Network Interface
Feb/090
In the late 1960’s as large college universities and several research labs gained an ever increasing amount of computers, the need for interconnections that worked at high-speed was great, and the pressure was on. It was not until the mid 1970’s that an answer to the demand was created, they called it LAN.
LAN stands for Local-Area Network, with the ability to cover small areas, such as a home or office or group of buildings (schools, warehouse, etc.), LANs have higher data-transfer rates, smaller range and do not require licensed telecommunication lines as opposed to WAN (Wide-Area Network). ARCNET and Token Ring were two LANs that were widely used in the past. Ethernet and Wi-Fi are two of today’s most common LANs.
A LAN is an important component to gamers. By setting up a LAN, gamers can link together their computers and play with or against their friends. Games, such as “Diablo II” and “S.O.C.O.M.”, allows gamers to cooperate together in a team while either on line or while their computers are connected by LAN.Games, such as “Unreal Tournament” and “Starcraft”, allow gamers connected by the internet or a LAN to work as a team or to compete against each other.computers are usually linked by what is known as a Cat-5 cable to a HUB; and the HUB acts like a mediator. The Cat-5 cable connects to the back of the computer through the Ethernet port on the Network card, network adapter, LAN adapter or NIC (Network Interface Card). A network card operates on both the physical layer and the data link layer; it allows a low-level addressing system, using Mac Addresses, also known as an IP address, and physical access to the networking medium (the HUB). Not all LANs are the same; some use cables while others are wireless.
While other network technology exists, since the mid 1990’s, the Ethernet network card has been leading the crowd, due to low cost and easy integration and use. A unique 48-bit serial number is on every Ethernet network card, stored in the ROM; the serial number is your computers Mac address. The Mac address for every computer must be unique; otherwise only one computer with a given Mac address could be on line and connected to the LAN at a time. The Institute of Electrical and Electronics Engineers is responsible for each unique Mac address getting assigned to vendors of interface controllers; this is so no two network cards share the same Mac address.
At one point network cards were expansion cards that had to be plugged into the motherboard. Most new computers have the network card built into the motherboard; some may even have two ports built in so the computer can be connected to multiple networks. Some companies have started using optical fiber instead of Cat-5 cables or USB cords, because optical fiber is immune to electromagnetic interference. Optical fibers are made of glass or plastic, instead of metal, and carry light along their full length. The electrical signals sent along the optical fiber degrade less during transfer than signals sent along metal wires (Cat-5 cables and USB cords).

Domain Name
Nov/080
What should I know before you register a domain name?
I was thinking of registering a domain name, and wanted to know what kind of things you should know before proceeding. I know XHTML, CSS, and some Java Script, but apart from the site should really know any encryption or practice security? There is also some domain registrars you recommend? Perhaps one that includes accommodation, or vice versa.
I recommend one of these: http://www.webhostingtable.com/ Powweb currently has the best deal. Standard price is $ 7.77/month ($ 93.24/year), but have to sell the 50% now. Disk space: Unlimited Bandwidth: Unlimited domain names Unlimited domains and subdomains Price: $ 3.88/month ($ 46.56/year) Your hosting plan includes site builder, so you can create your site with only drag and drop (no programming), or you could install Wordpress (easy, click install from your control panel), choose a theme you like, and start adding content. Or since you know XHTML and CSS you can build the site itself. As for the security work is your host. They are responsible for the safety of servers.
How to Buy a Domain Name
Network Switch

There are several large network hardware vendors out there, and it can often be confusing to decide which brand to buy. Do you want a Cisco router, a Juniper router, or a Nortel router? What brand network switch or sever should your company purchase? Each specific company provides a huge amount of detail/advertising on why you should pick their solution. I decided to congeal some of these product details and provide an overall list of features that your company should be looking for in their enterprise networking hardware.
No matter what type of business vertical you are in, or where you are running your company from, networking hardware is a critical aspect of your business. The five key features your network hardware and network infrastructure should provide are:
- Simplicity: A network product and OS that is extremely simple, logical, and easy to operate will make everyone’s life easier. Network hardware that is simple in installation and execution, but provides the infrastructure for complex company communication, is a must have.
- Security: Your enterprise data is your company’s most valuable resource. Whether it be client data, financial data, or intellectual property data, it is extremely important that your network provides the protection and access control for this data. Your brand of Network hardware can mean the difference between an occasional security breach and a perfect record of protection.
- Speed: It is vital that your enterprise network is running at the speed of your business. It should never hinder your company’s work flow, whether it be accessing data within your company’s network or at global access level. The network equipment that you utilize is the engine that runs your entire company’s network infrastructure.
- Scalability: It is very important that your network be scalable with your company’s growth and downsizing. A network that is not scalable can incur unnecessary cost for your company and unwanted hardship on enterprise efficiency. Scalability means a network infrastructure that offers open source flexibility- the ability for your company to not be locked-in to one specific solution, but instead posses the capability to utilize the best market technology available.
- Savings: Maintaining a network infrastructure can often be a very costly process, and can tip a company’s earnings in one direction or the other. Finding network hardware that is both cheap and reliable is quite the difficult task. Depending on where you look, buying a used cisco router or refurbished cisco switch can sometimes mean the difference in simplicity, security, speed AND scalability. However, it is equally as important that you don’t break the bank building up your company’s network infrastructure. The key is to find a reliable network hardware vendor- whether it be a used network hardware reseller or a direct seller, make sure that they are clear-cut and trustworthy.
Beyond this list, there are basic consumer guidelines that you should follow when purchasing network hardware. One of these components is a vendor’s warranty- make sure they clearly state that they offer a warranty on your network hardware purchase so that if your requirements change, you don’t end up paying the cost.
