The correct answer for this question is '4' because there are four main ways to save a document: clicking on the save icon, using the keyboard shortcut Ctrl + S, going to the File menu and selecting Save, or using the Save As option to save the document with a different name or in a different location. These are the most common and widely used methods for saving documents in various software applications.

The correct answer for this question is 'All of these' because it includes all possible hardware parts of a computer system. This option encompasses components such as the central processing unit (CPU), memory (RAM), storage devices (hard drive, SSD), input devices (keyboard, mouse), output devices (monitor, printer), and other essential hardware components that make up a computer. By selecting 'All of these,' you acknowledge the comprehensive nature of computer hardware and its various components.

The correct answer for this question is 'Bitmap' because bitmap is a common file format used to store graphics, digital photos, and scanned images. Bitmap files are typically saved with extensions such as .bmp, making it the correct choice for this question. Additionally, bitmap files are widely supported and can be easily viewed and edited on various devices and software programs.

The correct answer for this question is '4 units' because the Arithmetic Logic Unit (ALU) in a computer typically consists of four main components: the arithmetic unit, logic unit, register unit, and control unit. These four units work together to perform arithmetic and logical operations, store temporary data, and control the flow of data within the processor.

The correct answer for this question is 'Alphabetic, space bar' because the top most row of keys on a standard keyboard typically contains the alphabetic keys, which are used for typing letters. The longest key on the keyboard is the space bar, which is used to create spaces between words while typing.

The correct answer for this question is 'Both A and B' because computer systems consist of both hardware components (option A) such as the physical parts like the processor, memory, and storage devices, as well as software components (option B) such as the operating system and applications that run on the hardware. Both hardware and software are essential for a computer system to function properly, making 'Both A and B' the correct choice.
