Computer Monitor

The Advantages of LCD or Flat screen Monitor A special feature of our Consul LCD mounting arms is their inter changeable arm lengths their flexibility in reach with extension arms and variable height These mounts adapt to almost all applications involving more than one flatscreen monitor and they attach securely to any flat surface desktop or pole An electric current passed through the liquid causes the crystals to align so that light cannot pass through them Each crystal therefore is like a shutter either allowing light to pass through or blocking the light

LCD screen has no static not even to raise a hair on the back of a hand and the screen and the entire unit is only slightly warm hardly enough for convection currents Compare that to placing your hand over the back ducts on a CRT nearly enough to fry an egg

The main advantage of LCD displays is that they take up less desk space and are lighter

When the beam current of a CRT is increased to boost brightness the beam spot size also increases which lowers effective resolution and may yield a soft or fuzzy image

There is no flicker on an LCD display because while a CRT must be refreshed the LCD has a constant source of light over the whole screen Once a pixel is on it stays on until turned off

The power required to run an LCD is about onethird of that required for a CRT with the same screen area In addition the amount of heat generated by an LCD monitor is considerably less than a CRT monitor resulting in a lower load on air conditioning

LCD prices have been decreasing in recent years When the total cost of ownership is consideredincluding savings in power consumption and lifespanLCDs are now less expensive than many CRTs

An LCD is essentially emissionfree while a CRT monitor can generate electric magnetic and even Xray emissions due to the highvoltage power supply necessary to drive the CRT An LCD causes no electromagnetic interference

Computer Monitor comes in a range of different prices You can find some forms of cheap computer monitors from as little as Rs 5600 to over Rs 160000 Price ranges for computer monitors general depend on the manufacturers and whether it is a standard monitor flatscreen monitor or LCD monitor There are many quality manufacturers of computer monitors like View sonic NEC Samsung Proview Dell or CTX and many more.

Hard Drives

Hard drives are the storage medium in desktop and laptop computers as well as all servers and mainframes throughout the world A hard drive is a piece of hardware that reads and writes data on a hard disk Hard disk drives for personal computers generally have seek times of about 12 milliseconds or less Many hard drives improve their performance through a technique called caching There are several interface standards for passing data between a hard drive and a computer The most common are IDE and SCSI Although removable disks encased in cartridges use the same hard disk media and a similar drive technology they are mostly called removable drives rather than hard drives. IDE Integrated Drive Electronics a hardware interface widely used to connect hard disks optical disks and tape drives to a PC Introduced in 1986 with 20MB of storage capacities increased a thousand fold in less than two decades Compared to the SCSI interface IDE has been the more economical choice IDE is a standard electronic interface used between a computer motherboards data paths or bus and the personal computers hard drive

SCSI was developed as an industrywide standard It is used on PC Servers and was used on Macintosh but it was also designed to handle the heavy load of performance critical central servers that cost hundreds of thousands of dollars It is better than ATA but more expensive SCSI is a parallel interface standard used by motherboards data paths or bus and the personal computers hard drive SCSI interfaces provide for faster data transmission rates up to 80 megabytes per second than standard serial and parallel ports which is why SCSI hard drives are generally more expensive than IDE hard drives

Hard Drives comes in a range of different prices You can find many discount in hard drives from as little as Rs 800 to over Rs 4 00000 Price ranges for hard drives general depend on the manufacturer and the amount of gigabytes offered with the hard drive There are many quality manufacturers of hard drives like Toshiba Western Digital Quantum Maxtor Seagate Maxtor Hatachi Fujitsu and many others A gigabyte derived from the SI prefix giga is a unit of information or computer storage equal to one billion that is a thousand million bytes One gigabyte is roughly equal to 18 hours of MP3 music at 128 kbit s One gigabyte is roughly equivalent to 11 hours 40 minutes of Flash video at 450x370 A gigabyte is a measure of computer data storage capacity and is roughly a billion bytes Todays hard drives are much less expensive than they have ever have been Buying a 100 GB is very affordable today but as earlier as 6 years ago it was unheard of ..In internal hard drive or external hard drive no matter the type of computer you have An internal hard drive must be properly installed within the housing of the computer To properly install an external hard drive your computer must connect with a 6pin or 4pin FireWire port to transfer the data between the motherboard

Memory which is commonly referred to as RAM Random Access Memory is a temporary Volatile storage area utilized by the CPU Before a program can be run the program is loaded into the memory which allows the CPU direct access to the program Memory is a necessity for any computer and it is recommended that you have at least 64MB of memory for your IBM or Macintosh .

Its always a good time to add RAM to your computer A memory upgrade is easy to install is relatively inexpensive and can improve the overall performance of your computer

And for missioncritical applications using highend servers you might need as much as a 512MB upgrade to achieve maximum uptime and productivity or even a 1GB upgrade depending upon your performance needs

If you are upgrading a laptop in most cases you can only upgrade the memory hard drive and modem The rest you have to live with If you cant live with it then consider replacing it with either a new laptop or a used laptop

A memory upgrade is particularly helpful for users who work with large files have more than one program open at one time or use memoryintensive applications such as games or graphics and video editing software Memory upgrades can dramatically speed up the overall performance of your home or business computer system
