NETWORKING BASICS

What is the Network ? Network history ? Network types ( LAN , MAN , WAN ) . Host types (client , server) . Server types . Full duplex and Half duplex .

What is the Network ? Two or more connected computers that can share Resources such as : Data Printer Application

Network history ? Mainframe

Network types ( LAN , MAN , WAN ) Three main networking technologies are used to connect computers and networks together: Local area network (LAN) Metropolitan area network (MAN) Wide area network (WAN)

LAN Used to network computers located in a limited geographical area such as a room, floor, or building .

EXAMPLE OF A LAN

MAN A MAN is used to interconnect networks that are larger than a LAN but smaller than a WAN.

EXAMPLE OF A MAN

WAN Spans a large geographic area Defined as an internetwork that connects many LANs Examples of WANs The Internet

EXAMPLE OF A WAN

Host types (Client , Server) Client /Client networks Client / Server networks

Server types File Server Print Server Web Server Application Server Proxy Server Mail Server Remote access Server Database Server
