Tech Terms: Mobile OS

A mobile operating system, also called a mobile OS, is an operating system that is specifically designed to run on mobile devices such as mobile phones, smartphones, PDAs, tablet computers and other handheld devices. The mobile operating system is the software platform on top of which other programs, called application programs, can run on mobile devices.

Tips & Tricks: Turn off Cortana

But what if you don’t want Cortana listening in on you whatsoever? Microsoft unfortunately disabled all overt methods for disabling the digital assistant in the Windows 10 Anniversary Update, along with a handful of other things. Don’t despair. There’s still a workaround for closing her eyes and ears using a quick registry edit. Here’s how to kill Cortana if you don’t want the digital assistant to share your searches and other info with Microsoft’s servers.

Tech Terms: Server Operating System

A server operating system, also called a server OS, is an operating system specifically designed to run on servers, which are specialized computers that operate within a client/server architecture to serve the requests of client computers on the network.

The server operating system, or server OS, is the software layer on top of which other software programs, or applications, can run on the server hardware. Server operating systems help enable and facilitate typical server roles such as Web server, mail server, file server, database server, application server and print server.

Most Popular Server Operating Systems
Popular server operating systems include Windows Server, Mac OS X Server, and variants of Linux such as Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server.According to SpiceWorks, this list is the most deployed on-premises server operating systems (August 2016):

  • Windows Server 2003
  • Windows Server 2008
  • Windows Server 2012
  • Linux (excluding RHEL)
  • Windows Server 2000
  • Red Hat Enterprise Linus (RHEL)

Tips & Tricks: Launch New Instance

Those taskbar icons can also be used to quickly launch a second (or third, or fourth, or…) instance of a program—a fresh browser window alongside an already populated one, for instance, or another Windows Explorer window.

Doing so is easy: Just hold down the Shift button, then open the program as you normally would, either via a left click of the mouse or the aforementioned quick-launch keyboard trick. A new, clean version of the software appears alongside the one you already have open.

Tech Terms: Operating Systems

The operating system (OS) is the most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs and applications. Computer operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the storage drives, and controlling peripheral devices, such as printers.

For large systems, the operating system has even greater responsibilities and powers. It is like a traffic cop — it makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system.

A Software Platform for Applications
Operating systems provide a software platform on top of which other programs, called application programs, can run. The application programs must be written to run on top of a particular operating system. Your choice of operating system, therefore, determines to a great extent the applications you can run. For PCs, the most popular operating systems are DOS, OS/2, and Windows, but others are available, such as Linux.

Classification of Operating systems

  • Multi-user: Allows two or more users to run programs at the same time. Some operating systems permit hundreds or even thousands of concurrent users.
  • Multiprocessing : Supports running a program on more than one CPU.
  • Multitasking : Allows more than one program to run concurrently.
  • Multithreading : Allows different parts of a single program to run concurrently.
  • Real time: Responds to input instantly.

General-purpose operating systems, such as DOS and UNIX, are not real-time.
User Interaction With the OS
As a user, you normally interact with the operating system through a set of commands. For example, the DOS operating system contains commands such as COPY and RENAME for copying files and changing the names of files, respectively. The commands are accepted and executed by a part of the operating system called the command processor or command line interpreter. Graphical user interfaces allow you to enter commands by pointing and clicking at objects that appear on the screen.

Most Popular Desktop Operating Systems
The three most popular types of operating systems for personal and business computing include Linux, Windows and Mac.

Windows
Microsoft Windows is a family of operating systems for personal and business computers. Windows dominates the personal computer world, offering a graphical user interface (GUI), virtual memory management, multitasking, and support for many peripheral devices.
Mac

Mac OS is the official name of the Apple Macintosh operating system. Mac OS features a graphical user interface (GUI) that utilizes windows, icons, and all applications that run on a Macintosh computer have a similar user interface.

Linux
Linux is a freely distributed open source operating system that runs on a number of hardware platforms. The Linux kernel was developed mainly by Linus Torvalds and it is based on Unix.

According to Netmarketshare.com, the most used desktop operating system and versions used on PCs in July 2017 are:

  • Windows 7 (48.91%)
  • Windows 10 (27.63%)
  • Windows 8.1 (6.48%)
  • Windows XP (6.10%)
  • Mac OS X 10.12 (3.52%)
  • Linux (2.53%)
  • Windows 8 (1.42%)
  • Mac OS X 10.11 (1.17%)
  • Mac OS X 10.10 (0.76%)

Mobile Operating Systems
In the same way that a desktop OS controls your desktop or laptop computer, a mobile operating system is the software platform on top of which other programs can run on mobile devices, however, these systems are designed specifically to run on mobile devices such as mobile phones, smartphones, PDAs, tablet computers and other handhelds. The mobile OS is responsible for determining the functions and features available on your device, such as thumb wheel, keyboards, WAP, synchronization with applications, email, text messaging and more. The mobile OS will also determine which third-party applications (mobile apps) can be used on your device.

Tips & Tricks: Magnify What Camera Sees

The ability to zoom in on real-world images might prove helpful in all kinds of situations, such as when you’re squinting at a menu in a dimly-lit restaurant. To use it, go to Settings, open General, choose Accessibility, and then tap Magnifier and turn the feature on. You can also enable auto-brightness at this time, which means the camera screen will react to ambient light levels.

With this toggle set to on, you can launch the iOS Camera app and triple-tap the Home button to bring up the Magnifier option. Use the slider at the bottom of the screen to take a closer look at anything, from a photograph to a block of text.

Tech Terms: Android Mobile Security

Mobile security applications for Google’s Android platform help protect Android smartphone and tablet mobile devices from malware threats as well as unauthorized access following accidental loss or theft of the device.

Additional security features frequently offered by Android mobile security apps include securing data on the device, VPN connectivity for protecting data in transit, scanning websites for potential phishing schemes or other fraudulent activity, helping users locate their device if lost or stolen, and more.

Android mobile security applications are available from Google as well as well-known third-party security vendors such as Lookout, Avast, Kaspersky, Symantec and Qihu.

Tips & Tricks: Write on Attachments

Sometimes, an email attachment just doesn’t convey enough information on its own. So annotate it with the Mail client built into iOS. Digital scribbles, text overlays, a zoom-in magnification window, digital signatures—you can add all of these on top of email attachments.

To modify an attachment you’ve received (you can still review your email before sending it), tap and hold it until the Share menu appears. Then pick Markup and Reply from the list. For a file you’ve attached to a new email, tap the attachment and choose Markup.

Tech Terms: EMM

Enterprise Mobility Management (EMM) takes a comprehensive approach to securing and managing the use of smartphones, tablets and other mobile devices in enterprise environments.

Companies are faced with a wide variety of security and productivity concerns that stem from the increasing number of mobile devices brought into the workplace environment by employees for use and connectivity on corporate networks (also known as “Bring Your Own Device,” or BYOD), and enterprise mobility management is one holistic strategy for managing these concerns.
