CHIPSET

 Chip sets decide CPU slots count Type of CPU slot Type of DRAM Number of USB ports Two types of chip-sets are used in CPU's North Bridge . Functions of North Bridge South Bridge.  Functions of South Bridge Important duties of chip-set Segregates duties of multiple CPUs (if available) and assign jobs to processors. To discipline data from shared bus to system bus, a bridge is required. Bridge is included in chip set. Independent device timing is included in chip-set:                                                                     When two or more hard disks are connected, Independent device timing is used to retrieve  data  from each and every hard disk at their own speed instead of slower one’s speed.   DMA support:              ...

Mother Board Form Factors

To do system board upgrades & provide better recommendations to clients, technicians need to know their form factors. 1. AT Form Factor - Advanced Technology i. Invented by IBM in the early 1980's ii. Around 12" wide * 13" deep iii. Only designed to handle keyboard and monitor, lack of external ports required.  2.     ATX Form Factor - Advanced Technology Extended i. Designed by INTEL in 1995 ii. Around 12" * 9.6" in size iii. Built-in double high external I/O connector panel, hence external ports can be located directly on the board iv. Single main keyed internal power supply connector, hence the power connector is easy to plug & can't be installed incorrectly. v. Relocated CPU & memory next to the power supply which improved airflow cooling. Also reduced the interference with any bus expansion cards. vi. Relocated internal I/O connectors for the hard drives & the floppy drives near the drive bays to shorten the c...
