Computer Networking

You have to have a router capable of supporting WPA2 as well as a wireless adapter in your computer should support it too. If you are sure that you satisfy both, you need to log in your router, and in settings for wireless network security choose WPA2.

The main benefit of cable sleeving is the protection that the sleeving provides the cables. Sleeves may be made of, for example, nylon, fiber and stanless steel. A company that sells cable sleeving is Cable Ties and More.

This 20-bit field provides a special service for real-time applications. It can be used to inform routers and switches to maintain the same path for the packet flow so that packets are not reordered.

Every router and access point have a way to reset it without software. Most routers have a small push button that you can press with a paper clip. It is router specific. It means that you will have to find manual for your access point to get specific instructions. Belkin website will have everything you need.

Try disabling your proxy server. Most of the time, you don't NEED a proxy server.If you do need one, you may need to consult with your ISP, about the specific setting you need for your proxy server.

A Passive Hub is just a connector. It connects the wires coming from different hubs. An active hub acts as a multiport repeater. Passive hub will not regenerate the signal but active hub will regenerate the signal ....... so active hub is better.

No network is completely unprotected from hackers. Anyone can hack anything with the proper know-how and expertise, just look at the guy who's standing trial for hacking into Pentagon computers and shutting several of their networks for a week! What you need to do is secure your network. The following are three methods for doing so: To keep your network private, you can use one of the following methods: Wired Equivalency Privacy (WEP) uses 64-bit or 128-bit encryption. 128-bit encryption is the more secure option. Anyone who wants to use a WEP-enabled network has to know the WEP key, which is usually a numerical password. WiFi Protected Access (WPA) is a step up from WEP and is now part of the 802.11i wireless network security protocol. It uses temporal key integrity protocol encryption. As with WEP, WPA security involves signing on with a password. Most public hotspots are either open or use WPA or 128-bit WEP technology. Media Access Control (MAC) address filtering is a little different from WEP or WPA. It doesn't use a password to authenticate users - it uses a computer's physical hardware. Each computer has its own unique MAC address. MAC address filtering allows only machines with specific MAC addresses to access the network. You must specify which addresses are allowed when you set up your router. This method is very secure, but if you buy a new computer or if visitors to your home want to use your network, you'll need to add the new machines' MAC addresses to the list of approved addresses.

It's pretty simple. When you encrypt your data with any software (say for example, Data Protecto) you will automatically get your encryption keys. The p[assword of which will be known only by you.

The network card's serial number, usually known as the MAC address.

Layer 4 : Application Layer

Application layer defines TCP/IP application protocols and how host programs interface with transport layer services to use the network.

Protocols: HTTP,TELNET,FTP,SMTP,SNMP,TFTP,DNS etc.

Layer 3: Transport Layer

The purpose of Transport layer is to permit devices on the source and destination hosts to carry on a conversation. Transport layer defines the level of service and status of the connection used when transporting data.

Protocols: TCP and UDP

Layer 2: Internet Layer

Internet layer pack data into data packets known as IP datagrams, which contain source and destination address (logical address or IP address) information that is used to forward the datagrams between hosts and across networks. The Internet layer is also responsible for routing of IP datagrams.

Protocols: IP,ICMP,ARP,RARP,IGMP etc.

Layer 1: Network Access Layer

Network Access layer defines details of how data is physically sent through the network, including how bits are electrically or optically signaled by hardware devices that interface directly with a network medium, such as coaxial cable, optical fiber, or twisted pair copper wire.

Protocols: Ethernet,Token Ring, FDDI, X.25, Frame Relay etc.

An A record is typically the IP address of the hosting account, it directs the domain to the files on the hosting account.

Ethernet is a data link layer protocol - layer 2

A maximum of three co-located direct sequence system are possible because channels 1, 6, and 11 are the only theoretically nonoverlapping channels.

Most twisted pair cable is limited to 100 meters, or 330 feet, before you need to add a repeater.

The computer integration model was designed to ultimately lead to the dismantling of vertical and horizontal barriers while supervisory control concentrated increasingly on work methods rather than on final products (Child, 1987).

Think of it in the terms of the difference between a telephone and a walkie-talkies. With a phone, both people can talk and listen simultaneously, while with a walkie-talkies, they have to take turns talking and then listening.

If the printer can connect to the wireless access point via ethernet and that the printer has been enabled to be used on a wireless network then in theory yes.

Yes, that is the reason network administrators use automatic addressing.
