What are Input and Output Devices?!
Input Devices are Such things as Keyboards,Or Computer Mice. They are Components that Allow Users to Enter Data Such as Instructions. Without Input,theirs no Output!
Now,to Output Devices:
Output Devices Are Like Computer Screens Or Printers. Output Devices are Components for Showing the Results of the Input. if you type in "Abc" on the Keyboard,the Screen will show "Abc" Back! That's How you can read my Information Right now!
Whats the Difference Between Soft Ware and Hard Ware?!
- Hardwares are Nearly Always the Same Old Basic Thing.
- A Computer System Consists of Inputs,Output,Processing and Storage Devices. So Without a HardWare,Or a Hard Drive (A Type of Hardware) the Computer will just not work Properly!
- You Cant Physically Touch it! its just like Thin Air...
- Software is used to Create Loads of Instructions,Usually Stored or Saved For Later Use Which the Computer Can Follow. An Example of this is Computer Codes!
Wait Wait Wait... Whats a HardDrive?
A Hard drive or a Flash disk Is Used for Storage. You Can Hold These! Now,not everyone Likes. Imagine If you lost it,or Broke it? All information Gone! But No,Instead We Now have...
Before you Ask,it IS a SoftWare,Not Hardware! Cloud Storage is Useful Because It has a Very Large Capacity And Can Be Accessed by other Portalable Devices that have Internet Connection,Like phones or IPad! it Allows Businesses to Provide a Large Amount of Different Ways to Access Files and Data.
How can i Protect my Stuff?! Easily!
the Fancy Word for A password is a Encryption Key. An Encryption is The Scrambling of Data to make it Unreadable To Anyone,Unless you have the Correct Key!
To Fancy For you? How About Using a SSID? An SSID (Actually Meaning The Service Set Identifier Device) all have a Different and Unique Code,So that all Connected Devices Can Identify it.It must be used by all Devices on the Network so they Can Communicate with Each Other, So you could Have a phone Connected to a Computer without any Wires! Amazing! If you Dont have a SSID,or if someone finds out When you Dont want to, Anyone can get onto your Router! (oh no!) But no Threat! you Can Hide it! So No Sweat!
