How do computers store data without power?
Flash memory is a storage technology that uses a floating gate cell design to remember its state before being switched off, thereby retaining data regardless of active/inactive power supply, making it a durable form of read, write, and erase memory..
How does a computer get data?
Input: Getting Data from the User to the Computer.
Some input data can go directly to the computer for processing.
Input in this category includes bar codes, speech that enters the computer through a microphone, and data entered by means of a device that converts motions to on-screen action..
How does a computer save memory?
Whether it comes from permanent storage (the hard drive) or input (the keyboard), most data goes in random access memory (RAM) first.
The CPU then stores pieces of data it will need to access, often in a cache, and maintains certain special instructions in the register.
We'll talk about cache and registers later..
How does storage work in a computer?
Memory is what your computer uses to store data temporarily, while storage is where you save files permanently.
When you save a file, it's copied from the memory onto the storage drive.
This is why your computer seems to run slower when it's low on memory; it has to pull data from the storage drive in order to use it..
Secondary storage devices
Computers process information by performing logical operations on binary data.
Such operations are performed by logic circuits, as described in the last two chapters..
