Web Hosting - Bandwidth and Server Load, What's That?
Two key performance metrics will impact every web site owner sooner or later: bandwidth and server load.
Bandwidth is the amount of network capacity available, and the term actually covers two different aspects. 'Bandwidth' can mean the measure of network capacity for web traffic back and forth at a given time. Or, it sometimes is used to mean the amount that is allowed for some interval, such as one month. Both are important.
As files are transferred, emails sent and received, and web pages accessed, network bandwidth is being used. If you want to send water through a pipe, you have to have a pipe. Those pipes can vary in size and the amount of water going through them at any time can also vary.
Total monthly bandwidth is a cap that hosting companies place on sites in order to share fairly a limited resource. Companies monitor sites in order to keep one site from accidentally or deliberately consuming all the network capacity. Similar considerations apply to instantaneous bandwidth, though companies usually have such large network 'pipes' that it's much less common for heavy use by one user to be a problem.
Server load is a more generic concept.
It often refers, in more technical discussions, solely to CPU utilization. The CPU (central processing unit) is the component in a computer that processes instructions from programs, ordering memory to be used a certain way, moving files from one place to the next and more.
Every function you perform consumes some CPU and its role is so central (hence the name) that it has come to be used as a synonym for the computer itself. People point to their case and say 'That is the CPU'. But, the computer actually has memory, disk drive(s) and several other features required in order to do its job.
Server load refers, in more general circumstances, to the amount of use of each of those other components in total.
Disk drives can be busy fetching files which they do in pieces, which are then assembled in memory and presented on the monitor, all controlled by instructions managed by the CPU.
Memory capacity is limited. It's often the case that not all programs can use as much as they need at the same time. Special operating system routines control who gets how much, when and for how long, sharing the total 'pool' among competing processes.
So, how 'loaded' the server is at any given time or over time is a matter of how heavily used any one, or all, of these components are.
Why should you care?
Because every web site owner will want to understand why a server becomes slow or unresponsive, and be able to optimize their use of it.
When you share a server with other sites, which is extremely common, the traffic other sites receive creates load on the server that can affect your site. There's a limited amount you can do to influence that situation. But if you're aware of it, you can request the company move you to a less heavily loaded server. Or, if the other site (which you generally have no visibility to) is misbehaving, it's possible to get them moved or banned.
But when you have a dedicated server, you have much more control over load issues. You can optimize your own site's HTML pages and programs, tune a database and carry out other activities that maximize throughput. Your users will see that as quicker page accesses and a more enjoyable user experience.
Explaining How Credit Scores are Used in the Hiring Process You might be wondering why credit scores are used in hiring processes. While you may have never heard about it, it is actually a more common practice than you might think. Companies and institutions such as banks, universities, retail stores, financial institutions across the United States use credit scores to determine whether an applicant is good for the open position or not. Even though you might think that this is illegal, it is not. In general, it is a legal undertaking for companies to look at your credit score. This is yet another reason why you should make sure that your credit scores are good and up to date. So why would they be using your credit information in a hiring process? For some of these companies, employees will be exposed to a lot of money and have a financially responsible position. Your credit information can actually help them determine whether you are a financially responsible person or not. Companies think that if you cannot handle your own money, why you would be qualified to handle their money? On the one side, if you think about it, it is a very valid thought. On the other side, the credit history will not tell the company how you might have gotten all the debt. What if one of your family members is really badly sick or a similar situation? In this case, you have not been irresponsible with your money, but you saved a family members life. You might have been willing to take on all this debt and then work from there. Sometimes numbers are just not an accurate representation of your life. Companies that do use your credit are not only determining whether you can handle money, in some instances they use it as an indicator for your character. It will tell them if you are responsible with your money and finances you are a responsible person. A person that will not be tempted by money or certain situations in a workplace is a person they can securely trust with their funds, their tasks or their great projects. One thing is for sure, the company needs to let you know that they are going to check your credit history in their hiring process and they also need to let you know what they are checking for. The criteria they are looking is the criteria they have to tell you about before you give them the permission. Unless they tell you and have a signature of permission from you, they are not allowed to check and use your credit history. If they miss these above mentioned steps, you do have a case in you hands that you can bring to the court. In some instances, some of the people that were not told about the credit check and have been denied have had a good case in their hands. But as with so many things in life in the United States it pays off to have a good credit history and such a check will not ruin your career moves. Check your credit history every year since once a year the big credit companies do have to give you a free credit report. In the case that you find any wrong or dubious items on your account go ahead and dispute them. Oftentimes companies might just have put a claim against your account that is not really caused by you. Why do companies do that? Money has caused many bad things in the world and a company that wants their money back is going to run after any lead they have. Therefore disputing your case and putting your credit score back to normal can be an essential part in your application and hiring process with some companies. Networking Ideas to Land a Job You Want Finding a new job is always a chore, especially if you are looking for your ideal job. While all jobs have pros and cons, finding employment that you enjoy or feel strongly about can greatly improve your job satisfaction. There are many ways to network and find the job you want. One of the biggest ways to make connections is to volunteer or find an internship. If you have not been able to land a permanent position in the career of your choice, apply for internships or offer your services for free. This is an ideal way to get your foot in the door and since the employer will already be familiar with you, it increases your chances of being hired when an opening arises. Meet people in the field you want to be in. If there are conferences or organizations that members who work in your desired field join, see about getting a membership or attending. Networking within your field of choice can build connections that blossom in the future. Take a lesser position at the company you want to work at. If you want to be a manager but are offered a customer service position, take the customer service position. Management roles are less stressful when you know what the company expects from you. Watch and learn the ins and outs of being a manager at that particular company. After you have some experience under your belt, apply for the next opening. Ask around. Most job openings are not posted anywhere. Finding openings is typically more about inquiring than finding posting. If you are eager to be a part of a company, e-mail your resume to the Human Resources department and see what type of hits you get. Stop by local companies and inquire in person and leave a copy of your resume if there are openings. Most employers are using the Internet to find new employees. Even if the position they are hiring for is not posted online, searching through posted portfolios is commonplace. The best way to get noticed is to have a concise portfolio that goes into detail about past work experience and your future career goals. Before you make it to an interview, the employer should already have a good idea about whom you are. Having a web presence is essential to job-hunting these days. Many employers are using e-mail and electronic submissions to screen employees. With that in mind, you need to be Internet savvy. Brush up on Internet skills, learning the tricks and trades of using the web as a way to seek out the best jobs. Purchase a domain and post your portfolio there. Be sure to show versatility, accomplishment and organization in your portfolio. Also if you choose to use social or networking sites represent yourself in a positive light. Be sure to keep your portfolio updated even when you are not actively looking for work. An interested employer could choose to contact you based on your updated portfolio. Be open to relocating. Search through Internet job postings for other states. Leaving your hometown might be difficult but the job of your dreams may be out there somewhere. Pack up and move to a more economically viable area and mingle with the populous. Make your employment intentions known without seeming desperate for a job. No matter what type of job you have been dreaming of, there are numerous ways to get that position. The key to pinning down, and getting the job you desire is to never give up. If you have been on the job hunt for two years without any success, do not give up. |
