For simple web research, word processing and similar tasks, there’s nothing like the lightweight Chromebook. One of our most inexpensive laptops for school, Chromebook is fast and intuitive - and did we mention how affordable they are? Shop our entire school Chromebook lineup. Tablets likely aren’t ideal as a student’s only computing device, but they’re great for off-hours pursuits like social media, podcasts, and so on. Browse all Lenovo tablets for school. Finally, remember that a student laptop needs to last a long time, whether you’re attending a 2-year institution, a 4-year one or are "in it" all the way through graduate school. So, as you shop, pay attention to processor speeds, RAM allotments, and the other critical specs. Try to buy something that will last for the duration of your studies. Not sure where to start? Check out our Laptop Buying Guide for tips on what to look for when buying a laptop for college, school, or even gaming. Expect more from a modern computer with an SSD. Today’s computers look different, because they are different. With solid-state drives (SSDs) and the latest in technology, you get, speed, security, durability, and great design.
Are there parallels we can draw and learn from between computer security and the human immune system? I often like to compare digital polymorphic file-infector viruses (such as Virut and Sality, both commonly found throughout the past decade) and biological retroviruses such as HIV. File-infector viruses add malicious data to your computer's files. We unknowingly spread the viral code to other files by launching our favorite programs and sharing infected files with others. HIV works in an astonishingly similar way. When humans contract HIV, the virus infects a type of cell in the immune system called a T cell. Not only is it an evolutionary snub that our own immune systems get hijacked by this virus, resulting in AIDS, but the virus literally becomes part of us, inserting its viral code into our own DNA. Even if the virus is destroyed with treatments such as HAART, the treatment is not permanent, since infected cells will produce new copies of the virus.
“We really do have quite phenomenal amounts of computing at our hands today,” he says. Enter the scientist-coder. A powerful computer is useless without software capable of tackling research questions - and researchers who know how to write it and use it. “Research is now fundamentally connected to software,” says Neil Chue Hong, director of the Software Sustainability Institute, headquartered in Edinburgh, UK, an organization dedicated to improving the development and use of software in science. Scientific discoveries rightly get top billing in the media. But Nature this week looks behind the scenes, at the key pieces of code that have transformed research over the past few decades. Although no list like this can be definitive, we polled dozens of researchers over the past year to develop a diverse line-up of ten software tools that have had a big impact on the world of science. The first modern computers weren’t user-friendly.
Summary: Across 33 rich countries, only 5% of the population has high computer-related abilities, and only a third of people can complete medium-complexity tasks. One of usability’s most hard-earned lessons is that you are not the user. This is why it’s a disaster to guess at the users’ needs. Since designers are so different from the majority of the target audience, it’s not just irrelevant what you like or what you think is easy to use - it’s often misleading to rely on such personal preferences. For sure, anybody who works on a design project will have a more accurate and detailed mental model of the user interface than an outsider. If you target a broad consumer audience, you will also have a higher IQ than your average user, higher literacy levels, and, most likely, you’ll be younger and experience less age-driven degradation of your abilities than many of your users. There is one more difference between you and the average user that’s even more damaging to your ability to predict what will be a good user interface: skills in using computers, the Internet, and technology in general.
