Voltage is the pressure from an electrical source that pushes electrons through a conductor to create current. It is measured in volts and represented by the letter V or E. The standard unit for voltage is the Volt (symbol: V and a symbol: E). Voltage can be either Direct Current (DC) or Alternating Current (AC). A battery produces a DC voltage, while home outlets produce an AC voltage. The most common household voltage in North America is 120 volts AC, while in Europe, it is 240 volts AC. Voltage can be increased or decreased with a transformer. Voltage is crucial in daily life as it powers electronic devices such as… Read More

VoIP, or Voice over Internet Protocol, is a type of communication that allows users to make voice calls using a broadband internet connection instead of a traditional phone line. VoIP has many advantages over traditional phone service, including lower costs, increased flexibility, and enhanced features. One of the most significant advantages of VoIP is that it can be much cheaper than traditional phone service. This is because VoIP uses your existing broadband internet connection instead of requiring you to purchase an additional phone line. Additionally, VoIP often comes with various features that are either unavailable or cost extra with traditional phone service. For example, many VoIP providers offer call forwarding,… Read More

A Virtual Local Area Network (VLAN) is a logical grouping of network devices that share the same broadcast domain. A VLAN can span multiple physical LANs, and it allows for the segmentation of a network into logical subnets. Each VLAN has its own unique identifier (ID), which is used to distinguish one VLAN from another. VLANs are created in order to improve network performance and security. By creating separate broadcast domains, traffic on one VLAN does not need to be forwarded to all other devices on the network – this reduces overall traffic and improves performance. In addition, by isolating devices into different VLANS, it becomes more difficult for unauthorized… Read More

A VPN, or Virtual Private Network, is a tool that allows you to create a secure connection to another network over the Internet. VPNs are often used by businesses to allow remote workers to securely connect to the company network. They can also be used to encrypt traffic between your computer and a website, making it harder for anyone on the same network as you – like your ISP or government – from snooping on your activity. There are many different types of VPNs, and choosing the right one depends on your needs. If security is your main concern, look for a VPN that offers military grade encryption. If you… Read More
