HPE JD994A#ABB Network Switch Networking

1905-48

What switch device has, managed or unmanaged.

The number of basic switching RJ-45 Ethernet ports (sockets).

The way in which the network is working, e.g. IEEE 802.11a, IEEE 802.11b, IEEE 802.11g.

The product can use Oracle 10G, which is a database management system introduced in 2003.

A full-duplex system allows communication in both directions, and unlike half-duplex, allows this to happen simultaneously.

A Medium Dependent Interface (MDI) describes the interface (both physical and electrical) in a computer network from a physical layer implementation to the physical medium used to carry the transmission. Ethernet over twisted pair also defines a medium dependent interface crossover (MDIX) interface. Auto-MDIX ports on newer network interfaces detect if the connection would require a crossover, and automatically chooses the MDI or MDIX configuration to properly match the other end of the link.

The different speed levels of the Ethernet LAN connection.

A Virtual Local Area Network (VLAN) consists of a group of computers and switches that can be physically distributed over different networks and buildings, but form one LAN on a logical level.

Rates at which data can be transferred. May vary according to network configurations.

The data transfer capacity of the switch per second.

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

The type of mounting that can position devices in a shelving system (rack).

Devices can be placed on top of each other.

The colour e.g. red, blue, green, black, white.

List of regulatory safety standards for all countries in which this product has been certified.

List of countries and their respective regulatory agency standards with which the product complies.

Whether or not a processor is built into the device.

The model number for the processor in a computer.

The clock rate is the fundamental rate in cycles per second (measured in hertz) at which a computer performs its most basic operations such as adding two numbers. There are more factors, like internal memory size, that influence a computer's actual response time.

Type of memory in the device e.g. DDR3, SRAM (Static RAM).

The amount of memory, usually measured in bytes (e.g. MB, GB), which is installed in the system's hardware.

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

The device supports Power over Ethernet (PoE), which is one of several standardized or ad-hoc systems which pass electrical power along with data on Ethernet cabling. This allows a single cable to provide both data connection and electrical power to devices such as wireless access points or IP cameras.

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

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.

Weight of the product without packaging (net weight). If possible, the net weight is given including standard accessories and supplies. Please note that sometimes the manufacturer leaves out the weight of accessories and/or supplies.

Latency is the time needed to forward a packet of data.

The technology that enables connectivity of the device, e.g. wired or wireless.

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