The USB (Universal Serial Bus) is a standard that defines the cables, connectors and used a bus to connect, communicate, computers, peripherals and electronic devices protocols Transmission Rates Low speed (USB 1.0). Transfer rate up to 1.5 Mbit/s (188 kB/s) used in keyboard, mouse ... transfer rate up to 12 Mbit/s (1.5 MB/s) High Speed ??(USB 2.0): Rate transferencia up to 480 Mbit/s (60 MB/s) SuperSpeed ??(USB 3.0) transfer rate up to 4.8 Gbit/s (600 MB/s) Connector Types 1 - USB type A (4 pin) 2. - USB type B (4 pin) 3 - Mini A (5-pin) 4 - Mini B (5-pin) 5 - Micro A (5-pin) 6 - Micro B (5-pin)
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
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.
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 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.
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
The term refers generally to control the amount of flash light emitted by the measuring light when returning to the same flash sensor through the lens. In TTL flash metering it occurs after the shutter has opened -the sensors record the amount of light created flash back to the camera through the lens and flash ( turns off automatically "cooling" ) when you haveproduced an adequate amount of light.
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.
Reversible USB Type-C
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 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.
It is a special multi point communication for industrial machinery by its format adapted to long distance and heavy machinery. The connector is used to connect the DB9 serial port or popularly called. One characteristic is that it is able to greatly reduce the noise so that the distance is much greater.
DC jack connector
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.
