RATIONALE
The hardware compnests are the tangible components of the  computer. A knowledge of the tangible components will enable you to understand how the parts relate to one another. It will also help you troubleshoot when you meet problems in operating computers.

Hardware
The physical part of the computer is known as Hardware. Means physical components of the computer system. Those that we can touch and having weight. In another words the parts of the computer by which a computer is made. In general Hardware is categorized according to which of the five basic computer operation it performs:
Input devices- Processors and memory- Output devices-Secondary storage devices.-Communications/networking devices.
Input Devices
These devices can be used to enter data to computer like keyboards, scanners,light pen, Bar code readers, finger print sensors, touch lcd,mouse,joystick,trackball and other pointing devices, These devices converts data  into specific form e.g. Text, Images, drawings, into a form that a computer can understand and use.
Out put devices
These type of hardware is used after the processing of data in the main system, also we can say that parts of the computer that can be used for output data are called output devices.The output of computer processing is the usable information that the user requires. This information can be presented to the user in a variety of forms, depending on the out put device. Out put devices are, Monitor, LCD, Printers,Speakers,Woofers,and etc.

Processors
CPU: Central Processing Unit: This is the electronic circuitry used in computers that carries out the instruction of a computer programme by performing the basic arithmetic
,logical,control and input output operations specified by the instructions. Modern CPU's are microprocessors
Memory
The computer's work space where application instructions and data are held during operation is called memory, also known as main memory, primary storage or RAM(Random access Memory). The capacity of these memory is very important and The speed of a computer depends on RAM. More the RAM more will be the speed. This bigger memory means bigger work space. Whatever data is held in the RAM is erased when the computer is reset or the computer is turned off. The Random Access Memory(RAM) , The amount  of memory available determines the kind of software that can be run and how much data can be manipulated. The available RAM  at Present is 512MB,1024MB(1GB), 2GB,16GB and maybe more.
The another type of memory is ROM, Aside from the RAM , the computer also has a ROM(Read Only Memory) which is used to store the boot program and other low-level information that enables the computer to start up and to recognize its hardware parts.
Storage
That type of hardware that retain data for future use or for current time is called a Storage deive. These devices may be found inside or outside the computer. There are different typed of storage devices are available in the market. But the popular devices are Optical (CD,DVD ROM) and Magnetic(Tapes,Disk). Beside these external drives,memory cards,pendrives are the example of storage devices. Any way, also this can be said that the type of hardware that hold and delet data according to user control and can access any time even when computer is off/on the data will accessible.
Communication Devices
Communications hardware, also called networking devices, is used to extend the processing capabilities of a computer system by providing a means of transferring data and applications from one computer system to another.. Communication hardware is used to link to existing comunication networks like the  internet that allow electronic transfer of information any time, anywhere

A COMPUTER MOTHER BOARD(MAIN BOARD)

A COMPUTER MOTHER BOARD(MAIN BOARD)

A Computer MB (Mother Board) Also known as the main board of a PC (Personel Computer)
This is the PCB (Printed Circuit Board) of a computer.
All the processing circuits are fitted on it.

This board is also called , Planar Board or logic board and a mobo.

The Main Thing is the CPU ( Central Processing Unit).
A CPU is the type of Hardware with in a computer that carries out the instructions of a computer program by performing trhe basic arithemetical, logical, and input/ output operations of the system.
CPU simply called a Processor.

RAM : These are called Random Access Memory. There are so many types of RAM. Like SDRAM, DDR1,DDR2,DDR3 and others.
Mother Boards Requied Power to run. For this perpose a PSU (Power Supply Unit) is used to supply the required voltage to mother board.Power supply out put is different like 3v, 5v,+12v,-12v and Neutral( Black Color).

These Power supplies converts mains Alternate Currents (AC) to low voltage regulated DC power for the internal components of a computer. Todays switched mode power supplies are commonly used. Some power supplies having manual selector for input voltage, while others automatically adapt to supply voltage.

These power supplies also can be used to charge 12V DC batteries. But this process can harm you if your not familiar with current, ampare and other usage of electronic devices. Don't charge or connect these power supplies to any out let directly. These power supplies can be used after modification. In the future we will share modified items carefully. OK,,,,,, If you want to swith on You power supply.

Connect two wires together. that are Black and Green . If you your circuits is short circuit then the power supply will automatically power off. Or if you contact 3v Orange color with black then your power supply will switched off, In this condition remove the black wire from green and connect again your power supply will work again.

So Be Careful doing every experience, Because a Small Care can save your Life......

Computer HDD Types and Inf

Computer HDD Types and Information (Hard Disk Drive)

Original Inner Side Pictures of Computer hard disk drive

Don't Open or try for any maintenance if you are not authorized or Able Hardware Technician.

Just For Your Information.

Hard Disk Drive : A Hard Disk Drive is a Storage Device that you Can Store (Save) digital Information in the form of soft copy and you can retrieve them at later. Hard Disk Consist of Platters that rapidly rotating beneath Heads. Platters are magnetic materials. A Hard disk has the ability of retaining data even when powered off.

There were Types of HDD

SATA: Serials ATA and PATA: Parallels ATA

PATA : These harddrives were used in old PC (Personel Computeres)

SATA : These hard drives is used in the latest Computers, and have fast speed like 7200 rpm (rounds per minute)

Beside These TWO Big Types 

Also HDD is Availbe in the Following Types.

1. Solid State HDD (SSD): These drives are like a memory Stick. 

There are no moving parts like SATA and PATA Drives that discussed above. The Data is stored on chip.

2. External USB HDD : These drives are portable devices and very easy to use. Just plug in usb port or wirelessly and use. 

These type of drives also used for backup computers or for network.

3.Solid State Hybrid Drives : 

These Drives has Cache and Blend The Hard Drives Capacity with SSD Speed.
