Hooking Two Computers Together

Speed Matters: How Ethernet Went From 3 Mbps to 100 Gbps … and Beyond

Although watching TV shows from the 1970s suggests otherwise, the era wasn’t completely devoid of all things resembling modern communication systems. Sure, the 50 Kbps modems that the ARPANET ran on were the size of refrigerators, and the widely used Bell 103 modems only transferred 300 bits per second. But long distance digital communication was common enough, relative to the number of computers deployed. Terminals could also be hooked up to mainframe and minicomputers over relatively short distances with simple serial lines or with more complex multidrop systems.

This was all well known; what was new in the ’70s was the local area network (LAN). But how to connect all these machines?

The point of a LAN is to connect many more than just two systems, so a simple cable back and forth doesn’t get the job done. Connecting several thousands of computers to a LAN can in theory be done using a star, a ring, or a bus topology. A star is obvious enough: every computer is connected to some central point. A bus consists of a single, long cable that computers connect to along its run. With a ring, a cable runs from the first computer to the second, from there to the third and so on until all participating systems are connected, and then the last is connected to the first, completing the ring.

In practice, things aren’t so simple. Token Ring is a LAN technology that uses a ring topology, but you wouldn’t know it by looking at the network cabling, because computers are hooked up to concentrators (similar to today’s Ethernet switches). However, the cable does in fact form a ring, and Token Ring uses a somewhat complex token passing system to determine which computer gets to send a packet at which time. A token circles the ring, and the system in possession of the token gets to transmit. Token Bus uses a physical bus topology, but also uses a token-passing scheme to arbitrate access to the bus. A token network’s complexity makes it vulnerable to a number of failure modes , but such networks do have the advantage that performance is deterministic; it can be calculated precisely in advance, which is important in certain applications.

But in the end it was Ethernet that won the battle for LAN standardization through a combination of standards body politics and a clever, minimalist — and thus cheap to implement — design. It went on to obliterate the competition by seeking out and assimilating higher bitrate protocols and adding their technological distinctiveness to its own. Decades later, it had become ubiquitous.

lan network cables are quite important in the situations they are ...

The lan network cable is a network cablethat cross transmits and receives lines between computers. The cables canconnect hubs along with switches together using standard MDI-X (MediumDependent Interface port, also called an "uplink port"), which arealready lan ports. It is a null modem for Ethernet ports relatively than serialports. It is used to connect similar devices together in a network.Lan networkcables can be used in both home as well as offices networks to connecting twocomputers. An Ethernet lan network cable has its send and receive wirescrossed. The use of hub is very useful if the connection of several computers,and is much faster than a connection to any other cable. However, to connecttogether two terminals there is a technique that avoids the use of a hub.Following are some steps to connect 2 computers with lan network cable Take oneend of the lan network cable and plug up into the network Interface Card portof one computer. Do again the same process with the other end and connecting itinto the other computer system. Make sure that both connections are protected. Lannetwork cable is a variety of the Category 5 Ethernet patch cable. It looksalmost same as ordinary Ethernet patch cable, but it will be labeled somehow sothat you know it's a lan network cable.At this point, make sure that all set upprograms have already loaded. The network ports on both PCs are enabled in PCs.To do this click start then go to the settings, then go on Network and dial upconnections. Be sure that Local area connection marked as Enabled.Enter"192.168.0.2" on the first computer when connecting to the second,and enter "192.168.0.1" on the second computer when connecting withthe first. This will work for any network protocols. After all the procedurerestart the PC, make sure to reboot the other computer system as well.Using a lannetwork cable is a wise decision in any kind of networking situation. The cableallows continuous information to computer simultaneously. This cable is best asa quick fasten for connecting two computers together, However, the specializeduses of lan network cables are quite important in the situations they are required.
