Gaaffii 1
What does POST stand for?
Deebii: A Power On Self-Test
Sababa
POST stands for Power On Self-Test. It is part of the computer's startup program. It checks the keyboard, RAM, disk drives and other hardware to make sure they work.
Gaaffii 2
What must you do before you remove or replace any computer part?
Deebii: A Switch off the computer
Sababa
The textbook says it is necessary to switch off the computer before any hardware maintenance, such as removing or replacing computer parts.
Gaaffii 3
In Device Manager, a yellow triangle with an exclamation mark next to a device means:
Deebii: A The device has a problem
Sababa
A yellow triangle with an exclamation mark shows that the device has a problem. The other symbols mean different things: a downward arrow means disabled, a yellow question mark means the driver is unknown, and a red X means disabled, removed or not found.
Gaaffii 4
When a computer is turned on, it makes one short beep and runs fine. What does this mean?
Deebii: A The system is booting properly
Sababa
The textbook says that most computers emit one beep to show that the system is booting properly. So one short beep is a normal sign, not an error.
Gaaffii 5
A computer in an office in Addis Ababa has two RAM sticks installed. When it starts, it makes a long, continuous beep and does not boot. Which action should the technician take first?
Deebii: A Remove one RAM stick and try to boot the computer
Sababa
A long, continuous beep means the RAM sticks may have gone bad. If there is more than one stick, take one out and see if the computer boots. Then try the other stick. This shows which stick has the problem.
Gaaffii 6
A projector in a school in Hawassa is connected to a computer. When the computer starts, it gives one long beep and two short beeps. What is the problem, and what is the first action?
Deebii: A Video card failure; reseat the video card
Sababa
One long and two short beeps means there has been a video card failure. The first action is to reseat the video card. The textbook says this often solves the problem with projectors, because the video cable gets moved so often that the card can slowly unplug. If reseating does not work, replace the video card.
Gaaffii 7
There is a sudden power cut in an office in Addis Ababa. The staff need enough time to save their work before the computer turns off. Which power protection device is designed for this?
Deebii: D UPS (Uninterruptible Power Supply)
Sababa
A UPS protects against the complete absence of electricity. It is a short-term battery that keeps the computer running for 5 to 30 minutes when the power fails. This gives you time to save your data. A surge protector guards against too much electricity, a stabilizer keeps the voltage at a desired level, and a voltage regulator protects against too little electricity.
Gaaffii 8
Abebe checks his hard disk in Defragment and Optimize Drives. The drive's current status says (0% fragmented). What should he do?
Deebii: A Nothing, because there is no need to defragment
Sababa
The textbook says that if the drive's status says (0% fragmented), there is no need to do defragmentation. Abebe does not need to do anything to the drive at this time.
Gaaffii 9
A customer in Bahir Dar brings a computer that will not start properly. The customer has never made a backup. What should the technician do before doing any troubleshooting?
Deebii: B Take a backup first, and do not start troubleshooting until it is done
Sababa
The textbook says that backup is the first step before any troubleshooting. If a backup has not been taken, do not take any troubleshooting activity. Protecting the customer's data comes first.
Gaaffii 10
In the Windows Resource Monitor, a process name is shown in red. What does this colour mean?
Deebii: C The process is not responding
Sababa
In the Processes section, running processes are shown in black, suspended processes are shown in blue, and processes that are not responding are shown in red. So a red process is one that is not responding.
