Tcubillos - Eighth Grade ICT Semester Test

The correct answer is Central Processing Unit. The CPU is the primary component of a computer that performs most of the processing inside the computer. It is responsible for executing instructions, performing calculations, and managing the flow of data between different parts of the computer.

The formula bar in a spreadsheet program like Microsoft Excel displays both the formulas and the data that are present in the active cell. This allows users to view and edit the formulas that are used to calculate the values in the cell, as well as see the actual data that is stored in the cell. It provides a convenient way to review and modify the calculations and data in a spreadsheet.

The correct answer is "light, portable and portable PC." This answer accurately describes a laptop computer, as it is a small and lightweight device that can be easily carried around. It is also referred to as a portable PC because it can be used anywhere, making it convenient for users who need to work or access information on the go.

The correct answer is 2007 because it is stated that the Microsoft Excel version in the ICT classroom is 2007.

The CPU (Central Processing Unit) is often referred to as the brain of the computer because it is responsible for executing instructions and performing calculations. Similar to how the brain is the central control unit of the human body, the CPU is the central control unit of the computer. It processes data, performs calculations, and manages the flow of information between different components. Without the CPU, a computer would not be able to function properly, just as the human body cannot function without a brain.

To make a column wider, you can place the mouse on the border of the column and drag it to the desired size. This action allows you to manually adjust the width of the column according to your preference.

A cell in Microsoft Excel is a rectangular box identified by a unique letter-number combination where you can enter and store information such as text, numbers, or formulas. Cells are the basic building blocks of a worksheet and are used to organize and manipulate data. The other options listed (Sheet tab, Name Box, Formula bar) are different elements or features within Excel, but they do not refer specifically to the rectangular box where you can type information.

The correct answer is CD and DVD drive because an optical drive is a device that uses laser light or electromagnetic waves to read or write data on optical discs such as CDs and DVDs. It is not related to floppy disk drives, hard disk drives, or zip drives.

The correct answer is "Personal digital Assistant" because a PDA is a type of personal computer that is designed to be portable and provide functions such as organizing schedules, managing contacts, and accessing the internet. It is typically small in size and can fit in the palm of one's hand, making it convenient for personal use. The term "personal digital assistant" accurately describes the purpose and functionality of a PDA.

The fan inside the computer is used to keep cool the computer by circulating air and dissipating heat generated by the components. This is important as excessive heat can cause damage to the computer's hardware and affect its performance.

Mainframe computers are large and powerful machines that are capable of handling a high volume of data processing and storage. Due to their capacity and capability, they are commonly used by large businesses, universities, and government offices. Large businesses often require extensive computing power to handle their complex operations, universities need them for research and academic purposes, and government offices rely on mainframes for managing vast amounts of data and running critical applications. Therefore, all of the options mentioned - large businesses, universities, and government offices - are correct in terms of using mainframe computers.

Early PCs were quite unlike the PCs that we all use today because they had monitors that only displayed text, they did not have hard drives, and they did not have a mouse. This means that early PCs were limited in terms of their display capabilities, storage capacity, and input methods compared to modern PCs.

Ultramobile PC refers to palmtop computers, which are small and lightweight devices that can be easily carried in a pocket or handbag. These computers are designed to provide mobility and convenience, allowing users to access their files, browse the internet, and perform basic computing tasks on the go. Unlike desktop computers and mainframes, which are larger and not easily portable, and laptop computers, which are larger and bulkier than palmtop computers, ultramobile PCs are specifically designed for portability and ease of use.

ROM stands for Read Only Memory. Read Only Memory is a type of computer memory that is non-volatile and can only be read from, not written to. It contains permanent instructions that are programmed during manufacturing and cannot be changed or erased by normal computer operations. This type of memory is used to store firmware, which is essential for booting up the computer and running basic functions.

Microsoft Excel is a spreadsheet program that is primarily used for organizing and analyzing data. One of its features is the ability to have a large number of rows and columns. However, in Excel, the number of rows is typically greater than the number of columns. This is because Excel is designed to accommodate a large amount of data in a vertical format, with rows representing individual records or data points, while columns are used to categorize or label the data. Therefore, the statement "more rows than columns" accurately describes the layout of Excel.
