I know there are many answers to this question on askubuntu and google.com.

I have to ask for suggestions and difference between

  1. Live USB
  2. Installed USB

I want to install Ubuntu on Flash Drive so that I could use it on any system. Before that, I have some list of questions which requests answers to them.

  1. Can an application be installed in live mode for later use
  2. Which will be best : live USB or installed USB
  3. Which bit version (64 bit or 32 bit) will be suitable so that USB can be used to boot in systems with low configuration as well

I want this so that I could carry data and applications and boot using my USB and do my stuff from anywhere on any system and even If required the same USB could be used to install Ubuntu on other systems.

It is possible create a live USB that allows you to install apps and save that configuration, but it is not recommended.

The biggest difference between live and a full install is that on a live session, pretty much everything you run or install gets loaded into memory, and is lost when you reboot, unless you create a special live USB.

My recommendation: Install a lightweight, 32-bit version of Ubuntu, like MATE or LXDE onto your USB. Keep in mind that you'll need a speedy and fairly sized USB drive in order to get a pleasant experience.

See Difference between LiveCD, LiveUSB, full-install, and persistence? for comparison between Live Persistent and Full installs.

Mkusb makes a persistent install that pretty much closes the gap between Live and Persistent installs, the persistent boot takes a little longer and installing proprietary drivers is still not possible.

A mkusb drive can be used to install Ubuntu.
