KembaraXtra- Computer Terms – 3-finger salute
The three-finger salute is a keyboard command created by pressing Ctrl+Alt+Delete simultaneously on IBM-compatible PCs. Originally designed as a secure system interrupt, it allows users to reboot the system or access low-level system functions. In modern operating systems, it is commonly used to invoke security or system management screens, such as login prompts or task managers.

KembaraXtra- Computer Terms – 3G
3G, short for third generation, refers to the third generation of digital wireless communication technology defined by the International Telecommunications Union (ITU) It introduced significantly higher data transmission speeds, typically ranging from 144 Kbps to 2 Mbps, compared to second-generation systems. These improvements enabled mobile internet access, video calling, and multimedia messaging. Regions such as Western Europe and Japan were among the earliest and most extensive adopters of 3G services.

KembaraXtra- Computer Terms – 3GL
Short for third-generation language, 3GL refers to high-level programming languages developed for computers built using integrated circuit technology between roughly 1965 and 1970. These languages abstracted hardware details, making programming more accessible and portable. Examples include C, FORTRAN, BASIC, and Pascal, which are still influential today. Compared to low-level languages, 3GLs improved productivity and readability while remaining efficient.

KembaraXtra- Computer Terms – 3NF
3NF, or third normal form, is a database normalization standard used in relational database design. A table is in third normal form if it is already in second normal form and all its non-key attributes depend only on the primary key, not on other non-key attributes. Achieving 3NF reduces data redundancy and improves data integrity by ensuring that each fact is stored in only one place

KembaraXtra- Computer Terms – 3-nines availability
Three-nines availability describes a system reliability level of 99.9% uptime. This metric indicates that a system is expected to be unavailable for no more than approximately 8.76 hours per year. It is commonly used in service-level agreements (SLAs) to quantify acceptable downtime for networks, servers, and online services.

KembaraXtra- Computer Terms – 3Station
The 3Station was a diskless workstation developed by Bob Metcalfe at 3Com Coproration.. Designed to operate without local storage, it relied on network resources for booting and application execution. This architecture reduced hardware costs, simplified maintenance, and emphasized centralized management, making it an early example of network-centric computing.

KembaraXtra- Computer Terms – 400
In the Hypertext Transfer Protocol, 400 is a status code meaning Bad Request. It indicates that a server cannot process a client’s request due to malformed syntax, invalid formatting, or incorrect parameters. This error typically results from client-side issues, such as improperly constructed requests or corrupted data, and signals that the request must be corrected before being resent.

KembaraXtra- Computer Terms – 401
The 401 Unauthorized HTTP status code indicates that a client request cannot be fulfilled because it lacks valid authentication credentials. The server expects an Authorization header, and without it, access to the requested resource is denied. This response is commonly encountered when accessing protected web resources that require login credentials or tokens.

KembaraXtra- Computer Terms – 402
The 402 Payment Required HTTP status code signifies that access to a requested resource is contingent upon payment. Although reserved in the HTTP specification and rarely used in practice, it was intended to support digital payment systems by signaling that a transaction could not proceed without appropriate billing information.

KembaraXtra- Computer Terms – 403
The 403 Forbidden HTTP status code indicates that a server understands a client’s request but refuses to authorize it. Unlike a 401 error, authentication may not resolve the issue, as access is explicitly denied due to permission restrictions, policy rules, or security configurations.
