Lots of goods seem to have come down in price in recent years. Take white goods for example. Appliances and electricals seem to be cheaper than ever before. However some things seem to remain stupidly expensive and it's hard to work out why.
Take printer cartridges for example. Most home computer users dread the moment when their printer runs out of ink and they have to go out and buy some refills. The manufacturers seem to cleverly price the printers really cheap and then make their money back on the ink cartridges. Even though manufacturers always recommend their own official refills, it is possible to use alternatives. Although even these seem pretty expensive when people stop and consider what they are. It's only ink after all.
The biggest mistake most people make when it comes to ink cartridges is to wait, run out, and then pop down to the local stationers to get some more. This is the most expensive way to replace cartridges. Which is why smarter people, looking for better deals on printer cartridges, shop online instead.
Finally a place where the customer can get good value on replacement inks. Take Internet Inks for example. Here computer users can find a huge range of refills for all makes and models at prices that are fair. Shopping online is safe, simple and secure. So people can stock up, pay a low price and never run out of ink again.
Customers don't have to accept the high mark ups and rip offs they are all too used to. It's time to stop paying over the odds for what is a necessity after all. Print documents and photos safe in the knowledge that ink doesn't have to cost a fortune after all. Internet Inks are leading the fight back against high prices and giving the consumer value for money.

Process Of Creating A New Directory In Linux
Computer users are aware that directories help you keep your files as well as your hard drive organized. Linux operating system users can have each of their directories attached with their own parameters. The parameters include knowing who has access to the directory, who has the permission to remove it and the permission to make changes in the directory. If you are not very comfortable using Linux and do not consider yourself a pro, you may contact an online computer repair service for assistance. The computer repair NYC service is exceptional in the way it deals with all PC issues.
Get started with creating a directory
Note that mkdir command used in Linux is one of the Bourne-Again Shell or BASH commands. This command is used when a new directory has to be created. Before using this command the Linux user must check which directory he/she is presently active in. This is done for getting rid of errors at a later stage if the users are in a directory where they do not have such command privileges. For checking this, you must use the pwd command and then press the Enter key.
The user must now type at the command prompt mkdir [directory] for creating a new directory. In place of directory command line operator, the user must type a name for the directory according to his/her preference. For instance, when the user is creating a directory called work, the user must type mkdir work. Note that this command will make a directory in the present working directory.
Now the user may use the –p command line parameter; this will create subdirectories in a parent directory. For instance, if a user is typing mkdir -p work/trainingprogram/office, he/she would be creating a directory tree that includes trainingprogram/office within the directory named work.
For creating a new directory in any other directory other than the present working directory, the users have to use the –p command line parameter in the similar manner of creating a directory tree mentioned above. However, in this procedure, the user must include a / before the first directory’s name. For instance, if the user wants to create an office directory in a work directory that already is present, he/she must type mkdir -p /work/office.
The Linux user can make many directories at once by using the mkdir command only once. This can be easily done by having a space between each of the directories that the user wants to create.
The users must know that in Linux operating system, a directory can be made in a directory that the user has access to and cannot be created in someone else’s domain. When you are using the mkdir command, be particularly careful about the spellings; if there is a spelling mistake, it will be difficult to locate a folder and also difficult to navigate to the folder later.
For any other help on creating new directories in Linux, you may consider a operating system support provider that can help you get rid of all your problems.

Difference Between A Switch And Router
Difference Between A Switch And Router
Switches and routers are special devices that enable you to make connections between and among computers, printers, peripherals, networked devices and/or other networks. A switch or a router has at least two ports into which you plug devices? cables to make the connection, but the similarities more or less end right there. What goes on inside these units is what distinguishes one from another. The terms are often used interchangeably, which is dead wrong, and using the devices incorrectly can result in a network that is just plain dead.
Switches do what simpler devices called ?hubs? do, but much more effectively, which is why hubs are decreasing in popularity. A switch will essentially ?learn? about the network ?traffic? that flows into and through it, and remember what the particular ?addresses? represent. For a basic example, a switch will sense traffic from Computer #1 arriving via Port #2, so it knows that any signals that are bound for Computer #1 will have to go out that particular port, as well. Whereas the older, simpler hubs send every signal everywhere, a switch only sends traffic exactly where it needs to go. Busy networks will run dramatically faster with proper switches installed.
Routers big and small
Routers are many orders of magnitude more complex than simple, straightforward switches, and there are many different models in many different form factors from which to choose. Routers can be anything from a small, paperback-book-size, four-port, wireless broadband router to the mammoth and powerful devices that are the traffic cops at the main intersections of the Internet itself. Without these ?intelligent appliances,? there would be no World Wide Web as there is today.
Simply put, a router is specialized computer that is programmed for its various important functions. It needs to be aware of the network data, as well as manage and manipulate it in various ways when required, while it also works tirelessly to route data both quickly and correctly. Today's broadband routers use their special firmware (built-in software) to camouflage or hide computers behind what's called a firewall. All routers have the ability to configure the handling of the network traffic through some kind of user interface running on the ?administrator's? computer.
Speed and connectivity
You will see a few terms that apply to both of these devices, the most important of which is network speed. Today's switches and routers are commonly capable of both current and ?legacy? (a fancy word for ?old?) speeds, and will often be labeled 10/100/1000. These figures refer to the number of megabits, or millions of bits, per second (mbps) the device can handle. You may have or see some older devices labeled with only one speed, which limits its use to devices operating at the same level. However, "gigabit" devices (1000mbps) are the most common now, and as 10/100/1000 devices they handle all speeds well.
A growing number of home and business networks have gone wireless, and the trend is accelerating all the time. The technical term for the wireless router protocols are 802.11b, 802.11g and the newest one, 802.11n. Wireless transceivers in these routers basically add more ?virtual ports? to the device. Wireless or wired, routers are standard equipment these days, and falling prices combined with increasing technological sophistication will see to it that they continue to spread.
There are some people who think that switches will eventually disappear as far as home use is concerned, although large businesses and web server companies will need them for a long time to come because of the varied connectivity requirements of their operations. As the so-called digital convergence continues, routers may end up being combined with cable or DSL modems to eliminate multiple pieces of equipment in the standard home or small-business network. If past is prologue in this field, then we can expect both switches and routers to get smaller, better, faster and cheaper all the time.
Switches do what simpler devices called ?hubs? do, but much more effectively, which is why hubs are decreasing in popularity. A switch will essentially ?learn? about the network ?traffic? that flows into and through it, and remember what the particular ?addresses? represent. For a basic example, a switch will sense traffic from Computer #1 arriving via Port #2, so it knows that any signals that are bound for Computer #1 will have to go out that particular port, as well. Whereas the older, simpler hubs send every signal everywhere, a switch only sends traffic exactly where it needs to go. Busy networks will run dramatically faster with proper switches installed.
Routers big and small
Routers are many orders of magnitude more complex than simple, straightforward switches, and there are many different models in many different form factors from which to choose. Routers can be anything from a small, paperback-book-size, four-port, wireless broadband router to the mammoth and powerful devices that are the traffic cops at the main intersections of the Internet itself. Without these ?intelligent appliances,? there would be no World Wide Web as there is today.
Simply put, a router is specialized computer that is programmed for its various important functions. It needs to be aware of the network data, as well as manage and manipulate it in various ways when required, while it also works tirelessly to route data both quickly and correctly. Today's broadband routers use their special firmware (built-in software) to camouflage or hide computers behind what's called a firewall. All routers have the ability to configure the handling of the network traffic through some kind of user interface running on the ?administrator's? computer.
Speed and connectivity
You will see a few terms that apply to both of these devices, the most important of which is network speed. Today's switches and routers are commonly capable of both current and ?legacy? (a fancy word for ?old?) speeds, and will often be labeled 10/100/1000. These figures refer to the number of megabits, or millions of bits, per second (mbps) the device can handle. You may have or see some older devices labeled with only one speed, which limits its use to devices operating at the same level.

Another VoIP Milestone: Over 1,000 Billion VoIP Minutes Used In 2006
Another VoIP Milestone: Over 1,000 Billion VoIP Minutes Used In 2006
In terms of VoIP minutes, estimated 1,079 billion minutes of VoIP traffic was carried by service providers worldwide in 2006. Of these minutes, 382.3 billion were local call volume, 614.4 billion were national long distance (NLD) call volume, and 82.6 billion were international long distance (ILD) call volume.
iLocus has been following the VoIP minutes data since March 1999. It is the only research group that has been able to consistently track such data and attribute the share of these minutes to service providers and vendors. In particular, iLocus pioneered the concept of attributing market share in traffic/minutes to equipment providers back in 1999.
David Quirk, CEO of C21 said: We at C21 Communications appreciate the annual report on VoIP industry, because it enables us to track particular market trends." C21 Communications is a Next Generation Network (NGN) solution provider and exclusive distributor of Topex products (Softswitches, media gateways and fixed mobile convergence equipment) in the UK.
In the carrier VoIP equipment market, softswitches and media gateways generated combined revenues of $2.2 billion, which represents about 24 percent growth over the previous year 2005. During the calendar year 2006, 36.9 million Class 5 softswitch licenses, 34.8 million Class 4 softswitch licenses, and 48.2 million service provider media gateway ports were sold in the market worldwide
In the area of Class 5 softswitch if the contribution from independent application server makers is included, then the actual Next Generation Network subscriber line licenses sold during 2006 comes up to 40.9 million. Out of the 40.9 million lines, an estimated 14.8 million lines were deployed for hosted VoBB application. The 14.8 million figure further splits into 3.4 million lines of hosted business Centrex/PBX and 11.4 million residential VoBB lines.
In the enterprise segment, the annual report reveals that in 2006 vendors shipped a total of about 18.3 million IP PBX end user licenses, and an estimated 8.5 million desktop IP phones. Desktop IP phone sales grew 38 percent over the previous year 2005, while the IPPBX market grew an impressive 52 percent year over year.
The VoIP industry report further reveals that that there were estimated 37.5 million VoBB subscribers worldwide as of end 2006. 16.5 million new VoBB subscribers were added during 2006. US added almost 3 million new VoBB subscribers during 2006. France and Germany added about 2.15 million and 1.16 million new VoBB subscribers respectively during 2006. Other markets which were aggressive in expanding VoBB subscriber base in 2006 include Netherlands, Canada, and Italy.
The research also showed that desktop IP phone sales increased by 38 per cent and the internet protocol private branch exchange (IPPBX) market grew by 52 per cent.
What Is A Wireless Network
What Is A Wireless Network
Having a wireless network opens up many possibilities.
Wireless networks provide an inexpensive and easy way to share a single Internet connection among several computers. This means you only need one modem, and you can add additional computers to the network just by plugging in a wireless card and turning them on. The new machines are connected to the Internet immediately.
A wireless network also lets you access files and printers from anywhere in your home. It allows you to synchronize files you have on your laptop with your home computer, and you can easily send files between computers as well. Using a wireless network to transfer files is faster than sending them via e-mail or burning them to a CD! Because printers connected to one of the computers on a network are shared by all the computers on that network, you can write documents anywhere in your home, press the print button, and collect the printed files from a printer that is connected to another computer.
If you are a game player, you have probably noticed that your games often have an option to play over a local area network or LAN. Wireless networks are LANs! This means you and your family can play these games together and do not have to be on computers that are next to each other to do so. Lets face it it is more fun to play against real people, and it is even more fun to play against people you know instead of strangers on the Internet. Your games will also play much faster over your LAN. Additionally, you can connect game consoles to the Internet and begin playing these games online. It is much easier to experience online play through an Xbox or PlayStation 2 that is connected to a wireless network than have to use a modem!
Wireless network connections are always on. This means you can connect to the Internet whenever you want without waiting for your modem to dial in. Laptops can be carried from room to room, and they will always have access to the Internet. Since wireless networks operate without the need to log in, you do not need to set up usernames or passwords.
The single greatest thing about a wireless network is that it is, well, wireless! The biggest reason to have a wireless network is because it eliminates the need for costly, ugly, and dangerous wires trailing all over your house. You can use your computer in any room you want no more being trapped near a phone outlet or walking over that tangle of wires in your home. The cost of getting enough Ethernet cables can add up, and sometimes, you may even have to make holes in your walls to set up a wired network. If you are renting, of course, this is impossible. With a wireless network, you do not have these problems - you can even use your computer outside if you want! And if you move, there is no need to disconnect and pack up all those wires, and you no longer have to examine all the wires for damage whenever your Internet connection goes down.
You can see how having a wireless network can simplify your life.

Denial Of Service Attack
Denial Of Service Attack
A router can only handle so much information coming into it at one time. Every machine has its limits and routers are no exceptions. Well, when the nasty trend of denial of service attacks started early this century, routers were unprepared for them. As they began to understand what was happening they began to compensate for the problem. But there was still a way around it. To understand this we first have to understand what a denial of service attack is.
A denial of service attack is just as it sounds. It is when someone prevents the router or routers from servicing the network. The question is, how do they do this? As previously stated, a router can only handle so much information coming into it to be routed at a time. If too much information starts coming in then the router gets overloaded and can't forward the information fast enough. Ultimately, what happens is this slows the network down to the point where nobody can access it. In a denial of service attack, which is a deliberate attempt to cause this problem, a person will send an enormous amount of information from one computer to the router at one time. Eventually this will effectively shut down the network. The reason is because of the trickle down effect. Once the main routers start to get overloaded they start to send messages to the rest of the network that the connection is full. These messages start to cascade through the entire network until all the pathways in the network are full and nobody can communicate with any server on the network.
When companies and web sites began to understand what was happening then started to put safeguards in place. They would put checks in the router software to see if a large amount of information was coming from one IP address. If so, then it simply discarded the information and didn't attempt to pass it on. It seemed that the problem was solved. Not so.
Hackers began to figure out that if they send this enormous amount of information from multiple computers or IP addresses, the routers would have no way of knowing that a denial of service attack was in progress because it would see all this information coming in from multiple locations. Ultimately again, the network would effectively be shut down.
In response to this, manufacturers of routers have placed additional safeguards into their routers to simply check for unusual traffic. The problem with this is that in some cases there is a large amount of traffic that is normal, like in the case of a news site being hit with an overload because a major breaking story hits the airwaves.
