CompTia A+ 2001 Module 1 Flashcards
What are the two types of passwords that can be enabled in the BIOS?
The User and Supervisor passwords.
what are user password?
The User password can be enabled and this will prevent the OS from starting.
what are supervisors password?
The Supervisor Password when enabled can prevent access to the BIOS and prevents changes from being made.
What is the TPM?
Trusted Platform Module is a chip on the motherboard that can be added or built-in
What does the TPM do?
It enables Full Disk Encryption by maintaining the encryption keys for encryption and decryption of the disk.
What is Lojack?
Lojack is a software that can be installed in the BIOS
what is Lojack used for?
track, disable, and shutdown a laptop if lost or stolen if it’s connected to the Internet.
the software automatically installs to the hard drive, so if the hard drive is removed and replaced, the software is installed again on the new hard drive thus enabling it to still be located.
What does POST stand?
POST – Power On Self-Test
what is POST used for
portion of the boot process that a computer goes through to check if its hardware components are working correctly.
What is the purpose of a POST card?
POST card connects to the motherboard of the system and visually displays the POST error code to display error codes during the POST.
What is a peripheral?
Any device that can be plugged in or connected to a computer.
What are Input Peripheral?
Input Peripherals are any of the unlimited number of devices that can plug into a computer to INPUT information into the system.
What are Output Peripherals?
Output Peripherals are any number of unlimited devices that provide output of data from a computer.
Where is the BIOS located on a system?
The BIOS chip is on the motherboard.
What is UEFI?
The Unified Extensible Firmware Interface, new generation BIOS that was implemented by Chip manufacturers can:
● Boot from large GPT disks (>2.2TB) ● Pre-boot has its own OS
● Able to connect remotely
What is a System Unit?
System unit is comprised of the CPU, hard drives, memory, motherboard, and other internal components.
What is the purpose of the CMOS?
legacy BIOS, settings were saved to CMOS so a constant power source was needed to maintain the configuration.
12.What does virtualization has to do with the BIOS of a computer?
Enabling virtualization support is simple as enabling the feature in the BIOS. By enabling this feature, the system would then support virtualization.
What is Secure Boot?
Secure boot is a security standard developed by members of the PC industry to help make sure that a device boots using only software that is trusted by the Original Equipment Manufacturer (OEM).
What is the BIOS?
BIOS is what actually “starts” your system. BIOS performs hardware checks on a computer system and starts up the OS.
What is the Boot Sequence?
The list of devices and the order in which they should be checked and be found and arranged in the CMOS setup utility.
True or False? UEFI supports Secure Boot
True. It supports Secure Boot, which means the operating system can be checked for validity to ensure no malware has tampered with the boot process.
True or False? The UEFI configurations and settings are saved to the CMOS battery.
False. Changes to the UEFI are saved to flash memory. Does not need to be saved to CMOS.
True or False? On motherboards with the newer UEFI BIOS, the date and time settings are saved to the CMOS battery.
True. In newer systems with UEFI, the CMOS battery simply keeps the date and time.
True or False? The System Unit is considered to be the computer, its internal components, and all peripherals connected to it.
False. The System unit is comprised of the CPU, hard drives, memory, motherboard, and other internal components.
The CMOS saves configurations and settings from the motherboard even in loss of power situations when its battery is removed.
False. CMOS has to have a power source to store the settings.
Which of the following form factors is the most common on the PC market?

In the PCIe bus, what is the total number of full duplex lanes that can be utilized by a device?
The total number of full-duplex lanes that can be utilized is 32 or x32.
What is the best way to determine the total capacity of RAM your motherboard is rated for?
Check with the motherboard manufacturer
USB, Audio, SATA, IDE, & CMOS Memory are all functions controlled by what chipset?
