Explain segmentation?
Segment memory addressing divides memory into many segments. Each of these segments can be considered as a linear memory space. Every one of these segment is addressed by a segment register.
Though since the segment register is 16 bit wide and memory needs 20 bits for an address the 8086 appends four bits segment register to attain the segment address. Hence to address the segment 10000H by, say SS register, the SS should contain 1000H.
How many bits are required at the input of a ladder D/A converter, if it is required to give a resolution of 5mV and if the full scale output is +5V. Find the %age resolution.
