SaaS

Software as a service (SaaS /sæs/ is a software licensing and delivery model in which software is licensed on a subscriptionbasis and is centrally hosted. It is sometimes referred to as "on-demand software", and was formerly referred to as "software plus services" by Microsoft. SaaS applications are also known as on-demand software and Web-based/Web-hosted software.

SaaS is considered to be part of cloud computing, along with infrastructure as a service (IaaS), platform as a service (PaaS), desktop as a service (DaaS), managed software as a service (MSaaS), mobile backend as a service (MBaaS), datacenter as a service (DCaaS), and information technology management as a service (ITMaaS).

SaaS apps are typically accessed by users using a thin client, e.g. via a web browser. SaaS has become a common delivery model for many business applications, including office software, messaging software, payroll processing software, DBMS software, management software, CAD software, development software, gamification, virtualization, accounting, collaboration, customer relationship management (CRM), management information systems (MIS), enterprise resource planning (ERP), invoicing, field service management, human resource management (HRM), talent acquisition, learning management systems, content management(CM), geographic information systems (GIS), and service desk management.

DaaS

In computing, data as a service, or DaaS, is enabled by software as a service (SaaS). Like all "as a service" (aaS) technology, DaaS builds on the concept that its data product can be provided to the user on demand, regardless of geographic or organizational separation between provider and consumer. Service-oriented architecture (SOA), and the widespread use of API, has rendered the platform on which the data resides as irrelevant.

firmware

In computing, firmware[a] is a specific class of computer software that provides the low-level control for a device's specific hardware. Firmware can either provide a standardized operating environment for more complex device software (allowing more hardware-independence), or, for less complex devices, act as the device's complete operating system, performing all control, monitoring and data manipulation functions.

Typical examples of devices containing firmware are embedded systems, consumer appliances, computers, and computer peripherals; most electronic devices beyond the simplest contain some firmware.

Firmware is held in non-volatile memory devices such as ROM, EPROM, EEPROM, and Flash memory. Changing the firmware of a device was rarely or never done during its lifetime in the past but is nowadays a common procedure; some firmware memory devices are permanently installed and cannot be changed after manufacture. Common reasons for updating firmware include fixing bugs or adding features to the device. This requires ROM integrated circuits to be physically replaced, or EPROM or flash memory to be reprogrammed through a special procedure. Firmware such as the BIOS of a personal computer may contain only elementary basic functions of a device and may only provide services to higher-level software. Firmware such as the program of an embedded system may be the only program that will run on the system and provide all of its functions.

jailbreaking

Jailbreaking refers to privilege escalation on an Apple device to remove software restrictions imposed by Apple on iOS, iPadOS, tvOS, watchOS, bridgeOS and audioOS operating systems. Typically it is done through a series of kernel patches. A jailbroken device permits root access within the operating system and provides the opportunity to install software not available through the iOS App Store. Different devices and versions are exploited with a variety of tools. Apple views jailbreaking as a violation of the End-user license agreement, and strongly cautions device owners from attempting to achieve root access through exploitation of vulnerabilities.

daemon

n multitasking computer operating systems, a daemon (/ˈdiːmən/ or /ˈdeɪmən/)[1] is a computer program that runs as a background process, rather than being under the direct control of an interactive user. Traditionally, the process names of a daemon end with the letter d, for clarification that the process is in fact a daemon, and for differentiation between a daemon and a normal computer program. For example, syslogd is a daemon that implements system logging facility, and sshd is a daemon that serves incoming SSHconnections.
