Does size of ram matter on website hosting?

What is the purpose of ram for my websites server, does size even matter? How is ram memory being used for hosting a website on a server. Does loading pictures on the website increase the memory? What do I have to be careful of not exceeding the memory capacity?
Answer #1
it depend on what type of website that you are running
Answer #2
Yes it does.
Its basically determines how many simultaneous connections your site can have. 1 visitor ~= 1 connection. Loading anything increases the memory, by how much that is dependent on the engine being used. What you need to do differs on what engine is being used to host the site.

Answer #4
It’s a VPS/Dedicated server I assume? How much RAM does it have and what OS is it running? If Linux,You could see memory usage
stats by typing top from SSH. Which webserver are you using? (apache,lighttpd,nginx)
Generally speaking,RAM usage depends on all running processes and not just the webserver’s one,It can get a little higher if you got a high number of concurrent visitors,But usually not by significant amounts unless the scripts are really resource intensive,It also depends on the webserver’s memory management,Apache is not exactly resource friendly,The number of PHP processes & how much connections each of em can handle matters too and this can be controlled from the webserver’s configuration file.

No,1 script/image = 1 connection. 1 visitor can easily make more than that.

Wrong,No correlation between the RAM usage to this,On Linux this is determined by the following:
1. Max number of open file descriptors (1024 by default)
2. Max number of connections on the webserver’s configuration (will have to be manually compiled to handle more
than 1024 if FDs are modified)
