Slots used in Computer System
Slots or expansion slots are used to insert add-on-cards to motherboard, that enables additional features like improve graphics by adding an additional graphics card or improve the sound system by adding a sound card. But in earlier motherboard (passive) all components are added through slots.
1. ISA (Industry Standard Architecture)
- 8bit or 16 bit
- Black colour slots
- Used in old motherboards to add components like display card, sound card etc.
2. VESA(Video Electonic Standard Architecture)
- Brown coloured slots
- It comes only with the ISA 16bit slot
- Used in old mother board for add display card.
3. AMR(Audio Modem Riser)
- Smal brown coloured slot
- Used to connect AMR modem
4. PCI slot (Peripheral Component Interconnect)
- 32bit and 64 bit
- White colour slots
- Used today for add display cards, sound cards, network cards, internal modem.
5. AGP(Accelerated Graphic Port)
- If we need more graphics display for an application like photoshop, we can add an AGP card
- Brown coloured slot
- It is used to connect graphics card
- Provides high resolution
- Faster than PCI cards
6. PCIe(PCI Express)
- Faster than AGP, if we need high graphics support display for application like animation, we can use PCIe.
- PCIe is available only in latest motherboard.
