Final Exam Review Fall 2004: Define

What hardware, there isnt munch in the book about any?
Look on the lecture slides. Angela Liang
the process of encoding media into little bits is called digitizing
it is about turning things from continous to something that we can count and for the uses it is easier to manipulate, to replicate,to compress and to trasmit.

can anyone help me on #2

The use of "little bits" is a bit vauge. What are these little bits? Numbers maybe, Os and 1s? Kelly Lyons
A little help on number 2. Your computer has a processor, a hard drive, RAM, etc. What does each do? Why do we need them all? Check the lecture slides. There is some in formation in the slides on speed. Also check the book. There might be more information there as well. Kelly Lyons
i cant find the answer for #2 as well
Are you in section A or B? I remember specifically an entire lecture devoted to hardware in section A. Check your notes from class. Kelly Lyons
Refers to objects that you can actually touch, like disks, disk drives, display screens, keyboards, printers, boards, and chips. In contrast, software is untouchable. Software exists as ideas, concepts, and symbols, but it has no substance.

Books provide a useful analogy. The pages and the ink are the hardware, while the words, sentences, paragraphs, and the overall meaning are the software. A computer without software is like a book full of blank pages – you need software to make the computer useful just as you need words to make a book meaningful.
On test number one I answered the question "What is meant by digitizing media?" by saying: taking media such as pictures, sounds, etc. and encoding them into your computer. Once "digitized" on the computer, it is easier to mainpulate, reproduce, etc. them." –But don't put that, I got -10 for that answer, and it is pretty close to what is in the book.
digitizing media is breaking media into parts and encoding them into numbers, so it is easier to manipulate, store, share, etc
The -10 was becuase your definition doesn't mention the idea that encoding for the computer consists of making things countable, bits, or numbers. This is an important part of what digitizing media is. A picture taken with a polaroid is just colors mixed to create a picture. You cannot count the pixels of that picture, it is a continuous thing, whereas digitized media is countable. You are able to separate it into parts, and those parts are represented by numbers.
