These capabilities include having to master:

Basic Hardware Network

This is where basic knowledge is sent from user to server. What types of hardware need to be used in network effectiveness are also studied here.

Basic IP and Subnetting

IP and subnetting will learn about IP efficiency and what is a gateway. This will be useful if you want to work at an ISP (internet service provider).

Technology Switching and Routing

To connect multiple networks is usually done routing on the network, so that it can be accessed from any network that is connected. You can also learn VLAN technology to master switching.

Technology server

Server technology is related to adding services needed by the client. You will have a lot to do with LDAP servers, DHCP, DNS, and others.

Security

After a good server and infrastructure are formed, then you need to pay attention to the security of servers, routers, etc.

Monitoring

Monitoring is done to control the quality of the network whether it is running properly and whether it is good or not.

Backup

This is often done by network administrators to anticipate crashes or down servers. Backup can be done differentially or fully.

We can learn these seven things anywhere. Whether on the internet, books or ebooks, or DVD tutorials.
