Hello everyone! I have 16 GB of RAM installed in my PC, and although the task manager and PC recognize that 16 GB is installed it only tells me that 7.9 GB is usable and 8.1 is reserved. What does this actually mean? And why does it show that only some part of my RAM is usable and the rest is reserved? Any ideas?

Hello! I am not able to download anything on my phone from Google Play Store. It gives an error and says "Insufficient memory in memory card". How is this possible? I only have WhatsApp installed in my phone, no other app. The rest of the things are there by default like Google Maps, Google+, YouTube etc. This shouldn't be happening as the memory card has the storage capacity of 1 GB. What is the reason? Thanks in advance!

Hello! So when someone says that the maximum capacity of a particular computer is lets say 2 GB, what does this statement exactly mean? What if I have a computer whose maximum RAM capacity is 2 GB but I add more RAM in it, will it work properly or not?

Hello! I have a few questions related to virtual memory. The questions are the following:

1) As the name suggests it is not a real memory so does it actually exist?

2) Is it more in storage than the RAM and hard disk?

3) Is it faster than RAM and hard disk?

4) What kind of circumstances forced us to use virtual memory?

Hello! When we save something in our computer, we know it gets saved in the hard disk on permanent basis. So consider this situation, I am working in MS-Word and when I click on the icon to save my document and when it is saved, what exactly happens in the hard disk and in what manner is the document saved in the hard disk? I mean we all know computer understands only binary(0 and 1) so this procedure must be complicated, right?
