Computer Networking

same as dark matter

Essentially IR port on PDAs or a computer is a serial port with physical connection in form of Infrared light instead of electrical wires. These ports have infrared LED transmitter and Infrared photo diode receivers.

You have to have IR built-in to your computer or you have to buy an adapter for it

In order to tell the difference between different data segments the transport layer assigns an identifier to an application. The TCP/IP protocols call this identifier a port number. Each software process that needs to access the network is assigned a port number unique to that host. This port number is used in the transport layer header to indicate to which application that piece of data is associated.

Hope this helps!!!

No, within a bus topology, the client PC's are indepentent of each other. So if PC 1 fails, PC 2 will still be connected to the server. But, PC 2 won't be able to get data/information from PC 1.

Rip V2, EIGRP

Since a router does not forward broadcast messages it automatically splits up the broadcast domains for all clients connected to them.

What do you mean working with each other?

802.11g is the wireless protocol, which you can secure with WAP or WEP encryption and it would be called a secured wireless network. Also, it would be called a WLAN for wireless local area network.

They're the same thing.

Assigned terms may, on the one hand simply substitute terms represented in the document with other terms, e.g. from a controlled vocabulary. On the other hand, an assigned term may represent a conceptualization of the document, which is not expressed in the document with any terms. A romantic poem, for example, does not describe itself as such, but may be assigned the term "romantic poem". It is common to classify documents according to an organization of disciplines. Documents may or may not describe their disciplinary memberships. Even if they do, the authors organization of disciplines may be different from those chosen to be assigned by a library or an information system. Assigning terms, which a not simple substitutions of synonyms, but which represents independent conceptualizations of document contents may turn out to be the most important area in which human indexing is better than automatic indexing.

If you're looking for a router that would support just class b, then that would be very unlikely. However, most modern routers support class b, g, n, and even some experimental ones like from Belkin, where they have N1,and some others.

Hope this helps!

BTW, don't take this advice any less from hearing this, but, you're hearing this from a twelve year old who read the whole certification book for microsoft, built his own computer, is programming his own laptop with Linux/Ubuntu, won the science fair 4 times in a row, and knows every single in and out of networking, audio, video, and a couple of other things...

8O....yes, I know

PEACE OUT WORLD!!!!

well wat u jst said is absolute nonsense b g and n on a router is only a type of range and speed

class b is am ip addressing scheme and any router will support any ip address as long as its a b or c class ip's i built my own computer too lol but u dnt see me putting that in the question anyways back to my coarse work MCDST and networking and if u dnt knw wat MCDST is u etter google it before you sit down lolzzzzzz :D

I have that problem with my lap top as well. It usually means that you have a corrupted windows file, or missing file. When it attempts to load that file to get into windows, it chokes and resets. This can be caused by a virus (though unlikely), but can also happen if you delete files, or if (in my case), for example your computer crashes while installing an upgrade (like service pack 2). You should have a factory restore disk that should take care of the problem (unless you have HP cuz they suck like that), or possible full reinstall disks. Fully reinstalling will cause you to lose all of the things you had on it before, however, but a restore disk will not. Good luck, hope it helps.

Under normal conditions light travels in a straight line. Fiber optics can take the light anywhere you want it to go.

Yes - this is a broadcast address for all subnets in the 11.0.0.0 network.

Connections to a network depend on the topology and cable type you are using. If we take the most common connection it is via UTP (unshielded twisted pair) cabling, utilizing an RJ-45 connector. This connector takes 8 wires in a modular connection on the cable.

Plug one end of the cable into a network interface card on your PC, and the other end to a network connection, which may be a switch, router, hub, etc. The EIA/TIA structured cabling guidelines 568A/B will tell you much more about these types of connections.

Thinnet coax uses a BNC connector, which is a twist-on, twist-off connection used with a T-fitting.

Your network adapter must configured to receive IP address from DHCP server (default in Windows), also your firewall must allow connection to the port 67.

True

i see you also have a computer systems class

RIP v1 is a classfull distance vector protocol.
It send and receive v1 informations only

This is usually done because of the requirements of the data transfer. For example, FTP (file transfer protocol) will use TCP for transport because we want to make sure the data was transferred reliably. DNS will use UDP because we don't need the handshaking or connection based transport.

to check if your Ethernet card r INTERNET is working r not, just type the following in command prompt:

ping 127.0.0.1

This command is basically used for self test of NIC(Network Interface card) card

Multiple-device dialing causes multiple physical links to be combined into one logical link

you can use multiple Dial-up modems to connect to the Internet to increase the total speed of your transfers. so instead of have a single 56k Dial-up line you can have 2 56k lines that act as one for greater bandwidth.

You might use this feature if you do not have access to DSL or cable services.

A router allows for internetwork communication.

You can also use a switch implementing VLANs, STP, and VTP. But this method is rather tedious because you have to configure each used port on each switch.

I would go into a full description, but if I did, I would be here for 3 days.

01. RJ45 is the connector designed for connecting Cat5/Cat6 cables. It is not used for connecting fiber optic cables.

With the advent of the Integrated Service Digital Network (ISDN), the telecommunications network no longer had to separate voice, text, data, and image traffic
