A graphics card is usually an external expansion card that produces a continuously fed output image to a video display unit. In graphics card terminology, this is sometimes called an accelerated graphics card, highlighting the difference between this type of card and its more conventional integrated graphics card. Graphics card output varies according to the chip set up and output requirements. For example, on modern motherboards, all active graphics card outputs are controlled through a single command register that does most of the work for you. On the other hand, traditional graphics card output mapping is done by hardware such as discrete cards or integrated graphics controllers. Either way, a graphics card under 5000 has several parts that need to be synchronized properly in order for your computer to take advantage of its potential.

One of the first pieces of information you should know when investigating the various types of graphics cards is what type of interface the card uses. There are four basic interface types: AGP (AGP slot type), PCI (PCI slot type), IDE (IDE slot type) and Floppy/Flash. You can also have a fifth, parallel interface that supports parallel ports on many computers. There are many other types of interfaces available, but these will be the most common in office equipment, consumer electronics and enterprise software applications.

The next piece of information you need to know is how the graphics processing unit (AGP) itself works. The AGP is a modular, two-level memory card with the primary function of holding instructions for programmable logic gates (PLGs) on the edge of the system memory. Instructions for execution are stored on the lower level of the AGP, where the gate is operational. As the computer uses the AGP to access programs, it indirectly references the lower level of the memory where the instructions are stored. If the target computer happens to have a different AGP than your current system, you may encounter a performance problem as a result of a non-matching PLG or a non-instruction-rewarded instruction.

The graphics card's CPU is the main component of the system and is responsible for executing the computer's commands. When an application is started up, the operating system searches through the CPU's memory to find instructions for executing the application. When a match is found, the application is executed. The actual graphics processing unit (gpu) and the main memory (RAM) work together via the gpu. The gpu is the only part of the computer that needs access to the target CPU's resources.

To understand how the gas and the ram work together; it is important to understand how an ordinary computer actually works. The central processing unit (CPU) is the processing unit of the computer that contains several microprocessor elements (instruction processing unit (IPU) and associated registers and logic gates) that operate in an instruction mode. The processing unit is accessed by the PCV, which is the main control terminal of the CPU. When instructions are issued, the PCV sends a request to the gpu to start the corresponding task.

The response from the gpu is to send an instruction to the target processor. The target processor responds by executing the instruction and sending the desired execution commands to the graphic processing unit. In the case of a graphics card, this will result in transferring the video data from the host computer to the graphics card. Transferring the data requires the communication between the gpu and the host computer. This is done via the PCI bus that is a standardized connection that carries data between the computer and its peripherals including the graphics card.

A discrete graphics card on the other hand is built on the same architecture as the integrated graphics card. It is the only card in a computer that is not built on a motherboard but rather on its own. This is because it is an independent component that does not need an external power supply like the other motherboards do. A discrete graphics card therefore is easier to upgrade. Motherboards on the other hand cannot upgrade the graphics card because it can not interface with the internal chips that are involved in the process of transferring data.

To summarize, an integrated graphics card or a discrete graphics card has its own interface which connects directly to the ram of the computer and transfers the video memory, electronic signal processor, caches and all other data that are involved in the digital signals. A discrete graphics card however is connected to the computer display through the PCI bus, which carries the communication between the computer and its peripherals including the graphics card. This makes it easier for the user to replace or upgrade his/her old video memory if he/she finds it hard to upgrade the digital signals in their computers.
