AF_IC04_ The motherboard. Components and configuration. AF Unit 2 Connectors for modern-day motherboards. The main goal of this unit is to get to know the ways in which the motherboard has to communicate, both internally and externally. In order to do this you will need to know about the chipset and all the connectors laid on a motherboard layout and also about the connectors that can be found in externally in a CPU when it is assembled and running. 2.1 The motherboard chipset. The chipset (consisting of a set of integrated circuits) has traditionally been composed of two main chips (the northbridge and the southbridge) although there are several other combinations, such as a single chip or more depending on the system. The chipset is responsible, amongst other things, for the frequency of transmission between the motherboard and other components, like the processor, the memory or the storage devices. THE CHIPSET The chipset is one the most important parts in a motherboard, as it largely manages operation and communication of the board and of all the system by extent. The northbridge is usually located in the “north” part to the motherboard (the upper side) in the ATX standard. It deals with the communication of the processor with the cache memory and the central memory, and communicates with the southbridge as well. The southbridge, located and the “south” part of the motherboard in the ATX standard is the one to manage the ports, devices, storages units, expansion cards, etc. Review this webpage that contains a list of the leading manufacturers of chipsets and try and check if the one controlling your computer is in the list. You may have to open the case to view which chipset is in your motherboard, if you have not done so before. The page is held in ranker.com, where it is possible to find lots of rankings, set up with a votation system. TO KNOW MORE The leading manufacturers of chipsets. List of chipset manufacturers. AF_IC04_The motherboard. Components and configuration. Materials / Unit 2 1 Three of the chipset manufacturers: ALI, intel and nVIDIA 2.2 Internal connectors. All the internal connectors are not accessible from the outside of the case and they are mostly intended not to be manipulated, unless it is necessary to make a major update or repair in the computer, such as a processor replacement. First of all, read these definitions and explanations of the internal connectors to be found in an average computer, trying to memorize at least the names of the parts. Activity: Quizlet about connectors in a computer. Make your own quizlet listing the names and definitions of the connectors in an average computer. You can check the quizlet found in the glossary of this activity as a generic example about how to use the tool: (http://quizlet.com/44821094/flashcards) Processor connector: The zone prepared to connect the processor is known by the name of processor connector or socket. Depending on the processor family and the manufacturer the socket can have different formats. One example of socket for Intel processors is Socket T or LGA775, for Pentium D or Intel Core Duo systems. In the case of AMD processors, we can find Socket 939, for Athlon 64 or Opteron. CPU COOLERS Most desktop computers have the need to have a cooler and a fan installed on the processor, in order to keep an adequate temperature for the processor and thus a good working order for the system as a whole. A processor cooler ready to be installed. Memory slots: Memory slots are the zones where the main memory modules (RAM memory) are inserted. These memory modules can be found in different formats that depend on the motherboard and define the connexion interfaces as well as the type of connection. Their most characteristic feature is the number of pins or contacts of the connection. The most know module is called DIMM, and it comes in several generations ranging from DDR to DDR3, the latter being the latest version used nowadays. Check the next link, where there is a brief explanation of the sizes and types that can be found in desktop or laptop computers. Be sure to identify the kind of module that your computer carries. You can help yourself with the program cpu-z, reviewed previously. AF_IC04_The motherboard. Components and configuration. Materials / Unit 2 2 TO KNOW MORE Types of memory modules. Memory modules for diverse kinds of computers. Identify the memory modules depicted in the next image, and find out which one is used in you own computer. Images of several memory modules. Buses: These are a set of transmission lines that communicate the different blocks in a computer: cpu, memory and peripherals, through the mainboard. The velocity of transmission of data through the buses is fundamental for the right performance of a system, together with the chipset. SYSTEM BUS Known by the term FSB (front side bus) o simply system bus. It is the bus that communicates the processor with the chipset, and so has to offer the maximum possible performance. Peripheral internal connectors: There are several other connectors that have evolved through time, and that serve the purpose of connecting expansion cards and peripherals to the motherboard and as a result to the system. For example, you can find the PCI bus (peripheral component interconnect), that connects the motherboard with PCI expansion cards, which is mostly obsolete. There is also the PCI-Express bus that succeeded the PCI bus, and started as a graphics connector. It is very important because of its omnipresence the USB (universal serial bus), designed in the nineties to connect peripherals to substitute the old parallel and serial buses. THE SLOTS The expansion slots are the actual zones where devices such as the graphics card, the network card or others connect to the motherboard. The names and technologies of the different buses have a direct correspondence with their own slots. AF_IC04_The motherboard. Components and configuration. Materials / Unit 2 3 From left to right and from top to bottom, ISA, PCI, AGP and PCIe slots. Motherboard internal connectors: There are several internal elements in the case that must be connected to the motherboard, such as the hard disk disks and optical drives. In order to connect these devices, the motherboard has its interfaces, with the corresponding standards. The most usual are IDE (integrated device electronics) and SCSCI, for storage devices and S-ATA or Serial ATA that offers more up-to-date specifications and plug and play capacities.

The external connectors are usually called ports and they serve as interface to connect the external peripherals, such as the keyboard, mouse, printer or display. Read the next definitions about the most commonly seen external connectors in personal computers. Try to identify the connectors with the ones in your computer. USB (universal serial bus): Allows the connection of plug and play devices and supplies energy to them, making it unnecessary to use another card for this purpose. There are several types of connector and generations of the technology, ranging from the original USB specification to the much more speedy USB 3.0.

Game or joystick connector: Almost obsolete connector that permits the connection of game controllers. VGA or HDMI: Interface of the graphic card with the display. HDMI allows High Definition graphics compared to the much more aged, VGA. INTEGRATED DEVICES The most modern motherboards have built-in devices, that previously had to be added via expansion slots. These include device controllers, sound and graphics or network cards. The integration of components allows to make computers at smaller prizes, although makes them more difficult to repair. In the next image you will find the above connector plus some others which are not so common in today's computers. Try to identify all the connectors and relate this information to your own system. Note that not all of the connectors in the image are explained above. Search for the missing ones. External connectors for a desktop PC Activity: To finish with the activity, enumerate the Input/Output peripherals and devices connected to your computer, and the port where they are plugged into.
