A. Steps Down Voltage
B. Increases Voltage
C. Converts AC to DC
D. Converts DC to AC
A. Steps Down Voltage
C. Converts AC to DC
What is the Reason for different color wires on a Power Supply?

You are reconfiguring a Cloud VM with additional vCPUs and additional RAM. What term best describes your actions?
A. Scaling DOWN
B. Scaling IN
C. Scaling UP
D. Scaling OUT
C. Scaling UP
Vertical Scaling means increasing or decreasing underlying VM compute power. Increasing vCPUs and RAM is called Scaling UP, whereas Decreasing is called Scaling DOWN. Scaling OUT means adding additional VMs to handle an IT workload, whereas Scaling IN means removing VMs when the workload lightens.
Three-Step Process for Data Flowing through a computer?
Step 1 Input - The computer accepts incoming data. Could be user clicking a mouse, typing something, starting a program that loads instructions.
Step 2 Processing - Computer performs Operations (Math) on data to transform it.
Step 3 Output - The RESULT of the calculation is delivered to the appropriate recipient. The result might go back to an application that requested it, and the application might then display the result on a screen or print it on paper.
The basic measurement of a CPU is?
Speed
How many things can it do in one second under perfect conditions. Each thing is a Cycle, and one Cycle per second is expressed as 1 hertz (Hz). (Hz, MHz, GHz)
What is the Difference between MHz/GHz and MB/GB?
MHz/GHz are CPU Speed measurements while MB/GB are Storage Capacity measurements.
Passive Cooling?
Passive Cooling does not use Power or Mechanical Parts, meaning it can’t keep hotter components cool. The most Common Type uses a Heat Sink - which is a block of Heat Conductive metal such as aluminum affixed to a chip with some heat-conductive thermal paste. Heat wicks away from the chip into the heat sink and dissipates into the air.
Active Cooling?
Active Cooling uses electrically powered mechanical parts. Most PC’s, a Fan is strapped to the CPU’s heat sink in an attempt to circulate the air through the heat sink and away from the CPU to keep it cool.
Liquid Cooling?
Combining Liquids with Electronics is normally a recipe for disaster because liquids conduct electricity efficiently and cause short-circuiting. Some high-end gamers and enthusiasts run that risk and use liquid cooling systems for effective active cooling. Liquid Cooling is a more efficient conductor of heat than air. Liquid cooling systems attach heat sinks (sometimes called water blocks) to each of the chips that get hot in the PC, including the CPU and key chips on the motherboard. The liquid flows through sealed tubing and channels inside the heat sinks, so it doesn’t directly touch any of the electronics. A pump circulates liquid from the reservoir through the tubing from hot chip to hot chip. As the liquid reaches a chip, it picks up some of the heat from the chip and carries it back to the reservoir.
Acronym: ROM?
Read-Only Memory
ROM stores important pieces of information for how the computer works. ROM is NON-Volatile, so it Retains the information when the Power goes Off.
Acronym: DIMM?
Dual Inline Memory Modules (RAM)
Acronym: DDR?
Double Data Rate (RAM)
Single Data Rate (SDR) is now mostly obsolete. DDR is now how RAM DIMM modules measure speed. There is DDR2, 3, 4, and 5 now.
Motherboard?
Everything in a computer plugs directly or indirectly into the motherboard. The motherboard is an essential component in the Computing Process. It provides pathways (buses) between the memory slots, CPU socket, input and output ports, and built-in devices like Network Adapters and Sound Adapters. The motherboard has its own intelligent controller (The Chipset) that manages the traffic and tells the various buses how fast they can run.
Motherboard Form Factors?
ATX (Full Size Motherboard for Large Desktops
microATX (For smaller systems)
Mini-ITX (Tiny motherboard for even smaller or specialty systems)
Acronym: PSU?
Power Supply Unit
In a Desktop PC is a big metal box mounted in one corner of the case. Has a bouquet of multicolored wire bundles coming out of it; these wires and connectors provide power to multiple individual components inside the case, including the motherboard and the disk drives. Power Supply converts the Alternating Current (AC) power from the wall outlet to the Direct Current (DC) power that computer components require, and it steps down the voltage of the incoming power to the exact amounts that each component requires.
