Data held on the hard drive, is considered to be permanent. It will still be there, after the power has been removed for many years.
Random Access Memory (RAM) is the working memory, held on microchips and needs power to keep the data. It will be immediately lost when the computer is switched off. This usually of little consequence as important data is always held on the hard drive.
The RAM is only used for temporary data whilst working.

Do computers store data digitally and ultimately as a stream of only two numbers?
Most digital computers today do.
Is a basic operation of computers.?
Data and instructions in computers are coded with a what because computers only understand two values
Does Logitech make computers?
No, they only make peripherals for computers not computers themselves.
Which IPsec component provides connectionless integrity and data authentication but does not provide confidentiality?
Answer: The Authenticated Header (AH) In the IPSec protocol the only traffic that is unencrypted is the (AH). In other words, it only signs the traffic to retain its authentication & integrity, but no privacy.
The IT manager of a bank is disposing of some computers but the hard drives have some highly confidential data on them What is the recommended way of dealing with the drive to ensure that the data?
The only safe way to deal with old drives is to smash them with a hammer. No electronic means is totsally safe.
Does RAM only holds data temporarily?
Yes
Would changing the battery in a tablet erase data?
No, tablet computers store their data in Flash memory a type of electrically writable read only memory (a solid state replacement for harddisks with no moving parts to break). Flash requires no power to retain data, once that data has been written.
When a computer is off what is in RAM?
Nothing. RAM only stores temporarily data which means when your computer shuts down or resets, all data in RAM is lost.
Do computers understand the data they process?
yes, computers do understand the data they process, they are able to do this because of the processor all computers have in their circuit.
Do computers store data digitally and ultimately as a stream of only two numbers?
Most digital computers today do.
What is a data source that can be used by multiple computers?
wire are the source! jezze, I'm only a second grader!
Is CPU retain the information when power to the computer system is turned off?
No. The microprocessor is simply a bunch of tiny switches that when switched a certain way process data according to a program. When you turn the power off all the switches are reset. To get the microprocessor to set the switches again it needs to get instructions from somewhere else, usually the BIOS, this is what it is doing when it boots. Only the BIOS and the hard drive retain data when there is no power.
Why computer use number system?
Computers cannot understand languages. They can only compute data. Because of that, we use binary code because that is pure data.
Tablet computers are another type of notebook where the keyboard is the only data entry method available?
// This is a statement and not a question! //
Will technology ever replace the accounting professionals?
Probably not. Technology (computers) is only as good as the data that's entered, and it takes someone who knows accounting to know what data to enter into the program. Also, there can be some gray areas in accounting, and computers only deal with "black and white" areas, as in the actual numbers and facts.
Why would you only backup software?
Software and data are much more important than the equipment. Computers can be replaced fairly easily.... data is much more difficult to replace.
Is a shopping list a database?
Yes, a shopping list is similar to the database. As we keep our data in our database(in computers) in that way only we keep the data of items to be bought in our shopping list.
