Local Area Network

In networking terms a server is a PC that contains information (usually for a business) and can share that information to other computers on the same network. The individual Computers are called Clients.

segmentation

They send the message again, generated by a random time, so the don't collide again.

A crossover cable is used to connect a Hub or Switch to another Hub or Switch - or a PC to another PC.

The host range is 192.168.10.193 - 206; total usable hosts =14.

There can be at least two reasons for icmp (ping) testing. One is for security reasons (watching for ping floods, amplifier attacks) and the other is to test timing between two endpoints.

Star Topology, where Hubs can act as repeaters.

First of all you can use a separate room with limited access, also there are some special safes you can purchase. Safes allow to block physical access to equipment. They are pricey though.

A signal's data rate is often confused with its baud rate rate. The two are closely linked but are not identical.

The data rate is a measure of how many bytes or bits of data can be sent per second. The baud rate, on the other hand is a measure of how many physical bits are sent per second, including start and stop bits and other idle bits. The baud rate is therefore higher than the data bit rate. A typical asynchronous serial signal that runs at a rate of 9600 baud will carry ten bits for every byte of data sent. One bit is a start bit. Another is the stop bit and the remaining eight are the eight bits of data. The bit rate is actually 8/10 x 9600 = 7680 bits per second.

Most transmission methods have an overhead that makes the data rate a little slower than the baud rate. In time critical applications, the difference between them can become significant.

What protocol is used by web servers and on which port ?

Router uses IP address of destination node to do the direct packet switching..while bridge & switch uses the MAC address to packet forwarding.

This is possible in Linux based system's. IP's can be splitted in two IP's ! And it can be achieved from single NIC card !

Sure you can .. if you are using Windows you can configure the TCP/IP Protocol in your Network Properties and then you can add additional IP addresses

'''Windows XP''' * Control Panel -> Network Connections -> Local Area Connection -> Properties -> Internet Protocol (TCP/IP) * Type in a static ip address * Then click Advanced * Under the "Ip address" group box, click add to add more ip addresses.

You would need to do this in the case where you need to connect to more then one different subnet where proper routing has not been set up.

yes, but its only a private address and your providers DHCP set will not allow you to connect to the internet in that fashion. Now if you wanted to connect another computer without the use of a router you could use both NIC cards in you computer by setting up the second as your DHCP and sharing your first NIC card that is connect to the internet.

lan = local area network man = metro area network wan = wide area network

local area network

By using 255.255.240.0 as a subnet mask you have 4+8 bits remaining, that can be used for host IP addresses. So you have 2^12 IPs - 2 IPs = 4094.

This "minus 2" IPs are because first IP is always the IP of entire network and last one is a brodcast address. None of them can be assigned to a particular host.

A communication in between two or more computers is called a network..and the process of making network is called networking..there are three basic Types of networking..1) LAN ..2) MAN...3) WAN....

Session and Presentation Layers

We're used to the idea of information travelling in different ways. When we speak into a landline telephone, a wire cable carries the sounds from our voice into a socket in the wall, where another cable takes it to the local telephone exchange. Cellphones work a different way: they send and receive information using invisible radio waves-a technology called wireless because it uses no cables. Fiber optics works a third way. It sends information coded in a beam of light down a glass or plastic pipe. It was originally developed for endoscopes in the 1950s to help doctors see inside the human body without having to cut it open first. In the 1960s, engineers found a way of using the same technology to transmit telephone calls at the speed of light (186,000 miles or 300,000 km per second).

There are three features that allow TCP to reliably and accurately track the transmission of data from source to destination. They are flow control, session establishment, and numbering and sequencing.

• Files can be stored on a central What_are_the_advantages_of_local_area_network(the file server) allowing data to be shared throughout an organization.
• Files can be backed up more easily when they are all on a central fileserver rather than when they are scattered across a number of independent workstations.
• Networks also allow security to be established, ensuring that the What_are_the_advantages_of_local_area_networkusers may only have access to certain files and applications.
• Software and resources can be centrally managed.
• Network versions of software often allow for their speedy installation on workstations from the What_are_the_advantages_of_local_area_network.
• Expensive devices such as laser printers or scanners can be shared.
• Users can access their files from any workstation

by reducing the hosts

You need a WAP - WIreless Access Point. This is a bridge device that connects the two types of networks together. Or, use a router.

Subnetting is essentially the modification of a single IP network to create two or more logically visible sub-sections. It entails changing the subnet mask of the local network number to produce an even number of smaller network numbers, each with a corresponding range of IP addresses. Subnetting is required when one network number needs to be distributed across multiple LAN segments. This may be the case in instances when: * A company uses two or more types of LAN technology (for example, Ethernet, Token Ring) on their network.

* Two network segments are restricted by distance limitations (for example, remote offices linked via point-to-point circuit).

* Segments need to be localized for network management reasons (accounting segment, sales segment, etc.).

* Hosts which dominate most of the LAN bandwidth need to be isolated.
