What is Wide Area Network Glossary?
This section introduces fundamental terms you'll encounter when discussing or working with Wide Area Networks (WANs). Understanding this Wide Area Network Glossary is crucial for anyone involved in IT, telecommunications, or network administration. These terms form the building blocks of network vocabulary and will help you articulate complex ideas more clearly. Grasping these will also aid in understanding network jargon more effectively.
| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| WAN (Wide Area Network) | Noun | A network that connects computers and devices over a large geographical area, like cities or countries. | Our company uses a WAN to connect its offices in New York, London, and Tokyo. |
| Router | Noun | A device that forwards data packets between computer networks, essentially directing internet traffic. | The router directs traffic between our local network and the internet. |
| Bandwidth | Noun | The maximum rate of data transfer across a given network path, often measured in bits per second. | We need more bandwidth to support our increasing video conferencing needs and avoid slow connections. |
| Latency | Noun | The delay before a transfer of data begins following an instruction; a measure of time delay in communication. | High latency can make online gaming very frustrating and cause lag in video calls. |
| Firewall | Noun | A network security system that monitors and controls incoming and outgoing network traffic based on security rules. | A firewall helps protect our network from unauthorized access and malicious software. |
| VPN (Virtual Private Network) | Noun | A secure, encrypted connection over a public network (like the internet) to a private network. | Employees use a VPN to securely access company resources when working from home. |
| Protocol | Noun | A set of rules governing the exchange or transmission of data between devices. Read more about protocols. | TCP/IP is a common protocol suite used for internet communication. |
| ISP (Internet Service Provider) | Noun | A company that provides customers with internet access. | We chose a new ISP for faster internet speeds and better reliability. |
| Cloud Computing | Noun | Delivering computing services (servers, storage, databases, networking) over the Internet (“the cloud”). | Many businesses are moving their data storage to cloud computing services for scalability and cost-efficiency. |
| Node | Noun | Any device connected to a network, such as a computer, printer, server, or router. | Each computer in the office is a node on the local area network, capable of communicating with others. |
| Packet | Noun | A small unit of data into which a larger body of data is broken down for transmission over a network. | Data is broken down into packets before being sent across the internet, then reassembled at the destination. |
| Topology | Noun | The arrangement or layout of the connections (links, nodes, etc.) of a computer network. | The network topology (e.g., star, mesh, bus) can affect its performance, scalability, and reliability. |
| Leased Line | Noun | A private telecommunications circuit between two or more locations provided under a commercial contract. | The bank uses a leased line for secure, dedicated communication between its main office and branches. |
| MPLS (Multiprotocol Label Switching) | Noun | A routing technique in telecommunications networks that directs data based on short path labels. | MPLS is often used by enterprises to create high-performance, reliable WANs for their critical applications. |
| Data Center | Noun | A facility used to house computer systems and associated components, such as telecommunications and storage. | Our company's servers and critical WAN concepts infrastructure are located in a secure data center. |
Common Phrases Used
Beyond individual telecommunications terms, knowing common phrases will help you sound more natural and understand discussions about Wide Area Networks. These expressions are frequently used by IT professionals and are essential for practical communication. Familiarizing yourself with these can also help overcome pronunciation problems with common IT acronyms as you hear them in context.
| Phrase | Usage Explanation | Example Sentence(s) |
|---|---|---|
| Connect to the network | Used when establishing a link between a device (computer, phone) and a network system (LAN or WAN). | Please connect to the network using your provided credentials to access shared files. |
| Experiencing high latency | Describes a situation where there are significant delays in data transmission, leading to slow responses. | Users are experiencing high latency during peak hours, slowing down access to cloud applications. |
| Check the bandwidth usage | Said when investigating network performance issues, specifically to see how much data transfer capacity is used. | If the internet is slow, the IT department will first check the bandwidth usage to identify bottlenecks. |
| Configure the router settings | Refers to the process of setting up or modifying the operational parameters of a network router for the WAN. | The network administrator had to configure the router settings to prioritize video conferencing traffic. |
| Set up a VPN connection | Used when creating a secure, encrypted tunnel for network access, often for remote work or accessing WANs. | To work from home securely, you need to set up a VPN connection to the company's main server. |
| Secure the perimeter | Refers to implementing security measures (like firewalls) at the edge of the network to protect internal resources. | To protect our data communication words and systems, we must secure the perimeter of our WAN against external threats. |
| Resolve connectivity issues | The process of troubleshooting and fixing problems that prevent devices from accessing the network or internet. | The support team is working to resolve connectivity issues affecting our branch offices. |
