Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
A portable computer was a computer designed to be easily moved from one place to another and included a display and keyboard. 
The first commercially sold portable was the 50 pound IBM 5100, introduced 1975. The next major portables were Osborne's 24 pound CP/M-based Osborne 1 (1981) and Compaq's 28 pound 100% IBM PC compatible Compaq Portable (1983).  These "luggable"s lacked the next technological advance, not requiring an external power source; that feature was introduced by the laptop. Laptops were followed by lighter models, so that in the 2000s mobile devices and by 2007 smartphones made the term almost meaningless. The 2010s introduced wearable computers such as smartwatches.Portable computers, by their nature, were generally microcomputers.  Larger portable computers were commonly known as 'Lunchbox' or 'Luggable' computers. They were also called a 'Portable Workstation' or 'Portable PC'. In Japan they were often called 'Bentocom'. (ベントコン, Bentokon) from "bento".
Portable computers, more narrowly defined, were distinct from desktop replacement computers in that they usually were constructed from full-specification desktop components, and did not incorporate features associated with laptops or mobile devices. A portable computer in this usage, versus a laptop or other mobile computing device, had a standard motherboard or backplane providing plug-in slots for add-in cards. This allowed mission specific cards such as test, A/D, or communication protocol (IEEE-488, 1553) to be installed. Portable computers also provided for more disk storage by using standard disk drives and providing for multiple drives.
