what's the meaning of 16 bit network or 24 bit network ? and what's subnetting ? i need full explanation plz.

That's kind of alot to put in here.\nGot a good reference for ya though...

Ok let's see if you can get it by these examples\n\n1) 192.168.20.0 submask 255.255.255.0 (or 192.168.20.0/24)\n\nthis is a class C IP :\nNetwork IP is :192.168.20.0\nBroadcast IP is:192.168.20.255 \n\nThese two show the start and stop range of the IPs you can use\nin this example you can beging using 192.168.20.1 (not ....20.0)\nup to 192.168.20.254(not ....20.255)\n\nOK?\n\n\n2) 192.168.20.0 submask 255.255.255.128 (or 192.168.20.0/25)\n\nthis is the first part of a class C divided IP \n\nNetwork IP is :192.168.20.0\n. 192.168.20.1\n.\n.\n.\n.\n.\n. (IPs that you can use in this network)\n.\n.\n. 192.168.20.126\nBroadcat IP is :192.168.20.127

Kindly go through Tennanbaum Networking book, they ask most questions from it.\n\nSome of the ques i know are:\n1.7 layers of the network\n2.TCPIP protocol\n3.cables,fibres,etc\n4.encryption and cryptography\nand other topics in the above book

8000 x 8 bits = 64Kb/s \n24 x 64Kb/s = 1536000 - \nremenber that the signalling/timing channel will take up one of the 24 channels\n(in the U.S.A I beleive they call it a T1 circuit - 23 data 1 signalling/timing....here in the U.K. E1 32x64Kb/s thats 30 data, 1 timing, 1 signalling)\n\nas for the data storage sounds like you could look at it like this:\n3 mins ->\n3 x 60 = 180\n180 x 64000 = 11.5Mb for one 3 min message (bits)\ntherefore 11.5Mb /8 = 1.44MB for one 3 min message(Bytes)

Bridge -\nWorks at layer 2 of the OSI model\nForwards frames\nSeparates segments\nUses MAC/hardware addressing\n\nRouter -\nWorks at layer 3 of the OSI model\nForwards packets\nSeparates subnets\nUses IP/network adddressing\n\nFor example:\n\nA router is used to connect two networks together. For example, you have one network at 192.168.1.0 mask 255.255.255.0 and another at 192.168.2.0 mask 255.255.255.0. You need a router between the two to forward packets.\n\nA bridge is often used to reduce broadcast traffic on a network (a switch is very similar to a multi-port bridge). All PCs would be on the network 192.168.1.0 mask 255.255.255.0. The bridge does not look at the IP address, but rather the lower layer MAC address to determine where to send the frame.\n\nThey can both be used to connect WAN links, and for this purpose, bridges are generally less expensive and easier to manage in a small environment. Routers are generally more expensive and easier to manage in a large environment.\n\nI hope this helps a bit - this is a really tough question to answer without first defining a lot of terminology.

[quote]\nCan I collaborate these 2 connections into one, and would that theoretically mean I could double the connection speed to 54Mbps x 2 = 108Mbps?\n[end quote]\n\nNo, i don't think it works that way. What i presume is that only one connection is active at a time since you have no control on what connection a program work. And btw, the speed of one wireless connection is far higher than what you get by your ISP.

A Ethernet hub looks logically identical to an Ethernet bus, and all traffic is visible to all connected interfaces. Therefore, packet collisions are possible, causing serious performance degradation on a busy network.\n\nA switch switches packets to and from connected interfaces by learning the MAC address of each connected host. Therefore, collisions no longer occur between connected hosts which enhances throughput. Also, traffic is not visible between connected hosts; each host sees only traffic "switched" to its interface. Therefore, security is enhanced as well.\n\nA switch is not a router, but modern switches usually recognize VLANs (virtual LANs) allowing several LANs to share a switch.

B is older.  G is newer and is backward compatible with B equipment.  It's faster too and has a larger range.  Don't waste your money on older B routers or cards.  Security is not a function of B or G, but of the software/firmware in the equipment.  Every router has WEP security.  Look for the newer and more secure WPA.

The problem you could have (doesn´t men that it WILL happen) is that if you use routers of different brands, instead of buying only Cisco for example, other routers might not accept comunication from certain subnets.

Generaly, becouse bit numbers are on a boundy of an exponet of 2, we can calculate like this:\n\n1024 bits in 1 kilobit\n1024 kilobits in a megabit\nthus: 1024 * 1024 = 1,048,576 bits

Since you are asking for a lot of information, I will give you a pointer instead of typing it all in.  This should help you quite a bit.\n\nhttp://en.wikipedia.org/wiki/Network_routers#Types_of_routers\n\nGood luck,\nJeffrey

Here is a really good link to these and all types of computer questions.  I have been a long time member.  It is easy to network if you have Windows XP.  Go to your help section and type in networking.  You should have a network wizard that leads you though.  Otherwise go to this link and ask on the network section of forum.

Minimum would be one.\n\nA Class C, 255.255.255.0 would give you one network with 254 clients.\n\nSubnetting it 1 step further would be 255.255.255.128 which would give you 2 networks of 126 clients.\n\nFigure it out like this... taking the last octet (the .128) in binary... 1|000 0000\n\nLeft of the line represents the networks, to the right are the clients (-1) The line represents the division between the number of networks and the number of hosts.\n\nSo, every subnet further (move line right) would increase the number of networks, but reduce the number of clients.\n\nThe smallest number of subnets, you'd move the line all the way left (off the end).  This would give you 1 subnet of 254 clients. (255 - 1)

IPv4 is the addressing scheme in use today. It is made up of 32 bits, broken into 4 octets. It is commonly written in dotted decimal notation.  You're probably familiar with this...ex: 192.168.1.1. \n\nIPv6 is a more expansive version of IPv4 which will eventually be introduced in order to increase the number of available IP addresses.  This address will be made up of 128 bits. Because the size of this would likely be unmanageable in dotted decimal, it will be represented in hexadecimal format.\n\nMAC Addressing is somewhat different. This is the physical address of a piece of equipment. Unlike the IP addresses that identify a piece of equipment on a network somewhere, the MAC address is assigned to the physical equipment by the manufacturer or vendor, and in most cases, does not change. It is represented in a hexadecimal format.

if your modem connects two different networks-subnets,it is called bridge.for instance,you have two different offices,want to connect two different networks.you must use bridge for it.\nif your modem dedicates ip addresses of your pc,etc,it is called router.Routers use in network to find best path to destination.They were smart device in network.Shortly routers manage-run networks.
