Computer motherboards are printed circuit boards (PCBs) that house basic computer circuitry and vital components. They are devices into which other boards or cards are plugged.
|
|
Computer power supplies convert alternating current (AC) line to direct current (DC) line, needed by the computer.
|
|
Computers are programmable electronic devices that accept data, execute prerecorded instructions, perform mathematical and logical operations, and output results.

Data storage systems are used to store, protect and manage computer data. Many types of disk drives and tape drives are available.
|
|
Desktop personal computers (PCs) are small, relatively inexpensive computers that are designed for individual users. Typically, these devices include a monitor, keyboard, mouse, and other peripherals.

Dynamic random access memory (DRAM) chips are single-transistor memory cells that use small capacitors to store each bit of memory in an addressable format that consists of rows and columns. Because capacitors are unable to hold a charge indefinitely, DRAM memory chips require a near-constant pulse of current to retain stored information.

Hard drives are integral, non-volatile, electronic data storage units inside computers. Traditionally, hard drives were hard-wired into computers. Removeable hard disks and drives are also available.

|
Industrial computer monitors are ruggedized for use in control room, factory floor, or process applications.

Memory chips are internal storage areas in computers. Although the term “memory chip” commonly refers to a computer's random access memory (RAM), this product area includes many different types of electronic data storage. Computer memory stores data electronically in cells. Without memory chips, a computer could not read programs or retain data.

Microprocessor chips (MPU) are silicon devices that serve as the central processing unit (CPU) in computers. They contain thousands of electronic components and use a collection of machine instructions to perform mathematical operations and move data from one memory location to another.

Network equipment is used to split, switch, boost, or direct packets of information along a network. This product area includes network hubs, switches, routers, bridges, gateways, multiplexers, transceivers and firewalls. Often, network equipment is defined by is protocol or port type (e.g., Ethernet switch, USB hub).
|
|
Network switches route packets between ports at the OSI layer 2, which means that (in Ethernet) the switches decide where incoming packets are transferred to, based on the NIC's 48-bit address.

|
Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.
