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.

Do all computers on a network must have the same computer name?
No. Each computer has to have a unique name on the network
(example: Desktop-John, Desktop-Matt, Laptop-Kim)
What factors account the success and popularity of TCP IP?
- Integrated Addressing System: TCP/IP includes within it (as part of the Internet Protocol, primarily) a system for identifying and addressing devices on both small and large networks. The addressing system is designed to allow devices to be addressed regardless of the lower-level details of how each constituent network is constructed. Over time, the mechanisms for addressing in TCP/IP have improved, to meet the needs of growing networks, especially the Internet. The addressing system also includes a centralized administration capability for the Internet, to ensure that each device has a unique address.
- Design For Routing: Unlike some network-layer protocols, TCP/IP is specifically designed to facilitate the routing of information over a network of arbitrary complexity. In fact, TCP/IP is conceptually concerned more with the connection of networks, than with the connection of devices. TCP/IP routers enable data to be delivered between devices on different networks by moving it one step at a time from one network to the next. A number of support protocols are also included in TCP/IP to allow routers to exchange critical information and manage the efficient flow of information from one network to another.
- Underlying Network Independence: TCP/IP operates primarily at layers three and above, and includes provisions to allow it to function on almost any lower-layer technology, including LANs, wireless LANs and WANs of various sorts. This flexibility means that one can mix and match a variety of different underlying networks and connect them all using TCP/IP.
- Scalability: One of the most amazing characteristics of TCP/IP is how scalable its protocols have proven to be. Over the decades it has proven its mettle as the Internet has grown from a small network with just a few machines to a huge internetwork with millions of hosts. While some changes have been required periodically to support this growth, these changes have taken place as part of the TCP/IP development process, and the core of TCP/IP is basically the same as it was 25 years ago.
- Open Standards and Development Process: The TCP/IP standards are not proprietary, but open standards freely available to the public. Furthermore, the process used to develop TCP/IP standards is also completely open. TCP/IP standards and protocols are developed and modified using the unique, democratic "RFC" process, with all interested parties invited to participate. This ensures that anyone with an interest in the TCP/IP protocols is given a chance to provide input into their development, and also ensures the world-wide acceptance of the protocol suite.
- Universality: Everyone uses TCP/IP because everyone uses it!
This last point is, perhaps ironically, arguably the most important. Not only is TCP/IP the "underlying language of the Internet", it is also used in most private networks today. Even former "competitors" to TCP/IP such as NetWare now use TCP/IP to carry traffic. The Internet continues to grow, and so do the capabilities and functions of TCP/IP. Preparation for the future continues, with the move to the new IP version 6 protocol in its early stages. It is likely that TCP/IP will remain a big part of internetworking for the foreseeable future.
Yes. Starting with Windows 2000, Windows XP.... and there is also Operating System that had been made that specialized in the internetwork of computers. It is called Windows NT (network/networking).
How do you avoid data buffer overflow in transport layer?
There is a special bit signaling if the buffer is full. If the buffer is full the bit signals "BUSY" as result transmission stops until the bit changes to "READY" and transmission resumes.
What is the collection of hosts connected by networking device?
it is the collection of computer and devises connected togethere, and connected in the sane building or immediate area
ICMP
What is the difference between a host and a workstation?
host or server is same. the server provide the service to the end user or client.
like engineered programming.
What is a multifunction device?
A multifunction device is a single piece of equipment that looks like a copy machine but provides the functionality of a printer, scanner, copy machine, and perhaps a fax machine.
How can one access a Remote Mac?
Once can access a Mac remotely by downloading the Apple Remote Desktop application. The software will allow a user to access a number of Macs that have the same application installed.
Is ip address is a physical address?
No an IP address is considered a logical address. Physical address refers to a MAC address which is burned into ROM on each Ethernet network interface card or NIC.
In theory every NIC card has a unique physical address which denotes its manufacture and its own unique address.
The logical address or IP internet protocol address is used for layer 3 routing between networks and subnets.
What configuration of a router would be restored to the device after the reload?
The System Configuration Dialog of a router would be restored to the device after the reload.
What is the maximum number of users per router?
Routers don't have a fixed maximum number of users. However, something in the router might get saturated, especially if there is a lot of network or Internet traffic. The details vary, depending on the type of router; high-end routers (which may cost half a million dollars or more) might be designed to transport a terabit per second of network traffic, or even more.
Log in as the administrator. and change settings from there
How do you connect a male RJ45 connector to a coaxial jack?
A male RJ45 plug is specifically designed to fit an RJ45 socket.
You would need a device that takes both allows you to plug both coax and an RJ45 connector into it. Perhaps a cable modem?
Kind regards,
Gareth
How can we Shut down client computer from server?
To shut down WindowsXP computers from a Windows2003 Server use the "shutdown" command. The shutdown command can be run as part of a batch script, or interactively with "shutdown -i" A good starting point is http://www.computerperformance.co.uk/w2k3/shutdown.htm
What benefits does of a network administrator configures the switch as an HTTP server in new switch?
This allows web-based configuration tools to be used with the switch.
In some countries there are Security Businesses that will design, install, and maintain / monitor CCTV systems
How many layers of the osi model does the ping command test?
ping checks the physical -> data -> network layers.
It uses ICMP
How do you setup router passwod?
there are 4 types of password used in router
1. previlage password
2. vty
3. console
4 auxilary
on the router
goto globle configuration mode
type:
router(config)#enable password [password] (for normal)
router(config)#enable secret [password] (for encrypt password)
router(config)#exit
router(config)#ctrl+z (to save)
it is used to set password in previlage mode
Which address in a network cannot be assigned to hosts?
The general rule in networking is that the network id cannot be all zeroes or all ones, and the host id cannot be all zeroes or all ones.
The all zero address results in a reserved address meaning "this network".
The all ones address is a broadcast address, and cannot be assigned to a single system.
Which connector would be used in a 10BASE2 Bus topology?
BNC connectors, Ts, barrel, 4ways, and the all important terminator.
What is the function of ping on modems?
Ping is one of the most useful network debugging tools available. It is very helpful also.
What testing types will you perform by running and compiling code?
You should test for bugs or unexpected results and for security holes.
