Network address translation

Answer 3:- A:- When it is very expensive and slow to access the external network then we use Forwarding name server . What is does keep the records of frequently visited sites in local DNS cache. This improves the efficiency . B:- Round Robin mechanism is used for load balancing . DNS hold maximum record of entry. In round and robin mechanism it allocate IP address to the requested client as per the availability and making the server highly available . Answer 4:- "in.addr-arpa" is used to…

INTRODUCTION A network refers to a group of computers and other devices that are connected together usually by communication lines. The internet is a global network connecting millions of computers throughout the world allowing them to send and receive information. When it comes to multimedia communication both the internet and the network are vital platforms since multimedia elements such as graphics, videos, texts and audio need to be sent from one computer to another. As we know sending a…

Text Data Computers represent information using bits. A bit string is a sequence of zero or more bits. This information is encoded by the sender and will be transmitted. The receiver then decodes the information. Data sent may be corrupted along the way because noise may interfere every time an information is transmitted to any channel. A channel is the physical medium through which information is transmitted. Examples of channels include telephone lines, internet cables, fiber optic lines,…

Internet architecture is basically a huge network of thousands of networks communicating using a common protocol. The Internet sends a transmission to a host computer that sends it on to another computer that is connected to the host computers network. If the receiving computer is not connected to the host computers network, the host computer sends it on to another computer that can then send it to the receiving computer. It is not unusual for the message to pass through several routers before…

Question 1 1.1)T.C.P(transmittion control protocol)-It is the language the computer uses to acess the internet. It is made up of protocalls which are made to establish a network of networks and provide a host with access to the internet. 1.2)I.P(Internet Protocol)-It is the way or protocol of how data is sent from one computer to another computer on the internet. 1.3)Physical Layer-the Physical layer is the interface between the medium and the device.It is made to transfer raw bits over a…

will help you decide if the existing internetwork is in good enough shape to support new enhancements? keeping a track of round trip response time, regular checkups of major routers, firewalls and switches, identifying sources and destinations of network traffic, analyzing its direction and balancing the data travel between source and destination are the some important factors. Documentation should be done for Data stores and traffic flows, the number of stations, average time a station is idle…

though, the analog data will go through the PCM (Pulse Code Manipulation) process, where the analog data is quantized into binary encoding using samples from analog signals. The digital packets containing the binary encoding will then pass through the network from node to node along a path. At each node, the packet will be briefly stored and then forwarded on to the next node until it arrives at the receiver’s destination. The data is sent over the telephone line digitally. The data will contain…

interface between the network layer (IP etc.) and the Data Link layer (Ethernet, Token Ring etc.) It’s the standard for the upper Data Link layer sublayer, also known as the Logical Link Control layer. It’s responsible for flow and error control. The Data Link layer wants to send some data over the network, 802.2 LLC helps make this possible. b. 802.3 – Ethernet 802.3 is the standard which Ethernet operates by. The original 802.3 standard is 10mbps. Commonly, Ethernet networks transmit data in…

Implementing Firewall Filter Implementing firewall filters on a network makes the network free from attackers and very secured. Some of the boundaries that I will consider using on my firewall will be blocking ports on the network. First of all I will establish a new FTP session which the will initiate a connection to an FTP server that listens on TCP port 21 by default. This will help users on the network to login with user name and password before any data to port 21 will accepted. I…
