- Question
When the term RAM is used with semiconductor memories, it usually means ________ as opposed to ROM.
Options- A. Random-Access Memory
- B. Read/Write Memory (RWM)
- C. flash memory
- D. temporary storage
- Correct Answer
- Read/Write Memory (RWM)
- 1. What does ECL stand for?
Options- A. It stands for electron-coupled logic; all of the devices used within the gates are N-type transistors.
- B. It stands for emitter-coupled logic; all of the inputs are coupled into the device through the emitters of the input transistors.
- C. It stands for emitter-coupled logic; all of the emitters of the input transistors are connected together and each transistor functions as an emitter follower.
- D. It stands for energy-coupled logic; the input energy is amplified by the input transistors and allows the device to deliver higher output currents. Discuss

Options- A. a short abbreviation for the operand address
- B. a short abbreviation for the operation to be performed
- C. a short abbreviation for the data word stored at the operand address
- D. shorthand for machine language Discuss
