Firewalls can't protect very well against things like viruses or malicious software (malware). There are too many ways of encoding binary files for transfer over networks, and too many different architectures and viruses to try to search for them all. In other words, a firewall cannot replace security-consciousness on the part of your users. In general, a firewall cannot protect against a data-driven attack--attacks in which something is mailed or copied to an internal host where it is then executed.

Alternate Answer:
Properly configured firewalls can limit the propagation of worms - a form of malware.  Typically, firewalls are edge or parameter devices (separates network zones) and most viruses and malware targets end points (user workstations and servers).

There are 3 main uses for the static.
1. If you declare within a function:
It retains the value between function calls

2.If it is declared for a function name:
By default function is extern..so it will be visible from other files. if the function declaration is as static, it is invisible for the outer files

3.Static for global variables:
By default we can use the global variables from outside files If it is static global..that variable is limitied to with in the file

Start with the present and tell why you are well qualified for the position. Remember that the key to all successful interviewing is to match your qualifications to what the interviewer is looking for. In other words you must sell what the buyer is buying. This is the single most important strategy in job hunting.

So, before you answer this or any question it's imperative that you try to uncover your interviewer's greatest need, want, problem or goal.
To do so, make you take these two steps:
Do all the homework you can before the hr interview to uncover this person's wants and needs (not the generalized needs of the industry or company)

As early as you can in the interview, ask for a more complete description of what the position entails. You might say: "I have a number of accomplishments I'd like to tell you about, but I want to make the best use of our time together and talk directly to your needs. To help me do, that, could you tell me more about the most important priorities of this position? All I know is what I (heard from the recruiter, read in the classified ad, etc.)"

Then, ALWAYS follow-up with a second and possibly, third question, to draw out his needs even more. Surprisingly, it's usually this second or third question that unearths what the interviewer is most looking for.

You might ask simply, "And in addition to that?..." or, "Is there anything else you see as essential to success in this position?:

This process will not feel easy or natural at first, because it is easier simply to answer questions, but only if you uncover the employer's wants and needs will your answers make the most sense. Practice asking these key questions before giving your answers, the process will feel more natural and you will be light years ahead of the other job candidates you're competing with.

After uncovering what the employer is looking for, describe why the needs of this job bear striking parallels to tasks you've succeeded at before. Be sure to illustrate with specific examples of your responsibilities and especially your achievements, all of which are geared to present yourself as a perfect match for the needs he has just described.

A database index is a data structure that improves the speed of operations in a table. Indices can be created using one or more columns, providing the basis for both rapid random lookups and efficient ordering of access to records. The disk space required to store the index is typically less than the storage of the table (since indices usually contain only the key-fields according to which the table is to be arranged, and excludes all the other details in the table), yielding the possibility to store indices into memory from tables that would not fit into it. In a relational databasean index is a copy of part of a table. Some databases extend the power of indexing by allowing indices to be created on functions or expressions. For example, an index could be created on upper(last_name), which would only store the uppercase versions of the last_name field in the index. Another option sometimes supported is the use of "filtered" indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.

Here's what the resume advice company Resume Edge recommends as a sample answer to the question, "Where do you see yourself in ten years?"

In ten years, I endeavor to have refined my strategic and client relations skills. I intend to be a leading expert in estate planning. After having proven myself as a senior manager, I hope to help shape the strategic direction of estate planning services. I could do this in any number of official roles. The important thing is that I will continue contributing my abilities in a challenging and rewarding environment.

• While it is not usually a good idea to try to be a Jim Carey in an interview, depending on how things have gone and who you are dealing with, you might inject a little humour here and ask: "When do you expect to be promoted?" ....or "When are you moving on?... This could easily break the ice. Seriously, you can easily respond that you have no idea as you have no idea what you are capable of so far, although you know it is a lot. Therefore, you want to make sure you are open and flexible to whatever opportunites present themselves. If you actually know what you want to be when you grow up, you could offer to conduct a seminar on how to actuate that.

• You know when you come to that common situation where someone asks you "Where do you see yourself in five years?" Yea you should call a person on that because that question is silly! You have no idea where you'll be in five years nor should you worry. I mean how depressing can that question actually be? If someone asked me that question five years ago I wouldn't have predicted my life to be like this nor would I have wanted to say my life would be like this, I'm not saying I'm unhappy with my life necessarily its just that in a span of five years a persons likes and dislikes change, the people around them either disappear, reappear, or show up for the first time. The things you once loved could become something you hate or vice versa. Aspirations change and feelings lose their magic. Yes you can say what you'd like to see happen in five years but I'm pretty sure it won't and five years from now when you look back on yourself answering that question you'll probably no longer want the same things. There's always hope but no definite so all you can do is live life like you have those five years to look back on...

• When an interviewer asks this question, they're asking where you see yourself within a company. They don't want to hear you say, "Well, in five years, I will be married to a handsome European man, touring the South Pacific in our yacht with a maitai in my hand." They want something like, "Well, that will depend on my individual performance and on the opportunities I'm presented with, but ideally, I will be..." Even if you're going, "Yeah, like I'll be here in 5 years..." act like you will be. They don't want to hear you saying you'll essentially use them to get where you want, and the minute the opportunity is presented jump ship.
• Some might think that you should not tell the interviewer that you want to move up the ladder of success, because they will fear that you might replace them or move on to another job. However, most would recommend that you answer with just the opposite: that you do want to be successful. A good manager wants his employees to be successful and grow in their careers because that benefits the whole company. If they don't want this, you don't want to work for them. As for the actual standards of success and specific career paths, they are very different for different people and different industries. It is most important to show that you do want to be successful.
• Think educationally-- higher degree? certification? Think leadership-- at least one step up from where you are at now.

Where will you be in five years?

This is a very common job interview question. Think carefully about your plans. Really answer it for yourself, Where do you see yourself in five years? Where do you hope to be?

The interviewer is looking to find out a few things with this question. First, are you the type of person who plans ahead and sets goals? You should be. Second, do your goals match those of the company and the position? Your goals need to fit the career path for the job. They don't want to lose you in a year or two.
