a) Repeater – Also called a regenerator, it is an electronic device that operates only at physical layer. It receives the signal in the network before it becomes weak, regenerates the original bit pattern and puts the refreshed copy back in to the link.

b) Bridges – These operate both in the physical and data link layers of LANs of same type. They divide a larger network in to smaller segments. They contain logic that allow them to keep the traffic for each segment separate and thus are repeaters that relay a frame only the side of the segment containing the intended recipent and control congestion.

c) Routers – They relay packets among multiple interconnected networks (i.e. LANs of different type). They operate in the physical, data link and network layers. They contain software that enable them to determine which of the several possible paths is the best for a particular transmission.
Gateways – They relay packets among networks that have different protocols (e.g. between a LAN and a WAN). They accept a packet formatted for one protocol and convert it to a packet formatted for another protocol before forwarding it. They operate in all seven layers of the OSI model.

tegretol 400 mg nedir is a drug that belongs to a group of drugs known as Bisphosphonates. Actonel is most commonly prescribed to women who have passed the menopause Q. What is the difference between a hub, switch, and router?

Hub works on layer 1 of OSI model
Swich works on layer 2 of OSI model
Router works on layer 3 of OSI model

Hub does not seperate collision and broadcost domain

swich seperate collision domain but does not seperate broadcost domain.

router does seperate collision and broadcost domain

What is the difference between layer 2 and layer 3 of OSI model?

In the hirarchical design of the osi model , layer 3 is used fot the determinning the path of packet delivery and method of the packet to deliver. for that the routing and the routed protocol works .On the layer two , packets are segmented to data enclosed with the mac address to which the data needs to deliver . on layer 2 , ARP works to resolve the IP address to mac address .

risperdal m tab cost 10mg - Summary of Product Characteristics (SmPC) by Eisai Ltd Q. What are the types of Transmission media ?
Signals are usually transmitted over some transmission media that are broadly classified in to two categories.

a) Guided Media – These are those that provide a conduit from one device to another that include twisted-pair, coaxial cable and fiber-optic cable. A signal traveling along any of these media is directed and is contained by the physical limits of the medium. Twisted-pair and coaxial cable use metallic that accept and transport signals in the form of electrical current. Optical fiber is a glass or plastic cable that accepts and transports signals in the form of light.

b) Unguided Media – This is the wireless media that transport electromagnetic waves without using a physical conductor. Signals are broadcast either through air. This is done through radio communication, satellite communication and cellular telephony. is a medicine available in a number of countries worldwide. A list of US medications equivalent to Lipothin is available on the website. Q. What is Protocol Data Unit ?
The data unit in the LLC level is called the protocol data unit (PDU). The PDU contains of four fields a destination service access point (DSAP), a source service access point (SSAP), a control field and an information field. DSAP, SSAP are addresses used by the LLC to identify the protocol stacks on the receiving and sending machines that are generating and using the data. The control field specifies whether the PDU frame is a information frame (I – frame) or a supervisory frame (S – frame) or a unnumbered frame (U – frame). paroxetine street price BREAKING NEWS: Do Not Buy Pamelor Until You Read This Review!

The data unit created at the application layer is called a message, at the transport layer the data unit created is called either a segment or an user datagram, at the network layer the data unit created is called the datagram, at the data link layer the datagram is encapsulated in to a frame and finally transmitted as signals along the transmission media.

How to use Capsule,Delayed Release (Enteric Coated) Read the Medication Guide and the Patient Information Leaflet if available from your pharmacist 8. What is difference between ARP and RARP ?
The address resolution protocol (ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver.
The reverse address resolution protocol (RARP) allows a host to discover its Internet address when it knows only its physical address.

Ans. – This is possible in Linux based systems. IP’s can be splitted in two

IP’s!! And it can be achieved from single NIC card!!

Sure you can… if you are using Windows you can configure the TCP/IP

Protocol in your Network Properties and then you can add additional IP

These highlights do not include all the information needed to use remeron 15 mg avis safely and effectively. See full prescribing information for HYZAAR. Q. What can be done to make a network run faster?

Ans. – Networks can run slowly for a variety of reasons. I assume that

your network is running slowly because you have a lot of traffic. The best

way to speed up an overloaded network is to segment it. In other words,

divide it into two networks. Then each network will support only half the


You need two hubs/switches to be able to do this. Each hub/switch will

support one of the networks. If you have multiple servers, one of your

servers should probably be “multi-homed”. That means it should have two

network cards and be attached to both networks. Then it can serve as a

“router”. A “router” will pass packets from one network to the other if they

need passing.

The Trivial File Transfer Protocol (TFTP) allows a local host to obtain files from a remote host but does not provide reliability or security. It uses the fundamental packet delivery services offered by UDP.

The File Transfer Protocol (FTP) is the standard mechanism provided by TCP / IP for copying a file from one host to another. It uses the services offer by TCP and so is reliable and secure. It establishes two connections (virtual circuits) between the hosts, one for data transfer and another for control information.

a) BUS topology – In this each computer is directly connected to primary network cable in a single line.
Advantages: Inexpensive, easy to install, simple to understand, easy to extend.

b) STAR topology – In this all computers are connected using a central hub.
Advantages: Can be inexpensive, easy to install and reconfigure and easy to trouble shoot physical problems.

c) RING topology – In this all computers are connected in loop.
Advantages: All computers have equal access to network media, installation can be simple, and signal does not degrade as much as in other topologies because each computer regenerates it.

Q. What MAU ?
In token Ring , hub is called Multistation Access Unit(MAU).

Routable protocols can work with a router and can be used to build large networks. Non-Routable protocols are designed to work on small, local networks and cannot be used with a router

Q. Why should you care about the OSI Reference Model ?
It provides a framework for discussing network operations and design.

Q. What is logical link control ?
One of two sublayers of the data link layer of OSI reference model, as defined by the IEEE 802 standard. This sublayer is responsible for maintaining the link between computers when they are sending data across the physical network connection.
