- 1Input- A piece of hardware that puts data into the computer. ( Mouse, Keyboard, Scanner, Sensor, Microphone)Output- Hardware that displays the instructions given by the input and processed by the CPU. (, Printer , Projector, Speaker/headphones, Monitor)
- 2—Peripherals connect to the processor hardware through the motherboard. External devices will connect to the motherboard via USB, FireWire or through a wireless connection such as Bluetooth.
- 3Motion sensors send a beam of light out and can detect if the beam is broken. They may also use radio or sound waves, which will be reflected back if they are interrupted. However, most security systems use passive sensors. These don't send signals out, but wait to receive a signal in.( Wii mote, Kinect and Leap motion)Screen - used to give us access to the programs and the file system through a command line interface (CLI) or a graphical user interface (GUI). Most screens make use of LED or LCD technology.
- 4Command line interface - a method of running programs and working on a computer using only text. This contrasts with a graphical interface which uses clickable icons and menus.Graphical user interface - used to interact with a computer through icons and menus.
- 5Storage is non-volatile disk space, and is sometimes called auxiliary memory, secondary memory or external memory. Storage devices, like an external hard drive are used to store files like photos, program files and any other information that needs to kept long term. The data on a storage drive needs to be loaded into RAM before it can be used.A form of computer memory that stores data even when not powered.
- 6Hard-drives contain a vast amount of space and now-a-days have minimum usually 500GB.Random Access Memory (RAM): Memory that is constantly being written to and read from. It does not retain its contents without a constant supply of power, eg when a computer is turned off, everything stored in its RAM is lost.
- 7Most computers have internal storage space. The internal storage drive stores the operating system and software applications. It is normally a hard disk drive (HDD) or a solid state drive (SSD).External storage
External HDDs and SSDs can also be used to store data. USB memory sticks, memory cards, CDs and DVDs are convenient external storage media. They are normally connected to a computer using USB or FireWire connections. - 8—
