Q

video enhancement.

1

5-239

A

To enhance video editing we need Graphic adapter that supports CUDA and open CL:

CUDA, which stands for Compute Unified Device Architecture is a parallel computing platform and application programming interface, It allows software developers to use a CUDA-enabled graphics processing unit (GPU) for general purpose processing .

OpenCL: Open Computing Language is a framework for writing programs that execute across heterogeneous platforms consisting of central processing units (CPUs), graphics processing units (GPUs),

Q

specialized Audio.

5-140

A

six to eight channels audio is often require to perform a high quality.
many of today motherboards come with 5.1 or 7.1 analog audio but digital audio is preferred, that is way an add-on adapter supporting such adapter is required.

Q

specialized drives.

5-241

A

A drive is a medium that is capable of storing and reading information that is not easily removed like a disk.
the SATA 6Gbps is recommended for these applications.
for an external hard drive use an eSATA.
if these drives does not have the capacity we need we go with RAID 0
or we go with RAID 5 for fault tolerance and prevent data loss.

Q
  • Virtualization

5-241

A

virtualization is the process of creating a virtual version of something, such as a server or computer system, using software instead of hardware.

a server is an instance of a computer program that accepts and responds to requests made by another program; known as a client. Less formally, any device that runs server software could be considered a server as well. Servers are used to manage network resources. For example, a user may setup a server to control access to a network, send/receive e-mail,

Q
  • An operating system or OS

5-242

A

An operating system or OS is a software program that enables the computer hardware to communicate and operate with the computer software. Without a computer operating system, a computer and software programs would be useless. for example,
Microsoft Windows 7, Linux, Android.

Q

Maximized RAM

5-242

A

we need to decide how much RAM the guest OS will need when we are creating a virtual machine. that mean more RAM to be installed in the computer, that will have to effect three primary constraints:

  • the CPU’s address bus width.
  • the operating system maximum supported RAM.
  • the mother board maximum supported RAM

Q

4- Gaming PCs

244

A

to have a good gaming PC, four areas of enhancement must be considered:

  • CPU enhancement
  • video enhancement.
  • specialized audio.
  • Enhanced cooling.
17
Q

CPU enhancement

5-244

A

overclocking

18
Q

video enhancement.

5-245

A

video gaming has gone from text and simple two dimensional graphics into high complex software that required real time high resolution and high definition rendering to three dimensional modeling. using technology like Nvidia’s SLI and ATI.

19
Q
  • Nvidia’s SLI

The RAM installed ion graphics adapters has raised from MB of RAM into the GB

5-245

A

Founded January 1993, NVIDIA is one of the leading chipset manufacturers for high end video cards.

SLI- Short for Scalable Link Interface, SLI is an NVIDIA technology that allows two video cards that support SLI, to share the workload, it allow such users to combine preferably identical graphics adapters in appropriately spaced PCIe x16 slots with a hardware bridge to form a single virtual graphics adapter, increasing the overall performance. SLI video cards run on certified motherboards over PCI Express.

20
Q

specialized Audio

5-245

A

S/PDIF and HDMI are two technologies that produce high quality digital audio for the gaming.

21
Q
  • S/PDIF

5-145

A

S/PDIF (Sony/Philips Digital Interface Format) is a type of digital audio interconnect used in consumer audio equipment to output audio over reasonably short distances. The signal is transmitted over either a coaxial cable with RCA connectors or a fibre optic cable with TOSLINK connectors. S/PDIF interconnects components in home theatres and other digital high fidelity systems.

22
Q

enhanced cooling

5-245

A

when two or more adapter are add in to a gaming PC more is generated that is way today high -end graphic adapter come with there own cooling mechanism.

23
Q

5- Home Theater PCs (HTPCs)

5-246

A
  • video enhancement.
  • specialized audio.
  • special chassis.
  • TV tuner requirement.
24
Q

6- Standard thick clients

5-248

A

each operating system required a minimum set of hardware to support its instigation and each additional desktop application installed required its own set of features.

25
Q
  • thick clients

5-248

A

A thick client is a computer that does not require a connection to a server system to run (unlike a thin client), although they can benefit from being connected to a network and a server. Thick clients are often found in the business environment, where servers are used to provide some data and application support, but the thick client (office computer) is largely independent. Thick clients have their own operating system and software applications and can be used offline (not connected to a network or server).
Thick clients have several advantages including being able to be used offline, improve performance for multimedia applications (including video games), increased flexibility and higher server capacity (less of a load on a thick client server, allowing for support of more users).

26
Q
  • Thin clients

5-248

A

Alternatively referred to as a diskless node, dummy terminal, or dumb terminal, a diskless workstation is a networked computer that provides no local hard disk storage. These terminals have a monitor, motherboard, network card, keyboard, and mouse. This term can also be used to describe any computer that has a hard drive, but is booting and using applications from the network instead of from the local hard drive. This type of computer is often referred to as a hybrid computer or network computer.

27
Q
  • Home server PCs

5-249

A

A home server is a computer that functions as a server in a client-server home network. For small networks, a personal computer works perfectly well for this purpose, provided there is sufficient storage space on the hard drive, and provided there is sufficient memory.

28
Q

Home server PCs

5-249

A

is the center of the home network

29
Q
  • fault tolerance

5-249

A

A fault tolerance is a setup or configuration that prevent a computer or network device from failing in the event of an unexpected problem or error. To make a computer or network fault tolerant requires that the user or company to think how a computer or network device may fail and take steps that help prevent that type of failure.
