Digital libraries provide to the user satisfaction of their needs and the things needed for the management, access, storage, and manipulation of various information stored in the collections of library materials which represent the ownership of the library. Even understanding the various users here too, can the end user, operator library, and also the ‘producer’ of information hard drive recover.
RAID is an acronym for “redundant array of independent disks.” It is a set of hard disks group together and access based on predefined settings to provide striping, data mirroring, or redundancy. You need world-class expertise for RAID 5 data recovery when a failure occurs due to a number of reasons. These reasons include data corruption, power surge, or removal of data format, virus attack, or reconfiguration of the RAID volume deliberate among other reasons.
If you suspect a failure in your RAID 5 array, it is important to not reboot the system because it can cause serious damage and system failures. If you hear unusual sounds or clicking sound, it is recommended to shut down rather than continue to run the drives fail because it can cause complete loss of your data. If you suspect damage or failed drive, a wise thing to do is to call a RAID 5 data recovery professionals who have more than a decade of experience in RAID 5 recovery more information.
Making Money With the Internet
Posted by este in Internet Marketing on November 9, 2011
The power of the Internet in modern times has allowed the average Joe on the street the ability to reach millions, probably now billions, of people from all over the world.
Over the last 2 decades we have gone from merely being able to send a typed message from one computer to another on the other side of the world, to being able to have a conversation with the person, seeing them on the screen in front of us using a webcam and it feeling like they are actually right there in front of you.
This, of course, has opened up the world of business in a staggering way. Not only are people now able to make money online and go into business for themselves more easily than ever before but also the potential market for already existing businesses has dramatically increased as they are now able to pretty much reach anyone with a computer and an internet connection to attain their custom.
Add to that the relatively recent advent of Internet on mobile phones and a business can contact almost any person on the planet with the right sort of advertising, in the right place, at the right time.
This has also revolutionized the ability for one to work from home. No longer do home based businesses have to rely on posting out catalogues in the hope that a customer might buy something from them, they can put their products on the internet for people to look at and speed the process up.
You also now have the ability to work from home, selling a product you will never see, to a person you don’t even have to meet or talk to.
A company that has capitalized on this idea is called Your Net Biz. It’s a business in a box. They give you all the training, resources and help via a mentor that you will ever need to make money online. One extra ingredient is needed though: you. You need to be willing to learn, to make mistakes and to be able to “bounce back” and see it as a learning experience. You need to be willing to put the effort in and reap what you sew; you get out what effort you put in, it is a business after all. I highly recommend giving it a go!
How Websites and the Internet Work
Posted by este in Internet and Businesses Online, Web Development on November 3, 2011
I want to give a very basic explanation of how websites and the internet work. I don’t want to get too technical but it does help to have a basic understanding before you build a website.
When you connect to the internet, you are joining a huge network of computers. You usually connect through your Internet Service Provider such at AT&T, Comcast, etc. Each time you connect, you are given a unique number that identifies you to the rest of the internet. This number is called an IP (internet protocol) address. It looks something like this: 109.74.105.149
Most of us have dynamic IP addresses which means that every time we connect, we get a new IP address. It may be a different number every time so it’s considered dynamic. We can access other computers by typing in their IP address in the address bar of our browser. Since most of us don’t remember numbers very well, we use domain names to translate to the IP address.
Each domain name is registered and stored online so that when someone types that domain name in their browser’s address bar, the name is looked up and translated to the correct IP address. This requires that the computer where the website lives have a static IP address meaning that the IP address has to be the same always. Your domain name can point to any computer with an IP address, so you can move your web site to another computer if you want, you just need to change where the domain points when you do.
Most ISP’s don’t allow you to have a static IP address or allow other computers to access your computer directly. So, most of us don’t have our websites on our own computers. The ISP doesn’t like it because it would create too much traffic on their services and slow all their other customers down. It’s also not a good idea because websites need to be up and running 24/7, so you would have to make sure that your computer was in top-notch condition, on all the time and that you never did anything else on it that might slow down the website. You would have to have battery backup in case the power went out and if a storm, earthquake, or other catastrophe occurred, your website might be history.
For those reasons, most of us ‘rent’ or ‘lease’ computer space for our websites. This renting or leasing is often called ‘hosting’. We pay others to use their computers to host our website for us. Usually these host computers are underground or in very secure data warehouses which are storm, earthquake, etc. resistant. They keep our websites as safe as possible and don’t use these computers for anything except hosting websites.
These host computers will have software called web servers installed to control access to our websites. The web server is responsible for delivering the correct web page that’s being requested, keeping statistics, keeping up with multiple websites, and much, much more. Since computers that are used to host websites all have this type of software, many times these computers are referred to as ‘Servers’.
Most of us have small websites and one computer is way more than we need to keep our website up and running. One computer can host many, many websites. For our small websites that don’t get an incredible amount of visitors, shared hosting is more than enough. In other words, we don’t have to rent or lease a whole computer for our website, we can just rent or lease enough space and bandwidth (the way they measure the traffic or visitors you have coming to your site) for your website. This is called shared hosting and can be very inexpensive.
Shared hosting has many websites on one copy of the server software. In other words, one instance of the server software can control many, many websites. We don’t have to have multiple server programs for each website. Just like you can have multiple documents in Microsoft Word. You don’t have to have a separate Microsoft Word instance for each document. For this reason, the settings in the server software will be used by each website. It’s not always possible to optimize settings for any one website without changing the settings for all the other websites. Most hosting companies don’t allow you to access the settings for shared hosting at all. Again, I’ve simplified things here a bit so that I don’t have to get too technical.
Sometimes we need to optimize those settings for our website. Or we need to do things that might slow all the other websites down that are running within the same instance of the web server. In these cases, and in many other cases, we might need our own dedicated instance of the web server. We can rent or lease this kind of hosting too. It’s often called VPS (Virtual Private Server) Hosting. It usually costs more than shared hosting because it requires more space and resources from the computer. But, you are still sharing the computer, because usually there are more than one VPS running on the same computer.
If your website is extremely big or has a lot of traffic or requires a lot of space for some reason or needs to be extremely fast, you will need a Dedicated Server. This means that you are the only one with websites on the computer. You can rent a computer and put one website or as many as you can fit on there, but you are the only one on the computer so you can set it up or change it however you want. This can be fairly expensive but well worth it if your website needs it.
So, when you type in a web address in your browser, your computer sends that web address to your ISP. Your ISP will send the domain name to a computer called a ‘Name Server’ which translates that domain name into an IP address. Your request for that web page is then sent to the computer at the IP address. The server software receives the request, finds the web page requested and returns it to your ISP, who sends it on to you.
If you have more than one computer connected to the internet at your home or office, then you have a device called a router which receives the request from your computer and then sends that request to the ISP. The ISP will send the response back to your router. The router will then direct the response back to the requesting computer. Again, this is a simplified version of what actually happens. There is really much more going on behind the scenes.
Hopefully, that gives you a big picture for why you need web hosting if you are going to have a website. It should also help you see why you might need a domain name as well.
