Wireless networks are not laid out using the same topologies as wired networks. They have their own, different layouts. Smaller wireless networks, in which a small number of nodes closely positioned need to exchange data, can be arranged in an ad hoc fashion.
Geographically Distributed DATABASE spans on Different Computers, Multiple Networks and in different geographical locations.
Specialized Device for exchanging data amongst class based Networks & Subnetted (multiple parts of one network) is Router.

Good compromise over the other two topologies as it allows relatively high rate of data tansmittion. Well suited for temporary networks that must be set up in a hurry. Easy to implement and extend.
Network topologies is the means in which a network is structured. There are two types being physical and logical. Logical topology shows how data is delivered between a network.
An internetwork is a collection of individual networks, such as LANs or WANs, connected by routers to enable communication across different networks. It allows devices on different networks to exchange data by forwarding packets between them. The internet is a prime example of a vast internetwork connecting millions of networks worldwide.
Dedicated networks for voice, video and computer data communications required a different type of device in order to access the network. Telephones, televisions, and computers used specific technologies and different dedicated network structures, to communicate. Converged networks are capable of delivering voice, video and data services over the same communication channel or network structure.
The most reputable celluar data network is highly debatable as different companies offer services to suit the needs different people. Some very good networks providers are: AT&T, Verizon, Orange, Tmobile, O2, Virgin.
A distributed database spreads data across multiple drives. A redundant array of independent disks (RAID) is a very different way to spread data across multiple drives.
What are two characteristics of clients in data networks?Initiate data exchanges. May upload data to servers
When the application layer passes large amounts of data to the transport layer. The transport layer multiplex different applications' communication by dividing the application data into segments and placing a header on each segment to indicate which communication it is associated. Also, because networks can provide multiple routes that can have different transmission times, data can arrive in the wrong order. However by numbering and sequencing the segments, the transport layer can ensure that these segments are reassembled into proper order. Without segmentation, only one application would be able to receive data.
