- When an MS-DOS computer is first turned on it begins reading the hard disk
drive by reading the master record located at track 0, head 0, sector 1 or, if

The Model 1 came with 4Kb RAM standard. The built in Basic, called Basic
Level 1, was extremely limited. It had only 26 possible variables, labelled
A-Z of course, and one and only one integer array variable, called A(). The
monitor was basically an RCA TV with the tuner removed. Storage was on
cassette tape. Most Model 1s were upgraded to 16Kb and Level 2 Basic.
Additional expandability was gained through the Expansion Interface. This fair
sized box connected to the back of the Model 1 via a short ribbon cable. The
monitor then sat on top of the Expansion Interface. With an Expansion
Interface, you could add additional memory, control serial devices, use two
tape decks instead of just one, and control up to four floppy drives.

- If I record my mp3 music files on a CDR recordable CD as data files I can
get about 240 files per CD. If I play these on my computer with an mp3 player
they will play beautiful music for about ten hours. However, if I record
these same files on the same CD as music to be played with a CD player I can
only get about 1/10 as many which will play for about one hour. Why the
difference?

two computers were in two different buildings about 250 feet apart. I ran a

- The recent Sircam virus selects a file at random from an infected computer
and appends it to the virus which is then emailed as an attachment to a random
email address found on the infected computer. I have received 30 or 40 of
these emails. At first I simply deleted them as I do all unknown or
unsolicited email. Then I thought it might be interesting to look at some of
the files sent from infected computers. I found an employment contract
between a church in Lexington, Kentucky and its minister, an order for over
$42,000 worth of construction equipment, and a love poem. Then I quit wasting
my time and went back to deleting the emails. Most people are either ignorant
of email viruses and open them, infecting their computer, or are very scared of
viruses and will not touch them but delete them immediately. How was I able
to look at the content of a virus infected email attachment without infecting
my computer? Your answer does not require the specific program used (you
wouldn't know that), but simply a discussion of how a virus infects computers
and how it can be examined and analyzed.
