Computational Thinking

Computational Thinking

1. Computational thinking allows us to take a complex problem and make it understand more.

   • Breaking down a complex problem or system into smaller, more manageable parts.

   • Input
     • An input device is any piece of computer hardware used to provide data to a computer system.
   • Output
     • An output device is any piece of computer hardware used to communicate the results of data that has been processed.
   • Storage
     • A storage device is a piece of computer equipment which can be used to store data.
   • Hardware
     • The physical parts of a computer system, eg a graphics card, hard disk drive or CD drive.
   • Solid State
     • Solid state devices use non-volatile random access memory (RAM) to store data indefinitely.
   • RAM
     • Random Access Memory (RAM) is a fast temporary type of memory in which programs, applications and data are stored.

   • Folder/Sub-folder
     • A sub-folder is a folder inside another folder.
   • File
     • Anything you save. It could be a document, a piece of music, a collection of data or something else.
   • File Management
     • The organisation of files and folders using suitable names (which gives the identity of a file) and placed into folders.
   • Server
     • A computer that holds data to be shared with other computers. A web server stores and shares websites
   • Password
     • A string of characters used to verify the identity of a user
     • A good password is then no one can get on.

4. E-safety

   • Do not share personal information (such as your date of birth)
   • Avoid sharing your location on social networks eg snapchat
   • If meeting someone you only know online, do so in a public place and take an adult with you.
   • Don’t troll! (upsetting people online)
   • Change your passwords frequently and avoid using the same password across all accounts

5. Cloud Computing Advantages

   • Backing up - data backed up in the cloud with a reliable provider can be more reliable than storing your information on a hard drive or USB flash memory stick.
   • Compatibility - documents and files are designed to be compatible across different machines and browsers.
   • Cost – the user doesn’t need to buy the latest software as it might be freely accessible through web apps.
   • Independence – the user can work with their files on different computers.
   • Reliable software - web software and browsers are updated online. The user doesn’t have to download the latest updates.

6. Cloud Computing Disadvantages

   • Connection – the user can only access their information if they have a network connection.
   • Copyright – the user sometimes loses legal rights to their original material if they store it online.
   • Security - data stored online is vulnerable to security attacks.
   • Storage - it is not always possible to store more than a few gigabytes online with one provider, whereas it is possible to purchase a few terabytes of physical storage to save information at home.
   • Software - web apps do not usually have as many detailed functions as a full software package.
