Its for expanding that computer's ability.
You can add stuff like a tv tuners, sound cards, network card, wireless networking, more ports, video cards, more sata or IDE controllers, etc.
Mind you that for video cards is suggested to use pci express x16, or AGP x8 if you have an old motherboard.
There are also pci express x1, which can do that same thing as the pci slot, but has a much faster transfer rate.

Also newer PCI express x16
These are the expansion slots on newer motherboards introduced after AGP was phased out.
Commonly used to support the computers GPU (Graphical processing unit) or the Video Card

∙ 9y agoPCI Express or PCI-E is a high-speed, serial system bus standard. It is much faster than PCI. It uses the serial standard to prevent problems that cause lower performance like cross-talk and timing skew. PCI-E card can have different length connectors since it uses signal lanes and faster devices use more lanes.

the small ones are used for other stuff (sound card, TV tuners...)

What expansion slot replaced the PCI and AGP slots?
pci express (PCIe)
What is A small expansion slot about the size of a PCI express x1 slot?
AGP
What expansion slot has largely been replaced by PCI Express?
AGP was the most common before the PCI Express
What expansion slot type employs serial communication pathways?
PCI Express
What type of expansion slot is preferred for today for high performance graphics cards?
PCI or PCI Express
Which type of expansion slot is used solely for a video card?
pci express or AGP
Will a PCI x16 graphics card work in a normal PCI slot?
A PCIe x16 graphics card will not work in a normal PCI slot. PCIe or PCI Express is a new standard in expansion interfaces. PCIe is physically and electronically incompatible with PCI slots.
How many PCI Express slots does an Optiplex GX270 have?
Most GX-270 towers have one 4x PCI-e slot, although I believe some earlier ones had AGP. Not sure about the slim desktops. You'll have a green expansion slot if it's PCI-express ...
Can you use pci express 2.0 in pci express 16 slot?
You cannot use a 2.0 pci express card in a pci express slot because the technology is newer. For example: It would be like putting a playstation 3 game into a playstation 2 console.
What type of expansion slot do and slower devices use?
The original IBM compatible parts used an 8-bit ISA slot. After that, they moved to a 16-bit ISA slot. There were other things like a VESA slot that didn't last for long. Then there were PCI slots (not express), and AGP was a faster video card slot standard. Then PCI-express replaced both PCI and AGP.
Can you replace a PCI slot with a PCI Express slot without replacing your motherboard?
No. Because the architectures (design) are not equals and the PCI Express have more speed on Its bus.
Will pci express 2.0 slot support pci express 1.0 card?
It should.
