Portable computerA portable computer is a computer designed to be easily moved from one place to another, as opposed to those designed to remain stationary at a single location such as desktops and workstations. These computers usually include a display and keyboard that are directly connected to the main case, all sharing a single power plug together, much like later desktop computers called all-in-ones (AIO) that integrate the system's internal components into the same case as the display.
Tablet computerA tablet computer, commonly shortened to tablet or simply tab, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have.
Human–computer interactionHuman–computer interaction (HCI) is the process through which people operate and engage with computer systems. Research in HCI covers the design and the use of computer technology, which focuses on the interfaces between people (users) and computers. HCI researchers observe how people interact with computers and design technologies that allow humans to interact with computers in new ways.
Wearable computerA wearable computer, also known as a body-borne computer or wearable, is a computing device worn on the body. The definition of 'wearable computer' may be narrow or broad, extending to smartphones or even ordinary wristwatches. Wearables may be for general use, in which case they are just a particularly small example of mobile computing. Alternatively, they may be for specialized purposes such as fitness trackers.

Personal digital assistantA personal digital assistant (PDA) is a multi-purpose mobile device which functioned as a personal information manager. Following a boom in the 1990s and 2000s, PDAs were mostly displaced in the early 2010s by the widespread adoption of smartphones and tablet computers. In particular, smartphones based on iOS and Android took their place, causing a rapid decline in PDA usage.
5GFifth-generation mobile telecommunications standard5G is the fifth and current generation of cellular network technology and the successor to 4G. In common commercial use, the term refers primarily to mobile networks based on the 3rd Generation Partnership Project (3GPP) 5G system and its New Radio (NR) air interface, which were first specified in 3GPP Release 15.
BIOSIn computing, BIOS or the Basic Input/Output System is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup). On a computer using BIOS firmware, the firmware comes pre-installed on the computer's motherboard. The name originates from the Basic Input/Output System used in the CP/M operating system in 1975.
3G3G is the third generation of cellular network technology. These networks were rolled out beginning in the early 2000s and represented a significant advancement over the second generation (2G) and associated technologies, such as GSM and cdmaOne, particularly in terms of data transfer speeds and mobile internet capabilities.
4G4G refers to the fourth generation of cellular network technology, introduced in the late 2000s and early 2010s. Compared to preceding third-generation (3G) technologies, 4G has been designed to support all-IP communications and broadband services, and eliminates circuit switching in voice telephony.
Mobile telephonyMobile telephony is the provision of wirelesstelephone services to mobile phones, distinguishing it from fixed-location telephony provided via landline phones. Traditionally, telephony specifically refers to voice communication, though the distinction has become less clear with the integration of additional features such as text messaging and data services.
Mobile appA mobile app or application is a computer program or software application designed to run on a mobile device such as a smartphone, tablet, or smartwatch. Mobile applications often stand in contrast to desktop applications which are designed to run on desktop computers, and web applications which run in mobile web browsers rather than directly on the mobile device.*As an Amazon Associate I earn from qualifying purchases.
