While cabling and servers form the foundations of a network, client systems provide users with an environment from which to access its facilities. This will usually be Microsoft Windows, although alternative operating systems like Linux, Apple MacOS, and RISC OS have specific strengths that may make them more suitable in certain applications, and all can co-exist on the same network.

The choice of physical hardware designs also continues to grow, with desktop PCs of all sizes now joined by notebook, palmtop, and tablet devices. Again, each solution has its own advantages and disadvantages, so advice from an experienced supplier like Atomwide can be invaluable. Recognising that excellent build quality and reliability are paramount when systems are in constant use, Atomwide helps customers to choose appropriate models from its preferred PC supplier, Compaq.

	"Sutton LEA has chosen Compaq as the standard for client PCs as we have been impressed by the range, resilience and pricing of the equipment. The smaller footprint Evo is ideal for use in small classrooms doubling as ICT suites." London Borough of Sutton
