Set-builder notation can be used to describe a set that is defined by a predicate, that is, a logical formula that evaluates to true for an element of the set, and false otherwise. [2] In this form, set-builder notation has three parts: a variable, a colon or vertical bar separator, and a predicate. Thus there is a variable on the left of the ...
2-in-1s can have a hybrid or a convertible form, often dubbed 2-in-1 detachable and 2-in-1 convertibles respectively, but are distinguished by the ability to run a desktop OS, such as Windows 10. 2-in-1s are often marketed as laptop replacement tablets. [42] 2-in-1s are often very thin, around 10 millimetres (0.39 in), and light devices with a ...

A notebook computer or notebook is, historically, a laptop whose length and width approximate that of letter paper (8.5 by 11 inches or 220 by 280 millimetres). [a] The term notebook was coined to describe slab-like portable computers that had a letter-paper footprint, such as Epson's HX-20 and Tandy's TRS-80 Model 100 of the early 1980s.

But the set builder notation is a notation commonly used for both sorts of specifications, and, for many sources the use of braces for specifications by extension is a part of set builder notation. I agree that it is possible to consider that Roster notation is not a special case of set builder notation, but, as for most conventions, this is an ...
In set theory, X Y is the notation representing the set of all functions from Y to X. As "2" can be defined as {0, 1} (see, for example, von Neumann ordinals), 2 S (i.e., {0, 1} S) is the set of all functions from S to {0, 1}. As shown above, 2 S and the power set of S, P (S), are considered identical set-theoretically.
Sizes of classic subnotebooks (2001's ThinkPad s30, 10.4") and early netbooks (2008's Eee PC 901, 8.9"); note to reduced keycaps size. As typical laptop sizes have decreased over the course of the 2010s, and other distinguishing features have become mainstream, the distinction between regular-size and 'subnotebook' laptops has largely disappeared.
