Final answer:
For a small company with a tight budget and four workers, a Peer-to-Peer (P2P) network is the most suitable because it is cost-effective, easy to set up, and allows all computers to share resources directly without a central server.
Step-by-step explanation:
For a small company with a tight budget and four workers, a suitable type of network is a Peer-to-Peer (P2P) network. In this network model, all computers have equal status and can communicate directly with each other without the need for a central server. This decentralized approach makes it cost-effective and straightforward to implement and manage.
A P2P network allows these four workers to share resources such as files and printers directly among themselves. Setup is usually simple because it can often be facilitated using the existing operating systems' networking capabilities without the need for additional expensive hardware or software. This network type is ideal for small, collaborative teams that do not require the complexities of a client-server network.
