TCP establishes a secure and reliable connection between two devices. This is possible because of the TCP’s 3-way handshake process, which occurs when two devices establish and close connections. There are three steps to both establishing and closing the connection, as the name implies. So, in this article, we’ll go through the TCP 3-way handshake process ...
Most broadband routers and other wireless access points contain an optional capability known as MAC address filtering, sometimes known as hardware address filtering. It increases security by limiting the devices that can connect to a network. MAC address filtering adds an additional layer of security by comparing the device’s MAC address to a list of ...
Circuit switching is a type of network configuration in which a physical path is acquired and set aside specifically for the purpose of connecting two endpoints in a network for the duration of a dedicated connection. Circuit switching is employed by typical voice phone services. Using different network devices, Packet switching divides data into smaller units called packets or blocks and transmits them across ...
If you are reading this article, you are most likely connected to the internet and viewing it at the Scaler Topics. Likely, you are currently utilizing Network Address Translation (NAT). More people now use the internet than ever anticipated, leading to the situation where the number of unique IP addresses provided by the IPv4, i.e.i.e.,232232 or 4,294,967,2964,294,967,296, is not enough. Network ...
Voice over Internet Protocol(VoIP) is a way of transmitting voice and multimedia over a network. VoIP enables users to place voice calls via their computer, smartphone, other mobile devices, dedicated VoIP phones, and WebRTC-capable browsers. VoIP is a technology that benefits consumers and businesses because it typically includes features not available on traditional phone services. ...
When the IP system was first introduced, finding a network and sending data to it was easier because the number of users on the internet was limited. As the number of users on the internet is increasing, sending a data packet to the computer you want in a network is becoming quite difficult these days. When a ...
Hubs and switches, both integral to networking, differ significantly in how they manage data traffic. Hubs simply broadcast data to all connected devices, leading to potential network congestion and inefficiency. In contrast, switches are smarter, forwarding data only to the specific device it’s intended for, improving network speed, and reducing unnecessary traffic. This fundamental difference ...
A web browser and a web server can “talk” to each other using the ISO Latin1 alphabet, which is ASCII with extensions for European languages, thanks to the Hypertext Transfer Protocol (HTTP), a protocol (a set of rules that describe how information is exchanged on a network). What is HTTP Protocol? Have you thought about what happens when we ...
Computer Network is the interconnection of multiple devices. Mainly there are three types of computer networks: LAN (Local Area Network), WAN (Wide Area Network), and MAN (Metropolitan Area Network). LAN is used to connect devices in a small area like a building, office, etc. MAN covers the devices connected within a town or a city. WAN covers a large geographical area ...
In the OSI model, the application layer is the layer closest to the end-user, implying that the application layer and the end-user can interact directly with the software application. The application layer isn’t an application. Instead, it’s a component within an application that manages how data is sent to and received from other devices. It’s an abstraction ...
