Computer and internet are basic needs of modern world. Every person whether a student, businessman or serviceman needs a laptop or computer for professional work. Laptop is a portable computer which can be easily carried from one place to another. While purchasing laptop we must look for certain hardware and software components in laptop. Following article provides tips on What to see while purchasing laptop.
While purchasing laptop we must consider following things:
CPU is the most important component of a computer. The speed of CPU determines the overall
performance of laptop. CPUs are manufactured mainly by two companies named INTEL and AMD.
AMD CPUs are generally cheaper than their INTEL counterpart but INTEL CPUs are preferred to AMD due to better branding.
Most popular CPUs of Intel are i3, i5 and i7. Their differences are listed in following table:
|Processor/Features||Core i3||Core i5||Core i7|
|Number of Cores||2||4||4|
|Speed||3.4 GHz to 4.2 GHz||2.4GHz to 3.8 GHz||2.9 GHz to 4.2GHz|
|Cache Memory||3 to 4 MB||6 MB||8 MB|
One core means one inbuilt CPU. More the cores, more the performance. So we can see that Core i5 and i7 have more cores as compared to i3. So obviously they will perform better than i3.
Turbo Boost feature is another performance boosting feature. It is enabled for Core i5 and i7.
More the Cache memory, better the performance. Core i7 has the largest cache memory of 8 MB which is the largest among all. So Core i7 is the best as far as cache is concerned.
AMD’s Ryzen processors with the high-performance Threadripper series are very popular these days but they are mainly being liked by gamers.
Core i3 is good for low performance activities. It is good if you have to work with MS Office, simple softwares, listen songs, watch movies. It is good for small businessmen and students.
Core i5 is medium range CPU. It is good if you are a college student and medium businessman. You can use it for high end official tasks, programming , web designing and development and even for playing online games.
Core i7 is high end CPU. It is good if you need very high speed and performance by your Laptop. It is good if you are a graphic designer and gamer.
” Better the RAM, better the performance of a laptop”.
RAM is second most important component that determines the performance of a laptop. RAM is the memory
used for storing data and applications temporarily. RAM of 4 GB or more is good to get the best out of your laptop.
3. Screen Size
Screen size is also an important factor while purchasing a laptop. Bigger the screen size, lesser the strain on eyes. Screen size of laptop varies between 11.6 inches to 17.3 inches .
Most commonly used sizes are 14 inches and 15.3 inches. They are good for routine tasks and multimedia applications.
4. Screen Resolution
“More the screen resolution, better the quality of display”.
You must check the highest resolution supported while purchasing a laptop. Typical resolution starts from 800 X 600. These days resolution of 1366 X 768 or more is good to get proper display of web sites and software applications on the laptop screen.
Material of laptop is also an important factor while choosing a laptop. Some laptops are made of very hard material which are basically useful for rough and tough use and very harsh industrial environment.
6. Storage Device
Hard disk is the most important storage media. All laptops come equipped with hard disk. This is the most commonly used storage media for keeping operating system, softwares and user files permanently.
The speed of hard disk is measured as rpm (Rotations per minute). More the rpm, more the speed of hard disk for fetching and saving data on hard disk.
While purchasing laptop, size of hard disk must be checked. Minimum size of hard disk is 1 TB these days. Laptops having hard disks with more storage space are also available in the market.
These days SSD disk drives are also getting popular. They are faster than hard disks but you need to spend more money for them.
We must look at ports while purchasing laptop. All laptops come with different ports for attaching external devices to laptop. One of the most commonly used ports is USB 3.0.
Your laptop must have one or more such ports. They are needed to take backup of your laptop data to external hard disk fast and attaching USB devices like printer, mouse and external keyboard.
Other ports include, finger print reader, Fireport, Lan Card, Card Reader erc.
Battery is the life line of a laptop. Capacity of a battery is measure as Watt-hours (Wh) or milliamp-hours (mAh). Larger the mAH , longer the battery will last. For a 13.3 inch Ultrabook, a battery from 44Wh to 50Wh will give the best results.
Keyboard is very important component of a laptop used for typing the content. Keyboard should be comfortable and strong if you have to work on laptop for longer hours.
Very thin or very thick keyboards should be avoided as thin keyboard will not last long whereas you may find it tiring to press keys on thick keyboard.
This is the most important factor while purchasing laptop. The price of brand new laptop starts from Rs 15,000 and goes on depending upon different hardware components and screen size.
11. Operating System
Most of the laptops come with pre-installed operating system. This operating system may be LINUX, Windows or Macintosh. If you purchase a Macbook, you get pre-installed Macintosh in it.
You can also purchase laptops having latest version of Windows. Such laptops are generally more expensive than laptops having LINUX or DOS operating system.
