Computer hardware storage

Computer hardware storage basically refers to the hard drive that is connected to the computer system. This is the main storage area of the computer and where all programs, files and the operating system run from. In recent years, partly due to an influx of content on the internet in addition to the increase of high-definition, which in my opinion account for the great need of memory, hard drives now come in capacities ranging from 160GB, on the low-end to terabyte ranges. Terabyte computer hardware storage is a memory capacity that is over 1,000 megabytes. Can you imagine the amount of content you can have on such a hard drive? Well believe it or not, these memory capacities are becoming an everyday norm. If you donít have one right now, believe me you, in a few years, you will have a couple of teras on your system.

The physical size of the hard drive however has not changed despite the high capacities that can be seen today. On the contrary, the drives have shrunk, thanks to the consumer need for miniaturized gadgets. We all want large capacities that one can carry around, it at all necessary anyway. Of course, this does not come cheap, the large the capacity, the more you will have to pay for it. When you are purchasing a hard drive, consider your future needs. In most cases, the size of your hard drive will be insufficient in a few years if not months. So try to see if you can get the largest capacities within your budget.

Today, computer hardware storage need not be physically located on your system. You have probably heard of cloud computing and terms related to that. If not, then sooner or later you will because that could well prove to be the future of data storage, in my opinion. Many companies have already implemented online storage solutions that are meant to cut back on expenses. Consumer services that are cheap and affordable like EMC Mozy and iBackup are a consumer-driven IT phenomenon that has even some corporates riding on. The truth is that online storage is picking up and will likely continue to do that. When computer hardware storage is immobile, many opt to have their documents, files and anything that can be digitized online. The ease of accessing this information from anywhere in the world does not need to be over-emphasized. Online storage is big, and will get bigger. Donít be left behind, ride the wave.

Computer training courses

Gain Valuable Skills Via Computer Training Courses

Most of today’s high school and college students are completely comfortable around computers. Even without taking formal classes in how to use these machines, modern youth are likely to know a lot more about computing than people two or three times their age. This is not surprising, as kids are getting wired earlier now than ever before. But this hasn’t always been the case. In fact, there are lots of people out there that have had very limited exposure to computers or are not confident enough to use them for work-related tasks. This could be holding them back in their careers, which is why computer training courses might be a good idea.

Computer training courses can help you gain the valuable skills you need in order to succeed in today’s workplace. Computers are a fact of life and are critical to most business operations, so if you don’t get up to speed soon, your employer just might deem your particular skill set obsolete. Fortunately, it’s very easy to locate good computer training courses in your area or online, which means you can start learning as soon as possible.

There are lots of different types of computer training courses, ranging from teaching students the most basic functions of a PC, to intermediate and advanced activities. If you’ve never used computers before, then you should definitely start with the basics. But if you already know what you’re looking at when you sit down in front of a monitor, then you might want to take computer training courses that focus on word processing, spreadsheets, HTML, or other common applications and programs. Advanced users might be interested in graphic design classes, video game programming, or other high-end tasks.

Some of these classes are offered online, which allows you to study from the comfort of your own home. The course would probably make heavy use of video tutorials, diagrams, and PowerPoint presentations to take you through the content. True beginners should probably look for computer training courses they can attend in person, as this group is likely to have more questions or more difficulty executing assignments — at least in the early going. The final choice is up to you, of course, so go with whichever approach you’d be most comfortable with.

For those of you looking to save a few bucks, an excellent starting point would be a public library. Community libraries often offer free computer training courses to patrons looking to turn themselves into more marketable employees. Seniors, retirees, and hobbyists are also prime candidates for a class like this.

The bottom line is that there’s simply no excuse to be afraid of computers anymore. They’re a fixture of modern life that won’t go away anytime soon, so it’s time to bite the bullet and enroll in a few computer training courses now!

Computer hardware security

Physical information security deals with physically protecting data. Generally, many companies and organizations as well as individuals place great importance in protecting data by use of a software or via a network. Unfortunately, physical attacks to acquire data are common and are sometimes classified as social engineering attacks. The need to protect information cannot be overemphasized, financial, competition, privacy reasons are among the many reasons behind it. Computer hackers, corporate spies and other malicious individuals will however spare no expense if the information is going to benefit them in some way.

Well, enough of talking about the need for protection. Letís talk about solutions to these problems. What can you do in computer hardware security to ensure that your data and information is well protected? One is to purchase and install a firewall security appliance. Physical firewalls offer protection from spam mail, spyware and central policy management that makes the entire process easy.  A hardware firewall is positioned between the computer and the modem. Some routers also have an inbuilt firewall and can be used to offer protection to multiple computers on a network.  Hardware based firewalls have the advantage of having their own operating system running independent of the computer operating system, thus offering an additional line of defense should the computerís operating system and security settings be compromised.

Computer hardware security by use of devices called dongles is also considered more secure than implementing a purely software-based security option. For dongles to be compromised, physical access is required, thus they offer one of the best protections. Another advantage of using hardware devices like dongles is the fact that read and write access to data is usually very difficult if not impossible. Unauthorized access and tampering is very strictly prohibited thus offering a high level of protection.

Computer hardware security also has the advantage of sometimes requiring a user to log in, log out and set other privilege levels only on a manual level. Sometimes, this access is only permitted by use of biometric technology. Sometimes this access is permitted based on the current state of the userís hard disk and DVD controller.  This high level of protection in computer hardware security offers protection that software cannot override.

Computer hardware security can offer high level protection when well implemented and when combined with a software component. However, no system is full proof. You can be sure however that with computer hardware security, your data just got a little more safety.

Making Phone Calls over Internet Connections.

With the advent of VOIP (Voice Over Internet Providers), you can now make phone calls over internet connections that sound just as good as if you were using your regular house phone and often even better. Due to the proliferation of fiber optic cables, satellite service and digital broadband access to high-speed internet service around the world, it is now possible to make quality phone calls over internet services such as Skype, Vonage, or several others that are just now entering the marketplace.

Using Skype is simple and you need to first download the software from their web page at Once you have downloaded the software on your computer you just need to purchase a USB headset. You can get one of these pretty cheap at Radio Shack or Best Buy. One of the most reliable brands is Plantronics, but just about any of the $20 to $40 models serve just as well. Most have two foam padded speakers for listening that cover the ears and a band that goes over your head, along with a microphone that sticks out and is adjustable for talking into.

Make sure that the wire that connects to your USB input on your computer has a mute switch on it. Once you have these items you are ready to make calls.

Calls from one Skype user to another Skype user are free of charge, no matter where the two users are in the world. You can be calling from Costa Rica to Sweden and as long as both users are using their Skype software, then the call is free and they can talk as long as they want with no charges. If you are using Skype to call a phone number that is not a Skype number, for example if you are using Skype to call a friend’s cell phone in another country, that is alright also, but will cost you a bit. In order to do this you will need to go to the Skype website and purchase what are called Skype Out Credits. You can buy these in increments of $10 or $25 and then you can call anyone in the world. Rates to each country are shown when you attempt to place a call. Calls to a Nicaragua cell phone, for instance, cost 22 cents per minute and less for a house phone. This is a really low rate compared to buying a prepaid calling card, which normally run for $5 and give you only 20 minutes of talking time and are very unreliable as far as getting connected.

Call quality on Skype is usually excellent and really makes it easy to make phone calls over internet connections that are high speed. Skype does not really work on low speed connections such as dial-up. You really need to have some bandwidth and high speed cable, DSL, or satellite service in order to have a reasonable sounding call. After every call you make, Skype will ask you to rate the service by filling out a small survey which appears as an annoying pop-up window.

Skype and Vonage both work the same basic way and you can easily make phone calls over internet services with both of these great systems.

Refurbished Computer Systems

Refurbished Computer Systems are All I Buy.
It used to be that whenever it came time to buy a new computer, I would go to an electronics store, spend over a thousand dollars, and always wonder if I had made the right choice.

A few years ago, my brother introduced me to a web site that sells refurbished computer systems, and I have not bought a new computer since.
First and foremost, I can get refurbished computer systems for a fraction of the cost that a brand-new computer system would cost me. In this day and age, that is a very big thing.

If I am going to make an investment of over a thousand dollars on anything, I had better to be able to either live in it or drive in it and be able to pay it out over time.
The second benefit of refurbished computer systems, and for me really the most important point, is that with the refurbished systems you know that everything is going to work properly. The reason they are refurbished is because there was something wrong with them that has been fixed, so now they run properly and will probably do so for years to come.
I have purchased two refurbished computer systems and both have served me very well. I had one for five years and never had a problem with it at all. As a matter of fact, I decided to pass it on to my younger sister. She was starting college, and I wanted to make sure that she had a good computer to do her school work.

The second refurbished system that I purchased was about two years ago, and once again, it works like a charm. I do a heavy workload of assignments as a freelance writer, and the computer holds up nicely under constant use and never gives me any trouble.

I recommended refurbished computer systems to a couple of friends who use their computers most of the day every day, as well, and both were very happy with the results. One of them told me that before  he bought a refurbished system, he would actually have to save up in order to buy a new computer and said it would always break the bank for him. Now, he can easily afford a system and knows that it will work just as good as a new system, if not better.
I don’t think that I will ever buy a new computer again. I know that for some people, a new computer is very appealing, and they would much rather have that than something that has already been used. That is fine. As for me, however, refurbished computer systems are all that I will use from now on, and I feel perfectly confident in doing so.
