9. Discuss/review hexadecimal notation for Lab 3 exercise [30 to 45 minutes]
Explanation for why we learn binary and hex code
Each byte in memory (or on a disk) is the equivalent of one alphanumeric character (ABCabc1234$^&, etc.).
A byte has eight binary bits examples: 00000001 (decimal value 1) or 00001111 (decimal value 15).
There are 256 possible ways (2 to the 8th power) that you can arrange a string of eight "ones" and "zeros"
to form a byte of information. If you go to a website with a PC character map chart, for instance,
you'll see that each binary/decimal value between 0 and 127 has a different command or alphanumeric character
associated with it. (For instance, a capital letter "A" has a value of 65 (or 01000001). The values between 128 and 255
are reserved for special language alphabet characters and drawing boxes, as you can see in the Extended
Character chart at
So knowing a little bit about the relation between decimal numbering and binary numbering can make it easier
to understand how the computer turns strings of ones and zeros into executable commands and text that
you see on the screen.(30 minutes)
9. (Time permitting) Discussion of PC boot process, formatting a disk
- Examine PC Hardware identification sheet in LABS handout and see how many components you can identify.
- Read sections in PC1 handout on hardware vocabulary review and PC memory types. See how many vocabulary words you can define.
- Read "More DOS" section in PC1 handout.
- Complete the Lab 3 "Bits, bytes, and kilobytes" exercise in the LABS handout.
- Complete the "Exploring the System BIOS" lab in the LABS handout.
- Review CPU, Disk, Motherboard, and Operating System vocabulary in handout, using URL references as necessary.
- Review information on PC hardware components from URLs & handout material
- Preview URL links & handout material on PC troubleshooting.
