					Computers are probably responsible for more anger therapy sessions than golf games
and three-year olds combined. A necessity for modern life, laptops come in a
befuddling array of screen sizes, processor capabilities, memory capacity and more,
sending the geeks to heaven and the rest of us to the corner. But this discrepancy need
not be. Buying a laptop, especially for the first time, can be an enjoyable and
educational experience. Here 鈥檚 the first-time buyer 鈥檚 guide to laptops.
 Laptops (notebooks) are personal portable computers. Each computer has a set of
external and internal components. External components affect the user 鈥檚 physical
interaction with the device, while the internal components regulate the computer 鈥檚
behavior.
 The Screen
 The LCD screen displays information. Large screens (15-19 inches) are easy to read
and typically have high resolution, such as the Sony Vaio VGN-A series, but do not
have the portability of small screens (10-14). Some laptops, including Toshiba laptops,
have touch-screen capability.
 The Keyboard
 The keyboard and touch pad are the user 鈥檚 venues for inputting information.
Unbeknownst to many PC users, not all keyboards and touch pads are equal. Cramped
and rickety designs may generate frustration, which leads to speedy fists and
unwelcome expletives.
 Many keyboards also come with quick access buttons, which allow the user to
quickly regulate volume, screen brightness, and more.
 The Ports
 Laptops come with a gamut of ports. The most important include the following:
 鈥?Ethernet port; 鈥?High-speed USB port and FireWire; 鈥?PC card & SD card
reader; 鈥?S-video and HDMI; 鈥?Microphone and headphone jack; 鈥?eSata;
鈥?Modem; 鈥?Optical drive
 The Hard Drive
 The hard drive (HDD) is the physical disk that stores data. Its memory is usually
measured in gigabytes (GBs). Cheap netbooks offer approximately 80 GBs, a bare
minimum for most people. 200-250 GB is more than enough for most users. Shop for
hard drives rated 5400 rpm and above.
 The Processor
 The processor (CPU) is the vibrant brain of the computer. And, like human brains,
the bigger and faster, the better. The processor should also have at least 500
megabytes (MB) of RAM, with 1-3 GBs as a target.
 The Graphics Card
 For the serious PC gamer and his friends 鈥?wait, just the PC gamer 鈥?a fast,
capable graphics card is essential. Integrated graphics cards are basic and more than
enough for the average user; dedicated graphics cards are required for heavy-duty
multimedia applications.
 The Extras
 And what pink laptop is complete without a laptop bag? Warranties, laptop bags,
pre-installed operating systems and more are all fantastic perks that spice up the
shopping experience.
  So get a superb laptop and leave the anger management therapy to stricken parents
and golfers.
  Peter can help you with all your PC, TV and Gadget needs. Whether you're looking
for a Sony vaio, or look at pink laptops or simply want to find out more about the
latest Toshiba laptops and laptop bags. Let Peter be your guide to all things electrical.
