The base unit of the computer system houses which of the following system components 1. turn the brightness up and the contrast down a little, 2. leaving the monitor and computer switched on over the weekend improve results , 3. using a screen saver program create online tests , 4. only using text mode applications instead of graphics applications, 11. The instruction register holds a copy of the instruction which the processor is about to execute 1. check the keyboard lights to see if they flicker on power-up, 2. watch the floppy drive lights to see if they come onlisten to see if the speaker sounds on power-up, 3. check to see if the initial bios power-up message is displayed, 12. ROM is volatile 1. place the diskette next to a magnetic field, 2. write on the diskette using a soft felt pen, 3. spill coffee on the diskette e-learning , 4. eject the diskette from the drive when the drive light is on, 13. In a half duplex circuit, data may be sent in either direction 1. is the same as other models but uses slightly less power, 2. consumes less power than other models when it is powering up, 3. switches itself off into low power states when the input signal does not change for a determined time interval, 4. should only be used on more expensive computers, 14. The instruction pointer/program counter of a processor specifies the address in system memory of the data for the current instruction 1. Power Supply, 2. Floppy Drive, 3. Motherboard, 4. All of the above, 15. The Arithmetic Logic Unit (ALU) of a processor performs trigonometry functions 1. should be powered on before the computer system, 2. should be powered on after the computer system, 3. can be connected to the computer system with power already turned on, 4. should be turned off before the computer is turned off, 16. A computer system is assembled. On power-up, no screen image is displayed. Which of the following quick checks is POINTLESS (not worth doing) in determining if the computer appears to be working TRUE, FALSE, , 17.
