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.
