The American standard for DS0 is 64 Kbs, the European standard is 32 Kbs. The Americans pushed for an ATM payload of 64 Bytes while the Europeans pushed for 32 Bytes. To come to a compromise, the committee added 64 + 32 = 96. They then divided this sum by 2 for a result of 48. A 5 Byte header was added for a total of 53 Bytes.
What else can I help you with?
ATM networks transfer all data as fixed-length cells consisting of how many bytes?
53 bytes
Difference between ATM and frame relay?
ATM as well as frame relay are switched WANs. Frame relay protocol was designed to replace X.25 . ATM is advantageous as it is a cell network and a cell network uses the cell as a basic unit of data exchange and are small and fixed size block of information .
How many kilobytes are in 0.53 megabytes?
.53 MB (which is MegaBytes, or millions of bytes) equates to 542.7199707031 KiloBytes (which is thousands of bytes.)
What port dns use?
Port 53
When a client computer sends a request to a Domain Name System (DNS) server, what type of packet is sent?
DNS primarily uses the User Datagram Protocol (UDP) on port number 53 to serve requests. DNS queries consist of a single UDP request from the client followed by a single UDP reply from the server. When the length of the answer exceeds 512 bytes and both client and server support EDNS, larger UDP packets are used.
How many bytes consists of ATM cell?
53 bytes long
What is the cell size of ATM?
The cell size of Asynchronous Transfer Mode (ATM) is fixed at 53 bytes. This includes a 5-byte header for addressing and routing information, and a 48-byte payload for user data. The use of fixed-length cells allows for efficient switching and multiplexing of data.

What is the difference between the ATM and ip?
ATM has (i) Fixed cell size, (ii) Implemented to meet the transport requirements for LAN,MAN and WAN applications, (iii) Connection-oriented, (iV) Cell size is fixed and is of 53 bytes 5 for header and 48 for payload, (V) Packet switching on private network that operate on data link layer on OSI. Whereas IP has (i) Variable cell size, (ii) Allow voice, data, fax and video signals to share a common networking infrastructure, (iii) Connection less, (iV) Cell size is upto 65535 bytes,and (V) Network addressing that operate on network layer on OSI frame relay.

What Protocol and Port is used by DNS for responses larger than 512 bytes?
TCP 53
Which of the following WAN technologies uses 53 byte fixed-length cells?
ATM
Where is ATM technology used?
I'm assuming you mean Asynchronous Transfer Mode, not Automatic Teller Machine. It's used by Telcos, often as part of the SONET optical fibre system. Its main features are its 53-byte cell size and its circuit-oriented design which suits the needs of Telecommunications. Although ATM was "very fast" when first introduced, it's been overtaken by Ethernet over fibre in its various forms. Ethernet can now reliably work at tens of gigabits, and ATM is often "packaged" into Ethernet frames for transport.
What is PTR record?
A PTR record is essentially the opposite of an A record. A records resolve names to IP addresses. PTR records resolve IP addresses to names. A record = give me a name I'll give you an IP PTR record = give me an IP I'll give you a name Try it out in windows: ping "www.yahoo.com" Here is what I got: ------------------------------------------------------------------------------------- F:\>ping www.yahoo.com Pinging www-real.wa1.b.yahoo.com [69.147.76.15] with 32 bytes of data: Reply from 69.147.76.15: bytes=32 time=14ms TTL=53 Reply from 69.147.76.15: bytes=32 time=11ms TTL=53 Reply from 69.147.76.15: bytes=32 time=65ms TTL=53 Reply from 69.147.76.15: bytes=32 time=12ms TTL=53 --------------------------------------------------------------------------------------- now do a "ping -a IP-ADDRESS" which will spit you back the name attached to that IP ---------------------------------------------------------------------------------------- F:\>ping -a 69.147.76.15 Pinging f1.www.vip.re1.yahoo.com [69.147.76.15] with 32 bytes of data: Reply from 69.147.76.15: bytes=32 time=19ms TTL=53 Reply from 69.147.76.15: bytes=32 time=88ms TTL=53 Reply from 69.147.76.15: bytes=32 time=12ms TTL=53 Reply from 69.147.76.15: bytes=32 time=46ms TTL=53 Ping statistics for 69.147.76.15: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 12ms, Maximum = 88ms, Average = 41ms ------------------------------------------------------------------------------------------- Your accessing PTR records to do this. ... and just so you beileve me try a "ping 69.147.76.15" and check the results FYI: if your doing a ping -a to an intranet host you need to configure reverse lookup for it to work properly.
What is packet forwarding?
Packet forwarding in simple terms is the forwarding of packets from one node to another from networking point of view. For example, a router or a switch. These networking devices make routing devices with the help of their routing tables and then select an outgoing interface. After that they make some changes in the packet header and push (forward) the packet to the selected interface. In case you don't know the meaning of packet. Packer is the smallest unit of size in networking. Different networks has different packet size. For example, in ATM Networks the packet size is of 53 Bytes.
How much is 53 KB?
53 Kilobyte's isn't very much but can be the equivelant of 53,000 bytes, 1000 KB is required to take it up to the next level of 1 MB.
