Ascii Codes

It is a very well-known fact that computers can manage internally only 0s (zeros) and 1s (ones). This is true, and by means of sequences of 0s and 1s the computer can express any numerical value as its binary translation, which is a very simple mathematical operation (as explained in the paper numerical bases).

Nevertheless, there is no such evident way to represent letters and other non-numeric characters with 0s and 1s. Therefore, in order to do that, computers use ASCII tables, which are tables or lists that contain all the letters in the roman alphabet plus some additional characters. In these tables each character is always represented by the same order number. For example, the ASCII code for the capital letter "A" is always represented by the order number 65, which is easily representable using 0s and 1s in binary: 65 expressed as a binary number is 1000001.

The standard ASCII table defines 128 character codes (from 0 to 127), of which, the first 32 are control codes (non-printable), and the remaining 96 character codes are representable characters:

*	0	1	2	3	4	5	6	7	8	9	A	B	C	D	E	F
0	NUL	SOH	STX	ETX	EOT	ENQ	ACK	BEL	BS	TAB	LF	VT	FF	CR	SO	SI
1	DLE	DC1	DC2	DC3	DC4	NAK	SYN	ETB	CAN	EM	SUB	ESC	FS	GS	RS	US
2		!	"	#	$	%	&	'	(	)	*	+	,	-	.	/
3	0	1	2	3	4	5	6	7	8	9	:	;	<	=	>	?
4	@	A	B	C	D	E	F	G	H	I	J	K	L	M	N	O
5	P	Q	R	S	T	U	V	W	X	Y	Z	[	\	]	^	_
6	`	a	b	c	d	e	f	g	h	i	j	k	l	m	n	o
7	p	q	r	s	t	u	v	w	x	y	z	{	|	}	~

* This panel is organized to be easily read in hexadecimal: row numbers represent the first digit and the column numbers represent the second one. For example, the "A" character is located at the 4th row and the 1st column, for that it would be represented in hexadecimal as 0x41 (65).

Because most systems nowadays work with 8bit bytes, which can represent 256 different values, in addition to the 128 standard ASCII codes there are other 128 that are known as extended ASCII, which are platform- and locale-dependent. So there is more than one extended ASCII character set.

The two most used extended ASCII character sets are the one known as OEM, that comes from the default character set incorporated by default in the IBM-PC and the other is the ANSI extend ASCII which is used by most recent operating systems.

The first of them, the OEM character set, is the one used by the hardware of the immense majority of PC compatible machines, and was also used under the old DOS system. It includes some foreign signs, some marked characters and pieces to represent panels.


The ANSI character set is a standard that many systems incorporate, like Windows, some UNIX platforms and many standalone applications. It includes many more local symbols and marked letters so that it can be used with no need of being redefined in many more languages:

3 Tips for Keeping Your Brain Strong 74

There are three things that you can do to keep your brain strong. They are keeping your mind active, feeding your body the right food, and exercising your body.
For starters, to keep your brain strong, you should keep your mind active. The best way-perhaps-to do that is to become a lifetime learner. Never stop learning. All of us have things we would like to learn more about. I myself, for instance, would like to improve my knowledge about science. Also, I would like to learn more about ancient societies and evolution. I would also like to expand my knowledge about consciousness, investment, music, and a whole host of other topics-the list goes on. Not only do I want to do all of these things, I am, in most cases, doing something about them by, for example, reading a book on investment, science, or health. You should do the same thing. Find out what you desire to learn more about and make that an active pursuit. You don't need to spend a whole hour doing it, you can simply spend just 15 minutes a day.
Another way to keep your brain strong is to feed your body the right food. Namely, you should eat a lot of salmon and vegetables. Salmon supplies your brain with a lot of omega-3 fatty acids. Not only do they keep your arteries clear so that nutrients can flow unimpeded into your brain, but also they keep your neuro-transmitters functioning strong. As for vegetables, any kind will do the job. It is said that eating only two or more serving a day will keep your mental apparatus in shape.
Finally, to keep your brain strong, you need to exercise. Exercise, some think, is an a panacea for the brain. That is to say that it is believed not only to keep the body strong, but also to do likewise for the brain. In the same way that exercise keep the body with functioning well, it also keeps the mind functioning well also. In other words, it preserves the brain's cognitive functioning from decline.
These are just a few tips that you can adopt so that you can keep your brain going strong: Keeping your mind active, eating the right food, and exercising your body.
