For offices in other cities, they will use WAN(Wide area network) which is used for communication worldwide. The standard protocols and technologies used are TCPIP for the wired transmission and UDP for wireless transmission. RE: Response Sai Chandra Reddy Kotha 11/6/2016 10:11:45 PM When in UDP preferred over TCP In situations where you really want to get a simple answer to another server quickly, UDP works best. In general, you want the answer to be in one response packet, and you are prepared to implement your own protocol for reliability or to resend. DNS is the perfect description of this use case. The costs of connection setups are way too high (yet, DNS does support a TCP mode as well). Another case is when you are delivering data that can be lost because newer data coming in will replace that previous data/state. Weather data, video streaming, a stock quotation service (not used for actual trading), or gaming data comes to mind. Another case is when you are managing a tremendous amount of state and you want to avoid using TCP because the OS cannot handle that many sessions. This is a rare case today. In fact, there are now userland TCP stacks that can be used so that the application writer may have finer grained control over the resources needed for that TCP state. Prior to 2003, UDP was really the only game in town. One other case is for multicast traffic. UDP can be multicasted to multiple hosts whereas TCP cannot do this at all.

Boston, New York, Washington D.C. and Philadelphia are hundreds of feet apart so the agency would have to use a wide area network(WAN) because of this distance. The routers would be located in each city that Atlas Advertising would be located in along with WLANS. 2. They are using the internet model protocol, De Jure standards along with naive apps and byod to help the company save money and cut down on security. Protocols and Topologies Nishithkumar Ileshkumar Patel 11/19/2016 3:42:36 PM Protocols: Transmission Control Protocol (TCP), which uses a set of rules to exchange messages with other Internet points at the information packet level Internet Protocol (IP), which uses a set of rules to send and receive messages at the Internet address level Additional protocols that include the Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP), each with defined sets of rules to use with corresponding programs elsewhere on the Internet There are many other Internet protocols, such as the Border Gateway Protocol (BGP) and the Dynamic Host Configuration Protocol (DHCP).
