1.1- Memory (Computing)
Cards in this deck (4)
- 11) Input Process Output 2) Keyboard Microphone Moisture sensor 3) Headphones, Monitor, Motor 4) Stored program computer system5) Clock speed, Cores, Cache
6) The CPU directs the flow of data around the computer system and processes instructions - 27) ALU 8) CU 9) PC10) MDR stores data that is being processed when fetched from RAM
11) PC, MAR, Acc., IC, RAM - 312) To get the instruction The CPU fetches this from the RAM and stores it in the CPU temporary memory, the registers. Once the instruction has been fetched, TO DECODE IT the CPU will need to understand the instruction to action it THIS IS DONE IN THE CU.12cont) CU will execute this if it understands it and sends to IC incase of reuse. If not the computer will crash. Then the CU sends the Calc. to the Acc in the ALU. The next address is in the PC.
- 413) Laptop 3 - CPU more powerful = complete more instructions that the game will give faster. Clock speed = 2nd fastest but still fast enough at ---GHz, Most cores = process more instructions simultaneouslyDas all
