Learn Basic Knowledge and become a competent Network Administrator
After graduation, I became a network administrator in a state-owned enterprise. If the enterprise is not large, machines will be 500 ~ About 600 units; the area is not large, that is, 700 ~ About 800 square meters; there are not many buildings, that is, 6 ~ Seven. Network management is a good profession. Think about it, as long as you start to design the network well, do it well, and think well, then you will not be the one who will take the salary by the beginning of the month, instead of drinking tea and reading the newspaper every day? However, we are not as idle as you think ...... Let's talk about the knowledge required by network management.
As a network administrator, you must first know what the network is? In fact, a network is a system that uses communication devices and lines to interconnect multiple computer systems with different geographical locations and independent functions, A fully functional network software (such as network communication protocols, information exchange methods, and network operating systems) is used to implement resource sharing and information transmission in the network. The main functions of the network are as follows: one is to share hardware resources and software resources, and the other is to allow users to exchange information through this network. What we need to do for this part is to provide more and better services to users, so that users can improve their work efficiency through the network!
If you want to become a network administrator, I suggest you first learn the knowledge listed below:
1. What is the network topology? The topology is divided into bus, Star, ring, and mesh. What is the meaning of each topology? How to build it?
2. What are the basic network configuration methods for various protocols? For example, TCP/IP, AppleTALK, and other protocols.
3. Be familiar with common network products, such as servers, workstations (including terminals), switches, and firewalls. You should master the installation and debugging methods, and the maintenance at the later stage is also a required course for network management.
Now let's talk about my specific work. In general, network management has three aspects: network construction, network maintenance, and network services. For example, the initial Enterprise Network Formation (network topology structure, physical hardware selection, and network protocol selection ); then there is the construction of network resources (the establishment of enterprise post office construction, enterprise websites, enterprise FTP sites, BBS platforms, and VPN networks), or the upgrade of network hardware and software. Of course, it also includes daily network failure detection and maintenance (including hardware and software) and network security protection and management.
You can also learn from this that it is far from enough to understand some basic network knowledge if you want to be a network administrator. What is more important is the perseverance and unyielding spirit. In the face of difficulties, you must be brave enough to go forward. In addition, we have accumulated experience in solving network problems in our daily work.
A qualified network administrator's growth experience
With the rapid development of information technology, network formation has become the only way for every modern enterprise. In most small and medium-sized enterprises in China, the use of the magic tool network is still very limited, the main reason is that these enterprises lack complete management ideas and control the management capability of network administrators.
The author builds on the process of growing from a computer operator who knows nothing about the network to a Microsoft Certified Network Engineer. Based on my years of work and learning experience, I would like to share with you the growth experience of a network administrator and hope to help anyone who wants to become a network administrator.
Scope of Work
In short, the network administrator is dedicated to providing services for users of the entire network. Of course, network administrators also have different divisions of labor, which are clear in large companies and network environments, such as designing and planning networks and managing network security ...... It is very systematic and professional. To reach this level, we need to have an in-depth theoretical basis and rich practical experience as a guarantee.
However, in a relatively small network environment, network administrators are responsible for all network-related matters, such as designing and planning networks, building networks, managing servers, and purchasing network devices, it is often used as a "omnipotent person. Therefore, the challenge of doing this is very great. Whether or not we can grow depends on ourselves. If you can continue to do so, and seize the time to constantly supplement new knowledge, you can eventually reach the peak of network management and become a master of the network.
How to start
In the face of so much work, we must first sort out the priorities and priorities. The first step is to understand the operating system, because most of the time we are dealing with a variety of operating systems, such as Windows, Linux, Unix, and Mac OS. It is not enough to understand the theoretical knowledge and methods of these operating systems. We must also be able to solve the problem. This requires strong operation capabilities and clear thinking. You can go to the Internet to read articles in the discussion board and handle practical problems with more hands-on. When solving a problem, you must not only know the solution, but also learn to discover the cause of the problem.
First test knife
Next, we can start by managing a department network of about five computers to learn the basic knowledge of the network. At this time, you can attend some certification training courses and recommend MCSE certification training, it gives you a deeper understanding of the operating system and network. It should be noted that learning about nouns is only part of the required knowledge. What is important is how to use this knowledge in practice. The actual operation is very important for a network administrator.
Practice makes perfect
Next, we need to continue learning and growing in a larger network environment. A branch network of about 50 computers is suitable. Here, the number of machines increases and the network size increases. The management experience of about five computer networks is far from enough. The knowledge you have learned can be used here to a certain extent. You will begin to engage with new hardware, small network planning and design, network structure optimization, and the construction and management of new network services, and manage every computer user, and how to ensure that confidential company files are not leaked, how to ensure the security and good operation of servers, and how to implement mail communication among employees and other advanced network services are also on the agenda.
