How to convert a PDF to JPG for easy viewing on any device

How to easily convert a PDF to JPG for easy viewing on any device.... There are plenty of worthwhile reasons to convert a Portable Document Format (PDF) to a JPG image (it’s different from a GIF, you know). Although PDF files are a fantastic way to package a slew of text and image documents together, they often require an external application or plug-in and are unnecessary if you want just a single page or image. But to make that transition, you need to know how to convert a PDF to JPG. There Are Many Different Ways To Do This , But My Favorite Method using Zamzar — Free web tool Online tools can typically be used from any computer or mobile device. Since they don’t take up any room on your computer and tend to be speedy little converters, you may prefer them to other options. Their only downside is that they tend to be a little limited in the amount of data you can convert at one time, which makes them difficult to use for larger PDF files. Still, they can be a useful tool...

Priority Interrupts | (S/W Polling and Daisy Chaining)

Priority Interrupts | (S/W Polling and Daisy Chaining) To summarize, when I/O devices are ready for I/O transfer, they generate an interrupt request signal to the computer. The CPU receives this signal, suspends the current instructions it is executing and then moves forward to service that transfer request. But what if multiple devices generate interrupts simultaneously. In that case, we have to have a way to decide which interrupt is to be serviced first. In other words, we have to set a priority among all the devices for systemic interrupt servicing. The concept of defining the priority among devices so as to know which one is to be serviced first in case of simultaneous requests is called priority interrupt system. This could be done with either software or hardware methods. SOFTWARE METHOD – POLLING In this method, all interrupts are serviced by branching to the same service program. This program then checks with each device if it is the one generating th...

These Are The Fastest Growing Programming Languages - Tech Trone

These Are The Fastest Growing Programming Languages A lot of new programming languages are making their way to the top and JavaScript is holding the top position for the past few years. Seems like the situation is about to change and JavaScript may soon be dethroned by Python. Python is one of the fastest growing languages and by 2019, it would have a clear domination in the programming community. This is a prediction made by StackOverflow, a programming Q&A center. With more than 50 million amateur and professional developers visiting the website, StackOverflow is one of the qualified companies to make such a survey. Based on the huge increase in the questions from developers on Python and the data they have collected, StackOverflow made this survey possible. Stack Overflow data scientist David Robinson said in a blog post that, “The term ‘fastest-growing’ can be really hard to define precisely , but we make the case that Python has a solid claim to...
