The best Network design for a coffee shop according to a tight budget that Miss Becca is following would be decided by selecting a type of system, selecting a protocol and network switching device, type of cable used, type of communication device to use and the internet service to be used.
The first step would be to select the type of system. The type I would recommend is a file-server system as it is comparatively cheaper than client/server or terminal server. The data accessed by the users is stored on a single server and their own stations do not have any memory storage devices.
The second step would be selecting a protocol to be used. A protocol is a set of rules governing communication within and between computing endpoints. In our situation it would be best to use TCP/IP. Using TCP, applications on networked hosts can create connections to one another. The protocol guarantees reliable and in-order delivery of data from sender to receiver. TCP also distinguishes data for multiple connections by concurrent applications.
