Protect Your Wi-Fi From Unauthorized Access

Computers  are connected through wired or wireless media. In wired media STP or UTP cables and devices like hub, switches, routers etc. are used. Now a days people are opting for wireless networking more than wired networking. In wireless networking  radio waves and microwaves are used to attach computers. Wireless network also called Wi-Fi  network. The first wireless card was 802.11b but the standard are upgraded day by day.  In companies, universities,  libraries, hotels, airports wireless network are more in demand and more feasible than the wired network. Telecommunication network is a bigger network in wireless networking eg. Mobile Phones. There are  many wireless devices that are used like wireless Access Point, Wireless  LAN Cards, Wireless Adapters, Wireless Routers etc. There are many types of wireless networking like Wireless PAN,  Wireless LAN, Wireless MAN etc.

The  wireless network has many advantages as compare to wired networking, there is no need to put cables across the walls of homes and offices, it helps maintaining the beauty and cost/time incurred on drilling/repairing the walls is saved. We also save cost incurred on network cables, it is less time consuming and requires less technical support, easy to set up than wired media. It is accessible anywhere within its range, hence you need not to find a network I/O to get connected, take your laptop within the range of the wi-fi network and access the internet or other resources.

The only problem of a wi-fi network is its limited range and larger networks are affected by weather as well. If you want to setup wi-fi for a large area say college campus etc. you have to add in more access points.

If you are planning to setup a wi-fi network at your home or office, you must address the security issues as someone may intrude into your network and access your valuable information or may send emails using your IP. In the recent incidences, terrorists used the Wi-Fi network of neighbors to communicate with each other and sent threatening emails to people. Hence, ensure that your Wi-Fi is fully secured and nobody else is using it except you.

You can  protect your network with firewalls, proxy, VPN and WEP key etc. In WEP (Wired Equivalent Privacy) we give a security code  that secures our network and unauthorized person can not access the network. WEP comes with 64bit, 128bit , WPA-PSK, WPA–TKIP security features. For better security, keep changing your WEP key and administrator password, router password regularly, filter out the MAC address and use firewalls at every computer in a network and lock all the folders and make access lists.  Access list provided extra level security while giving instructions to routers and filter the MAC addresses. Switch off the routers and other devices when not in use. But the above securities measures can not be implemented in the public areas like libraries, hotels, airports etc.

On the laptop’s hardware to protect intellectual

First of all, or to talk about notebook hardware maintenance skills. Mainly divided into the following areas: 1, liquid crystal display. LCD screen should be a whole notebook of the most important output device, and the most precious parts, and the general costs will account for 30% of the entire laptop around, so the maintenance of LCD screen should be of paramount importance.If the prolonged use of laptops, then the brightness of the screen will be dimmed, the screen will be yellow, which is liquid crystal display aging is a normal phenomenon. The pace of aging is that we should be concerned about, and would generally be used with the liquid crystal display duration is related to the notebook, despite the portable nature of the advantage, but it can not boot the desktop, like a long time, on the one hand it with the notebook cooling related to the life of another liquid crystal display also has a great impact If the current desktop with LCD monitor, it is recommended do not let it work long hours. A good notebook computers, such as Apple and Sony, on the LCD display will have a power-saving mode is set, that is, PA-1600-06D1 PA-1600-06D2 dell 19V 3.16A 60w 5.5mm*2.5mm adapter laptop battery users do not operate, the screen will automatically darken. In general this technology for use on mobile phones are more on the screen.If the outdoors, the one you can save energy, and secondly, can also protect the LCD display. Let me say the habit of other problems, not to decorate Jiangshan LCD screen, if the display is dirty, should not refrain from hand to erase, it is best to use high-grade cloth or swab the eye lens paper, scrub with a special cleaning fluid, not water, because the water to enter the LCD screen will lead to short-circuit. For the protective film, the one hand, it can display can be away from dust, fingerprints and grease, but it will also reduce the actual LCD display, you do not depends on your own. Also to note is not to put heavy pressure in the notebook above, as well as harmony is to turn on the laptop when the laptop is still click it, broke the province to connect with.

Second, the battery issue. Notebook greatest advantage is that we can carry, and this feature is no doubt a great link with the battery, without battery, you take only a high-tech scrap, if your battery needs to charge less than half an hour of the , would you feel depressed, Oh, now Laijiang Jiang battery maintenance. Now the notebook are normally used for lithium-ion batteries, while the nickel-metal hydride batteries and nickel-chromium batteries have basically no longer in use, the difference is that lithium-ion battery memory effect significantly less than the other two. Although the lithium-ion battery memory is not obvious, it can easily charge and discharge, but it is still free to charge and discharge will affect its life, so if there are no special circumstances, or try to avoid arbitrary charge and discharge. For new notebook, the first few charging, it should take note of this in mind: as far as possible to use laptop battery will not turn on the extent, but can not use a bit of non-left (that is, the total discharge), and then shutdown state (not to side computer side of charge) under the battery fully charged, so repeated several times, so you can say that the battery power to play the greatest potential, while the future as long as no arbitrary charge and discharge, then the lithium-ion battery memory effect would not be great impact on the battery block, if possible, please also carried out monthly for a full charge the battery discharge. Another said that the attention to other matters under the bar, if you use an external power supply whenthe AC is best to unplug the battery, or battery a long time in a fever state, their life will be affected. Make full use of clean electricity (voltage not too high or too low), PA-1750-01 liteon 19V 3.95A 75w 5.5mm*2.5mm adapter laptop laptop battery be careful not to put the notebook power adapter and power appliances (such as air conditioning) connected to the same power strip, the reason is very simple, high-power electrical appliances will be open the formation of high-voltage transient. If the battery is not a long time, please save it in a cool place (40 degrees seems to be more appropriate) to weaken its internal self-passivation reaction speed; please charge and discharge at least once a month to ensure that its activity. For notebook inlet of such accidents, the first thing to do is remove the battery, the natural dry it with the laptop, and then sent to a professional repair service center.

3, shell. People rely on clothes, books but also beautiful. With the use of more and more time, books shell will gradually be worn, especially Sony, Samsung focus on these designs beautiful books and easier to become a major Erhualian the contrary, IBM this Dalao Hei, a long time does not there will be great changes. Therefore, we have to advance the prevention of the appearance of wear and tear, and now on the market you can buy a special notebook transparent protective plastic mold, yet without losing beautiful, well protected roof can also be scratched. In addition to the front, there are side, in fact, more vulnerable to wear and tear the side, long and arm wrist wear, if it is summer, but also suffered the erosion of sweat, even though no matter how good the material can not help but frustrating way, I propose to put some labels up , both without losing beautiful as well as reduce wear and tear shell. In addition, when using the laptop off the best metal jewelry like watches, so as not to scratch hard objects notebook shell, Oh, seems to be too careful, be careful driving have thousands of years ships Mody. . . . .

4, the hard disk. Whether desktop or laptop, hard drives are very precious parts, prone to problems. Compared to desktop hard drives, notebook hard drive also will be more shock some, but this does not mean that it is engaged in is not bad, took it when the basketball, or should avoid unnecessary vibration. Especially the boot time, it is best not to move notebook.

5, CD-ROM. Most laptop or standard CD-ROM drive, for size considerations, CD-ROM books are doing very thin, and the discs are generally stuck in the shaft on, so try not to use low-quality CD-ROM, or irregular, and that is very easy to damage laser head. If you can, on a regular basis with a special CD cleaning tablets rinsed laser head. laptop battery Also not to drive when the CD with the books, on the one hand drive work will generate substantial heat on the overall cooling disadvantage, another drive long-term work on the laser head also has a great impact on life expectancy, so they should not stay in the CD-ROM disc inside. If you want to books when the CD, is also feasible, although it seems to me bit of a waste, then put your favorite CD on the hard disk made of a virtual CD-ROM, thus reducing the heat, there should be better than the life of the hard disk drive to be longer.

6, mouse, keyboard. Books of the built-in mouse there are two: One is the pressing sense of style, the other is the touch-screen. The former intensity had no control, finally operation, which fingers are too dry and not easy to operate.The solution: the former its own experience of it, to teach and taught not, some people born with heavy-handed; the latter does have a way, because touch-screen is a layer of hair surface similar to the PVC material, first of all try not to get it to the dirty, you can always wipe the surface with a soft cloth, if the finger is very dry, on the first of a hand wash it, to minimize the friction between the two. For the keyboard, I am afraid the problem is most likely to encounter the danger of being worn and keyboard keys inside is dirty. Is also no good solution, otherwise only the stickers, and usually pay more attention to look at cleaning it, cleaning dirty or only copies, and he will not out, and get good after-sales service centers. Another approach is to use an external mouse and keyboard, though not very easy to carry, but can still at home, and how to say, or from a traditional mouse with convenient, books of the “small” is still not as good as the standard keyboard, large keyboard playing from comfort.

Protect Yourself from Computer Viruses

No matter what you do, you are bound to run into a computer virus at some point. These are nasty little customers, and can leave your computer running at a snail’s pace, or can crash it altogether. The very bad ones can erase your data and render your machine useless. Even worse than this, they can get hold of your passwords and credit card details.
There are great antivirus software packages out there, but at times, even they can fail to protect your computer. This is why you need to keep an eye on things, and always remember to run a virus check.
If you have software like Norton’s, you should get automatic updates. Always make sure you take the time to download these. This information may be vital to protect your computer from a newer type of virus.
Computer viruses are always evolving, and those who produce them are always looking for new ways to infect your computer. If you have broadband Internet service, you should know you are at the highest risk for getting a virus.
If you don’t have virus software on your computer, you can find a free virus check on the Internet. There are quite a few that will scan your computer for viruses, but most of them stop there. I remember spending two days looking for a virus check that found the viruses and then took care of them. Most places will scan your computer, show you what you have, and then tell you that you must buy the their software to get rid of them.
This trick is quite common, and also happens with many free spyware and malware scans. You might want to read the fine print before you put your computer through a lengthy virus check only to be told you must then buy the product. Some come with a free trial period, and if they offer that, you may want to do it. In many cases, you may like the service so much that you buy it. This is the best way to find out if a virus check is worth your money.
Another thing to remember when running a virus check is to look into customer support if you choose to buy. You want a company that offers you online support if you run into trouble. Many viruses can be removed by software, but on occasion, some may need to be manually removed. This is often a long and complicated procedure. When you have to do this, it is nice to know help is at your fingertips.

How to protect your wireless broadband connection

At first glance having your wireless connection hijacked is not as improbable as it may seem.

Regardless of whether your wireless connection is liberated by a balaclava-clad burglar during the night or a chap on his laptop sitting in a white van outside your house on his lunchbreak, the end result is the same: a high bill or, even worse, a ‘policeman’s knock’ at 5am.
