12 Ways That Renting a Computer Will Save You Money

If you are looking for ways to save money, computer rental is definitely something that you should consider. Not only is it far cheaper to rent a computer than to buy one outright, you can also save yourself money on finance charges, upkeep, maintenance and the headaches involved with owning a brand new laptop or personal computer.

12 Ways Renting a Computer Will Save You Money

There are so many ways to save by computer rental instead of purchasing laptops or a desktop computer that it would be difficult to list them all here. However, the following twelve ways that you save by choosing computer rental should give you an idea of the kinds of savings you are looking at.

Renting a computer is cheaper. Instead of having to come up with hundreds or thousands of dollars out-of-pocket, you can spend a set amount every month.

When you rent a computer you don’t have to worry about the pesky finance charges that so often come attached to computer credit accounts. All the costs are in your monthly rental fee.

Computer Rental is better for the environment. By recycling computers you can cut your carbon footprint on the planet.

By renting a computer you are acting responsibly from a social perspective. Computers are often made by underpaid employees in overseas factories. Reducing the need for this kind of exploitation is acting socially responsible.

Renting a computer instead of buying means you don’t have to spend money on upkeep. Anything that goes wrong with a computer rental, even with the computer hardware is maintained by the rental agency, which will make sure that it gets fixed.

When you rent a computer you don’t have to worry about upgrading your computer. Rental computers are upgraded regularly. If you are renting your computer for the long-term, you are sent upgrades as part of your rental policy.

You don’t have to worry about your computer becoming obsolete. When you are renting a computer the rental agent will make sure that your computer stays viable. If a computer that you are renting becomes obsolete, then

When you rent a computer, you do not have to buy your computer accessories separately. They come with the cost of the rental.

If you get bored with your rental PC you can trade it in for another model such as a gaming pc.

Ready for an upgrade? Say you want something more powerful than your current model, like something that manufacturers have come up with. By turning in your old model and signing a new contract you can get an upgraded computer without having to spend hundreds of dollars out of pocket.

You can choose to rent other equipment as well. If you should, say, want a projector or other piece of equipment, you don’t have to buy those outright either. You can add the cost of renting the projector, even if it is for a short time, to your monthly computer rental bill.

Finally, you don’t have to worry about maintaining a warranty to have your computer fixed. The rental agency keeps the repairmen on staff and keeps you from having that extra charge.

Why Computer Rental is the Smart Choice

PCs can be very expensive. You can save yourself a great deal of money by renting a computer. You can also save yourself a great deal of hassle. By choosing computer rental over purchasing a whole new computer you are not only acting responsibly for your own financial future, you are also acting in the best interest of the environment as well.

Computer Firewall – Why You Need This?

Computer firewall is a piece of software or hardware that helps screen out hackers, viruses, and worms that try to reach your computer over the Internet. If you are a home user or small-business user, using a firewall is the most effective and important first step you can take to help protect your computer. Firewall will not make your computer completely safe. However, a firewall provides the most effective first line of defense. Windows computers can be attacked in many ways – and not just with viruses, worms, or Trojan horses. Another popular way to attack a Windows computer is to attempt to communicate to it over any of the network “ports” found on Windows computers. These ports are kind of like TV channels or radio frequencies: Computers are set up to listen for messages that may arrive from other computers – this is how they communicate with one another.

How computer firewall works

Firewalls monitor all the communication between your computer and the Internet. computer firewall knows what kind of communication are allowed to flow in and out. They know this because they have something called an “access control list” – a list of rules that specify precisely what kinds of communications are allowed and what kinds are blocked. The computer firewalls made for the consumer market are usually preconfigured to offer maximum protection right out of the box. The configuration required to facilitate communication between two computers in a home network makes them highly vulnerable to attack from any computer on the Internet. Whether the firewall is a hardware device connected to your network, or a software program in your computer, a computer firewall will automatically block all unwanted network communication from the Internet, while at the same time permitting any legitimate communication that you need to use your computer.

Type of computer firewall

There are two principal types of computer firewall: hardware and software. A hardware computer firewall is a device connected to the network in such a way that all communications between any computer and the Internet must pass through the firewall and be examined to see whether they should be discarded or allowed to pass through. A software computer firewall is a program that runs on a computer and performs the same type of examination of network communications that a hardware firewall does. But where a hardware firewall can protect all of the computers on a network, a software firewall only protects the computer it is running on.

Things you need to know

Running multiple software firewalls is unnecessary for typical home computers, home networking, and small-business networking scenarios. Using two firewalls on the same connection could cause issues with connectivity to the Internet or other unexpected behavior. One firewall, whether it is the Windows XP Internet Connection Firewall or a different software firewall, can provide substantial protection for your computer. If your computer is not protected when you connect to the Internet, hackers can gain access to personal information on your computer. They can install code on your computer that destroys files or causes malfunctions. They can also use your computer to cause problems on other home and business computers connected to the Internet. A Firewall helps to screen out many kinds of malicious Internet traffic before it reaches your computer. Some firewalls can also help to prevent other people from using your computer to attack other computers without your knowledge. Using a firewall is important no matter how you connect to the Internet – with a dial-up modem, cable modem, or digital subscriber line (DSL or ADSL). So it is wise to turn on the Windows Internet Connection Firewall for all computers in your home network. This helps prevent the spread of viruses or worms across your network if a computer is infected. A computer on the network could become infected through a separate Internet connection, such as one on a laptop that is used on your home network and on public networks. Or a virus could be introduced to a computer on your network by way of e-mail or software installed from a CD or floppy disk. If you have more than one computer in a home or small-office network, you should protect every computer in the network. Turning on Windows Firewall or another firewall on every connection will help prevent the spread of a virus from one computer to another in your network if one of your computers becomes infected. However, if you open an infected e-mail attachment, the firewall won’t block it and it can infect your computer. You should install an antivirus program as well.

Best Gaming Computer: Schools of Thought

With the current advancement in the computer gaming industry, more and more people are contemplating on what are the best specifications to include in their gaming PC. After all, in a world were graphics and speed really matters, who wouldn’t want to own the best gaming PC there is.

Current computer games have placed a great demand on the computer’s hardware. These computer games demand too much as too requiring a fast central processing unit (CPU) in order to function. Initially CPU manufacturers relied on increasing clock rate to improve the performance of their processors. By the year 2005, manufacturers have begun to adapt multi-core CPU technology, which allows the computer to process multiple tasks simultaneously. This allows the computer to use more complex graphics, artificial intelligence, and in-game physics which are core elements in modern computer games.

Many 3D computer games also demand more on a powerful graphics processing unit (GPU) which is responsible for accelerating the process of drawing complex scenes in real time instances. These GPU’s can be integrated on the computer’s motherboard or come packaged with a discrete graphics card. Some modern computer games require physics processing units (PPU), which accelerates physics simulations in modern computer games. These PPUs allows the PC to process more complex interactions among objects which can’t be accommodated by the CPU.

Sound cards are also vital in a pre-dominantly 3D computer games. This hardware provides for improved and enhanced 3D audio of the game.

So what is the Best Gaming Computer then…
The idea of building the Best Gaming Computer is one that has crossed many computer gamers’ mind around the world. But when this idea also comes into play, two schools of thought come into light.

One school of thought is that the Best Gaming Computer is one that has garnered the best and powerful specifications available in the market. PC’s are constructed after a list of computer components found out to be the best gaming machines based on specifications. This is “The Best in the Market” school of thought.

On the other hand, there is also a idea that instead of building the best gaming computer based on the best specifications in the market, one should build the best gaming computer based on the user’s needs. People pursuing this school of thought construct their best gaming computer based on a list of computer components found out to be needed by the user and not what’s the best in the market. This practical school of thought is called “The Best for You” school of thought.

The “Best in the Market” School of Thought
People who are considering that big guns are the best should follow this school of thought. This school of thought believes that the best gaming computer is the one equipped with the best and latest computer component in the market.

The main advantage of this school of thought is that users are assured that they will be enjoying the fastest and best quality (in terms of graphics and speed) experience for their computer games. They can easily play graphically demanding computer games at higher resolutions without a problem.

The main disadvantage of the “Best in the Market” School of Thought is more on the financial aspect. In order to achieve such a gaming computer with the best components in its specifications could shave out thousands, or even tens of thousands, from your budget. If you want the Best then be prepared to pay the price, of course, big guns cost a lot you know.

If you still want to pursue this school of thought and you have the budget to afford such a price then you can visit several websites to check on the best computer components in the market.

The “Best for You” School of Thought
For practical gamers, this school of thought is what suits them best. This school of thought believes that the best gaming computer is one that fits the user’s needs and not the user’s wants.

The main advantage of this school of thought is that it is able to address your gaming computer needs with the less amount of money to shell-out for it. Gaming computers constructed with this in mind may not be the best or fastest there is in the market or in the world, but it is one which is easy on the user’s pocket while delivering the needed specifications to be able to function when playing modern computer games.

If you want to follow this school of thought in constructing the best gaming computer for your needs, here are some hints and questions that you must keep in mind:

1. What will I used my computer for?
2. Will I use my computer solely for gaming?
3. Or will I also use for other purpose: such as listening to music, editing pictures, watching movies, chatting with buddies, or surfing the Internet?

Consider the gaming computer you are going to buy or construct. If you are going to use it for simple tasks; it would be a waste of money to spend on high-end computer components if you really don’t need that much power for these simple tasks.

4. Do I really need that much power?
5. Is 50MHz really worth having?

Ask yourself if you really need those extra MHz or MB that a high-end computer component can provide you. For example, it is great to have a Quad-SLI machine with four nVidia 8800 Ultras powered by a Quad Core Extreme Processor. But do you really need that much power if you just want to play The Sims 2, which can adequate run on a low-cost GeForce graphics card?

For people who are advocating this school of thought, they always believe that “the hardware you are buying today might be outdated tomorrow, so why buy expensive one when it will be outdated after a few months?”

In the end, if you want to follow this school of thought always remember to ask the ultimate question:Is it worth it?

Fifth Generation of Computers

Earlier Generations of Computing

The first generation of computing is generally thought of as the “vacuum tube era.” These computers used large vacuum tubes as their circuits, and large metal drums as their memory. They generated a tremendous amount of heat and, as any computer professional can tell attest, this led to a large number of failures and crashes in the early years of computing. This first generation of computer lasted for sixteen years, between 1940 and 1956, and was characterized by massive computers that could fill an entire room. The most notable of these large, and yet quite basic, computers, were the UNIVAC and ENIAC models.

Second-generation computing was characterized by a switch from vacuum tubes to transistors, and saw a significant decrease in the size of computing devices. Invented in 1947, the transistor came to computers in 1956. Its popularity and utility in computing machines lasted until 1963, when integrated circuits supplanted them. However, transistors remain an important part of modern computing. Even modern-day Intel chips contain tens of millions of transistors – although microscopic in size, and not nearly as power-draining as their much earlier predecessors.

Between 1964 and 1971, computing began to take baby steps toward the modern era. During this third generation of computing, the semiconductor increased the speed and efficiency of computers by leaps and bounds, while simultaneously shrinking them even further in size. These semiconductors used miniaturized transistors which were much smaller than the traditional transistor found in earlier computers, and put them on a silicon chip. This is still the basis for modern processors, though on a much, much smaller scale.

In 1971, computing hit the big time: microprocessing. Microprocessors can be found in every single computing device today, from desktops and laptops to tablets and smartphones. They contain thousands of integrated circuits that are housed on a single chip. Their parts are microscopic, allowing one small processor to handle many simultaneous tasks at the same time with very little loss of processing speed or capacity.

Because of their extremely small size and large processing capacity, microprocessors enabled the home computing industry to flourish. IBM introduced the very first personal computer in 1981; three years later, Apple followed with its wildly successful Apple line of computers that revolutionized the industry and made the microprocessor industry a mainstay in the American economy.

Chip manufacturers like AMD and Intel sprouted up and flourished in Silicon Valley alongside established brands like IBM. Their mutual innovation and competitive spirit led to the most rapid advancement of computer processing speed and power in the history of computing; and enabled a marketplace that is today dominated by handheld devices which are infinitely more powerful than the room-sized computers of just a half-century ago.

Fifth Generation of Computing

Technology never stops evolving and improving, however. While the microprocessor has revolutionized the computing industry, the fifth generation of computer looks to turn the whole industry on its head once again. The fifth generation of computing is called “artificial intelligence,” and it is the goal of computer scientists and developers to eventually create computers than outsmart, outwit, and maybe even outlast their human inventors.

The fifth generation of computer has already beaten humans in a number of games – most notably a 1997 game of chess against the man who was then the game’s world champion. But where it can beat humans in very methodical gameplay, fifth generation computing lacks the ability to understand natural human speech and affectation. Artificial intelligence is not yet as intelligent as it needs to be in order to interact with its human counterparts and – more importantly – truly understand them.

But strides have been made. Many computers and smartphones on the market contain a rudimentary voice recognition feature that can translate human speech into text. However, they still require slow, very punctual dictation – otherwise words become jumbled or erroneous. And they’re still not receptive to human affectation which might indicate the needs for capital letters, question marks, or things such as bold and italicized type.

As microprocessors continue to increase their power by leaps and bounds, it will becoming possible for these hallmarks of artificial intelligence to become easier to develop and implement. It’s easy to underestimate the complexity of human language and patterns of communication, but the simple fact is that translating those things into raw computing power and ability requires a great deal of time and resources – in some cases, resources that have yet to be fully developed and put into a computer chip.
