Karten in diesem Stapel (11)
- 1What is Von Neumann architecture?A computer architecture in which a shared memory and bus is used for both data and instructions
- 2The same data bus is used to transfer what in Von Neumann architecture?Data and instructions
- 3The same address bus is used to transfer what in Von Neumann architectureAddresses of both data and instructions
- 4What is Harvard Architecture?A computer architecture which has physically separate memories for data and instructions
- 5Why can Harvard architecture be faster than Von Neumann?Data and instructions can be fetched in parallel instead of competing for the same bus
- 6What is CISC? (Complex Instruction Set Computers)A large instruction set is used with the aim of completing tasks in as few lines of assembly language as possible
- 7What is RISC (Reduced Instruction Set Computeer)Only simple instructions, each taking one clock cycle, can be executed
- 8What is an advantage of CISC?Because code is relatively short, very little RAM is required to store instructions
- 9What is a disadvantage of RISC?Many specialised instructions had to be built into hardware, even though the average program only uses about 20% of them
- 10What are two disadvantages of RISC?1) Compiler has more work to do to translate high-level code into machine code
2) More RAM required to store machine code instructions (because there's more lines of code) - 11What is a co-processorAn extra processor used to supplement the functions of the primary processor (CPU)
