What is a network connection?
A network connection is the ability of a device to link with other devices, regardless of their differences or similarities. In more technical terms, network connection is the transmission of data (communication) between devices via network interfaces using network protocols such as DNS and TCP/ICP.
Types of network connection
Network connections may be wired (fixed connectivity) or wireless. The difference between the two is that wired connections must have cables to support network connections, which limits their radius, while wireless connections do not.
Wired connections
Wired connections require devices to connect to the internet and other devices using physical cables. These connections typically offer more security and may offer higher bandwidth with higher speed.
- Ethernet (LAN) is a networking standard that uses physical cables to transmit data within local area networks (LANs). It increases security while also creating faster speeds and better network connections. Ethernet cable connections are ideal for businesses or individuals seeking a more secure connection.
- Fiber optics is a technology that sends data via glass or slim plastic wires that transmit information using light pulses. Fiber optics wired connectivity is ideal for businesses or individuals who want to transmit large packets of data over large distances at uber-fast speeds. It offers high-bandwidth services, making it a perfect choice for businesses, streaming, gaming, and downloading large files.
- Coaxial cables are wired connections that transmit data signals. They are commonly used for cable television or internet services.
Wireless networks (Wi-Fi)
Wireless connectivity eliminates the need for a physical network connection with cables or node networks. Wi-Fi networks use wireless communication protocols to enable greater mobility and convenience, often at a lower cost compared to wired alternatives.
- Wi-Fi (governed by the 802.11 family of standards) offers a wireless connection using a wireless router to connect devices to the internet. It also allows businesses and individuals to seamlessly connect with other devices in a low-cost, low-maintenance way. Internet connection via Wi-Fi has many factors that may affect the network’s performance.
- WPAN is a wireless personal area network that uses wireless communication like Bluetooth and has a few meters or less range. It should be used to communicate with devices close to the network connection access point. Network connections using Bluetooth or other WPAN networks are suitable for individuals who want network connectivity for a small area but are not ideal for large businesses.
- Cellular networks (4G, 5G) are a type of technology for mobile phone data connections. 5G connections are faster and offer lower latency and better speeds, which results in faster downloads and steadier streaming. 5G network connections are ideal for gamers, business owners, and those who want faster speeds, while 4G networks are suitable for many everyday tasks, such as browsing, streaming, and moderate-speed downloads.
- Satellite connections are network connections that harness the abilities of orbiting satellites to send communications wirelessly between a compact dish on Earth and an orbiting satellite. These connections are ideal for those living in remote locations or businesses outside traditional towns or cities. This type of network utilizes radio waves to transmit data from Earth to space and back again.
Factors affecting network connection performance
Network connection performance is calculated by how quickly a message may be transmitted or how fast a message can be retrieved. Several elements may affect network performance:
- Bandwidth: Slow internet speeds may be caused by low bandwidth in a network. Data packets struggle to transmit over a network because the bandwidth is limited (or insufficient for the amount of data sent).
- Latency: High latency often causes connection dropouts or a lag in video or sound quality. A network connection experiencing high latency will have more delays due to data transmitting slowly across a network. Low latency may be caused by the router location, network congestion, distance between two devices, and hardware inadequacies.
- Transmission errors: Transmission errors occur when devices attempt to communicate simultaneously. This results in colliding signals that may cause transmission failure. The more devices connected to a network, the higher the chances of collisions. Transmission errors can be caused by electromagnetic interference, damaged cables, or signal degradation.
- Network congestion: No internet access, a weak Wi-Fi signal, or devices not connecting to a network may all be signs of network congestion. This error may occur when you have a high demand for bandwidth in one network. It may also be caused by too many devices on a network, outdated hardware, inadequate bandwidth, or malicious attacks.
How to fix network connection issues
To fix common network issues, follow these troubleshooting steps:
- 1.Restart your router or modem: Always restart your router or modem. To do so, perform a complete shutdown by unplugging cables and turning off the device for more than 30 seconds. This step reboots and usually resets the systems.
- 2.Check cable connections: Examine cables connecting your device to the router or modem. Check for signs of damage on the cable.
- 3.Update firmware or drivers: Check for updates and install available updates for firmware or drivers. Updates may include network connectivity settings to enhance the experience.
- 4.Reset network settings: Reset a device's network settings to the default setting and reconfigure if necessary. Incorrect settings may be causing network connectivity issues.
- 5.Move closer to the router: A simple way to improve signal strength is to move a device closer to the router or network connection device.
Network connection security tips
Tighten network connections to reduce the risk of data interception or scammers attempting to steal your personal information. Here are the best tips to secure network connections:
- Use strong and unique passwords for Wi-Fi networks.
- Enable WPA3 network encryption.
- Disable WPS and guest networks when not in use.
- Update the name of your home Wi-Fi.
- Regularly update router firmware.
- Use firewall protection.
- Install regular software updates.
- Use a VPN for more secure connections.
