What is Computer?

Now a day’s most of the people those who are using desktop computers are moving to Laptop. Laptops are more expensive than the desktop computer, so we have to choice the best Laptop while purchasing. So we people should have a knowledge about the Laptop, if we does not have the knowledge about Laptop we cannot choice the correct Laptops.

So let’s see what are the things to consider when purchasing a Laptop?

First of all we should decide the brand of the Laptop which we are going to purchase. To buy the best brand, choice any one of the brand from the below given brands.

SONY

HP

DELL

SAMSUNG

THOSHIBA

LENOVA

ACER

Then, from the selected Laptop brand we should consider the following things.

LAPTOP CONFIGURATION

Processor

Processor is a very important chip in the Laptop mother board. The best processor in the present market is Intel Core i7. After this Intel Core i5 and Intel Core i3 are next best processor. If you’re ready to purchase an expensive Laptop, first of all choice a best brand and then choice the one of the given below processor.

Intel Core i7

Intel Core i5

Intel Core i3

If you decide to purchase a cheaper Laptop than the above mentioned, then you can choice either one of the processor.

Intel Core 2 Duo

Intel Dual Core

If you select the lower quality processor than the above mentioned processors, it’s not suitable for the latest technology.

Next we should consider on Processor Speed. 1.60 GHz Speed and 2.0 GHz Speedprocessors are very slow. So choose 2.8 GHz speed or higher than this.

RAM

Next we should concentrate on RAM size. RAM size is responsible for computer speed, when we run more than 1 program at a time the computer will get slow. So if we want to run latest advanced programs, we should at least use 2GB RAM. If we have more than 2GB RAM your computer will have more speed.

Mostly latest laptop comes with DDR2 RAM, but DDR3 RAM is better than DDR2 RAM. 
So if you wish, you can replace DDR2 RAM to DDR3 RAM. 

HARD DISK

The Laptop which we are going to purchase should have at least a Hard-disk with capacity of 320GB. Because if we want to use the latest advanced software like Photoshop, CorelDraw we need at least 320GB Hard-disk. To save our data and files, we need this much of Hard-disk capacity. When selecting a Hard-disk, we must consider on Hard-disk Speed also.

The following Hard-disk Speeds are better to use in latest Laptop.
SPEED 7200RPM
SPEED 5400RPM

If your Hard-disk speed is less than above mention speed, select one of the Hard-disk from above mentioned.

DVD DRIVE

If you’re buying a branded Laptop you don’t want to care a lot about DVD drive. Because mostly branded Laptop comes with suitable DVD drive.

GRAPHIC CARD

When purchasing a Laptop the next important thing to consider is Graphic Card. It’s important because if you’re using Photoshop, CorelDraw, playing a video game or if you wish to watch HD Videos in your Laptop, you should have quality Graphic card. 


When you select a Graphic Card another important thing to consider is whether it is“Dedicated Graphic Card” or “Integrated Graphic Card”. 
“Dedicated Graphic Card” is much better than “Integrated Graphic Card”. If“Dedicated Graphic Card” is fixed in your Laptop, while playing high quality games the Laptop wont get slow.

OPERATING SYSTEM

Next select the Operating System for your Laptop. In the latest Laptops, mostly Windows 7installed as operating system. But Windows 7 has different versions.

Windows 7 Ultimate

Windows 7 Professional

Windows 7 Home premium

Windows 7 Home basic

Windows 7 Starter version

Select one of the above mentioned version. But 

“Windows 7 Ultimate” and 

“Windows 7 Professional” are the best, so choice either one of this.

Mostly latest laptop comes with Webcam, Mike but once again check whether these are available or not in laptop. And also check HDMI port, Memory card slot, Front mike, etc...
