Network Services

Resource sharing allows network users to share physical (e.g., printer or CPU) and logical (e.g., data files or software) resources

Client-server model supports some network nodes as services (servers) and other nodes as users (clients) of those services. Client programs typically run on user's computer, sending requests to server programs on remote computer. This minimizes costs, replication, etc.
