Comparing Computer networks to Telephone Networks?
88121
This is packet switched technology versus voice switch technology. QoS is hard to relate to telephone other than Immediate, Flash, Flash Override prioreties. When you pick up a phone the switch has just opened a line to you and will constantly await a signal of your voice or dial tone, with a network switch it just waits for a packet to arrive then it decides what to do with it. So when I dial 111-2222 from a phone the phone switch makes a direct link from me to that phone number 111-2222 and doesn't allow any other circuit to connect(setting a side call waiting that is not quite circuit interuption). When I send a packet with a QoS tag it only preempts a packet of a lower value if it sitting a queue with it. If you can just keep streaming out 1500 byte packets over ethernet why prempt a signal if there is nothing to preempt it with. With VoIP you don't assemble a SIP packet until you sample a time frame of voice and then encode it and then package it to go out over ethernet. With a phone connection the phone switch is constant listening to a bandwidth of voice frequencies 0-4000 hertz. QoS is a great thing but it can be foiled by the fact you may get link saturation. Telephone lines know exactly how much voice frequency they are going to sample. While a switch will get some burst of traffic. QoS may be operating fine with other traffic while just one person is browsing the web and 2 people are talking over VoIP but say those 2 people start browsing as well. Now QoS has to preempt that web traffic it has the ethernet queue but the whole queue may be stalled by a collision or a converstation currently taking place. \n\nBasically\nPacket Switched versus Voice Switch to diffrent to compare briefly.

Telnet is a terminal emulation software that dupes an end system into thinking the remote device is directly connected. This allows access to a command line interface of one type or another. There are many different terminal emulation types that are used by each different telnet server.\n\nFTP is a file transfer protocol that allows for the transfer of ascii or binary files between two devices. FTP actually uses many of the same protocols as telnet.

The fundamental difference between dialup and broadband Internet connections is the manner in which the connection is made from your PC to the Internet. A dialup service connects to the Internet through your phone line. The modem in your PC "calls" an Internet Service Provider (ISP) and connects with a maximum speed of 56,000 bytes per second, better known as a 56K speed connection. Each time your PC dials into the ISP, it is assigned an Internet Protocol (IP) address, which you can think of as an "Internet address." A different, unique IP address is assigned at the beginning of each visit so that the ISP can recognize your PC and make sure you can send and receive email, surf the Internet, and so on; basically, this address lets your ISP know where to send the information you are requesting through your modem. In terms of hackers, in order for someone to gain access to your computer, it would be necessary for them to know your IP to successfully do so. The fact that your IP address constantly changes essentially makes your Internet connection more secure.\n\nIn contrast, when you connect to the Internet via a broadband Internet connection, the process is slightly different. Once your PC is connected to the ISP through a cable or DSL connection, it remains connected until the cable box or DSL line is disconnected or physically unplugged. A DSL connection runs through unused wires in your existing phone line without disruption and can translate data at 5 million bytes per second, or 5Mbps. Broadband services are often referred to as "always on" services because it is not necessary to make a setup call to your ISP each time you wish to access the Internet; this means that once you are assigned an IP address, you keep it until you request it to be changed. We'll learn how to do this in a later newsletter.\n\nConnection speed and price are two important considerations when choosing between dialup and broadband. Dialup connection speeds make it more difficult to view certain types of media, such as video, and it can take much longer to download and open email attachments, play online games, and so on. Although the slower connection speed is a disadvantage for dialup users, there are also a few advantages to using this type of connection, which include lower monthly charges and a higher level of security. The cost difference is obvious when comparing the $20-30 per month subscription fee for dialup and the $50-60 per month subscription fee for most broadband services. In terms of security, because the connection is not "always on" and because you are assigned a different IP address each time, it is slightly more difficult to be attacked over the Internet, although nothing is ever fool proof and risks still do exist

You cannot share one phone line between two computers.  You need to connect the computers together.  If they have RJ45 connectors, then they are ready.  An RJ45 connector looks like the connector that goes to the phone line only a little bigger.\n\nIt is also possible to connect computers directly to each other with USB or serial cables.  Personally, I wouldn't mess with this option.  If you do not have RJ45 connectors, you can install a Network Interface Card for peanuts (see sources).  With a NIC in each computer, you can connect each to a hub or just connect them directly to each other with a cross-over cable.\n\nOnce you have your computers connected to each other, select one to be the "master" and configure it for "Internet Connection Sharing".  Use that machine to dial your internet service provider.\n\nWith DSL and Cable Internet being available for not much more than dial-up, you might want to consider spending the extra.  Two computers sharing a dial-up will be slow.  With a cable modem, you may get 100 mbs compared to 56 kbs with your modem.  That's a speed difference of 100,000,000 : 56,000.

do you mean something more that nodes and edges?  what kind of network?  math?  computer?  what?

The idea of a computer network intended to allow general communication between users of various computers has developed through a large number of stages. The melting pot of developments brought together the network of networks[1] that we know as the Internet. This included both technological developments, as well as the merging together of existing network infrastructure and Telecommunication systems.\n\nThe earliest versions of these ideas appeared in the late 1950s. Practical implementations of the concepts began during the late 1960s and 1970s. By the 1980s, technologies we would now recognise as the basis of the modern Internet began to spread over the globe. In the 1990s the introduction of the World Wide Web saw use become commonplace.\nBefore the Internet\n\nA Lack of Inter-Networking\nPrior to the widespread inter-networking that led to the Internet, most communication networks were limited by their nature to only allow communications between the stations on the network. Some networks would have gateways or bridges between them, but these bridges were often limited or built specifically for a single use. One prevalent computer networking method was based on the central mainframe method, simply allowing its terminals to be connected via long leased lines. This method was used in the 1950s by Project RAND to support researchers such as Herbert Simon, in Pittsburgh, Pennsylvania, when collaborating across the continent with researchers in Santa Monica, California, on automated theorem proving and artificial intelligence.\nIn October 1962, Licklider was appointed head of DARPA information processing office, and started to form an informal group within the United States Department of Defense's DARPA to further computer research. As part of the information processing offices role, three network terminals had been installed. One for System Development Corporation in Santa Monica, one for Project Genie at the University of California, Berkeley and one for the Multics project at the Massachusetts Institute of Technology. Licklider's need for inter-networking would be made evident by the problems this caused.\n\n--You can get more information in the link below.--

Right now broadband is the way to go for speed and file size. It's the fastest. Cable TV are normally the providers of the service. DSL is the fastest telephone line service available, but broadband cable is twice as fast. The guy above me, could have told you with-out all of the extra jibberish.

internet (Lower case i) \nAny time you connect 2 or more networks together, you have an internet - as in inter-national or inter-state. \n\n\nInternet (Upper case I) \nThe vast collection of inter-connected networks that are connected using the TCP/IP protocols and that evolved from the ARPANET of the late 60's and early 70's. \nThe Internet connects tens of thousands of independent networks into a vast global internet and is probably the largest Wide Area Network in the world.\n\nARPANet -- (Advanced Research Projects Agency Network) \nThe precursor to the Internet. Developed in the late 60's and early 70's by the US Department of Defense as an experiment in wide-area-networking to connect together computers that were each running different system so that people at one location could use computing resources from another location.\n\nTCP/IP -- (Transmission Control Protocol/Internet Protocol) \nThis is the suite of protocols that defines the Internet. Originally designed for the UNIX operating system, TCP/IP software is now included with every major kind of computer operating system. To be truly on the Internet, your computer must have TCP/IP software.\n\nUnix \nA computer operating system (the basic software running on a computer, underneath things like word processors and spreadsheets). Unix is designed to be used by many people at the same time (it is multi-user) and has TCP/IP built-in. It is the most common operating system for servers on the Internet. \nApple computers' Macintosh operating system, as of version 10 ("Mac OS X"), is based on Unix.

If you don't use dial-up...why do you want computer caller ID??!  With DSL/Cable you can use the phone and computer at the same time.  Move the phone to your computer desk
