What is Motherboard ?

• The moth­er­board is a print­ed cir­cuit board that is the most impor­tant part of the System.
• Every com­po­nent of the sys­tem con­nects to the moth­er­board direct­ly or indirectly.

Types of Motherboard

• The dif­fer­ent types of moth­er­board are:
  • Desk­top motherboard
  • Serv­er motherboard
  • Lap­top motherboard

Important Points About Motherboard

• The lead­ing man­u­fac­tur­ers of chipsets include intel, SiS, VIA and AMD.
• The chipset on a moth­er­board is a group of inte­grat­ed cir­cuits and micro­proces­sors and also deter­mines the func­tion­al­i­ty of a motherboard.
• The final solu­tion came when the chipset man­u­fac­tur­ers start­ed using a new approach: using a ded­i­cat­ed high-speed bus between north and south bridges called DMI and con­nect­ing the PCI bus devices to the south bridge.
• The North Bridge is replaced by the Mem­o­ry Con­troller Hub (MCH) and the South Bridge is suc­ceed­ed by the I/O Con­troller Hub (ICH).
• The dif­fer­ent com­po­nents on the moth­er­board can be clas­si­fied as:
  • CPU Sock­et
  • Mem­o­ry Slots
  • Super Input/Output Chip
  • BIOS Chip
  • CMOS Bat­tery
  • Expan­sion Slots
  • CPU Volt­age Regulators
• The North­bridge and South­bridge which con­sti­tute a mod­ern chipset are the most impor­tant com­po­nents on the motherboard.
• The moth­er­board has a CMOS bat­tery that pro­vides back­up pow­er to the CMOS.
• You can con­nect dif­fer­ent parts of the sys­tem to the moth­er­board using the con­nec­tor and expan­sion slots.
• The jumpers on the moth­er­board enable you to con­fig­ure the motherboard.
• You must fol­low the instruc­tions in the moth­er­board man­u­al when per­form­ing con­fig­u­ra­tion, instal­la­tion or trou­bleshoot­ing of the moth­er­board.
