Comptia A+ 220-801 Chapter 5 Flashcards
What are Graphic Designed Workstations used for?
Graphic design workstations are used by desktop publishers in the creation of high-quality copy
consisting of professional text and graphical images.
Computers used by graphic-design artists must process a constant flow of colors and detailed shapes, the combination of which can put a strain on the CPU, RAM, and video components.
Professionals that edit multimedia material require workstations that excel in three areas: pg 239
Video enhancements
Specialized audio
Specialized drives
To improve video-editing performance, insist on a graphics adapter that supports? pg 240
CUDA and OpenCL
What is CUDA? pg 240
CUDA is Nvidia’s Compute Unified Device Architecture, a parallelcomputing architecture for breaking down larger processing tasks into smaller tasks and processing them simultaneously on a GPU.
What is OpenCL? pg 240
Open Computing Language (OpenCL) is a similar, yet cross-platform, open standard. Programmers can specify high-level function calls in a programming language they are more familiar with instead of writing specific instructions for the microcode of the processor at hand.
Virtualization workstations must exceed the specifications of standard servers and workstations in two primary areas: pg 242
CPU enhancements
Maximized RAM
The following list includes some of the more important
components that are shared by the host and all guest operating systems: pg 242
CPU cycles
System memory
Drive storage space
Systemwide network bandwidth
The maximum installed RAM hinges on three primary
constraints: pg 243
The CPU’s address-bus width
The operating system’s maximum supported RAM
The motherboard’s maximum supported RAM
Their are 4 requirements that you need in order to have a good gaming PC what are they? pg 244
CPU enhancements
Video enhancements
Specialized audio
Enhanced cooling
In a HTPC how many watts should the power supply be at least?
150W
What is a Thin Client?
is any machine that divests itself of all or most
local storage and varying levels of RAM and processing power without necessarily giving up
all ability to process instructions and data.
What is one problem that can happen with Thin Clients? pg 248
Unfortunately, this leads to a single or centralized point of failure in the infrastructure that can impact
productivity to an unacceptable level. Thin clients have no offline capability, requiring constant
network connectivity.
Whats the difference between a home server and enterprise server?
Home servers tend to have equal access to the file server’s data store.
Enterprise file servers have data stores that are isolated from users that do not have permission to access them.
What is needed to make a HTPC work correctly for optimal performance?
Media streaming capabilities File sharing services Print sharing services Gigabit NIC RAID array
What is a HomeGroup? PG 249
A homegroup makes it easier to share files and printers on a home network. You can share pictures, music, videos, documents, and printers with other people in your homegroup. Other people can’t change the files that you share, unless you give them permission to do so.
