When we talk about RJ45 ("Registered Jack" 45) we refer to a telecommunications network interface for wired connection of voice and data equipment.

This connector has 8 pins or connections and may have a specific category depending on the data transfer speed and bandwidth (category 5e, 6, etc.)

The common application is their use in Ethernet network cables under TIA/EIA-568-B standard that defines the arrangement of pins (pinout), but can also be used for other applications.

In IEC connector or cable with a base (usually plastic) and a plug to connect to the socket (plug), if we put these two things we would get the named SCHUKO is the overall connector. The schuko not determine the type of connector. It would be determined by the specification of the International Electrotechnical Commision (IEC). We leave a small sample of Schukos internationally.

The RS232 connector is a connector type 9-pin connector is popularly called Series. It is a connector that was once widely used by various components of the PC, such as a mouse, keyboard ... but over time it has fallen into disuse and replaced by the USB connector trying to emulate the latest version number. It is currently used by robots, elevators, POS and industrial machinery.

USB-C reversible USB version called USB cables USB Type C Type C or USB reversible. The important thing is this type of USB is that it has top and bottom. So you may save the blows that are given involuntarily to connect the connector upside down. It is also characterized in that when connected will make an audible "click". The USB-C or reversible USB cables can reach 10 Gbps and support USB 3.0, 3.1Use is estimated up to 10,000 applications and has some measures 8.4mm x 2.6mm is also compatible with USB 3.1 and USB indicate creators

The Simple Network Management Protocol, or SNMP (English Simple Network Management Protocol) is a protocol for the application layer that facilitates the exchange of management information between network devices. It allows administrators to monitor network performance, find and solve problems, and plan for growth. In an attempt to explain in a simple way, we could imagine that instala card using SNMP to monitor a UPS on a network.

IEC connector is the common name for a set of thirteen power connectors (called the connector specifications) and thirteen outlet panels (called input) specification defined by IEC 60320 (formerly IEC 320) of the International Electrotechnical Commission ( IEC). When used without other qualifiers, "IEC connector" usually refers specifically to the C13 and C14 connectors.

USB 3.0 is the second major revision of the standard Universal Serial Bus (USB) connectivity for computing. USB 3.0 has transmission speeds of up to 5 Gbit/s, which is 10 times faster than USB 2.0 (480 Mbit/s). Connector Types 1 - USB type A plug 2 - 3 USB type A female - USB type B 4 - Micro USB B

An uninterruptible power supply, UPS, also known as UPS (uninterruptible power supply English), is a device that, thanks to batteries or other energy storage elements, can provide power for a limited time and for a blackout all the devices connected. Other features that can be added to these teams is to improve the power qualityéctrica reaching loads, ups and downs filtering and eliminating voltage harmonics of the network in the case of using AC. There are different types of UPS UPS DC loads connected to the UPS require DC power, so they will transform the alternating current to direct current sales network and use it to power the load and store it in your batterys. So they do not require converters between the batteries and loads. UPS AC UPS obtained These outputs an AC signal, so they need an inverter to convert the direct signal from the batteries in an alternating signal. UPS standby (Standby Power Systems) This system has two main circuits: the power line, which only addsa stabilized and additional filtering of each team to normal feed, and the actual circuit UPS circuit whose core is called "inverter". It is called system "standby" or waiting, because the circuit of alternative power, the inverter is "offline" or inactive, waiting to become operational when it produces a failure in the power supply. It has a switching element that connectsand either circuit switched alternately. UPS line-interactive (in-line) This type of UPS regulates voltage variations by elevations or reductions in mains voltage. During these interventions, the UPS uses its battery to perform the voltage regulation. UPS online (online) In contrast, the UPS "online" (on-line), the battery and the inverter are permanently It is utiized, ensuring a maximum response in a timely manner before the event of network failure. In addition, they can also correct the frequency shifts as re-generate the ac wave permanently. Diagram UPS online In the picture (1) Rectifier The picture (2): battery in the picture (3): Inverter

RS-232 (Recommended Standard 232, also known as EIA/TIA RS-232C) is an interface that designates a standard for the exchange of a series of binary data between a DTE (Data Terminal Equipment) and DCE (Data Communication Equipment , Data Communication Equipment), although there are others in which the RS-232 interface is also used. An equivalent definition published by the ITU is called V.24. The RS-232 is a connectorDB-25 type (25-pin), although it is normal to find the version of 9-pin (DE-9, or popularly also called DB-9), cheaper and even extended to certain types of peripherals (such as serial mouse PC).

The mini USB connectors are smaller than their standard counterparts and have USB fifth pin. The fifth pin is known as the pin ID and is typically not used in mini USB connectors. It was designed to allow later improved USB technology. The mini USB connectors have a cycle life of at least 5000 connections and disconnections, which accommodates the mobile nature of the devices that are designed to interact. The standard USB connectors are generally used with devices that are stationary and not disconnected often.

or horizontal. The micro USB with five pins, which pins identification (ID) Micro AB USB connectors special work. AB connectors with pin ID can allow the device to function as a connector A or B to standard USB technology. This gives the new smart phones and other devices the option to act as either a single storage device or as provi
