Servidor NAS QNAP 2bay 4Gb (TS-253D-4G)

The sizes of storage drives that can be used with the product.

The device uses RAID, which is a storage technology that combines multiple disk drive components into a logical unit for the purposes of data redundancy and performance improvement. Data is distributed across the drives in one of several ways, referred to as RAID levels, depending on the specific level of redundancy and performance required.

The places where drives (hot-swap drives) can be inserted to or removed from the computer.

Storage drives are built into the system.

Type of storage drives built into the device e.g. HDD (hard disk drive), SSD (solid-state drive).

The type of storage drives the device is compatible with.

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

The manufacturer that produced the processor.

A family of processors is a group of processors produced by one company over a short period of time e.g. Intel Pentium processors.

The model number for the processor in a computer.

The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.

The turbo boost is an automatic, managed accelleration of the processor when one of the cores is overloaded.

The number of central processing units ('cores') in a processor. Some processors have 1 core, others have 2 (e.g. Intel Core Duo) or more (e.g. the Intel Xeon E7-2850 has 10 cores).

The process which is performed by the processor e.g. CPU (Central Processing Unit).

Operating modes for the processors that place restrictions on the type and scope of operations for certain processes run by the CPU. This design allows the operating system to run with more privileges than application software.

Mechanical component(s) that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the processor to be replaced without soldering.

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

The type of internal memory such as RAM, GDDR5.

Number and type of memory expansion slots; including connector and memory module descriptions

A computer's memory which is directly accessible to the CPU.

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

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

The different speed levels of the Ethernet LAN connection.

Whether the product features a DHCP (Dynamic Host Configuration Protocol) to obtain IP addresses within a network.

A server is a system which that responds to requests across a computer network to provide, or help to provide, a network service. DCHP servers uses the DCHP (Dynamic Host Configuration Protocol), which is a standardized networking protocol used by servers on an IP network to allocate IP addresses to computers. The purpose of DHCP is to automate the IP address configuration of a computer without a network administrator. IP addresses are typically selected from a range of assigned IP addresses stored in a database on the server and issued to a computer which requests a new IP address. An IP address is assigned to a computer for a set interval, after which, the computer must renew the IP address or acquire a new one.

Network protocols tested as compatible with this product e.g. FTP,HTML, POP.

The device features a socket into which a USB cable can be plugged.

USB 2.0 ports have a data transmission speed of 480 Mbps, and are backwards compatible with USB 1.1 ports. You can connect all kinds of peripheral devices to them.

The number of sockets (ports) for HDMI connections. HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device ("the source device") to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for existing analog video standards.

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.

The feature may not be available on all computing systems. Functionality, performance, and other benefits of this feature may vary depending on system configuration.

List of types of chassis available and their expandability if applicable.

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

El color ej. rojo, azul, verde, negro, blanco.

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