What is a slot?
Each computer device is connected to the motherboard through a special slot - slot. But what does a slot for a computer mean? The main purpose is to install additional internal cards, which include network and sound cards, video cards, modems, TV tuners, USB controllers, etc. Let's take a closer look at what a slot is and its purpose.
Slot is ...
Slot (English slot - slot) expansion - slot connector system or, as they often say, the motherboard.
As a rule, slots occupy a lot of space on motherboards. Depending on the manufacturer and functional features, the number of slots on different motherboards may vary. For example, in modern boards, individual elements of the expansion of video cards, network cards and IEEE-1394 controllers are already integrated into motherboards. This allows to reduce their dimensions to a standard called mATX.
Types of slots on the motherboard
- Accelerated Graphics Port (abbreviated to AGP). This slot is used to connect video adapters and is located close to the processor of the machine.These elements are directly interconnected with the high-speed bus.
- PCI Express x16. A fairly modern slot is also designed to connect video cards (alternative devices do not fit it). The developers assumed that this standard, having a faster bus, would quickly replace AGP, but now both slots, as well as extensions to them, are equally popular.
- PCI Express x1. Visually, this slot is much shorter than the others. These slots are in most motherboards, but mostly empty, since this interface is designed for special controllers, sound cards and video cards.
- PCI. The most popular standard used by most extension cards. The list of devices compatible with this port is very long: from various controllers to Wi-Fi adapters, tuners and receivers. On motherboards, the number of such slots can be from 2 to 6.
