1. A set of rules that define the way data is transferred between different agents. A data transmission protocol defines the physical media to the composition of the message itself, possible going through error detection and correction.
What is IP communication?
IP stands for “Internet Protocol,” which is the set of rules governing the format of data sent via the internet or local network. In essence, IP addresses are the identifier that allows information to be sent between devices on a network: they contain location information and make devices accessible for communication.
What is the role of TCP?
TCP is used for organizing data in a way that ensures the secure transmission between the server and client. It guarantees the integrity of data sent over the network, regardless of the amount. For this reason, it is used to transmit data from other higher-level protocols that require all transmitted data to arrive.
What are the types of IP address?
There are four types of IP addresses: public, private, static, and dynamic. An IP address allows information to be sent and received by the correct parties, which means they can also be used to track down a user’s physical location.
How does an IP work?
IP information is attached to each packet, and this information helps routers to send packets to the right place. Every device or domain that connects to the Internet is assigned an IP address, and as packets are directed to the IP address attached to them, data arrives where it is needed.
What is TCP and its types?
TCP confirms that a packet has reached its destination by establishing an end-to-end connection between sending and receiving hosts. TCP is therefore considered a “reliable, connection-oriented” protocol.
What are the advantages and disadvantages of TCP?
Advantages and Disadvantages of the TCP/IP Model
- It is an industry–standard model that can be effectively deployed in practical networking problems.
- It is interoperable, i.e., it allows cross-platform communications among heterogeneous networks.
- It is an open protocol suite. …
- It is a scalable, client-server architecture.
What is netstat used for?
The network statistics ( netstat ) command is a networking tool used for troubleshooting and configuration, that can also serve as a monitoring tool for connections over the network. Both incoming and outgoing connections, routing tables, port listening, and usage statistics are common uses for this command.
What are the three types of addresses?
Some link-layer protocols define three types of addresses: unicast, multicast, and broadcast. Each host or each interface of a router is assigned a unicast address. Unicasting means one-to-one communication.
What can IP reveal?
Law enforcement has used IP addresses to establish the locations of individuals they are looking for. They can discover all sorts of information such as what is being posted on message boards, online photo sharing, legal and health issues, sexual tendencies, in fact, anything that your web browsing reveals.
