Pen Drive and its Advanced Features – Not Just a Storage Device?
Embarked with all convenient features of a modern age storage device – atomic size, featherweight, gigantic storage capability and durable strength quality – pen drive is a near to must gismo for all technology freaks. The innovate creation of this evolutionary device – pen drive – has served a Larger than Life multi-functional unit for computer users, being compared to none -a mere storage device that suits all needs.
Average or modest users take pen drive for to be a simple mobile storage device for their data, ad scarcely bother the advanced features and mechanisms this device could other wise be sued for. However, the most tech-friendly and savvy users of pen drive are more careful about its features and understands its creators gift of technology in just these two words.
A pen drive is known for its storage capacity for its basic selection. But technical enthusiastics have built more than just storage capability to this device.
# Storage to size capacity ratio
The omnipresent device has earned its popularity die to its exceptional capability of massive storage in just a capsule sized shell. Pen drives were first equipped wit storage capacities of 512 MB to 1GB, but modern pen drives come up with gigantic storage capabilities from 32 GB to 80 GB, in just a plastic shell that is smaller than the size of your thumb.
Technology experts are yet renovating their formulas to create spaces in Terabytes (hundreds more than 1024 GB of space).
# Compatibility
Pen drive users found a great problem with compatibility options in their device. But recent pen drives are highly encrypted to suit and work best in almost all the operating systems available on the market. Pen drives are tuned nowadays to have the best data transmission between Windows, Mac, and Linux operating system.
# Built-in rechargeable battery
Baby boomers are of the greatest fan and users of this device as pen drive functionality provides a great backbone in their MP3 players. These users need a continues playback options though their earphones while they are out. Thus, this device comes with a rechargeable battery that charge itself when connected to the USB of a computer. MP3 lovers get the best use of pen drive at current world where they can keep their ears and mid busy while they are traveling or at work.
# Display options
Most pen drives of recent age come with LCD display technology that enables its user to browse through the contents of the pen drive direct hand.
# Camera options
Pen drives are also equipped with cameras and all the advanced features that need to be included to make it a modern age camera device. Usually, the camera is a still picture-capturing device, but when connected to a computer, it serves as a web cam.
# What more?
These days, pen drives are also squeezed with tiny speakers that allow you to listen to your songs even after you have lost your headphone.
Some devices also come up with card a reader facility that not only enhances your devices storage capacity, but also adds an extra mobile storage medium in this already mobile storage medium!
Finger spring detectors are also embedded with pen drives to add extra security to its owner.
SO, now you understand pen drive is not just, what you thought it was, it is the whole world out there when you consider this so tiny device built with adequate features and feasibility options to boost your purposes.
Employing A VPN
Virtual Private Networks, VPN, are becoming one of the most important business tools. A VPN service provides remote and mobile business personnel to access to their emails, documents and applications from their computers at a distance. The dependency rate of this VPN service for current age business is such that a VPN system failure can cause a significant risk for the business.
Without a VPN remote access, mobile sales staff place orders or set actions for customer mails. A staff at a distant and remote location cannot process shipments without a VPN service. Thus, a VPN service running in parallel with global the business demands fail, a significant interruption of business wills be seen and it would even result in serious loss in business.
From the number of reasons a VPN service breakdown can occur, two major reasons are to be highlighted,
1. VPN hardware failure
2. Communication links failure
These are the common system failures generally observed in a VPN outage. The time to recover from these system failures depends on how quickly a VPN technology expert can provide a system backup or a system replacement unit or how quickly the communication links are restored.
As a business has the least time to afford to lose or rebuilding or restoring a VPN failure, they have to ensure a confident VPN service. This is achieved either by appointing a personal VPN engineer or/and a backup system. Implementing a highly-available VPN service is just as a precaution to take control over the time that would otherwise be wanted for the recovery of a single VPN component.
Generally, implementing a highly available VPN system is to purchase two VPN hardware units and configuring both of them into a series connection with highly available pair using either a vendor supplied technology or a third party solution. With this system working practically, if one system fails, the other will respond immediately to provide back up.
The normal approaches for VPN communication failures are to install two different accessible hardware’s from two different service providers. It is more like an intelligent step as using service providers of different backgrounds removes the risk of any single operator carrying the fault that impacts each of the hardware. If one hardware fails, the remote users can re-connectivity immediately via a new one. The re-connectivity, however, can be done by the remote user itself who will be selecting an alternate VPN server manually.
Another approach would be to provide multiple internet routes to access VPN servers, although this approach is quite a complex bit of process.
Another alternative approach to doubling up hardware’s is to use hosted VPN service. It is a smart way to reduce the cost of doubling ups of hardware’s and also getting a high available VPN service. To use a hosted VPN in a high availability service, VPN server software needs to be installed on more than one existing windows server.
As hosted services use internet, business firms an install low costs internet circuits of multiple providers. This is just to ensure no internet connection breakdown or temporary failure. The hosted VPN services, however, provide a transparent failover for remote users with no discontent or reconnect required.
When considering high available VPN services, factors that need to be considered are complexity of the management, failover and recovery of the system and cost associated with these at a long term.
The Invisible Cell
Posted by admin in Cell Phone on January 30, 2009
What do you mean by cell? – If not a biology student, you won’t be able to answer this question. If you have a minimum knowledge about biology, you will start to block my ear with the nutty definition which you successfully memorized during the so called glorious student life!
Then if I ask another question, name one modern invention of science which is kept alive by an invisible cell placed outside of its body? Funny question! Rocking chair!? Hey man, not a joke at all, it’s our mobile phone, always with us… so lets know this funny thing…
Mobile cell is an area of radio coverage from one BTS (Base Transceiver Station), you will find in your area commonly, the high rise towers as piercing the sky!
It is the smallest building block in a mobile network (think it’s as an interlinked spider web!) and is the reason why mobile networks are often referred to as cellular networks. Typically, cells are represented graphically by hexagons (oh! It’s an area covered by six same length hands without any gaps in between!)
Usually these cells are of main two types:
1. Omni Directional cell: An omni directional cell (omni cell) is served by a BTS with an antenna which transmits equally in all directions (360 degrees).
2. Sector Cell: A sector cell is the area of coverage from an antenna which transmits in a given direction only. For example, this may be equal to 120 degrees or 180 degrees of an equivalent omni directional cell. One BTS can serve one of these sector cells with a collection of BTSs at a site serving more than one, leading to terms such as two-sectored sites and more commonly, three-sectored sites.
Typically, omni directional cells are used to gain coverage, whereas sector cells are used to gain capacity.
The border between the coverage areas of two cells is the set of points at which the signal strength from both antennas is the same. In reality, this line will be determined by the environment, but fro simplicity, it is represented as a straight line.
If six BTSs are placed around an original BTS, the coverage area- that is, the cell- takes on a hexagonal shape.
This cell planning begins with traffic and coverage analysis. The analysis should produce information about the geographical area and the expected capacity. The types of data collected in this issue are: cost, capacity, coverage, Grade of Service (GOS), Available frequencies, speech quality, and system growth capability.
The geographical distribution of traffic demand can be calculated by the use of demographic data such as: Population distribution, Car usage distribution, Income level distribution, Land usage data, telephone usage statistics, and other factors, like subscription/call charge.
So? Got idea about the invisible cell? …
15 Easy Ways To Strengthen Your Laptop’s Battery Life
Posted by admin in Laptop accessories on November 17, 2008
Did you ever have to experience anything like your laptop battery failing you when you needed it the most to stay alive & thereby you lost a deal or faced some serious problems? If you did then you sure had to curse your battery a bit. But all you can do is to take some measures to ensure that it does not happen next time.
Here are some tips that can help you make your laptop battery a bit more reliable.
1. the first thing that you might do to prolong the battery life of your laptop is to defrag your laptop regularly. As apple offers a better handle fragmentation so Apple users may not need this tip.
2. the monitor power should be made dim. As it will save the battery energy that might serve you at the moment of severe necessity.
3. the number of active programs that are not being used should be closed. You might run a number of programs at a time but running every program kills the energy of your battery. So closing down the unnecessary programs will help your laptop battery.
4. USB devices are a well known machine to kill your battery. Devices like mouse & WI-fi can eat up a lot of energy. Also do not charge mp3 players or ipods when your laptop is running solely on the battery.
5. You might think about increasing your RAM. This is a good idea because with increased RAM your laptop will be able to process the information using the laptop memory instead of using the virtual memory. When virtual memory is used it decreases the efficiency of the hard drive so it takes longer for the laptop to process the data & kills the battery life
6. CD & DVD drives consume a lot of your battery life. Just having a CD or a DVD inside your laptop can use a lot of battery power. So instead of using optical programs you should opt for virtual programs like Alcohol 120% as much as you can.
7. try to clean the battery contracts & keep it free from dust. Use alcohol to clean the metal contracts as it will make the battery more efficient.
8. Use a charged battery & ensure that it does not stay idle. If you are using a Li-on battery then make sure that it never gets completely charge less. Only the older batteries with memory can let to be charge less
9. Always opt to use the hibernate function instead of standby; hibernate mode helps your battery to save a lot of energy & if shut down then next time it will start from right where you left.
10. Ensure a cool temperature for your laptop both internally & externally. Try to use an air conditioned place to operate your laptop & get great cooling tips at LapTopMag.com.
11. to avail the most of the power options you should go to the control panel & select the “Max Battery” option.
12. Always arty to avoid using multiple programs while you are working only with your battery. Try to stick to only one program at a time. If you use a lot of different programs then you might end up with a dead battery before you are done with any of the programs.
13. Always try to ask as less as possible from your laptop. Gamming & watching a movie more often might just prove to be a bad idea for your laptop. So if your battery is all you have then choose correctly.
14. Replace your old laptop with a new model that is more energy friendly. Some manufactures are even offering batteries that last all day. Purchasing a newer more efficient laptop in place of an older one is a quick fix.
15. If you have an old laptop with memory effect battery then you will have to protect it by first fully charging & then fully discharging the battery at least once every three weeks.
Hope the ways narrated above will help you taking care of your laptop battery.
Things That Will Make Your Laptop Buying Easier
Of lately laptops & note books have become a commodity for every one’s use. It has become a part of the daily life & a part of what most people carry around with them. So if you are planning to buy a laptop you need to be aware of a few things that will help you to buy the laptop of your choice.
The first thing you should consider is the screen size of the laptop. The light & thin note books available in the market are generally 11- 13 inch & sometimes may be 14 inch.
The general note books will not contain optical drive as it is energy consuming and also will increase thw weight of the laptop. The battery life of laptops with optical drive is 5-6 hours. The thin laptops weighs up to 5 Ibs & the heavier ones with lager screens weighs 5 Ibs – 9Ibs.
Most of the light ones will have 1 GB memory which you can increase up to 2 GB later on if you want to. To be able to do that you need to ensure that your note book has 1GB memory installed & a 1 GB memory bay which is free.
Some times if you are lacking budget you might opt to get a notebook with a 512 MB which can later on be increased with 2 1 GB memories. But doing that would be a mistake because the installment of 2GB memory later on will cost you much more that what you could have paid for it if you would have bought it along with the laptop. More over the 512 will make your laptop slow & it won’t help your cause to make your laptop operating experience a good one.
As far as the processor is concerned you should opt to go with core2 duo or dual core. Though a bit more expensive than other processors but it will do more justice to the money you are spending.
You need not to be so choosey about the hard drive of the laptop. Most of the note books have a hard drive of 200GB which is enough for most of the users. But if you need more than that you can have hard drive of 400GB.
The use of graphics card in laptop depends on the user. Most of the notebooks offer a power efficient card that can merely be used as a DVD layback. Some will give you better graphics cards which might be ok for occasional gamming but not suitable for lengthy gamming.
Incase of operating system always go with the one you feel comfortable with. If you opt for Xp then 512MB is obvious while for vista 1 GB is enough but 2 GB is always preferred.
With so many new laptops being launched every day in the market if these few things are taken in to consideration then buying a laptop can be an easy task.
