What is the main circuit board inside a tablet called?
Battery
Motherboard
GPU
CPU
The motherboard is the primary printed circuit board that houses the CPU, memory modules, and other essential electronic components. It interconnects all internal devices. Without the motherboard, individual components cannot communicate.
Which component temporarily holds data for quick access by the processor?
RAM
ROM
HDD
Flash Memory
RAM (Random Access Memory) provides fast, volatile storage used by the CPU to hold data and instructions currently in use. When power is removed, the contents of RAM are lost. It differs from ROM or flash, which are non-volatile.
Which touchscreen technology is most commonly used in modern tablets?
Resistive
Infrared
Surface Acoustic Wave
Capacitive
Capacitive touchscreens detect touch through changes in an electrical field and support multi-touch. They are more durable and provide better clarity than resistive screens, which rely on pressure.
What type of battery is predominantly used in tablets due to its high energy density?
Lead-Acid
Alkaline
Lithium-Ion
Nickel-Cadmium
Lithium-Ion batteries offer high energy density, a relatively light weight, and no memory effect, making them ideal for portable devices like tablets. Other types are heavier or have lower cycle life.
Which wireless connectivity technology allows tablets to connect to local area networks?
Wi-Fi
Bluetooth
NFC
GPS
Wi-Fi (Wireless Fidelity) is the standard for wireless local area networking, enabling tablets to access the internet and share data over short to medium distances. Bluetooth is for short-range device pairing, NFC is very short range, and GPS is for location.
What is the primary function of a tablet's CPU?
Render graphics
Execute instructions
Manage power
Store files
The CPU (Central Processing Unit) executes the instructions of software programs by performing arithmetic, logic, control, and input/output operations. Rendering graphics is primarily the GPU's job, while storage and power management are handled by other components.
How does increasing RAM capacity improve tablet performance?
Charges the battery faster
Improves display resolution
Increases storage capacity
Allows more simultaneous tasks
More RAM enables a tablet to keep more applications and data in fast-access memory, reducing reliance on slower storage swapping. This allows smoother multitasking and faster app switching.
What is the main advantage of OLED displays over traditional LCD displays?
No backlight needed
Lower cost
Higher power consumption
Better sunlight visibility
OLED (Organic Light Emitting Diode) displays are self-emissive, meaning each pixel generates its own light, eliminating the need for a separate backlight and enabling deeper blacks and thinner panels.
What distinguishes capacitive touchscreens from resistive touchscreens?
Use pressure detection
Glow when touched
Rely on infrared light
Detect changes in electrical field
Capacitive touchscreens detect touch by sensing changes in the electrical field caused by a conductive object such as a finger. Resistive screens require physical pressure to register input.
If a tablet fails to power on, which hardware issue should you check first?
Camera module connection
Wi-Fi module status
Battery charge level
Screen brightness setting
A depleted or malfunctioning battery is the most common hardware reason for a tablet not powering on. Confirming the charge level and verifying the charging circuitry are the first troubleshooting steps.
Which component manages the battery charging process in a tablet?
GPU
DC-DC converter
Voltage regulator circuit
Touch controller
The voltage regulator circuit controls the flow of current to the battery, ensuring it charges at the correct voltage and current. It prevents overcharging and regulates power delivery.
NFC functionality in tablets is primarily used for:
Video streaming
High-speed internet access
Near-field data exchange
Long-range wireless communication
NFC (Near Field Communication) enables short-range communication (a few centimeters) between compatible devices for tasks like contactless payments or quick data pairing.
Which sensor in a tablet helps determine its orientation and rotational movement?
Proximity sensor
Ambient light sensor
Gyroscope
Magnetometer
A gyroscope measures angular velocity, allowing the tablet to detect rotation and orientation changes. The accelerometer measures linear motion, while the magnetometer senses magnetic fields.
Which storage type in tablets has no moving parts and retains data without power?
Optical drive
Flash memory
HDD
RAM
Flash memory uses non-volatile NAND cells to store data and retains information without power. Hard drives have spinning platters, and RAM is volatile.
What power management technique reduces a tablet's CPU speed to extend battery life?
CPU locking
CPU throttling
Thermal throttling
Overclocking
CPU throttling lowers the processor's clock speed under low-power or high-temperature conditions to conserve battery life and reduce heat output. Overclocking is the opposite, increasing speed.
When diagnosing a tablet with graphical glitches on the screen, which component is most likely at fault?
Battery
RAM
Speaker
GPU
Graphical glitches such as artifacting or stuttering are often caused by a failing or overheated GPU (Graphics Processing Unit), which renders images and video. RAM issues typically cause crashes rather than visual artifacts.
In tablet display specifications, PPI stands for:
Processor performance indicator
Picture performance index
Pixels per inch
Power per interface
PPI (Pixels Per Inch) measures the pixel density of a display, indicating how many pixels are packed into one inch of screen. Higher PPI values yield sharper images.
A tablet screen exhibits erratic ghost touches even when it's not being used. Which hardware step is best to troubleshoot?
Calibrate touch in software settings
Reboot the operating system
Check and reseat the digitizer cable
Clean the screen with alcohol
Ghost touches often result from a loose or damaged digitizer connection. Reseating or replacing the digitizer cable can resolve erratic input. Software calibration won't fix a hardware connection issue.
After 500 full charge cycles, a tablet's lithium-ion battery shows noticeably reduced capacity. This phenomenon is called:
Thermal runaway
Voltage sag
Battery aging
Memory effect
Li-ion batteries degrade over time due to chemical changes, leading to reduced capacity - a process known as battery aging. Memory effect is associated with NiCd batteries, and thermal runaway is a safety hazard.
What material is commonly used as an electromagnetic interference (EMI) shielding layer inside tablet casings?
Rubber grommet
Plastic
Copper foil
Glass panel
Copper foil is a conductive material used inside device casings to block and redirect electromagnetic interference, protecting sensitive circuits. Non-conductive materials like plastic or rubber offer no EMI shielding.
