The correct answer is '1944' because this was the year when the first electro-mechanic computer, known as the Harvard Mark I, was completed. This computer was developed by Howard Aiken and his team at Harvard University, and it was one of the earliest programmable computers in history.

The correct answer is 'A. 400' because the maximum scale percentage available in the scale drop down box in MS Word is 400%. This means that you can enlarge the size of your document or image up to four times its original size using the scale feature in MS Word. Any percentage higher than 400% would not be available in the scale drop down box.

The correct answer is 'A. CTRLD' because pressing CTRL + D is the shortcut key used to fill down in programs like Microsoft Excel. This shortcut copies the content from the cell above and fills it down into the selected cells, making it a quick and efficient way to populate data in a column.

The correct answer is 'A. Mainframe computers' because mainframe computers are specifically designed to handle large amounts of data and multiple users simultaneously. They are commonly used in organizations like insurance companies and banks where many people need access to the same data. Mainframes are able to efficiently process and store vast amounts of information, making them ideal for these types of environments.

The correct answer is 'A. Program Counter' because the Program Counter is a register that stores the memory address of the next instruction to be executed by the CPU. It keeps track of the location in memory where the CPU should fetch the next instruction from, allowing the CPU to execute instructions in the correct sequence.

The correct answer for this question is 'Secondary' because USB storage devices are considered secondary storage devices, which are used to store data for long-term use. Secondary storage devices are external to the computer and are used to store data that is not currently being accessed by the computer's central processing unit (CPU).

The correct answer for this question is 'Vacuum Tubes and Valves' because these components were indeed the chief components used in first generation computers. Vacuum tubes and valves were used to perform the basic functions of processing and storing data in early computers. They were eventually replaced by transistors in later generations of computers.

The correct answer is '1956 to 1965' because this time period aligns with the development and advancement of second generation computers. During this period, transistors replaced vacuum tubes, leading to smaller, faster, and more reliable computers. This technological shift marked the transition from first generation to second generation computers.

The correct answer is 'A. 8 bits' because a byte is a unit of digital information that consists of 8 bits. Each bit can represent a binary value of either 0 or 1, and when combined together in a byte, they can represent a wider range of values from 0 to 255. Therefore, 1 byte is equal to 8 bits.

The correct answer is 'A. CtrlF7' because in Inpage, pressing CtrlF7 opens the Title Text box. This shortcut allows users to quickly access and edit the title text without having to navigate through menus or options. Therefore, CtrlF7 is the correct option for accessing the Title Text box in Inpage.
