Network Training

Computers are an important part of life, especially in the business community. If you work in any business situation, you may have experienced a computer network. This is the way each individual computer workstation is connected to the others. It is important that they are linked properly and can function well. A LAN (Local Area Network) is usually used for smaller businesses or larger ones where the machines are all near one another. A WAN (Wide Area Network) can be used for larger businesses. Internet and intranet systems are also available. No matter which type of network is being used, creation and maintenance of that network must be done by qualified personnel.

Network training is a great way to learn how to design, install or maintain a company’s computer network system. There are jobs in network administration with companies of all types. If you are looking for a position in a government organization, a professional office, a large corporation or even a small business, network training could be your ticket into the organization you are looking for.

A network administrator has many duties. He can be in charge of setting up the system to begin with. He would maintain the hardware and software that is utilized in the network. He would analyze problems and monitor networks for functionality. He may also be in charge of dealing with security on the network, including installing antivirus and firewall programs. They may also need to make sure that the network is meeting both the needs of the employees and the customers. This job is in high demand, and only those who have had the proper training are qualified to become network administrators.

There are a number of options for the person looking for education in the field of computer networks. Many technical colleges offer courses of study to help you become a network administrator. Universities that have computer based degrees also offer courses on computer networks. If you are not interested in the administration, you may be interested in the design of networks. No matter what part of the computer network you are interested in, it is imperative that you receive proper network training.

You can look for online courses from accredited sources and make comparisons. Remember that in order to be an administrator, you will most likely need a bachelor’s degree. If you are trying to move up in your company, you will need specialized training on the system that your company uses. No matter which way you go, you will be able to choose a program that will give you the training you need.

Computer Network Help

One of the most frustrating things that can happen to a business is when their computer network goes down and will not work. Computer networks are the lifeblood of many businesses, with the network being the connection to the rest of the office and to the rest of the world. When these networks have problems it can kill the productivity of the entire office and make life very difficult for those that are trying to get work done.

One of the best avenues for preventing the need for computer network help is installing a firewall on your computer network. Since all of the computers of a network are connected together and share programs and files, it makes it very easy for a virus to enter through one computer and quickly spread to the rest of the machines on the network. By installing a firewall and virus software on the network and all of the computers associated with it you will be able to save yourself and your company valuable time and money that would be wasted figuring out what the problem is and fixing it.

When the machines on a network do not work properly it may be cause to call a network specialist to offer computer networking help. Computer network technicians are specially trained to locate problems and find potential solutions. Many large companies actually hire full time computer network technicians to keep a close eye on their networks at all times. This may not make sense for a small business, however. A smaller company may want to outsource the work to a professional that they can call in whenever there are problems.

Since there are so many different components that make up a computer network, it is important to keep all of the different machines working properly. That means that the components of the network should be under regular maintenance to ensure that they don’t break or malfunction. The computers should be updated with the newest software updates as well as driver updates for the other parts of the network. Modems and cable connections should be checked regularly to make sure that they are not coming loose.

When your network is malfunctioning, don’t worry. Computer network help is available. All you need to do is search out for a reputable technician and they will most likely be able to get your network running in no time. When you have professional help you can get professional results.

Network Subnet Mask

A network subnet mask is needed in a network to tell the computer what part of the network address is network address and what part is host address. Network address is common to all the computers on a network, but host address is unique to each computer. It’s like a street address where every house on a street uses the same street name when addressing mail, but unique house numbers for each house.

Typical class C subnet mask is 32 bits where the first 24 bits are set to ones (or high) and the last 8 bits are set to zeros (or low). The last 8 bits are the host address part and are set to zero so the computer knows that these bits are unique to each computer. Without the subnet mask the computer would not know how to handle the IP address or how to route data.

Routers are the network devices that route data packets from network to network until the data is received by the computer that it was addressed to. The router examines the data packet using the network subnet mask to determine the destination network address. It then makes a decision on which port the send the data. The last router is the gateway router for the destination network where the host portion of the address is used to deliver the packet to the appropriate computer.

A typical network class C IP address might look like 192.168.1.0 in decimal or 1100 1010 0001 0000 in binary. The IP address when represented as a decimal number in divided in four 8-bit blocks separated by a dot. This is a type of shorthand convenience and allows us to easily convert 32 bit binary numbers as decimal 8-bit numbers. This way we only need to know 8 bit binary to decimal conversion. Otherwise a 32-bit number would be very large and cumbersome to convert.
