What are the advantages and disadvantages of client server networks?
client server network Advantages
- Centralized backup is possible.
- The use of dedicated servers improves overall system performance.
- Security on these networks is good because all shared resource centers are maintained.
- The use of dedicated servers also increases the speed at which resources are shared.
- All the required data is centered on one server, ie. ...
How to test a TCP server implementation?
- using create (), Create TCP socket.
- using bind (), Bind the socket to server address.
- using listen (), put the server socket in a passive mode, where it waits for the client to approach the server to make a connection
- using accept (), At this point, connection is established between client and server, and they are ready to transfer data.
How does TCP client-server work?
A TCP server listens on a well-known port (or IP address and port pair) and accepts connections from TCP clients. A TCP client initiates a connection request to a TCP server in order to setup a connection with the server. A real TCP server can accept multiple connections on a socket.
Is TCP used for client-server?
Using TCP binding, you can create both client and server portions of client-server systems. In the client-server type of distributed database system, users on one or more client systems can process information stored in a database on another system, called the server.
What is TCP in server?
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).
What is TCP client/server configuration?
Client/server architecture requires clients to communicate with the servers. That's where TCP/IP comes in—TCP/IP provides a standard way for clients and servers to exchange packets of data.
When would you use a TCP server?
Use TCP Server in conjunction with the Message Composer for applications that require a proprietary Ethernet communication protocol. Do not use this feature with communication protocols such as MODBUS, or any protocol with built-in support.
What is a TCP connection?
Transmission Control Protocol (TCP) – a connection-oriented communications protocol that facilitates the exchange of messages between computing devices in a network. It is the most common protocol in networks that use the Internet Protocol (IP); together they are sometimes referred to as TCP/IP.
Is TCP and IP same?
TCP and IP are two separate computer network protocols. IP is the part that obtains the address to which data is sent. TCP is responsible for data delivery once that IP address has been found.
What is TCP example?
Hence TCP is used in Text Communication due to its reliable transmission, error control, and in order receiving of the data. Example : Whatsapp, Instagram, Google Chat,iMessage. TCP is used in File transfer when we cannot tolerate the loss of data and receiving the data incorrect order is of utmost importance.

What is client and server with example?
Common examples of client-server networks include DNS (Domain Name Systems), web browsers and web servers, and FTP (file transfer protocol) clients. Most people experience client-server networking daily using computers, smartphones, and tablets connected to the Internet.
What is difference between HTTP and TCP?
While TCP contains information about what data has or has not yet been received, HTTP contains specific instructions on how to read and process this data once it arrives.
What is difference between TCP and HTTP?
While TCP contains information about what data has or has not yet been received, HTTP contains specific instructions on how to read and process this data once it arrives.
What is TCP and UDP?
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.
How TCP works step by step?
Let's step through the process of transmitting a packet with TCP/IP.Step 1: Establish connection. When two computers want to send data to each other over TCP, they first need to establish a connection using a three-way handshake. ... Step 2: Send packets of data. ... Step 3: Close the connection.
What port number is 8080?
Port number 8080 is usually used for web servers. When a port number is added to the end of the domain name, it drives traffic to the web server. However, users can not reserve port 8080 for secondary web servers.
What is TCP used for?
If we are creating a connection between client and server using TCP then it has few functionality like, TCP is suited for applications that require high reliability, and transmission time is relatively less critical. It is used by other protocols like HTTP, HTTPs, FTP, SMTP, Telnet. TCP rearranges data packets in the order specified.
What is TCP flow control?
TCP does Flow Control and requires three packets to set up a socket connection, before any user data can be sent. TCP handles reliability and congestion control. It also does error checking and error recovery. Erroneous packets are retransmitted from the source to the destination.
What does TCP/IP mean?
TCP/IP stands for “Transmission Control Protocol / Internet Protocol”. It is basically a network protocol that defines the details of how data is sent and received through network adapters, hubs, switches, routers and other network communications hardware. It was developed by the US department of defense for the purpose ...
What is the difference between TCP and TCP?
The only difference is that the data is sent across your network.
How does TCP/IP work?
TCP/IP connections work in a manner similar to a telephone call where someone has to initiate the connection by dialing the phone. At the other end of the connection, someone has to be listening for calls and then pick up the line when a call comes in. In TCP/IP communications, the IP Address is analogous to a telephone number and the port number would be analogous to a particular extension once the call has been answered. The “Client” in a TCP/IP connection is the computer or device that “dials the phone” and the “Server” is the computer that is “listening” for calls to come in. In other words, the Client needs to know the IP Address of whatever Server it wants to connect to and it also needs to know the port number that it wants to send and receive data through after a connection has been established. The Server only has to listen for connections and either accept them or reject them when they are initiated by a client.
What is the connection between a client and a server?
The “Client” in a TCP/IP connection is the computer or device that “dials the phone” and the “Server” is the computer that is “listening” for calls to come in.
How many ports does a TCP/IP address have?
The TCP/IP protocol is designed such that each computer or device in a network has a unique "IP Address" (Internet Protocol Address) and each IP address can open and communicate over up to 65535 different “ports” for sending and receiving data to or from any other network device.
Why was the TCP/IP protocol placed in the public domain?
The TCP/IP protocol was also placed in the public domain so that any software company could develop networking software based on the protocol.
What is the difference between an IP address and a port number?
The IP Address uniquely identifies the computer or device on the network and a "Port Number" identifies a specific connection between one computer or device and another (i.e between two IP Addresses).
What is tcpdump on Windows?
This isn't actual TCP output, which isn't in human-readable text. tcpdump is a program that reports on the TCP packets being sent and arriving on your computer. Odds are you see some traffic here.
How do clients and servers communicate?
Clients and servers communicate in a socket file . To communicate, a server and client read and write to the same socket file. You could say that their conversation "happens" in that file. To create our server, we'll just open a new socket file and wait for new data to appear there.
What port is Netcat on?
In fact, you can send TCP requests to this server on port 6789 from any kind of program you want. netcat is a linux program that can be used to send TCP requests from the command line. With your server still running, from another tab run this from the command line anywhere. $ nc localhost 6789.
What is the protocol used to interpret messages?
When a client sends a message to a server, it's just a string of bytes. Just as humans need a common language in order to communicate, clients and servers need a common understanding of how to interpret the bytes they are sending back and forth. The shared rules that allow them to interpret messages is called a protocol.
What is the name of the protocol that controls the communication between IP addresses?
The internet's other core protocol handles communication once IP has found the right destination. This is called Transmission Control Protocol, or TCP. Once the message arrives at its destination via the Internet Protocol (IP), TCP governs the conversation.
What is socket in computer?
Sockets are just files that are missing a special marker that tells a computer when the file ends. As a result, programs reading "socket" files get to the end of the file and then just keep waiting to see what the next line is going to be.
Does TCP have to be sent over the internet?
There's also an address on every line that represents your computer's address on your local network. TCP doesn't have to be sent over the internet, though. Let's use Ruby and TCP right now to create a simple server and client, and have them communicate right on our local machine.
What is client server architecture?
In the client-server architecture, when the client computer sends a request for data to the server through the internet, the server accepts the requested process and deliver the data packets requested back to the client. Clients do not share any of their resources. Examples of Client-Server Model are Email, World Wide Web, etc.
What happens when a client sends a request for data to a server through the internet?
In the client-server architecture, when the client computer sends a request for data to the server through the internet, the server accepts the requested process and deliver the data packets requested back to the client. Clients do not share any of their resources.
