UDP is the faster protocol as it doesn't wait for 
acknowledgement so it is not at all having reliability as 
compared to TCP.

tcp

udp is faster..mainly used for video and audio streaming ( 
Rstp)

tcp

UDP is faster then TCP in data transmission.

Compare 2 TCP , UDP is a faster & it is used for download 
uplooud vedio's ...... un reliable

UDP is faster than TCP because it is connectionless and need
not wait for connection setup  and ACK.

TCP is faster than UDP.

UDP is faster protocol since it has no acknowledgement 
signal.....

UDP is faster than TCP bcoz it is connection less protocol 
and it also does not wait for acknowledgement . Therefore 
it is specially used for video signals transmission .

how many protocals are there?give me(20)important protocals?
plz it is important to me plz plz.....

UDP is definitely faster than TCP. Thats why it is mainly 
used for video and streaming audio. Speed!

The reason UDP is fater than TCP is because UDP does not do 
error correction and flow control.

7 Layers
1 application layer
2 Presentation layer
3 Section layer
4 Transport layer
5 Network layer
6 Data link layer
7 physical layer

In the above answer the 3rd layer is not correct.It should
be session layer

Network Layer are 7
1.Physical Layer 
2.Data Link Layer 
3.Network Layer

Hi all,

I am bit confused about this question,Network itself one of 
the Layer in OSI model if am not wrong,and there is no sub 
layers as such in network layer
 However Network layer is called as layer 3 in OSI model 
and it works on packed level

Thank you 
 Surya MR

3 layers

Network Layer is itself a layer who ediot asked this 
ques.!!!!!!!!!

frahatu first of all read OSI layer seriously.
Network layer is also called Layer 3 of OSI model used for 
routing purpose.It is itself one of the layer, so how can u 
ask without knowing this. I think by mistake u write this.

Just keep in ur mind that Network layer is the third layer 
of OSI layer Arcitecture

1 physical

2data link

There r 7 layers.

check the question

Network layer is also called Layer 3 of OSI model.
network layer no have any layers.
your method of asking the question is wrong.

network layer itself is layer 
im sure 4 layers in tcp/ip and 7 layers in osi model

Hi all,

 This is confusing question.Dont be confused because the 
quesioner wanna to know ur IQ. Network layer is one of the 
layer of OSI Model and its place is 3rd in OSI MOdel.
  
If question is like this : How many layers in Network? Then 
according to me , it's answer is 7.

This is not a valid question. The Network Layer is a layer 
on its own and does not contain any sublayers. The question 
should be: How many layers are there in the OSI Reference 
Model and what are they?

Two types of OSI network-layer services are available: 
Connectionless Network Service (CLNS) and Connection-
Oriented Network Service (CONS). CLNS uses a datagram data 
transfer service and does not require a circuit to be 
established before data is transmitted.

1)application
2)Transport
3)Internet
4)Network Access

taht is not avalid quesion bcz netwok layer itself a layer

question is litle bit confused

network layer has 2 layer
1,phisical layer
2,logical layer

CLNS and CONS is used to define the protocol's function in 
network layer.
the protocol TCP (CONS)and this is not a layer.
UDP(CLNS) this defines UDP is connectionless protocol and 
again this is not a layer.

7

Pls note network layer is itself a part of OSi layer I mean 
to say Layer no-3 .

1.Physical Layer 
2.Data Link Layer 
3.Network Layer 
4.Transport Layer

describe OSI layers ?

Hi
This is kartik from d.dun.
Network Layer are of 7 types.
1.Physical Layer 
2.Data Link Layer 
3.Network Layer 
4.Transport Layer 
5.Session Layer 
6.Presentation Layer 
7.Application Layer

only network layer
question may be wrong
two network services are avilable
conection less(UDP) and connection oriented(TCP).....

i am only know about subnetting concept is used to connect 
more networks from hostaddress using ipaddress and it can 
produce more network connection.

sub-netting means we r going to divide a single network to
many different sub network by borrow host bit as a network
bits in subnet mask. after subnetting the default subnet
mask has been increasing.(but have same prefixes)  

basically when we have a single network address and we need
more than one network address for security, network
broadcast Strom, load balance, remote sites etc. reason then
we are going for subnetting.

I only know about UDP is unreliable and connectionless 
protocol.And TCP/IP protocol is connection oriented and 
reliable.i want some more advantages and disadvantages and 
UDP where its used.

UDP: It doesn't wait for acknowledgement as like TCP/IP so 
it is unreliable protocol.

UDP is usually used in where communication needs to be fast 
like in DNS and DHCP.

The first thing is UDP is connection less where as TCP is 
connection  oriented.The broadcasting and multicasting 
software is available in the UDP only.Why because it is 
connection less hence we can broadcast the packets very 
easily,no need to wait for connection like in tcp,which 
takes more delay.

there are a few TCP/IP protocols that are usually called 
the “core” of the suite, because they are responsible for 
its basic operation. Which protocols to include in this 
category is a matter of some conjecture, but most people 
would definitely include here the main protocols at the 
internet and transport layers: the Internet Protocol (IP), 
Transmission Control Protocol (TCP) and User Datagram 
Protocol (UDP). These core protocols support many other 
protocols

TCP protocols may TCP over IP4 ,TCP over IPV6,TCP over VLAN.
UDP protocols may UDP over IP4 ,UDP over IPV6,UDP over VLAN.

TCP/IP is layer suite of protocols, it is a combination of 
2500 protocols .......like udp , tcp,ip,smtp, 
pop,ftp,telnet,arp,rarp and so on.....

A utility to determine whether a specific IP address is 
accessible. It works by sending a packet to the specified 
address and waiting for a reply. PING is used primarily to 
troubleshoot Internet connections. There are many freeware 
and shareware Ping utilities available for personal 
computers. 
It is often believed that "Ping" is an abbreviation for 
Packet Internet Groper, but Ping's author has stated that 
the names comes from the sound that a sonar makes.

PING Packet Internet Gropher...

Ping is a program that sends a series of packets over a 
network or the Internet to a specific computer in order to 
generate a response from that computer.
 
ex:windows key+r 
type: cmd
ping 192.168.0.1

packet internet gropher a command which is used to know 
whether  a particular IP address is conneted to internet or 
not.

PING-that is packet internet gropher it is a command which 
is used to know physical connectivity between two computers 
or two routers or two network what ever u want to check ..

it is just like tracert command ...ok !

u may check the physical connection with the help of PING 
or TRACERT both are used to trobleshot the network prob.

ping is a windows network command. it's mainly used to check
that a desired system was connected to this system or not. 

for Ex:
 
in a LAN network if u wish to check ur colleague system was
connected to ur system or not by typing their ip

ex:windows key+r 
type: cmd
ping 192.168.0.1

Ping is a basic Internet program that allows a user to
verify that a particular IP address exists and can accept
requests. The verb ping means the act of using the ping
utility or command. Ping is used diagnostically to ensure
that a host computer you are trying to reach is actually
operating.

Ping is a program that sends a series of packets over a
network or the Internet to a specific computer in order to
generate a response from that computer. The other computer
responds with an acknowledgment that it received the
packets. Ping was created to verify whether a specific
computer on a network or the Internet exists, and is connected.

PING :- It stands for PACKET INTERNET GROPHER. It is a 
network layer protocol.It is use for send a request to 
destination for a perticular system connected or not.

Ping is a computer network tool used to test whether a 
particular host is reachable across an IP network; it is 
also used to self test the network interface card of the 
computer. It works by sending ICMP “echo request” packets 
to the target host and listening for ICMP “echo response” 
replies. Ping estimates the round-trip time, generally in 
milliseconds, and records any packet loss, and prints a 
statistical summary when finished.

ping is a command to test that the ip or any host is 
reachable or not it use icmp protocol to determine the host 
according to books it is abbriviated form of packet

ip addresses while the one released by IEEE (through the 
ISP) are dynamic ip addresses

static address is given by administrator manually

dynamic addres is given by DHCP server

static ip manually assign ip address , where as dynamic ip 
is automatically assign ip address to the pc

We can Define the range in DHCP and the DHCP will the the 
IP of all host system automaticly 
But in static IP the Ip will be provide by adminstrator 
manuly

Static Ip is assigned manually
Dy.Ip assigned by DHCP Server using its IP range.
Static can be modified as needed
Dy.IP will be ther till its Lease Duration
St.Ip may be Permanant
Dy.Ip will be changing after Lease Duration

Static Ip is assigned manually,Static can be modified as
needed,Static Ip may be Permanant.dynamic ip assigned by
DHCP Server using its IP range,dynamic ip will be ther till
its Lease Duration,dynamic Ip will be changing after Lease
