Difference between push protocol and pull protocol?
> "Pull" protocols are those that put some data out there to be accessible
> via a URL. The data does not change based on who requests the
> information. Yadis is such a protocol, since when an Relying Party goes
> to fetch the data, there is no specified way to change the data based on
> who is requesting it.
>
> "Push" protocols are those that allow the user to modify the data based

> transmitted by redirecting the user between the Relying Party and the
> Identity Provider, and the user can choose to have the Identity Provider
> send his or her authentication information or to cancel the transaction.
Does Packet Collisions occur in Token Ring Networks?
No, unless the ring is broken then collision can occur
Is the wep key the routOrs password?
No
The WEP key is the key used to encrypt the wireless traffic, so people can't sniff the data and see what your doing. No WEP key, no connect to the network. No router password, and you can't log into the router to modify the WEP key.

What are static and dynamic addressing?
If a network uses static addressing, it means that each network interface has an assigned IP address that it uses all of the time or whenever it is online. If a network uses dynamic addressing, it means that when a network interface asks to join the network, it is randomly allocated an IP address from a pool of available addresses within that network. Thus, under dynamic addressing, a computer may possess over time (e.g. across reboots) a variety of different IP addresses, but under static addressing the computer has a well-defined IP address which it uses always and which no other computer ever uses. Dynamic addressing is most useful in applications such as dial-up networks, VPNs, and similar scenarios where end-user machines are intermittently connected to the network.
The Application layer uses protocols that are implemented within applications and services. While applications provide people with a way to create messages and Application layer services establish an interface to the network, protocols provide the rules and formats that govern how data is treated.
What is application layer message?
data which an application wants to send and passed onto the transport layer

Discuss the role of network within the organizations and the resource implications of networks?
Role of the networks within different organizations
Nowadays networks become major data transmission in the world. Networks typically involve collaboration. For invention and innovation, networks have become the means to collaboration, helping diffuse knowledge, reproduce creativity, and pull together the resources needed to undertake research. Networks have become easier than ever to establish and join. The Internet, the Web and telecommunications have allowed the creation of networks for most every social and economic activity in existence today. Helping this dynamic is the rapid decline in the cost of networking during the past four decades, which helped provide easier access on a global scale. So the network system is very important for the different types of organizations. The role of the network within the organizations is as follows.
· The network helps them to increase their employees' productivity
In the network environment when the employees are working they can quickly share their ideas because nowadays the organizations are more competitive.
· It helps to reduce office equipments costs
In the network system all the equipments in the organization are using by multiple users. So, an equipment uses by multiple employees at a time, so no need to spend lots of money to buy equipments for all the departments in the organization.
· It helps to access to Resources anytime or anywhere
With remote access in place, one can travel or work remotely and still be connected. Access to files, data, and messages when away from the office provides employee flexibility. Users can respond to co-workers and customers quickly, from anywhere.
· It helps to increase Storage Capacity
As there is more than one computer on a network which can easily share files, the issue of storage capacity gets resolved to a great amount. An individual computer might fall due to the less storage memory, but when many computers are on a network, memory of different computers can be used in such case. One can also design a storage server on the network in order to have a huge storage capacity.
· It helps to reduce Communication Costs
In the network environment the network-based communication such as e-mail and instant messenger services are cost-effective alternatives to phoning and faxing, with the potential to deliver significant savings in long distance charges. The combination of the public Internet with secure VPN technology allows for office-to-office networking without costly dedicated Wide Area Network (WAN) connections, also realizing major cost savings.
· It helps to manage the software and resources centrally
· It helps to allow network versions of software for their speedy installation on workstations from the file server
· It helps to share software amongst different user
· And also the data is most valuable thing to the organizations. So in the network environment, all the data of the branches of the organization are managing centrally with high security such as authentication and providing password to the data and so on. So, these are giving much security to their data.
· It helps them to connect and sharing all the computers in the organization
