MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Digital systems often use a number of registers to store temporary variables. This group of registers, called a register file, is usually built as a small, multiported SRAM array because it is more compact than an array of flip-flops.

Detailed explanation-2: -A variable is a named memory location which temporarily stores data that can change while the program is running. A constant is a named memory location which temporarily stores data that remains the same throughout the execution of the program. The type of a variable indicates what kind of value it will store.

Detailed explanation-3: -Detailed Solution. The correct answer is option 2 i.e., Cached data. Cached data is known as temporarily stored data. Cached data make loading time faster.

Detailed explanation-4: -Temporary variables are usually named with identifiers that abbreviate the word temporary, such as temp, tmp or simply t, or with common metasyntactic variable names, the most common of which are foo, bar, baz (see also foobar).

Detailed explanation-5: -Many variables store numbers and strings, like the ones above. Variables can also store other types of data, like lists, dictionaries, and Boolean values (true/false). We’ll start by learning numbers and strings, and dive into advanced types later.
