First, here’s the rundown of some of the terminology I’m going to use in this article –
Inbound Links – Links coming into your site
Outbound Links – Links leaving your site
Cross Links – Links that you have “traded” with another site (i.e., they’ve got a link from their site to your and you’ve got a link from your site to theirs)
PR (Page Ranking) – Google’s measure of how “important” your site is
SEO Is Not Dead
Ok, now let’s talk about what you really want to hear – how to get those coveted 1-10 ranks for your keywords. Remember this - SEO is not dead. In fact, it is very much alive and important. The first thing to do in order to raise your site rank is target specific keywords. I say specific, because you need to target “key phrases,” meaning more than one word keywords. Some people use the words interchangeably (me included) so just ignore one-word keywords altogether. You will waste your money if you shoot for these, because chances are, there are other, MUCH larger companies who already have you beat, and will continue to have you beat unless you’ve got a bottomless wallet.
Check Out Your Competition
Take this example, for instance, if you sell computers, you should not try to optimize your site for the keyword “computer” or “computers.” First, think about all of the businesses that do ANYTHING with computers. Yeah, that’s a lot. They’ll all show up if you search for “computer.” Now try to think of who would show up at the top of that list. I’ll make it easy, it’s Apple, Dell, Computer World, Computer Associates, IEEE, Computer History Museum, Webopedia, ASUSTeK, WhatIs.com, and HP. I’m going to go out on a limb here and say that I 99.9

Understanding the Components of a Home Network
Home networks are becoming more common. People want to be able to share a single broadband Internet connection to several computers in the house. There are many different devices that you can use to make up your home network. If you have never heard network terminology device names like router, hub, etc may seem confusing.
The purpose of most of these devices is to control how the network passes around information. This information is sent in the form of "packets". I will refer to the term packet several times in this article. It simply means the data that the network is transporting. I will now explain the purpose of the major components of a home network.
What is a Hub
A hub is a device that has several Ethernet ports on the back of the device. One of these ports will likely be labeled “Uplink”. This port allows you to connect multiple hubs together, if you run out of ports on your hub. If you do not have an uplink port on your hub, the hub cannot be easily extended if you run out of ports.
A hub is a device that attaches multiple computers on an Ethernet network. If you have a number different computers that you want to connect together, you could connect each to the hub. Any packet that is sent out by any computer on the network will immediately be transmitted to the other computers. Each computer will determine if the packet was really intended for it, and filter out packets that were intended for other computers.
You really should not use a hub in a modern home network. You should always use a switch in place of a hub. Switches will be discussed in the next section.
What is a Switch
A switch is a device that has several Ethernet ports on the back of the device. One of these ports will likely be labeled “Uplink”. This port allows you to connect multiple switches together, if you run out of ports on your switch. If you do not have an uplink port on your switch, the switch cannot be easily extended if you run out of ports.
A switch serves the same function as a hub. It allows you to connect multiple computers together, so that they can exchange packets. However, a switch is much more efficient than a hub. A switch will only send Ethernet packets to the computer that the packet was intended for. Because of this you should always use a switch in place of a hub.
What is a Router
A router is a device that has several Ethernet ports on the back of the device. One of the connectors will be labeled WAN. You should connect the WAN port to the Ethernet connection on a broadband source, such as a cable or DSL modem. The other ports on the router can be connected other computers or switches/hubs that will share the WAN connection.
Routers allow you to share your broadband connection with multiple computers in your house. Rather than connecting your computer directly into your cable or DSL modem you connect the router to the cable or DSL modem. Now any computer that you connect to the router will have access to the Internet.
If you run out of ports on your router you can always connect an additional switch to the router. To connect a switch to a router simply connects the switch’s "uplink" port to one of the routers Ethernet ports. Of course, don’t connect to the router’s WAN port. The WAN port should only be connected to something such as a cable or DSL router.
Some routers come with additional features installed. Most routers also include a firewall. Firewalls are discussed in the next section. Some routers will also include a wireless access point (WAP). The WAP allows you to use wireless devices, such as wireless laptops, with the Internet.
What is a Firewall
A firewall controls traffic flow between your network and the Internet. A firewall can be either hardware or software. Windows XP SP2 or higher includes a software firewall. A hardware firewall is included with most routers.
A firewall is a very good idea. It can protect you from inbound virus attempts. By inbound virus attempt I mean other computers that will connect to your computer and attempt to infect your computer. You do not want to run a computer directly connected to the Internet, without a firewall. There are just too many other computers out there that can connect and infect you without you even noticing.
What is a Network Attached Storage (NAS)
A network attached storage device is s device that allows a hard drive to be shared across the network. This hard drive is NOT attached to any of your computers. It is simply made available by the NAS. This can be a convent way to add a hard drive that can be accessed by several computers on your network. The other common way to add a network hard drive is to simply share a folder on one of your computers. However, with the NAS, you do not need to keep one of your computers on at all times.
There are two types of NAS commonly available. The first type comes with a build in hard drive. The second accepts a USB or Fire wire external hard drive. The advantage to using a USB or Fire wire hard drive is that you can upgrade the hard drive if it ever were to become too small.
What is a Print Server
Just like you can buy a device to allow you to share a hard drive, you can do the same with a printer. A print server connects directly to your printer. Your printer is then shared to all of your computers on the network. This is convent because you do not need to leave the printer hooked to a computer, which must be turned on to print.
Conclusions
As you can see there are many different components. Perhaps the final component that I ave yet to mention is the cable. These components are connected together with CAT5 Ethernet cable.

Automation: an Ingredient of Success
As is normal in the world of computers things change rapidly and there’s always a bigger, better piece of software or hardware waiting in the shadows patiently for its chance to dethrone current technology. This is perhaps even truer when dealing with technologies surrounding networks. Though it’s been in existence for some time aspects of IT automation are just beginning to take foot within businesses.
When it first began to make it’s rounds in the business world, IT Automation was extremely expensive to have implemented and the technology was in an obviously unproven state. As time went by and the technology advanced more businesses began to take notice and begin implementing things like Run Book Automation and ITIL automation. These businesses quickly discovered that implementation of such things freed up not just network resources but human resources as well.
Prior to implementation the majority of businesses whom relied on their networks for business were frequently forced to dedicate one or two individuals to a network for the sole purpose of tracking down bugs and then manually create patches for those problems. This naturally consumed payroll and did not allow talented individuals to assist in the creation of new applications, perform alpha and beta testing, and even keep things running smooth for those in the company who used a computer. As it became known that automation would free up these types of resources and allow the network to patch itself this technology really began to garner attention from businesses that may have once been apprehensive about adopting a new technology.
These days the majority of companies be them small or large have implemented some type of automation. Some have begun to use services like ITIL Management while others still have gone to full automation and streamlined their IT staff considerably, saving their company both money and time. In fact those companies who do not plan to automate to even a small degree should take heed and learn from those who’ve already chosen that path. Data Center Automation has become such a powerful tool that those that choose not to automate often find themselves struggling to keep applications online and running properly and generally have no choice but to employ an unnecessarily large IT staff. In many cases these companies have failed and are no more however it’s never to late to begin the automation process.
As with all things once it approaches commodity status and is no longer the new thing prices drop, healthy competition takes root, and there are endless choices both in terms of services and cost for entrepreneurs and IT professionals to consider. Most experts predict that the majority of networks will be completely autonomous by 2016 and while that’s difficult to argue, it may happen much sooner should the technology continue on the road it’s on.

Setting Up a Small Business Computer Network
A computer network setup is an integral part of every organization today. The linkage of the different computers in the office space helps in the growth of the business by saving time and money. It speeds up the work pace and invariably saves a lot of time. Each office would have its own specific needs. One can approach network consulting firms with their requirements and have a computer network setup that caters specifically to their needs. Your computer must be used to its full potential and all your needs should be met with a good computer network system in place.
An effective computer network would mean a good network design to begin with. The network consulting firms can also suggest the best possible network design as per the nature of the job of the enterprise and the role of the computer network system in the work area. There are various kinds of computer networks like the LAN (Local area network) to WAN (Wide Area Network) and various other types. Each has its own particular role and use and the right one can be chosen depending upon the field of functioning. One can even have a computer network setup that is wireless. A wireless system is a more practical solution in recent times as people can be connected and still have the option of roaming freely with their laptops. A remote access arrangement is also a good networking option. In case of the traditional wired network one should be certain that the cabling done is of superior quality or else the problems that you may end up with are plenty. A system integration firm would be the best option to setup a good network in the office space.
The system integration firm will help integrate a new setup with the already existing setup in the organization. This would help save money for the company as you may not need to do away with the old network as the professionals would be able to find a way of combining the new technology with the already existing one. Apart from the different systems existing in the company it can all be brought together under one umbrella and this would help in extracting the complete picture all at once. All the subsystems are held as one and the integration process makes it as one.
A computer network that is setup with the aid of network consulting agents, using their expertise in putting up a network system in place helps in making the operation of the company smoother. An effective system integration process adds to the benefits of the computer network. All this put together triggers the growth process of the company. There are various firms offering services of network design and system integration. Do a proper study before hiring the services of any. Since this involves thorough knowledge and expertise of all the systems in place, you have to be certain that the job is assigned to a competent firm with sufficient experience and knowledge behind them.
