UGC NET Questions (Paper – 1)

When a user visits a website, the browser may save images, scripts and other components in a local cache. On subsequent visits, it can load these elements from the cache instead of downloading them again, reducing bandwidth use and improving loading times. This caching mechanism is a standard ICT technique for optimising user experience on the web.

Option A:
This option correctly describes how caching works: the browser keeps temporary copies of page elements so that later visits are faster and require fewer network requests. This improves performance and reduces bandwidth consumption.

Option B:
This option incorrectly suggests that a browser cache can permanently delete all websites from the Internet. A cache only stores local copies; it has no control over whether sites exist on remote servers.

Option C:
Associating the cache with hardware circuit design confuses software-level optimisation with physical network engineering. Router circuits are designed by engineers, not by browser caching mechanisms.

Option D:
Caching does not prevent pages from being reloaded; it simply affects where elements are loaded from. Users can always refresh pages, and servers can force new downloads when content changes.

A browser cache stores recently accessed web pages, images and scripts on the local device so they can be loaded quickly when revisited. This reduces the need to download the same data repeatedly from remote servers, saving bandwidth and time. Caching is a standard performance optimisation in web browsing. Hence the temporary storage described is called a cache.

Option A:
Option A, cloud backup, keeps copies of files on remote servers for long-term protection rather than short-term speed improvements. It is not maintained automatically by the browser for rendering webpages.

Option B:
Option B is correct because the term cache in computing consistently refers to temporary storage that accelerates repeated access to data. Browsers explicitly label their performance-related storage as cache in their settings menus.

Option C:
Option C, archive, usually denotes long-term storage of historical data that is rarely changed, which is contrary to the frequent updating that occurs in caches.

Option D:
Option D, registry entry, is a Windows-specific configuration record and is not used for storing downloaded web content.
