Hi there, in this article I'm going to explain a very useful topic related to software and its installation. In which, I will talk about "Portable software benefits over normal software | Portable software fully explained".

So, Welcome to "Postdynamic - The Master's World".

Before we start with benefits, it is necessary to explain to the basic difference between normal software and portable software.

So #LetsGoInDetail

Portable software benefits over normal software | Portable software fully explained

So the differences are given below
1. Normal Software
Normal software is software which is mostly in a setup package and requires installation. And during its installation, the installation directory is created in operating system drive i.e. the drive where the operating system installed.
And after installation of software you can not move it's files or software to another drive or location. Because doing this may result in either damage of software files or software will not work.
Therefore it will remain limited to use on that drive and system, where we install it.

As an example you have Google Chrome browser which is installed in C: drive. So you can not move it to other drive or location. If you do so, it will not work.
2. Portable Software

Portable software is software which do not require any installation to work. It may be present in the "zip" file or any compression format, which is easy to move from one place to another place. It can also be a directory containing all sub-directories and software files.
And it can run directly from any drive,folder and USB drive without any problem.

You can move it easily from existing drive to any drive.

Portable software benefits over Normal software

There are many "Portable software benefits over Normal software". Let's have quick look on main benefits.

  1. First and major benefit is Portable software don't require any installation.
  2. As it is portable, so you can easily carry it in you external drives like PEN drives.
  3. Private and personal data savior in some cases like :- Corrupt or damage Windows. Which requires new fresh installation of Windows that means it will delete all the software and data(which may be images, login username and passwords in browsers).
    But if you are using Portable software, which is in other drive than of Windows/Operating System drive. That means no issue for you and your data.
  4. You can run portable software where you have no authority to install any software without administrator permissions or privileges. This happens mostly in office computer systems. :-)
And more benefits you can enjoy with Portable software.

As we have discuss benefits, there are some "cons" also for Portable software.
  1. You need to update it manually.
  2. Portable software file size is larger than the Normal software, when you will download it.
  3. Every Normal software's portable software is not available.
Well these are not really considerable cons.
How can I get/download Portable software?
-Well it is true that every official website of a particular software, do not provide Portable software versions. Most of them only provide Normal software setup.
-But still you can download Portable software versions from some other third-party websites like open source project websites.
-All you need to do is just search like this "ABC portable". Where ABC is name of your software.

Finally, this the end of article "Portable software benefits over normal software installation | Portable software fully explained"

Hello there, this article help you purchasing new smartphone .

Competition between smartphone makers is increasing day by day.
So as a result marketing is also playing dark with tricks.
Means the item you are purchasing, is it really best according to its price?

Welcome to "Postdynamic - The Master's World" this is going to informative for you to read this article completely.

So #LetsGoInDetail

Let's Start with the topic Purchasing new smartphone carefully check this guide

First of all we need to know the things to focus on.
For which check the below list.
  1. Cost
  2. Features
  3. Technical Specifications
  4. Comparison
  5. Quality and Durability
  6. Service Support
  7. Brand


Main thing to concentrate before purchasing new smartphone is cost. Because everyone has the their own budget. Once you have decided money to spend on purchasing new smartphone. Now you have to move onto next step features that what features are available at this price.


Check for the features you can get at the budget you have made by searching for available smartphones. You can search on internet and local markets.
While checking features keep in mind that you have to look for maximum and latest features as your budget price. It depends upon you that you want basic features, moderate or advance features.
According to me, never go for basic features. Always look for either moderate or advance.

Minimum Features a smartphone must have are
  • Latest Version of Android or iOS.
  • 2GB RAM and recommended 3GB RAM.
  • 16GB Internal Memory and recommended 32GB.
  • 1.2Ghz processor(quad core) and recommended either 1.7 or 1.9 Ghz processor(octa core).
  • Dual Front camera and Back camera(with LED flash).
  • Proximity sensor.
  • Infrared
  • GPS.
  • 2G/3G/4G/5G network support.
  • WiFi, Bluetooth and NFC(optional).
  • Memory card support.
  • Dual SIM support.
  • Clean and easy GUI(Graphical User Interface)(comes in Operating system)

Technical Specifications

Technical specifications are in-depth of features to check the limitations.
For this we already have an article read this Difference between features specifications and technical specifications .


When purchasing new smartphone don't forget to compare with other brands of smartphones at either on same price or approximate price.
Compare all features and technical specifications carefully.
You note the features then compare after collection sufficient information from internet.

Quality and Durability

This is also the main factor to care about when purchasing new smartphone.
Do Check the quality of material used on its body frame(metallic is best avoid plastic body).
Must Check glass used for display and type of display (like gorilla glass with amoled display are better).
Look for the design(should look nice when holding in hand).
Check for durability of its battery by checking main factors. Like Li-ion Battery with xxxx mAh capacity(where x is any number from 0 to 9).
Go with the maximum battery capacity.

Service Support

When purchasing new smartphone do check for the service support.
Check that the smartphone of brand your are going to purchase, has "Service care center" near your location. And If not then you should not buy that brand's smartphone.
Because if anything goes wrong you have to suffer for it.


Because, there is a high competition between smartphone maker brands. Therefore Everyone trying to provide best.
Hence now a days Brand name is not a big factor now for purchasing new smartphone.

So this is all about things you should check when purchasing new smartphone.
