What is a motherboard ??

A motherboard (also known as the mainboard, system board, planar board or logic board) is the main PCB found in computers and other expandable systems. It holds many of the crucial electronic components of the system, such as the CPU, memory, and processor.

The function of the computer motherboard is to act as the main circuit board that connects and communicates to all the devices and components attached. The motherboard also facilitates the communication of devices with each other. Motherboards are designed around the type of central processing unit (CPU) that will be installed. Because motherboards act as the base for all other computer components, the number of PCI slots, USB headers, memory slots, SATA headers, and other slots should be checked ahead of time before building a personal computer.

A typical desktop computer has its microprocessor, main memory, and other essential components connected to the motherboard. Other components such as external storage, controllers for video display and sound, and peripheral devices may be attached to the motherboard as plug-in cards or via cables, in modern computers it is increasingly common to integrate some of these peripherals into the motherboard itself.

An important component of a motherboard is the microprocessor's supporting chipset, which provides the supporting interfaces between the CPU and the various buses and external components. This chipset determines, to an extent, the features and capabilities of the motherboard.

What are the reasons for mother board failure? 

  1. First and most common reason is heat. Keep cabinet ventilated to prevent high temperature inside the box.
  2. Check your Fan speed, if it is not normal then hurry up!! repair it.
  3. Dust also cause problems. clean your pc regularly and prevent it from the dust environment.
  4. Use static power supply, put power controller to prevent your pc from unregulated ac power supply.
  5. Do not install the software that cause damage your system. Use only trusted and light software if possible. 
  6. Do not play the games which require high processing power ( before installation, see whether it is suitable to your configuration or not.)   
  7. Keep your pc free from viruses and worms , they put extra overload on processor.
  8. When everything is going well, don't ever upgrade BIOS without right upgrade files.
  9. Do not play with BIOS and RAM if you don't know properly about it.

    How to terminate processes in ubuntu??

    In windows we can easily terminate the process by
    • ctrl+alt+del 
    • right click on program name
    • go to process
    • end process.
    but in Linux , it is not that much easy, u have to follow the terminal steps:

    example: to close firefox process.
    • Open terminal (ctrl+alt+t)
    • type command : ps auxwww | grep firefox
    • u will get some table , in which u find process IDs
    • type command : kill 2348 (note: 2384 is process id, it is different each time )
    Kill process is very useful when your program is not responding.
