Desktop Pc

The Desktop PC has been ruling the technological world for the last 4 decades. Over the years these computers have evolved from bulky and hefty machines to sleek, attractive set-ups with a CPU case, an LCD monitor, a keyboard and a mouse. Essentially, the term 'desktop PC' refers to what we commonly call a 'CPU'. However, the CPU alone is useless, without a monitor and other peripherals like a keyboard and a mouse.

The standard components of a desktop PC are the processor, the RAM, the hard drive, the optical drive, the graphics card and the connectors.

• AMD and Intel are the 2 main processor-makers today. The processor is the brain of the computer and handles all its tasks.

• The RAM is a temporary memory which stores all active programs on the computer.

• The hard drive is the place where all files, and even the operating system are stored.

• Optical drives for playing CDs, DVDs and Blu-Ray discs can optionally be integrated within the computer.

• All sorts of display signals are handled by the graphics processor in the PC.

• Connectors of various types enable interfacing with other devices. Some of the common connectors are USB, IEEE 1394 (FireWire), eSATA, audio jacks and media card readers.

There are many players in the desktop PC making field - Dell, Acer, Asus, Sony Vaio, Apple, IBM, HP and Lenovo, are a few of them.

Will laptops beat desktop PCs?

Though laptops today offer almost all functionality of a desktop PC, the latter still has scope and will not be ousted by the portable workstations. In order to enhance mobility, the laptop incorporates components that are not as powerful as that of the desktop PCs. Portability restricts the upgradation of laptops beyond a certain limit. On the other hand, be it the hard drive, the CPU or the connectivity options, it is more easy to upgrade a PC than its portable counterpart. Moreover, the battery life of a laptop plays an important role in its construction, whereas, for a desktop PC runtime life is not much of a concern, as it draws power directly from the mains. There is one more field where the desktop PC scores better than the laptop - the parts of desktop computers are standardized. Hence they are more easily replaceable. Many offices and homes are still sticking with the desktop PCs. Laptops are more of an "on the go" device. However, if portability is not a criteria, then be assured that laptops can never set that adrenalin rushing as much as the desktop PCs, when it comes to gaming!

Ergonomics

This is an essential subject that has to be taken into consideration by every individual who uses a desktop PC. Arranging the computer properly, and sitting in a comfortable posture while working on it, is very important. If proper care is not taken, people who work for long hours on computers can develop RSI (Repetitive Strain Injury). Sitting in a relaxed position, with the back and the arms properly supported, and the legs rested horizontally on the ground, can avoid RSI.
