Notebook Implying Laptop Small Computer With Liquid Crystal Displays

Notebook refers to a laptop computer, which is a small computer that acts as a mobile device, which can be carried to anyplace, simplifying the computing needs of people. In an age of technology it is one device that is extremely essential for doing various important tasks, which cannot always done with a desktop computer, at home or office.

Weighing around 2-18 pounds, a notebook is one, which operates on a single main battery, which can be charged and provides power back up during power failures. It is like desktop computers and does all the tasks that the former can do, but it is a mini version, which provides the option of mobile usage and also provides efficient power consumption. Liquid crystal displays are usually seen in these laptops, which utilize different kinds of memories depending on their individual requirements.

A touchpad or pointing stick can be used in a notebook along with the keypad for data input. Facilities for attaching external keypad and mouse are also provided by these devices. There are different varieties of notebooks available in the market, consisting of Thin-and-lights, mainstream and desktop replacement computers. With a screen size of 12 to 14 inches and having a weight of around 4 and 6lb is part of the thin-and-lights variety. Those with weights between 5 and 7lb, with 14.1 to 15.4inches screen, are a part of the mainstream variety.

Some notebooks are heavier and larger than the others and are generally fixed at a particular position and are infrequently carried as a mobile device. They are designed to handle more powerful operations and are therefore often referred to as desktop replacements. Gaming notebooks fall in this category. They can be used for all kinds of functions but also have certain disadvantages.

The notebook faces parts standardization and compatibility issues. Since there are a number of manufacturers who produce these devices, there is no fixed standard that is maintained by all of them. Internal form factors comprising of supply of electric voltage, motherboard layouts, internal adapters used for connecting the hard disk etc. are not standardized and differ from manufacturer to manufacturer. Due to ordinary usage and their portability, they can be easily damaged and repair costs are sometimes as high as the cost of a new laptop.

The upgradeability of a notebook is extremely limited because each manufacturer has a unique design and therefore different parts cannot be swapped between competing brands. But their usage in the modern world has increased and people use different types of laptops, depending on their personal and professional needs, having different performance and price levels. Notebook
