Important HTML Tags

I was going through the html course in W3schools then
I find some important tags which i had never used in html, so
here are these tags :
<del> // delete with line
<ins> // insert in stead of delete
<mark> // gives color to text
<cite> // Title of the work
<q> // Short Quotation
<map> // tag is used to define a client-side image-map.
An image-map is an image with clickable areas.

Difference Between apt-get update and apt-get Upgrade

  • apt-get update updates the list of available packages and their versions, but it does not install or upgrade any packages.
  • apt-get upgrade actually installs newer versions of the packages you have. After updating the lists, the package manager knows about available updates for the software you have installed. This is why you first want to update.
  • You should first run update, then upgrade. Neither of them automatically runs the other.
