Computer Networking

All devices on your network segment. NOTE: In dotted decimal notation, which is the most common way of expressing IP addresses to make them easy for humans to read, this would be 255.255.255.255 or what is commonly referred to as all ones.

it's the MAC address

Is a word that has a specific meaning within a specific field of expertise

With regard to the TCP/IP Network Model, the network access Layer is the lowest logical layer in the model and provides specifications for how data (bits) should move over the network.

The OSI (Open Systems Interconnection) model is a conceptual framework that describes how data is transmitted over a network. The OSI model divides the process of network communication into seven distinct layers, each of which performs a specific function. The layers are designed to work together seamlessly, making it easier to develop and troubleshoot network systems.

Using the OSI model can facilitate teaching and learn about networking in a number of ways:

Structured Approach: The OSI model provides a structured approach to understanding how network communication works. By breaking down the process into seven distinct layers, learners can better understand the complexities of network communication and how each layer contributes to the overall process.

Common Language: The OSI model provides a common language that network professionals can use to communicate with one another. This can make troubleshooting and problem-solving more efficient, as all parties involved can use the same terminology and concepts.

Modular Design: The OSI model's modular design makes it easier to develop and maintain network systems. Each layer performs a specific function, and changes made to one layer can be implemented without affecting other layers, allowing for more flexible network design.

Standards-based: The OSI model is based on international standards, making it a widely recognized and accepted framework for network communication. This means that learners who understand the OSI model will have a strong foundation for working with a wide range of network technologies and protocols.

Overall, using the OSI model can facilitate teaching and learning about networking by providing a clear and structured framework for understanding how network communication works, promoting common language and modular design, and being standards-based.

Class A default is 255.0.0.0

Class B default is 255.255.0.0

Class C default is 255.255.255.0

-The geographic scope of the network

-The physical layer implementation

-The number of hosts to be interconnected

c) Authentication: It ensures that
communication from one node to other is
genuine. Only legitimate users can access
the system and services. Two used
systems are 'open system' and 'shared
key'.
(d) Availability: Availability ensures the service
offered by node will be available to its users
when expected, in spite of attacks. Also
only legitimate users can access data
anytime.

TCP initializea the sequence numbers for the sessions.

Telnet operates over TCP Port 23.

Without DNS you would be typing

http://74.125.77.104 instead of www.google.com

http://208.117.236.73 instead of www.youtube.com

DNS was only designed to make life easier for us humans. Also if you paste those ip addresses into your address bar they will take you to the site.

A print server accepts print jobs from many computers and prints them to the printers it has connected to it. The ideal situation would be to have a number of identical printers connected to the server; this way, when you send a job to print it just picks the first free one and starts outputting pages.

If you have:

a big network--hundreds of machines...

or you print huge jobs and don't want to slow down the host workstations doing it...

or you've got a lot of similar printers and don't want your users to be able to pick the one they print to (which sounds like you're being a dictator, but what you're actually doing is load balancing--given a choice 90 percent of all users are going to take the first one, which would mean that in a network with six printers on it one printer would print everything and five would sit there idle almost all the time) ...

then you need a print server.

No, they are not. The reason is that the more users/clients you have on a Peer to Peer network the harder it is to administer it. Everyone is their own administrator and you can't enforce policies, backups, or security easily with a peer to peer network.

A general rule of thumb in the industry is to limit such a network to around 10 devices. Although more could be used it becomes an administrative and troubleshooting nightmare.

There are a total of 126 networks with 16,777,214 addresses per network in a Class A Address of ipv4. Such a big range Ha!

A Translational Bridge is used to connect networks that use different protocols.

What makes a computer so powerful is the fact that they operate with amazing speed, reliability, and accuracy. Computers have nearly unlimited space for data/information. Most computers carry out billions of operations a single second. The world's fastest computer can perform trillions of operations in one second.

Whether or not a network cable is connected to your computer.

An ethernet cable splitter allows one to connect two computers to one cable. First, strip the ooating off the end of the cable wire. Second, untwist the wires inside. Third, connect the wires using an RJ45 connector.

there are two types of addresses: network addresses and physical addresses

First, pick out the address you wish to permanently assign to the workstation, plus the subnet mask you are going to use.

Then, bring up the network adaptor properties and put the address in the dialog box (for Windows).

For Unix/Linux systems, using the ifconfig command allows you to assign a static address (see first part above) to any adaptor.

You have many options. The newest cable standard is DOCSIS 3.0, which supports speeds in excess of 100Mbps by using multiple bonded channels. The Motorola Surfboard line is a proven performer. I haven't personally used any of their combo units, but currently use a Motorola SB6120 DOCSIS 3.0 standalone cable modem.
