Facts ! You should know before buying a laptop | 9technoadda

Technology? It keeps the whole universe in our hands, we all are deeply familiar with laptops. Here you will get a full guide on what should we keep in mind during buying a laptop. There are thousands of laptops available in the market of different brands like Apple, HP, Dell, Lenovo, Acer, etc. So we get a little bit confused about which is the best laptop suitable for us. We decide it according to our requirements and budget. But before selecting any laptop it's our responsibility to keep a deep look in its processor, ram, graphics card, screen resolution, and sizes, etc. So before wasting much time let's get started.

laptop performance is mainly based on seven deep factors. We will discuss each factor in detail. 

1. CPU 

2. Ram

3. Graphics card   

4. Hard Drive (internal storage) 

5. Screen

6. Battery 

7. Operating system 

1.CPU. (Processor)

           One of the most important and essential topics to discuss. CPU is the brain of the computer. And the best laptop needs the best brain. It decides all processes that a laptop performing. 

The processor is mainly developed by two companies. 

• INTEL
• AMD

Intel provides the best processor for laptops. It covers almost 80% of the total laptop market. It launched a lot of processor upgrades like QUARK, INTANIUM, CELERON, PENTIUM, ATOM & CORE in a respective sequence. In the Modern era most widely & commonly using processor is Intel Core. A lot of series are also available with Intel Core processor .like Core-vPro, Core-M3, Core-i3, Core-i5, Core -i7, Core-i9, Core-X. Each core series are also developed continuously in different generations like 1st-generation, 2nd-generation, 3rd-Generation, etc. If you need a nice performance laptop you can select at least core i5 & if you are looking for i3 then always go with the 7th or 8th generation of core-i3. It will provide you up to 4.60 GHz Max clock speed and comes with six Core. It also provides up to 8 - 9 MB cache storage. 

FULL CHART ABOUT CORE PROCESSOR.

PROCESSOR	CLOCK SPEED	CORES	CACHE MEMORY
CORE-M3	2.00 - 3.40 GHz.	2	4mb
CORE-I3	3.40 - 4.60 GHz.	2-4	3-8mb
CORE-I5	2.70 - 4.60 GHz.	4-6	2-9mb
CORE-I7	3.00 - 5.00 GHz.	2-8	2-12mb
CORE-I9	4.40 - 5.00 GHz.	6-8	12-16mb
CORE-X	4.20 - 4.40 GHz.	6-18	8.25-24.75mb

(Clock speed, cores & cache memory depends upon which generation processor you are looking for)

PROCESSOR	PERFORMANCE
CORE-I3 (7th or 8th generation)	Best for daily use, Nice photo editing, Nice video editing, Nice performance with ASPHALT, GTA, PRINCE OF PERSIA, MOST WANTED, FREE FIRE, etc.  Normal performance with some high graphics games like PUBG, CALL OF DUTY, etc.
CORE-I5	Heavy photo editing, Heavy video editing, Smooth performance with almost all games like ASPHALT, PUBG, CALL OF DUTY, etc.
CORE-I7 CORE-I9 CORE-X	Extra advanced photo editing, Ultra unique video editing, Amazing performance with all games, YOU’ll never going to have any problem with any work you are performing with these processors but it would cost a little bit high.

                            

2. RAM (Random access memory)

We can also say it Rapid access memory too. It allows you to perform multitask on your laptop. It saves your running data location lines in bits and allows them to run in the background. if you started a new task on the home screen. The more ram you have the more task you can perform simultaneously. Today most common RAM provided by the company is  

DDR4 - 4gb. But the more RAM your laptop has, the better it is. You'll also get a dedicated slot to increase your RAM in the future according to your requirements. 

Nowadays most laptop comes with DDR4 Ram. (ddr4-double data rate 4). It is developed by J.E.D.E.C solid-state Technology Association. There are 3 series of Ram:-

a. DDR3 

b. DDR4 

c. DDR5 

RAM	PERFORMANCE
DDR3	LOW PERFORMANCE, HIGH BATTERY CONSUMPTION, LESS USED NOW.
DDR4	HIGH PERFORMANCE, LOW BATTERY CONSUMPTION, USED IN MOST LAPTOP NOW.
DDR5	EXTRA ENHANCED PERFORMANCE, LOW BATTERY CONSUMPTION, USED IN PREMIUM LAPTOPS.

3. Graphics card.

You can also say it display card, Video card, Graphics adaptor, etc. It controls the visual effect of your laptop. It makes everything enhanced what your laptop screen is displaying. There are basically two companies that produce graphics cards. 

a. RADEON

b. AMD 

Although Intel also provides its integrated graphics card on some laptops it's not enough if you performing some high-level process.  you need at least 2 GB integrated graphics card of RADEON OR AMD companies for the best performance of your laptop. Because? With a laptop, it may be! You ll not get any dedicated slot to increase your graphics in the future. For confirmation, Always make sure Does it have? So always go with a minimum of 2GB graphics card 

4. Hard disk

It is the primary storage inside your laptop. It contains all your installed software, operating systems, documents, and all other files.  It works as the internal capacity of your computer or laptop. Nowadays many laptops come with 500gb of total internal storage. But if you need the best performance I recommend going with at least 1tb (1024gb) of total internal storage. It depends upon your work and how much data you need to save in your HDD.

It comes of three types:-

a. HDD (hard disk drive)
b. SSD (solid-state drive)
c. SSHD (solid-state hybrid drive)

HDD	Hard disk drive	500gb – 50tb
SSD	Solid-state drive	60tb – 100tb
SSHD	Solid-state hybrid drive	Hdd+Ssd (dual drive Hybrid system)

5. Screen

If you are choosing the best laptop then you will have to choose the best screen. It is the most important component of your laptop. We have to check two things in the case of a screen. 1st size & 2nd resolution. The size of an ideal laptop screen is 14+ to 15+ inches. Let's talk about resolution, Screen is a combination of a series of unlimited cubes, Those cubes are called a pixel. The more pixel your screen contains the more enhanced visual you will get. The normal laptop comes with low resolution 1366 * 768. But an ideal laptop has an HD screen of 1920 * 1080 pixel resolution.

let's get through it 

SCREEN RESOLUTION	PERFORMANCE
1366*768	Mobile HD
1600*900	HD
1920*1080	Full HD
2560*1440	(2K) QHD
3000*2000	Pixelsense (MS-only)
3200*1800	(3K) QHD+
3840*2160	(4K) UHD-ultra high definition

We need at least 1920 * 1080 pixels of a screen on our laptop. 

6. Battery

Batteries are the heart of your laptop, absolutely your laptop is just a blank box without a power supply. we need a powerful battery to run our laptop in the case charging is not available. 
There are three types of batteries commonly used in our laptop 

a. Backup batteries:-  Backup batteries are used to backup your computer setting like date and time. 
b. Bridge batteries:- Bridge battery is working as the backup supplier for the main battery in the case if your main battery damaged, it indicates you to remove the damaged main battery. 
c. Main batteries:-  Main battery is the main source of energy for your laptop. The power of an ideal laptop battery is 41-watt hour. 

There are 4 types of main batteries are available in the market.

BATTERY TYPE	SELF-DISCHARGE RATE
Li-ion	2-5% per month
Li-polymer	8-12% per month
Nickel-cadmium	10-15% per month
Nickel-metal-hybrid	0.08-2.9% per month

(Nowadays most effectively and commonly used batteries are Li-ion & battery power must be 40-41 watt at least)

7. Operating system 

 
An operating system is system software that manages all the computer hardware and software's workup. Nowadays approximately 85% of the market is working with the Microsoft Windows operating system. Microsoft brings a lot of Windows upgrade from time to time and a lot of more functionality too. The most recently launched Windows upgrade is Windows 10. Its operation mode, optimizing a process, system security authentication is really amazing. Always go with Windows 10 operating system for your laptop.

List of all windows operating system series:-

>Windows 3X (1990)
>Windows 9X (1995)
>Windows NT (2000)
>Windows XP (2003)
>Windows VISTA (2006)
>Windows 7 (2009)
>Windows 8 (2012)
>Windows 10 (2014)
