What is TCP and IP for kids?
TCP is part of the popular "TCP/IP" combination used by the Internet. The Internet Protocol, or IP, makes sure data on the internet gets to the right place. Then TCP makes sure the data is put in the right order, and none of it is missing. TCP also helps to control traffic on the internet so it does not get overloaded.

How does TCP work simple?
How it works. TCP/IP is a two-layered program: the higher layer (TCP) disassembles message content into small "data packets" that are then transmitted over the Internet to be re-assembled by the receiving computer's TCP back into the message's original form.
What is TCP and UDP for dummies?
TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. A key difference between TCP and UDP is speed, as TCP is comparatively slower than UDP. Overall, UDP is a much faster, simpler, and efficient protocol, however, retransmission of lost data packets is only possible with TCP.
Why is TCP IP still used today?
TCP/IP is important because whole internet runs over it. This is the protocols using which 2 different network Elements communicate with each other. Without the TCP/IP the data communication and Internet or Inter-Networking of the devices is not possible.
What are the main function of TCP IP?
The main function of TCP/IP is that it governs how the information is sent and received in the form of packets between source and destination. So in short, we can say that TCP defines the communication in a network and how to send data in the form of packets.
What are the 4 layers of TCP IP?
4 The TCP/IP Protocol Stack is made up of four primary layers: the Application, Transport, Network, and Link layers (Diagram 1).
What are the three main jobs of TCP?
Connection Establishment, Management and Termination: TCP provides a set of procedures that devices follow to negotiate and establish a TCP connection over which data can travel.
What is UDP in simple words?
The User Datagram Protocol, or UDP, is a communication protocol used across the Internet for especially time-sensitive transmissions such as video playback or DNS lookups. It speeds up communications by not formally establishing a connection before data is transferred.
Why UDP port is used?
Because UDP ports are connectionless protocols, they save a lot of time by not establishing connections before sending out data packets, which comes in handy for time-sensitive services and where data is received in real-time. UDP ports are used in video, voice, and game streaming.
What's the difference between TCP IP and UDP?
TCP is connection-oriented while UDP is connectionless The connection is established via a three-way handshake. The client sends a synchronization request, the server sends back an acknowledgment, and the client returns a synchronization acknowledgment in response. Comparatively, UDP is a connectionless protocol.
What is a TCP IP address?
TCP/IP includes an Internet addressing scheme that allows users and applications to identify a specific network or host with which to communicate. An Internet address works like a postal address, allowing data to be routed to the chosen destination.
Why is it called TCP IP?
The name “TCP/IP” refers to an entire suite of data communications protocols. The suite gets its name from two of the protocols that belong to it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP).
What does TCP/IP stand for?
TCP/IP stands for Transmission Control Protocol/Internet Protocol. TCP/IP is a set of standardized rules that allow computers to communicate on a network such as the internet.
What does TCP/IP do, exactly? And how does it work?
Department of Defense to specify how computers transfer data from one device to another. TCP/IP puts a lot of emphasis on accuracy, and it has several steps to ensure that data is correctly transmitted between the two computers.
Are my data packets private?
No. When the packets are being transmitted between computers, they are vulnerable to being seen by others. That’s one reason why you are advised to avoid public Wi-Fi networks when sending data that must stay private, and to use encryption.
How can I tell what my TCP/IP address is?
Each device has its own TCP/IP address. Usually the device can communicate automatically , but sometimes you need to manually provide your TCP/IP address. How you go about finding your IP address depends on your operating system.
What is the difference between static and dynamic IP addresses?
The differences between types of IP addressing are transparent to you as a casual user – and the fact that you don’t need to know much about it is among TCP/IP’s strengths. Usually these matters are managed by whoever sets up your computer operating system or mobile device. But for clarity: 1 Static IP addresses stay the same all the time. They are like the fixed address on your house, an unchanging address. 2 Dynamic IP addresses change, or at least they are designed to change. When a computer system uses a dynamic IP address, it announces, “This is where you can find me!” to the local network – rather like the “address” of a hotel room, where the hotel knows how to find you. To learn more about this distinction, see Static vs. dynamic IP addresses. 3 You may have heard of cities where the population is growing so quickly that they’ve had to create new area codes so new arrivals could get telephone numbers. With the ever-increasing number of connected devices, TCP/IP had a similar problem -- the internet was basically running out of IP addresses. So a new version of IP address called IPv6 was developed as an alternative to the existing IPv4 addresses. Here’s a more in-depth look at the differences between IPv4 vs. IPv6 addresses.
How many layers are there in TCP/IP?
The four layers of the TCP/IP model. TCP/IP is a datalink protocol that is used on the internet. Its model is split into four distinct layers. Used together, they can also be referred to as a suite of protocols.
What is protocol in human terms?
A protocol is an agreed-upon set of rules. In human terms, we use social protocols to know how to behave and communicate with other people. Technologies have their own ways of setting communication rules, such as the telegraph using Morse code or a CB radio using codes like “10-4.”.
How are TCP/IP and IP different?
For example, IP is a low-level internet protocol that facilitates data communications over the internet. Its purpose is to deliver packets of data that consist of a header, which contains routing information, such as source and destination of the data, and the data payload itself.
Why are TCP and OSI models similar?
The functions performed in each model are also similar because each uses a network layer and transport layer to operate. The TCP/IP and OSI models are each mostly used to transmit data packets. Although they will do so by different means and by different paths, they will still reach their destinations.
What is the application layer?
The application layer provides applications with standardized data exchange. Its protocols include HTTP, FTP, Post Office Protocol 3, Simple Mail Transfer Protocol and Simple Network Management Protocol. At the application layer, the payload is the actual application data.
What is TCP/IP protocol?
TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP is also used as a communications protocol in a private computer network (an intranet or extranet).
How many bytes are in an IP packet?
The maximum size of a single IP data packet, which contains both the header and the data, is between 20 and 24 by tes long. This means that longer strings of data must be broken into multiple data packets that must be independently sent and then reorganized into the correct order after they are sent.
Why is TCP/IP stateless?
Collectively, the TCP/IP suite of protocols is classified as stateless, which means each client request is considered new because it is unrelated to previous requests. Being stateless frees up network paths so they can be used continuously.
Which is better: OSI or TCP/IP?
Therefore, TCP/IP is a more practical model.
What is a Protocol Suite ?
A protocol suite is a collection of protocols that are designed to work together.
What is a switch router?
A switch operates at the Ethernet level and is a level 2 device. Because a router operates at the networking layer it doesn’t need to support the upper layer application protocols like HTTP,FTP etc. The router works on network address which are part of the networking protocol ( IP or IPX ).
What is TCP protocol?
TCP (Transmission control protocol) is a connection orientated protocol and is used to provides a reliable end to end connection.
What is the problem with the 'Inflexible' approach?
The problem with this approach is that it very inflexible, as any changes require changing the entire application and protocol software.
Why is it important to understand the interfaces between the interfaces?
What is important to understand is that the interfaces between the interfaces are well defined so that it is theoretically possible to replace a particular protocol with another one that operates at that level.
What is the main protocol used for networking?
IP (Internet Protocol) – This is the main networking protocol. There are two version of IP ( IPv4 and IPV6 ). ARP (address resolution Protocol) -Translates an IP address to a MAC or physical address.
What is Ethernet protocol?
Ethernet is a 2 layer protocol/standard covering the physical and data link layer, shown in the diagram above.
Why does TCP assign more information to the data coming from the upper layer?
Here the protocol TCP assigns some more information (like sequence number, source port number, destination port number etc) to the data coming from upper layer so that the communication remains reliable i .e, a track of sent data and received data could be maintained.
How does TCP work?
TCP divides the data (coming from the application layer) into proper sized chunks and then passes these chunks onto the network. It acknowledges received packets, waits for the acknowledgments of the packets it sent and sets timeout to resend the packets if acknowledgements are not received in time.
What is the protocol suite used for?
Communications between computers on a network is done through protocol suits. The most widely used and most widely available protocol suite is TCP/IP protocol suite. A protocol suit consists of a layered architecture where each layer depicts some functionality which can be carried out by a protocol. Each layer usually has more than one protocol options to carry out the responsibility that the layer adheres to. TCP/IP is normally considered to be a 4 layer system. The 4 layers are as follows :
What is the layer of network interface?
This layer is also known as network interface layer . This layer normally consists of device drivers in the OS and the network interface card attached to the system. Both the device drivers and the network interface card take care of the communication details with the media being used to transfer the data over the network. In most of the cases, this media is in the form of cables. Some of the famous protocols that are used at this layer include ARP (Address resolution protocol), PPP (Point to point protocol) etc.
What is the purpose of the Internet layer?
This layer is also known as Internet layer. The main purpose of this layer is to organize or handle the movement of data on network. By movement of data, we generally mean routing of data over the network. The main protocol used at this layer is IP. While ICMP (used by popular ‘ping’ command) and IGMP are also used at this layer.
What is the transport layer?
This layer provides backbone to data flow between two hosts. This layer receives data from the application layer above it. There are many protocols that work at this layer but the two most commonly used protocols at transport layer are TCP and UDP.
How many layers are there in TCP/IP?
Each layer usually has more than one protocol options to carry out the responsibility that the layer adheres to. TCP/IP is normally considered to be a 4 layer system. The 4 layers are as follows : Application layer. Transport layer.
