Local Area Network

Telegrams are sent in data packets. Bits packet frame segment data mean data packet and they belongs to Data link layer.

Client server basically is used for Communication from one system to another.one client can communicate with more then one server at a time.

Actually, an IDS does not sit on one particular layer. It has to examine packets for protocols, how they are being transported, number of packets transmitted, spoofing information, and application layer information.

In general terms, Intrusion detection system and Intrusion prevention system is a Layer 4 device. It filters for malicious data.

Wireless access point security is not generally handled with a "PIN." Perhaps you're trying to password-protect your wireless network or access point. In the future, you should specify what equipment you are trying to use (manufacturer, model).

There are two passwords that might be associated with your access point: one password to protect the settings on your access point so that someone unauthorized can't go and change your passwords on you, and the second password that allows other wireless users to connect to and use your wireless network.

In both cases, you should follow the directions in the user manual that came with the access point. If you don't have it any more, you can try this general procedure:

1. Connect your computer directly to the wireless access point with an ethernet cable. You should connect your computer to any ports on the access point marked as belonging to the Local Area Network, or LAN. This will not generally work in ports reserved for your Wide Area Network, or WAN.

2. Open a browser on your computer. In many commercial routers, this should give you access to a webpage with all your router settings.

3. From here on out, you're on your own. Each manufacturer has their own way of setting passwords for your wireless network and hopefully this web interface will be self-explanatory.

One final recommendation, if given an option between "WEP" and "WPA" security, you should always choose some form of WPA. WEP security is an old, buggy standard and is easily broken.

Analog data transmissions occurs every time you log onto the internet using your pc, your modem, and your telephone line.

Peer-to-peer

Simple Certificate Enrollment Protocol (SCEP).

The WAN or the WWW commonly known as the Internet. WAN stands for wide area network which could link several business locations together as a unit. The device's that connect different area networks together is called a "Router". With a router, you can connect to the Internet, or to the companies WAN (wide area network).

* SMB is still developing, so maintaining compatibility with Microsoft's implementation is a constant battle * Threat of legal action against commercial users of Samba from Microsoft

Use 'netstat' for this purpose.

The usual term is either a file-server or network server.

Yes, a LAN could have two DHCP servers, but it wouldn't make much sense. Typically each LAN has it's own DHCP server or uses a DHCP relay agent to get an address from another subnet.

• Switching involves moving packets between devices on the same network. *Conversely, routing involves moving packets between different networks.
• Switching is able to determine where a packet should be sent by examining the MAC address within the data link header of the packet (the MAC address is the hardware address of a network adapter).
• A switch maintains a database of MAC addresses and what port they are connected to.(operate at layer 2 of the OSI model).
• Routers, on the other hand, operate at layer 3 of the OSI Model.
• A router is able to determine where to send a packet using the Network ID within the Network layer header. It then uses the routing table to determine the route to the destination host.

Physical layer = Hub, NIC, Repeater.

Data Link Layer = Switch, Bridge.

Network Layer = Router.

It can either be called a Host or a Node. Either one is correct.

There are a few reasons that optical fibers are wrapped with aluminized Mylar. The Mylar acts to reduce signal loss by reflecting lost light back into the fiber, rather than absorbing or refracting it. It also serves to physically reinforce the fiber, even though optical fibers are relatively robust on their own; the wrapping of aluminized Mylar tape serves as a buffer to physical friction, shock, and pressure (as seen during handling and installation), adds some strain relief/protection (as the fibers typically are least resistant to strain), and also adds some measure of environmental protection, to slow degradation of the fiber from environmental contaminants near the ends, where the cable bundles "break out" for connection to endpoints or repeaters.

It is not possible to use WLAN and LAN connections simultaneously for greater Internet speed without the use of a special router or paid software.

Both are same...
