[0:03]In here, we illustrate a character or letter H converted to a machine or binary language.
[0:15]Shown here is the ASCII table, for letter H is under CH or character column, and it has Decimal or Dec equivalent of 72. And hexadecimal equivalent of 4 8.
[0:38]To solve, we put a bar, a separator for the hexadecimal 4 and 8. Then for each, we think of binary numbers or digits that will have a total for each using weight values. Weight values are here: 1, 2, 4, 8, and here, 1, 2, 4, 8. You might be asking why there are two separations. Because, 8 and 8, that's a total of 16, and that's equivalent to Hexadecimal, that's why we put a bar here. Talking about weight values, looking at this table.
[1:39]Binary numbers or base 2 raised to 0 is 1, 2 raised to 1 is 2, 2 raised to 2 is 4, 2 raised to 3 is 8, 2 raised to 4 is 16, and so on and so forth. And we can have as many as 2 raised to 8, and that's equivalent to 128. And we will be getting this if we try extending this table to the left.
