Connecting Two Xbox Consoles:

For this Game LAN party you will need two TV sets, two Xbox, an Xbox System Link cable, and multiplayer games.

Connect each Xbox console to a TV set and use the Xbox System Link Cable to connect together the two consoles (use the Ethernet Ports of the console). Then, follow the multiplayer instructions of your game to start playing.

Connecting Three Xbox Consoles:

In this setup you will need an Ethernet Hub or Switch (preferably use Switch). You will not need the System Link cable in this scenario, but you still need to use normal straight through Ethernet Cables. Connect each Xbox console with Ethernet Cable to the Switch. Follow the multiplayer instructions of your game to start your Home LAN Game party.

Autonet Mobile will be the Internet provider in the U.S., which already offers services to businesses dealing with car rentals. According to statistics from Autonet Mobile, the increase in demand for connecting to the Internet in cars is mainly due to the children, who are already “addicted” with Internet Connectivity and with the use of interactive services. Also, Car Internet Access will be helpful in using various additional functions of navigation systems, for example, to improve the route selection according to traffic jam information received from the Internet.

Uconnect Web will ensure data transmission bandwidth in the range of 400 - 800 Kbit / sec, and the radius of the Wi-Fi coverage will be 30 meters. To ensure the security of wireless connections, the use of WEP encryption and other protocols is recommended. Note also that the system can be modified to work with any mobile network or WiMAX.

The “Net” provides seamless flow of information even if some of its nodes cease to operate. In a “Net” topology, there are alternative routes through which data can pass to reach the recipient. This is the logic that was decided to be implement in 1972 by the working groups addressing the issue, known as InterNetworking Working Groups. The next crucial step was to develop a protocol that would be «smart» enough to understand what routes should be followed in a communication between sender and recipient. The truth is that it took several years to develop the TCP / IP. In August 1983, the Internet - known as Arpanet - consisted of 562 registered computers that could exchange electronic mail between them.

The early years of the Internet did not have anything to do with the current form, regarding the offered services and the way it operates. The Internet user of that era had to type pages of commands on a terminal in order to execute a basic task that is currently done in a few seconds. Things changed dramatically in 1989 when a group of the European Organization for Nuclear Research (CERN) in Switzerland, decided to experiment with the creation of a protocol which would support the transfer of graphics and text (or otherwise hyper-text), using the infrastructure of the Internet. In cooperation with the NCSA, the National Center for Supercomputing Applications at the University of Illinois, they created the first browser. The beginning of the’90s finally finds the Internet to possess its own transfer protocol, the www, which everyone could use with exceptional ease. Here begins the revolution of the Internet.

One determining factor which will always govern the evolution of the Internet is the connection speed of users. During the first few years of the Internet, the telephone network could barely support a decent connection. But the applications that run on the network were not as «loaded» as today. With the passage of time, speeds grew also. The 128Kbits/sec ISDN was the successor to the classic 56kbits/sec modem. ADSL is currently taking off with speeds up to 24Mbits or higher. What does this mean? The speeds are growing. If in the old days the best we could watch on the Internet was a short video of the exotic Bermuda, today we can see the same video in higher quality and with more duration. It is far from unlikely that in the near future all the information coming in our home will be through the Internet. Internet TV with the choice of thousands of channels, or Internet radio stations that broadcast only on the Internet from a remote village in the world will no longer be in the realm of fantasy. What will determine the future Internet development is the connection speed, which as it grows faster, the offered services will expand and replace old methods and habits.

Cisco offers three levels of Career Certifications, starting with lowest to highest:

• Associate
• Professional
• Expert

To start your certification path, you need to earn the Associate level first. There are currently 6 Associate level certification areas, as shown below:

The standard Ethernet network cable used today is the Cat5 or Cat5E (Enhanced) which is a twisted pair cable containing four pairs of copper wires. Some installations also use Cat6 type which is the newer version supporting higher data rates. The connector used for ethernet cables is the 8-pin RJ45 connector plug, as shown in the figure below.

All Ethernet cables support communication over distances of 100m. The older Cat5 cable uses only two pairs to support 100Mbps (Fast Ethernet). The enhanced version Cat5E uses all four wire pairs to support data rates of 1000Mbps (Gigabit Ethernet). Cat6 types support 10Gbps (ten Gigabit) data rates.

Straight Through Vs Crossover Cable

Normally you will need a straight through cable to connect your PC, server, network printer etc. Whatever is connected to a Network switch uses straight through cable. However, whenever you connect two “similar” devices together ( e.g PC with PC, switch with switch, router with router) you need a crossover cable. This looks the same as the straight cable, but the internal wires are connected differently on the RJ45 connector.

Below is a list of the top 5 free firewall software that you can download and install for your PC protection.

Checkpoint, one of the leaders in Enterprise Firewalls, got into the end-user market by acquiring Zone Alarm. The Free Basic Firewall version of Zone Alarm is a good choice but with somewhat limited capabilities compared with their commercial firewall versions. It provides inbound/outbound protection and stealth mode operation.

The NETGEAR XE103 85 Mbps Powerline Network Adapter provides such a solution. This is an excellent product for extending your home network by using standard electrical outlets. The diagram below shows you a simple home network setup using the Netgear XE103.

One possible scenario as shown on the diagram above is to extend your Internet access from your office room to your living room. You just need to plug in two XE103 adapters one in each room (on the electrical outlets) and then use the office room adapter’s 10/100 Ethernet port to connect to your Internet router, and the other adapter to connect any Ethernet-ready device (laptop, PC, XBOX, PS3, DVR etc). If you connect also a third powerline adapter on a different room, then it will participate in the same network segment as the rest of your devices and you will be able to connect another device in your home network.

There is no software to install and works with all Windows versions, or any Game Console types (Xbox,PS3, Wii etc).

The cheapest price I found for this product is from Amazon:

I have the following ClassB network 172.31.0.0/16 that I’m trying to create an access list for. I’d like to allow 172.31.240.0/24 but deny all else, so I’m looking the best way to accomplish this with 2 acl lines.

Answer:

The best way to accomplish the above is to explicitly allow the subnet you want and then deny the whole Class B network as following:

access-list 110 permit ip 172.31.240.0 0.0.0.255
access-list 110 deny ip 172.31.0.0 0.0.255.255

Another option with just one ACL entry would be to permit only the subnet 172.31.240.0/24 and thats it. No other ACL entries are needed since there is an implicit deny at the end of the access list statement.
