Planning to buy a laptop? If you are not a techie person, and you happen to ask any geek for some advice, they will start belting you with technical terms and specs, which will leave your head reeling. Get a basic idea of the various features of a laptop before you begin shopping for one in earnest.
Laptops are available in a range of sizes from 14 to 21 inches,with 15.4 inches being the most common. This measurement refers to the diagonal distance of the screen. The screen size you choose depends on your needs and comfort level.
When it comes to screen, the next feature that you’ll probably hear about is the aspect ratio. It is a proportion between the height and width of the screen. There are two types of aspect ratios – standard and widescreen. These days, standard screens are being replaced by widescreen-format screens.
Resolution is described by the number of pixels across by the number of pixels down the screen. For example, when you check out a laptop, it says that the screen resolution is 1024 × 768, it means the height has 768 pixels and the width has 1024 pixels. A higher screen resolution means better image clarity. The screen’s clarity closely depends on its size, aspect ratio and resolution.
Another techie term that you would come across is RAM Memory. In simple words, RAM (Random Access Memory) is a temporary storage space. Everything that you save on your system is first stored in the RAM before it’s moved to the permanent memory. The higher the RAM, the faster your system will work. There are different types of RAM memory – DDR, DDR2 and DDR3.
The processor is the “brain” of the system, and determines the laptop’s performance. Two popular core processors in the market are AMD and Intel. The higher the number of cores in the processor, the higher performance it offers. Clock speed, measured in GHz, is another feature that tells you about the performance level of the core processor. It clocks the time that your processor can move from one task to another.
All your files, documents, videos and more are stored in the hard drive (HDD). A larger hard drive could mean higher memory capacity, but it also means that your laptop becomes heavier. On an average, most HDDs run at 5,400 rpm (revolutions per minute) while the higher end models may run at 7,200rpm. This number determines the data streaming speed.
