Networking Tips to Remember

Networking Tips to Remember

Computer networks are used to share the data and resources and for the communications. To get the optimized performance, data protection, maintenance, improved reliability and the security, every system administrator and network administrator should know the basic maintenance, troubleshooting and security techniques. Downtime is very dangerous for the critical network business applications and servers.

Here is a list of the things you should know before setting up your very own computer network that you have to manage and maintain yourself:

  • If you want to connect more than two computers you will need either a switch or a router. The router or switch basically acts like a splitter that allows internet access to all computers that are connected to it using an Ethernet cable.
  • Use the configuration wizard that comes with your router when setting up the network for the first time and remember to only connect one computer at first in order to set the router and to test the functionality.
  • Most routers can be used out of the box without any kind of trouble, unless you are using a PPPoE connection or any other type of connection that requires a password or other personal information in order to function properly. So I suggest plugging the computer in and seeing if that works.
  • Always make sure that you use security programs such as antivirus and firewalls. They will protect from 99 percent of threats and save you a lot of time and a lot of trouble.
  • If you have a private network that needs no connection to the internet, go for a switch instead of a router.
  • Make sure you use a firewall (hardware) in case of corporate networks.
  • If you have proxy servers, use a L3 switch instead of a router because it will be more flexible.
  • Make use of a WAN optimization device so that you can save the bandwidth.
  • While setting up your computer network, make sure that cabling is proper and the length of the cable is optimal.
  • Buy managed switch if possible if you are not very much experienced in setting up a network.
  • Decide on wired or wireless network based on the requirements.
  • Make security your utmost priority in case of corporate networks.
  • Plan the network beforehand and only implement the computer network after you consult with experts.
  • Never use a hub even if one is available.
  • Buy trusted hardware for your routing, security and switching needs. CISCO, CheckPoint, Juniper etc are trusted brands.
  • Use a DMZ (Demilitarized zone) in case of external access requirements and also recommend allowing a professional to setup your network if you can’t handle it yourself. Some people are not inclined towards this type of knowledge and it would be a waste of time trying to make it work on your own. You can even ask a friend that has done this before. This way you are also going to learn to do it yourself the next time around.

In the modern world you really only need a couple of computer networking tips if you plan on establishing a network in your home. Most of the times it is straight forward and will require minimum input on your behalf.
