Understanding the Differences between TCP/IP and OSI Models
TCP and IP are the two main network protocols or communications standards of the internet. Where TCP defines how different applications can communicate over reliable channels across a network, IP regulates how devices connected to the internet can transmit and receive data over the network or an interconnected set of networks. In other words, IP defines routing and addressing while TCP defines how the connected peripherals can communicate across the IP-mediated link without any data loss. The OSI or Open Systems Interconnection model, on the contrary, defines how the different tasks related to the network communication can be segregated across multiple layers of software and hardware components. It was developed by the International Organization for Standardization (ISO) as the ISO/IEC[…]

Everything You Need to Know About a Subnet Mask
A subnet, or sub-network, refers to a network within a network, which is assigned to make the parent network more efficient. Administrators use subnets to facilitate effective network traffic over a shorter distance without requiring the signals to pass through multiple routers to reach the destination. A subnet mask is a 32-bit number like an IPv4 address but it masks the IP address for internal purposes and divides the IPv4 address into network address and host address. For instance, network routers employ subnet masks to route data packets to the specified destinations. In general, a subnet mask comprises of network bits that are set to 1s and host bits that are set to 0s. In any network, there are two[…]

The Dangers Of Public IPs – Infographic
A public IP address allows connecting your device to the internet and communicating with other devices. With it, your internet-connected device can be located. There may be benefits to using it, but this move also has many disadvantages. For one, the address itself is more expensive than before because of its shrinking supply. This means you may have to pay more money to a public IP address provider if your enterprise requires it. There are other downsides to it, so you must weigh these against its benefits, while considering your requirements, to make informed decisions. Here is an infographic to help you with that decision-making process.
