UNIT 9 P1-DESCRIBE THE TYPES OF NETWORKS AVAILABLE AND HOW THEY RELATE TO PARTICULAR NETWORK STANDARDS AND PROTOCOLS
LAN: LAN stands for Local Area Network. It connects network devices over a geographical distance. A LAN is usually found in somewhere like an office, school or somewhere like your own home. They are normally controlled and managed by a single person or organization. Some of the connectivity technologies involved is Ethernet and Token ring. LAN uses media such as UTP (Unshielded twisted pair), fibre or High Speed. Technologies involved in LAN include Ethernet, Fast-Ethernet and Giga-Ethernet.

WAN: WAN stands for Wide Area Network. It spans a large geographical area, the most common WAN Around is the internet, as it spans the

IEEE: IEEE Stands for The Institute Of Electrical and Electronics Engineers. It is an organization for people in the electrical engineers and electronic s field. IEEE’s mission statement is ‘to foster technological innovation and excellence for the benefit of humanity.’ It looks for people who are dedicated to creating standards. They are one of the leading standard organizations in the world. The most famous ones they are associated with are probably the IEEE 802 Family. The standards involved in these work with LAN’S and other connections.

ISO: The international organization for standardization is the world’s largest developer of standards. For networks, ISO is most famous for O3SI. (Open systems interconnection). OSI was published in 1984. The OSI has 7 different layers. OSI was supposed to serve as a suite of protocols to be used on the internet. However this is not the case as the TCP/IP Protocol suite was selected instead. So instead the OSI was used on telecommunication

If the walls are thick (E.G made of concrete) then there will be less penetration from the signal trying to get into a different room.
DISTANCE BETWEEN DEVICES: The distance between devices also affects speed. If the router is in a living room in a home and you are in a room that is quite far away, the connection will be slower than someone who is in the living room.
PHYSICAL OBSTRUCTIONS: The More Obstructions In the way of the transmitter/receiver the more it affects the network.

UNIT 9 M1: Compare the benefits and disadvantages of peer-to-peer network

Peer-to-Peer Network: A peer-to-peer network is a network made up of personal computers. These personal computers act as both a client and a server, so this means that each personal computer can exchange files and emails to every other computer on the network. Another thing about peer-to-peer networks is that each computer has access to all the files on any other computer on the network. This is unless one of the computer users restricts files on their computer.
ADVANTAGES:
-Easy and simple to level up
-Access any file as long as it is a shared folder
-Cheaper than client server networks
-If one computer fails all of the others still
