Cloud Computing

When considering the future of the information age, many experts agree that the cloud, in this case, is not a bad thing and indeed the future looks bright. Computing, as we currently know it, is predominantly defined by client to server relationship, where for example a number of client terminals, or personal computers, are connected and reliant upon a server for local area network communications and sharing of data but not reliant on that server for individual software and, or application needs. The personal computers in this case are the clients and the server simply serves as the center for interlinking and sharing of multiple resources and data between each client. The server is also generally physically located in the same place as the clients.
Cloud computing is an evolutionary step from the client-server relationship to one where, though servers are still involved as the central node for interconnecting multiple users, the servers are 1) no longer physically located in the same space or building as the clients or users 2) do more than interconnect and facilitates sharing of data and resources but also store the software or applications used by each client or user and 3) are third-party owned and operated, where the clients, or users in this case, pay to access the server on either a utility basis (charge for resources consumed) or a subscription basis (fee for a predetermined amount of time of access).
The users in the case of cloud computing are also an important aspect to note in comparison to the client-server relationship. Users in the case of cloud computing are not limited to personal computers or desktops – users can be any device with connectivity and interface capabilities that allow it to communicate with the server where the desired application or data is stored. These devices include PCs, tablets, mobile phones, PDAs and more.
Computer Support
There can be any number of times when one might require computer support of one form or another. When you consider that more and more people around the world are now either owners of personal computers or have obtained greater ease of access to a personal computer – the reality is that the need for relevant education and support has only increased in direct if not greater proportion, as well.
Computer support is not only limited to the PC hardware, where a monitor, hard-drive or motherboard may be in question. Computer support also includes the operating system and all additional software. You need only browse the internet for available PC applications to get a glimpse at the enormous market for software support. If, for example, your accounting software requires an upgrade and you are told that the upgrade will only function under warranty if the operating system is of a certain version, then you can quickly understand how easily maintaining your computer functioning properly can get beyond the capability of the average, novice computer user.
Now, should the worst happen, and your computer is out of warranty and your hard drive crash – then you are looking at needed support in accessing all the trapped, or otherwise lost data in your hard drive, transferring it to your replacement computer and loading all the necessary and current software onto your replacement computer in order to access the data from your original, or previous computer. The importance and increasing need for adequate computer support is not a component of our growing dependence on computers that should be overlooked.
Computer users are thereby encouraged to carefully research their options when buying or upgrading their computer. This involves a careful study of the costs involved between the various options for computer support should help be required. Each computer user must also asses his ability to personally troubleshoot, should a problem arise.
Hardware Basics
The days when computer usage was limited to scientists and wealthy individuals are long gone. There have been more than one billion personal computers in use around the world since 2008 and it is believed that the number will reach two billion by the middle of this decade.
Each day more people are learning how to perform basic computer operations. Some are adults who’ve finally succumbed to the fact that computers are here to stay, and others are the current generation of America’s youth. Many grade school students know how to type up homework assignments in Microsoft Word, research a word’s spelling in online dictionaries, and send emails to their grandparents who spend six months each year living in a retirement community in Florida.
While many people are learning these simple computer functions, many of these same people are unaware of or don’t acknowledge what the basic parts of a computer are.
The first important point to make is that the physical parts of a computer – the components that you can actually feel and see – are grouped together in one category and referred to as hardware. In general, a computer, namely a desktop setup, has the following hardware components:
- A screen/monitor, the part of the computer where the user can see what he or she is typing or reading. It is the output visual display.
- A speaker system, the part of the computer that outputs sound to the user. The speakers can be built within the monitor or can be a separate attachment.
- A mouse, which has two buttons and is a means for the user to navigate around and interact with the computer.
- A keyboard, which is only utilized when the user needs to input text into the computer. Using a keyboard, like a mouse, is second-nature for most computer users.
- A system unit, which consists of a floppy disk drive, a CD drive, and a hard disk drive that is stored inside the actual unit. Of the basic hardware components, this is the one most users know the least about.
Power Management
Knowing for when and how long to program your computer and other accessories in power management is an important consideration for regular computer users. Too often people leave their computers running, usually with the monitors turned on, and have a screen saver on their screens for several hours, if not days, without powering their systems off.
However powering the average flat screen monitor off will save 25 watts of power per hour. Multiply this by the number of hours your monitor lies awake, even in screen saver mode, and it adds up. As a matter of fact, the U.S. Department of Energy has noted that approximately 75% of the electricity used to operate home electronics is actually consumed when these devices are "turned off." This means that more than half, three quarters of the energy consumed by home electronics is wasted.
It is not a small percentage of electricity that is consumed as a result of not powering off our electronic devices. It is actually a majority of the energy used that is wasted. So what can the average person do in order to be less wasteful and more conscientious about energy consumption when it comes to home gadgets? For starters, instead of walking away from your computer, put it on suspend or stand-by mode. This will lower energy consumption on a laptop computer from 60 watts when being used to 25 w when it is idle, down to 1.6 w when in standby mode! A simple click of the mouse will conserve nearly 20 times the energy used versus doing nothing at all.
Another way to conserve on energy is to have all of your electronic devices connected to a power-strip, and at the end of the day simply flip the switch on the power strip, versus turning each device off. There are also programmable power-strips available that will turn themselves off.
Laptops
It doesn’t seem that long ago that laptops were first introduced. The portable equivalent of a desktop computer, laptops revolutionized computing on the go. Business people requiring to take their work with them could now do so, working remotely, without having to carry files of portable storage media. Simply unplugging and packing their laptop computers, work could be done on the same system from anywhere in the world.
Of course, this would always run the risk of damage to your computer, so adequate back-ups of critical information would often be required in order to prevent data loss that could easily jeopardize your primary computer terminal. Nonetheless, portable computing is here to stay and has only evolved into a number of other electronic gadgets with equal processing capabilities of the laptops of yester-year.
Laptops have become lighter, more powerful and efficient. Batteries have also become smaller and more capable of keeping their charge for longer periods of time. It is now common for people to own both a desktop and laptop computers of equal processing and RAM memory capabilities. Most laptops now ship with built-in web cameras for capturing video feeds and video conferencing over the internet.
The next step in mobile computing has become most evident within the smartphone sector, where mobile phones are now sold with applications capable of managing multiple email accounts, texting, surfing the internet, and running thousands of applications capable of performing many of the functions that we commonly rely our computers to handle. Another portable computing device growing in popularity is the tablet PC or pad computer. These seem to be growing in popularity among users interested in a less bulky device with the similar display size of a comparable laptop computer. In many cases, there is no keyboard attached and are thereby equipped with a touchscreen to operate.
The Internet: Accessing It with the Right Hardware
Getting on the Internet is one of the most enjoyable things to do on a computer. Whether you’re checking your email, reading the news, or having fun playing a game or chatting on a social media site, there’s always something to do. There are a lot of different ways to get on the Internet, as well, and which one you use will depend on several things. Price matters, as do the options you have based on where you live. Another thing that will affect how you get on the Internet is hardware. If you have a regular, dial-up modem, you’ll need to access the Internet by dialing a particular phone number. These kinds of connections used to be very common, but they aren’t very popular anymore. They’re slow, they tie up your phone line, and they frequently disconnect, making using the Internet very frustrating.
Modems are also available for DSL and cable. These are a lot faster, and they are ‘always on’ connections – meaning you don’t have to dial into them. You just open your browser, and the Internet is waiting for you. These kinds of connections cost more than dial-up, but most people think that they are well worth it because they’re so much easier to deal with. Being very fast, they let you browse the Internet and read the things that interest you. They also don’t just disconnect like dial-up connections, so they’re more secure and less aggravating.
You can also get Internet by satellite. Depending on whether you do this through a company that puts a dish on your roof or whether you have satellite TV and use that dish, the price can really vary. The company you use can affect the price, too, so shopping around is important. With any Internet access, ask questions and compare prices. One type of access may be cheaper, but will it do what you want? What about comparing two different companies that offer the same type of Internet service? That can also greatly affect how much you pay and the quality of the service that you get.
Desktop or Laptop: Which Computer Hardware is Right for Your Business?
Many people think of businesses as needing these huge banks of computers, but that’s simply not the case anymore. Instead of needing that much space, businesses can now do a lot of their work through cloud computing. When they do that they need a lot less hardware, which saves them money. For your business, the biggest computer hardware decision will likely be whether you want a desktop computer or a laptop. The nature of your business will often dictate that. If you (or your employees) are stationary and in cubicles or at desks all day, a desktop model will work well. While it takes up more space than a laptop, it can also be upgraded as need be so it can hold more information and so it can be faster. Laptops generally don’t have those kinds of upgrade options quite as easily – and sometimes not at all, because of their limited size.
For employees in the field or business owners who travel a lot, a laptop computer may be a much better choice. A desktop computer isn’t designed to be moved around, but a laptop can just be picked up and carried off. It can go with an executive on a business trip, an insurance agent who’s arriving to handle a claim, or a writer who just wants to sit outside in the sunshine while he works on that latest article. Laptops are very versatile, which is why so many people like them. They provide convenience, and they can do most of what a desktop computer can do.
If you’re unsure about which one to get, think carefully about what you’ll be asking the computer to do, whether you’ll need to move it, and what kinds of expansion capabilities you need it to have. By looking at the largest factors that will affect your choice, you should be able to tell which computer hardware will be right for your needs. Consulting with the professionals never hurts, either, especially if you aren’t certain what kind of price range you should be looking in or exactly what features you need.
Computer Hardware has Come Down in Price
When personal computers first came out they were slow, cumbersome, and largely unaffordable. Now, they’re small, fast, and almost everyone can afford to own one. That’s a great thing for people who run home businesses and for people who just want to check their email and see what’s happening online. If you have a computer that you rely on and it breaks down, you can quickly get frustrated and feel lost. You want to get it fixed as soon as possible. Whether you do it yourself or take it to a professional will depend on several things. First, do you know what the problem is? If you do, that’s the first step toward deciding whether you can fix it. If something just needs replaced and you feel comfortable taking your computer apart, you can save yourself some money.
If you’re not sure where the problem lies or you don’t feel safe taking the case off of your computer, take it to a professional and have him fix it. Yes, it will cost you more than it would if you did it yourself, but it’ll be worth it for the peace of mind that you’ll have. No matter which way you go with getting your computer fixed, there’s some good news. Computer hardware is less expensive now than it was in the past. That means you’ll pay less, no matter which option you choose. In a tight economy, that’s good to know.
Also keep in mind that you can shop around for computer hardware, just like you can shop around for anything else. You don’t have to buy it from the first place you find it. Check around and see what kind of a deal you can get on the specific piece of hardware you need. Proceed with caution, though, because the hardware you’re buying has to be the right kind for your computer. Knowing your computer’s specifications can help you be sure that you’re getting something that will actually work for your purposes. Don’t rush to buy something you aren’t sure about. Getting the right computer hardware is important.
Buying the Right Computer Hardware for You
Everyone always talks about the new software they got for their computers, but what about hardware? It seems like it gets neglected in conversation, but it’s really very important. The processor speed, the memory, the size of the hard drive, and other factors all matter a great deal. What you’re trying to accomplish with your computer will affect what you need in the way of hardware. Desktop computers, for example, often do more than laptops. They have more computing power in many cases, and they simply have more room for hardware to be added to them. When you have a laptop, what you buy it with is pretty much what you get. There isn’t room to add anything inside. If you want a larger hard drive, it’ll need to be external.
For some people, that’s just fine. Others don’t like that idea, and they want to have everything in one neat package. You’ll have to consider what matters the most to you when you’re buying a computer. If you do decide to add or change hardware later on, it’s a good idea to have an experienced person do it if it involves opening the computer’s case. It can be risky to take the cover off of a computer, because there’s so much that could go wrong on the inside. There are areas you just shouldn’t touch, and ways you can damage the computer even if you’re being very careful.
If you do decide to upgrade or replace internal hardware yourself, make sure you find out how to do it properly and follow the instructions carefully. Go slow. It’s not a race, and you won’t win a prize for completing it in the fastest time. Ultimately, what matters is that the computer works properly when you’re done. That’s much more important than whether it takes you fifteen minutes or three hours. If you run into a problem, consult a professional so you don’t make the problem worse. When you plan and pay attention, handling computer hardware is much less difficult.
The Benefits of HDMI

- Image via Wikipedia
Just as several advances have taken place in the realms of processor speeds, memory, display resolution and clarity, so have similar improvements bee made in how the various components of a computer connect to each other. From serial cables that were originally used to connect monitors and and printers to the CPU, now there exist USB connections and infared connectivity. USB in particular is what most PC manufacturers have long hoped will become the standard for all component connectivity, thereby minimizing the number and variety of inputs required on the typical body or chassis of a computer. With only a single, or at most two primary input technologies used by component and accessory manufacturers, then PC makers need only build their machines to satisfy these modalities while conserving precious space and money during their PC build-outs.
One particular interface that has grown in popularity since late 2003 is HDMI (High-Definition Multimedia Interface). This technology has coupled high definition audio and video connectivity from PC to Monitor in one cable. No longer do computer users require two separate cables, one for their monitor and one for their speakers. This not only conserves valuable space on the computer chassis, but also takes away the need for separate video and sound card slots inside the computer, without sacrificing high-definition capability of both. A single HDMI cable supports standard, enhanced and HD video as well as 8 channels of compressed or uncompressed digital audio.
Finally, HDMI is by no means limited to only PC applications. As a matter of fact, this interface is designed to transmit HD audio and video data from most audio/video sources such as video game consoles, DVD players, PCs and AV receivers to digital audio devices such as digital televisions and computer monitors. HDMI provides a solution that has obtained industry wide acceptance for digital connectivity between your computer and your television.
