1. 1. Summarize and describe the basic functions in the IEEE 802.11 Physical layer (PHY) and
Data Link Control layer (DLC).
Solution
Physical layer
1.It tells the electrical and physical details for a data connection.it tells the association among the
apparatus and a medium like copper and optic fibre ...etc.it contains the stratum of
voltage,impedance,pins...etc.and signal duration and same features and also the frequency for a
wireless utensils
2.Genarally the recognitions of this physical layer is used for tripping,inactivating and organising
the physical layer among the hosts. .
3.It is acccomplished to impart and get the unorganised raw data in a physical element.RJ45 is a
much general connector for this physical layer.
3.It mainly tells the tranmission node as uncompounded,half-duplex and full duplex. it teels the
network topology in the form of a mesh,ring or bus superlatively..It is a sheet of low-level
networking utensils like cables,hubs and repeaters...etc.
4.The main function of this physical layer is to tell exact bit model to use the exac protocol for
every kind of media to code the data into media gesture.
Data link layer
1.It is the next layer of physical layer in the OSI Model.it is a protocol layer which coveys the
data among the neighbouring nodes in case of wide area networks or between the similar nodes
in local area networks.
2.It offers the task and way of conveying data among the network creatures and used to offer the
procedure to code and reduce the exact errors that produce in the physical layer.
3.Data link protocols indicates how the equipments reduce and recuperate the collisions and also
offer tthe way to reduce them.
4.It is apprehended with local convayance of frames among the equipments on the similar Local
area network(LAN).
5.The data link layers functionality is accomdated with the4 link layer and squat layer of a OSI
Model.Tthe data link layer retorts to solocits from a layer called network and then affairs the
solicits to the physical layer.
