Computer Networking Cables: Crimping Device Tool Kits

This article explains the different crimping device tools required for connecting the computer networking cables to one another.

During the preparation of computer networking cables for creating networks like LANs, one must be extremely cautious and exact. One needs to utilize a range of wire connector assembly and installation tools to assemble and install such connectors to each other. These tool kits includes a range of cable tie guns, crimpers, cutters or scissors, pliers, punch down tools, strippers, splicers, screw driver, and cable pulling grips. These can be addressed together as crimping device tools. They all have their utilization throughout the process of computer networking. Cable tie guns are utilized to tie a heap of wires together to keep them in one place and not make a mess of wires. Cutters are utilized to cut cables. Pliers are utilized to grasp and connect wires and connectors. There are different kind of pliers available, like the circular ring, the soft jaw adjustable pliers & the connector holding pliers. Splicers are utilized to connect wires to each other. Strippers are utilized to expel the cover or insulation from the cables. A punch down device is utilized to push wires into a picked opening. Screwdrivers are utilized to loosen, tighten, embed, and expel screws from electrical connectors and assemblies.

There is range of connector types obtainable for distinctive applications. However, for electronic network cable work, the Registered Jack connectors are being utilized. The most common types being used are RJ-45 or RJ-11.

A variety of crimping tools and cable strippers are being utilized to prepare the cable for installation. The types of these tools are:

·        Cable Tie Tools - These are utilized to tighten the ties around bundles of cables and wires. They use a tension management lever to give precise tightening, while an alternate lever cuts off the ties so as to not have no loose ends.

·        RJ-45 Crimp Tools - These are utilized to crimp and cut the cables of an RJ-45 connector. These tools can also work on RJ-11 connectors as well. This tool consists of an in- built cable stripper and a wire cutter. In this manner, it cuts the wire in one go.

·        Hand Crimp Tools - These are utilized where there are sure limitations to utilizing mechanized crimp tools, particularly with respect to size, weight, and mobility. These tools can be either manual or fueled. A hand crimp tool consists of a ratchet mechanism hand tool and a pair of jaws. These tools give a method for accurate placing, supporting, and holding a cable in place during the crimping process.

·        Compression Crimp Tools - These are utilized to terminate a range of wires, compression connectors, wound pair particular attachments and jacks. These likewise have connector close heights that are absolutely built for particular connector prerequisites.

A typical computer networking cable has 8 colour coded wires that are twisted into 4 pairs. Each pair has a common colour theme. The combinations are:

   §  Blue and Blue-White

   §  Brown and Brown-White

   §  Green and Green-White

   §  Orange and Orange-White

The RJ-45 is an 8 position standard connector that appears like outsized telephone plug. While getting the connector, one should concentrate and give careful consideration as to whether the connector is made for braided or solid wire.

At the point when the connector is made for braided wires, it has contacts which really puncture the wire. At the point when the connector is made for solid wire, it has fingers that puncture the insulation and create a connection with the wire by grasping it from each side.

To make a connection for a Computer Network (LAN) cable, the cable stripper should be utilized to remove no less than 2 inches of the cable insulation sheath. At that point, the colored wires have to be compelled and arranged as indicated by a pre-determined system and cut to an equivalent length after about half or three-fourths of an inch after the cut from the insulation. Then the wires are embedded into the RJ-45 end by about a large portion of an inch and are held set up by the pleat. At that point, the RJ-45 end is crimped with the crimper tool. Be sure that the wires have wound up in the right request and reach out to the front of the RJ-45 end and reach the metal contacts in the RJ-45 end.

A cable tester can likewise be utilized to guarantee proper connectivity for the cable.

Crimping device tools and cable uncovering devices facilitate properly crimp and strip different variety of wires, like solid wire, standard wire, Teflon, PVC, neoprene, among others.

Advantages and Disadvantages of Computer Networks

Computer Networking is an essential part of any organization these days. In this article, we will be checking out the major advantages and disadvantages of Computer Networks.

"Computing is not all about computers any more. It is about living." -- Nicholas Negroponte, Founder, Massachusetts Institute of Technology's Media Lab

A computer network is defined as a set of electronically connected computers which can share information and resources among themselves. There are communication protocols that explain how this sharing should take place.

Like every other technological prospect, computer networks come with its own set of advantages and disadvantages.

               Advantages of Networks

File Sharing

The major advantage of a computer network is that is allows file sharing and remote file access. A person sitting at one workstation that is connected to a network can easily see files present on another workstation, provided he is authorized to do so. This saves him/her the hassle of carrying a storage device every time data needs to be transported from one system to another. Further, a central database means that anyone on that network can access a file and/or update it. If files are stored on a server and all of its clients share that storage capacity, then it becomes easier to make a file available to multiple users.

Resource Sharing

Resource sharing is another important benefit of a computer network. For example, if there are twelve employees in an organization, each having their own computer, they will require twelve modems and twelve printers if they want to use the resources at the same time. A computer network, on the other hand, provides a cheaper alternative by the provision of resource sharing. All the computers can be interconnected using a network, and just one modem and printer can efficiently provide the services to all twelve users.

Inexpensive Set-Up

Shared resources mean reduction in hardware costs. Shared files mean reduction in memory requirement, which indirectly means reduction in file storage expenses. A particular software can be installed only once on the server and made available across all connected computers at once. This saves the expense of buying and installing the same software as many times for as many users.

Flexible Handling

A user can log on to a computer anywhere on the network and access his files. This offers flexibility to the user as to where he should be during the course of his routine. A network also allows the network administrator to choose which user on the network has what specific permissions to handle a file. For example, the network administrator can allot different permissions to User A and User B for File XYZ. According to these permissions, User A can read and modify File XYZ, but User B cannot modify the file. The permission set for User B is read-only. This offers immense flexibility against unwarranted access to important data.

Increased Storage Capacity

Since there is more than one computer on a network which can easily share files, the issue of storage capacity gets resolved to a great extent. A standalone computer might fall short of storage memory, but when many computers are on a network, the memory of different computers can be used in such a case. One can also design a storage server on the network in order to have a huge storage capacity.

               Disadvantages of Networks

Security Concerns

One of the major drawbacks of computer networks is the security issues that are involved. If a computer is a standalone computer, physical access becomes necessary for any kind of data theft. However, if a computer is on a network, a hacker can get unauthorized access by using different tools. In case of big organizations, various network security software need to be used to prevent theft of any confidential and classified data.

Virus and Malware

If even one computer on a network gets affected by a virus, there is a possible threat for the other systems getting affected too. Viruses can spread on a network easily, because of the inter-connectivity of workstations. Moreover, multiple systems with common resources are the perfect breeding ground for viruses that multiply. Similarly, if malware gets accidentally installed on the central server, all clients in the network that are connected to that server will get affected automatically.

Lack of Robustness

If the main file server of a computer network breaks down, the entire system becomes useless. If there is a central linking server or a bridging device in the network, and it fails, the entire network will come to a standstill. In case of big networks, the file server should be a powerful computer, which often makes setting up and maintaining the system doubly expensive.

Needs An Efficient Handler

The technical skills and know-how required to operate and administer a computer network is considerably high. Any user with just the basic skills cannot do this job. Also, the responsibility that comes with such a job is high, since allotting username-passwords and permissions to users in the network are also the network administrator's duties. Similarly, network connection and configuration is also a tedious task, and cannot be done by an average user who does not have advanced knowledge of computers and/or networking.

Lack of Independence

Since most networks have a centralized server and dependent clients, the client users lack any freedom whatsoever. Centralized decision making can sometimes hinder how a client user wants to use his computer.
Computer networks have had a profound effect on the way we communicate with each other today, and have made our life easier. From the World Wide Web (www) to your local office LAN, computers have become indispensable in daily life, and networks have become a necessity in most businesses. If networks are designed and configured and having in mind its pros and cons, they are the best piece of facility you could ever have.
