What are synthetic and emulated drivers?
Q: By default is the emulated NIC installed and then you need to upgrade to a synthetic NIC?
>>> After you create a VM in Hyper-V, the default network adapter is a synthetic network adapter, however, you can't use the synthetic network adapter until you install Integration Services in this VM. If you want to perform a network-based installation( PXE boot) of the guest operating system or when integration services are not installed in the guest operating system, please use a legacy network adapter instead of the synthetic network adapter.
Q: How can you tell if you are using an emulated NIC or a synthetic NIC?
>>> You can check this in the VM's settings or you can open device manager inside the VM. The Legacy Network Adapter is an emulated adapter (Intel 21140 PCI)

- System analysis enables the user to find and fix problems that are affecting the system. System analysis scans the system in different, individual sections to determine the problem and give the user a solution and possible requirements that are needed.
- Design Techniques show the user's software features in full detail which usually enable the user to see his/her software information in different formats, which include hierarchy diagrams and layout diagrams. These different ways of viewing software information are primarily used to enable programmers to create new software without having to spend additional time with the creation of software requirement designs.

When you convert k's to m's or m's to g's then you want to round the number to the next 5th to allow for transfer of the file between different divices with different file systems
Query languages are computer languages used to make queries into databases and information systems. Broadly, query languages can be classified according to whether they are database query languages or information retrieval query languages. Examples include: * .QL is a proprietary object-oriented query language for querying relational databases; * Common Query Language (CQL) a formal language for representing queries to information retrieval systems such as as web indexes or bibliographic catalogues. * CODASYL; * D is a query language for truly relational database management systems (TRDBMS); * DMX is a query language for Data Mining models; * Datalog is a query language for deductive databases;
fat stands for "file allocation table"
it is a table that basically reads like an address book of sectors on a hard disk, so that data can be written to and read from using its address space. Was quite waseful of space as hard drives got larger so NTFS was introduced to compensate for increased disk size and journaling (recovery)
What are the steps of cold booting?
"Cold boot" means that the computer must be turned off then when it is turned back on it will "cold boot". A computer can reboot without turning off the power but some internal devices do not reset if the power does not go off. "Cold boot" forces everything to be restarted fresh.
What year was the USB introduced?
The Universal Serial Bus (USB) was made from multiple companies like, Intel, Compaq, Microsoft, Digital, IBM, and Northern Telecom. The USB was released in 1994. http://en.wikipedia.org/wiki/Universal_Serial_Bus#History
- Heuristics are "rules of thumb". A heuristic is an attempt at guessing an answer to a problem, which could be correct, but does not guarantee it to be correct (or even suitable). A common method of applying heuristics is to state the problem, record a number of possible solutions, and then eliminate those which are least likely to be correct. Continue comparing and eliminating until only one answer is left. That one is probably the closest to being correct.
- When dealing with computer viruses, heuristics are used to detect variations of the same infection. For example: One signature can detect "pbot.a", "pbot.c" and "pbot.d", even before the threat is "in the wild.
Heuristcis may be deoned alsio as "trial-and-error" procedure for solving problems (or reaching an unclear goal) through incremental exploration, and by employing a known criteria to unknown factors. For example, trying to climb a fog shrouded hill by making every step an upward-step. In journalism, a well known heuristic is asking Who? What? When? Where? Why? in investigating a news story. A heuristic employs independent discovery, and relies heavily on common sense, creativity, and learning from experience. Unlike an algorithm, however, it offers no guaranty of solving any problem.
the word comes from the Greek 'heuriskein,' that means to discover.
Hair drug testing is one of the important techniques to find presence of drug. Another drug testing includes blood, saliva, urine test etc

A video URL is a link to a video. Video URLs can be found on video sharing websites, embedded on web pages and shared via social media. To find a video URL, you can use your browser to search for the video on a video sharing website. When you find the video you like, you can use the browser to find the video URL.
Define constant linear velocity and explain how it applies to CD standards?
Constant angular velocity of a rotating disk means that, given a stationary base reference line and a zero line on the disk, both extending from the center of rotation to the outside edge of the disk, the periodic change in angle between the two lines remains a constant. Such a disk will have constant angular velocity (CAV) if its rate of rotation or revolutions per minute (RPM) remains constant.
While it would be technically possible to have the linear velocity of the disk remain constant by gradually decreasing the speed of rotation as the player head moves across the disk (because the outer paths are longer than the inner ones), this would make things more complicated both for the recording and playback machines, and therefore more expensive.
The paths of information on a CD (or DVD) are analogous to the grooves on an LP recording. The recording and playback heads move across the disk (CD or LP) as it rotates. Actually, of course, there is only one spiral path or groove; on an LP, it goes from the outside edge toward the center; on a CD/DVD, it goes in the opposite direction. In deciding on the parameters for the LP and CD, engineers had to involve the amount of data to be recorded and the spacing required to record that data versus the size of the disk, the speed of rotation, the data capacity of the disk material, and the sensitivity of both the recording and playback heads. ---- The above answer defines Constant Angular Velocity (CAV), not Constant Linear Velocity. The following is the definition to Constant Linear Velocity (CLV): "Constant Linear Velocity (CLV) is a CD-ROM (Compact Disc - Read Only Memory) format in which the spacing of data is consistent on the CD, but the speed of the disc varies on whether the data being read is near the cent or the edge of the disc." During CLV, in order to create the effect of constant speed as the CD turns, the CD drive uses a mechanism that slows down the disc when the laser beam is near the center of the disc, and speeds up the disc when the laser beam is near the outer edge. Thus, the beam is over a sector for the same amount of time, no matter where the sector is.

How many HD movie in 1 terabytes?
If you download the movies by torrent, and they are about 6-7 GB per movie (1080p), then you do the math 1000/6.5, that makes about 154 blu-ray movies. But the disk size isn't the problem, the problem is the way of downloading that much espicially if your ISP has limited bandwidth.
