Techniques Clean A Hard Drive

One appropriate time to clean a hard drive is after a failure has occurred. If the hard drive on your computer has failed and been replaced with a new one, it may still be a good idea to clean the failed hard drive. It may seem unnecessary to remove data from a failed hard drive, but the fact is that there are many people who will be able to recover data from the drive, and if you simply put it out with the garbage there is no telling where it may end up.

Many communities have recycling programs in place for computer equipment, and if your neighborhood has such a program you may want to dispose of the failed hard drive that way. If no such program exists, you can try magnetizing the hard drive by passing a powerful magnet over it, using a special wiping software to overwrite the data with useless information or even destroying the hard drive with a hammer.

It is also important to clean a hard drive thoroughly if it is to be sold or given away. When you consider that many of us use our personal computers for such sensitive things as banking, shopping and investing, it is easy to see how a computer in the wrong hands could easily put you and your identity at risk. Even if you have total trust in the new owner of the computer, you have no way of knowing where that PC and the information it contains will eventually end up.

That is why it is so important to clean the hard drive carefully and completely. It is not enough to simply delete the files and empty the recycle bin, as the files are still out there on the computer and will be quite easy to recover for those with the skills to do so. It is important to clean the hard drive by using a quality wiping program. There are many such programs on the market, including software products by Symantec, McAfee, Computer Associates and other large manufacturers, as well as some excellent programs written by independent programmers. These cleaning programs not only erase the data; they also overwrite it with useless information, making it virtually impossible for those with malicious intent to gain access to your personal information.

Some Advice About Desktops

Be on the lookout for computers that the owners are giving away. Many people decide to purchase a laptop and will sell their desktop at a very reasonable price. It’s still prudent to verify the functionality before you make an offer, though such a computer is going to be in fine shape. Look at all add-ons you are purchasing with the computer. There are many accessories that you can purchase for your new computer. Really, only purchase the ones you most need. Also, make sure the add-ons aren’t available elsewhere for much less. Those from the manufacturer are sold at higher prices.

When creating a desktop computer at home pay attention to the types of products you use. Some motherboards will only be compatible with particular processors. Certain RAM units only work well with particular motherboards. When buying the individual computer components it is important they are compatible with each other. That is going to save you money and time when you are working on your own computer. In order to keep your desktop computer running at its maximum efficiency, and to ensure the fan is cooling the components dust the interior once a week. Usually it is pretty easy to take the case off and then just spray the dust away with compressed air. That will clean the computer and help the fan to work.

Check tech sites online for computer reviews prior to purchasing. You can easily get overwhelmed with your options when looking for a computer. If you look for quality reviews written by technical professionals, you will be able to get the one that will perform as you expect it to. Be certain you can get a warranty when you buy a new desktop computer. If there are any software issues or if anything else would fail making the computer unusable, this is especially important. If necessary, generally, you’ll be able to get repairs done, or replace the entire computer.

Best WiFi Printer

The wireless network connectivity is as per with modern day need. You can connect your mobile by creating a hotspot or within a same network. Just simple set up procedure – You have to download the Brother app from App Store and connect the printer and mobile in a same network. A router or mobile hotspot will do the trick to connect the printer.

Except from the wifi its performance and agility is far beyond its HP counterpart MFP 1005. The printing time so less, and the jamming is very rare, except for the sticky pages.

Also, the cartridge longevity is far much better than any laser printer currently available in the market. It can easily go on to print about 1500 or more pages approximately. You can easily refill the cartridge at your will. Though you have to be little bit arduous for that. Better call cartridge re – filler.

It can easily print 80,85GSM quality paper with both side printing. It has a face down paper output with face down paper input.The memory capacity of the laser printer is 32MB – which is good enough to hold the linking MAC address and printer spooling at high speed.

Print speed is 21ppm for Letter Size paper and 20ppm for A4 size printing which is good enough to be flawless. Brother laser printer is better than its counterpart in this regard. Resolution is Up to 2400 × 600 dpi which is good enough.

Examining Computer Hardware

Checking the Keyboard
The keyboard might not seem important as a hardware component, but it is used in almost all tasks and taken for granted. For laptop users, the keyboard is very important. If one has to send the laptop away for repair the entire computer must go with it. There is also an online test tool available to test all your keyboard keys called “KeyboardTester”.

Checking the Disk Drive (HDD & SSD)
Your HDD/SSD has your operating system and most of your applications and files. Having your HDD/SDD completely healthy is very important. This is most imperative when dealing with a used computer since you have no awareness of the previous history or care of the used computer and its HDD/SDD.

Different tools are available to check the condition and health of the HDD/SDD.

HDSentinel is one you can use for your HDD. The left hand side of the screen will display drives connected the computer. Health is the main parameter to look for. HD Sentinel will explain the meaning of the health percentages and the steps that you should take based on the results. As an example, you shouldn’t throw out your HDD just because of a few bad disk sectors and IO errors.

SSDlife is another tool specifically for an SSD. It also shows health in percentages and the expected life of the drive. Similar to hard disks, bad sectors can occur in SSDs.

Checking the Processing Units (CPU & GPU)

The main components that do all the processing are the Central Processing Unit (CPU) and the Graphics Processing Unit (GPU). These are the components that allow you to run your office applications and your games. These are also essential components to ensure are in perfect working order. So it is necessary that these two components should be in perfect condition. For testing both, we use CPU speed test

For testing your GPU, the tool.Base Mark Web 3.0 works just fine.

Removable USB Mass Storage

The development and adoption of removable USB mass storage is truly remarkable. Never before has it been so easy to move gigabytes of information around on a portable device that is small enough to clip onto a key chain. These pocket size devices are known as a jump drive, thumb drive, flash drive, USB drive or USB flash drive. These devices have large capacities and they can copy data at lightning speed. It’s hard to buy a USB flash drive these days with less than 128MB of storage and some devices can achieve data rates greater than 20MB per second. The technology is so convenient and powerful that we wonder how we could have lived without it. It’s unthinkable to use floppy disks for the amount of data that we need to carry around today. While the capacity of a CD-RW might be sufficient the procedure of inserting and “burning” simply can’t compete with the ease of plugging a flash drive into the USB port.

To deal with this issue, some organizations have disabled USB ports through the BIOS, while others have gone to the more extreme measure of filling the USB connectors with a thick epoxy adhesive. While this solves the problem it also prevents any beneficial uses of USB mass storage to be garnered. But what other functions are there for USB mass storage devices? Besides moving large amounts of data around at lightning speed what else could we be missing by banning their use? Surprisingly, there are very compelling advances to be gained in the security industry by properly harnessing the power and protocol of USB mass storage.

USB mass storage devices are evolving and we are starting to see many new features and behaviors that were never conceived when the USB mass storage specification was written. For example, many devices today offer encrypted storage so that if you lose your device, the information on it remains safe. Some flash drives even have fingerprint sensors and processors built in so that biometric authentication of the owner is required before the storage can be accessed. These are examples of some security driven extensions to the basic functionality of mass storage. The on-board capabilities of strong cryptography and authentication that we see on some of the more advanced devices are the prime ingredients for a new direction in the evolution of USB mass storage. That direction is Portable Security Devices that offer identity management and secure storage.

Digital identities take many forms. They can be simple credentials such as usernames and passwords, or more complex forms such as PKI based X509 certificates or claims based assertions in SAML tokens. To be really useful in today’s identity infrastructures an identity device must be more than a secure store of static credentials. It must also be able to generate cryptographic keys, perform digital signature operations, parse request messages and emit security tokens in standard formats. Furthermore, it must bind identity operations to an authenticated user and be able to enforce security policies that have been defined by security officers.

One doesn’t normally associate these operations with USB storage. In fact, digital identity functions are very different from mass storage, but that doesn’t mean that they cannot exist on the same device, just as digital cameras now exist on cell phones. Despite the differences there are significant benefits to putting digital identity functions on a USB mass storage device.

The obvious question that comes to mind is why is it not just a simple matter of creating a composite device? After all, digital identity devices already exist in other form factors such as smart cards and yes, USB key fobs. These could easily be integrated into the same physical package with relative ease to produce a combined mass storage/digital identity device. The answer is that the benefits that we gain go beyond the convenience of having a multi-functional device and are attributable to using the USB mass storage protocol itself.

The USB mass storage interface itself has a number of desirable properties. First it is ubiquitous. Practically every PC and operating system in use today supports it natively and there are no device drivers or software to install in order to use a USB flash drive. This is what makes them so portable and interchangeable. It doesn’t matter which vendor or brand of USB memory stick you have, as long as the device implements the specification it will work.

Portability has been the Achilles’ heel of smart cards and USB tokens. Wouldn’t it be nice to be able to carry a smart card around without lugging a reader, device drivers and proprietary middleware? Without all of that the smart card just won’t work. In fact the situation is worse than that. Even when you have deployed a smart card solution with all of the required components and middleware, you’ll probably find that the solution won’t work with another brand of smart card without swapping in new middleware components.

The U.S. Government has addressed these interoperability challenges by developing GSC-IS (Government Smart Card Interoperability Specification) so that they can deploy smart cards to federal employees without being tied to one smart card or middleware provider. Despite these and other enormous efforts on standards and interoperability, smart cards have suffered from the lack of widespread adoption of a common specification.

The widespread native support and high bandwidth of the USB mass storage interface enables a digital identity device to be truly portable and accept high level application messages through a protocol that is as simple as reading and writing to a file. Work in developing open specifications to exploit this new direction has already begun. In partnerships with key device manufacturers, Microsoft is currently developing a specification called PSTS (Portable Security Token Service), which will enable file system based communication to USB devices that can be used as portable credential carriers and generators of SAML tokens in response to WS-Trust requests.

This is part of a digital identity metasystem that will enhance privacy and security of digital identity transactions on the web. WS-Trust, along with other WS-* specifications are already submitted to OASIS for standardization. With the adoption of InfoCard in new Microsoft operating systems and popular browsers, it will be possible for you to roam to any machine, say at an Internet café, and perform a digital identity transaction using your USB digital identity device.

There are still challenges to be addressed to make this direction a reality. Device manufacturers need to design for portability. The installation of drivers and middleware to assist in some of the digital identity computation is not an option. The device itself must be able to process high level messages, perform cryptographic operations and handle user authentication internally, otherwise portability will be lost. The development and adoption of standards must continue relentlessly otherwise we will fail to achieve interoperability. Finally, the industry must be assured that these new devices are secure. The same types of security validations that are being applied to smart cards and other security modules will be needed.

Now that we have seen the new digital identity direction of USB mass storage devices and what it could mean for portability and interoperability, organizations should rethink their decisions to disable USB mass storage. There are good solutions appearing on the market that can control the use of USB mass storage without disabling them completely. For example, many offerings allow you to prevent any unwanted devices from being used except those that are issued or approved by the corporation, and you can even monitor the files that move on and off a device.

Digital identities play a key role in many security applications from single sign-on, to PKI, to the emerging systems of federated identity. By keeping USB mass storage enabled, corporations can leverage the new breed of USB mass storage based digital identity devices to enhance and simplify their deployments of digital identity security solutions.

Tricks For Printer Shopping

You should definitely shop around when looking for a new printer. Don’t feel obligated to buy the first one you find. Ask a lot of questions so you can do thorough research to ensure this is the printer that will meet all of your needs. Reading reviews of the different types of printers available would be an excellent idea before you begin shopping for a new printer. Asking for the opinions of friends and family about what printers they use would also be a good way to get a recommendation.

Are you going to need special inks for the printer to get the best possible print quality? If this is the case this can become a large expense for you as the consumer. Typically a great print should not need top of the line ink to make a high quality print.

An important issue to consider while shopping for a new printer is: Are there compatible printer ink cartridges and refill kits available to use with the printer you are interested in purchasing? The cost of replacement printer ink cartridges produced by the manufacturer can be many times more than the printer itself so compatible printer inks can be a huge money saver.

Does the ink in the printer smear when touched? A good quality ink should be fast drying and not smear when touched. If it is at all possible you should ask a sales person to print a test page on a printer that you may be interested in purchasing. Also you should ask if you can see a test copy printed on normal paper. The laminated paper used in a lot of shops will make the print quality of any printer appear to better then it actually is.

Another thing consumers should consider when shopping for a new printer is that many refurbished printers cost considerably less than brand new printers and still carry a full manufacturers warranty. This could be a great money saving purchase if you are on a budget.

These are just a few of the things that consumers should keep in mind before purchasing a new printer for use at home. If a good amount of research is done before a purchase is made, most consumers will end up with a great printer that should meet all their printing needs.

Increase Laptop Battery Life

Lower the Resolution
Modern laptops contain high resolution screens which draw a lot of battery power; reducing the resolution to a basic one when you wish to have more battery time is an efficient way to decrease the power consumption.

Turn Off the Keyboard’s Backlight
Unless you don’t have a laptop with a keyboard that features a backlight, switching off the backlight helps to further increase the time before the battery runs out.

Close Any Unnecessary Apps and Processes
Hardware is not the only component consuming your battery, it is the software too. So start by closing any programs running in the background; for example, processes related to sound, music players, video players, or cloud services can be safely closed.

Don’t Let Your Laptop Overheat
Do you use your laptop on your bed, blanket, or pillow? If so, chances are you risk damaging the battery and the internal components; excessive heat will not only cause damage, but will shorten the battery life as well. Therefore, place your laptop on a hard surface like a desk or a table and if you are feeling lazy, use a portable table like a lapdesk.

Computer Networks

A computer network can be understood as a number of computers connected together to share resources. The most common resource shared is the internet. Other resources can be printers, file servers, etc. The computers in the network may be connected through an Ethernet cable or wirelessly through radio waves.
Now we will see how the individual computers in a network are connected:
Computers connected in a network are referred to as nodes.

Star Topology:

In this case, there is a central node from which connections are provided to individual computers. In this case, even if there is any problem with a particular cable, the other computers can continue to function undisturbed. On the flipside, this type of connection requires a lot of cabling.

Bus Topology:

In this case, all the computers are connected by a single cable. The information that is intended for the last computer needs to travel through all the nodes. The chief benefit is that it requires minimal cabling. However, if there is any fault in the cable, all the computers are affected.

Ring Topology:

In this topology, all the computers are connected through a single cable. The end nodes are also connected to each other. The signal circulates through the network to reach the intended recipient. In case, a network node is configured incorrectly or there is some other issue, the signal will make numerous attempts to find the intended recipient.

Collapsed Ring Topology:

In this case, the central node is a network device known as the hub, router or switch. This device runs in a ring featuring plugins for cables. And, each computer is independently connected to the device through individual cables.

Each organization chooses its own topology of the computer network to ensure a streamlined functioning of their computers. Once the computers are connected, offices also have separate cabling closets, which is essentially a space containing a switch device that connects to the network.

Technology of Tapes

Legacy formats such as Digital Linear Tape (DLT) were a reasonable data storage AITernative in the past, but a combination of new business challenges and new technology choices are driving many companies to rethink their tape storage path. For example, conventional DLT systems are approaching the end of their useful life cycle, with no well-defined way to add capacity without upgrading to a new format. While Super DLT (SOLT) and Linear Tape Open (LTO) systems do have roadmaps to the future, neither format offers a compatible solution that can span the gamut of storage needs, from the entry or workstation level up to the “Super Drive” level. In addition, upgrades require a media change, making long-term use of linear solutions more cumbersome and less flexible.

Perhaps, as Frost suggests, it’s time to consider a different path. Advanced Intelligent Tape[TM] (AIT) data storage solutions from Sony provide a broader range of capacities, increased performance, better reliability, easier maintenance and a more strategic path to the future than the AITernatives. Organizations choosing the AIT path will find themselves with a more flexible and integrated tape storage format that can span backup needs from individual PCs, to workgroups, to the enterprise.

AIT is a proven storage technology with years of successful enterprise deployments behind it. First appearing in 1996, AIT is a compact, helical scan 8MM tape format in a 3.5-in., half-height form factor. With its high capacity (up to 100GB per cassette), speed and reliability, AIT is emerging as a more strategic tape storage path compared with linear formats such as DLT, S-DLT and LTO. Consider the following advantages of AIT:

* Reliability — Consistent operation and assured reliability are two critical components for a tape storage system. AIT-3 drives are designed for a mean time between failure (MTBF) of up to 400,000 hours (compared with DLT’s 250,000 MTBF rating) and a 100{4646bdd1b222b0f5160c93ca4a35d1c2744f07729a140324e8de7c4588981806} duty cycle.
