An 8-bit ADC has an input range of 0 to 10 volts and an output range of 0 to 255 (called straight binary). What digital value will be returned when an input of 7.5 volts is sampled?

converting 191.25 to Binary 110011

Explanation:

Input range = 0 to 10volts

output range = 0 to 255

first we have to determine the resolution

= output range / input range

= 255 -0 / 10 - 0

= 25.5

when an input value of 7.5 volts is sampled

digital equivalent o/p voltage = 7.5 * 25.5

                               = 191.25

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
