Laptops are becoming as common as your cellular phone, and now they share the hardware industry as that of desktop computers with a number of configurable options. The features, the price, the build quality, the weight and dimensions, the display, battery uptime or that matter, the ease of the trackball. Earlier, there were hardly any configurable options available but today, we have a variety of laptops n different configurations with the process and just about anything you want.

Companies such as Intel, AMD, Transmeta and nViad, to name only a few, are making laptops a hype and reality. Intel and AMD have brought out technologies such as speed step to preserve battery power in laptops.

If you are on the move all the time, you probably need a laptop that can do all the things that you will not be able to do all the things that you will not only able you to create documents, spreadsheets and presentations, but also send and receive e-mail, access the web and may be even play music CDs or watch a DVD movie to get that much deserved break. You need laptop that is also study enough to take the bumps and joints in its stride while you are on the move.

The diagram compresses of micro processor such as Motorola power PC, Intels Pentium and Celron, AMD's K5 and K6 fanuties. The microprocessor co-ordinates all of the computers functions according to programmed instructions, ie operating system software. Input devices to enter data, here mouse, Track ball, Touch pad and keyboard are used as input. Displaying is performed with the help of LCD display and monitor, input/output port, they may be serial or USB. It uses Hard disk drive, floppy/zip drive and CD/DVD drive as data storage devices. An output device printer. Laptop can be plugged into the wall to receive AC power from the electro power grid through an AC adapter since it is portable batteries are used for power. Two types of memory RAM and ROM are used. Also consist of internal modem and wireless port if we want to connect input/output devices for specific work.

Microprocessors

Like standard desktops laptops are powered by microprocessors. The microprocessor is the basis of the laptop and co-ordinates all of the computers functions according to programmed instructions that is the operating system software. The DX-4 processor shown in the photo below is no longer used, but it is typical of modern laptop microprocessors in that it is customized for laptop used. A typical laptop processor has features that reduce power consumption and heat. For example laptop processors often run at a lower voltage and often have multiple sleep or slow down modes that significantly increases battery life. Typical laptop microprocessors include Motorola's Power PC family used in Apple Macintosh computers, Intel Pentium and Celeron families used in PCs and AMD's K5 and K6 families used in PCs.

Operating Systems

The operating is the set of pre programmed instructions that tell the microprocessor what to do. Operating systems on laptops include Windows 98/2000/NT (Microsoft) and Mac 05,depending upon the type of computer.

Memory

Just like desktops Laptops have memory both ROM and RAM. The laptop's ROM chip contains the BIOs just as it does in a desktop computers. RAM stores the application software and data files while the computer is ON. RAM differs on a laptop in that it used a different form factor that is the size and shape mof the models that carry the RAM. Manufacturers have to build laptops to be portable and to withstand move just ling durable than a desktop would ever get, so the memory modules have to be different. While some laptops have to be different. While some laptops use a standard Small Outline Dual Inline Memory Module (SODIMM) , others use the manufacturer's proprietary memory modules. Most laptops should have at least 64 MB of RAM to have sufficient memory to run operating systems and applications software. Also, some laptops allow you to upgrade the memory of your computer and come equipped with convenient access panels to plug in additional memory chips.

Disk Drives

Like desktops, laptops have various disk drive storage devices. All laptops have an internal hard disk drive , usually 6 to 20 gigabytes (GB). The hard disk drive stores operating systems, application programs and data files. Although the hard disk drive works the same in a laptop as it does in a desktop, laptops generally have less disk space than desktops and you will have fewer choices for hard disk drives in laptops. The smaller hard disk space is one of the chief limitations of laptops.
