PC Hardware Basics
What is the main function of the CPU?
process instructions and perform calculations
This is one of the first items to consider when building a computer.
motherboard (mobo)
This traditional storage device has spinning platters
HDD (Hard Disk Drive)
What does Wi-Fi stand for?
Wireless Fidelity
Which are the two major chipset and processor manufacturers for desktop and laptop computers? (pick two)
Intel & AMD (Advanced Micro Devices)
What is overclocking?
running a processor, memory, motherboard or video card at higher speed than recommended.
What does BIOS stand for?
Basic Input/Output System
This storage device has no moving parts and is faster
SSD (Solid State Drive)
This device allows computers to connect wirelessly to a network.
Wi-Fi adapter or NIC
Zero insertion force (ZIF) sockets are used to lift the processor up and out of the socket, using levers.
True or False?
True
This component holds data temporarily for active processes.
RAM (Random Access Memory)
This newer firmware replaced BIOS in modern computers.
UEFI
Which storage type uses flash memory?
SSD
What does an IP address identify?
a device on a network
Draws heat away from the CPU.
Heat Sink
A technician needs to replace a faulty display. Which two steps will help the technician complete the task in a timely and efficient manner?
1. document and label screws and cables location
2. organize all parts.
Mention one good reason to flash the BIOS/UEFI?
- system hangs at odd times
-some mobo functions have stopped working
-incorporate new components
-get errors when trying to install OS
True or False: SSDs are more durable than HDDs.
True
This term describes the speed at which data is transmitted.
Bandwith
Today's processor architectures fall into two categories:
Hybrid processors – known as x86-64 processors
64-bit processors – known as x64 processors or IA64
Name 2 devices considered "black boxes" and should never be opened.
Monitor and Power Supply
Name one key difference between BIOS and UEFI.
BIOS supports drivers up to 2.2 TB / UEFI supports drivers more than 2.2 TB and graphical interface.
BIOS 16 bits / UEFI 32-64 bits
BIOS text based, keyboard only / UEFI graphical interface
BIOS slower boosts / UEFI Faster boots
This interface is commonly used to connect storage drives.
SATA or NVMe
What is the most common Wi-Fi frequency band?
2.4 GHz or 5 GHz
Processor designed for entry-level desktops and laptops:
Pentium or Celeron
