Notebook is a smaller version of the desktop computer. The concept of laptop was to make a device that could use the same software of a desktop computer, but much smaller in size to enable mobility and support mobile computing (ability to use the computer while in transit). A notebook computer, sometimes called a laptop, typically usually weighs around 2 to 17 pounds (1 to 8 kgs) depending on the make, materials and different other factors that come into play such as the parent company etc. It is 3 inches or less in thickness. Notebook is a small mobile personal computer that has components that are similar to their desktop counterparts but are optimized for mobile use and efficient power consumption. Notebooks usually have a built-in keyboard and typically employ liquid crystal displays (LCD). However, all laptops have power management features to extend battery life, or conserve battery power when battery is low.

Notebook generally runs on a single main battery and is capable of doing the same tasks as a desktop computer can. It charges the battery and in the meanwhile supplies power to the laptop too. Notebook are less powerful than their desktop counterparts at the same price. This is because of the fact that most parts used in desktop computers are miniaturized to fit into the slim notebook version of the machine. A notebook differs from a desktop PC in terms of power supply, display, and the type of input devices it uses. Notebook processors usually have multiple sleeps, meaning slow down modes which help in increasing battery life and can also run on low voltage.

Notebook computers generally cost more than desktop computers with the same capabilities because they are more difficult to design and manufacture. The most important advantage of a notebook is its portability. One can work with ease anytime and everywhere. Also, access to wireless networking in public places is making notebooks more and more useful.

The first notebook was arguably the GRiD Compass 1101, released in 1982 by Bill Moggridge. It was enclosed in a magnesium case, and could run on batteries. It featured the clamshell design where the flat display folded shut on the keyboard. The first commercially successful notebooks were from the SupersPort series from Zenith Data Systems (ZDS)

Notebooks are the rage of the new generation today. No matter what the purpose one might have for using a notebook, it seems that mobility will always seem to be the main reason for such a product purchase.

Computing on the move has been a focus area for a lot of Information Technology Companies for years. The idea of being able to work while on the road is extremely fascinating. A notebook, also known as a laptop, which may also be understood as a mobile computer has been the solution for these portable computer related tasks.

History

It is a little hard to determine which is the first notebook or portable computer ever made. The Osborne 1 is considered by most historians to be the first true portable computer or notebook. This was produced by Adam Osborne in the year 1981. It featured a 5 inch screen, modem port, floppy drives, few bundled software programs and a battery pack. The total weight of the notebook was about 11 kgs. Gradually after this Epson, Radio Shack, IBM, Apple Computer etc. all came out with a portable computer. IBM`s IBM PC convertible introduced in 1986 was a true laptop computer. This computer ushered in the laptop area. Since these early models, notebooks have seen tremendous development.

Features and Functioning

Notebooks have the identical major components as Desktop PCs: microprocessor, RAM, operating system, input/output ports, hard disk drives, speakers and sound cards, and speakers. However, all laptops have power management features to extend battery life, or conserve battery power when battery is low. A notebook differs from a desktop PC in terms of power supply, display, and the type of input devices it uses. Notebook processors usually have multiple sleeps, meaning slow down modes which help in increasing battery life and can also run on low voltage. Hard disk in the notebook also functions in the same way as it does in Desktop. These are slower in speed and have lesser capacity.

In addition to hard disks, notebooks also have options for removable disk storage system such as Floppy Discs, CDs and DVDs. A notebook also has various input/output ports that enable you to connect to various peripherals. Most notebook computers today feature built-in modems and Ethernet for external connectivity. Infrared ports for wireless connectivity are also becoming very popular. One of the most critical components in a notebook is its battery as it works on battery power for usage while on move. Battery life offered is different for each device as it depends on the configuration and power management features implemented. All notebook computers come with an in-built LCD screen for display output. For Input, notebooks are featured with built-in keyboards for text inputs. As far as pointing devices are concerned, notebooks use one of the three-Trackball, Pointing stick, Touchpad.

Advantages & Disadvantages of Notebook

The most important advantage of a notebook is its portability. One can work with ease anytime and everywhere. Also, access to wireless networking in public places is making notebooks more and more useful. The counting of disadvantages for a notebook always starts with its high cost. Not only the initial cost, its parts are also expensive and are not interchangeable. Notebooks have a lesser storage capacity and its processor usually works at a lower speed when on battery power. Notebooks are also prone to theft due to its portability.

Future Directions

With falling prices and acceptance of new technologies, we can expect to see a significant increase in demand of notebooks. Vendors are also working on the design of the notebook to make it stronger so that it can withstand jerks and shocks. New technologies are being integrated into the notebooks to prevent failure and data loss. Mostly used by corporate firms, professionals and businessmen, vendors are now targeting students and home users as well because of increasing affordability of these devices.

So the emergence of this new usage category is definitely on the cards. This means there is a huge potential for notebooks in the coming future and the price cuts offered with technological improvements are sure to fuel growth.

The term Notebook computers and laptop computer is often used interchangeably. However notebook computers are smaller, lighter and costlier than laptop computers. You can carry this computer with you when you are away on a business trip, can watch movies and access internet also.

The first notebook computer which was launched in the market in 1981 was expensive and was not as versatile like present day computers .Portable versions of laptops were launched in the market by IBM and Epsom in 1983.

With introduction of Windows 95, the world of notebook computers took a giant leap forward and was now able to compete with other personal computers because of the operating system and the advancement of technology. Prices of these computers started falling, attracting more consumers. Life of battery improved and acids were no longer required. The notebook computers now consumed less power and could hold more data.

Notebook computers come in various sizes. For a quick reference, have a look at the following figures (without power adaptors and accessories): Tablet PC - it weighs less that 3 lbs; Ultra Portable - it weighs less than 4 lbs and less than 1.3 inches thick with size between 10 and 11 inches; Thin and Light - it is between 1 and 1.4 inches thick and weighs between 5 to 7 lbs with size from 11 to 14 inches; Desktop replacements (Largest) - it is 1.5 inches thick and heavier than 7 lbs. Size between 11 and 13 inches.

Some important points are listed here which may help you to have an informed purchasing decision:

Size and Weight: The point to remember that while choosing a very lightweight and small size, you may have to sacrifice some items such as drives. So you have to decide what you want.

Processor: Note book processors perform like desktop processors. Dual core processors carry multitasking and are common. Notebook processors directly impact the battery life and performance of the computers. For Intel premier processor, higher the number, the faster it will process. The rotational speed of the disk also affects the performance of these computers.

Memory (RAM): For Windows XP and Mac OS X, at least 256 MB is required. However the capacity of RAM is increasing with new varieties of notebook computer and in some machines it is 2 GB even!

Displays and Video: In a notebook computer video consists of video processor and display. Again the display consists of native resolution and screen size. But portability will be reduced with larger display. These days the popularity for the wide screen displays is increasing. Performance of PC gaming and 3D graphics will be determined by graphic processor.

Drives: Optical drives play an important role in notebook computers. These may be simple CD ROM drives to the high definition DVD burners. Most notebook computers these days are equipped with a dual layer DVD burner.

Connections: Wireless Fidelity (Wi-Fi), 802.11a, 802.11b and 802.11g, Fujitsu lifebook N6010 having trimode of 802.11a/b/g, etc are different wireless system available with notebook computers. Transferring rate of data depend on the type of wireless connection chosen.

Battery Life: Notebook computers come with four cell, 6 cell, and 8 cell batteries. Normal battery life is 2 to 3 hours. However 5 or 6 hours battery life is also available these days. Generally, the bigger the notebook computer, the lower is the battery life.
