Commonly Used Terms in Computer System Servicing (TVL-CSS)
In Technical-Vocational-Livelihood – Computer Systems Servicing (TVL-CSS), understanding technical terms is essential for effective learning and application. These words are frequently used in lessons and practical tasks, making them important for both academic and real-world contexts.
Firewall – A network security device or software that monitors and controls incoming and outgoing data traffic. Ex. Without a firewall, your computer is more vulnerable to online threats.
Virus – A malicious code designed to alter, steal, or destroy data and disrupt system operations. Ex. A virus has infected your system, but your files are back-uped so you’re safe.
IP – Internet Protocol; a numerical label that identifies devices and enables communication over a network. Ex. The printer could not be accessed because its IP address was not configured properly.
Drivers – Specialized software that allows the operating system to communicate with hardware components. Ex. Outdated drivers can cause devices to stop working correctly.
Motherboard – The main printed circuit board (PCB) that houses the CPU, memory, and expansion slots/sockets. Ex. The motherboard was flooded with dust, it must be cleaned.
Memory – “RAM” volatile storage used by the system to temporarily hold data and instructions for processing. Ex. Upgrading the RAM improved the performance of the software applications.
Processor – The central processing unit (CPU) that executes instructions and performs calculations for the system. Ex. The processor must have been overheating for a long time.
Subnet – A logically divided portion of an IP network that improves management and efficiency. Ex. The subnet mask was wrong, so that is why it could not obtain an IP address.
Diagnostics – Systematic testing and analysis tools used to detect, identify, and resolve hardware or software issues. Ex. Run the diagnostics, maybe you can solve the problem with that.
Networking – The practice of connecting and managing computers and devices to exchange data and resources. (Ex. I find networking complex and difficult to understand, but it is interesting.)
Here is a video elaborating three of these terms, complete with definitions and example sentences.
Familiarity with these terms supports both classroom learning and practical application in TVL-CSS. Mastering them builds a strong foundation for future technical skills and industry readiness.
