4U18N-B550

Whether or not a processor is built into the device.

The quantity of processors which can be used by the product.

The number of places where DIMMs can be connected. A DIMM or dual in-line memory module comprises a series of dynamic random-access memory integrated circuits. These modules are mounted on a printed circuit board and designed for use in personal computers, workstations and servers. DIMMs began to replace SIMMs (single in-line memory modules) as the predominant type of memory module as Intel P5-based Pentium processors began to gain market share.

Types of memory which can be used with the product.

The maximum internal memory which is available in the product.

Design of the memory e.g. 240-pin DIMM, SO-DIMM.

The voltage (V) of the memory in the device.

How many storage drives can be fit into the product at once.

Hot-swap hard drives are drives that can be removed and replaced during operation. Hot-swap hard drives are placed into hot-swap hard drive bays inside computers.

"Graphic adapter" is the hardware that produces images on a display. "On-board" means that the graphics adapter is intergrated inside the motherboard.

An Ethernet LAN (Local Area Network) interface is present, for a wired conection via a cable.

Number of Ethernet LAN (RJ-45) ports (connecting interfaces) in the device.  Ethernet LAN (RJ-45) ports allow a computer to connect to the ethernet.

Number of VGA (D-Sub) ports (connecting interfaces) in the device. The VGA (D-Sub) connector is a 15 pin connector between a computer and a monitor. It was first introduced in 1987 by IBM.

The BIOS (Basic Input/Output System) initializes and tests system hardware components, and loads a bootloader or an operating system from a mass memory device. The BIOS additionally provides abstraction layer for the hardware, i.e. a consistent way for application programs and operating systems to interact with the keyboard, display, and other input/output devices. There are several types of BIOS, including the  motherboard ROM BIOS, video BIOS, drive controller BIOS, network adapter BIOS, and SCSI adapter BIOS.

The type of rigid framework onto which is the hosuing for device components.

The button which is pressed to switch the device on or off.

The method used to cool the device or to cool the air around the device.

The quantity of fans (apparatus with rotating blades that creates a current of air for cooling or ventilation).

The way in which the product is powered e.g. rechargeable battery, mains electricity connected via a plug and cable.

The voltage of the AC electricity that is inputted into the product.

The minimum and maximum temperatures at which the product can be safely operated.

The minimum and maximum temperatures at which the product can be safely stored.

The measurement or extent of something from side to side.

The distance from the front to the back of something.

The measurement of the product from head to foot or from base to top.
