A bit pattern is shown below.
01001110
Convert the bit pattern into decimal.

78

Explanation:

I always convert to hexadecimal first:

0100 = 4

1110 = E

(the matching of groups of 4 bits to one hex char is a lookup you can memorize)

so we have 4E, which is 4*16+14 = 78

Of course you can also go the long route:

01001110 = 0·2⁷+1·2⁶+0·2⁵+0·2⁴+1·2³+1·2²+1·2¹+0·2⁰ = 78

answer; i believe that technician b is correct;

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.
