Computer Fundamentals and Applications

(b) DeepSeek

Liang Wenfeng (梁文锋) is the founder of DeepSeek, the Chinese AI company whose DeepSeek-V3 and DeepSeek-R1 models gained worldwide attention in early 2025.

(c) Processing data and instructions

The CPU (Central Processing Unit) is the "brain" of the computer: it fetches instructions from memory, decodes them, and executes the arithmetic, logic and control operations on data. Storage is the job of memory (RAM/ROM/disk), input/output devices are managed by the I/O controller and operating system, and internet connectivity is handled by network hardware — so options (a), (b) and (d) describe other components, not the CPU's primary function.

(None of the above)
In MS-Word, Ctrl + Enter inserts a manual page break; it does not display a dialog box.
(For reference: Ctrl + F opens Find; Ctrl + H opens Find and Replace.)

(c) Cell

The intersection of a row and a column on a worksheet is called a cell. A cell is identified by its address, such as A1 or B5, where the letter denotes the column and the number denotes the row.

(d) Template

A template is a ready-made file that contains pre-designed slide layouts, colour schemes, fonts and background styles. You can apply it to a new presentation so that all slides follow the same design without formatting each one manually.

(c) Viewing and navigating web pages

A web browser (such as Chrome, Firefox or Edge) is client software that requests web pages from a web server using HTTP/HTTPS, interprets the HTML, CSS and JavaScript it receives, and displays the rendered page. It also lets the user move between pages through hyperlinks, the address bar, bookmarks and navigation buttons. Creating spreadsheets, playing multimedia and writing documents are jobs of application software, not of the browser's core purpose.
