Software is a collection of instructions and data that tell a computer how to work. This is in contrast to physical hardware, from which the system is built and actually performs the work. In computer science and software engineering, computer software is all information processed by computer systems, including programs and data. Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own.
At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). A machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed to "jump" to a different instruction, or is interrupted by the operating system. As of 2015, most personal computers, smartphone devices and servers have processors with multiple execution units or multiple processors performing computation together, and computing has become a much more concurrent activity than in the past.
The majority of software is written in high-level programming languages. They are easier and more efficient for programmers because they are closer to natural languages than machine languages. High-level languages are translated into machine language using a compiler or an interpreter or a combination of the two. Software may also be written in a low-level assembly language, which has strong correspondence to the computer's machine language instructions and is translated into machine language using an assembler.

Hi,
I am a newb interested in prehistory: I'd like to gaze on night skies of 5000 years ago, is this possible please?
I already have Space.Com 'Night Sky Explorer' but this only gets me back to 200 BC.
Please advise.
Many thanks ;)

I'm currently on a Mech Eng undergrad course going into my final year. I have used a number of drawing and simulation packages.
My question is, in the industrial world what is the most used piece of CAD software? I am not so good with Pro/E and so so with AutoCAD. We are learning Solidworks...
Hello everyone!
I have recently decided that I want to pursue a career in software engineering, but the problem is that I haven’t taken many courses in it. I’ll briefly describe where I’m at now:
I’m a senior physics major, and I had originally planned on doing some sort of medical physics or...
I'm currently majoring in EE, and it's my first semester and I realized the math class I am in is like so far behind what I am suppose to be in. I know EE is a GREAT job, lots of money, lots of job demand (lots of people want to hire you), and such and such, but the math and physics is extremely...
Hi
Pretty simple, just what the title says, anyone know of some good drawing software for Mechanical Engineering?
What I mean by drawing software is software that can make diagrams such as MOHr Strain Diags, Beam Diags, and Freebody drawings, etc.?
Thanks
Hey folks,
I am looking for something free to help me out here. I have experimental data that consists of the temperature and pressure of a gas over time. That is I have (T1,P1), (T2,P2),...(Tn,Pn) where n might be upward of a 500.
I would like to be able to determine the specific volume...

I am in my 3rd year of a physics b.s. program. I have been taking a few courses (not many) to get a computer science concentration. I have become increasingly interested in software engineering (not just programming), so I'm looking into how hard that is going to be with a physics degree...
Hi
Can anyone recommend any tools for creating resources for teaching chemistry and molecular sciences? I used rasmol many years ago but I believe that has been superceded by Jmol so i will download that and have a look. I know Isis Draw is free. I have downloaded it and will investigate

I need something that I can use to draw a few simple 2D images, that don't have to look pretty. I really mean "draw" (with the mouse) and not generate from a formula, and a minimum requirement is that the program can at least let me try to draw a smooth curve with the mouse and then smooth it...
So, when I'm looking at the college I'm pretty sure I want to go to, they offer CS. At some colleges, I've noticed that they have CS AND software engineering. So, is there a difference?
do you guys know any free mathematical software that can help me find the area under a graph which can't be intergarted using just a level skills.
i already checked autograph but it kinda sucks and i looked other forums but didnt find a thing about this.

Hi,
What is the reason the most of the time, the software are much more expensive than the hardware components.
If there is any important machine that is worth millions, then why its software is also too much expensive. Is it because of its complicated tasks or is there any other reason ? !
I've been reading (and a few people mentioned it as well) that electronics, software etc is moving to Asia. By moving I mean that you can hire a company there to do the job for you for less money because salaries there are lower. The reason I can think of is that electronics / software doesn't...
