Hello CS 1020 Microcomputer Systems students,

      http://www.cs.uni.edu/~jacobson/1020/

            is our home page and it has a new link:

     http://www.cs.uni.edu/~jacobson/1020/PERLquotes.html

     This link is to the 7 students PERL/CGI projects 
     that I have received so far.

     Check out the page to enjoy the quotes and ideas and photos from your
     classmates.  Also, check to make sure your name and link is there, 
     to make sure I have received your URL okay and posted it.

     Do not forget that there is a quiz on Tuesday, and a 4 question
     Hamming codeword assignment due on Tuesday too.

     The quiz will cover:

            1. Convert binary to decimal.

            2. Convert decimal to binary.

            3. Understand the number system enough to figure out a base 5 or
                base 4 or base 7 number, and 
                what its value is in base 10, Decimal.

            4. Hexadecimal (base 16).

            5. Basics of subnet masks for a class B network, octets, class A,
                B and C networks and IP numbers.

                Class A: w specifies the network, x,y,z is the host
                Class B: w.x specifies the network and y.z the host.
                Class C: w.x.y specifies the network and z the host.

                Class    First octet pattern
                  A          0xxxxxxx       0 through 127
                  B          10xxxxxx       128 through 191 (UNI is 134)
                  C          110xxxxx       192 through 223

               UNI is a class B network:  134.161.0.0 is the network 
                                                      address, when the
                                                      host bits are masked
                                                      with 255.255.0.0
                                                      class B mask.
               Class A mask:   255.0.0.0
               Class B mask:   255.255.0.0
               Class C mask:   255. 255.255.0

            6. History of computers from the four generations to ABC and 
                 ENIAC and some of the persons.

            7. Moore's law and doubling the number of transistors that
                can be placed on a single chip of silicon every 18 months or
                so.

            8. Hamming codewords.

            9. Please Do Not Throw Sausage Pizza Away.  OSI SEVEN layers.

           10. cd, ls, ls -l, using the > for output redirection and < for input
                  redirection, and using the | to PIPE the output of one UNIX
                  sunny command to be the input of another UNIX command.

                  pwd,    bc < bc.data,   ls > myFiles,
                  cd ..
                  finger | wc
  
                  finger PIPEoutputOf_fingerTOtheWordCountingcommand wc

                  finger |  wc

     Next week, besides the 25 minute quiz, we will spend quite a bit of time
        on Adobe Fireworks and on Adobe Photoshop on Tuesday 
        and on Thursday.
