- The term computers is a very broad one, so
I'm going to limit the discussion to three topics only:
- Web Site Design, Computers
Viruses and 3D Design.In the following sections, you will find all the
- information necessary for a better
understanding of these subjects.
- Designing a web site could be an easy task if you follow the
- Find a serves provider. I mean, find a company which would
give you web space to save your page on.
I suggest XOOM.
They will give you your address and the address of the ftp server, ftp.xoom.com
in case you go with XOOM.
- Find an HTML editor. This program is used to design the
site. It is very similar to word editors.
I suggest MS FrontPage.
This is a very powerful program designed by Microsoft. I have provided the express version
of this program for you to download. It has most of the functions of the complete version.
In fact, I made my first site using the express version.
- Start designing your page and save it to your hard drive.
Remember that all the pictures used to design the page should be saved in the same
directory as the page it self. Also, you are going to need an image editor to modify the
images you want to use in your page.
I suggest Paint
Shop Pro as an image editor. You can download an evaluation copy of the program which
will function for 90 days.
- Find an ftp editor program. This program will allow you to
save your page to the server you picked in step one.
I suggest LeechFTP. After
downloading the program, use your ftp server address, ftp.xoom.com in case you go
with XOOM, username, and password to connect to the server.
- Locate the directory on your hard drive where you saved the
site. Select all the files and copy them to the server.
If you have decided to use LeechFTP, the middle part is
your hard drive directory. The right side of the program is the server directory. To copy
files from your hard drive to the server, select and drag the files to the right side of
the program, the server side.
- Now, use the address provided by the server company to
access your page using any internet browser.
In case of XOOM, it is http://members.xoom.com/username
- A virus is a piece of software designed and written to
affect your computer by altering
- the way it works without your knowledge or permission.
Computer viruses do not
- spontaneously generate: They must be written and have a
specific purpose. Usually a
- virus has two distinct functions:
- Spreads itself between files without your
- Implements the damage planned by the
- This could include erasing or damaging your computer.
There are different types of viruses; some
of them are:
- These are viruses that attach themselves to (or replace) .COM
and .EXE files. With
- this type of virus, uninfected programs usually become
infected when they are
- executed with the virus in memory. In other cases they are
infected when they are
- opened (such as using the DOS DIR command)
or the virus simply infects all of the
- files in the directory is was run from (a direct infector).
Boot Sector Infectors
- Both hard disk and floppy contain a boot sector.
This boot sector contains specific
- information relating to the formatting of the disk, the data
stored there and also
- contains a small program called the boot program (which
loads the DOS system files). It is the program that gets infected by viruses. You
get a boot sector virus by leaving an infected diskette in a drive and
rebooting the machine. When the boot sector program is read and
executed, the virus goes into memory and infects your hard drive.
Master Boot Record Infectors
- The first physical sector of every hard disk (Side Ø,
Track Ø, Sector 1) contains the
- disk's Master Boot Record and Partition
Table. The Master Boot Record has a small
- program within it called the Master Boot Program
which looks up the values in the
- partition table for the starting location of the
bootable partition, and then tells the
- system to go there and execute any code it finds. On floppy
disks, these same
- viruses infect the boot sectors.
- You get a Master Boot Record virus in exactly the
same manner you get a boot sector virus -- by leaving an infected diskette in a
drive and rebooting the machine. When the boot sector program is read and
executed, the virus goes into memory and infects the MBR of your hard drive.
- Multi-partite viruses are a combination of the
viruses listed above. They will infect both
- files and MBRs or both files and boot sectors.
These types of viruses are currently
- rare, but the number of cases is growing steadily.
- If you want a feel of it, you can download Nuke.zip on your
- in other words, I'm not responsible for any damage.
- This program is a virus generator.
- One of the most powerful programs for 3D design is 3D
Studio, so I'm going to use it
- as an example of the designing programs.
- The first step in designing in 3D is to visualize the object in its simplest
- example, a skyscraper is basically a rectangle. This will
ease the process of drawing
- the object. Once you draw the object, you have to chose the
light intensity and the
- camera's angle of view.
- Right: This is a snapshot
- of what you expect to
- see after drawing the
- object and placing the
- camera and lights. In
- this case the objects
- are a box and two
- swords placed over a
- rectangular base. Note
- that it dose not have
- any colors or textures,
- but these will be added.
- The second step is to apply the colors and textures to each object. For example, if
- we have a rectangle for a skyscraper, we will need a picture
of a skyscraper to apply
- to the rectangle as a texture. This will result in
transforming the rectangle to the
- skyscraper in the picture.
- Right: This is a snapshot
- of the final product. You
- can see that what used
- to be a rectangle is now
- a marble rock. Also, what
- used to be a rectangular
- base is now a piece of
- wood. Note that the angle
- of view and the intensity
- of the lights are up to the
- designer to determine.
- You can animate the object by simply moving the camera
around it. This is an example that I've made - select the format you want: Sword.fli or Sword.flc.
Also, I have included a zip file in the following link which has lots of 3D Images for you to enjoy.
- I will show you how to replace the Windows95 logo which
appears when you start your
- computer, the shutdown screen, and the waiting screen. The
first step is to get an
- image editor program such as CoolBar
Animator. Secondly, using the image editor
- program open the file C:\LOGO.SYS which is the startup
screen, C:\WINDOWS\LOGOS.SYS which is the waiting screen, and C:\WINDOWS\LOGOW.SYS which
is the shutdown screen. Make all the changes
- you want then hit the SAVE key. BOOM, you've just changed
the screens. Feel free to download my Startup, Waiting,
and Shutdown images. Remember to save each file in the appropriate
Click on the following link to download
FreeTel Personal Edition as a gift from me to you.
- In case you have any questions about 3D Studio, 3D MAX, MS
Visual Basic, MS
- Office, C Language, Quick Basic, AutoCAD, Windows95, MS DOS,
MS Front Page,
- or upgrading your computer, don't hesitate to contact me any time.
