_________________ holds data and instructions temporarily
Correct Answer
B. RAM
Explanation
RAM, or Random Access Memory, is a type of computer memory that holds data and instructions temporarily while the computer is running. It is a volatile memory, meaning that its contents are lost when the power is turned off or the computer is restarted. RAM is used by the computer to store data that is currently being processed or used by the CPU, as well as instructions that need to be executed. It allows for quick access and retrieval of data, making it an essential component for the smooth functioning of a computer system.

___________________ holds data and instructions necessary for starting up the computer
Correct Answer
A. ROM
Explanation
ROM stands for Read-Only Memory. It is a type of computer memory that holds data and instructions necessary for starting up the computer. Unlike RAM (Random Access Memory) which is volatile and can be written to, ROM is non-volatile and cannot be modified or erased. It contains firmware or software that is permanently stored and cannot be changed by normal computer operations. Therefore, ROM is the correct answer as it is specifically designed to hold the essential startup information for the computer.
3.
Which of the following is NOT a disadvantage of a RAM chip?
Correct Answer
D. It is non-volatile
Explanation
RAM stands for Random Access Memory, and it is a type of computer memory that is volatile, meaning it loses its stored data when the power is turned off. This is a disadvantage because it means that any data stored in RAM will be lost if the computer loses power. Additionally, RAM has limited storage capacity, so it can only hold a certain amount of data at a time. Lastly, RAM can be expensive, especially when compared to other types of memory. However, the statement "It is non-volatile" is not a disadvantage of RAM because RAM is actually volatile, not non-volatile.
4.
Which of the following is dvantage of a RAM chip?
Correct Answer
B. It is non-volatile
Explanation
The correct answer is "It is non-volatile." This means that the data stored in a RAM chip is not lost when power is turned off. Unlike volatile memory, which loses its data when power is removed, non-volatile memory retains its data even without power. This is advantageous because it allows for quick and easy access to data without the need for constant power supply or data backup.
5.
PROM is a type of __________________chip?
Correct Answer
B. ROM
Explanation
ROM stands for Read-Only Memory, which is a type of chip that retains its stored data even when the power is turned off. Unlike RAM (Random Access Memory), which is volatile and loses its data when the power is removed, ROM is non-volatile and its contents cannot be modified or erased. Therefore, ROM is the correct answer as it accurately represents the type of chip that PROM is.
6.
RAM means _______________________
Correct Answer
RANDOM ACCESS MEMORY
Explanation
RAM stands for "Random Access Memory." However, in this case, the given correct answer states that RAM means "READ ONLY MEMORY," which is incorrect. Read-only memory (ROM) is a type of computer memory that stores data permanently and cannot be modified or erased. On the other hand, RAM is a type of computer memory that is used for temporary storage of data that can be read from and written to by the computer's processor. Therefore, the given correct answer is incorrect, and the actual meaning of RAM is "Random Access Memory."
7.
ROM means ____________________
Correct Answer
READ ONLY MEMORY
Explanation
ROM stands for Read Only Memory. It is a type of computer memory that stores data permanently and cannot be modified or erased by normal computer operations. It contains instructions that are permanently written during manufacturing and retains its data even when the computer is turned off. ROM is used to store firmware, which is essential for booting up the computer and running basic functions. It is called Read Only Memory because the data stored in it can only be read and not written or modified.

__________________ is used to identify the columns on a spreadsheet?
Correct Answer
LETTERS
LETTER
Explanation
The correct answer is LETTERS. In a spreadsheet, columns are typically identified using letters. Each column is assigned a unique letter to distinguish it from other columns. This letter is used as a reference when performing calculations or organizing data in the spreadsheet. The answer LETTER is incorrect as it does not accurately describe the method of identifying columns in a spreadsheet.
9.
What is used to identify the rows on a spreadsheet?
Correct Answer
NUMBERS
NUMBER
Explanation
In a spreadsheet, rows are typically identified by numbers. Each row is assigned a unique number to distinguish it from other rows. This allows users to easily reference and manipulate specific rows within the spreadsheet. Therefore, the correct answer is "NUMBERS" and "NUMBER" as they both accurately describe the method used to identify rows on a spreadsheet.

____________________ runs from left to right
Correct Answer
ROWS
ROW
Explanation
The given question is asking for a term that runs from left to right. The options provided are "ROWS" and "ROW". Both options are related to the arrangement of data in a table. However, "ROWS" is the correct answer as it refers to multiple rows running from left to right, while "ROW" refers to a single row.
11.
____________________ runs from top to bottom
Correct Answer
COLUMNS
COLUMN
Explanation
The given correct answer is "COLUMNS, COLUMN" because both words can be read from top to bottom. In the first word, "COLUMNS," each letter is read vertically downwards in a column-like manner. Similarly, in the second word, "COLUMN," each letter is also read from top to bottom. Therefore, both words fit the description of running from top to bottom.
12.
____________________ is an intersection of a row and a column
Correct Answer
CELL
CELLS
Explanation
A cell is an intersection point where a row and a column meet. In the context of this question, "cell" refers to a single intersection point, while "cells" refers to multiple intersection points. Therefore, either "cell" or "cells" can be considered as an intersection of a row and a column.
13.
All formulae begins with an _________________ sign
Correct Answer
=
equal
Explanation
All formulae in mathematics and other fields typically begin with an equal sign (=). This sign is used to indicate that the expression on the left side of the equal sign is equal to the expression on the right side. It is a fundamental symbol in mathematical notation and is used to establish equations, define relationships, and solve problems.

Use the cell address F5 to answer the question . F represents _______________
Correct Answer
COLUMN
Explanation
The cell address F5 is used to answer the question and F represents the COLUMN. In spreadsheet software, such as Microsoft Excel, columns are labeled with letters, and F is one of the letters used to represent a column. Therefore, F5 refers to a specific cell in the F COLUMN.
15.
Use the cell address F5 to answer the question . 5 represents _______________
Correct Answer
ROW
Explanation
The cell address F5 represents the row number of the cell. In Excel, each cell is identified by a unique address which consists of a column letter and a row number. In this case, F5 refers to the cell in the 5th row of column F. Therefore, the correct answer is ROW.
