Local Area Network

For this type of connection you will need to use a *crossover* ethernet cable, not a standard patch cable. This will allow two computers to network with eachother. You can then use the network wizard (if you use windows xp or vista) and choose to create a home network. You will need to assign each computer a unique IP address so they can find eachother, as well as a unique computer name.

Nothing. That is not a valid IP address as its stands however ip addresses with the first 2 octets of 169.254.xxx.xxx means that Automatic Private IP Addressing has been enabled because no DHCP server was found and no static address has been defined.

To find the Network ID and Host ID from an IP address you need to use a Subnet Mask. The address 220.43.6.8 is a class C IP address (Since the range of Class C address is 192.0.0.0 to 223.255.255.255).
The standard default mask for class C is 255.255.255.0


Network address = (IP address) Boolean AND (Subnet mask)
Hence,
network address = 220.43.6.8 AND 255.255.255.0 = 220.43.6
(since 255 means all 1s in binary, hence it'll give the same bits which are ANDed with it, whereas 0 means all 0s in binary, hence it'll give answer as 0 irrespective of what bits are ANDed with it)


Hence Host Address would be the remaining part of IP address = 8

It depends on what kind of model it is, but in the model for computer 321O, it is on the layer between trhe keyboard and the behind screen, and there is a button with the osi code and there says everything.

Coaxcial cable is typically a copper core cable with a shield separated by an air gap. It carries electrical signals along the center conductor relative to ground (usually the outer shield is tied to ground.

Fibre optic cable is glass strands which carrry light in the form of pulses rather than electrical currents.

Fibre carries a digital signal whilst copper (coaxial) commonly carries an analogue signal.

a peer-to-peer (P2P) network

It depends on the type/speed.

For 100 mbit/s twisted-pair (CAT5/6), it's 100 metres, for 1000 mbit/s - 1 gBit/s it's also 100 m *with the correct cable* and no sneaky tight bends/ overdone cable ties.

The older coaxial cables gave 185 m, 500 m, but these are obsolete.

The longest total length for ethernet is 100m, or just a bit over 300 feet. That is for pure cable lengths between any device that would regenerate the signal, such as a switch or hub. The problem is if the signal is to degradded by the time it reaches the device it can't be regenerated properly.

Pros- wireless gives you more room to use the item, and u dont have to worry about the cords getting tangled and so on. Wireless also depending on the item, can run at a faster pace then wired.

Cons- The main bad thing about wireless is keeping track of your receiver. usually with wireless there's some sort of a receiver that connects your wireless item. So if you lose the reciever you r screwed and will have to buy another wireless item. Another problem is with wireless, it usually always runs on battery which means recharging. Recharging can sometimes take a few hours to get to full battery. Or it requires you buying batterys if it is for example AA or a non-rechargeable.

I currently use wireless at home because buying batterys or losing my reciver is never a problem for me. Hope this helped out a bit. need more in depth email me at Burle35@gmail.com

You can use a switch to connect different pieces of equipment. For example, a standard ADSL router only has a port for a single Ethernet cable. If you want to connect 2 or more computers to the Internet, you can use a switch. In this case, the ADSL router and each computer connect to the switch, via a standard Ethernet cable.

If you don't have an Internet connection, you can still set up a home network to share files, etc. To connect only 2 computers, you can connect them directly via a crossover cable. To connect more than 2 computers, better use a switch.

Computer network devices also known as communication devices and they constitute a data communication network. These devices are routers, switches, hubs, LAN cards, gateway, modems, hardware firewall, CSU/DSU, ISDN terminals and transceivers. In an Ethernet or WAN network, the data communication cannot be performed without these devices. Being an IT professional or a network administrator, you must have the good understanding of these devices.

There must be at least 2 computers to form a network. However, a standalone machine that is connected to the Internet (which is itself a vast network of computers) is considered part of that network and is therefore regarded as a subnet even though there's only one machine in that subnet.

If you have physical access to the printer take a look at the printer's configuration menus or have the printer print it out.

You can try pinging the printer by name to see if it responds or if you have access to the print queue configuration information it will be listed there.

Class C

A network card, network adapter, network interface card or NIC is a piece of computer hardware designed to allow computers to communicate over a computer network. It is an OSI model layer 2 item because it has a MAC address. Every network card has a unique 48-bit serial number called a MAC address, which is written to ROM carried on the card. Every computer on a network must have a card with a unique MAC address. The IEEE is responsible for assigning MAC addresses to the vendors of network interface cards. No two cards ever manufactured should share the same address. Whereas network cards used to be expansion cards to plug into a computer bus, most newer computers have a network interface built into the motherboard A separate network card is not required unless multiple interfaces are needed or some other type of network is used. The card implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as ethernet or token ring. This provides a base for a full network protocol stack, allowing communication among small groups of computers on the same LAN and large-scale network communications through routable protocols, such as IP. There are four techniques used for transfer of data, the NIC may use one or more of these techniques. * Polling is where the microprocessor examines the status of the peripheral under program control. * Programmed I/O is where the microprocessor alerts the designated peripheral by applying its address to the system's address bus. * Interrupt-driven I/O is where the peripheral alerts the microprocessor that its ready to transfer data. * DMA is where the intelligent peripheral assumes control of the system bus to access memory directly. This removes load from the CPU but requires a separate processor on the card. A network card typically has a twisted pair, BNC, or AUI socket where the network cable is connected, and a few LEDs to inform the user of whether the network is active, and whether or not there is data being transmitted on it. The Network Cards are typically available in 10/100/1000 Mbit/s. This means they can support a transfer rate of 10 or 100 or 1000 Mbit/s.

Port 69 and UDP are used for tftp transmissions.

Most switches and routers these days allow for a standard straight through cable to connect each other. (So any CAT 5e or 6 cable you find at Best Buy will be fine)

Older devices (Such as a Cisco 2900xl switch) require a cross over cable to connect like devices such as a switch to switch. These cables can also be found at Best Buy and will be clearly labeled "Cross Over".

There are two different standards of straight through cables if making your own. See the related link.

To make a cross over cable, wire one end with the A standard and the other with the B standard.
