The Babbage Difference Engine was the first computer built in 1822 and weighed over 700 kilograms. The computer used vacuum tubes and rotating machines with small capacitors to solve 29 different problems and variables. It was in 1942 that the modern digital computer was built. Unlike Babbage’s Difference Engine, modern computers have stored programs and perform several tasks simultaneously. Advances in technology have made computers smaller and more efficient. However, many people think of these computing devices as just another common technology product. But the truth is that computers offer more than logging in and watching movies, browsing the Internet, creating documents and creating activities. That said, here are some interesting facts about computers that you may not know about.
Press the Shift Key Five Times to Activate the Sticky Key
The Shift key is a modifier key found on a variety of keyboards and layouts that allows users to type an uppercase letter or enter a higher number. For example, you can hold down the SHIFT key and press A on the keyboard to create an uppercase letter A. Similarly, pressing and holding the SHIFT key and typing the number 1 on a US keyboard results in an exclamation mark (!). Usually, this is the key used to change the keyboard function. However, pressing the SHIFT key five times activates other functions, which are other modifier keys such as the Ctrl, Function, Windows and Alt keys. These are called sticky keys, which also help the SHIFT key to remain active, and you can change symbols or type letters without holding down the key. Many people accidentally or intentionally flip the sticky key by pressing SHIFT five times.
In general, the StickyKeys feature is considered an accessibility service designed for computer users with physical disabilities or those who cannot press multiple keys at the same time. These keys also allow users to press and release any modified key, and hold it until another key is pressed. Since starting sticky keys involves pressing the SHIFT key five times, disabling it requires the user to press three or more keys (Alt, Ctrl, Windows) at the same time.
Users can use Ease of Access Center to enable or disable the Sticky Keys keyboard shortcut.
There is a Recovery Mode in the Boot Window
Like any other electronic device, a computer’s operating system can have problems and not run properly. The Windows operating system includes an advanced boot option that allows the computer to enter recovery mode. This allows you to fix the problem internally before calling a technician to fix the problem. For example, users can use the system recovery option to restore their system to an earlier version, such as Windows 10 and Windows 8, without logging into the computer.
Computers in recovery mode also allow users to repair selected programs or files or perform diagnostic tests to identify errors that prevent certain functions. Since Windows comes in different versions, system recovery options vary and may include different options. Computer boot recovery mode also has a better mode where users can choose how to boot their computer. Users can run recovery mode on Windows machines by long pressing F2 and pressing ENTER 10 times. This causes a backflip and the computer enters recovery mode, where the user can choose to restore previous windows, repair the system, or restore lost data if the computer crashes.
You Can Sign in Without a Password
Typically, the most popular security feature of any computing device is a strong password made up of a combination of letters, numbers and symbols. This ensures that users and those who know the password are the only ones who can log into the system. But if you have a password protected computer, you can log in as a user. However, this login option restricts access to certain privileges and permissions, preventing users from accessing files and system settings. Logging in as a user requires the user to first create a new account, as the computer already has an existing administrator account. This is a good thing if different people use the computer at different times.
Each user will have an individual account, with files created for each user from a single computer that is stored and managed. Each account also has preferences, settings and files that other user accounts cannot access. When users start the computer, all user accounts are displayed on the start screen and they select their preferred account. If users do not have an administrator account password, they can use the computer to browse, share content, create files, and watch movies just like a standard computer. However, they are not allowed to access specific files that can only be accessed by the master account.
