When you delete a file from the trash bin, the data is still there for the file but the reference to the file (the area on the storage device that shows where all the files are) is deleted. You can permanently delete a file by using a program, such as Eraser (http://www.tolvanen.com/eraser/) that writes random data where the file was.
The computers memory card.
The CPU
Make sure you quit all running apps and then if it still doesn't work, restart your computer and then delete the items in trash.
it is the memmory which is used by the computer to save it virtual and physical memory and some deleted files which are deleted from the recyclebin
There are two types of memory in a computer - volatile and non-volatile. Volatile memory is the Random Access Memory (RAM) which is lost after the power is cut. The non-volatile memory is the hard drive which permanently writes information (binary code) to metal platers using magnet charges. After the computer is powered off, the magnetic charges do not change.
Computer printers do indeed have replaceable memory. These computers are relatively new in age and have many wonderful memory features.
a hard drive stores the computers information, while the RAM (random access memory) can store temporary things like your history etc that get deleted when you turn off your computer
No dear computer don't have ROM
It holds programs in its memory so you can multitask. Plus a program needs memory to be run. All computers need memory.
a computers memory can be improved by adding another harddrive on the computer and/or removing files that you dont use( do not remove files if you dont know what they are)
when you increase memory you have more space on computers and greater memory with have more impact than lower memory
The memory of a computer may be verified by checking the RAM in the System folder. If one wishes to add more memory to one's computer, it is sold by Newegg and Tiger Direct.
