Network and Internet
What Is a Network?
Network is a computer network connected to the devices to share data and access services. It takes place on the printer, file server or internet of computers in the office. What is a Network is the first step to understand the question, distinguish the connection problems correctly and plan the network infrastructure that suits the business.
What does Network components work?
The switch provides communication of devices in the same local network. Router determines the direction of packages between different networks. Access point adds wireless access to wired network. The firewall checks the traffic according to defined policies. These functions can be combined in one device but are technically different.
The cables are part of the network of connection panels and energy supply of devices. Well-configured devices can not eliminate the problem formed by a incorrectly terminated cable. The logical structure with physical infrastructure should be discussed together.
Difference between LAN and WAN
LAN expresses local network in a restricted area, such as office or building. WAN connects networks in different locations; The internet is a wide example of it. Access to the application in the center of branches gives different connection, routing and security requirements from the local network.
VLAN can create logical network separation on physical infrastructure. It is an example to separate guest devices from business computers. VLAN does not interfere with all access per single; Rules and redirect between networks should also be defined.
How to plan a office network?
- Number user, printer, phone, camera and wireless devices.
- Set the speed, delay and access requirements of applications.
- Check the cable brackets and wireless coverage.
- Document IP address plan and network discrimination.
- Limit management access; backup device configurations.
- Evaluate growth, energy and connection failure scenarios.
How to split the internet issue with network problem?
Check if the problem affects all of its office. If external sites are not opened when they are trying to access the local file server, the internet output or DNS may be examined. Wired connection is uniform, wireless connection is problematic if the coverage and channel density stand out.
Error time, affected devices and recent changes must be recorded before the devices start randomly. These records make it easier to find the source of repeating problems. Network map and label wiring make it visible to which component will be controlled during failure.
Frequently Asked Questions
What is the same internet with Network?
No. A local network may also share files or printers without connected to the internet. The Internet is a wide structure connected to different networks.
Does the switch improve internet speed?
Not only increase the subscription speed per single. Fix unstable or defective local network connection can ensure better use of existing capacity.
Is it completely replaces the wireless network wired network?
It depends on the need. Wired access on devices using fixed and intensive traffic can be suitable for wireless access on mobile devices.
