Power Supply - Small Form Factor design,http://www.amazon.com/Genuine-Dell-Inspiron-Systems-Identical/dp/B001GJCR46/ref=sr_1_1?ie=UTF8&qid=1346943850&sr=8-1&keywords=inspiron+530s+power+supply
CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
1) Processor: Intel Pentium Dual Core E5200
(Max frequency rate = 2.5GigaHertz )http://en.wikipedia.org/wiki/List_of_Intel_Pentium_Dual-Core_microprocessors#.22Wolfdale-3M.22_.2845_nm.29
800 MegaHertz Front Side Bus
Voltage range .085 to 1.3625 Volts (DC)
Uses Up To 65 Watts of power
Again, 2.5GHz for the maximum frequency rate. ('Speed')
2) Processor socket: LGA 775http://en.wikipedia.org/wiki/LGA_775
3) Motherboard Chipset:
Intel G33 Expresshttp://en.wikipedia.org/wiki/List_of_Intel_chipsets#Core_2_chipsets
Scroll down to G33;
Northbridge chip: Intel 82G33
Southbridge chip: Intel 82801IB, or 82801IR, or 82801IH,
(ICH9, or ICH9R, or ICH9DH. Scroll down to the subheading -
Southbridge 9xx and 3/4 Series chipsets)
4) Ram Memory:
2 ram memory slots
Maximum for EACH ram memory slot is 1GigaByte
Maximum TOTAL is 2GB.
DDR2 Sdram at 667MegaHertz. (PC2-5300)
5) Harddrive: SATA - 500GigaByte
6) Optical Drive - SATA
7) Graphics: Integrated on the motherboard.
Intel GMA 3100,http://en.wikipedia.org/wiki/Intel_GMA#GMA_3100
PCI-Express x16 slot, and uses the PCI-Express 2.0 technology.
The CPU (Processor) communicates back, and forth to the Northbridge chip, (Of the motherboard chipset), through the Front Side Bus. (FSB)
The Northbridge chip communicates with the Southbridge chip, through the Internal Bus.
The Southbridge communicates with the Super I/O chipset, and the BIOS chipset, through the LPC Bus. (Low Pin Count )
One at a time in the Wikipedia search box look up,
1) Bus (computing)
2) Front Side Bus
3) Northbridge (computing)
4) Southbridge (computing)
5) Internal bus
6) LPC bus
7) Super I/O
8) PCI (Local bus) [Conventional PCI ]
9) PCI Express
Chip and Chipset are slang terms for I.C.
The GPU, or Graphics Processing Unit, or graphics chipset; can be Integrated on the motherboard, or on a separate graphics adapter card,http://en.wikipedia.org/wiki/GPU
The motherboard chipset for the Dell Inspiron 530s desktop computer, consists of a Northbridge chip, and a Southbridge chip.
[So aptly named because if you look at a motherboard as a map, the Processor, and Northbridge chip sits due North; Ram Memory slots due East; PCI slots, and Southbridge chip due South ]
The Northbridge chip handles the Faster capabilities of a computer.
Processor, Ram Memory, and HIGH-speed graphics.
AGP and PCI Express is HIGH-speed graphics.
A graphics card inserted into a PCI slot, or using Integrated Graphics, is NOT high-speed graphics.
The Southbridge chip handles the Slower capabilities of a computer.
PCI bus. (PCI expansion slots, and Integrated Graphics)
The Super I/O chipset handles the I/O devices (Input/Output), such as the Keyboard, Mouse, Floppy Drive, and anything connected to a Serial port, or Parallel port.
