Answer:
A HUB
Explanation:
A hub can described as an hardware or network device use for multi purpose functions like connecting series of internet devices together there by making it possible for all devices to work or function together on a single network.
Hubs are classified into active hub, passive hub, and intelligent hub.
ACTIVE HUB: This type of hub boost the signals but can not perform calculations.
PASSIVE HUB: this type only send the signals but can not boost a signal.
INTELLIGENT HUB: it brings about the boosting of signals and also bring about packets to be analyzed.
Answer: A. Flying a paper airplane.
Answer:
oid changeCase (char char_array[], int array_size ) {
__asm{
mov eax, char_array;
mov edi, 0;
readArray:
cmp edi, array_size;
jge exit;
mov ebx, edi;
shl ebx, 2;
mov cl, [eax + ebx];
check:
//working on it
cmp cl, 0x41;
jl next_indx;
cmp cl, 0x7A;
jg next_indx;
cmp cl, 'a';
jl convert_down;
jge convert_up;
convert_down:
or cl, 0x20; //make it lowercase
jmp write;
convert_up:
and cl, 0x20;
jmp write;
write:
mov byte ptr [eax + ebx], cl
next_indx:
inc edi;
exit:
cmp edi, array_size;
jl readArray;
mov char_array, eax;
}
}
Explanation:
- Move char_array to eax as it is base image
.
- Use ebx as offset
.
- Use ecx as the storage register
.
- check if cl is <= than ASCII value 65 (A)
.
Overflow occurs when the magnitude of a number exceeds the range allowed by the size of the bit field. The sum of two identically-signed numbers may very well exceed the range of the bit field of those two numbers, and so in this case overflow is a possibility.
