Over a period of time, computers have become an indispensable part of businesses. Installation of computers, their support and maintenance are services all organizations require. As businesses grow, the number of computers in the organization also increase. It becomes imperative to establish a systematic way to connect these computers so that they function in a hassle-free manner. Therefore, computers are interconnected in various ways. This is the concept of a computer network.
What is a computer network?
A computer network can be understood as a number of computers connected together to share resources. The most common resource shared is the internet. Other resources can be printers, file servers, etc. The computers in the network may be connected through an Ethernet cable or wirelessly through radio waves.
Now we will see how the individual computers in a network are connected:
Computers connected in a network are referred to as nodes.
Star Topology:
In this case, there is a central node from which connections are provided to individual computers. In this case, even if there is any problem with a particular cable, the other computers can continue to function undisturbed. On the flipside, this type of connection requires a lot of cabling.
Bus Topology:
In this case, all the computers are connected by a single cable. The information that is intended for the last computer needs to travel through all the nodes. The chief benefit is that it requires minimal cabling. However, if there is any fault in the cable, all the computers are affected.
Ring Topology:
In this topology, all the computers are connected through a single cable. The end nodes are also connected to each other. The signal circulates through the network to reach the intended recipient. In case, a network node is configured incorrectly or there is some other issue, the signal will make numerous attempts to find the intended recipient.
Collapsed Ring Topology:
In this case, the central node is a network device known as the hub, router or switch. This device runs in a ring featuring plugins for cables. And, each computer is independently connected to the device through individual cables.
Each organization chooses its own topology of the computer network to ensure a streamlined functioning of their computers. Once the computers are connected, offices also have separate cabling closets, which is essentially a space containing a switch device that connects to the network.
There are a number of computer network companies that provide the services of installation, maintenance, and support services ensuring smooth and streamlined functioning of your systems.
Computer networking has become an integral part of everyday life. Networks are used by multitudes of people from the businessmen that share information with each other to the teenager uploading photos to a social networking site. The role of online education in computer networking is to teach students to keep networks working and usable. Education is obtainable from numerous online universities that offer several concentrations.
The connection between computers that share information defines the industry of computer networking. This is a complex system that needs the constant work of specialists. Online training encompasses many aspects of the field, which includes network design, troubleshooting, maintenance, and information protection. Based on career trends, having an education is quickly becoming a standard due to continually advancing technology. Students learn how to be specialists that provide daily support, train individuals to use a system, and develop a network for a company. These are only a few areas that are covered through courses in a program.
Education is available through concentrations that include:
Computer Network Engineering
Computer Network Management
Network Support
Network SystemsEach available training option provides students with the knowledge needed to carry out specific functions. Online colleges give students the ability to work through programs at the associate's, bachelor's, and master's degree level. Graduate level training at the master's degree is not a career requirement but students will fare better in their career with the advanced knowledge gained. Earning an associate's or bachelor's degree is the educational standard for the industry's professionals.
Problem solving is one of the main roles of a computer networking professional. Students that participate in an online program in network support will gain the necessary skills for this function. Specific coursework explores how to create, design, install, manage, and fix a network when it stops working or needs updated software. Online courses help students develop their computer, technology, and management skills. Subjects on computer programming, data security, and software integration are a few topics discussed inside a program.
Computer network management programs are another area available that teaches students a core role of the industry. Students learn the process of configuring, establishing, and managing a system of networks. The software and hardware of the industry is evaluated from a management standpoint. Students learn to oversee and maintain local area networks and wide area networks. Network security, remote access, data communication, and computer architecture are some online courses students can expect to complete as a regular part of education.
The available programs prepare students to enter a career as a computer networking specialist. An accredited online education in each concentration area gives students a foundational knowledge of the field while building a particular set of skills. Full accreditation is provided by agencies like the Accreditation Commission of Career Schools and Colleges of Technology (http://www.accsc.org) to programs that meet certain criteria and offer a quality education. Students can utilize the accessibility of the Internet to research the correct program and online college for their objectives. Find a program and beginning training.
