What are the specifications of a good laptop?
What things should we keep in mind while buying a laptop and what is the meaning of the terms related to it, we are all going to know in this article.
The performance of any laptop mainly depends on these 5 things:
The performance of any laptop mainly depends on these 5 things:
- Processor
- Memory
- Operating System
- Graphics
- Battery
Performance = Processor + Memory + Operating System + Graphics + Battery
1. Processor
A processor is a type of chip that is installed in computers, mobile laptop tablets etc. and is a major part of all these gadgets. It understands the movements between hardware and software. The processor understands every activity that happens between us and the computer, only then can the computer understand our given command and work on it. And until the computer does not understand the command given to us, we cannot work on the computer.
Laptops with Intel's following processors are available in the market today:
Processor performance
Core i7 > Core i5 > Core i3 > Pentium > Celeron > Atom
The performance of the Core i7 is the fastest and the lowest of the Atom.
Processor performance in Laptop world is usually estimated from the core. the more core in the PC/Laptop processor , better the performance is likely to be.
Atom processor
It is the most basic processor. The clock speed of this processor can be from 1.3 GHz to 1.6 GHz, remember - the higher the clock speed the processor will be. This processor is often used in tablets or notebooks. With a laptop based on these processors, you can play movies, etc. and a little bit of internet. Laptops with Atom processors run very slowly and run hangs when running software like AMS Office.

2. Memory
Memory is the electronic holding place for the instructions and data a computer needs to reach quickly. It's where information is stored for immediate use. Memory is one of the basic functions of a computer, because without it, a computer would not be able to function properly. Memory is also used by a computer's operating system, hardware and software.
There are technically two types of computer memory:
- Primary Memory / Main Memory
- Secondary Memory / Mass Storage
1. Primary Memory / Main Memory
Primary memory is known as “Main Memory” or “Internal Memory” or “Primary Storage Device” or “Internal Storage Device” as well as they play vital role in computer, because those memories are capable to access all data directly from CPU with the help of various buses. These memories have limited capacity for storage and made by integrated circuits (IC) or semiconductor components.
In other words, Primary memory is the computer memory that is directly accessible by CPU. It is comprised of DRAM and provides the actual working space to the processor. It holds the data and instructions that the processor is currently working on.
The most important things is Primary memory is temporary.
Examples are : RAM, ROM, Cache memory, PROM, EPROM, Registers, etc.
There are two types of primary memory :
- RAM (Volatile)
- ROM (Non-volatile)
1. RAM (Random Access Memory)
RAM means Random Access Memory. Most of the data of any application, files etc. you open while using a laptop is stored in RAM. The higher the RAM of a laptop, the more apps you will be able to use simultaneously. The more RAM in the laptop, the better will be its performance.

What is the type of RAM?
Nowadays there are 2 types of RAM available in the market:
Nowadays there are 2 types of RAM available in the market:
- DDR3
- DDR4
DDR3: It's a bit slower and consume more power
DDR4: it's faster and consume less power
Simply put, in terms of performance, DDR4 is better than DDR3
Nowadays the laptop with 2GB, 4 GB, 8 GB, 16 GB RAM is available in the market.
DDR4: it's faster and consume less power
Simply put, in terms of performance, DDR4 is better than DDR3
Nowadays the laptop with 2GB, 4 GB, 8 GB, 16 GB RAM is available in the market.
2. ROM
ROM is primary memory and ROM stands for “Read Only Memory”. This memory is able to store data in permanently means to have non-volatile in nature, i.e. the data remains even in the event of a power failure. Access to all memory cells takes the same time (unlike with hard drives), which is why OS data is usually stored inside ROM memories to ensure a quick boot and to prevent changes by users. However, the ROM content may be altered in special cases.

However, the ROM content may be altered in special cases.
DVDs or CDs are an example of ROM memories that cannot be updated, whilst a console has a ROM memory that can be updated.
Generally, there are three types of ROM :
- PROM
- EPROM
- EEPROM
What is the difference between Volatile and Non Volatile memory ?
Volatile memory requires a constant source of power to maintain its contents whereas non-volatile memory does not require a constant source of power to maintain its contents.
Volatile memory requires a constant source of power to maintain its contents whereas non-volatile memory does not require a constant source of power to maintain its contents.
2. Secondary Memory
Secondary Memory is also called “storage device” and “auxiliary memory“, “external memory“. Secondary storage devices are volatile in nature, it means that data does not discard while power turn-off, in which all data store for long time. Secondary memory has the speed of access of data is very slow compare to primary memory, and cheaper as well. Without primary memory, those secondary storage devices are useless because for processing the secondary memory must be needed the primary memory, first of all data are transferred into primary memory then these data make for executable.
There are three types of internal storage according to speed:
- HDD (hard disk drive)
- SSHD (Solid-State Hybrid Drive)
- SSD (Solid State Drive)
SSD (Solid State Drive) is the fastest if you talk about speed but it is very costly and HDD (Hard Disk Drive) is the slowest among the three. But it is cheaper.
SSD > SSHD > SSD
In laptops that use SSD, Windows (or operating system) is loaded within 5 seconds. According to the capacity, HDD is available in 500 GB, 1 TB and more than 1 TB in size.
Apart from the operating system, you can store a lot of software and movies in a hard disk ranging from 500 GB to 1 TB capacities.
Memory vs. storage
The concept of memory and storage can be easily conflated as the same concept; however, there are some distinct and important differences. Put succinctly, memory is primary memory, while storage is secondary memory. Memory refers to the location of short-term data, while storage refers to the location of data stored on a long-term basis.
3. Operating System
The operating system is a group of software that controls the transmission of data and instructions. It acts as a bridge between hardware and software and is a software component of a computer. The operating system is the backbone of a computer, which keeps its software and hardware under control.

Laptop Screen
Many people choose the laptop from the screen size, but never choose the laptop from the screen size. One, the size of the laptop can be heavy due to the large screen size. Also, if the display is low resolution then computing experience can also be bad.
Many people choose the laptop from the screen size, but never choose the laptop from the screen size. One, the size of the laptop can be heavy due to the large screen size. Also, if the display is low resolution then computing experience can also be bad.
Therefore, prefer only the screen with good resolution.
Resolution
Resolution is a mathematical calculation that measures the number of pixels in a digital image or device display.
Device Resolution:
How many pixels a device is capable of showing horizontal and vertical is the resolution of that device
It is called. The device resolution is mainly mobile screen, television screen, computer monitor screen Used for.
Display resolution = width x height
(Width is the number of horizontal pixels)
(Height is the number of vertical pixels)
For example :
Resolution of an HDTV is 1920 x 1080
(1920 is the number of horizontal pixels)
(1080 is the number of vertical pixels)
Resolution of an HDTV is 1920 x 1080
(1920 is the number of horizontal pixels)
(1080 is the number of vertical pixels)
These are some of the device resolutions which are more popular in the market :
- 720p = 1280 x 720 - It is also called HD or "HD Ready" resolution.
- 1080p = 1920 x 1080 - FHD or “Full HD” resolution.
- 1440p = 2560 x 1440 - This is called QHD or Quad HD resolution,
- 4K or 2160p = 3840 x 2160 - Typically 4K, UHD or Ultra HD resolution.
Yes, take screen LED only. 11 inch screen size is good for less users. A 14-inch screen is suitable for use at medium levels. It also does not make weight too much nor does it look too big. For heavy use, you can take a 15-17 inch laptop.
Which is a better laptop?
It would not be right to call a laptop of any kind of configuration better. Different laptops are available in the market according to price and performance.
