Monolithic kernels have a simpler design and consist of a single code that communicates with all hardware and software. Main roles include reading data from memory and writing data to memory, processing execution orders, determining how data is received and sent by devices, such as the monitor, keyboard and mouse and determining how to interpret data received from networks. This provides basic-level control over all of the computer hardware devices. Three Easily Defined Operating System Components Kernel Which features are defined as part of the OS vary with each OS. The OS consists of many components and features. Later in the decade, computers included many software programs, sometimes called libraries, which were linked together to create the beginning of today's operating systems. Some operating systems were developed in the 1950s, when computers could only execute one program at a time. In this regard, the OS acts as a comprehensive framework with which all applications can interact in a consistent way, vastly simplifying the whole development process. While it is possible for a software application to interface directly with hardware, the vast majority of applications are written for an OS, which allows them to take advantage of common libraries and not worry about specific hardware details. If several programs are running at the same time (such as an Internet browser, firewall, and antivirus), the OS will allocate the computer’s resources (memory, CPU, and storage) to make sure that each one of them receives what is needed to function. The OS also provides services to facilitate the efficient execution and management of, and memory allocations for, any additional installed software application programs. Storage devices such as internal and external drives. Network devices such as modems, routers and network connections. Output devices such as display monitors, printers and scanners. Input devices such as a keyboard and mouse. The operating system manages a computer's software hardware resources, including:
