Computer Networking
Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

How to do you create a music or movie server for an internet cafe?
well, you can easily create a music server with a shoutcase or icecast server. It is a type of broadcast program that binds to a port on the server program, and the client programs use mp3 software such as winamp and open that specific location:port and it creates a "live stream"
As for movies, not sure how you can live stream it but if you just throw a movie up on the net, you can make them go to the exacty URL and watch it over the intranet or internet.
Why would a company have two domain names for one IP address?
There are many reasons why a company would have more than one domain name redirected to one I.P. address. For example company XYZWidgets could have XYZWidgets.com, XYZWidgets.us and XYZWidgets.org, and want all those domain names to go to the same website.
What color is live cable in UK?
For 3 phase, L1 is red; L2 is yellow; L3 is green; Neutral is blue; Earth is yellow&green.
For single phase, L is red or brown; Neutral is black or blue; Earth is yellow&green.
NDS server is used to serve the CDT server, which is used for call detailed trace.
How much does The Verizon Hub cost?
it will run you about $200 for the hub and and 35 bucks for the monthly access fee.
How you can connect a computer to another computer by a single networking cable?
You have to have a special cable which is "cross connection cable" or something like that.
Will the PC network speed increase if hub is replaced with switch?
Any speed difference will not be detectable. Check that the hardware is all capable of 100mbps. If most components are capable of 100MBPS but a couple components are only working at 10MBPS, the entire network will run slower. Also, when some components that your computer want to access are turned off the network will noticably slow. For example, if your computer wants access to a printer on another computer, your computer may run noticably slower.
What are the advantages of using logical address?
One might be able to get more appropriate traffic to their website or email address if the words that make it up describe it in some way, or are logical.
Which three main features must Routes have in a routing table?
- the network id: i.e. the destination network id
- cost: i.e. the cost or metric of the path through which the packet is to be sent
- next hop: The next hop, or gateway, is the address of the next station to which the packet is to be sent on the way to its final destination
Why are Ethernet II frames preferred over Ethernet 802.3 frames on contemporay lans?
They can support multiple higher-layer protocols, and Ethernet 802.3 frames cannot.
When the host portion of an IP address is all binary ones?
The host portion of an IP address of all zeros indicates that you are referring to 'this network'. For example, the address 145.5.0.0 means the network 145.5
Is the default gateway address a portion of the destination IP address?
No, it is not. A destination IP address may be any address, usually on a completely different network. The default gateway address is used to determine where to send packets that need to be routed outside of the current local area network.
What is ping 127.0.0.1 checking?
This ping command checks that the TCP/IP stack is installed and working correctly.
Why are NIC cards classified at data link layer?
The Data-Link layer is the place where the data's are broken in to small transferable packets. The NIC card is included into this layer is for one main reason as i have studied. Though the NIC card is a Physical device the algorithms which are embed with in the NIC card do the packet process. The data link layer is the place where the packets are sent to the next layer. though it looks simple the algorithm is not a simple calculation.
i hope this would help u all

What classes do you need to take to become a computer networker?
basics of information systems
basics of computer hardware
principles of networking - Local / Wide Area Networks (LAN/WAN)
What are the necessary issues to be tackled in host management?
Security, various operating systems and storage are all major issues when tackling host management. You have to make sure your equipment is properly prepared to handle what your customers attempt to do on the network.
When segmenting a LAN what device cannot be used to reduce the collision domain?
Hubs do not reduce collision domains. All devices connected to the hub are in a single collision domain, where as on a switch, each port is its own collision domain.
Yes, if you view it from the perspective that the X server is providing the display, rather than the client providing an application.
Software trends in client server computing?
In order to stay abreast of the new trends in Client-Server, we must start by looking at what is happening in the software trends as a whole. In the 1960s and 1970s was the era of centralized computing, with IBM mainframe occupied over 70% of the world's computer business. Throughout the 1980s, many functions once performed by the omnipresent IBM behemoths were systematically taken over by PCs. The result of this gravitational shift toward personal computers makes two significant remarks on the computer industry:
The PC shift made corporations to reset their IT organizations in a number of ways. We are currently in the Client-Server phase of the software development and will eventually move towards the truly distributed computing environment. In IT manager's point of view: distributed computing can be used as a tool for business process reengineering, corporate right-sizing, and customer responsiveness. The new software developments can be characterized as follows:
- Distributed: The main operating force in the software industry is the drive toward distributed computing, currently in its Client-Server phase.
- Multiphased transition: Client-Server is merely an intermediate step toward distribution. The ultimate goal is collaborative computing based on peer-to-peer networks.
- Enabling technologies: Prominent supporting technologies are object-oriented components, document-centric software architectures, data warehouse technology, standards, and the end-user programming trend.
On the other hand all the above software developments cannot afford to become set in its ways and without taking considerations or meeting the business needs as follows:
- Isolated desktop software solutions are no longer sufficient. The software industry must respond to consumer demand for portable, interoperable, distributed software solutions or else becomes extinct like their mainframe-only predecessors.
- Open Systems for Computing: the pressure on software vendors to establish interoperable, distributed, easy-for-end-user-programmers-to-use tools and standards upon which enterprise-wide architectures can be built.
-Business process reengineering increased consumer expectation, and networked distributed hardware, as well as numerous second-order complications are driving software complexity through the roof.
The software industry will, out of necessity, respond to the above pressures by forming forums, consortia, and back-room alliances in order to establish market-leading architectural infrastructure standards, interfaces, and middleware for the express purpose of shifting the balance of power in favour.
Does the data link layer finalize and frame a packet?
yes,data link layer finalize and frame a packet as frame is a series of bits that units a data.........
How do nodes in a 10base5 network attach to the backbone?
To connect a node to the wire, an Auxiliary Unit Interface (AUI) is used from the node to a transceiver. The transceiver is attached directly to the wire.
