BIOS POST card for ISA bus BIOS POST card for PCI bus Professional BIOS POST card for PCI bus Two POST seven-segment displays integrated on a computer motherboard. The original IBM BIOS made POST diagnostic information available by outputting a number to I/O port 0x80 (a screen display was not possible with some failure modes). Both progress ...
FDI or Flexible Display Interface is an interconnect created by Intel in order to allow the communication of the HD Graphics integrated GPU found on supported CPUs with the PCH southbridge where display connectors are attached.
The ThinkPad 11e is a Chromebook that has a matte black chassis with reinforced hinges and corners, a sturdy lid, and a rubber bumper protecting its display in order to help it survive accidental dropping, spills, and general rough handling. It uses a quad-core Intel Celeron CPU, has 4 GB of RAM which can not be upgraded, an 11.6 inch screen ...

When data from the keyboard arrives, the controller raises an interrupt (a keyboard interrupt) to allow the CPU to handle the input. If a keyboard is a separate peripheral system unit (such as in most modern desktop computers ), the keyboard controller is not directly attached to the keys, but receives scancodes from a microcontroller embedded ...
POST cards for PCs, while originally high-priced, cost from just a few US dollars upwards in the 21st century. Some motherboards have a built-in display to diagnose hardware problems. Most also report POST errors with audible beeps, if a PC speaker is attached. Such motherboards make POST cards less necessary.
Under the Hub Architecture, a motherboard would have a two piece chipset consisting of a northbridge chip and a southbridge chip. Over time, the speed of CPUs kept increasing but the bandwidth of the front-side bus (FSB) (connection between the CPU and the motherboard) did not, resulting in a performance bottleneck.
A parallel port implemented as a PCI card.Users can use expansion cards to add deprecated legacy ports to newer computer systems that do not provide them. In computing, a legacy port is a computer port or connector that is considered by some to be fully or partially superseded. [1]
