- 1RISC- Reduced Instruction Set Computer. Only simple instructions with each one only having one clock cycle each. Can be Pipelined. Has limited complexity.CISC- Complex Instruction Set Computer.
Lots of different mnemonics.
Doesnt have as much code to write = takes up less RAM and the compiler has less work to do.
Really complex. - 2Advantages of RISC: Know how many clock cycles will be used whereas CISC is unknown. Able to do Pipelining. Cheaper to produce.Disadvantages of RISC:
Takes up more RAM.
Compiler has more work to do translating the code. - 3Advantages of CISC: Short code takes up less RAM. Language can easily be translated.Disadvantages of CISC:
Quite expensive to produce.
Can't do Pipelining on this.
Only has 20% of capability. - 4Examples of Inputs: Keyboard Mouse Scanner Touchscreen Card Reader ControllerExamples of Outputs:
Printer
Monitor
Speakers
TV
3D Printer
Projector - 5A concept keyboard that can be used in restaurants to serve customers and has options on it instead of a keyboard and also has images of products.Sensors used in a car:
Touch sensors to detect if it is raining
Light sensors to detect the time of day and if the headlights need turning on
Ultrasonic sensor for parking assists - 62D Barcodes: Stores more information than a traditional linear barcodeLinear Barcodes:
Used in supermarkets and can only store the number below it. - 7OLED screens: Brighter and thinner than LCD/LED Screen is plastic which makes it more flexible No backlight = Less power used Responds up to 200 times faster Not as Long LastingLCD Screens:
Can lose clarity at different angles
Last almost indefinitely
Consumes little power and produces little amount of heat. - 8Virtual Storage Services: Drop Box- 2GB free storage, costs $9.99 per month for 200GB OneDrive- 5GB free storage, costs $2 per month for 50GB Google Drive- 15GB free storage, costs $1.99 per month for 100GB iCloud- 5GB free storage, $0.99 per month for 50GB
