Computer Networking

Neural networks (or connectionist models or backpropagation models/networks) are computer simulations of neurons in the human brain. This can mean a group of neurons of about 100 neurons up to millions of neurons. The models are not complete representations of the neurons found in the human body, but simplified and math-constrained concepts of those.

Neural networks are used to discover more about the inner workings of the human brain and most often in case of memory/learning simulations. A good book to learn about these is Connectionism and the Mind. However some knowledge about the brain is necessary.

No. Telephone cables have a different kind of connector. Networking cables (also known as Ethernet cables) are also a bit wider then telephone cables.

If he was on a corporate LAN, possibly the switch port was shutdown and needs to be activated. In some corporations if a virus is found and the helpdesk is not able to remotely remove the virus it will remove the computer name from the DNS entries and pull it from the domain, and remove the user from active directory, then they would not be able dhcp an IP address. If none of the above apply, and a static address was assigned and entered into the IP properties of the PC, verify that the MAC address of the host matches to what is in the DNS entry. You can do a reverse arp lookup via logging into the core switches, and as always check the nic light on the back of the computer, and the cabling. Try pinging the host Ip from another source, extended ping command in the CMD Prompt.

computer network is the interconnected collection of autonomous computers & they are able to exchange information

TCP and UDP are considered transport protocols (layer 4 of the OSI model). They were developed in conjunction with IP (routing - layer 3). Since they were developed together they were also designed to function together.

Well the above answer is not up to the mark.

Tcp is combined with ip because of following reason:-

TCP in TCP/IP ensures that data is broken into packets and provides surety of end to end transmission .

While IP in TCP/IP uniquely identifies the hosts on the network .

So combining the both protocols ensures that data is transferred completely and among right hosts

Internal addresses are hidden from external networks

A company needs fewer registered IP addresses to access the Internet

Basically, yes. It can also be more specific or more complex than this (such as WWANs and VLANs) but the gist of it is:

A network is a group of communication devices which have intercommunication.

no, its just light being transmitted

The coaxial cable I use has at least four layers, sometimes more. At a minimum it has to have a core, a layer of insulation, the second conductor and a coating of another insulator. Better cables have another layer of insulation around the second conductor, a layer of shielding and then the final outside coating.

Yes, it can. Use internet port as a communication port with the network you want to connect to.

The question does not fully make sense , but as far as I understood - any unix based OS is good for you.

the advantage is that since they document every task that has to be made, the quality of the product should always be the same. also, it is easier to replace their employees since everything is documented, they caN just give the procedures to a newbie instead of spennding big money on a training

Yes. There are a number of ways this can (and in fact does) happen. The most obvious happens in a DHCP request, which is a method by which a computer that does not have an IP address gets an IP address from a DHCP server.

Normally, ipconfig.exe is the executable name for IP Configuration Utility and is part of Microsoft® Windows® Operating System. With its help, you can view and assign IP addresses a local machine smoothly.

have an unique IP address

It depends on load, if you are talking about a big company with many computers. The answer is no. You will have to use wired connection. If you are talking about small companies and home business, the answer is yes.

It's most often counterproductive. An employee should be judged on performance, not on whether they visit facebook. It's better to have an efficient, motivated employee that relaxes or is otherwise unburdened with the freedom to visit websites, instead of an unhappy and inefficient drone that stares at his CRM.

Frame Relay is behind that technology. WAN has a host of connection technology options available.

The EMR is the electronic medical records system that is now mandatory for all medical providers to switch over to in the coming years. It will help coordinate patient records between doctors easily.

ASUS P8Z77-V Lk ATX LGA1155 Z77 DDR3 3PCI-E16 2PCI-E1 3PCI SATA3 SLI DVI HDMI DP USB3.0 Motherboard (for an intel processor)

Gigabyte GA-990XA-UD3 AMD 990X AM3+ ATX DDR3 3PCI-E16 2PCI-E1 2PCI SLI SATA3 USB3.0 Motherboard (for most AMD processors)

PCI and PCI-E are the expansion slots

if you don't like these ones and you go out and look for one on your motherboard now next to your processor look for a label (mine says AM3+) so then you know what kind of slot to look for when you are buying your own. Hope this helps
