What Are Some Examples of Operating Systems? Some examples of operating systems include Apple macOS, Microsoft Windows, Google’s Android OS, Linux Operating System, and Apple iOS. Android is a Unix-like mobile operating system that you’ll find on your mobile phone or tablet, depending on the device brand.

An operating system has three main functions: (1) manage the computer’s resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software.

Linux is an example of an operating system. With sequential processing techniques, multiple tasks are performed at the exact same time. The most recent version of Windows is Windows XP. File management programs can be used to copy files from one storage medium to another.

Examples of applications include word processors, database programs, web browsers, development tools, image editors and communication platforms. Applications use the computer’s operating system (OS) and other supporting programs, typically system software, to function.

Kernel and Userspace; The two parts that make up an operating system are the kernel and the user space.

Operating system

• Process management.
• Interrupts.
• Memory management.
• File system.
• Device drivers.
• Networking.
• Security.
• I/O.

Components of Operating System

• Kernel. The kernel in the OS provides the basic level of control on all the computer peripherals.
• Process Execution.
• Interrupt.
• Memory Management.

The Linux kernel consists of several important parts: process management, memory management, hardware device drivers, filesystem drivers, network management, and various other bits and pieces.

A kernel is the central part of an operating system. It manages the operations of the computer and the hardware, most notably memory and CPU time. There are five types of kernels: A micro kernel, which only contains basic functionality; A monolithic kernel, which contains many device drivers.

The kernel performs its tasks, such as running processes, managing hardware devices such as the hard disk, and handling interrupts, in this protected kernel space. In contrast, application programs like browsers, word processors, or audio or video players use a separate area of memory, user space.

The term BIOS (Basic Input/Output System) was created by Gary Kildall and first appeared in the CP/M operating system in 1975, describing the machine-specific part of CP/M loaded during boot time that interfaces directly with the hardware. (A CP/M machine usually has only a simple boot loader in its ROM.)

Universal Serial Bus

The working principle of a CMOS (complementary metal oxide semiconductor) image sensor was conceived in the latter half of the 1960s, but the device was not commercialized until microfabrication technologies became advanced enough in the 1990s.

BIOS (basic input/output system) is the program a computer’s microprocessor uses to start the computer system after it is powered on. It also manages data flow between the computer’s operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse and printer.

BIOS, computing, stands for Basic Input/Output System. The BIOS is a computer program embedded on a chip on a computer’s motherboard that recognizes and controls various devices that make up the computer. The purpose of the BIOS is to make sure all the things plugged into the computer can work properly.

A computer’s Basic Input Output System and Complementary Metal-Oxide Semiconductor together handle a rudimentary and essential process: they set up the computer and boot the operating system. The BIOS’s primary function is to handle the system setup process including driver loading and operating system booting.

BIOS uses Flash memory, a type of ROM. The BIOS software has a number of different roles, but its most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere.

The BIOS has 4 main functions:

• POST – Test computer hardware insuring hardware is properly functioning before starting process of loading Operating System.
• Bootstrap Loader – Process of locating the operating system.
• BIOS – Software / Drivers which interfaces between the operating system and your hardware.

The BIOS is critical in the device’s booting process. These functions are essential for the smooth running of the device. They are: Initializing and Testing Hardware Components:For a computer device to function normally, certain hardware components e.g. hard disk, graphics card and keyboard have to be working.

Advantages of Updating Computer BIOS (Basic Input Output System)

• The overall performance of your computer improves.
• Compatibility issues are treated.
• Booting time is shorten.

Limitations of BIOS (Basic Input Output System) End Users may destroy Basic I/O System Memory while updating it. It cannot boot from large storage drives.

Installing (or “flashing”) a new BIOS is more dangerous than updating a simple Windows program, and if something goes wrong during the process, you could end up bricking your computer. Since BIOS updates don’t usually introduce new features or huge speed boosts, you probably won’t see a huge benefit anyway.

Here are some common things you can do in most BIOS systems:

• Change the Boot Order.
• Load BIOS Setup Defaults.
• Flash (Update) BIOS.
• Remove a BIOS Password.
• Create a BIOS Password.
• Change the Date and Time.
• Change Floppy Drive Settings.
• Change Hard Drive Settings.
