Computer application foundation question bank and answerThe following are some examples of basic computer application questions and answers:
** 1. Single choice question **
1. In 1946, the first electronic digital computer successfully developed in the United States was called ENIAC.
2. The types of computers that did not belong to the classification of data processing methods were general-purpose computers. According to the data processing methods, they could be divided into electronic logic computers, electronic simulation computers, and mixed-model computers.
3. The computer could automatically control the process because of the stored program.
4. In the field of computing, raw data was just the basic material.
5. " Computer Aided Design."
6. In a computer, one digit of the value in the literal code takes up one bit.
7. The information in a computer was represented in a binary-format mainly because the required physical components were the simplest.
8. The components that make up the physical body of a computer are called computer hardware.
9. The maximum number of digits a computer can process at a time is called the word length of the machine.
10. In Excel, when entering numbers as text, the leading character that needed to be entered was a single quote.
11. In a cell on an excel sheet, if you want to enter the calculation formula 200 - 5, the correct input is =200 - 5.
12. The numbers used to number the rows on the electronic sheet were numbers.
13. When entering a formula or function into a cell, the leading character must be =.
14. In PowerPoint, the shortcut key to stop the slide show was Esc.
15. The following statement about computer viruses is correct. There are conditions for a computer virus to attack.
** 2. Multiple choice questions **
1. The effective way to prevent viruses was to try not to use USB drives of unknown origin; when using someone else's USB drive, first use anti-virus software to kill the virus; when someone else wanted to copy something on their own USB drive, first set their own USB drive to read-only.
2. The steps to create an Excel chart include selecting the chart type, setting the chart source data, and setting the chart options.
3. In Excel, right-clicking on a sheet's tab could insert a sheet, delete a sheet, or even renamed a sheet.
4. The slide master setting could unify the style of the entire set of slide, unify the title of the slide, unify the header and footers, and unify the type of the text.
5. The "Hyperlink" function in PowerPoint allowed you to browse a website, open other files with the corresponding software, show another slide of the manuscript, and show other manuscripts.
6. The basic attributes of computer system security are confidentiality, usefulness, and integrity.
** 3. True or False Questions **
1. In an Excel chart, the type of chart that could reflect the trend of data changes was a line chart, which was correct.
2. A trojan-horse was a malicious remote control software, but it was not purely for the purpose of destroying the computer, so the original statement was wrong.
3. In PowerPoint, the types of slide masters were slide master, notes master, and lecture master. This statement was correct.
4. A computer virus was not a destructive instruction, but a program code. The original statement was wrong.

Computer application foundation form test 1If you want to ask about the specific content of the 24th National Open University's "Computer application foundation" form test assignment 1, the following is a summary of some common knowledge points:
* * 1. Operations related to windows **
1. * * The screen is copied to the whiteboard **
- In the windows operating environment, the key to copy the entire screen to the whiteboard was Print Screen.
2. * * Moving window **
- To move the window, move the mouse pointer to the window's title bar and drag it.
3. * * Arrange desktop icons **
- In windows, the first step to arranging the desktop item icons was to right-click on an empty area on the desktop.
4. * * Search for files **
- In order to find all files with names beginning with the letter "A" in the windows, you should type A * in the Find Name box.
* * 2. Computer hardware and system related **
1. * * Computer hardware composition **
- The hardware system of a computer was composed of five parts: arithmetic unit, controller, memory, and I/O device. Language processing did not belong to these five parts.
2. * * Computer Development History **
- The first electronic computer was successfully developed in the United States in 1946, and its English name was ENIAC. The current computers were generally considered to be the fourth generation of computers, and the logic components used were large-scale integrated circuits.
3. * * Number System Conversion **
- The decimal number corresponding to the number 10110001 should be 177. The calculation method is [1,1,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2
4. * * Storage capacity conversion **
- 8 bits contained 64 bits, because 1 bit was equal to 8 bits, so 8 bits were <<8>= 64>.
* * 3. Computer software related (System software and application software are not mentioned in detail here, but the general concepts are as follows)**
1. * * Software classification **
- Computer software was divided into two categories: system software and application software. System software included operating systems, compilation programs, fault diagnosis programs, and so on. Office software belonged to application software.
