lab 1.1

1. Question - Computers are unique in that they are general-purpose devices. In other words,they 
were not designed for a very specific purpose, the way a watch is designed tokeep time and a dictionary is designed to provide definitions. 
As it turns out,however, computers can certainly both keep time and provide dictionarydefinitions. Name three other special-purpose devices or objects 
(not necessarilyelectronic) which do things that computers can also do with the appropriatesoftware and/or hardware.


DVD player - plays movies, windows media player - plays movies,videos and music
calculator - does math for you




2. Question - RAM and hard disks are both forms of data storage. How are they alike? Howare they different? 
In particular, discuss the relative advantages anddisadvantages of each.

RAM and hard disks both store data. But the thing that makes them different is in the way that they store. With RAM all your data will be lost or earased 
if the computer is to turn off. The hard disk serves as a permanent storage place for programs and files and is much cheaper. The advantages of Ram is that its much faster than the 
hard disk storage.



3. Question - Describe at least one non-computing example of hierarchical organization in the
real world—something like the geography example given in the lab.

School system or the government because they both branch off into different things.
