VGA

The term VGA (Video Graphics Array or Video Graphics Adapter) is a graphics display system for PCs developed by IBM. VGA has become one of the standards for the PC image. In text mode, VGA provides a resolution of 720 by 400 pixels. In graphics mode, the resolution is either 640 by 480 (with 16 colors) or 320 by 200 (with 256 colors). The color palette is 262,144.Unlike earlier graphic standards for PCs - MDA, CGA, EGA and VGA - uses analog signals rather than digital signals. Since its introduction in 1987, several other standards have been developed that offer greater resolution and more colors (SVGA, XGA ...), but VGA remains the denominator used. All personal computers manufactured today still have support VGA, and possibly some other more advanced connection.

MicroUSB

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

HDMI

HDMI (High-Definition Multimedia Interface) is a digital interface standard designed for the simultaneous transmission of uncompressed audio and video streams from a compatible source to a digital display or receiver.

This interface employs Transition-Minimized Differential Signaling (TMDS) to maintain data integrity at high frequencies. Throughout its revisions, HDMI has evolved from a basic digital video solution into a complex data bus capable of carrying 4K signals at 60Hz, dynamic metadata, and bidirectional control protocols between devices.

Version	Bandwidth	Audio/Video Support
1.0 - 1.2	4.9 Gbit/s	1080p @ 60Hz, 8 LPCM channels
1.3 - 1.4	10.2 Gbit/s	4K @ 30Hz, Deep Color, ARC, Ethernet
2.0	18.0 Gbit/s	4K @ 60Hz, 32 audio channels, HDR

The mass adoption of the HDMI standard has transformed the interconnect architecture in multimedia data centers and high-performance workstations. Its ability to integrate Audio Return Channels (ARC/eARC) and Ethernet connectivity (HEC) has drastically simplified structural cabling, eliminating the need for multiple redundant analog and digital cables while ensuring signal integrity over significant distances through active equalization.

CEC Control and Multi-Streaming Integration

A critical innovation in version 2.0 is the ability to deliver simultaneous dual video streams on the same screen and up to four independent audio streams, optimizing bandwidth for multi-user applications.

Key Advantages

Pure digital transmission avoiding D/A signal degradation.
Full backward compatibility across all standard versions.
Native support for high-resolution audio formats like Dolby TrueHD and DTS-HD.
Support for 21:9 cinema aspect ratios and dynamic lip-sync.

Note: Final interface performance is dependent on the cable certification (Standard, High Speed, or Premium High Speed).

Mini USB

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.

Types SATA connectors

Serial ATA or SATA (acronym for Serial Advanced Technology Attachment) is a data transfer interface between the motherboard and some storage devices such as hard disk, regrabadores readers and CD/DVD/BR, SSDs or other high performance devices are still being developed. SATA I Frequency: 1500 MHz Bits: 1. Bits 8 Real Speed: 150 MB/s. SATA II. Frequency: 3000 MHz Bits: 1 bits 8 Real Speed: 300 MB/s. SATA III Frequency: 6000 MHz Bits: 1.
