Topic 1
Which cable type is commonly used today to connect storage devices like SSDs and HDDs to the motherboard?
SATA (Serial ATA) cable.
Which storage device uses spinning magnetic platters to store data?
Hard Disk Drive (HDD).
What is the main purpose of the BIOS or UEFI in a computer?
To initialize hardware during startup and load the operating system.
What type of network covers a small geographical area such as a home, school, or office building?
Local Area Network (LAN).
Which type of internet connection uses telephone lines but allows users to browse and make phone calls at the same time?
DSL (Digital Subscriber Line).
What is the main function of the motherboard in a computer system?
The motherboard connects and allows communication between all computer components such as the CPU, RAM, storage devices, and expansion cards.
What is the main purpose of RAM in a computer system?
RAM temporarily stores data and instructions that the CPU is currently using so the system can access them quickly.
If a computer does not turn on at all when the power button is pressed, which internal component should be checked first?
The Power Supply Unit (PSU).
Which networking device connects multiple devices within the same network and forwards data to the correct destination based on MAC addresses?
A network switch.
What does TCP stand for, and what is its main purpose?
TCP stands for Transmission Control Protocol.
Its main purpose is to ensure reliable, ordered, and error-checked delivery of data between devices.
Which connector provides power directly from the power supply to the motherboard?
The 24-pin ATX power connector
What is the primary function of a Power Supply Unit (PSU) in a computer?
The PSU converts AC power from the wall outlet into DC power and distributes it to computer components.
What error message typically appears when the system cannot find a bootable operating system on the drive?
Operating System not found” or “No boot device found.
Which type of twisted-pair cable is commonly used in modern Ethernet networks and uses an RJ-45 connector?
Cat5e or Cat6 Ethernet cable (UTP cable)
Which protocol is used to translate a domain name like www.google.com
into an IP address?
DNS (Domain Name System).
Which legacy cable was commonly used to connect older hard drives and optical drives before SATA was introduced?
IDE (Integrated Drive Electronics) cable, also known as PATA (Parallel ATA)
What does the term “multi-core processor” mean?
A multi-core processor contains two or more independent processing units (cores) within a single CPU, allowing it to perform multiple tasks simultaneously.
If the computer powers on but there is no display and no POST beep, which component is most likely faulty?
The motherboard, RAM, or CPU (commonly RAM or motherboard failure)
What is the difference between 2.4 GHz and 5 GHz wireless frequencies?
2.4 GHz has a longer range but slower speeds and more interference, while 5 GHz offers faster speeds but shorter range and less interference.
What is the purpose of a default gateway in a network?
A default gateway allows devices on a local network to communicate with devices on other networks, including the internet.
What is the difference between PCIe x1 and PCIe x16 slots on a motherboard?
The difference is the number of lanes and bandwidth.
Why is thermal paste applied between the CPU and the heat sink?
Thermal paste fills microscopic gaps between the CPU and heat sink to improve heat transfer, preventing overheating and maintaining stable performance.
What is one major difference between BIOS and UEFI?
UEFI supports larger hard drives (over 2TB), faster boot times, secure boot, and a graphical interface, while BIOS is older, limited to smaller drives, and uses a text-based interface.
Which networking device connects different networks together and assigns IP addresses to devices in a typical home network?
A router (which often includes DHCP functionality)
What is the difference between a public IP address and a private IP address?
A public IP address is globally unique and accessible over the internet, while a private IP address is used within a local network and cannot be accessed directly from the internet.
