3.) If the input 123.4 is read as a number, this means that the decimal representation of the number 123.4 is translated by the computer into its binary equivalent (a series of 1s and 0s). If the input 123.4 is instead read as a set of ASCII codes, this means the computer is treating each character (1, 2, 3, ., and 4) as a literal character. Each of these characters has an ASCII code (a number between 0 and 127). Each code is then translated by the computer into its binary equivalent.
4.) At their core, computers are just a series of switches that have two positions, on and off. Therefore, the binary system of 1s and 0s allows computers to represent rich information from our world using its switches, where 1 is on and 0 is off.
5.) Software is written to run properly on a particular operating system and processor. So software written to run on a Pentium II chip won't work on a PowerPC-based computer like a Macintosh unless a "platform independent" programming language like Java is use
6.) In addition to clock speed (MHz), the architecture of the processor and of the entire computer also determines speed.
7.) Since the mother board is the "heart" of the computer and everything is depended on the external and internal devices have to work together in order to run the hard drive smoothly.
8.) Symmetric Multiprocessing involves a multiprocessor computer architecture where two or more identical processors can connect to a single shared main memory. Most common multiprocessor systems today use an SMP architecture.
9.) RAM (Random Access Memory) provides the computer a place to store information until the processor is ready for it. So the computer can both write to and read from RAM. ROM (Read Only Memory) provides important information to the processor, but this information is stored permanently and cannot be changed.
