The requirements for a 10Base2 network:
RG58u Coaxial cable
T-connectors
BNC's
Terminators
Ground, usually a ground chain
Internetworking with Cisco and Microsoft Technologies pg. 226 and 227
How do X - 25 gateways link hosts and LANs?
Remote LANs can communicate with host mainframes using X.25 gateway. For that a Gateway PC with an adapter Card functions as a cluster conroller and runs special gateway software that contains QLLC protocol.
What is line of sight communication?
Line of sight communication is in the VHF and higher frequencies of the RF spectrum where the wavelength is to short to pass over structures and hills, the transmitter and receiver antennas must be in line of site
Wireless Fidelity.
Edit:
Wrong.
Wi-Fi doesn't mean anything. It was simply a clever name made to brand a product.
Some people simply added the idea of "Wireless Fidelity" during the developmental stages because they couldn't comprehend such a acronym-like name without a literal meaning.
That tagged phrase "Wireless Fidelity" was dropped soon after.
What is the gateway to 192.168.1.254?
If the host is on the 192.168.1.0 network, than the default gateway will often be 192.168.1.1.
However, there are no rules which dictate the IP address of the gateway within a given network; the clients know of the gateway's address either by static assignment or through the DHCP server's records.
How do you open your UDP ports 123456 and 50001 on your router or firewall?
Port 123456 does not exist. To open port 50001 you need to change settings for your port routing tables. Without knowing the exact model of your router it's virtually impossible to help you.
Do you need to set your route up with wep?
It is not necessary to protect your wireless signal with an encrytion key, such as WEP, WPA, etc., but keep in mind that if you don't, anyone can access your wireless internet. Unauthorized accessers can slow down the connection and hack whatever else is connected, such as computers, for sensitive information, such as credit card numbers.
The Nintendo DS supports WEP and WPA security ONLY. All other consoles that use wireless support more advanced encryption, such as WPA-PSK.
Can you turn off wireless routor without going close to it?
Some routers allow remote shut down. So the answer is yes, in some case you can.
What is the best Linux distro for wireless?
SUSE and Red Hat are the two most common. I just loaded SUSE 9.3 on my wireless laptop and it's solid. I'm not too fond of getting "the latest and greatest" since there are often problems associated. I had tried SUSE 10.3 and had a lot of problems so I found an older version. It worked great.
I don't know much about Red Hat except that it's also very popular so it must have something going for it.
What situation would it be most desirable to use a connectionless transport layer protocol?
It is desirable in some cases where the time to establish and maintain a connection is either unnecessary or incurs excessive overhead.
Take, for instance, beacons broadcast by either your cellular towers or WiFi access points--these transmissions are multicast and are not intended for a particular recipient, thus there is no reason to set up a connection to any client devices. Any multicast transmission would not need to establish a connection.
In other cases, such as streaming video applications, a connectionless protocol like UDP is used since lost packets are often unusable once they fail to reach the recipient by a given deadline. An application using UDP transport will be able to ignore the lost packets or explicitly request important packets again, whereas a connection-oriented transport layer like TCP would retransmit stale packets and also throttle bandwidth in response to lost packets.
What is the meaning of the initials WEP?
The initials WEP stands for Web Equivalent Privacy. It is a security system for wireless networks that protects any private and confidential information from being hacked by unauthorized users.
How does one prevent themselves from a WEP crack?
A WEP crack refers to an individual gaining access to a locked or secured WEP access point. One can block this in their router settings by securing their internet with a password. One can also change their settings to allow only a range of IP address'. One can also try and block neighbor's IP address.
Where could someone purchase an IR extender?
Ir extenders can be purchased either online or in the stores. To purchase one online, you could go to sites such as Amazon. You can find it in electronic stores such as Best Buy.
What is port forwarding in networking. What is the main purpose of port forwarding in router?
Well Port Forwarding is really only, opening ports and making them special to let a one connection on it. The main purpose for me is for gaming, you need to port forward for a game to run a dedicated server if the game allows, like Quake 3 arena, or GTA's, or Call of Duty's ect.
What might be the cause if you are unable to connect to radio wireless device?
1.security settings preventing connections
2.out of range
3. wireless router turned off
What are some problems with wireless intercom systems?
Although wireless intercom systems do serve the purpose there are some drawbacks. A wireless intercom system can be vulnerable to both radio interference and security issues. With wireless intercom systems conversations can be picked up by scanners, cordless phones or baby monitors that are on the same frequency.
A broadband modem, a Wireless Router and a gigabit ethernet switch.
Hook any wired devices to the gigabit ethernet switch, hook the switch and connect all the wireless devices to the router, then hook the router to the modem.
You will need to find a Broadband company for your internet, Cable TV company for cable internet or a Phone company for a DSL connection.
You will need a Wireless Router (most also combine 3 or 4 ethernet ports) and possibly an 8 or 16 port GigabitEthernet Switch if you have more then a few wired devices. You have to know the fastest speed the computers and devices are capable of to get the most speed you can. At least have the router an "N" rated speed so when the computers get updated any slower rated ones will have the updated higher N speed cards. Your network will slow down to the slower device speed every time it connects to the network then go to the fastest speed of the next device that connects.
Simultaneous dual band router would be the best, it would keep the slower devices on one band and the faster devices on the other so they don't slow down the network.
Printers only access the network for a few seconds at a time so the speed isn't as big problem for them.
it is a certain code which you can find at the back of your wi-fi broadband home hub. It should say.
Hope this helps :)
