- 2. WHAT IS A PLATFORM? • A platform is a group of technologies that are used as a base upon which other applications, processes or technologies are developed. • In personal computing, a platform is the basic hardware (computer) and software (operating system) on which software applications can be run. • Computers use specific central processing units (CPUs) that are designed to run specific machine language code.

- 7. HISTORY OF OPERATING SYSTEM • Operating systems were first developed in the late 1950s to manage tape storage • The General Motors Research Lab implemented the first OS in the early 1950s for their IBM 701 • In the mid-1960s, operating systems started to use disks • In the late 1960s, the first version of the Unix OS was developed • The first OS built by Microsoft was DOS. It was built in 1981 by purchasing the 86-DOS software from a Seattle company • The present-day popular OS Windows first came to existence in 1985 when a GUI was created and paired with MS-DOS.
- 8. TYPES OF OPERATING SYSTEMS • Batch-Operating System - The user of a batch operating system never directly interacts with the computer. In this type of OS, every user prepares his or her job on an offline device like a punch card and submit it to the computer operator. • SingleTasking - system can only run one program at a time. • Multi-tasking - operating system allows more than one program to be running in concurrency. • Real time OS - A real time operating system time interval to process and respond to inputs is very small. Examples: Military Software Systems, Space Software Systems.
- 9. • Network Operating System - Network Operating System runs on a server. It provides the capability to serve to manage data, user, groups, security, application, and other networking functions. • Mobile OS - Mobile operating systems are those OS which is especially that are designed to power smartphones, tablets, and wearables devices.
- 10. FUNCTIONS OF AN OPERATING SYSTEM • Process Management - Process management helps OS to create and delete processes. It also provides mechanisms for synchronization and communication among processes. • Memory Management - Memory management module performs the task of allocation and de- allocation of memory space to programs in need of this resources. • File Management - It manages all the file-related activities such as organization storage, retrieval, naming, sharing, and protection of files. • Device Management - Device management keeps tracks of all devices.This module also responsible for this task is known as the I/O controller. It also performs the task of allocation and de-allocation of the devices.
- 11. • I/O Management - One of the main objects of any OS is to hide the peculiarities of that hardware devices from the user. • Secondary- Storage Management - Systems have several levels of storage which includes primary storage, secondary storage, and cache storage. Instructions and data must be stored in primary storage or cache so that a running program can reference it. • Security - Security module protects the data and information of a computer system against malware threat and authorized access.
- 12. • Command Interpretation - This module is interpreting commands given by the and acting system resources to process that commands. • Networking - A distributed system is a group of processors which do not share memory, hardware devices, or a clock.The processors communicate with one another through the network. • Communication Management - Coordination and assignment of compilers, interpreters, and another software resource of the various users of the computer systems.
