Understanding Computer Networks

About computer networks Every day, students and teachers at a state university sit in front of a PC or UNIX workstation, carefully check their e-mails, browse the World Wide Web, or download applications such as word processors and analysis packages I will do it. For most users, the magic wire with all these information is only electrical construction; the two wires are twisted together and finally crimped at the telephone connector. Today's world is based on a network of cable and telephone systems, but old and young engineers do not know what kind of structure they allow to communicate seamlessly worldwide .

In order to understand the mechanism of the block chain, you first need to understand the mechanism of the Internet. Abstract networks can explain the power of the Internet, but the Internet itself is part of the actual computer network. Once you understand how computer networks work, you can keep the concept of bit coins away from "tulips" and "unrealistic". After all, Bitcoin is now the largest public block chain in the world and the same can be said about the Internet if we are not so because we can not touch it.

I am talking about computer network, not LinkedIn type. Bitcoin is a global computer network consisting of users, nodes, and wallets. When considering the power of bit coins it is helpful to understand how the network is built. The network topology is the arrangement of the various components of the computer network. There are three types of control systems: centralized, distributed, and distributed. There is one server and many users in the centralized system. A distributed system has many servers and a large number of users. Bitcoin is a distributed system. In other words, it is distributed and redundant. Bitcoin is also known as a fault tolerant system. This means that if a server or computer fails, it will not occupy the entire network.

Before learning the connection method, you need to understand what the network is. Basically, a computer network connects two or more computers so that they can exchange data. This is also possible with wire, optical fiber, infrared camera, even radio waves. Because other methods are expensive, in most cases it is done via wires. With this network, companies can provide quality services at very high speed all over the world. Before learning more about the network, we need to understand some basic terms to better understand these concepts. First of all, we need to understand the difference between hardware and software. Hardware is what you actually touch the computer. This includes computer components such as monitors, printers, keyboards, hard drives, mice, CD-ROMs, sound cards, and video cards. The software is the actual information on the computer's hard drive or disk, CD, or DVD.
