LAN
(LOCAL AREA NETWORK)
Network that covers only a limited geographical
area.
ex: classroom, computer laboratory, office or
group of buildings
Consists of a server and several computers
Server is the one that manages the resources in a
network and provides central storage for data
and programs

HOW DOES INTERNET WORK?
Packet–is a data that has been broken into small
piece of data
ex: email message, file, graphic
contain the small piece of data together with
the recipient or destination, sender or
origin and sequence of information to
reassemble the data at the destination
when travels the network, it finds the fastest
path available to arrive at the destination
through a device called router

through a device called router
Router–is a hardware device that allows you to
connect several computers and other devices to a
single Internet connection
serves as a traffic cop for network signals
router send the packets along alternate paths

Packet switching –a technique for breaking the
data into packets, sending it through the best path
using the router and reassembling the data when
it arrives at its destination
network should follow a protocol or standard
called TCP/IPorTransmission Control
Protocol.
