The motherboard is the main printed circuit board in a computer, connecting all components like the CPU, memory, and peripherals.

Microprocessors, integrating entire CPUs onto a single chip, are the defining characteristic and switching devices for fourth-generation computers.

DMA stands for Direct Memory Access, a feature that allows certain hardware subsystems to access main system memory independently of the CPU.

Line spacing refers to the vertical distance between lines of text in a document, which can be adjusted to improve readability and layout.

UNIVAC stands for Universal Automatic Computer, which was one of the earliest commercial computers designed primarily for business and administrative data processing.

A CPU (Central Processing Unit) fundamentally contains a control unit, which manages and coordinates all operations within the computer system.

A digital clock is a device that displays time numerically, representing data in discrete digits, which is characteristic of digital devices.

A multiprocessor system features a computer architecture with more than one central processing unit (CPU), significantly enhancing overall performance and throughput.

In Microsoft Word, the "Ctrl + F" shortcut opens the Find dialog box, enabling users to efficiently search for specific characters, words, or symbols.

Volatile memory, such as RAM, requires power to maintain the stored information and loses its content when the power is turned off.
