Exercise 1 A. HARDWARE: Corresponds to all physical and tangible parts of a computer: your electrical, electronic, electromechanical and mechanical components, cables, cabinets or boxes, peripherals of all kinds and any other physical element involved SOFTWARE: The word "software" refers to the logical equipment or software of a digital computer, and includes all the necessary software components to enable the completion of a specific task, as opposed to the physical components of the system (hardware). Such logical components include, among others, computer applications such as word processing, allowing the user to perform all tasks concerning text editing; software system, such as an operating system, which basically allows the rest of the programs function properly, facilitating interaction with the physical components and other applications also provides an interface to the user.

B. OPERATIVE SYSTEM: An operating system is a program or set of programs on a computer system that manages the hardware resources and provides services to application programs, running in privileged mode from previous and next left and vice versa. Types of operatives systems: Real-time Multi-user • Multi-tasking vs. single-tasking • Distributed • Embedded • •


INPUT DEVICES: In computing, an input device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance. Examples of input devices include keyboards, mouse, scanners, digital cameras and joysticks. Ex: keyboard, mouse, USB and cam.

OUTPUT DEVICES: An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form. Ex: laser printer, speakers, matrix printer and multimedia projector.

STORAGE DEVICE: Object storage is a storage architecture that manages data as objects, as opposed to other storage architectures like file systems which manages data as a file hierarchy and block storage which manages data as blocks within sectors and tracks. Each object typically includes the data itself, a variable amount of metadata, and a globally unique identifier.
