BUYING LAPTOP

A laptop computer needed to be was smaller and more portable than the desktop version These days the range on offer can be shaped and adapted to fit a number of different uses Configurable product choices of the type instigated by companies like Dell and Sony mean that you can mix and match components to fit your exact needs and get all that you need for a price that you can afford Laptop Processors Central processing unit CPU is sometimes described as the most important chip in the computer It contains the arithmetic and logic unit ALU so the computer can do calculations and the control unit that controls the flow of data between the ALU and memory Theres a lot of competition between manufacturers of processors and the speeds they offer but the plain fact is that while it is heavily featured in the marketing literature even the slower processors are fast enough for most uses even though 3 0GHz is offered on many laptops Money saved on processors might more usefully be spent on memory There are two things that really matter with laptop processors The balance struck between processor power and battery consumption and the links to mobile technology that enable you to make the most of the laptops portability For the first simply put processors with the word mobile in their name are going to be the best choice as in Mobile Intel Pentium 4 or Athlon XP Mobile These use less power and run cooler For the second Intels combination of processor chipset and wireless card technologies marketed under the brand name Centrino is hard to beat. Buying a laptop may be a new endeavor for you, or you may be replacing an older model. Either way, there are a few things to consider about your new purchase. Buying a laptop computer can represent a big investment. By assessing your needs, you can make a more calculated choice about what type of laptop to purchase. This can save you money and potential problems.

The first question to ask yourself is if you truly need to be buying a laptop. Laptops tend to lag behind desktops in terms of upgradeability and features. If you handle heavy graphics, do a great deal of video editing, or you are a gamer, a laptop might not be the best choice for you. In addition to having to spend a lot of money to get the system you need, you will also be unable to upgrade that system when the time comes. However, if you are highly mobile, a laptop is a good choice. acer computers,acer laptop,best computer,best laptopsbuy desktop computer,cheap computers,cheap new laptops,cheap notebooks,computer accessories,computer monitor,discount laptops,laptop computers,laptop deals,notebook computers,notebook reviews The second step is to look at what you require from your laptop computer. Students, for example, probably need Internet access and word processing capability. A laptop for business may need similar features, as well as the ability to handle databasing software. Assess your individual needs with care when buying a laptop. If you travel frequently, or carry a lot of heavy belongings already, you will want to look into buying a laptop which is very lightweight. If you travel less frequently, or have fewer concerns about heavy luggage, a larger laptop with more power and an easier to read large screen is a good choice.

Laptops tend to be more expensive than desktop equivalents. Do not buy a laptop which exceeds your needs. Make sure that the laptop features will meet expectations, without the need for expensive upgrades. Make an honest estimate of what you require, and seek out systems that will match your requirements. Often companies offer packaged deals, making it cheaper to buy a preconfigured laptop. Determine what features you need when buying a laptop. A ready availability of ports, is very useful. Many devices are designed to connect to Universal Serial Bus (USB) ports, so you may want several to connect multiple peripheral devices. If you have devices which use FireWire or other connections, make sure that your laptop will support them. A space for PC cards is also a good idea, as is an internal modem, wireless card, or ethernet port. Make sure that your laptop has headphone jacks so that you can quietly listen to music. In addition, you may want to consider a CD or DVD ROM drive. Software comes on CDs, data can be backed up onto CDs, and you can also listen to music or watch DVDs on your laptop computer.

When buying a laptop, it is important to think about what operating system you would prefer to use. Apples tend to be more expensive, overall, than PCs, but you may want to go that route if you interact frequently with an Apple network or use Apple programs. Especially if you are a student, look into what kind of software you need to succeed in school and which operating system it is designed for. Some schools also have promotional agreements with computer companies which can assist you in getting a good deal. Also look at what kind of software comes preloaded on the system, to see if it will meet your needs or if an additional outlay of cash is required to purchase software.Laptop RAM Random Access Memory RAM is where the computer stores applications that are running and data Most laptops come with a standard 256MB of Random Access Memory Moving up to 512 MB installed RAM is a must if you are intending to use the laptop for digital video or downloading music Even if you are not buying as much RAM as you can afford is one area of expenditure on computers that will always pay you back in the future Check out the RAM capacity to see how much room you have for future upgrades

Laptop Hard drives

The computer uses the hard drive to store programs and files The storage capacity of a basic 20GB hard drive is more than enough for most users However if you want to work with databases or digital photos and video files then moving to a bigger hard drive say 40 or 60GB may be worthwhile Some laptops are equipped with 120GB hard drives

Optical drives

CDRW is better because not only can you read CDs you can also write and record data to them Depending on the CD format you can record once R or multiple times RW Best if you want to copy music from your CDs into your notebook DVDROM can read DVD discs as well as CDs Best if you want to watch DVD movies on your laptop and install software from DVD or CD

Laptop Screen sizes The liquid crystal display LCD screens used in laptops come in a range of sizes from 12 to 17 measured diagonally Smaller screens mean lighter and more portable laptops but a 15 screen is common If you are going to be working on the machine a lot then a bigger screen with a decent resolution say 1024 768 will be better for you in the long run Higher resolutions mean you can fit more in on the screen but you may find it harder to read TFT thin film transistor screens are designed to perform better in bright light or sunlight and can produce clearer images Batteries Most laptops use are Lithium Ion batteries Battery life varies between laptops but somewhere between 2 and 5 hours depending upon the number of things that you are asking the laptop to perform would be about average Laptop battery recharging times will also vary around 75 minutes is common so buying a spare battery is well worth considering . Touch sensitive mouse pads This replaces the mouse on most laptops Some users find that initially this can be difficult to operate It is well worth testing out before you buy if you can. USB ports Many laptops come with more than one USB port which makes connecting to peripherals a lot simpler Newer models are also available with a Fire wire connection to transfer digital information from camcorders or MP3 players .Wireless LAN card You will need one of these if your laptop does not have builtin mobile technology It should fit into the PC Card slot of your laptop Printers Mobile or not at some time you are going to want to print The choices to make are between inkjet laser and allinones Antivirus software Vital if you are going to make any connection to the internet and you value your data and security Many laptops are sold with trial versions of products from major suppliers like McAfee or Symantec preinstalled Floppy disk drive Still around still working and floppy disk drives are still the cheapest storage solution for data around Investing in an external floppy disk drive means you can safely backup very small amounts of data from your laptop and still make use those old floppies you have hanging around Memory sticks Memory Sticks are an easy way to transfer small amounts data from your laptop to a desktop They should not be treated as a means of permanent storage

Hard Drives

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

Computer Monitor

Computer Monitor

Computer monitors have many features and come in different varities like flat monitors.etc.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 Most of the time all monitors is compatible with your personal computer or laptop As always check your personal computers manufacturer specifications to be sure that the monitor you are shopping for is right for you
