Riistvara

Riistvara is the Estonian term for hardware, referring to the physical parts of computer systems and other equipment. In information technology, it contrasts with software, which consists of the programs and data that run on the hardware.

Hardware includes central components such as the central processing unit (CPU), memory (RAM), non-volatile storage (SSD or HDD), and a motherboard, as well as peripheral devices like keyboards, mice, monitors, printers, and networking adapters. It also covers power supplies, cooling systems, and the case or chassis. In specialized contexts, hardware also means mechanical devices or instrumentation.

Design and manufacture involve electrical engineering, circuit design, PCB layout, firmware development, and system integration. After prototyping, components are tested for performance and reliability, then mass-produced and certified for safety and compatibility (for example, interfaces and standards such as USB, PCIe, SATA, HDMI, Wi-Fi).

Lifecycle considerations include component obsolescence, repairability, and end-of-life recycling. The term riistvara is used across the Estonian tech sector to discuss hardware research, procurement, and maintenance, including consumer electronics and industrial equipment.
