network
  • Wide - area networks
• Networks are classified of three properties ?

  • Topology
  • Protocol
  • Architecture
• Topology - specifies geometric arrangement of the network.
• Common topologies are:

  • Bus
  • Ring
  • Star
• Protocol - specifies a common set of rules and signals the computer the network use to communicate
• Architecture - refers one of two major types of network architecture:

  • Per - to - peer - there is no server , and computer simply connect to other workgroup to share files , printers , and internet access
  • Client / server - there are ussually an NT domain controller. Can provide various services like roited internet access, e-mail, file sharing, and printer, and security across network
• Local area network - in other word , small network constrained to a small geographic area. Example of it is computer network within building
• Personal area network - a computer used for communication among computer devices, including smartphone and tablet. The reach of it is just few meters. PAN can be uses for communication
• Campus area network - a computer made up of an interconnection of local area networks ( LAN ) within limited geographical area.
• Metropolin area network - is a hybrid between a LAN and a WAN. WAN can connect two different buildings or officess in the same city or municipality.
• Wide area network - is a computer network that covers a broad area. They can also be connected through leased lines or satellites. The largest WAN existence is the internet
• Storage area network - is a dedicated storage network that provides access to consiolidate, block level storage. Typically has its own network of storage devices that not accessible through regular network by regular devices.
• Internet - is a global system of interconnected computer networks that use a standard of internet protocol suite to serve billion od users worldwide. It is also be defined a worldwide interconnection of computers of computer network that facilataed of sharing of information.

  • It owns Worldwideweb ( WWW )
• Virtual private network - is a private network that is contructed within a public network insfructure such us the global internet.
• Peer - to - peer network - is created when two or more PCs are connected and share resources without going through a separate server computer.
• Client - server network - is a computer network in which one centralized, powerful computer ( called the server ) is hib to which many less powerful personal computers or workstations ( called clients ) are connected.
• Network protocol - are set of rules, conventions, and data structures that dictate how devices exchange data across networks.
• Architecture - refers one of two major types of network architecture:
