Why is Linux not affected by computer viruses?

Linux (and other unix-like systems) were designed from the group up to be secure and allow secure multi-user access and networking. The reason why the Microsoft Windows family of operating systems have so many viruses is that it was originally designed as a single-user system and much of the security has been bolted on as an afterthought. This means that many more (and more severe) holes will exist.
There are actually viruses for linux, but they are generally far less effective.
virus is a program, it must have previledge to do nasty stuffs.

It is no doubt linux has virus, but when you running your linux as a normal user the virus cannot do anything bad.
If you run Linux as root (the equivaleng to Windows administrator), linux will be vulnerable to virus too.
By default installation, Windows XP creates a user which has administrator previledge, while Linux creates a user which has a normal (restricted) user previledge. This is the fundamental differences, since many Windows applications expect administrator previledge it is very hard to use Windows as a normal user. While most Linux applications are designed to run under normal user.

The Most Popular Operating System in the World

What is the world's most widely used operating system? It's not Windows, Unix or Linux, but ITRON, a Japanese real-time kernel for small-scale embedded systems. ITRON runs onmobile phones, digital cameras, CD players and countless other electronic devices.
ITRON emerged as an ambitious Japanese initiative known as The Real-time Operating system Nucleus (TRON). Launched in 1984, TRON was designed to replace disparate computer systems with a unified, open architecture for a "total computer environment."
Its ultimate goal was to create "highly functionally distributed systems" in which all system components are connected to a real-time network. Professor Ken Sakamura, spiritual father of TRON, conceived the project as a social infrastructure akin to the electrical power grid or water supply system.

Linux Alliance
This alliance between TRON and Linux could put more pressure on vendors of proprietary embedded software. Proprietary software is costly -- vendors usually charge royalties for each microprocessor running the software -- and licensing terms are often restrictive. Moreover, nearly all of the giants in the consumer electronics industry are rallying around open-source solutions.

50 Common Interview Questions and Answers

50 Common Interview Questions and Answers
1. Tell me about yourself:
The most often asked question in interviews. You need to have a short statement prepared
in your mind. Be careful that it does not sound rehearsed. Limit it to work-related items
unless instructed otherwise. Talk about things you have done and jobs you have held that
relate to the position you are interviewing for. Start with the item farthest back and work up
to the present.
2. Why did you leave your last job?
Stay positive regardless of the circumstances. Never refer to a major problem with
management and never speak ill of supervisors, co-workers or the organization. If you do,
you will be the one looking bad. Keep smiling and talk about leaving for a positive reason
such as an opportunity, a chance to do something special or other forward-looking reasons.
3. What experience do you have in this field?
Speak about specifics that relate to the position you are applying for. If you do not have
specific experience, get as close as you can.
4. Do you consider yourself successful?
You should always answer yes and briefly explain why. A good explanation is that you have
set goals, and you have met some and are on track to achieve the others.
5. What do co-workers say about you?
Be prepared with a quote or two from co-workers. Either a specific statement or a
paraphrase will work. Jill Clark, a co-worker at Smith Company, always said I was the
hardest workers she had ever known. It is as powerful as Jill having said it at the interview
herself.
6. What do you know about this organization?
This question is one reason to do some research on the organization before the interview.
Find out where they have been and where they are going. What are the current issues and
who are the major players?
7. What have you done to improve your knowledge in the last year?
Try to include improvement activities that relate to the job. A wide variety of activities can
be mentioned as positive self-improvement. Have some good ones handy to mention.
8. Are you applying for other jobs?
Be honest but do not spend a lot of time in this area. Keep the focus on this job and what
you can do for this organization. Anything else is a distraction.
9. Why do you want to work for this organization?

50 Common Interview Questions and Answers
This may take some thought and certainly, should be based on the research you have done
on the organization. Sincerity is extremely important here and will easily be sensed. Relate
it to your long-term career goals.
10. Do you know anyone who works for us?
Be aware of the policy on relatives working for the organization. This can affect your answer
even though they asked about friends not relatives. Be careful to mention a friend only if
they are well thought of.
11. What kind of salary do you need?
A loaded question. A nasty little game that you will probably lose if you answer first. So, do
not answer it. Instead, say something like, That's a tough question. Can you tell me the
range for this position? In most cases, the interviewer, taken off guard, will tell you. If not,
say that it can depend on the details of the job. Then give a wide range.
12. Are you a team player?
You are, of course, a team player. Be sure to have examples ready. Specifics that show you
often perform for the good of the team rather than for yourself are good evidence of your
team attitude. Do not brag, just say it in a matter-of-fact tone. This is a key point.
13. How long would you expect to work for us if hired?
Specifics here are not good. Something like this should work: I'd like it to be a long time. Or
As long as we both feel I'm doing a good job.
14. Have you ever had to fire anyone? How did you feel about that?
This is serious. Do not make light of it or in any way seem like you like to fire people. At the
same time, you will do it when it is the right thing to do. When it comes to the organization
versus the individual who has created a harmful situation, you will protect the organization.
Remember firing is not the same as layoff or reduction in force.
15. What is your philosophy towards work?
The interviewer is not looking for a long or flowery dissertation here. Do you have strong
feelings that the job gets done? Yes. That's the type of answer that works best here. Short
and positive, showing a benefit to the organization.
16. If you had enough money to retire right now, would you?
Answer yes if you would. But since you need to work, this is the type of work you prefer. Do
not say yes if you do not mean it.
17. Have you ever been asked to leave a position?
If you have not, say no. If you have, be honest, brief and avoid saying negative things
about the people or organization involved.
18. Explain how you would be an asset to this organization
You should be anxious for this question. It gives you a chance to highlight your best points
as they relate to the position being discussed. Give a little advance thought to this
relationship.
19. Why should we hire you?
Point out how your assets meet what the organization needs. Do not mention any other
candidates to make a comparison.

50 Common Interview Questions and Answers
20. Tell me about a suggestion you have made
Have a good one ready. Be sure and use a suggestion that was accepted and was then
considered successful. One related to the type of work applied for is a real plus.
21. What irritates you about co-workers?
This is a trap question. Think real hard but fail to come up with anything that irritates you.
A short statement that you seem to get along with folks is great.
22. What is your greatest strength?
Numerous answers are good, just stay positive. A few good examples:
Your ability to prioritize, Your problem-solving skills, Your ability to work under pressure,
Your ability to focus on projects, Your professional expertise, Your leadership skills, Your
positive attitude .
23. Tell me about your dream job.
Stay away from a specific job. You cannot win. If you say the job you are contending for is
it, you strain credibility. If you say another job is it, you plant the suspicion that you will be
dissatisfied with this position if hired. The best is to stay genetic and say something like: A
job where I love the work, like the people, can contribute and can't wait to get to work.
24. Why do you think you would do well at this job?
Give several reasons and include skills, experience and interest.
25. What are you looking for in a job?
See answer # 23
26. What kind of person would you refuse to work with?
Do not be trivial. It would take disloyalty to the organization, violence or lawbreaking to get
you to object. Minor objections will label you as a whiner.
27. What is more important to you: the money or the work?
Money is always important, but the work is the most important. There is no better answer.
28. What would your previous supervisor say your strongest point is?
There are numerous good possibilities:
Loyalty, Energy, Positive attitude, Leadership, Team player, Expertise, Initiative, Patience,
Hard work, Creativity, Problem solver
29. Tell me about a problem you had with a supervisor
Biggest trap of all. This is a test to see if you will speak ill of your boss. If you fall for it and
tell about a problem with a former boss, you may well below the interview right there. Stay
positive and develop a poor memory about any trouble with a supervisor.
30. What has disappointed you about a job?
Don't get trivial or negative. Safe areas are few but can include:
Not enough of a challenge. You were laid off in a reduction Company did not win a contract,
which would have given you more responsibility.
31. Tell me about your ability to work under pressure.

50 Common Interview Questions and Answers
You may say that you thrive under certain types of pressure. Give an example that relates
to the type of position applied for.
32. Do your skills match this job or another job more closely?
Probably this one. Do not give fuel to the suspicion that you may want another job more
than this one.
33. What motivates you to do your best on the job?
This is a personal trait that only you can say, but good examples are:
Challenge, Achievement, Recognition
34. Are you willing to work overtime? Nights? Weekends?
This is up to you. Be totally honest.
35. How would you know you were successful on this job?
Several ways are good measures:
You set high standards for yourself and meet them. Your outcomes are a success.Your boss
tell you that you are successful
36. Would you be willing to relocate if required?
You should be clear on this with your family prior to the interview if you think there is a
chance it may come up. Do not say yes just to get the job if the real answer is no. This can
create a lot of problems later on in your career. Be honest at this point and save yourself
future grief.
37. Are you willing to put the interests of the organization ahead of your own?
This is a straight loyalty and dedication question. Do not worry about the deep ethical and
philosophical implications. Just say yes.
38. Describe your management style.
Try to avoid labels. Some of the more common labels, like progressive, salesman or
consensus, can have several meanings or descriptions depending on which management
expert you listen to. The situational style is safe, because it says you will manage according
to the situation, instead of one size fits all.
39. What have you learned from mistakes on the job?
Here you have to come up with something or you strain credibility. Make it small, well
intentioned mistake with a positive lesson learned. An example would be working too far
ahead of colleagues on a project and thus throwing coordination off.
40. Do you have any blind spots?
Trick question. If you know about blind spots, they are no longer blind spots. Do not reveal
any personal areas of concern here. Let them do their own discovery on your bad points. Do
not hand it to them.
41. If you were hiring a person for this job, what would you look for?
Be careful to mention traits that are needed and that you have.
42. Do you think you are overqualified for this position?
Regardless of your qualifications, state that you are very well qualified for the position.

50 Common Interview Questions and Answers
43. How do you propose to compensate for your lack of experience?
First, if you have experience that the interviewer does not know about, bring that up: Then,
point out (if true) that you are a hard working quick learner.
44. What qualities do you look for in a boss?
Be generic and positive. Safe qualities are knowledgeable, a sense of humor, fair, loyal to
subordinates and holder of high standards. All bosses think they have these traits.
45. Tell me about a time when you helped resolve a dispute between others.
Pick a specific incident. Concentrate on your problem solving technique and not the dispute
you settled.

Emphasize benefits to the organization. Things like, determination to get the job done and
work hard but enjoy your work are good.

negative feelings.
49. Tell me about the most fun you have had on the job.
Talk about having fun by accomplishing something for the organization.
50. Do you have any questions for me?
Always have some questions prepared. Questions prepared where you will be an asset to
the organization are good. How soon will I be able to be productive? and What type of
projects will I be able to assist on? are examples.

fire wall

Use a Firewall
A firewall is a piece of software or hardware that sits between your
computer and the internet and only allows certain types of things to cross
the wall. For example, a firewall may allow checking email and browsing
the web, but disallow things that are commonly not as useful such as RPC
or "Remote Procedure Calls". In fact, it's vulnerabilities in RPC that
allowed for one of the more recent worms to propagate.
What's a firewall, and how do I set one up?
Viruses like the Sasser worm can be prevented simply by using a good
firewall. What's a firewall? Well, in your car it's the "wall" of metal behind
the dashboard between you and the engine that prevents engine fires
from roasting you and your passengers.
A firewall for your computer is much the same - it's to keep you from
getting burned.
A firewall's purpose is very simple: to block or filter certain types of
network traffic from reaching your computer. What do I mean by "certain
types"? There are things you want to get like the pages of web sites you
visit or the software you might download. And then there are other things
you might not want like people accessing your computer remotely or
viruses and worms infecting your machine.
A firewall knows the difference.
Firewalls are also usually configurable; they can allow you to say "this
kind of connection from the outside is OK". A good example is Remote
Desktop. A firewall will by default prevent it from working. But you can
also configure the firewall to allow that type of connection to come
through. That way you would be able to access your computer from
another, across the room, or across the internet. But other types of traffic
like viruses are still blocked.
Some firewalls will also monitor outgoing traffic for suspicious behavior.
One characteristic of many viruses is that once you're infected they
attempt to establish connections to other computers to spread. Many
software firewalls will detect and either warn you or simply prevent it.
