How To Choose a Good Laptop | Top things to consider before buying a laptop

- No comments


How to choose a good laptop is big question for all users. Also some of our friends may seek our help to suggest a good laptop. In such case we can suggest them good laptop by considering some of factors. Here we are going to analyse things and factors that must be considered while buying a laptop. Depending on user computing needs, there are several factors to consider before deciding which laptop is best suited for  a user.

Performance

Performance should be one of your key criterion when looking for a laptop. The key is to match your computing needs with the kind of the power you’re looking for. Performance depends on following factors.

  1. Processor
  2. RAM
  3. Storage Type
  4. GRAPHICS
lets analyse each this factors :

Processor

A processor (CPU) is the logic circuitry that responds to and processes the basic instructions that drive a computer. The CPU is seen as the main and most crucial integrated circuitry (IC) chip in a computer, as it is responsible for interpreting most of computers commands












 


The low end processors (intel: atom, celron, pendium )offer basic level performance such as web browsing, video viewing, emailing and basics apps

Generations of Processors 

The generation of the processor is the first number after i9, i7, i5, or i3. Here are some examples: Intel® Core™ Processor i7-10710U Processor is 10th generation because the number 10 is listed after i7. Intel® Core™ Processor i9-9900 Processor is 9th generation because the number 9 is listed after i9.

The Latest generation always offer  better performance while consuming less power for battery life. So look latest generation for better perfomance 


RAM

The amount of RAM decides on how smooth and lag-free an experience you get on your laptop. The higher the amount of RAM the better it is. However, here’s an indication of what you can expect from laptops with varied RAM configurations








These days, you’ll probably want to think about 8GB as a minimum. If you’re a power-user, 16GB is the way to go. Meanwhile, gamers should look at dialing things upwards all the way to 32GB if they want the best experience.

More RAM allows for more applications to be run at the same time, and for more data to be quickly accessible by the system at any one time, which comes in handy for tasks such as editing photos or video content.


GRAPHICS

Graphics card of computer is generally two types such as integrated and dedicated. Integrated card is called the built-in card. This card is suitable for everyday use. With this graphics card, you can browse the internet, watch YouTube, etc. easily. But complex works are slow in this card.
The dedicated graphics card has advanced technology. You can do hard tasks such as video and photo editing without any trouble on a laptop with a dedicated type graphics card. So, for better performance, you should choose the computer with dedicated graphics.

Choosing ideal Graphics Card

Usage Required Graphics
Everyday use: browsing the web and multimedia Integrated graphics
Gaming and image editing Dedicated 1 GB
Advanced gaming experience or video editing Dedicated 2 GB
Professional gaming, animation, 3D rendering Dedicated 2GB and above


Choosing ideal Graphics Card

Gaming Laptop Type Graphics Processor Performance
High end gaming laptops Nvidia GeForce GTX 1060, 1070, 1080 Smooth 60FPS gaming at high and ultra settings on latest games
Premium gaming laptops Nvidia GeForce GTX 1050, 1050 TI Fluid 30FPS gaming at high settings on latest games
Entry level gaming laptop Nvidia GeForce MX150, 940M & AMD Radeon R7 M44 GeForce 960M 950M 30 FPS gaming at medium and ow settings




Storage

Hard drives used to be all the rage, but these days they’ve mostly out of favour, especially for thin and light laptops. This is because they can be slow, somewhat bulky, and produce noticeable heat and noise.

A solid state drive (SSD), on the other hand, offers a lot more speed than a hard drive, runs silently, and can be installed in a form factor that doesn’t add too much to the weight and bulk of a laptop. As a result of these clear benefits, most OEMs have embraced SSD storage as the standard for laptops.

Storage types

  1. HDD-Hard Disc Drive
  2. SSD-Solid State Drive

SSD vs HDD: Which One Should You Get? (5 Aspects Compared)

HDD VS SSD

Display

When it comes to laptop displays, the display size and resolution are the key factors that one needs to consider.

Resolution

Higher resolution will make text and images more sharper and plesent to the eye.
HD Full HD 4K
Offers 1280 x 720 pixels Offers 1920 x 1080 pixels Offers 3840 x 2160 pixels
Found in entry-level laptops Found in premium and gaming laptops Found in high-end laptops
Good for basic tasks Good for entertainment and productivity apps Consider it if you watch a lot of 4K content


Display

13.3 INC 14 INC 15.6 INC
If you plan to travel frequently Perfect balance between screen size and portability Entertainment-oriented Laptop
When looking for a lightweight laptop Mixed usage of office applications as well as entertainment Portability is not too important for you
Primarily use the laptop for office applications Optimal performance and storage space More USB ports and an optical drive

Operating System

An operating system manages the hardware and software resources of a computer, while also providing common services that are essential to all software on the system.operating system
 
Mac OS
  • Great user interface
  • Applications run without lag
  • UNIX-based code makes the OS more secure
  • Apps are malware and virus-free as they are curated by Apple; limited choice of apps
Windows OS
  • Most popular
  • Compatible with most hardware and software
  • Supports third-party programs
  • User interface can be customized
  • Easy to multitask using multiple windows
  • Try apps and software before buying them
  • Share data across all synced, compatible device
  • Enhance, edit and organise photos
  • Access systems using virtual desktop
  • Features Cortana, the personal assistant with voice recognition

UBUNTU & DOS

Laptops that ship with Linux-based, open-source, operating systems or DOS operating systems are suitable for programmers and coders. Ubuntu is the most popular Linux-based operating system that has an appealing graphical user interface. Laptops that come with Ubuntu can be used for basic applications like web browsing and media consumption.

Chrome OS

  • Available only on Chromebooks
  • Apps can be added through the Chrome Store
  • Web-based
  • Mostly free applications
  • Google has announced Google Play Store will be added to all Chromebooks by 2016
  • Features Google’s built-in malware and virus protection

Other Features

Keyboard quality

For long typing sessions, you’ll need to get a laptop that has a comfortable keyboard. You want a keyboard that has a comfortable layout with full-sized keys and some space around the arrow keys. Make sure the keyboard is also backlit, so that you can type with an easier view on the keys in dimly lit environments.

Touch screen

Touchscreens make computer interfaces simpler. Just as you would on a smartphone, you can tap to select, hold and drag to move items, swipe to scroll and pinch to zoom.

Battery life

Manufacturer-quoted battery life is almost never indicative of what the real-world experience of using a laptop is like. There are simply too many variables that affect battery life. The operating system a laptop runs on can also play a major role in determining battery life. It’s for this reason that ultrabooks and convertibles running on Chrome OS tend to offer superior battery life than those running on Windows 10. A good practice here is to look at the rating of the battery in Watt-hours or milliamp-hours . The larger these figures are, the longer the battery can last.

Fast charging

Useful feature when you need to charge your laptop in the least amount of time.

Black-light keyboard

Makes typing easy when using the laptop in low-light environments.

Ultra slim bezel display

Provides a larger screen in a smaller form factor. It looks good as well.

USB 3.0

These days, if a laptop has less than one USB 3.0 port on it, you probably ought to look at buying another laptop. Ideally, you should look for a laptop that has at least a couple of these USB 3.0 ports. If possible, you should try and take things a step further and go for a laptop with USB 3.1 ports.

USB type-c ports

Latest connectivity makes for fast data transfers with external storage devices.

Fingerprint reader

Fingerprint-based login is useful when laptop access and security is a concern.

Infrared Camera

Windows 10 laptop users can open the computer by looking closely at the screen. You can use this feature if your laptop has an infrared camera or a RealSense 3D camera.

2 in 1 PCs

You can enjoy laptop browsing on your bed or at the table with this type of laptop. You will find detachable screen laptop or a rotate screen laptop common and available in the market.

Top 10 Frameworks and Libraries For Mobile Application Developers 2020

- No comments


1. Flutter

This is an excellent framework for developing cross-platform native mobile applications in 2020. Like GolangTensorFlow, and Angular, Flutter is also from Google, which uses Dart (another programming language from Google) and provides SDK for developing a cross-platform native mobile application.

It’s always been challenging to release your app to different platforms like 
AndroidiOS, and Windows Mobile, as you need to maintain separate codebase. Flutter solves that problem by allowing you to create mobile apps for both iOS and Android devices using the same codebase.

Flutter has seen a lot of growth in the last 2 years, and its now the #1 framework for developing native mobile apps

 Flutter for Cross-Platform app Development: to use or not to use ...

2. React Native

Apart from Flutter, if there is another framework you can check out for developing native cross-platform mobile apps, then they React Native. It uses React and JavaScript for producing high quality native mobile apps.

It’s the right choice for all web developers who wants to become a mobile app developer and already familiar with technologies like 
JavaScript and React. If you are one of them, then I suggest you learn React Native in 2020.

React Native Tutorial

 

3. Kotlin

Kotlin is a general-purpose programming language from JetBrains, the company behind tools like IntelliJIDEA, Reshaper, and PyCharm. If you don’t know, Kotlin is the official programming language for developing Android applications as announced by Google a couple of years ago.

It’s a beautiful, JVM based programming language and compatible with Java, another popular language for developing Android applications.

If you are serious about developing mobile apps for the Android platform, the world’s most popular mobile platform, then you should learn Kotlin.

5. Native Script

If somehow you didn’t like React Native and Flutter and looking for alternatives, then you can also check out Native Script. NativeScript is a free and open-source framework to develop a mobile application for both Apple iOS and Google’s Android platform.

It allows you to build native mobile apps in both 
TypeScript and JavaScript and using Angular and Vuejs. If you are a frontend developer and already know frameworks like Angular or Vuejs, then Native Script can be the right choice for you.

NativeScript features deep integration with both Angular and Vuejs and allows you to write code on any language, which translates into JAvaScript like TypeScript or CoffeeScript.

 Native mobile apps with Angular, Vue.js, TypeScript, JavaScript ...

6. Android 10

This is the latest version of the Android platform. It was released on September 3, 2019, and unlike the previous Android version, it doesn’t have any sweet name like KitKat, Oreo, or Lollipop.

If you are interested in the Android platform or already an Android developer, you can learn Android 10 to learn new features like Dark Themes, Smart Reply, Gesture navigation, 5G Networks, Enhanced location, and privacy tools, etc.

You can also optimize your apps for foldable and other large-screen devices. If you are an Android developer or want to learn Android in 2020.

7. iOS 13

This is the latest release of the popular iOS platform, which powers the iPhone and iPad, two of the most powerful devices of humankind. I just updated my iPhone on iOS 13, and I am really impressed with sleek writing without lifting my finger.

It also comes with some exciting features developers have long been asking. For example, with the iOS 13 SDK, your app can take advantage of Dark Mode, Sign In with Apple, Core Data syncing with CloudKit, PencilKit, and more.

Weekly poll: is iOS 13 a worthwhile update for the iPhone? What ...

8. Ionic

This is another framework for developing hybrid mobile applications using JavaScript. Ionic also allows you to build cross-platform mobile apps, which means you can create an application for any platform using one codebase.

Ionic Framework is a free and open-source and provides a portable UI toolkit for developing high-quality cross-platforms apps for native 
iOSAndroid, and the web- all from the single codebase. It also has an Ionic React that leverages React for building hybrid mobile apps.
