A Brief Description Preface Computers are some of the most versatile tools that we have available. They are capable of performing stunning feats of computation, they allow information to be exchanged easily regardless of their physical location, they simplify many every-day tasks, and they allow us to automate many processes that would be tedious or boring to perform otherwise.
However, computers are not "intelligent" as we are. They have to be told in no uncertain terms exactly what they're supposed to do, and their native languages are quite unlike anything we speak. Thus, there's a formidable language barrier between a person who wishes a computer to do something, and the computer that typically requires instructions in its native language, machine code, to do anything.
So far, computers cannot figure out what they are supposed to do on their own, and thus they rely on programs which we create, which are sets of instructions that the computer can understand and follow.
An Overview of Programs and Programming Languages In order to better communicate to our computers what exactly it is we want them to do, we've developed a wide range of programming languages to make the communication process easier.
Depending on the type of project, there are many factors that have to be considered when choosing a language. Here is a list of some of the more noteworthy ones: Compiled, interpreted, or JIT-compiled Compiled languages are translated to the target machine's native language by a program called a compiler.
This can result in very fast code, especially if the compiler is effective at optimizing, however the resulting code may not port well across operating systems and the compilation process may take a while.
Interpreted languages are read by a program called an interpreter and are executed by that program. While they are as portable as their interpreter and have no long compile times, interpreted languages are usually much slower than an equivalent compiled program.
Finally, just-in-time compiled or JIT-compiled languages are languages that are quickly compiled when programs written in them need to be run usually with very little optimizationoffering a balance between performance and portability. High or Low Level Level, in this case, refers to how much the nature of the language reflects the underlying system.
In other words, a programming language's level refers to how similar the language is to a computer's native language.
The higher the level, the less similar it is. A low-level language is generally quite similar to machine code, and thus is more suitable for programs like device drivers or very high performance programs that really need access to the hardware. Generally, the term is reserved for machine code itself and assembly languages, though many languages offer low-level elements.
Since a low-level language is subject to all the nuances of the hardware it's accessing, however, a program written in a low-level language is generally difficult to port to other platforms. Low level languages are practically never interpreted, as this generally defeats the purpose.
A high-level language focuses more on concepts that are easy to understand by the human mind, such as objects or mathematical functions. A high-level language usually is easier to understand than a low-level language, and it usually takes less time to develop a program in a high-level language than it does in a low-level language.
As a trade-off one generally needs to sacrifice some degree of control over what the resulting program actually does.
It is not, however, impossible to mix high-level and low-level functionality in a language.
Type System A type system refers to the rules that the different types of variables of a language have to follow. Some languages including most assembly languages do not have types and thus this section does not apply to them.
Strong or Weak A strong typing system puts restrictions on how different types of variables can be converted to each other without any converting statements. An ideal strong typing system would forbid implicit "casts" to types that do not make any sense, such as an integer to a Fruit object.
A weak typing system would try to find some way to make the cast work. Many languages require variables' types to be explicitly defined, and thus rely on manifest typing.
Some however, will infer the type of the variable based on the contexts in which it is used, and thus use inferred typing. If the language is dynamically type checked, then the types are checked at run-time. Safe or Unsafe These refer to the degree to which a language will prohibit operations on typed variables that might lead to undefined behavior or errors.
A safe language will do more to ensure that such operations or conversions do not occur, while an unsafe language will give more responsibility to the user in this regard. These typing characteristics are not necessarily mutually exclusive, and some languages mix them.
Supported paradigms A programming paradigm is a methodology or way of programming that a programming language supports. Here is a summary of a few common paradigms: Declarative A declarative language will focus more on specifying what a language is supposed to accomplish rather than by what means it is supposed to accomplish it.
How to Write a Brief Description of Yourself. In this Article: Article Summary Sample Short Biographies Coming up with Ideas for Your Description Writing a Professional Bio Crafting a Summary for Your Resume Creating an Informal Blurb Revising Your Description Community Q&A Writing a brief description of yourself can be tough. Fortunately, there are a few tricks that can make it easier to. To write a narrative essay, you’ll need to tell a story (usually about something that happened to you) in such a way that he audience learns a lesson or gains insight.. To write a descriptive essay, you’ll need to describe a person, object, or event so vividly that the reader feels like he/she could reach out and touch it.. Tips for writing effective narrative and descriptive essays. Experience has suggested the brief introductory statement of main literary principles, too often taken for granted by teachers, with much resulting haziness in the student's mind.
Such a paradigm might be used to avoid undesired side-effects resulting from having to write one's own code. Functional Functional programming is a subset of declarative programming that tries to express problems in terms of mathematical equations and functions.
It goes out of its way to avoid the concepts of states and mutable variables which are common in imperative languages. Generic Generic programming focuses on writing skeleton algorithms in terms of types that will be specified when the algorithm is actually used, thus allowing some leniency to programmers who wish to avoid strict strong typing rules.How to Write an Essay.
Throughout your academic career, you will often be asked to write essays. You may have to work on an assigned essay for class, enter an essay contest or write essays for college admissions.
This article will show you. Creative brief sample for advertising and design projects with consumer insights, audience profile, media and schedule. Hey Jellybean! Sounds like a fun survey project. When doing in person interviews, like having senior managers contact customers directly poses different challenges than surveying through an automated email list or pop up campaign.
If you're doing business in real estate, one of the greatest skills you can acquire is the ability to create compelling property listings that sell properties quickly.
The idea of 'selling' is something that scares a lot of people out of real estate. I used to HATE the idea of being a 'real estate salesman' because of all the negative connotations that came with the territory (in my mind, anyway).
