What is the process of deep packet inspection?
Deep packet inspection is a type of computer network packet filtering. Deep packet inspection examines the data part of a package as it passes through an inspection point. Factors such as viruses, spam, and intrusions determine whether the packet passes or needs to be rerouted to a different destination. Sometimes the packet is rerouted for the collection of statistical purposes.
What Part of a computer that plays music and data?
A computer can only produce sound if it contains the right hardware. These come in the forms of sound cards or sound chips. In most cases these devices only convert the sound data from digital to analogue signals - the computer itself reads the binary data and decodes it into a form understandable by humans.
What part of the computer collects data from people and devices?
Input devices connect to the computer and they pass data into the Processor where it can be processed.
Which part of an ip packet does the router use to make routing decisions?
the network portion of the destination ip address
Backing up your data on a regular basis is a part of the process.?
maintenance
Which part of a data packet contains error-checking information?
The trailer
The telephone system uses packet-switching technology where as the Internet uses circuit-switching technology?
telephone system uses packet switching because packet switching is reiable. In a packet switching when a packet(some part of total information) is lost then the packet can be retransmitted. But in case of circuit switching if any part of data is lost anytime then total data will be retransmitted. Again circuit swithing is more speedy with compare to packet switching.In order to increase the bit rate (more speed) circuit switch is prefered in Internet.

What are the Exception being the part composite data types?
Well, honey, the exception to being a part of composite data types is being a standalone data type. In simpler terms, if you're not part of a group, you're not a composite data type. It's like being the lone wolf in a pack of wolves - you stand out, whether you like it or not.
Statistical treatment of data?
It is a part of your thesis where your gathered data is being solved...
What is a cell nucleolus?
A cell nucleolus is the part in the middle of the cell which contains data and DNA from that cell
Is it true or false that A linked list is a collection of nodes?
It is true that a linked list is a collection of nodes.And a node contains data part and a link part which contains address of the next node.
What is packet fragmentation?
If a device receives a packet which is larger than it is set to forward, it will split the packet and pad the part packet with zeros. This increases the number of packets transmitted on the next hop.
What part of speech is the word packet?
Noun.
What is deep packet filtering?
Deep packet filtering first examines the data part (and possibly also the header) of a packet as it passes an inspection point, searching for protocol non-compliance, viruses, spam, intrusions or predefined criteria to decide if the packet can pass or if it needs to be routed to a different destination, or for the purpose of collecting statistical information. This differs from "stateful packet inspection" (shallow filtering) where only the type of traffic and possibly the source and destination are inspected, not the contents of the traffic.
What is a Packet data session?
On the Internet, the network breaks an e-mail message into parts of a certain size in bytes. These are the packets. Each packet carries the information that will help it get to its destination -- the sender's IP address, the intended receiver's IP address, something that tells the network how many packets this e-mail message has been broken into and the number of this particular packet. The packets carry the data in the protocols that the Internet uses: Transmission Control Protocol/Internet Protocol (TCP/IP). Each packet contains part of the body of your message. A typical packet contains perhaps 1,000 or 1,500 bytes. Each packet is then sent off to its destination by the best available route -- a route that might be taken by all the other packets in the message or by none of the other packets in the message. This makes the network more efficient. First, the network can balance the load across various pieces of equipment on a millisecond-by-millisecond basis. Second, if there is a problem with one piece of equipment in the network while a message is being transferred, packets can be routed around the problem, ensuring the delivery of the entire message. Depending on the type of network, packets may be referred to by another name: frame block cell segment Most packets are split into three parts: header - The header contains instructions about the data carried by the packet. These instructions may include: Length of packet (some networks have fixed-length packets, while others rely on the header to contain this information) Synchronization (a few bits that help the packet match up to the network) Packet number (which packet this is in a sequence of packets) Protocol (on networks that carry multiple types of information, the protocol defines what type of packet is being transmitted: e-mail, Web page, streaming video) Destination address (where the packet is going) Originating address (where the packet came from) payload - Also called the body or data of a packet. This is the actual data that the packet is delivering to the destination. If a packet is fixed-length, then the payload may be padded with blank information to make it the right size. trailer - The trailer, sometimes called the footer, typically contains a couple of bits that tell the receiving device that it has reached the end of the packet. It may also have some type of error checking. The most common error checking used in packets is Cyclic Redundancy Check (CRC). CRC is pretty neat. Here is how it works in certain computer networks: It takes the sum of all the 1s in the payload and adds them together. The result is stored as a hexadecimal value in the trailer. The receiving device adds up the 1s in the payload and compares the result to the value stored in the trailer. If the values match, the packet is good. But if the values do not match, the receiving device sends a request to the originating device to resend the packet. As an example, let's look at how an e-mail message might get broken into packets. Let's say that you send an e-mail to a friend. The e-mail is about 3,500 bits (3.5 kilobits) in size. The network you send it over uses fixed-length packets of 1,024 bits (1 kilobit). The header of each packet is 96 bits long and the trailer is 32 bits long, leaving 896 bits for the payload. To break the 3,500 bits of message into packets, you will need four packets (divide 3,500 by 896). Three packets will contain 896 bits of payload and the fourth will have 812 bits. Here is what one of the four packets would contain: Each packet's header will contain the proper protocols, the originating address (the IP address of your computer), the destination address (the IP address of the computer where you are sending the e-mail) and the packet number (1, 2, 3 or 4 since there are 4 packets). Routers in the network will look at the destination address in the header and compare it to their lookup table to find out where to send the packet. Once the packet arrives at its destination, your friend's computer will strip the header and trailer off each packet and reassemble the e-mail based on the numbered sequence of the packets.
What part of a packet is used to get to destination?
Destination address
