72- 1 inch, 36- 0/5 inch, 11-1-0. 5=9 1/2 (9. 5)/0. 5=19 line. Q: how many items can you represent w. 1 bit? (2) Convert the binary 1011 to decimal (1+2+8=11) Connected: computer is on all the time and connected to the internet. Always available: since it never gets turned off, your website will always be available. Well maintained: the people running the servers will take care of security and computer maintenance issues. We will use 2 different western web servers panther. uwo. ca (poster assignment) publish. gaul. csd. uwo. ca (web & major assignment) Assume for each pixel we have 1 bit to represent the color. 1 bit can hold either 0 or 1. Thus 1 bit allows for 2 colors, usually black and white (21 2) How many can 2 bits hold? (4: black, dark grey, light grey, white) Rgb (amount of red, green, blue) decimal number.
