Networks can be defined as _____________________?
- Networks can be defined as :
- a collection of interconnected hosts
- generally via shared media which can be wired or wireless .
- this enables the hosts to share information
- a computer network can be as simple as two computers connected by a single wire.
- a collection of interconnected hosts
the internet is a network of ____________?

identify
There are two ways to identify a device on a network.
what are they?
- mac address
and
- IP address
define a MAC address ?
- MAC address:
- is a factory coded 48-bits hardware address
- used when devices are logically connected.
when are IP addresses used?
- IP address :
- is used when the devices are not logically conneted
true or false all devices are given a logical address.
true.
this logical address is called the Internet Protocol address .

Network Layer
Name layer 2 of the OSI model.
Data Link layer
What is layer 1 of the OSI model?
physical layer
Descibe the characteristics of the Application layer.
- application layer:
- This is where the user application sits
- it needs to transfer data between or among hosts
- example: file transfer application(FTP) , electronic mail
- this layer is also the only layer that the user interacts with.
- allows acess for the user to get varied network services

all connections between multiple devices in a network
what layer tracks dialoge between devices on a network ?
session layer
the transport layer is used to …..?
transfer data between applications
what layer is responsible for ened to end communication on a network?
the transport layer
