Description

C omputer Networking is simply the formation of a computer network. A computer network can be defined as the collection of computers, printers, and other equipment that are connected (wired or wireless), with the ultimate aim of fostering communications between the devices. The process of creating this connection of devices is known as Computer Networking.

Technically, Computer Networking is referred to the process of transporting and exchanging data between points known as nodes, carried via a shared system, executed in an information system. The whole concept of Computer Networking does not consist only of the design, construction, and use of a network. It also involves the technical management, maintenance, and running of the involved infrastructure, software, and underlying policies.

Since the advent of wireless technologies, decades ago, our lives have never remained the same. And one thing is sure; it only promises to be better. With the gradual evolution of 5G in the mainstream, we can only imagine what is to come. One sentence does it, Wireless technology has affected the very intrinsic properties of our lives.

It has affected the way we do business; it has transformed the way we learn; it has affected the way we communicate and keep up with family and friends. Everything has changed, and this is just a testimonial of things to come.

This guide will focus on the following:

• Protocol
• Mitigating Network Threats

• Wiring Your Building
• Network Cabling
• 802.11i Robust security networks
• Subnetting
• Why Automate the Network?
• Addressing Process Risks
• IPv4 Summarization... AND MORE!!!

Introduction

A computer network is made up primarily of interconnecting common, programmable hardware. The hardware is designed for a specific purpose (for example, to transmit data or video signals). This programmable hardware can be used to transmit a variety of different types of data and can support a wide and growing range of applications.

According to this definition: (1) the hardware connected to a computer network is not limited to ordinary computers, but includes smartphones and other different types of devices like AR devices, smartwatches that are flooding the market every day (2) computer networks are not specifically designed to transmit data, but are capable of supporting a wide variety of applications (including those that may arise in the future).

We know that in the beginning, computer networks were really used to transmit data. But with the development of network technology, the application scope of a computer network is increasing, not only networks can transmit audio and video files, but also the application scope has far exceeded the general communication scope and can be perfectly used for many applications.

It is generally believed that computer network refers to the connection of multiple computers and network equipment with independent instruments in different geographical locations through communication lines (including transmission media and network equipment). A computer system for resource sharing and information transfer under the co-management and coordination of Network Operating System, network management software and network communication protocol. If you don't know what a computer network is, go home, or go to an Internet cafe, or go to your company and see for yourself. What you see is a network of pcs (personal computers) that appear to be independent and located in different places, connected by cables and boxes of devices (switches, routers).

Simply put, a computer network is a collection of computer systems, or groups of computer systems, that work independently and are connected to each other by communication lines, including connecting cables and network equipment. In this set of computer systems, resources can be shared among computers, access to each other can be carried out for a variety of computer network applications. The computers can be microcomputers, minicomputers, midsized computers, mainframes.

By sharing, I mean sharing resources. Resource sharing has many implications. It can be information sharing, software sharing, or hardware sharing. For example, there are many servers on the Internet (that is, a dedicated computer) that store a large number of valuable electronic documents (including audio and video files) that can be easily read or downloaded (for free or for a fee) by Internet users. Because of the network, these resources are as easy to use as if they were right next to the user.
