Data loss is inevitable, but it s preventable: the non presence of paper records in lot of businesses indicates that a secure and an offsite data backup should be maintained. Data is irreplaceable and not intangible without a clear backup copy. Data is probably the single most valuable asset of anybody s business. Most of the businesses have insurance and warranties of many items in the office, but the chance are that data is not protected or protected properly.

Computer crashes, thieves steal, buildings burn and backup tapes frequent failure can leave your security of data to chance and your business may even have legal liabilities.

Manual backup to cd, tape, floppy or USB is dangerous if you are using a floppy, cd, DVD, USB drive or tape to backup your data for business then sadly these devices frequently fail. The business owners have the hard way all over the country that if process isn t automated it really doesn t get done. Added to it the security issue of the storage tapes, cd s, floppy disks or USB drives. So the company information can easily be compromised and accessed so the storage and transfer must be controlled and secured. All these variables make this option a poor solution. Business transactions now are done electronically and the data is stored digitally data is the most valuable asset of the company. But the statistics show that small and medium businesses are not protected against that data loss. Research shows that the 30% of the small business agree that they have no formal data backup and good storage procedures. Imation small business backup survey says that more than 40% of businesses rate automated data backup and recovery as the companies IT need. Access markets international.

A single incident of the company s data loss costs a business s an average of $10,000. Gartner research reports that 43 % of the companies which suffers from large scale data loss from disasters never really re open and 29% of companies close within 2 years. Contingency planning research and strategic research corporation says 93% of all companies experiencing data loss are totally out of business just within five years. So there is need to perform online server backup
Will your current backup system fail you?

May be the companies have data backup solution in place but the question to be asked is how smooth the recovery process is when the companies have data emergency? How long will it take the company to get the data back ?

With every upgrade of the computer processor, the techno-savvies experience faster processing and better performance. After the dual core computer, the quad core computer is a revolution in the arena of PC processors. Considered as a part of multi-core processor family, the quad core computers have displayed a significant increase in computer performance and there is no doubt that it is much faster than its previous generation processor. The faster performance of the new age processor is due to the algorithms used in the programs and it depends on the type of programs that run.

Wonderful performance:

When parallel programming and multi-tasking ability is concerned, performance of quad core computer is simply excellent. Ranging from high-end video game playing provision, Hardware virtualization, audio transcoding, and data folding, to video and photo editing, voice recognition facility, 3D rendering, and data folding, you can get faster performance in quad-core computers. With the multi threading processing it is possible to run maximum amount of virtual machines, the number depends on the memory space available on the computer though. You can work with virtual studio on XP or XP virtual machine. The specialty of quad-core computer is its multi-tasking performance.

The misconception:

Many people believe that the speed of the quad core computer is four times than that of the single processor computer. The concept is not totally wrong, because the processor can speed up the processing of only those programs that are specifically designed to run on quad-core computer. In those programs, the codes are written in way that allows to processor to perform four different tasks simultaneously. The multi-threading processor of quad-core computer

Comparing two models of Quad core family:

Intel and AMD are two popular brands of quad core computers. Kentsfield is the first of its kind by intel and also known as core 2 extreme quad-core QX6700. Conroe or Core 2 extreme X6800 is its advanced and faster version. The latest `Core` micro architecture technology is the base of these computers. Apart from being low-powered, the latest generations of these computers give high performance. Their excellence in performance can be observed in the fields such as digital content creation, actuarial sciences, engineering analysis, like CAD and financial applications. Ideally, these computers are best for users who require highly accurate scientific calculation. The mainstream and commercial version of quad-core computers from intel is Core 2 Quad Q6600.

The quad core computers from the AMD are based on an innovative technology i.e Silicon-on-Insulator process. Basically, the computers are built on a 65 mn process. The faster transistor is a unique feature of the computer that reduces the wasted heat and power. The computers from AMD has `Enhanced Power Now` feature which adds to the power saving ability of the device. It allows to run each core of the computer at different speeds or turn off any of the core for more energy saving. The enhanced `Crossbar Switch` another useful feature of the computer that allows the user to access different parts of the cores simultaneously. For much faster `Hyper Transport` speeds AMD has developed its quad core computer with integrated memory controller and the latest `Direct Connect Architecture 2.0`.

Quad core computers are basically designed for high end users and not for the general purpose use. Parallel programming, complex algorithm programs, and multithreading can be easily done with this high-end processor. The demand for quad-core computer will significantly increase in near future as the complex coding programming is increasing in every field.

Used desktops and laptops are actually contributing to the increase in electronic hazardous wastes in dumpsites all over the world. Figures from the Natural Resource Defense Council show that about 130,000 computers are being dumped in the US every single day. Also, hazardous elements from electronics such as chromium, cadmium, mercury, lead and polyvinyl chlorides can contaminate water systems or cause other environmental problems when improperly disposed in dumpsites. If you are concerned about the environment and would want to protect the future generations from the ill-effects of computer waste, then you should know how to dispose your electronic products properly. Here are some of the things you can do.

The first thing that you can do is to get in touch with the manufacturer of your computer. Leading computer makers in the US, namely Gateway, Sony, IBM, HP and Dell can arrange for the recycling of your used desktops and laptops. However, they usually charge fees for their services so you might want to reconsider if you really do not have much money to pay them. It is important to note that not all manufacturers have a recycling program so you may have to look for another way to dispose your used PC safely.

Simply throwing your electronic components and devices along with your regular garbage is morally wrong. As mentioned earlier, electronics contain compounds that can cause severe illnesses, including cancer. So, another alternative is for you to look for recycling companies in your locality or community. There could be a recycling center accepting used desktops and laptops in an area near you. However, some recycling companies will simply send e-wastes from the US to China and other countries in Africa. So, it may be a good idea to check out what the recycling group near you is doing with the e-wastes they collect.

Another way to safely dispose of your electronic wastes, which includes cellular phones and used desktops, is by getting in contact with non-profit organizations whose main objective is to dispose e-wastes in an environment friendly manner. Some organizations earn money for their cause by selling parts that can be put to use by other people. Reconditioning used PC is a great way to minimize the electronic wastes in the US and all parts of the globe. Since refurbished desktop computers and notebooks are inexpensive, you can also help in making computers available to low-income families.

Refurbished desktop computers are giving consumers a cheaper alternative to brand new desktops and laptops. In a time when everyone is scrambling for ways to save money and bring down expenses, it is really wise to consider purchasing refurbished computers. However, it is also not surprising that many people are afraid of reconditioned or used computers because they think that these units would easily bog down. So, here are some steps that you might want to follow to ensure quality used computers.

The first step is to determine where you will use the computer. The components that you will need and the amount of RAM or type of processor that you will require depend on your reason for buying a computer. You cannot expect that all the refurbished desktop computers that you buy will have all the components and specifications that you need. If you are going to use it for gaming, make sure that you have a compatible video card and a RAM that will enable you to run PC games. If you are planning to use it to check your email or surf the Internet, then a modem or a NIC, Network Interface Controller, is necessary. Therefore, the second step in buying refurbished computers is to know the hard drive capacity, RAM, and the specifications of the unit that you are eyeing on. It is also important to check the system requirement of the software which you will use.

The third step is to test the PC before you buy. Do not be afraid to test as many refurbished desktop computers as necessary. You want to make sure that you are not buying a lemon computer and the only way to do that is to see if the hardware components, as well as software, are working perfectly. Also, be sure to ask the seller of the refurbished computers for warranty and return policies. A warranty of six months and above is a fairly good deal when it comes to reconditioned desktop computers or laptops.

Even if you are purchasing refurbished desktop computers, it does not mean that you will need to buy new ones every time you want a software upgrade or you have found new uses for a computer. Thus, the last step is to determine if your cheap computer is open for further upgrades. It is also important to know what if the software you are going to buy or use is compatible with your short-listed refurbished computers.

Surely you have heard of a router before, as it is one of the most popular and necessary computer components. There are also wireless routers which hold many advantages over their wired counterparts. Wireless routers add a built-in access point function to a multi-port Ethernet router, which combines multiple Ethernet networks with wireless connections as well.

Hacking Wireless Routers

When it comes to hacking wireless routers, know that this is not always the easiest task. There are a few things that you will need to be aware of before you will be hacking wireless routers, so listen up.

The only reason that you would be hacking wireless routers is to do something illegal, and so this is obviously the first thing that you need to be aware of. What you should really be doing is learning how to protect your router from hackers, and there are a few steps that you can take to do this.

If you do not have a router then hackers will be able to see your computer on the Internet, and so a computer router is then obviously very important for computer security. By adding a router in your home or office you will be able to create a wall to your computer and the Internet, so this is a necessary step for any computer user.

Besides hacking wireless routers there are also other things that you can do to protect your privacy and security.

Although technically the only surefire way to protect your computer from hackers is to never go on the Internet, because in most peoples cases this is not possible, there are other options. Other than avoiding the Internet, the next big thing you can do is set up a firewall.

A firewall is a secure and trusted machine, one that sits between a private network and a public network and which is used to protect your privacy. The firewall machine is configured with a set of rules that determine which specific network traffic will be allowed to pass and then which will be blocked or refused.

With these quick and easy steps you will be able to set up a great security system for your computer and protect yourself not only from hackers but also from Trojans and other computer viruses and threats.

The most important thing is that you understand just how important an issue hacking wireless routers really is and keep this in mind whenever you are using your computer.

If you want to connect to the Internet and even share a connection among several personal computers connected to a home network you must also find out whether it is possible to connect two wireless routers and if so, how to go about connecting two wireless routers.

Certainly, you will want to add wireless connectivity to your home network if you own a laptop because then you can use your laptop within a certain geographical area without needing to connect the laptop to the modem with wires. Even if you want to connect your PC without wires and then the wireless routers can play an important part.

Simplest Solution

The simplest hardware solution that presents it would be to connect two wireless routers with one router placed with a PC connected to a wired network while the other router is used to connect the personal computer wirelessly. When you do this and connect two wireless routers it is known as an ad hoc wireless network which is well suited for connecting two personal computers.

On the other hand, if you need to connect (wirelessly) more than two PCs and then you will also need an Access Point (AP) that must be wireless or even use a broadband router that is wireless-enabled.

With these items of hardware, you can connect two wireless routers in so many different ways that it would be very difficult to explain all the possible permutations and combinations. Suffice to say that it is possible to use a simple home networking setup that has fully wired as well as wireless capabilities and also use a broadband router that has at least four Ethernet ports as well as integrated wireless connectivity.

A more complicated way of connect two wireless routers is to use a single port broadband router which must be connected to four or even eight port 100 MBps switch that in turn must be connected to a wireless AP.

The minimum cost in terms of money that you will spend in order to connect two wireless routers would be about five hundred dollars which would mean spending in the range of at least one hundred and fifty dollars for a couple of wireless adapters, and another two hundred dollars for a wireless AP plus fifty to hundred dollars for a wireless NIC.

Lastly, when connecting two wireless routers you must also ensure that the configuration is absolutely secure and to prevent unauthorized access you will have to look beyond Wired Equivalency Privacy standard that has thus far proved to be less than successful.

A router is an electronic device that connects a LAN to a WAN and which handles the task of routing messages between the two networks. When a router is used, all Internet traffic passes through it to your LAN or Local Area Network. A router is one of the most important and efficient pieces of computer hardware, and there are even routers available that are also modems firewalls and print servers.

Cable Routers

There are many different types of routers to choose from, cable routers being one of the most popular choices here. If you have high speed cable Internet in your home then most likely you have a cable router. The way that cable routers work is really quite simple.

A cable modem plugs into the cable that comes out from the wall, and then the cable router plus into the modem and transfers the signal to any computers that you have in the home.

There are many benefits offered by these cable routers, one reason being if you have multiple computers. This is because when you have cable routers their signals will not suffer from long range, unless they are wireless. Remember that when you are getting your cable Internet service installed you can ask your installer about which particular cable routers they would recommend.

The Selection

There is quite a selection when it comes to cable routers these days. Keep in mind that when you are out shopping for a cable router you want to consider whether you want a wireless network or to use network cables. This will play a major role in terms of which routers you can choose from. You should also take your budget into consideration here as this too will help to narrow down the selection.

One of the most important steps when choosing a router is to consider the terms of warranty. This is because Internet router manufacturers always provide some sort of warranty package with their equipment, and because the length and terms of these warranties varies so widely.

You should also spend some serious time researching the different models, especially the most popular ones. Word of mouth can also be helpful but make sure that you never rely too much on other people�s opinions because they only go so far. Just because one person liked or disliked a certain cable router this certainly should not be a reason that you are deciding on a particular model.

Refurbished computers are what you need if you are buying a starter computer for yourself or for your kids. Such desktop computers and laptops are quite affordable and truly reliable. Many people who are not really very knowledgeable with computer systems tend to frown upon refurbished desktop computers and other cheap computers because they are afraid that these devices will bog down in less than two years. However, the experiences of countless people who have invested in these PCs are proof that a refurbished computer is dependable. Below are some explanations why these desktop computers can be relied upon.

It is a common misconception to think that refurbished computers are simply old computers that are super slow and outdated. Although it is true that the very cheap computers may be using older versions of software and hardware, models that are in the range of $400 to $700 can already provide you with high powered performance because they are equipped with more recent software and hardware technology. In fact, the majority of refurbished units are from expired leases or corporate upgrades. These means that companies who want to upgrade their office systems to newer computers usually sell their desktop computers to companies that repair and recondition used desktops and sometimes even laptops.

Also, a fraction of cheap computers sold as refurbished or reconditioned are units that have been returned by buyers to manufacturers for slight cosmetic blemishes, such as scratches on the surface or chipped paint. These devices are sold as refurbished after being tested because no customer would buy them as new. There are also some units that have been returned by customers because the seller or manufacturer has delivered the wrong model or color. Since the box has already been opened, they can no longer sell such desktop computers or laptops as new. This means that not all refurbished desktop computers or laptops are used PCs.

Still, a negligible portion of reconditioned computers sold in the market comes from desktop computers or laptops that were returned because they did not work well or they had a few problems. However, you do not have to worry about buying reconditioned cheap computers because all such desktop computers and notebooks are checked thoroughly before being sold. Parts that are not functioning are replaced by components that are working well. In fact, some suppliers even buy new parts to ensure ample performance of the reconditioned PC.
