Computer Networking

Under normal circumstances: No.

The MAC address is hardcoded in the network controller (NIC), e.g. on a Flash chip. If the computer uses a non virtual NIC (as used on virtual machines) and there are no drivers installed that change the MAC inside the operating system, the MAC stays the same.

But drivers/configurations can overcome the static MAC using the OS behavior. In most cases the MAC isn't read by the OS every time it is used, its rather stored somewhere. If that "somewhere" was changed, the MAC will certainly change if the computer is formated. Same applies if the computer uses virtual NICs.

If you know the MAC and it is not the same as hardcoded in the NIC, you can restore the MAC after reinstallation.

Yes! You can install a wireless doorbell with an ordinary wireless network router. This is a very common practice and the company who sold you the wireless doorbell should be able to help you set it up.

I was in charge of more than 500 pcs and at least 20 servers which were organized in couple domains, with advertising systems working 24/7, and video detecting system for security as well as scanning equipment of broad application.

a way or means to connect to the network & access network resources....

no

A server farm is a group of computers connected together. There can by thousands of them in single farm. They are used to accomplish tasks or problems which can not be processed by a single personal computer.

Four. Four pins ie.,TXD,RXD,RTS and CTS. U wil need to use the others in case of devices like modem ,etc.For communication between 2 computers u can avoid thm.

Repeaters are usually used in coaxial based ethernet networks. For this purpose they are used to extend the length of a network segment. For example, in a 10base2 ethernet network the maximum length of a segment is 180 meters. A repeater could join two segments together to increase the length of the network and the number of clients in the network.

In today's modern networks you will see neither coaxial networks nor repeaters in a LAN. Repeaters are used for DSL transmissions, but not for LANS.

This could mean the drivers for your network adapter have been disabled or damaged and are unusable, try grabbing the motherboard driver/utility disc that came with the computer and installing LAN/Network drivers found on that disc.

If you cant find or did not receive a disc try looking on the motherboard manufacturers website for LAN/Network drivers suitable to your motherboard.

You could also try uninstalling Net Protector and seeing if that works, another alternative is contacting Net Protectors tech support and outline your problem to them. They made the program so they could provide better advice.

Link Local Address is used for communication with in a router, if you want to communicate outside your router you need to use site local address.

Easy. Make sure the folder you want to map is shared. Then go into your My Network Places. Find the computer in the list that's sharing the resource you want to map a network drive to. Double-click on it and find the folder to map. Right-click it and and select Map Network Drive. Then configure your options as you see fit, such as the drive letter.

Network protocols provide mechanisms that enables communications between sysytems, clients, servers, websites etc. without protocola systems would not be able to communicate, share data etc.

Star is more appropriate, it's little bit expensive than for instance ring but it's easier to maintain and the bandwidth is higher (depending on UTP you are going to use).

Well, there already is wireless internet. Why computers can't charge wirelessly is a different matter. It is difficult to transport electricity through air, not to mention extremely dangerous and not at all energy efficient. Tesla managed to shoot several thousand volts of electricity over a mile, but there's no (discovered) way to make electricity follow a certain path perfectly through wireless means.

You need to look at the hardware and find out the manufacturer and model number. Most of the large manufacturers will have a Support page, and you'll be able to enter in the model number, allowing you to find the factory manuals, where the login and password will be.

Typically, default logins are either "admin" or "administrator", and the passwords are typically blank, "password", "admin" or "administrator".

Because fibers are not subject to the electromagnetic interference, also speeds are much higher. Fibers can be used to longer distances (up to 40 km).

They will not diagnose problems beyond your organization's entrance facilities.

No, TCP/IP is the not the only protocol used in the world, but it is certainly one of the most popular. Older networks may still use IPX/SPX (Novell) which is a competitor to TCP/IP. Mainframes use SNA or LU6.2 protocols which are very different from TCP/IP. Appletalk is also a competitor to TCP/IP.

If the destination is 192.168.12.135. and the subnet mask is 255.255.255.224, the the packet is sent to your mom's house.

I think the main differences between a network printer and a shared printer are:

1. A shared printer is suitable for small environment

A network printer used for large network

2. shared printer connected system not shutdown

printer did not connect to the system it will connected to switch

3. A network printer has more security

4. A network printer has an IP address

shared printer working only same platform

The index is always in the front of a book, it shows which chapters and what page it is on.
