PCI & ISA slots • Peripheral Component Interconnect (in white) is a bus where hardware devices are attached inside the computer. Common PCI cards are modems, sounds, USB, and network. USB works similarly to PCI slots. • Industry Standard Architecture slots (in black) were developed before PCI and works like them, as a bus, only they do not hold as much data. This may be why there are more PCI slots than ISA slots on the mother board.
Level 2: a secondary cache module with fast memory, SRAM, is now integrated into the main processor. L2 Cache operates faster than L1 b/c it separately stores recently accessed data. Level 1: A module that stores frequently accessed data. Data is saved to a main memory as well as in the cache for easier access. L1 & L2 Cache
Expansion Slots • These easy-to-use slots help transfer data b/w the CPU and a peripheral. • You can plug in (audio, video) and play!
Power Connector • It is exactly as its name says: this is where power comes from. • Usually come in the form of 24-pin cables, though some sockets may have 20-pin
Chipset • Responsible for transferring info to and from all circuits, adapter card connectors and disk drives. • The northbridge directs info within the CPU system, and the southbridge directs peripheral info in and out of the system.
IDE Connector Ports • Integrated Drive Electronics connects the motherboard to the hard drive
CPU Socket Heatsink Mount • Central Processing Unit, the brains of the entire system.
SATA Connectors • Serial Advanced Technology Attachment connectors are faster and smaller than ATA connectors • Serial buses carry data in bit form.
Memory Sockets • Memory modules are housed here, and are colored coded. They can be placed together as seen in the picture or spaced out.
What is the purpose of the bus? • A wired pathway b/w the two main components: RAM and the CPU. • It transfers data from one place to another, which is either inside the the system or outside, via a cable.
Back Panel of a Computer • Parallel Port connects to a printer • LAN ports link to the internet • Audio: blue = input/green= output • Speakers: black=rear & gray=middle surround sound • Mic- mono or stereo • USB ports connect peripheral hardware (camera, ext. hard drive) • Serial Port connect to peripheral hardware (like a projector) • PS/2 keyboard (purple) and mouse (green) are 6 pin connectors. • SPDIF: yellow= in/orange= out for digital audio and video interfaces
