Commonly simplified as DSL, Asymmetric Digital Subscriber Line (ADSL) is technology for high-speed Internet access. It uses existing copper telephone lines to send and receive data at speeds that far exceed conventional dial-up modems, while still allowing users to talk on the phone while they surf. By contrast, DSL is typically not as fast as cable Internet access. It is generally well-suited for moderate gaming, computer-aided design, streaming multimedia, and downloading large files.

What Is DSL
The full form of DSL is known as the digital subscriber line, which consists of various different technologies that provide an internet connection to a computer network using the DSL.
The digital subscriber line , or most commonly known as the DSL, involves the use of the pair of copper phone lines using the wiring networks, these also comprise of a main switch which has special hardware to relay the internet signals to the other end of the user. A continuous digital connection network can be achieved using this technology.
The DSL technology is purely based on digital composition and thus there is no use of the digital to analog conversion for the internet transmission as required in the previous modems of the traditional times. The DSL system does not use the frequency spectrum of the audio in the phone, because it requires the frequency above that which means that the telephone can be used while the internet connection is still on.
The speed of the DSL system technology is incomparable to any other internet connection provider, previously used. If compared, the DSL wins over 50 times faster inter speed than the general modems used and is about 12 times faster than the ISDN connection. The reason behind this is that the DSL system used different frequencies for the encoding of the data, which allows a much faster internet speed. Another factor which contributes to the high speed of the DSL is that it is not a bus technology because of which its offered bandwidth is much more consistent than the other types of modems which provides the same bandwidth to multiple users.
However, the only conditions that can affect the transmission speed are the wiring conditions and also to some extent the distance limitations.

Internet tools
Internet tools are basically used so as to make the internet use much easier via some of the applications specially made for a particular internet business.
These tools are advanced and custom-built for the development of the internet, so that the optimal management can be achieved both in the informational and communication solutions. These tools are also available commercially.
Different networks are compatible with different internet tools, as described further.
The tools related to the networking of the TCP/IP most widely used is the "Fifi Ping »"
The Ping is actually used for the basic inquiry to determine whether the host which is governing the internet is alive and transmitting information and signals or not. The ping tool performs this task by sending data to the host of the network used for the internet so as to see the response and the time period required to achieve it.
The internet tool of the "Icestorm NSLookup »" is used to convert your personal domain name into an IP or the internet protocol address, like the form (216.122.237.109) it can then be used for exactly the opposite task, but the DNS server has to be queried for that.
The other internet tool related with the Internet protocol "Dig DNS Check »" is used to gain information from the DNS servers using the domain information groper of the DIG.
The internet tool of the "logic Host Check »" is used by the network of TCP/IP to perform several different tasks and tools of the network in one single host.
What is Internet
he internet in simple terms is a network of the interlinked computer networking worldwide, which is accessible to the general public. These interconnected computers work by transmitting data through a special type of packet switching which is known as the IP or the internet protocol.
Internet is such a huge network of several different interlinked networks relating to the business, government, academic, and even smaller domestic networks, therefore internet is known as the network of all the other networks. These networks enable the internet to be used for various important functions which include the several means of communications like the file transfer, the online chat and even the sharing of the documents and web sites on the WWW, or the World Wide Web.
It is always mistaken said that the internet and the World Wide Web are both the same terms, or are synonymous. Actually there is a very significant difference between the two which has to be clear to understand both the terms. The internet and World Wide Web are both the networks yet; the internet is the network of the several different computers which are connected through the linkage of the accessories like the copper wires, the fiber optics and even the latest wireless connections. However, the World Wide Web consists of the interlinked collection of the information and documents which are taken as the resource by the general public. These are then linked by the website URLs and the hyperlinks. Therefore World Wide Web is one of the services offered by the whole complicated and huge network of the internet.
The use of IP in the Internet is the integral part of the network, as they provide the services of the internet, through different layers organization through the IP data packets. There are other protocols that are the sub-classes of the IP itself, like the TCP, and the HTTP.

How do they all work together?The following buying guides for each component will hopefully clear up the confusion on what you need to know to choose the best parts for your custom gaming build. Or if you're looking for specific part recommendations you can skip to the Recommended Gaming Desktop Computer Builds.Choosing the Best Motherboard For Your Custom Gaming PC
This article is here to help you choose the best motherboard for gaming. The motherboard is one of the most important components in any computer, and it can make or break a system.
You can have the best CPU, RAM, and graphics card in the world, but without a quality motherboard at the core of your system you won't be getting anywhere fast.
We will look at the various factors you should take into account when choosing your gaming motherboard, to ensure that you choose the best motherboard for your needs and one that is compatible with all your other components.
If you think of the processor as the brain of a computer, then the motherboard could be described as the heart and/or central nervous system. The motherboard represents the core of a PC and is responsible for relaying information between all the internal components. In other words, it’s the hub of the computer, where all other components connect to.
Since the motherboard is so crucial to your system, buying the best motherboard you can afford is a good investment if you want a gaming system that will last. The following guidelines are here to help you make a more informed decision on your gaming motherboard choice:
CPU Compatability
The first thing you need to be aware of when choosing a motherboard is compatability with the CPU you plan on using. A motherboard will generally only support either Intel or AMD CPUs, and only certain models too.
Checking for compatability between a particuilar motherboard and a CPU is very simple, all you need to do is check to see if the motherboard and CPU both have the same 'processor interface'.
RAM Compatability
The motherboard you choose will dictate the type and amount of RAM you can have. These days you will want to get DDR3 RAM, and at least 4GB for the best gaming performance to play the latest games. So ensure your motherboard will support this type and amount of memory, but most boards these days will so it's very rarely an issue.
Ports, Slots, and Other Features
If you need extra PCI ports for other cards then make sure your motherboard has this. You should also consider the number of USB ports you need, and whether you need a Firewire port (used for video capturing and editing).
Also, be sure there's enough PCI-Express slots for your needs. You will need a PCI-Express slot for your video card, or two slots if you are going to install two video cards in your machine. If you decide on getting a dedicated sound card then you will need another PCI-Express port for that too.
On-board Audio VS Dedicated Sound Card
Most motherboards will come with built-in audio so getting a dedicated sound card is completely optional. I would recommend investing in a sound card if you want the very best experience from your games, or if you want to take full advantage of high quality speakers or headphones.
For music producers and those doing video and audio editing it's a different story, and a sound card is necessary as the on-board sound provided by typical motherboards won't cut it. If you want to learn more about choosing a dedicated sound card for gaming or other purposes check out How To Choose The Best Sound Card.
Tips On Buying Your Motherboard
When you're choosing the best motherboard for your gaming PC it's wise to think ahead a little. If you want your motherboard to last you a while then I would recommend you choose a decent quality board that has been released recently.
Since the motherboard is such a critical component to your gaming PC, in general I would recommend buying the best board you can afford. Some of the most-trusted motherboard manufacturers for quality and reliability are ASUS, MSI, EVGA, Intel, and Gigabyte to name a few of the best.

IP address (Internet Protocol Address)
The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet.
When you send or receive data (for example, an e-mail note or a Web page), the message gets divided into little chunks called packets. Each of these packets contains both the sender's Internet address and the receiver's address. Any packet is sent first to a gateway computer that understands a small part of the Internet. The gateway computer reads the destination address and forwards the packet to an adjacent gateway that in turn reads the destination address and so forth across the Internet until one gateway recognizes the packet as belonging to a computer within its immediate neighborhood or domain. That gateway then forwards the packet directly to the computer whose address is specified.
Because a message is divided into a number of packets, each packet can, if necessary, be sent by a different route across the Internet. Packets can arrive in a different order than the order they were sent in. The Internet Protocol just delivers them. It's up to another protocol, the Transmission Control Protocol (TCP) to put them back in the right order.
IP is a connectionless protocol, which means that there is no continuing connection between the end points that are communicating. Each packet that travels through the Internet is treated as an independent unit of data without any relation to any other unit of data. (The reason the packets do get put in the right order is because of TCP, the connection-oriented protocol that keeps track of the packet sequence in a message.) In the Open Systems Interconnection (OSI) communication model, IP is in layer 3, the Networking Layer.
The most widely used version of IP today is Internet Protocol Version 4 (IPv4). However, IP Version 6 (IPv6) is also beginning to be supported. IPv6 provides for much longer addresses and therefore for the possibility of many more Internet users. IPv6 includes the capabilities of IPv4 and any server that can support IPv6 packets can also support IPv4 packets.
