Local Area Network

The first 6 digits is the OUI(Organizationally Unique Identifiers given by vendors and then the last 6 digits are used to represent the NIC uniquely with the OUI value.

Local Area Network Cable usually associate with a bus topology network. In a Bus topology network simple LAN cables are used with LAN Hubs ( i.e. having a collection of LAN ports ) which in turn connect many systems with the server systems. LAN cables are available in various length ranging from 1meter onwards.

A broadcast domain is created any time you connect several clients together via a network connectivity device, such as a hub or switch or bridge. They would all be in the same broadcast domain for every client connected to them.

Since a router does not forward broadcast messages, it creates different broadcast domains.

It's valid and it's called a noncontiguous subnet mask since the 16 bits for

the subnet mask are not contiguous. The RFC's, however, recommend against

using noncontiguous subnet masks.

Topology: physical ring of trees, logical ring

You could hard wire the two together but it's easier to go wireless. each computer must be capable of wireless reception, if they are not go buy one or two usb adapters for hooking up to the computer. They come with software that takes you step by step to install the software so no worries there. Also buy a wireless router, linksys, dlink, belkin, netgear etc., plug ethernet line from cable modem into router instead of computer. You can install the software (sometime they want you to install it first before hooking up the router but you can just go to 192.168.0.1 or 192.168.1.1 in your web browser and go from there. Just remember you would probably want to enable encryption, 64 bit is fine. Enter a SSID unique to your desires 9Just name it something you like) and the generate the keys there'll be for rows of key number and letters remember the first row because you'll need it to log on next time you want to join you new network. There is a checkbox so that the key will be remembered so that you won't have to re-enter it every time you join your network. It'll do it automatically but no one outside of your two computer will get in. Tada!

You need: ethernet card cable cat5 4 port hub

Put the ethernet card in the computer. Then connect the cables from both computers to the hub and then from the cable modem to the hub. That should do it.

if you both want to be able to use the internet access, then the easiest way is purchase a network card(ethernet), some CAT5 cable(as previously mentioned), and a router(linksys, d-link, etc). first install the network card in the machine without one. then connect the cable modem to the routers WAN port, it should be labeled that. then in ports 2 and 3, use the CAT5 cable to connect to the yours and your partners computers. after that follow the instructions in the routers manual on final configurations(should be mostly automatic), and you're done.

While wireless is a great, inexpensive, and easy way to network, its speed and throughput is limited (56kbps-108kbps on average for 'turbo mode' links). So you could use the 1 gigabit ethernet copper wire solution (1000kbps) and get more potential speed, but if you have enterprise grade servers on a business campus say, buildings apart, that need more speed and throughput than 1Gb ethernet can provide, you can connect your servers using 10GbE fiberoptic links, using 10GbE fiber PCIe cards. The IEEE standard for 1000base-LX (long range) fiber is about 5km distance, and the 1000base-SX (short range) fiber can reach around 550m distance using the larger diameter 50 micron fiber. Keep in mind that most people's average computer uses a PCI bus for add-in cards, and the regular 32-bit PCI bus is not even fast enough to keep up with true 1Gb speeds, so that is why they only make the 10GbE cards to fit computers with PCIe buses on the motherboards. The rest of the computer needs to be pretty beefy too, in order to even be able to run even near the speeds that the network card is capable of.

Class B

Class A are octets beginning in numbers 1-126

Class B are octets beginning in numbers 128-191

Class C are octets beginning in numbers 192-223

As for most things, the lowest cost version of something is also the simplest version of something. In this case, that would be the bus network topology.

fast packet switching: A packet switching technique that increases the throughput by eliminating overhead. Note 1: Overhead reduction is accomplished by allocating flow control and error correction functions to either the user applications or the network nodes that interface with the user. Note 2: Cell relay and frame relay are two implementations of fast packet switching.

Denial of service is preventing a system from providing resources or services to intended authorized clients.

Advantage of TCP: reliable data transport. Lost packets are re-sent. For this reason, many protocols that transfer data rely on TCP; this includes FTP, HTTP, and several e-mail protocols.

Disadvantage of TCP: The extra overhead makes the transmission slower. When transmission speed is more important than reliability, UDP is used instead. This is the case with phone and video transmissions over the Internet.

Network Topology refers to the way that cables and other pieces of hardware connect to one another. There are four common "base" types of topologies: bus, ring, star, and mesh. There are other types as well, but these are referred to as "hybrid topologies." The most commonly used network topology is a hybrid topology called the Star Bus Topology.

smtp, http, anything on that specific OSI layer.

Bus topology as many nodes are connected to single link

P2P (peer-to-peer) networks are more often used in the home because they cost less than clitn/server network and are easier to configure and maintain.

in other words STRIAGHT THROUGH

yes you can use it this way.

For more efficient usage of IP addresses.

Instead of an ISP assigning a customer an entire class C of IPs (255 addresses), they can assign them a smaller subnet of 8 or 16 addresses instead, only as many as the customer needs.

Generally traffic exiting a LAN is controlled at the router or firewall by setting rules in the configuration files for the router or firewall restricting what IP addresses traffic can be sent to, what devices outbound traffic can be sent from. You can also set rules controlling what outbound ports, protocols, and services will be blocked or allowed. Generally the best way to configure is "deny all and allow by exception" where all traffic is blocked by default and then rules are inserted to allow exceptions for specific traffic. You would also insert settings into the Access Control List.

Shielding is not available for UTP cable; it would be for STP cable.

Both cable types use twists in the wire pairs. The twists help to eliminate crosstalk, which happens when a signal from one wire "bleeds" into another wire, causing interference.

URL and IP address are not the same thing, iP is Internet Protocol, a protocol used for communicating data across a packet-switched internetwork using the Internet Protocol Suite, also referred to as TCP/IP.

Uniform Resource Locator (URL) is a Uniform Resource Identifier (URI) that specifies where an identified resource is available and the mechanism for retrieving it. In popular usage and in many technical documents and verbal discussions it is often incorrectly used as a synonym for URI,

The best-known example of a URL is the "address" of a web page on the World Wide Web, e.g. http://www.harddiskdriverepair.com. and its ip is 216.65.21.62, on this ip there may be have many different domain[url].

IP Address

To set up a good wireless router access point, you will need internet service. Once you plug your internet cable into the appropriate spot on the router and install the software, you should be able to quickly follow the directions on the screen to setting up your home's wireless network.

The subnet depends on the IP addresses of the computers you are trying to connect. In most instances, a subnet of 255.255.255.0 is sufficient enough to get the job done. Subnets only really need to be configured if you are trying to connect multiple network IP distribtuions.
