MANAGEMENT REVIEW QUESTIONS ANSWERS
VERIFIED GUIDE
◉ Cloud Computing.
Answer: Delivering of computing services over the internet rather
than hardware
◉ Digital Data.
Answer: Binary Data
◉ Analog Data.
Answer: Physical Data, sound waves, continuous data
◉ Compression.
Answer: Reduction of file size by eliminating redundant data (Zip,
gz, pkg)
◉ Lossy.
Answer: Throws away some data (JPEG, MP3)
◉ Lossless.
,Answer: Compression reduces file size without any permanent loss
of data (Zip, PNG)
◉ Pixel Interpolation.
Answer: The process of estimating New Pixel
◉ Information.
Answer: Data is raw facts, unorganized facts and figures, while
information is processed data with meaning
◉ Bitmap.
Answer: Composed of pixels, graph, and pixel-assigned color, more
realistic, gets pixelated when resizing
◉ Vector Graphics.
Answer: Use mathematical formulas to define shapes and lines, less
storage, very easy to edit, don't lose quality on resizing

Answer: 2D images that look 3D
◉ Vectors.
Answer: Form wireframe, representations of 3D objects
,◉ Rendering.
Answer: Covering wireframe with color and texture
◉ Ray Tracing.
Answer: Adding light and shadows
◉ Software.
Answer: Programs that control hardware and perform tasks, set of
instructions, data, or programs that tell a computer or electronic
device what to do
◉ Application.
Answer: Set of programs (like Word or Excel)
◉ Operating.
Answer: Manages hardware & runs applications (like Windows)
◉ Magnetic.
Answer: Foundation for hard drive, magnetic micro particles on
surface
, ◉ Optical.
Answer: CDs & DVDs (use light + dark spots) drive has a lazer
◉ Solid State.
Answer: Flash Memory, data can be erased, (SSDs, USB drives)
◉ Cloud.
Answer: Remote Storage accessed through the internet
◉ CPU.
Answer: Central Processing Unit, processes instructions
◉ ALU.
Answer: Arithmetic Logic Unit, handles operations/uses registers to
mold data, maths
◉ Control Unit.
Answer: Microprocessor, fetches each instruction, tells everything
what to do
◉ RAM.
