Additionally, they are responsible for any problems that may occur on the network and must resolve them as quickly as possible. Users experiencing network access issues can turn to this professional working within the IT department for assistance.

How much does a Network Administrator charge

The average daily rate for a network administrator amounts to £400. The salary of a network administrator amounts to, on average, £30K per year.

What is the definition of a Network Administrator

A network administrator is a professional in the IT sector who will handle the implementation and maintenance of the computer network within a company. Their goal will be to ensure that the technologies used are optimal. They must handle the installation of new devices, but also manage network access for users.

What type of mission can a Network Administrator handle

A network administrator will mainly have four major activities. Generally, they will handle the implementation as well as the management of a company's computer network. They will then need to acquire hardware, software and ensure their proper installation. They will also be in charge of network administration, which means they will manage security standards as well as access to different networks. They will occasionally focus on the network operating budget, as well as network performance monitoring dashboards. The network administrator's goal will be to help users who encounter problems on the network or on workstations. They will intervene in case of failure, and this, as quickly as possible to allow users to access data present on the network. Finally, they must be able to perform technology watch to anticipate any modifications needed on the network so that it remains operational and efficient.

What are the main skills of a Network Administrator

A network administrator has many skills and is notably considered an expert when it comes to network and system administration. A company's computer system holds no secrets from them and they know communication protocols perfectly. Regarding communication technologies, they master most of them to enable their proper installation within the company's premises. With Windows and Unix being the main operating systems, a network administrator must know them well. Such a professional, whether working freelance or not, must master technical English to best manage the implementation of the network within the company.

What is the ideal profile for a Network Administrator

There is no typical profile for a network administrator, but they must still possess certain qualities. They must, for example, be able to listen and communicate easily with others, as users may come to them for various clarifications. It is imperative to be attentive and responsive, since this profession requires managing sometimes up to several hundred computer workstations. Moreover, in case of technical failure, a network administrator must know how to keep calm in order to resolve various problems as quickly as possible. It is also noted that patience and curiosity are two important qualities insofar as some problems may take time to be resolved. It also remains necessary to be curious since technologies evolve rapidly, a network administrator must be able to update the network or order new equipment as quickly as possible. The ability to quickly understand how new technologies work is also not negligible.
