Job Responsibilities
As a significant part of the IT section in a company, a computer network technician has to see to it that everything from the Local Area Network (LAN) connections to the Wide Area Network
(WAN) connections run efficiently. Also referred to as a computer network engineer, such a specialist has to help plan the employer’s computer network and introduce new features to it, as and when required. Above everything else, a computer network technician requires to have precise knowledge about all the aspects of the company’s internal network since this is instrumental for information exchange. Apart from problem-solving skills, a computer network engineer needs to be adept at installation and configuration tasks.
Training and Education
Most companies search for certified computer network technicians. This means that one needs to have an advanced degree in computer networking to get through such a job. While most universities offer a Bachelor’s degree in computer networking, there are other certificate courses too that a student can make use of. In recent times, a host of online degrees have been launched to meet the educational requirements of students who seek to pursue this job profile.
IT majors like Hewlett Packard have computer networking courses that give students an in-depth idea about working on networks and keeping them up-to-date for the benefit of the employing company. However, online education would be the best option for you if you’re looking at comprehensive study of the subject.

What is a Computer Network?
A computer network refers to an interconnected group of computers. The networks may be classified according to the network layer at which they function depending upon the basic reference models. The reference models may differ from industry to industry, just like the five-layer Internet Protocol Suite model. Computer Networks are classified on the basis of various factors like scale, connection method, network relationships and protocol.
Type of Computer Networking: The common types of computer networks are:
Personal Area Network (PAN)
Local Area Network (LAN)
Campus Area Network (CAN)
Metropolitan Area Network (MAN)
Wide Area Network (WAN)
Global Area Network (GAN)
Internet work – intranet, extranet and internet
Importance of Computer Network Solutions in Organizations:
With the boom of technology and e-commerce, most of the small and large businesses today are driven by the use of internet. The Internet and the influence that it has on e-commerce and business has in more than one ways become the “great equalizer” of small business and the larger corporate giants.
Especially in the case of small business, it is very important to maintain their computer network solutions so as to keep working properly and efficiently. A whole package of computer networking solutions complete with routine maintenance, regular updates, upgrades and support can help an organization ensure that its investment is well protected and that it can survive and thrive online.
Online Computer Security Threats and Solutions
Over the years, we have grown dependent on the use of computers and related devices to conduct our daily work. It would be rare to find a thriving workplace that does not have a computer-based operation. Computers are also used heavily at home for education, work, and entertainment. People use, store, and share confidential information on their computers or on a network of computers.
The vulnerability of the data makes it essential for computer users to seek a variety of security solutions, which help them feel secure from the attack of potential hackers and third party sources. Security breaches can lead to data or financial loss for both businesses and individuals. Someone can easily access your bank or credit card details and make purchases or payments without your permission.
Without online computer security, your system will be vulnerable to virus, Trojan, worm, malware, and adware attacks. Other type of online computer security threats that you need to guard yourself against include auction fraud, spam e-mail frauds, and identity threats. The statistics related to cyber crime are startling. Studies reveal that about sixty-six percent of the cyber criminals reside in the US. But a significant number of cyber criminals also operate from Canada, China, Nigeria, South Africa, and the United Kingdom.
Internet users often end up downloading and installing dangerous viruses and malware on their system, when they visit malicious websites. This can be potentially harmful for your system. The viruses and malware can not only cause your system to malfunction, but also compromise confidential data. To protect your machine from these types of mishaps, you need to install antivirus software on your system.
Easy Fixes for Computer Network Problems
Computers are devices that bring many advantages to people. For example, students now depend on computers in making their research papers and other school related projects. Workers on the other hand depend on computers to accomplish reports and presentations needed for their job. Ottawa, like other Canadian cities, benefit from the boom of computers especially when the advent of computer networks took over.
The birth of what we know as computer networks now was inspired by the earlier version of the ARPANET. This early form of network between various research institutes in the US revolutionized the way people get in touch with each other. This new network signified a new phase in communications that far outweighed the telephone. Network communications allowed people virtual conversations without the need to worry about charges.
Today, computer networks are widespread and are no longer limited to research institutes. Corporations, small businesses and even homes may be using computer networks to effectively manage programs on their system or simply as a means to communicate with each other. Of course, a computer network is not without problems, major cities may experience a breakdown at one point so it may be best to know the following steps:
Determine the cause of the problem before calling for help. In cities like Ottawa, computer network support issues maybe minor ones so you can try steps like rebooting the computer and unplugging and plugging back the computer network wire. You can also try clicking ‘My Network Places’ in your PC to see the speed of your LAN connection. If the speed remains very slow despite the efforts you made then it’s time to contact technical help.
Whereabouts Of Computer Networking Devices
Computer network equipments are also known as computer network devices. This computer network is encompassed with various different devices to share various elements such as data, applications, voice and transmit and other communication links to other networks and files. The equipments are the physical parts that are directly connected to the computer to get the network.
Day by day, with the growth in technology, the network working devices are also increasing and hence, there are numerous means and devices to get a computer network. The most common devices amongst them are individual computers, server, hub, switch, bridges, routers, modems, printers, gateways, network interface cards, cabling and wireless access point and many more. Hence, networking is full of computer networking equipments which is the most popular computer network equipment used at present and hence is discussed in more detail below.
Routers: Routers are one of the most important pieces of equipment in the area of computer networking. Routers are there to determine the destination address for the data in the best way with the help of their software called routing software. Routers are there to make sure the data communication between the computer and the net runs smoothly and correctly without interruption. Thus, routers are known to route and forward the networking information from one destination to another destination.
