A diskless client has no disk and depends on a server for all its software and storage needs. A diskless client remotely mounts its root (/), /usr, and /home file systems from a server.
A diskless client generates significant network traffic due to its continual need to procure OS software and virtual memory space from across the network. A diskless client cannot operate if it is detached from the network or if its server malfunctions.
