Computer supplies businesses sell the equipment, accessories and consumables used with desktop computers and laptops. Products commonly include keyboards, mice, monitors, cables, adapters, webcams, headsets, speakers, docking stations and external storage. Some retailers also stock internal components such as memory, drives, power supplies and graphics cards, as well as routers and other basic networking equipment. Customers may also find printer supplies, including ink and toner cartridges, paper and replacement parts, alongside items such as laptop bags, screen cleaners and surge-protected power leads. Stock can range from everyday accessories to parts for building or upgrading a computer, and compatibility may vary by device and model. Businesses in this category may offer product advice, help identify suitable replacements, or arrange delivery; some also provide basic installation or setup, although repair work is not a standard service offered by every supplier.
