The functions of the physical layer of the OSI model include data encoding, and transmission of the unstructured raw bit stream. It also includes description of the optical, mechanical, and electrical interfaces to the physical medium.

The difference between baseband coaxial and broadband coaxial cable is baseband coaxial technology uses digital signaling in which the cable carries only one type of digital signal. Where as the broadband coaxial technology typically transmits analog signals and is capable of transmitting multiple frequencies of data simultaneously.

Hit BIG RED SHINY BUTTON. If you don't have a BIG RED SHINY BUTTON, hit the button in front of the comptuer.

Switch
Description: Network Switch a device that seperates the Broadcast domain of a LAN segment from other segments.

You can do a reverse IP search which will tell you where an IP address is located. This may give you a city but won't give you a street address.

You can go to the IP tracing websites such as ip2location.com online demo to trace the Country, Region, City, Latitude, Longitude, ZIPCode, Timezone, ISP, Domain, Netspeed, Areacode and Weather of your IP address. Here is the example of the geolocation traced info for the Google's IP address: http://www.ip2location.com/64.233.167.104

You want to get yourself a copy of Linux STD. That has all the hacking tools you need. Just go on to the official Linux STD site and download it. Its free too.

It belongs to the class A.

If you have a yellow triangle that means there is something wrong with your motem. I reccomend just restarting it. If that doesn't work it may be whoever you are buying the internet from (AT&T, Comcast, ect.)

If you are locked out of the router you will need to reset it. There will be a small button (usually at the back) with reset written beside it. You will probably need a paper clip or something to push it.

Next to the power supply connection is a pinhole Reset button. Disconnect all cords from your router except the power cord. Press Reset button with a pin for 10 seconds. Wait 10 more seconds then unplug router. If it is then reset to the original factory settings you will have to reinstall it using software that came with router. You may have to reinstall your network card software as well.

Some, but not all, routers have a reset button. Different routers require different steps to perform resetting. On many of them, to restore your own "personal setup" that was created when you first installed the router - not the original factory settings - you just have to disconnect the power supply and reconnect it after a minute or two. You will need to locate and read the manual if you cannot get to Belkin's support site online.

Ethernet II

A and B. A is terminated in RJ45 as follows. White/green, green, white orange, blue, white/blue, orange, white/brown, brown... B is white/orange, orange, white/green, blue, white/blue, green, white/brown, brown... Pretty sure B is the most common.

Routers have to be configured because computers are by definition "stupid". What I mean by this is that computers do only what people program or tell them what to do. A router is programmed to communicate and transfer data between computers. If you don't tell or configure the router what devices to communicate with, it will draw a big question mark and do nothing. Routers have come a long way in the past several years, making it fairly easy to set them up, and most companies (like linksys) will help you set up your router if you are unsure of how to do so. Even so, they still have to be configured so they can do what they are designed to do, ROUTE!

The Advanced Research Projects Agency Network (ARPANET) developed by ARPA of the U.S. Department of Defense was the world's first operational packet switching network, and the progenitor of the global Internet.

In the spring of 1967 at the University of Michigan, ARPA held its yearly meeting of the "principle investigators" from each of its university and other contractors. Results from the previous year's research was summarized and future research was discussed, either introduced by ARPA or the various researchers present at the meetings. Networking was one of the topics brought up at this meeting.

The Completion Report continues the story:

"At the meeting it was agreed that work could begin on the conventions to be used for exchanging messages between any pair of computers in the proposed network, and also on consideration of the kinds of communications lines and data sets to be used. In particular, it was decided that the inter-host communication 'protocol' would include conventions for character and block transmission, error checking and retransmission, and computer and user identification.

The initial ARPANET consisted of four IMPs (Interface Message Processors). They were installed at:

UCLA, where Leonard Kleinrock had established a Network Measurement Center (with an SDS Sigma 7 being the first computer attached to it). The Stanford Research Institute's Augmentation Research Center, where Douglas Engelbart had created the ground-breaking NLS system, a very important early hypertext system (with the SDS 940 that ran NLS, named 'Genie', being the first host attached). The UCSB (with the Culler-Fried Interactive Mathematics Centre's IBM 360/75, running OS/MVT being the machine attached). The University of Utah's Graphics Department, where Ivan Sutherland had moved (for a DEC PDP-10 running TENEX).

The first ARPANET link was established on November 21, 1969, between the IMP (Interface Message Processor) at UCLA and the IMP at SRI. By December 5, 1969, the entire 4-node network was connected

The computer's MAC address must be unique, and the internal IP address must be unique. Either of these being the same as another computer's causes issues which won't let your computer connect.

Its all about finding the printer on the network. Is it attached to a computer on the network? Or is it a network printer? Go to the machine you want to print from / control panel / printers / search for network printer.... and then just locate and add.

Make sure you have enabled printer and sharing on your machines. And watch out for firewalls.

1) Header is fixed (20 bytes). 2) ICMP6, IP 3) Types of address: i) Unicast ii) Multicast iii) Anycast 4) 128-bit address. 5) Address space is 2^128. 6) Format of address : colon hex notation. 7) IPsecurity support is built in.

Each Ethernet frame sent from one computer to another includes the source and the destionation MAC addresses. It is from these addresses that the switch learns what device is connected to the port.

At first, the switch won't know the destination address; in that case, it will broadcast the frame through all of its ports. But soon it learns this information.

It is also possible, in some switches, to add the MAC address through configuration commands.

No, network computers are linked together over a particular network and any computer over the network works a personal computer if an operating system is installed that supports personal computing such as windows and Macintosh.

First step to design a network is to prepare a layout . Then Protocols which are to be applied are decided. A network can be designed on Packet tracer (software) .
