I still remember my first contact with computer, it was 1993, i was 
just arrived in mexico and it was my third day in 
school, it was wednesday, i was storing my books in my bagpack when 
suddenly my computing teacher arrived 
(i was 8 years old), he asked us to go to the computing lab, i arrived 
and saw some monitors with a keyboard on it,
i didn't know what was it but then, suddenly, i turned it on and saw 
lot's of letters and numbers, i liked that, then my
teacher gave me a 5 1/4 inches disk (that was the DOS) and told me to 
insert it, i did what he told me, (the machines
where 80286 at a real low speed without a HD and with a non-expanded 
(the ones without the numbers in the left) and a 5 1/4 inches drive, i 
just can't forget it) then after DOS had loaded
i inserted a disk i found on my left, when it runned my teacher told me 
its name was "logos" (old and truty logos)
with it i made a lot of images and one day when i was bored of doing so 
i asked my teacher to make a copy of the
program for me, he told me no, if i wanted that copy i had to make it 
myself, so i did and it was cool!!!
i arrived with my all mighty powerful disk, inserted it on the drive, 
and typed the command "copy a: to b:" 
and i followed like that until the disk was finished copying, and what 
was my sorprise when i runned it the next class
that i copyed the version with teh one you can make music (weeelaaaa), 
so i maked my first song, and then my life
starts becoming more related to the computers to the point that my 
fathers buyed me one on 15 october of 1999,
a CELERON at 400Mhz with 32Mb in RAM, and from the time i'm writting 
this is still here alive, with me, but with
more RAM and a burner, hehehe, anyway, that is my history, isn't it 
1.- Computing History
Computers were made a lot time ago by the men to make things easier in 
a certain way, at first they were big pieces
of metal in a very cold room managed by the most experimeneted people f 
the world and only military and goverment
had them, their info was stored in hard plastic cards with holes in it 
(like the braile language (blind people language
in case i miss spelled)), these cards were passed by a machine that 
counted the holes on the card and processed the
info it read.
then the magnetical computers came, these machines were different,. 
thought they were also very big and were all
day processing info, theynwere a lot faster, the data was stored in 
magnetical tapes, this machine were as big as a
conference room (a medium size one), they also needed to be in very low 
temperatures so they could work properly.
After this a long time passed and the personal machines came.
1.1 hardware
The first personal machine that existed were the commodore, these 
machines tought they were like computers they
were more focused on games, finally in the late 80's the first personal 
computer went out and saw light, the 8086
from IBM, this machine had no more than 5 Mhz of process speed and no 
more than 512Kb on RAM, this computer
was real powerful but too expensive to afford for many people so not 
everybody could had one, then a few years 
later the 80186 saw light, this computer was cheaper, faster and way 
much cooler, then we had 80286 (now on all
the computers with that kind of processor, for make it shorter the omit 
the 80, example: 80486=486, and nowadays
they are called X86 (86 caused thay have, in some way, a similar 
structure), then 386, 486, 586 and 686, the lasts
ones where someway like the pentium and pentium-2 but with lower 
performance (just like celeron nowadays), all
machines where great, but, there was a big step on the 486 processors, 
there were two kinds of processors, the 486SX
and the 486DX, the difference (if remember right) was that one had way 
much better performance than the other and
besides DX processors had better architechture, but that is not the 
important thing, the important here was the DX2
these processors were developed almost 4 months before the pentium came 
out, the new and dynamic about these
ones were the mathematical co-processor that made things way much 
faster, cooler and better, from that time all
machines were made to have that processor, what this co-processor makes 
is that if you are running an instruction
and the main processor is busy but you have other instructions waiting 
to be processed the most important ones
are sent to the main processor and the otehrs are sent to to the 
co-processor and stored in there, is in someway like
the cache memory, anyway, after ths th pentium came, it was the hell of 
a processor, tought the first one was at 66Mhz
it was really good, then two years later the pentium two processor came 
out, from this time everything got shooted up
everything started going faster in this time, the initial speed of this 
machine was of 233Mhz and only one year later the
pentium 3 came out, it's initial speed was of 550Mhz, and then only 9 
months later pentium-4 came out with an initial
speed of 1.2Ghz, and so on, right now the new 64 bit processor is being 
developed and is supossed that it will be ready
on second semester of 2003, this one is going to be the hell of a 
processor, tought the first one is only going to be at
1Ghz of speed is going to run like a pentium-4 at 3Ghz and even better, 
it's artificial intelligence unit is going to be
500% more exact than the one of pentium-4 and is supposed to have 4Mb 
of cache memory, with a minimum amount
of RAM of 1Gb and another ton of things (no it can't think for itself 
yet... wait, it does!!!! aaaaaaah!!!!!, no hold on...
yeah, well, what??? phew!!! it was only the artificial intelligence 
unit, it is programmed for that, hehehe, j/k)
so in a pair of years be sure that i'm buying one, besides with those 
specs, who wouldn't??? the creator of macintosh?
1.2 Software
"before saying anything i must say that due to the short knowledge i've 
got about linux/unix history i'm not writting
nothing about, all info about this send it to: 
The first OS for a machine wasn't very cool, it was just the cursor on 
a black screen and all the instructions were
interpreted by commands (no it wasn't ms-dos, and less microsoft OS), 
but then when the first personal computer
went out to the market (yes, the IBM personal computer), it had an IBM 
OS much likely ms-dos but harder to use, and
then microsoft appeared with it's MS-DOS (MicroSoft - Dinamyc Operative 
System), everybody tought it was a wonderful
OS (or almost everybody), i'm sure you are asking "what???, that piece 
of crap????", well it was the first OS wich let
you manage all your files in a simple way, microsoft amde a contract 
with all hardware companyes (excepting apple)
so all of their systems had the lovely MS-DOS on it, this is how 
microsoft monopoly started, then in 1989 
(if i remember well) windows went out to the market, this was software 
boom, why??, well it was the first graphic OS
in the world, you could manage everything with a graphical interface 
(no more commands and lots of simbols in the
screen, everything was suposed to be easier), but, well yeah, lots of 
errors, but not talking about microsoft mistakes
in here, anyways, a few years later windows 3.1 came out, this one was 
almost the same as windows 3.1 but faster 
and with less errors and bla, bla, bla, a few months (or years don't 
remember wuite well, i think it was on 1994)
windows 3.11 saw light, this was most like a patched version of windows 
3.1, so no much to talk about this version
tought it had some new things it was, like i said, like a windows 3.1 
patched version, then in 1995 glorious windows '95
came out, now, this was a great OS, no more windows 3.1 kind OS, it had 
a totally new interface, it was hell easier to
use, it was better looking and also it was a 32 bits based OS, also 
some time before windows '95 came out a windows
called windows NT hitted the market, this windows was meant to be for 
servers, it was designed to be for high speed
machines and bla, bla, bla, you know to work in the net, then  years 
later (and two more NT windows later (version 2 
and 3)), windows 98 came out, it was hell cool???, no!!!!, it was the 
worst OS in the market, tons and tons of errors
you couldn't spend 3 hours in front of your computer without restarting 
it cause windows crashed, it was very unstable
then in 99 windows second edition was released, this was the real 
windows '98 thi really was an OS, no erros, very
stable, bla, bla, bla, all that hings we already know and have heard a 
lot of times, (by the way, before i forget to write
NT technology wasn't based on the MS-DOS and was supposed to be more 
stable than any other windows (that means
no crashing), and yeah that is right, but almost nothing is compatible 
with it, for the reason that it has got a totally
different structure than any other windows), then also in 99 windows 
NT4 came out, no big deal for me, cause i n don't 
use it but some others like it, then in 2000 famous windows 2000 came 
out, this was suposed to be a cool OS intended
for server, profesional and personal use, but it's name was disguissed, 
the windows 2000 was named windowsNT5
but they name it 2000 for commercial purposes, marketing and that kind 
of things, then at the beginning of the 2001
windows ME (Millenium Edition) came out, this was a great OS when 
installed correctly, otherwise was just trash,
i personally like it a lot, tought my machine is kind of old it works 
great, you just have to configure it right, this OS
is the first non MS-DOS based personal OS, it had a totally new code 
(different from windows '9x and NT), and besides
it is compatible with any 9x aplication so it has got almost no 
incompabilities, (just for some recovery system tools
that are not compatible like symantec utilities and so, but thay have 
got patches so is not big deal), and then,
also on 2001 new windows XP (windows eXPperience), came out, this is 
supossed to be the most secure OS in the
market, anti-cracking OS and so, ha!, only two weeks later of it 
release you could buy a cracked version of it for only
US$1.30, so, i don't like it too much, but something is something, 
there are going to be to versions of this OS, the
32 bit version (alredy in the market) and the 64 bit version, this one 
is intended for the intel itanium new processor
and the new AMD 64 bit processor, supossde to be realeased on 2003 (or 
sooner, who knows)
2.1 components
computers are maked of hardware, and hardware has got lots of variants, 
nowadays the only component you don't need
to run a machine is sound card and a mouse, they are optional, bu if 
you want to take full advantage of it you need these
things, ok, the machine has got the next components:
chasis: where you put all your hardware in, this is hot hardware cause 
it only has got 1, 2 or 3 buttons (power on/off,
reset and suspend) 3 or less slets (little low voltage lights) and a 
few apir of cables to connect buttons with the 
mother board and the slets, in other words is the outside part of a 
normal computer (i say this cause there are guys (like
me) that remove the chasis, or part of it, and have all hardware at air 
for faster changes, for example taking HD (Hard
Drive) out and putting in another one, this only recommended for 
advance users))
Mother Board (MB): this is one of the main parts of the computer, 
thought all are important this is the most important
one, why??, easy, here is where you plug all hardware in. processor, 
modem, sound card, etc...
Processor: there are several kinds and brands of processors, but they 
all have only one function; to compute all the
data we want to, for example if you open word a set of instructions is 
sent to the processor and then interpreted by the
different parts of it, finally it gets back the instruction already 
interpreted to you and vouala, you just opened word.
RAM (Random Acces Memory): what the heck is that?????, well this is 
that thing that makes your machine read 
everything, it stores the data of a program so it keeps loaded and you 
don't have to load it each time you want to make
something in it, for example; if you just opened word what RAM does is 
store the set of instructions in there so each
time you type a letter or the programs needs to do some process it 
doesn't has to load again, you probaly asking:
what about if my memory is low or finishes?? why does other machines 
with a higher amount of RAM goes faster
than mine???, well basicly when you store your info on RAM it needs an 
amount of space, for examle word 2000
needs 22Mb each time is opened, so if you have 32Mb on RAM you still 
have 10Mb of free RAM (of course that 
you really don't cause windows also needs of this memory so it really 
depends on the amount of RAM you have
and the programs you are running at that instant)but if you runned out 
of physical memory (RAM is called Phisical 
memory and there is another one called virtual memory) it uses the 
virtual memory, virtual memory doesn't really
exists, cause is only emulating that, what it really does is use a part 
of the free space on your HD as RAM thought
cause it doesn't exists, is called virtual, "yeah but why does my 
machine goes slower than the other if both have 
physical memory?", well virtual memory has got, besides a lower 
transfer bus (the transfer bus is the speed in Mhz the
data is transfered from a place of the computer to the other) no 
inmediate access, this means that the RAM sends or 
recieve the data at the moment and has got a bus of minimum 66Mhz and a 
maximum of 800Mhz (only pentium-4 has
got a bus of 800Mhz, a kind of RAM called RRAM (Rambus Random Acces 
Memory) besides, RAM are chips and 
virtual memory (localized in the HD) are heads and cilinders, and as we 
all know chips are faster than head and 
cilinders. well that is what RAM is
BIOS: the bios is a little chip localized in the Mother Board, it tells 
the machine who it is and what date it is also
SLOTS & PLUGS: these are places where you plug every single card, 
component or cable in your machine, these
are localized in the Mother Board
GRAPHIC CARD: there are two kinds, the card itself (is plugged into a 
slot in the mother board) and integrated in the 
mother board (is the pure graphic processor, without condensors and all 
that stuff), these cards are uses in all 
the computers, this is so we can see images like icons, or the windows 
desktop and all those things, in other words
any image to be seen is needed of a graphic card.
SOUND CARD: as equal as the graphic card are two kinds, the dard itself 
and integrated to the Mother Board, this is
needed to reproduce any sound on your machine, without sound card you 
can not hear any sound, "yeah but, what
about is i connect my speakers to the computer???" you can't, without a 
sound card you can not plug your speakers
in the computer.
HD (Hard Drive): this is where all the info and data you have is stored
CD-ROM: unit where youre ad CD's on your computer
FLOPPY DISK: where you read the diskettes
(mouse, keyboard and monitor are not listed cause we all now what that 
is, don't we??)
3.1 OS's (Operative Systems)
these things are usde to, as their name says, operate your machines, 
without them your machine is just a bunch of
microcircuits without any use.
3.1.1- Windows
This is the most famous OS in the world, and also the most hated one by 
us, hackers, why???, well it ahs got a lot of
errors, bugs and problems, besides you can not do almost anything with 
it cause they hide every single adavnced
option so the OS looks as they want it to look and not as you want it 
to, anyways, this OS is owned by microsoft,
it's first release was "windows", then "windows 3.1", "windows 3.11", 
"windows NT series (NT1, 2, 3 and 4)".
"windows '95", "windows '98", "windows '98SE (Second Edition)", 
"windows 2000 (supposed to be NT5)", 
"windows ME (Millenium Edition)" and "windows XP (eXPerience)", this OS 
is intended for people that doesn't
know a lot about computers.
