Hardware networking tools are the physical services used to set-up, maintain and troubleshoot computer networks. The tools are particularly relevant in the installation of wired networks where Ethernet cables are involved. They are used by network technicians and engineers to establish appropriate connections of cables, perform testing of network lines, and establish a sure communication between devices like computers, routers, switches, etc.
In the construction of a Local Area Network (LAN) one would have to prepare cables in a manner that would enable the flow of data without failure. Hardware networking devices assist technicians to cut, connect and test cables correctly. The most popular hardware networking devices are the RJ45 connector and crimping tools as well as LAN testers. These are necessary to design and support Ethernet cable connections.

RJ45 Connector
One of the most significant components utilized in the Ethernet networking is the RJ45 connector. RJ45 is the abbreviation of Registered Jack 45 and it is the standard connector that is used in attaching the Ethernet cable to the networking gadgets like computers, routers, switches and modems.
RJ45 connector is a small plastic connector that fits on the extremes of the Ethernet cables which can be either Cat5, Cat5e, Cat6 or Cat7. The connector has eight small metal pins consisting of which are connected with the eight wires within the cable. Such pins enable communication of data between devices in the network.
The RJ45 connector is an Ethernet connector that is compatible with networking equipment ports. The connector is placed and when it is inserted in the port, there is a small clip which holds the connector in place, making sure that it connects. This is a way of eliminating unintentional disconnection during the operation of the network.
Reasons why RJ45 connectors are very popular are that, they can allow fast data transfer and can be used with most of the current day networking devices. The connector must however be fitted correctly so as to make sure that the wires are fitted correctly. Poor wiring will lead to network downtime or to a sluggish network.

Crimping Tool
Crimping tool is a hardware tool that is used to securely connect the RJ45 connectors to Ethernet cables. This is a tool that is necessary to network technicians when they are required to make network cables of custom lengths.
The crimping device functions by stamping a metal connector of the RJ45 connector into Ethernet cable wires. When the technician inserts the connector and the cable into the crimping tool and clicks on the handles, it forces the pin into the wire. This is done to ensure that the wires are fixed and a good electrical connection is provided.
There are other features in most of the crimping tools. It has a built in wire cutter that lets the technician cut the cables to the size he/she wants. They might also have a wire stripper that assists in removing the outer insulation of the cable to enable the internal wires to be connected and fitted in the RJ45 connector.
The proper installation of a crimping tool is important in installation of a network. The Ethernet cable has to have internal wires which are designed to fit a particular color scheme, typically the T568A or T568B standard of wiring. After throwing the wires into the right order they are pushed into the RJ45 connector and crimped with the tool.
When crimping, it is important to have a proper crimping so that the cable can offer a stable and reliable connection between the network devices.

LAN Tester
A network cable tester or a LAN tester is a hardware device that is used to test a network cable, to determine whether it is functional or not. Once RJ45 connectors are attached to the two ends of an Ethernet cable, a LAN tester is used by the technicians to ensure the cable is wired properly.
A LAN tester is generally divided into two components; a main unit and a remote unit. The Ethernet cable is attached to one end of the main unit and the other end to the remote unit. Upon activation of the tester, the tester transmits signals along the cable to verify every connection of wires.
tester shows the results as LED lights or digital display. its indicate the whether all the wires within the cable are connected properly. The tester will determine the problem in case there is a broken line, crossed line, or short.
LAN testers prove to be very helpful as they enable the technicians to identify the wiring problems within a short period of time. In the absence of testing, one would not find out whether a network problem was a result of the broken cables or other network parts.
Technicians can also be certain that Ethernet cables are good when it comes to the passage of information as well as network performance through a LAN tester.

Significance of Hardware Networking tools.
The hardware networking tools are very essential in network installation and maintenance. They enable the technicians to create a network cable that is custom made, connect the devices accordingly, and make tests on network connections.
Accuracy is one of the key advantages of such tools. Crimpers and LAN testers are some of the tools that can be used to ensure that the cables are correctly assembled to minimize the possibility of the network going out.
Efficiency is also an added benefit. By having proper equipment, the network technicians are able to install and repair the cables within a short time hence they save time in setting up and troubleshooting a network.
Network reliability is also maintained with the help of these tools. Correct and proper connection of cables and their corresponding testing is what makes sure that the data flows between devices in a smooth environment, which is crucial in maintaining consistent network operation.
