Expanding and Extending USB

Expanding and Extending USB

USB (Universal Serial Bus) is a low cost interface connection. It is now the most common computer connection with many devices such as keyboards, printers and digital cameras using it as standard. As the number of compatible devices has grown the need to easily access them has also increased.

This has meant many users now need to expand and extend the USB connectivity of their laptop or desktop computer. Expanding allows devices to be shared, split and accessed by more than one computer or enabling a computer to connect to multiple USB devices at the same time. Expanding overcomes the problems of the limited number of USB ports often supplied with modern computers, especially smaller laptops and netbooks.

Extending increases the distance USB signals can be sent so a computer doesn’t have to be closely situated to the peripheral. This combats one of USB’s major limitations in that the standard maximum recommend length for a USB cable is 5m due to performance restrictions. However, for some applications for example interactive whiteboard installations, 5m is not always enough so signals need to be extended.

The most common method of expanding USB is through the use of simple USB hubs. Hubs allow multiple USB peripherals to be connected to one USB port. Hubs in turn connect to a host computer transmitting all connecting signals to it. The problem of port congestion is then solved as hubs generally have anything from 2 to 8 ports. Hubs are commonly free standing but are also built into devices such as monitors. USB switches expand peripheral connectivity by allowing them to be shared with multiple computers. They are a cost effective solution especially useful for devices which need to be accessed by more than one computer, such as printers.

They eliminate the need for duplicate devices and multiple cables. Switches alternate between computers as the users decide who has access to the equipment at that particular time. USB sharing hubs combine the functionality of both a hub and a switch and can serve multiple USB devices between a number of computers at the same time. Just like switches, sharing hubs are ideal for larger, more expensive equipment that needs to be accessed by more than one person at a time, but with the capability that allows users to do this simultaneously.

As with expanding, extending USB can also be achieved using a number of methods. A simple way of extending USB is by using extension cables. USB extension cables are useful for extending devices over shorter distances and typically max out at around 3m in length. The ‘plug and play’ capability of extension cables makes them a simple and easy to use solution. They work with both smaller and larger devices such as card readers and printers. USB extension cables are ideal for use with wirelss dongles or with products that have built-in USB cables.

A simple, cost effective way to extend USB over very long distances is by using Cat.5 USB Extenders. As their name implies, these devices use standard Cat.5 Ethernet patch cable to make the long distance connection. A transmitter is connected to a computer via its USB port while a receiver connects to the USB peripheral at the opposite end. The two units are then connected using Cat.5 cable. Commonly used with devices such as interactive whiteboards, extenders are a great solution for connecting devices further away from a host computer than an extension cable would allow. Distances of up to 50m can be achieved; however, USB 2.0 is not usually supported so devices are limited to USB 1.1 performance of up to 11Mbps. Cat.5 USB Extenders are probably the cheapest and easiest solution for connecting a USB device and host computer over great distances.

Perhaps the ultimate form of USB extension is USB over IP servers which allow USB devices to be connected to a network. Equipment such as a standard USB printer can be transformed into a shared network device as the server provides an interface between the device and a network. It simply connects the device to a network via Ethernet so the device can be used by anyone on the network wherever they are in the world!

Computer Backup Solutions - All Systems Go?

Computer Backup Solutions - All Systems Go?
The subject of computer backups has always been a topic of importance when it comes to preserving the data on your computer. These days there are more options available to you in this arena, which can be both a help and a hindrance. On one hand, having more options is helpful because better solutions have been brought to the marketplace from which you can now choose to fit your needs. A hindrance exists in that the multitude of choices might scare off users and cause them to avoid the issue altogether, which can have a disastrous ending.
It does not have to be complicated nor time consuming, so there is no good reason not to tackle backing up your computer.
The PhilosophyWe all know that backing up can preserve the information that is stored on your computer, but how far do you take your backup philosophy? It depends on what you can ‘afford’ to lose.
To one computer user, just backing up periodically will suffice. The thought here is that if you lose your data, you can restore it apart from your operating system, and the time that this takes is not a critical consideration. Many home users fall into this category. It makes sense as long as you are not dependent upon your computer for time-sensitive applications and tasks and/or for accessing and retrieving data relative to finances, etc.
To another user this philosophy is not enough. Topeng Those who depend on their data and computer for more than just casual personal computing understand that if a hard drive fails, their business is down until they can get it back up and running again. Home users who store irreplaceable photographs and home video on their computers will also fall into this category. A more comprehensive backup plan is recommended to help recover from disasters in a timely fashion.
Computer Backup OptionsThere are several ways to tackle backups of your important data:Built-in operating system options. Microsoft Windows operating systems provide built-in back up capabilities that allows you to back up your documents or files onto external media. Beginning with Windows XP and its Automated System Recovery feature, each unik successive Microsoft desktop operating system includes the capability to help recover your entire hard drive if necessary. These backup solutions are reliable and provide a built-in way for you to back up your data without having to buy an additional program to do so.
Manual copying onto external devices. You can always resort to the old stand-by method of backing up by manually copying your data onto an external hard drive, USB memory stick or other external device such as a recordable CD, DVD or even a floppy drive if you have one. This is cumbersome, but if you do not have a lot of files, it may be an acceptable solution for you. The pitfalls with this method are that if you have multiple files, you have to make sure you get all of them, and you may need numerous target media to save all of your files to.
Online options for backing up over the Internet. The newest option in computer data backup solutions is provided by online companies that enable backup and restoration of your documents and files over an encrypted high-speed Internet connection to any PC. A small background application backs up and transfers your files to a hosted storage area in a remote datacenter when your computer is idle; however, this is not a comprehensive disaster recovery solution for your entire hard drive. This solution works best when targeted at protecting individual files and documents on a PC or a Mac, and is generally a subscription-based service for which you pay a monthly fee for use.
Making an image of your hard drive. This is a more comprehensive backup and disaster recovery solution generally performed by technically savvy computer users. This option includes using 3rd-party programs to make an image of your entire hard drive, which can then be “re-imaged” in case of catastrophic failure to a new hard drive, providing a hard drive disaster recovery plan. Using this solution, within a short period of time, you can be back up and running with ALL of your documents, settings, programs and EVERYTHING intact, as if the disaster never occurred.
The way to determine the best solution to fit your needs is to ask yourself how soon you need to be back up and running after encountering a disaster, and how much you are willing to pay. If you can wait several days, then a computer back up program might be right for you. If you need your data files immediately, and you have a second computer that you can copy them to, then an online solution might be the best way to go. Or finally, if your business depends upon your computer and its applications and data, then you must have a more comprehensive solution.

The Disadvantages Of Attending A University

The Disadvantages Of Attending A University

We have discussed some of the wonderful advantages that university life and educations present. However, we must in turn discuss some of the other disadvantages that are associated with university learning as well. While we discuss these you should keep in mind that they do not by any means indicate that you should give up on your higher education goals, only that you should view your educational process with realistic expectations.

When compared with the community college system the very first and most distinctive disadvantage that comes to mind is the high cost of upper education on the university level. Community colleges are simply more cost effective all around than universities. The costs go well beyond that money that would be spent on room and board making the tuition alone cost prohibitive in many cases. While there are many types of financial aid available to students the vast majority of college students in this country make ends meet through the use of student loans, which must be repaid at quite a hefty interest rate, in order to cover the costs associated with university educations.

Beyond the one obvious disadvantage there are a few other disadvantages that bear mentioning in this particular circumstance. First of all, universities do not have the small intimate classroom settings that literally set community colleges apart. In fact, for lower level course, most universities offer large auditorium classes that are taught by graduate students rather than professors and more often than not the students never get to know those who are charged with their education on more than a nod and smile while passing in the halls basis. This method for learning is considered by many to be exceptionally inferior and the statistics prove that students who go straight into a four-year college environment rather than going through a community college first are far less likely to complete their degrees.

If that isn’t enough of a disadvantage, many people find that the impersonal atmosphere of most universities is quite limiting when it comes to interaction with other students. The smaller classroom environments of community colleges invite interaction between the students in the class. An open line of communication within the classroom is greatly preferred to having so many students that no one gets a voice or the ability to voice their opinions or personal experiences when it comes to certain topics.

Another disadvantage to university life is the sheer size of university campuses. Community colleges tend to be much more compact. This means that students have a fairly decent chance of making it to all classes on time and without the worry of walking 2 miles in ten minutes. While this is great for physical fitness, missing the first ten minutes of class each week can limit the educational process that your university experience should be providing. It seems like such a small thing on one hand but when you are hauling around a day’s worth of textbooks and a laptop–that hike can be the thing that marines seem dubious about accomplishing.

While there are a few distinctive disadvantages to university life, the fact remains that graduation from a university is the single biggest way to increase your earning potential over the course of your lifetime. The amounts are by no means insignificant. I highly recommend whenever possibly that you attend community college for the first two years of your college education. Beyond that, I strongly urge you to consider the value that completing your education and getting a four-year degree can provide.

If you wish to build self-confidence, earning potential, and job security, there is no way of doing so that is superior to getting a four-year degree. It doesn’t matter where you are in life or your career; it is never too late to begin getting your education. There are so many things in the world that a good education will open your eyes to in addition to the doors of opportunity a four-year degree will open.
