QUESTIONS LIST:

• direct memory access : assigns the task of outputting data to a dma controller rather than generating an interrupt every time data needs output.
• traps : occurs when the cpu detects an error or an exceptional condition during the execution of a program.
• boot up : is the process initiated when a computer system is powered on or restarted.

• primary memory : it temporarily holds data and instructions that are actively used by the cpu.
• interrupts : signals sent by hardware devices to the cpu to gain its attention.
• speed : is one of the criteria in choosing storage device, defines how fast the device is in providing access to data.
• capacity : is one of the criteria in choosing storage device, defines how much data can it store.
• cost : is one of the criteria in choosing storage device, deals with the practicality of acquiring such device.
