Laptop computers are portable and lightweight. They have many special features, when compared to desktop computers. Laptops come with built-in batteries, which are made for long life. They're easy to carry, so they can be used easily while traveling. Lower energy consumption, memory and hard drive, wireless connectivity and optical drives are some of the special features to look for in a laptop computer.
Lower Energy Consumption
Laptops come with low power, energy efficient processors, which are designed to reduce heat and enhance battery life. Lower energy consumption doesn't compromise their efficiency. A typical desktop CPU uses 65 to 250 watts, but laptop computer CPU's use only 15 to 60 watts. As technology advances, such as the advances between the Centrino and Centrino 2 mobile processors, design improvements continue to offer faster performance and increase battery life.
Hard Drive Memory
Most new laptops come with at least 1GB RAM as of 2011. Computers with more memory run faster than those with less memory. Some of the new laptops have switched to faster DDR3 memory, which can make a significant improvements in the computer's performance. Hard drives in laptops feature 160GB to 200GB minimum size. Some larger capacity drives have 320GB to 500GB. Some high-end laptops are designed to connect to desktop docking stations when used in your regular office. Docking stations often provide additional hard drive space and external serial, parallel and USB ports.
Most new laptops come with some special wireless connectivity features. An array of ports, slots, Firewire and VGA outputs are some of the features included in the latest laptops. USB ports and Firewire connections make it possible to expand the laptop's connectivity beyond its factory configuration. As most new laptops are designed without a 1.44MB diskette drive, the USB ports allow you to share files, carry files from one computer to another, or perform computer backups using a USB jump drive.
Graphics, Optical Discs
Integrated graphics is a special feature on laptops that offers standard performance for office use. The standard integrated graphic cards are not configured for today's higher-end multimedia and gaming software. If you want additional multimedia/gaming performance, you need an upgraded high-end graphics card. Standard graphic cards have the capacity to handle online video and audio applications, and video streaming. Most laptops feature some configuration of combination DVD-R/RW or CD-R/RW optical drives, which read and write optical discs. These drives are now being replaced with high-definition Blu-ray compatible multi-format optical drives.
