This is all about me!
Computer Stuff! A hub is a small, simple, inexpensive network device that joins multiple computers together. Most hubs manufactured today support the Ethernet standard. Non-Ethernet hubs (Token Ring, for example) also exist, but Ethernet is always used in home networking. Technically speaking, hubs operate as Layer 2 devices in the OSI model. Networking Basics Here are some of the fundamental parts of a network:
• Network - A network is a group of computers connected together in a way that allows information to be exchanged between the computers. • Node - A node is anything that is connected to the network. While a node is typically a computer, it can also be something like a printer or CD-ROM tower. • Segment - A segment is any portion of a network that is separated, by a switch, bridge or router, from other parts of the network. • Backbone - The backbone is the main cabling of a network that all of the segments connect to. Typically, the backbone is capable of carrying more information than the individual segments. For example, each segment may have a transfer rate of 10 Mbps (megabits per second), while the backbone may operate at 100 Mbps. • Topology - Topology is the way that each node is physically connected to the network (more on this in the next section). • Local Area Network (LAN) - A LAN is a network of computers that are in the same general physical location, usually within a building or a campus. If the computers are far apart (such as across town or in different cities), then a Wide Area Network (WAN) is typically used. • Network Interface Card (NIC) - Every computer (and most other devices) is connected to a network through an NIC. In most desktop computers, this is an Ethernet card (normally 10 or 100 Mbps) that is plugged into a slot on the computer's motherboard. • Media Access Control (MAC) address - This is the physical address of any device -- such as the NIC in a computer -- on the network. The MAC address, which is made up of two equal parts, is 6 bytes long. The first 3 bytes identify the company that made the NIC. The second 3 bytes are the serial number of the NIC itself. • Unicast - A unicast is a transmission from one node addressed specifically to another node. • Multicast - In a multicast, a node sends a packet addressed to a special group address. Devices that are interested in this group register to receive packets addressed to the group. An example might be a Cisco router sending out an update to all of the other Cisco routers. • Broadcast - In a broadcast, a node sends out a packet that is intended for transmission to all other nodes on the network. Now imagine what this would be like with a dozen or even a hundred roads intersecting at a single point. The amount of waiting and the potential for a collision increases significantly. But wouldn't it be amazing if you could take an exit ramp from any one of those roads to the road of your choosing? That is exactly what a switch does for network traffic. A switch is like a cloverleaf intersection -- each car can take an exit ramp to get to its destination without having to stop and wait for other traffic to go by. A vital difference between a hub and a switch is that all the nodes connected to a hub share the bandwidth among themselves, while a device connected to a switch port has the full bandwidth all to itself. For example, if 10 nodes are communicating using a hub on a 10-Mbps network, then each node may only get a portion of the 10 Mbps if other nodes on the hub want to communicate as well. But with a switch, each node could possibly communicate at the full 10 Mbps. Think about our road analogy. If all of the traffic is coming to a common intersection, then each car it has to share that intersection with every other car. But a cloverleaf allows all of the traffic to continue at full speed from one road to the next. A hub or a switch will pass along any broadcast packets they receive to all the other segments in the broadcast domain, but a router will not. Think about our four-way intersection again: All of the traffic passed through the intersection no matter where it was going. Now imagine that this intersection is at an international border. To pass through the intersection, you must provide the border guard with the specific address that you are going to. If you don't have a specific destination, then the guard will not let you pass. A router works like this. Without the specific address of another device, it will not let the data packet through. This is a good thing for keeping networks separate from each other, but not so good when you want to talk between different parts of the same network. This is where switches come in.

== A little on Disaster Recovery..... == Disaster recovery is the process of regaining access to the data, hardware and software necessary to resume critical business operations after a natural or human-induced disaster. Of companies that have had a major loss of computerized records, 43% never reopen, 51% close within two years, and only 6% will survive long-term. So as you can see it is a very important issue.
We use disaster recovery because if we didn’t, and there was a natural disaster, a fire, power failure, theft, system or equipment failures, human error, computer viruses, or legal issues, we might lose all of our data, hardware, or software. Then there is Business Continuity which is a progression of disaster recovery, aimed at allowing an organization to continue functioning during a disaster, rather than simply being able to recover after a disaster.Business continuity can save money by saving data, it can save employee’ jobs, and it can ensure your company’s future. There is a difference between Disaster Recover and Business Continuity. The difference is that in Disaster recovery you are recovering after the disaster. It is said that in Business Continuity you can start to recover even when the disaster is happening. Business Continuity focuses on making the risks smaller and less severe.
While there are many different kinds of disaster recovery sites out there, most of them fall within three major categories: hot sites, warm sites, and cold sites.
Hot sites have everything that is needed to go live immediately, should a disaster occur. This includes cooling, network connectivity, servers, hubs, switches, and storage equipment, everything your data center has.
Cold sites are everything hot sites are not. These minimal facilities have the necessary floor space and cooling and electrical equipment necessary to build out a new data center should a catastrophe occur, and that is about it. There is no actual IT equipment kept at a cold site, and no data measures are taken for quick duplication or recovery.
Warm sites have the cooling and electrical capacity, as well as pre-built communications equipment for immediate connectivity. There is usually some backup equipment ready for immediate use, such as servers and storage equipment.
A hot site is obviously superior in terms of recovery time and data security. But these facilities are extremely costly. Cold sites, on the other hand, are cost-effective but risky. Warm sites are the choice that most businesses are gravitating toward these days, as they are a compromise between cost and protection.
Then there is the question of where to located the Disaster Recovery program at. While 10 miles between two sites may be suitable in the event of a tornado or a fire, this distance would be insufficient in areas prone to hurricanes, for example, like the Gulf Coast after Hurricane Katrina. It really just depends on where your business is. It is the companies choice.
== Some on Installing drivers... not just network ones... this works for most! ==
Installing Network Drivers
1. Put in the CD 2. Go to My Computer and click on the CD that says 070615_0851(D:). 3. Once this is opened click on the application that says Network Driver. 4. Click “Continue” 5. Unzip folders by pressing “Ok” 6. It might say, “The files already exist, do you want to overwrite them?” Say Yes to All 7. Once that is done Unzipping, press ok. 8. A page will pop up that will be titled README.HTM, Close this. 9. Another window will pop up, showing 5 folders, you want to click on the ones that say Win 2K, Win NT, Win XP. IMPORTANT!!!!! ---- CLICK ON ONE AT A TIME! 10. When you open one it will have many options, click on the blue colored app, that says Setup. This will install one of the 3 needed network drivers. 11. ATTENTION: You must wait for the Setup to close before you go back and do the other one(s). You may choose anyone to start with, it doesn’t matter the order. 12. Once done with all three folders, restart your computer.
== Some on Active Directory... == The main purpose of Active Directory is to provide central authentication and authorization services for Windows based computers. Active Directory also allows administrators to assign policies, deploy software, and apply critical updates to an entire organization. Active Directory stores information and settings relating to an organization in a central, organized, accessible database. Active Directory networks can vary from a small installation with a few hundred objects, to a large installation with millions of objects.
