What is Motherboard ?

Alternatively  referred  to  as  the  mb,  mainboard,  mboard, mobo,  mobd, backplane  board,  base  board,  main  circuit  board,  planar  board,  system board,  or  a  logic  board  on  Apple  computers.  The  motherboard  is  a  printed circuit  board that  is  the  foundation  of or  at  the  bottom  of  the  computer a  computer,  located  on  the  back  side chassis communication  to  the CPU , RAM , .  It  allocates  power  and  allows and  all  other  computer components. 

Motherboard  overview above first  is  a  picture  of  the ASUS P5AD2hardware E  motherboard  with  labels  next  to  each of  its  major  components.

What is RAM (Random Access Memory)?

What is RAM (Random Access Memory)? 

Alternatively  referred  to  as  main  memory,  primary  memory,  or  system  memory, Random  Access  Memory  (RAM)  is  a  hardware  device  that  allows  information to  be  stored  and  retrieved  on  a  computer.  RAM  is  usually  associated  with DRAM ,  which  is  a  type  of memory  module .

Because  information  is  accessed randomly  instead  of  sequentially  like  it  is  on  a CD or hard  drive can  access  the  data  much  faster.  However,  unlike ROM ,  the  computer or  the  hard  drive RAM  is  a volatile  memory  and  requires  power  to  keep  the  data  accessible.  If the computer  is turned off,  all  data contained in RAM  is lost.

What is Software and its Kinds

Parts of Computer

Parts of Computer: 

There are two basic parts that make up a computer.  Hardware: Hardware refers to the physical elements of a computer. This is also sometime called the machinery or the equipment of the computer.

 Examples of hardware in a computer are the kyboard, the monitor, the mouse and the central processing unit. However, most of a computer's hardware cannot be seen; in other words, it is not an external element of the computer, but rather an internal one, surrounded by the computer's casing (tower). 

A computer's hardware is comprised of many different parts, but perhaps the most important of these is the motherboard. The motherboard is made up of even more parts that power and control the computer.

  

In contrast to software, hardware is a physical entity. Hardware and software are interconnected, without software, the hardware of a computer would have no function. 

However, without the creation of hardware to perform tasks directed by software via the central processing unit, software would be useless.  Hardware is limited to specifically designed tasks that are, taken independently, very simple. 

Software implements algorithms (problem solutions) that allow the computer to complete much more complex tasks.  Hardware is basically anything that you can touch with your fingers. 

• Computer Case 

• CPU (central processing unit...Pentium chip) 

• Monitor

• Keyboard & Mouse 

• Disk Drive, CD-ROM, DVD,  

• Hard Drove 

• Memory (RAM) 

• Speakers 

• Printer 

Input / Output Devices

Input / Output Devices: 

Input Devices:

An input device is any hardware device that sends data to a computer, allowing you to interact with and control it.  The most commonly used or primary input devices on a computer are the keyboard and mouse.

However, there are dozens of other devices that can also be used to input data into the computer. Below is a list of input devices that can be utilized with a computer or a computing device. 

Following are some of the important input devices which are used in a computer − • Keyboard • Mouse • Joy Stick • Scanner • Microphone • Card Reader • Bar Code Reader 

Output Devices: 

An output device is any peripheral that receives data from a computer, usually for display, projection, or physical reproduction, an output device that can make a hard copy of any information shown on your monitor, which is another example of an output device. Monitors and printers are two of the most common output devices used with a computer.  Following are some of the important output devices used in a computer. • Monitors • Printer • Speakers • Headphones • Modem • FAX machines.

1. What is Computer ? Computers  are  machines  that  perform  tasks  or  calculations according  to  a  set  of  instructions,  or  programs.  
2. The  first  fully electronic  computers,  introduced  in  the  1940s,  were  huge machines  that  required  teams  of  people  to  operate.  Compared to  those  early  machines,  today's computers  are  amazing. Not  only are  they  thousands  of  times  faster,  they  can  fit  on  your  desk,  on your lap,  or even in your pocket Computers  work through an interaction of hardware  and so ftware. Hardware  refers  to  the  parts  of  a  computer  that  you  can  see  and touch,  including  the  case  and  everything  inside  it.  
3. The  most important  piece  of  hardware  is  a  tiny  rectangular  chip  inside  your computer  called  the  central  processing  unit  (CPU),  or mi croprocessor.  It's  the  "brain"  of  your  computer — the  part  that translates  instructions  and  performs  calculations.  Hardware  items such  as  your  monitor,  keyboard,  mouse,  printer,  and  other components  are  often called hardware  devices,  or devices.
