Week One

The first week of OCR Computing began with an introduction to key terms; "what is a computer?" I now know its a device that can input, store, manage and output data, a calculator.
In more depth, I learnt about Binary code and ASCII table. Binary is the code a computer uses to calculate and display letters on the output (e.g a computer screen). To work out binary its simply many 0's and 1's placed into the binary table and added up:

128	64	32	16	8	4	2	1
0	1	1	0	0	0	1	1

To work it out you simply add up all the numbers displayed by 1's;  the above adds to 99 and corresponds to letter C in the ASCII table.

So:
A computer is a device that process, inputs, stores, manage and outputs data.

The Binary table headings are easily remember by simply doubling the amount each time from right to left. 128, 64, 32, 16, 8, 4, 2, 1.
