What is Computer Hardware?

Computer hardware is the physical components of a computer, whereas the data and computer files are referred to as the computer software. The computer hardware is called this because it is not often or easily changed, unlike the software, which is updated and changed frequently. Home computers usually consists of several hardware components, including the motherboard, which holds the central processing unit, and the RAM. Personal computers also consist of power supply, which holds a transformer, fan and voltage control, as well as video display, computer device controllers, which connect to things such as scanners
Or printers. You’re computer hardware also consists of the CD-ROM, DVD-ROM, floppy and hard disk drives, a sound card and a modem for online dial up connections.

Hardware also consists of several independent pieces, which include the keyboard, the mouse, gaming devices such as joysticks, web cameras, scanners, printers and speakers. These are the parts of the computer hardware that you are probably more familiar with. Computer hardware is designed with performance in mind, but also focuses around weight, appearance, size, reliability and power consumption.

Computer Hardware continues to evolve at an exponential rate. Scientists are constantly trying to improve on various types of computer hardware, in hopes that one-day computer will be small brain implants. If this sounds too far fetched then think again. We already have the ability to control electronics by electronic brain impulses alone. If you think about it, the brain is really just an organic computer. Our memory is like a hard drive and our synapses are like the circuitry of a motherboard. I believe that one-day computers will be living organisms, mini brains in a box with 3d displays and completely controlled by our thoughts. Until then, enjoy the hardware you have!

Laptops are gaining in popularity these days. Almost everyone is carrying one now either for work or entertainment. Laptops with the latest technology are introduced to the market everyday and these new laptops come with a huge price tag. However, that does not mean you cannot get a good and cheap laptop.

Buy cheap laptop with older technology

Rapid advance in technology makes it meaningless to buy the latest technology at a high price. When laptop with wireless capability first came to the market, a unit with this technology can cost up till US$2500. NOw after 2 years, you can get a relatively fast centrino laptop for less than US$1000

Buy used or refurbished laptop
The depreciation of a laptop value is so high, that after one year in the market, a laptop can easily lose half its value. So if you are looking for a cheap laptop, look for one which is close to one year old. Not all used laptop are in bad condition. You will be surprised to find that some used laptops are still in good condition because their owners are power users or gamers.

Buy laptop from power users or gamers
I like to buy electronic gadgets including laptops from hard core power users or gamers. Let me share with you why. Gamers or power users usually require the latest and most powerful technology to run their games or power hungry applications. They often will not settle for second best. They also have the tendency to chase after the latest technology. So after one year, they will be bored of what they have and will look to sell off their laptops so that they can buy a new one. Now if you are looking to buy cheap laptops with up to date technology and you happen to have friends who are gamers, do ask them if they are looking to sell off their laptops. Who knows, maybe you can buy a good and cheap laptop from them.

Scan through gaming forums and local gaming community
if you do not already have friends who like to play computer games, then scanning through gaming forums on the internet is another way to get good and cheap deals for used laptop. Internet makes it easy for you to do this. Go to google.com and start searching for gaming forums. Visit each and everyone and see if they have a Trading Section. You will definitely find many post from gamers looking to sell their gaming laptops.

Scan through local bulletin boards
Do scan through local bulletin boards near you for cheap deals on laptop.Especially if there are software companies around the area. Software companies do offer their used computers or laptops for sale when their software projects end. I personally had gotten a few good deals for my family and friends.

Look for cheap laptop with at least 512mb memory
This is especially important for used laptop. If the processor speed is slow, then having more memory can compensate for the lack in speed. In fact, The size of memory plays a big part in determining how fast a laptop runs an application. Just by increasing the memory size, you can see a huge difference in speed. A cheap laptop with at least 512mb memory can run most non graphic intensive application easily.

Get cheap laptop from reputable manufacturer
This is very important because if you are buying used laptop, then the chances of requiring servicing is higher than a new laptop. So if you buy from a reputable manufacturer, you will save alot of trouble and time if your laptop do require servicing.
