Computer Architecture
| Question | Answer |
|---|---|
| Memory location | A separately addressable area of main memory |
| RAM | Random access memory – volatile main memory |
| ROM | Read-only-memory – non-volatile main memory that cannot be written to once it is set up |
| EEPROM | Electrically erasable programmable read only memory |
| Computer bus | A set of parallel wires connecting independent components of a computer system |
| System Bus or External Bus | The main highway connecting the processor, main memory and I/O controllers |
| I/O | Allows CPU to communicate with peripherals |
| In RAM how does the read/write speed compare? | Same access time for all writing and reading operations |
| What is the system bus/external bus made up of? | Data bus, address bus, and a control bus |
| In EEPROM how does the read/write speed compare? | The write speed is a 100 times slower than the read speed |
| Peripheral | A computer device that is not part of the CPU. It can be external or internal |
| I/O device | A hardware unit that sends or receives data or stores data by communicating with the processor and main memory through an I/O controller |
| I/O controller | An electronic circuit that connects to a system bus and an I/O device |
| Secondary Storage | Permanent storage memory not directly connected to the processor; also called backing store |
| What does an I/O device communicate with and how? | It communicates with the processor and main memory through an I/O controller |
| How does an I/O controller work? | It provides the correct voltages and currents for the system bus and the I/O device |
| Main memory address | A unique numeric code corresponding to a location in memory |
| Stored program concept | A program must be resident in main memory to be executed |
| How is a program processed in the stored program concept? | It is processed by fetching machine code instructions in sequence from main memory and executing them, one at a time, in the processor |
| Register | A very fast memory location located inside the processor or I/O controller |
| General-purpose register | A register not assigned a specific role by the processor designer |
| Dedicated register | A register assigned a specific role by the processor designer |
| Programmers and registers | Programmers may use general-purpose registers but programmers may also use some but not all dedicated registers |
| Clock speed | The frequency in megahertz or gigahertz at which the processor executes instructions |
| Word length | The number of digits in a binary word |
| Bus width | The number of signal wires or lines allocated to the bus |
