Chapter 5

Question 1

What do Computerized Numerical Control (CNC)’s do?

Answer 1

The take a set of coded instructions and render them into machine or tool movements. p. 239

Question 2

Professionals who edit multimedia material require workstations that excel in what three areas?

Answer 2

1) Video Enhancements p. 239
2) Specialized Audio
3) Specialized Drives

Question 3

How does Non Linear editing (NLE) Differ from linear editing?

Answer 3

NLE differs from linear editing by storing the video to be edited on a local drive instead of editing being performed in real time as teh source video is fed into the computer. NLE requires workstations with much higher RAM capacity and disk space. p.239

Question 4

To improve video editing performance what should your graphics adaptor support?

Answer 4

CUDA and Open CL. p.240

Question 5

What is the difference between CUDA and Open CL?

Answer 5

CUDA is Nvidia’s Compute Unified Device Architecture, a parallel computeting architecture for breaking down larger processing tasks into smaller tasks and processing them together on a GPU. OPEN CL is a similar, yet cross plattform open standards. THe programmers can specify high level function calls instead of writing specific instructions. CUDA is optimized for Nvidia GPU’s while Open CL is more universal less ideal when used with the Nvidia GPU’s that CUDA supports. p. 240

Question 6

In a graphics editing workstation running drive intensive NLE software what can you do to reduce the need for multitasking by a single drive?

Answer 6

You should seperate the drive that contains the operating system and the drive that contains the media files. Not only should you use separate drives for system and data files you should make sure the data drive is large and fast. SAZTA 6Gps drives that spin at 7200rpm and faster is recommended. p. 241

Question 7

Virtulization workstations must exceed the specifications of standard servers and workstations in what two primary areas?

Answer 7

1) CPU enhancements

2) Maximized RAMp.242

Question 8

When utilizing virtulizaiton, what can you do to increase the number of CPU cycles that can be assigned to each virtual machine?

Answer 8

Install more CPUs on the workstation.p. 242

Question 9

What dictates the maximum RAM you will be able to use in the workstation?

Answer 9

1) The CPU’s address-bus width
2) the operating systems maximum supported RAM
3) The motherboard’s maximum supported RAM

Question 10

What are some benefits of utilizing virtulization in a company?

Answer 10

Over time the expense of using virtulization in the company’s server is reduced by saving on energy costs and replacing machines. p. 243

Question 11

To make a PC competitive with other gaming technologies what areas of enhancement to the PC must be considered?

Answer 11

CPU enhancements
Video enhancements
Specialized audio
Enhanced cooling p.244

Question 12

What is a method of enhancing the CPU?

Answer 12

Make changes in the BIOS to have the CPU’s clock increase in speed (Overclocking). p.244

Question 13

What applications can you utilize to enhance the video quality to render three dimensional effects?

Answer 13

Nvidia’s SLI and ATI’s Crossfire. p.245

Question 14

What are some technologies that you can utilize to achieve high quality digital audio for the gaming enthusiast?

Answer 14

S/PDIF and HDMI. p.245

Question 15

If you increase the speed of the CPU’s clock by flashing the BIOS, what are some considerations to prolong the life of the CPU?

Answer 15

YOu must install enhanced cooling methods. p. 245

Question 16

List some video enhancement interfaces.

Answer 16

HDMI, DVI YpbPr, component video. p.246

Question 17

Define Standard Thick Client.

Answer 17

A standard client computer system that must meet only the basic standards that any system running a particular operating system and particular applications must meet. And attach to a network and accept a configuration that attaches it to one or more serves. p. 248

Question 18

Define Thin Client

Answer 18

Any machine that divests itself of all or most local storage and varying levesl of RAM and processing power without necessarily giving up all ability to process instrucitons and data. i.e dumb terminal . p248

Question 19

How does fault tolerance differ from redundency?

Answer 19

With fault tolerance you can access data during a failure while redundancy allows you to recover data after the failure. Redundancy in the form of a data backup does not ensure the continued accessibility but RAID seeks to do so. p.249

Question 20

When building a home PC, what are some enhanced features you should consider?

Answer 20

Media streaming capabilities
file sharing services
print sharing services
Gigabit NIC
RAID arrayp. 249

Question 21

What are some benefits of using RAID hardware?

Answer 21

The servers operating system is not taxed with the task of managing the array. The RAID array can extend to many terabytes n size and allows backup of data. p. 253-254

Question 22

What is a CRT monitor?

Answer 22

It is a high resolution monitor used for Graphics editing and gaming. p. 240

Question 23

What can you do to change analog audio into digital?

Answer 23

install an add on adaptor. p. 240

Question 24

What are some form factors of the Home theatre PC’s?

Answer 24

The Chassis is typicall 17x17x7 and 150 W power suply , the motherboard is mini ITX with intergrated HDMI video,
HDD or SSD usually 21/2 portable form factor, DIMMS for mii ITX motherboard, SODIMMS for pre built models, Blue Ray drive, PCIe or USB TV tuner card. p. 247

Question 25

Describe how to configure windows 7 for media streaming.

Answer 25

In control panel run the network and sharing cneter appplet in classiic view, click the change advanced sharing settings in the left frame, click the down arrow to the right of Home or Work to expand that configuration section, click Choose media stremaing, and choose which computers are allowed to stream from the local PC, click OK, Open Media Player, and ensure streaming works.
