Inside the different types of connectors for power supply we find one of the most common, the DC jack. Used in most connections in electronic devices such as routers, laptops, printers etc ... is the most used due to its easy assembly and connection. These connectors are mostly used in DC power supplies and installations.
The connector is cylindricalAnd we find its version in male and female format (A). The male connector is composed of the outer and inner metal part, where in each of them the energy travels, normally the inner part is used for the positive pole and the outside for the negative, but may vary according to manufacturer.
This type of connector is found in many diameters, the most common are 3.5mm and 5.5mm. Although we can andThere are several measures in terms of length and outer or inner diameter.
Its installation is simple, we can find several types of connectors, pair to weld or to screw with terminal block, it will depend on the user to choose the most suitable in its installation.
When purchasing the male connector to perform a repair we must know its diameter, length of the connector and internal diameter. If we proceed with aTo new installation only we must make sure that the male and female connector are of the same characteristics.

The Wifi technology is a wireless communication mechanism between devices. This technology allows you to connect devices such as computers, laptops, mobile etc... to the Internet or communicate with the devices themselves.

Applications can be several, among the most common are the access points, ideal for giving and sharing a connection signal to multiple devices. It is the typical configuration of a home user.
Repeater, ideal to repeat and amplify weak signal.

The power and range between devices basically depends on the antenna and its hardware.

The wireless signals work under a unified standard regulations, the standard that is based on the IEEE 802.11. These include IEEE 802.11b, IEEE 802.11g and IEEE 802.11n working at 11 Mbit/s, 54 Mbit/s and 300 Mbit/s, respectively.
Being any device with a standardized protocol such technology can connect to another using the same technology, making it a kind of universal connection.

The wireless networks are characterized by the ease and convenience of making connections in infrastructure, since it is not necessary to perform network cable installations.
it also allows connecting a lot of devices to a single node.

A DIN Rail is a metal rail of with standard size of 35 mm wide. (A)

It's commonly used on installation and assembly of electrical devices or controllers for home or business use.
Besides the typical DIN rail 35 mm x 7.5 mm, can also be found in other measures as:

- Mini DIN Rail, size 15 mm x 5.5 mm (B)
- DIN Rail, size 35 mm x 15 mm (C)
- G section, size 32 mm x 15 mm x 8mm (D)

These rails are designed for installations with a method of simple, fast and configurable fixing. Ideal for installation in electrical distribution points, distribution of telephone wiring, alarms, digital electric programmers, keystone adapter, attenuators and any other compatible device.

VDC would be the abbreviation for Volt Direct Current which translated would volts direct current. The idea of ??this type is unidirectional current to the load. Direct current is normally produced by batteries, thermocouples, solar cells and a dynamo electric machine type. The direct current can flow in conductors such as wires, but may also flow through semiconductors, insulators ... In the image: 1 - current per pulse 2 - Direct Current (DC) 3 - Alternating Current (AC) 4 - Variable Current

4G is the next generation of technology that the International Telecommunication Union has created for transferring data via the Internet. The speed is 100 MB/s downstream and 50 MB/s upstream, with a bandwidth of 20 MHz. The idea that used to wield the great value of 4G format that society is consuming more video and heavy images and this will make the mobile phone supports it. A continuación show you a small graphic comparison between 3G and 4G in the most common uses computer-related.

The DIN is a standard that was developed by the "Deutsches Institut für Normung" (one might call the national standards organization in Germany). The DIN is facing many sectors, but we have tried to focus on the DIN-oriented electronics and computing. In the case of Enclosures means qualifying under the German legislation on racks and is standardized to DIN 41494-7.

WAN, which is also known as wide area network is a network that consists of several private computers or organizations. Today with the speed that is in LANs is no longer necessary to use WAN

MiFi is a mobile router that acts as an access point to the Internet via 3G or later. You can connect to one or more devices at once by WiFi. It can be used with multiple WiFi devices such as desktops, laptops, tablets, smartphones, etc.

General Packet Radio Service (GPRS) or general packet radio service created in the 80s is an extension of the Global System for Mobile Communications (Global System for Mobile Communications or GSM) for the transmission of data by packet switching. A similar service for mobile phones, the IS-136 system. It allows transfer rates of 56-114 kbps. These Class A devicesThey can simultaneously use GPRS and GSM services. Only Class B may be connected to one of the two services at all times. While GSM service (voice or SMS) is used, the GPRS service, which automatically restarts when the GSM service ends is suspended. Most mobile phones are of this type. Class C are alternately connected to one or another service. Switching between GSM and GPRS shouldperformed manually.

(DHCP stands for Dynamic Host Configuration Protocol, in Spanish "protocol Dynamic Host Configuration") is a network protocol that allows clients to obtain an IP network configuration parameters automatically. It is a protocol for client/server where a server usually has a list of dynamic IP addresses and will allocate these customers as they are left freeKnowing at all times who has been in possession of that IP, how long it has had and who has been assigned later.

The global system for mobile communications (English Global System for Mobile communications, GSM, and originally from the French groupe spécial mobile) is a standard system, royalty-free, digital mobile phone. A GSM client can connect through your phone to your computer and send and receive emails, faxes, surf the Internet, access to the computer network security acompany (LAN/Intranet) and use other functions of digital data, including short message service (SMS) or text messages. What are the differences between GSM and UMTS? The GSM system operates by TDMA, ie, time is divided into slots and each user is assigned a slot, ie, a period for which data can be transmitted. Therefore each channel is shared by a ndetermined number of users. The system is a UMTS (WCDMA) code division multiple access broadband. In this system there are no time slots and GPRS. All users transmit simultaneously on the channel, but each user signals are encoded with a unique code so that even though we think that an "indecipherable signal" is formed by using the same frequencies simultaneously, It is not toyes, because the base station is capable of decoding and re perfectly separate each of the communications received from different users. This obviously implies a much higher channel utilization, to not share in time.
