Final answer:
The statement is False. Both big and small companies can use either multitier or two-tier client/server architectures based on their specific needs.
Step-by-step explanation:
The statement that big companies use multitier client/server architectures and small companies use two-tiered client/server architectures is False. The choice between a multitier and two-tier client/server architecture depends on various factors, such as the size and complexity of the application, the number of users, and the scalability requirements.
Both big and small companies can use either multitier or two-tier architectures based on their specific needs. For example, big companies may opt for a two-tier architecture if their applications are simple and do not require a separate application server. On the other hand, small companies may choose a multitier architecture if their applications are complex and require scalability and load balancing.
Therefore, the choice of a client/server architecture is not solely determined by the size of a company, but rather by the specific requirements and constraints of the application.
