For the programming exercise (part ii) you are to turn in: • a single plain text file containing all your scheme source code. • a single text file named readme1.txt containing your name and any relevant information about your program (known bugs, compilation or operating anomalies, or instructions, etc). • a single file containing the outputs of several test runs of the program demonstrating that the program works in all reasonable cases. i will run your programs using scheme. • if your file is unreadable, or i cannot compile and execute your program, i will send you an email and you will have 24 hours to provide me with a working copy (normal late penalties apply). part i: written exercises. these are from the problem sets from the text (version 11 and version 10). 1. text, page 298 problem set #2 (p314 for version 10). - 1 pt 2. text, page 299 problem set #13 (#14 on p314 for version 10). - 1 pt 3. text, page 326 problem set #9. follow the format of the example given.

Data is processed, stored, and transmitted as a series of 1s and 0s. each 1 or 0 is called a(n) . a series of eight 0s and 1s, called a(n) , represents one character—a letter, number, or punctuation mark. data becomes when it is presented in a format that people can understand and use. digital signals are represented by two different , such as +5 volts and +.2 volts. digital data can also take the form of light and dark spots etched onto the surface of a cd or the positive and negative orientation of particles on the surface of a hard disk. data consists of numbers that might be used in arithmetic operations. it can be represented digitally using the number system. data is composed of letters, symbols, and numerals that are not used in arithmetic operations. computers represent this type of data using , ebcdic, unicode, or utf-8. data is quantified using terms such as or kibibyte (1024 bytes), and prefixes such as or mebi (1,048,576), and giga or (1,073,741,824). to reduce file size and transmission times, digital data can be compressed. compression provides the means to compress data and reconstitute it into its original state. compression throws away some of the original data during the compression process. compressed files usually have at the end of the file name and are represented with special icons. these files have to be or unzipped before you can view the data they contain.

Every telecommunication setup uses two devices: one device to transmit data and one device to receive data. which device transmits frequencies to mobile phones? towers transmit frequencies to mobile phones.
