Load O Computer Networking

In todays world many companies have their own local Secured! computer networks.  Most companies use the star network configuration for ease of use and lazy computer networks engineers.

An avarage size company will have about 200+ computer stations in their local network attached in a star configuration to one server and this one server is usually attached to the internet to give all the users their gateway to heaven, or maybe not ?

You know that hardware and software firewalls all have been hacked and penetrated by unemployed excellent programmers and engineers.  No one is safe anymore from getting loads of viruses through the internet.  One virus through the server can turn the internet gateway to heaven into hell.

This virus threat is not restricted to internet and does not only penetrate large computer networks for fun, but it also feeds on home and personal computers that open wide to receive loads of infections and viruses.  Those homes might be your employees ?

Most companies started using Network Monitoring Software to keep their network safe from internet threats and local internal threats.  This software usually costs way too much without much in return.

Some companies take the other route to buy Employee Monitoring Software that will monitor their every move and turn their moral really low.  USB Security Software might be a good solution to give your employees Freedom and at the same time give them full control and responsibility of their USB Drives.

How ?  Large computer networks should have a USB Monitoring PC installed as an entry test point for all USB Drives entering the facility, in a couple of seconds the USB Drive Monitor can log all folders and files on a USB Drive up to 3 folder levels deep.  Not only that, it can also record the time in seconds, name of the USB Drive, the size of the USB Drive and most importantly is the Unique Hardware Key for that specific USB Device.

Using the USB Drive Monitor will allow each employee to block USB ports for USB Mass Storage Devices except for their own Personal USB Drive that is known and identifiable at the Entry Test Point PC.  Now the employee have the capability to only use their own USB Drive with full responsibility and total freedom.  The USB Lock Software functionality that is provided by the USB Drive Monitor will allow them to easily lock and unlock their PC with their Personal USB Drive in a snap.

This way every employee will have the task of securing their own computers from Foreign USB Drives and at least and the Entry Test Point can log and identify files and USB Drives that might have problems before getting into the computer network.

USB Lock and USB block are only some of the features offered by the USB Drive Monitor.  You can download the USB Security Software and try it with the help of our support page, you can get to know the power of this software and customize it to your needs in minutes.

Being wait-listed is tough, and you need the right set of keys to open the door to your dream program. The truth is that even with these keys, it’s still not guaranteed that the lock will work. But this keychain has the critical pieces of metal you’ll need to turn that lock.
First, a word of introduction: Realize that receiving a wait-list letter means you qualify for admission. You pass. You are probably on the wait-list (and not admitted) because they have already admitted applicants with your profile and want diversity in the class. Or they find your qualifications impressive, but find someone else’s even more so.
Now let’s examine that keychain. has become an essential prerequisite for any efficient modern-day business as it allows employees to truly work as a team by sharing information, accessing the same database and staying in touch constantly. For a computer network to give the best results, a lot of detailed planning and foresight is required before installation.

Firstly, an organisation needs to clearly define its requirements – how many people would use the network, how many would use it locally (within the office) and how many might require remote access (from a different location), how many computers and other devices (servers, printers, scanners) would be connected to the network, what are the needs of the various departments and who would be in charge of running/managing the network. It also helps if one can anticipate the direction the company would take in the near future so potential growth can be factored in during computer network installation.

The technology issues should also be ironed out in advance – hardware, software, servers, switches, back-up devices, cables and network operating systems. Make sure you have the required licenses to run the software on all your machines before installing a computer network. Alongside computer network installation should proceed ,the building of a dedicated technical support staff, either within your own organisation or outside consultants. Delegate responsibility clearly for network management. Before installing the network, you also need to choose the security mechanism to protect corporate data and keep viruses at bay.

The transition to a new or upgraded computer network can bring some teething problems. To minimise chances of confusion, the company might need to train its staff to make them familiar with the new system. Careful planning will to a large extent prevent crises like system downtime and network crashes.

Accepting all the benefits that a computer has provided to facilitate a man, the hazards due to malfunctioning of the computers bring headache along with it. Consulting the IT experts for computer support is another thing that carries worries because who to trust is a big question.  Reliability demand is necessary to consider when you visit an IT repair shop. Whether for individual needs or group needs, IT support services play a crucial role in smooth running of the systems.

Computer networks are established in a company for various purposes like for communication, record keeping, tracking workflow and the last but not the least is the maximizing of the profits by increasing productivity. It has shared the burden of the physical work. True to the word of machine revolution. Network support is also needed to multiply the benefits.

The timing of getting out of order and correcting the disorder doesn’t match in most of the cases. Several companies are there in the market to show their skills and expertise. They too are doing business. A good company that provides the business IT Support to the computer networks is the one that knows those bad timings and can well imagine the unpredictability of these technologies. 24/7 services are always preferred and welcomed in order to provide repairing services to the computers setups in any company because the business timings are getting beyond limits with the growing global concept of economy. And if you have to wait many days for your computer networks to return to fast track then you can imagine how much loss you have to bear. How much work would go pending? He knows who bears.

The easiest and the most convenient way to provide 24/7 IT support services is the online mode. The IT companies that are contracted for their services are responsible to identify your individual business needs and the provision of services according to those needs. Whenever your system suffers any problem the online support system is there to your help. Just let them know they will work to the best possible way. Online computer support service providers have IT engineers, skilled teams that are experienced in their fields. They will guide you what to do with the problem. Telephonic support is also provided if the need arises. Another big benefit behind online support service acquisition is the time and the cost factor. You can save your time instead of wasting it on shifting from one IT repair company to another but not getting the satisfactory results. Some online service providers don’t charge a single penny unless you get your system corrected. It saves your money.

Rely on technology, it will give you the best but searching for the best one should be your concern. Every online network support service provider can’t be trustworthy. Search cleverly, pay smartly and get support professionally. You will surely be benefitted.

The sharing of fax machines, printers, and modems amongst many computers and users reduce the operational cost. A database on a computer network is a very important application as it stores and runs many important data and jobs. Emails and chats can be used for instantaneous communication and sending of files on a computer network.

The computer networks are classified, depending upon the size, as Local Area Networks (LAN), Wide Area Networks (WAN), Metropolitan Area Networks (MAN) and Personal Area Networks (PAN). The topology (topology is the way the computer networks and network resources are connected) of the networking can be classified as Bus Network, Ring Network and Star Network.

The networking hardware basically consists of wiring, network cards and a hub. Computer network cards are required so that one computer can understand what the other computer is “talking”. Network cards have a unique MAC address to identify computers on a computer network. Hubs connect all the computers in the network. Hubs can also be used to connect to other hubs to increase the size of the computer network. Two computers can be connected using Ethernet cards or phone lines or power lines for communication, with hardware kits available at roughly a cost of $100.

As the number of computers in an office or a home increases, so do the number of cables, so wireless networking is a viable solution. In wireless networking radio transreceivers or infrared signals are used to communicate between computers and devices. Examples of wireless networking include Wi-fi and Bluetooth technology, though there may be security issues involved in wireless networking. However there definitely is a stronger preference towards wireless networking nowadays among consumers.

Computer networks have added a new dimension to the 21st century. Today the cyber world is much faster and wider than the real world. This has all been made possible due to computer networks. Computer networks have revolutionized business, communication, travel, research, defense, society and almost all human endeavors. The evolution of computer networks has helped the technological revolution take a big leap forward.

Modern lifestyles means that everyone in the home, from about 5 years of age to 85, is busy leading their own lives. There is less time for the old fashioned family get together and meetings. But most families do manage to keep abreast of what is happening in the lives of other family members, if not by a great deal of personal interaction, them at least online. In growing numbers, home computer networks are where families catch up with each other. And of course, interact with the outside world.

That is why when something goes wrong, the whole family is upset. One computer not working is tough, but other ones can be used. But when the network goes down, everyone is affected. There is no backup. The only thing to do is call in a technician to get the home computer network repair done ASAP. But before you embark on that course, there are some basic home computer network repair precautions you need to take.

Home Computer Network Repair Precautions

One of the most obvious things is to be sure of the competence of the people you call in. You need to check not just on their qualifications and experience, but also get some references from them and check these out. Getting a simple home computer network repair done by people not competent to do the job can lead to a major home computer network repair issue later on.

Find out what caused the problem. It may be due to non computer factors like an electrical short circuit, dampness in the walls affecting the wiring, a faulty switch board causing power surges and so on. Get these problems repaired before you start the home computer network repair started so the hassles do not keep reoccurring.

If any hardware is being replaced, make sure that it is original – from the manufacturer. Often those doing in home computer repair promote parts that offer them the largest commissions. These may be okay, but why take a risk?

If it is a software problem, try as far as possible to reload the software from the back up disks that came with the hardware, or download from the manufacturer’s website. Be very careful of installing technician recommended software you are not sure of.

If it is a virus related software problem, make sure that you install the latest anti virus software before you use the network again. Otherwise your home computer network repair could become a regular feature of your lives. And finally, what kind of guarantee are you getting on the home computer network repair? This varies, but 3 to 6 months is reasonable.

Most home owners are not computer experts – they use the network like any other piece of domestic equipment. But a home network is a complex amalgam of hardware and software and getting your home computer network repair done by people who are not experts in both could mean facing repeated problems.

The Information Technologies sector has quickly become one of the largest industries in the business world. Computer programming and network configuration are two of the most popular jobs among college graduates presently, and with good reason. In the last decade, technology has advanced in leaps and bounds, which means that any business will only really benefit from implementing and understanding the latest technologies.

A computer network can only help a business’ bottom line as it reduces, or may even eliminate altogether, latency, increases efficiency and keeps the business connected. A computer network installation requires plenty of planning and foresight, but it is well worth it in the long run. However, the computer network cannot be simply set up and left alone, which is where computer network training comes into the picture.

If a business is to use a computer network, there needs to be a considerable amount of organization involved. Part of computer network training and preparation is to determine how many people will be using the network, how it will be used and the number of people that will use it locally (in the office) and remotely (offsite). It is also important to know how many computers and devices, including peripherals like printers, scanners and servers, will be required for the network in question.

Before there is any consistent computer network training, technology issues and requirements should be discussed. Obviously there will be computers, but what else? Plan out and discuss what is needed in the way of hardware, software, switches, servers, back-up devices, network operating systems and even things as simple as cables. Part of computer network training also involves the preparation and consideration of any required licenses, responsibility requirements, and security measures.

If there is an existing network in place, the technology department (IT Department and network operators) should regularly train on all of its aspects. Regular review sessions should be scheduled, perhaps along with consistent security reviews of the system. If a new computer network is implemented, there should always be sufficient training so that staff can make the transition smoothly.

There is a multitude of ways that staff can undergo computer network training. If the business employs in-house IT staff, an employee specialising in computer network programming may be in charge of keeping everyone informed. There are also classroom opportunities or seminars where an instructor may visit the office to train the staff. Additionally, there is computer based training (CBT) and web based training (WBT) that are very similar to their CD and DVD counterparts. Furthermore, there is no shortage of books and other reference materials.

Regardless of the method chosen for computer network training, it is an essential part of a successful business. Many companies integrate large, intricate networks and must take into account the tightening data protection laws and security measures. Having a staff that is well-versed in computer network issues ranging from design, planning, implementation, security precautions and maintenance, can only help to ensure the overall efficiency, productivity and success of a business.

A computer network is a collection of two or more computers with communication between them through a medium. The communication medium can be through radio waves, wires, infrared, optical fibers etc.

Computer network is an integral part of our daily lives, with the most important reason being that of communication. The use of computer networking is to share resources like fax machines, printers, modems, files etc. , and its other uses are database server, computer server, email, chat, internet etc. The computer to which the resources are attached is called the server and the other computers that access the resource are called clients. In peer-to-peer computer networks there are no servers.

The sharing of fax machines, printers, and modems amongst many computers and users reduce the operational cost. A database on a computer network is a very important application as it stores and runs many important data and jobs. Emails and chats can be used for instantaneous communication and sending of files on a computer network.

We know that  interconnection between computers  are essential for the proper working of a big organisations. Computers are interconnected inorder to share the informations between them. . Here iam going to simply describe the necessity of computer networks , advantages of networks and methods of interconnecting computers.

                                         How to copy informations in a computer to another?? We can use a CD , pendrive etc. . But is these methods possible for massive transactions of data??

NO…NO. For that, there comes the networking of computers. Exchange of informations between computers is essential in offices, bank,research centers etc. . Connecting computers together so as to exchange informations easily and rapidly is called Networking.

                            ADVANTAGES OF NETWORKS

A)               Resource sharing     

                 Many of the peripherals used along with a computer are costly. When we connect uses many computers, we have to connect many peripherals. This  expense is very large . This problem is solved by networking. Suppose there is only printer with computer A. If we want to print the data from a computer B, which is interconnected with computer A. When we give print command to computer B, it sends the print command along with the data to computer A. Thus we get print through computer A.

                                          We can connect  one computer to internet through telephone line and connect other computers through network,share internet services available in the computer having internet connection.

B)               Centrally Controlled Informations

                     For  some computers under network,there is no need to copy a data to all computers. Just copy the data in one computer and it can be accessible from other computers in the network. But some of the data may be of confidential in nature. It cannot be allowed to others to access that data. Some control methods have to be adopted. There should be  a facility to decide what information is accessible by whom and what kinds of access  rights can be provided. A person is made responsible to arrange and control the computers in a network in this manner.

C)               Security of Information

                The informations stored in computers may be lost due to machine failure, virus infections etc…Imagine that  a situation  of losing datas of a bank!!!!!! This kind of important informations can be copied to other computers through network. If the informations stored in a computer is lost, the copy stored in other computers will be safe. The network is utilized by defence institutions, bank,software development companies, research institutions etc in this manner.

D)                   Media For Communication

                 There are different ways to utilize network as communication media. WWW, E-mail,video conferencing etc are some of the examples. As a media, main advantage of networking is that we can share audio,video,pictures etc

                     TYPES OF NETWORKS

Let’s look what are the different types of network, how they can be implemented etc

If the distance between two computers is short, the network is called LAN(Local Area Network) The network within a room , a building or an organisation come under the category of LAN

                  The network constituted by connecting computers at distant areas is called WAN ( Wide Area Network). the computers  at thousands of kilometer away from each other can be member of WAN. They use satellites or optical fibre for information exchange…

                   HOW COMPUTERS ARE CONNECTED?????

      We know that informations are transferred between computers in the form of bits. There are many media used to transmit such bits. . The following are some of the transmission media. .

A)    Coaxial Cables

         Computer networks can be materialized using coaxial cables. The informations are transmitted in the form of electric signals through this cable.

B)     U. T. P Cables

Un-shielded Twisted Pair Cable is a set of twisted paired wires. They are largely used to design small networks. They also transmit informations in the form of electric pulses….

C)    Fibre Optic Cables

Informations are transmitted in the form of light rays in the fibre optic cables. These cables can transform large amount of data at a high speed. They are used for constructing large networks.

D)    Infrared Rays

Infrared rays are electromagnetic rays with frequency larger than red light. If the distance between the computers is very short, it can be used. But there should not be any obstruction between computers. The advantage of this is there is no need of cables. This medium is not using today.

E)     Radio Waves

When radio waves are used as the medium, obstructions are less affected to data transfer than infrared. . In addition radio waves are better for networking computer situated far apart.

               NETWORK INTERFACE CARDS

                 If a computer is to be attached to the network, a special circuit board is to be fixed in to the computer. It is the circuit board helps our computer to communicate with other computers through the network media. . This is called network interface card. The cable used for networking are connected in to this card.

                       NETWORK PROTOCOLS

                 All computers in a network need not be same type. Hence the computers in the network should follow certain rules and regulations for proper exchange of informations. . These rules are called network protocols. Today widely used protocol is TCP/IP.

                                 IP ADRESS

 Each computer in a network has its own address. If the computer belongs to TCO/IP, the address is called IP address. Computers are identified using these addresses for sending and receiving informations.

Here I just mentioned about basic concepts of computer networking.
