They are more expensive and are slower than Ethernet.
Nortel Networks doesn't have a CEO currently but rather a President of Business Services, Chris Ricaurte, and Chief Strategy Officer, George Riedel.
In most, but not all networks, rather than transmitting data in small pieces such a single character at a time, data will be sent in a larger piece referred to as a packet. The size of the packet is a tradeoff between network sharing, speed and error detection and recovery. Standard Ethernet uses a packet size of about 1500 bytes, while Wi-Fi defaults to a bit more than 2300 bytes.
you will have to switch networks, you will be on the nextel side rather than sprint, whose networks are not compatibal with each other
if you don't know it, don't do it , you will hurt rather than helping.
it is more expensive
its renewable
There is no purpose. It is rather unfortunate downside. In early years of networking networks were not capable of full duplex as result admins had to deal with collision domains. Problem of collision domains does not exist in modern equipment because data sent and received on different pairs of wires. There are exceptions but they are not applicable to the most of situations admins have to deal with.
All routers use a phone line (RJ11) as an input
That is false. Domain models are server-based networks while workgroups are peer-to-peer networks.
LAN Disadvantages: • Special security measures are needed to stop users from using programs and data that they should not have access to. (user login/password protection) • Networks are difficult to set up and need to be maintained by skilled technicians. • If the file server develops a serious fault, all the users are affected, rather than just one user in the case of a stand-alone machine. - Decisions on resource planning tend to become centralized. - Networks that have grown with little thought can be inefficient in the long term. -As traffic increases on a network the performance degrades unless it is designed properly. - The larger the network, the more difficult it is to manage.
congress is more representation rather than self governing
Places in a passive rather than an active role, which hinders learning.
