What is computer data made of?
Computer data is information processed or stored by a computer. This information may be in the form of text documents, images, audio clips, software programs, or other types of data. Computer data may be processed by the computer’s CPU and is stored in files and folders on the computer’s hard disk.
What exactly is computer data?
In computing, data is information that has been translated into a form that is efficient for movement or processing. Relative to today’s computers and transmission media, data is information converted into binary digital form. Raw data is a term used to describe data in its most basic digital format.
What is data physically made of?
And physically it’s nothing more than wires, discs… Metal, silicone, plastic with layer of some electrically active material (CrO2 to name one)… There is no magic in it.
Can data become physical?
First of all – computer data are an information, so it physically doesn’t exist. Information is not a thing you can touch. Computer full of data has the same weight as empty one.
What is digital data physically?
Yep it is always physically located somewhere in 1s and 0s. The form of those 1s and 0s can be different. Use can use magnet dipoles, or electric current or whatever but its has to be in the form of an on or off switch. [
What is the physical part of computer called?
Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.
How do computers use data?
data processing, manipulation of data by a computer. It includes the conversion of raw data to machine-readable form, flow of data through the CPU and memory to output devices, and formatting or transformation of output. Any use of computers to perform defined operations on data can be included under data processing.
What is a bit physically?
Physical representation A bit can be stored by a digital device or other physical system that exists in either of two possible distinct states. In most modern computing devices, a bit is usually represented by an electrical voltage or current pulse, or by the electrical state of a flip-flop circuit.
There’s various different forms of computer data. In RAM, and while the CPU is working on it, it’s simply electricity; often +3.3 volts of electricity means “1”, while 0 volts means “0”. All data is made out of 1s and 0s stringed together; for example, the letter A can be represented as 01000001.
What are the components of a computer?
Let’s review some of the standard computer components and you’ll hopefully learn something today! The motherboard is an important computer component because it’s what everything else connects to! The motherboard is a decently sized circuit board that lets other components communicate.
What is a hard drive and how does it work?
The traditional hard drive consists of several spinning platters with an arm that physically writes data to the disk. However, these drives are slow and are starting to be replaced by the faster solid-state drives. Solid-state drives consist of flash memory, like your smartphone or flash drive.
How is data stored on a hard disk?
All data is made out of 1s and 0s stringed together; for example, the letter A can be represented as 01000001. On the hard disk, it’s stored as magnetic fields on something called a “platter”.
