Hardware 2 Flashcards
Where could you install a PCI X2 card?
In a PCI X4 expansion slot, according to some it could also work with a X1 expansion slot but it depends on the manufacturer.
You are trying to start a system from a bootable DVD, but the system always boots to the hard drive instead. What should you do?
Manipulate the start sequence in the BIOS.
After trying to run a virtualization software, you realize that the BIOS doesn’t support virtualization. What should you do?
Flash the BIOS.
What two components determine the speed of the bus?
Crystal frequency / bit size and multiplier.
What does DRAM do?
Dynamic refers to how bits are stored in an electrical component called a capacitor.
What is a DIMM?
Dual in line memory module. Is a circuit board that holds memory chips.
What is SODIMM?
Small outline dual in line memory module are smaller chips and are used in smaller devices e.g laptops, computers and printers.
How many bits can a dual channel access at a time?
128 bits
How many bits can a triple channel access at a time?
192 bits
What is the difference between single sided and double sided RAM?
In double sided RAM, the RAM is separated into two groups known as ranks and the system can only access one rank at a time. If it needs to access the other rank it needs to switch to the other RAM. Single sided RAM or single rank is in a single group and the system can access all RAM on the DIMM without switching.
What is RAM parity checking?
It is the storing of a redundant parity bit of a small amount of computer data stored in RAM and the comparison of the stored and computed parity to detect whether a data error has occurred.
What is ECC RAM?
ECC RAM uses additional circuitry and can detect and correct errors. This adds significantly to the cost of RAM and should be purchased only when necessary.
How do you check how many cores your CPU has?
CTRL + SHIFT + ESC and then clock the performance tab, count the number of boxes under CPU usage history.
Where is hyper threading enabled?
In the BIOS
What is AMD HyperTransport (HT)?
Not the same as hyper threading instead it involves increasing the bandwidth or the amount of data transferred per second across a specific 32 bit bus.
What is the difference between a CPU cache and a web browser cache?
The CPU cache is RAM and the web browser cache is stored as a file on a hard drive.
How can you increase CPU speed?
Increasing the clock frequency, increasing the multiplier or both known as over-clocking. In some systems the BIOS has a cell menu that. Enables you to increase the base frequency and increase the CPU Ratio (multiplier).
What is a virtualization software?
It allows you to run multiple virtual machines (VT) as a guest within a single physical host computer. Enabled in the BIOS.
What are 2 dedicated graphics slots?
AGP and PCIe slots( North bridge)
What is a GPU?
Newer CPUs include and integrated Graphics processing unit on the CPU. ( GPUs provide high quality graphics without the additional cost of a graphics card)
What is a ZIF?
Zero Insertion Force socket. To eliminate pins (in PGA) from breaking manufacturers came up with a ZIF socket. It has a locking lever where you can place any CPU into the socket without any force other than gravity and after the CPU is in place you can lock the lever to secure it.
What are some motherboard form factors?
Physical appearance, air flow, power connectors and basic layout
What is an example for a Mini - ITX
Home theatres (HT)
How much is 1 MHZ?
A million cycles per second
