Basic Computer: Abbreviations & Terminology MCQ — 15 Practice Questions with Answers

Explanation

HTTPS stands for HyperText Transfer Protocol Secure. Compared with plain HTTP, HTTPS is used for protected communication between the browser and the website. The stem gives the cue by comparing addresses that begin with HTTPS and HTTP. The reason is also true because the S in HTTPS stands for Secure and directly explains the added security indicated by the abbreviation. Therefore, both the assertion and reason are true, and the reason correctly explains the assertion.

Explanation

GUI means Graphical User Interface. In a GUI, the user interacts with the computer through visual elements such as windows, icons, menus and a pointer, instead of relying only on typed commands. The stem asks for the correct description, so the option mentioning these visual elements is the answer. Storage, programming languages and network cables are separate areas of computer terminology and do not define GUI.

Explanation

Both statements use standard CPU terminology. CPU expands to Central Processing Unit, the main processing part of a computer. Inside the CPU, the ALU, or Arithmetic Logic Unit, performs arithmetic operations such as addition and subtraction and logical comparisons such as greater than, less than or equal to. The stem asks whether the statements are correct, not which component stores data. Since both statements state accepted basic-computer facts, the correct option is “Both Statement 1 and Statement 2”.

Explanation

HTTPS means HyperText Transfer Protocol Secure. The assertion points to situations involving sensitive information, such as passwords or payment details. In such cases, HTTPS is preferred because it adds encryption to communication between the browser and the server. The reason states exactly this mechanism, so it is true and it explains why HTTPS is safer than plain HTTP for such pages. Hence both A and R are true, and R is the correct explanation of A.

Explanation

The question asks for the incorrect statement. RAM means Random Access Memory and is volatile memory. It temporarily holds the data and instructions that the CPU needs while a programme is running. When power is switched off, the contents of RAM are normally lost. Permanent storage is the role of devices such as HDD, SSD or other secondary storage, not RAM. Therefore, the statement that RAM stores data permanently after shutdown is incorrect.
