We started with a series of questions regarding operating systems:
- What are the differences between the different types of OS's that there are? (different programs)
- Do you need and OS to make an OS? (don't know!)
- When connecting to another computer can you get all the information from one computer to another? (yes, but not automatically. Depends on the operating system)
- How much information can an OS hold? (complicated question: doesn't really hold information, but it can control information, have information programmed in to it, take up certain room in the computer, like the way Windows included Internet Explorer in previous versions. The less things the OS uses, the fewer resources it takes up within the computer. It can take up a lot of hard drive and it can use up a lot of RAM too.)
- How do you make an OS? (don't know! look it up!)
- What makes one OS more expensive than another? (market, supply and demand)
- In general, how expensive is it to install a new OS, as compared to upgrading/dating? (Depends, look it up!)
- What makes one piece of software more effective than another similar piece? (personal preference)
- What are the basic functions of an OS? (too complex to answer in this class)
- UBUNTU: Why no search box in Google Chrome? (different program for each browser)
- Is there an OS that is better for home computers? (depends on what you are doing, there are some OS specifically built for servers, for simple devices, etc)
- Are there any OS other than the ones we have covered? (yes, there are tons)
- Is a newer hard drive better than an old one that's been wiped clean? Even if the specs are the same? (tricky question, very possible that it could be better/worse, depending on a lot of factors)
- What does BIOS stand for? (Basic Input-Output System)
- What besides a computer is need to make an OS? (don't know)
- How does a computer translate between decimal numbers and binary? (codes for each letter, codes for each number)
- What pieces of hardware are necessary and what are optional? (great discussion question, do extra research: power supply, motherboard, memory (hard drive/ram), processor,
- Why do we need a BIOS? (basic input/output system = start-up sequence program before OS, software that is hardcoded in to the motherboard. You can reconfigure it, but it is hardwired in to the motherboard)
- Why is upgrading necessary? (not 100% necessary, helps with security
- Is there a program that helps you to create an OS? or do you need to know binary? (don't know for sure, probably written in a language called machine code, which is different)
- What makes the flavors of Linux different from each other? What are they? (there are a ton of them! Look them up and read about them.)
- What was the hardware called to uninstall and reinstall an OS? (???)
- How do you use binary with words? (codes for letters)
- Are certain OS better for certain programs? (issue of preference)
- How is video written to binary? (many types of formats, depends on how it is rendered, you can look it up and learn more)
- How is antivirus software made? (not 100% sure, but probably similar to a spell checker, programmed to look for certain things and then remove it)
A.J. proceeded to answer the questions that he knew the answers to, (but then there were some that he didn't know about). It was a long discussion, but we got a lot of our questions answered!
Virus Information:
Students were given a few minutes to look up information about their questions and then about various kinds of viruses. Each row had a different virus to research: worms, rootkits, phishing, trojan horse. We also took a few minutes to talk about how to evaluate sources on the net.
Worms
- can replicate themselves
- can travel from computer to computer w/o human interaction
- subclass of a virus
- file dependent and can be reproduced
Rootkits
- sneak in to system and make themselves an administrator and can control the computer for whatever they want
- you have to download it yourself
- attach to BIOS or other targets of basic system
- they hide within the system, sometimes cause erratic behavior
Phishing
- tricks you to get personal information out of you
- mimic original sites
- it is us that get fooled
Trojan Horse
- It is like a virus rootkit that looks like an innocent or useful program
- keyloggers, etc
- have to be deleted instead of cleared because it is a file attached to something else
- it appears to be doing something you want it to do, but it is really doing something else
How do you prevent these things getting on to your computer.
- Do not use Limewire.
- Don't download everything you see.
Research on individual questions:
- Carrie
- Different flavors of Linux: which is best?
- They can't tell you what is best for you, because it depends on your computer and on how you use your computer.
- Bronson
- For creating an operating system:
- Linux from Skratch is a program you can use to make your own flavor or app for Linux.
