What is the full form of VGA?

VGA stands for "Video Graphics Array"

VGA represents Video Graphics Array. It is showcase equipment created by IBM in 1987. It was first presented with an IBM PS/2 line of PCs. It gives a goal of 640x480 pixels and an invigorating pace of 60 Hz.

VGA has been alluded to as a cluster rather than an adopter since it was executed from the beginning as a solitary chip (ASIC). It utilizes simple signals as opposed to advanced signs.

Specialized Specifications

The first VGA has the accompanying determination:

• 256 kB Video RAM
• 16-shading and 256-shading paletted show modes.
• 262,144-shading worldwide palette (6 pieces, and hence 64 potential levels, for every one of the red, green, and blue channels using the RAMDAC)
• Selectable 25.175 MHz or 28.322 MHz ace pixel clock
• Normal line rate fixed at 31.469 kHz
• Limit of 800 even pixels
• Limit of 600 lines
• Invigorate rates at up to 70 Hz
• Vertical clear hinder
• Planar mode: up to 16 tones (4-bit planes)
• Stuffed pixel mode: 256 tones (Mode 13h)
• Equipment smooth looking over help
• No equipment sprites,
• No Blitter yet underpins extremely quick information moves through "VGA hook" registers.
• Barrel shifter
• Split-screen uphold
• 0.7 V top to-top
• 75 ohm twofold ended impedance (18.7 mA, 13 mW)

Shape and Size:

A VGA connector is formed like a trapezoid and it has 15 pins. If you have an old screen intended for the more established principles will be unable to work with Video Graphics Array norms.

The more established VGAs give a goal of 640x480 pixels. After that form, numerous amendments have been presented. The most widely recognized adaptation of VGA is Super VGA (SVGA). It takes into account goals more noteworthy than 640x480, for example, 800x600 or 1024x768.
