What are the three types of cloud services? Give a brief description of each.
IaaS/HaaS (Infrastructure as a Service/ Hardware as a Service)- hardware is being loaned to you within a cloud-based environment. The provider manages virtualization, networking, storage, and servers. (you manages security and software)
PaaS (Platform as a Service)- someone else handles foundational infrastructure and platform including operating systems and databases. The provider manages runtime, middleware, operating system, and everything else included in IaaS.
SaaS (Software as a Service)- Provider manages the entire installation, setup, updates, and running of the application. Users may simply pay for the service. (Gmail & Microsoft office 365)

What are the steps of the laser printing process? Explain what each step does.
•Processing: The computer sends data to the printer such as file size and amount of pages
•Charging: A charging wire (Primary Corona) negatively charges the drum
•Exposing: The laser draws an outline of the image
•Developing: Toner is negatively charged and is applied to the “exposed” areas of the drum
•Transferring: Another charging wire (Transfer Corona) positively charges the paper, resulting in the “negative” image being transferred to the positive paper
•Fusing: A fuser uses heat and pressure to permanently merge the image to paper
•Cleaning: The drum is cleaned of excessive toner and electrical charges
What are the causes for the following issues?
- Dim image
- BIOS time & setting resets/issues
- No source
- continuous reboots
- ghost image
- toner smearing
Dim image = backlight failing
BIOS time issues = CMOS failing
No source = power supply issue (not enough power)
continuous reboots = faulty power supply
ghost image = faulty drum
toner smearing = faulty fuser (not enough heat)
Define the following:
on-demand
Measured service
rapid elasticity
resource pooling
- On-demand: This is when the cloud is being used whenever the user wants to access its data.
- Measured service: Is paying for a set amount of storage. A user would not be able to exceed the set amount of storage. If so, they will have to pay an extra fee.
- Rapid elasticity: This is having the ability to expand the availability of cloud servers in direct response to user's needs.
- Resource pooling: Gathering a large amount of computing power to split resources to services that need them instead of idle services.
