A laptop, also known as a notebook, is typically a small, lightweight portable personal computer, usually with a light weight aluminum-based laptop lid with an open-type keyboard and a small screen on the inner side of the lid. The alphanumeric keypad is usually touch sensitive and is usually located above the hardware keys for operating systems such as Windows. The laptop lid is usually hinged in the front and can be opened to access the internal computer parts. Laptops are commonly used for basic computer tasks such as word processing, sending email and surfing the internet. As time goes by, laptop popularity has increased and several manufacturers have entered the market to produce more advanced laptop models.
One of the most basic models of laptops available in the market today, the basic laptop computer, may be powered either by the main battery or by an external AC/DC power supply and includes a standard keyboard and mouse. Advanced laptops often incorporate different features such as high definition video, wireless Internet and high resolution audio. All these features cost extra money but are definitely worth the extra investment.
Laptops have revolutionized how people communicate on the go and for those who work on a desk at their office, they allow a flexible workspace. On the other hand, for those who travel extensively, they are a practical substitute for desktop computers. Here are some things to consider when buying laptop computers:
There are four main areas to check when purchasing a laptop. These are external ports, USB, motherboard, and hard drive space. Many laptops are equipped with standard sized USB ports that connect to a host computer via a USB port or that accept either Mini-DVD or DVD disks. An external USB port is useful to connect a portable USB flash drive or to connect external peripherals such as printers, cameras or scanners. The size of the hard drive is an important factor because many laptops have hundreds of gigabytes of memory, and additional storage devices require expansion memory.
When it comes to the keyboard and the trackpad, which are used for inputting characters into the laptop’s Windows system, many personal computers have similar functionality compared to laptops. However, most desktop computers have additional buttons on the right side of the laptop keyboards for additional functions, while laptops have separate function buttons on each side. This feature makes the right side of a laptop keyboard much more user-friendly than that of desktop computers. Another function difference between laptops and desktop computers is the placement of the mouse buttons, which are usually located in the centre of a personal computer’s keyboard.
In terms of processing power, the main difference between laptops and desktop computers is the amount of processing power dedicated to central processing unit (CPU). Although laptops generally offer higher performance than desktop computers, they consume less power. Laptops generally come with less powerful processors and therefore consume less energy. Some of these laptops have up to six times the processing power of typical desktop computers.
There are some notebooks that can be taken with you virtually everywhere. However, the battery life for laptops is generally shorter when compared to desktop computers. This is because notebooks are used for specific applications and tasks. Therefore, notebooks generally come with less powerful processors, as well as slower processors that consume less energy. Also, the performance of some applications and tasks are lower when used with notebook computers over desktop computers.
Notebooks also differ in terms of their networking capability. Notebooks can work well with wireless networks, but this depends on their manufacturer. Manufacturers of wireless notebook devices usually provide software packages that are necessary for a network to function. Notebooks are generally less expensive than desktops, but prices have been dropping in recent years. If you are interested in buying a laptop, it is important to take the time to compare laptops usually offered by several different manufacturers.
