IT Foundations (CompTIA A+) Flashcards
What will cause incorrect system dates and loss of bios settings
dying CMOS battery
what manages I/O interfaces for the computer such as PCI, PCIe, USB, serial, and IDE?
this was developed to replace PC Card PCMCIA and is used in laptops - provides additional connection ports for PCs
Resides on the motherboard and is brown in color, used for connecting a video card to a computer
this CPU component performs arithmetic and logic operations
arithmetic logic unit
this CPU component fetches instructions from memory, decodes, and executes them
a UEFI feature that verifies an operating system’s boot loader is electronically signed by the vendor before it loads
an international standard designed to secure hardware by integrating encryption keys into devices. Use RSA keys for hardware authentication and used by DoD
Trusted Platform Module
allows the operating system to control the amount of power given to each device and to power them down when not in use
Advanced Configuration Power Interface
enables the computer to discover and configure new hardware, and manage any hardware conflicts that arise when new hardware is added.
The computer accesses these while the firmware is in control of computer
The computer accesses these while the OS is in control of computer
through what does the RAM connect to Northbridge or CPU itself?
memory controller on the chip and the memory bus on the motherboard
have additional circuits that hold data and manage electrical signals before the information is passed between RAM and the memory controller
based on the memory bus’ clock signal to synchronize thwith the system bus clock speed
Double Data Rate memory
which is smaller DIMM or SODIMM
