In CSS, selectors are what allows you to target specific HTML elements and apply style to them. There are many selectors, which were added during evolution of Cascading Style Sheets (versions 1, 2, 3). Most basic and most used of them were added in versions 1 and 2, while CSS 3 focuses on more specizlized ones.

Encapsulation, in the context of C#, refers to an object's ability to hide data and behavior that are not necessary to its user. Encapsulation is used to restrict access to the members of a class so as to prevent the user of a given class from manipulating objects in ways that are not intended by the designer.
FIFO and LIFO are commonly heard terms when discussing many different fields. It is also a popularly used method in computing and accounting. Meaning of this abbreviations are, respectively: first in, first out and last in, first out. LILO (Last In, Last Out) is synonymous with FIFO and FILO (First In, Last Out) is synonymous with LIFO.
The ASP.NET MVC is a web application framework developed by Microsoft, which implements the model–view–controller (MVC) pattern. Based on ASP.NET, ASP.NET MVC allows software developers to build a web application as a composition of three layers: Model, View and Controller.
JIT (just-in-time) compilation converts MSIL to native code on demand at application run time, when the contents of an assembly are loaded and executed. Because the common language runtime supplies a JIT compiler for each supported CPU architecture, developers can build a set of MSIL assemblies that can be JIT-compiled and run on different computers with different machine architectures.
Basically, attribute is an information (metadata) that can be attached to your method, class, namespace, assembly etc. Once associated with a program entity, the metadata provided by an attribute can be queried at run time by using a technique called reflection and used in many ways.
Bubble sort, sometimes referred to as sinking sort, is a primitive sorting algorithm that repeatedly steps through the array of elements, compares each pair of adjacent items and swaps them if they are in the wrong order. The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted. The algorithm, which is a comparison sort, is named for the way smaller elements "bubble" to the top of the list. Although the algorithm is simple, it is too slow and impractical for most problems.
The Common Language Runtime (CLR) is the virtual machine component of .NET framework. It manages the execution programs written with .NET languages. A process known as just-in-time compilation converts compiled IL (Intermediate Language) code into machine instructions which the computer's CPU then executes.
A linked list is a linear collection of data elements called nodes, pointing to the next node by means of pointer. It is a data structure consisting of a group of nodes which together represent a sequence. Under the simplest form, each node is composed of data and a reference (in other words, a link) to the next node in the sequence; but there are more complex variants, which introduce additional links. This structure allows for efficient insertion or removal of elements from any position in the sequence.
