Is it true or false that a computer will be more efficient if its processor has fewer cores?
It depends on how you mean by "efficient". In terms of power consumption…less cores is generally better to have fewer because you have in essence two or more CPUs running at the same time. However, great leaps have been made by Intel to make exceptionally efficient multi-core processors.
In terms of processing, often more cores is much more efficient, provided the software used is capable of utilising multiple cores. This software is "multithreaded" meaning that it can accurately spread the processing across more than one core (or processor). Most more recent software makes full use of this.
Where is the Full list of Interrupt Vector Table?
The interrupt vector table in the 8086/8088 is the first 1024 bytes in memory. There are 256 vectors, each containing 4 bytes, CS:IP, for each possible interrupt source.
How much money can you get out of components from a Gateway CX210X model laptop?
The value of components from a Galaxy CX210X model laptop would be based on the need for those parts. Usually parts can lose their value based on age and if they have been used.
In what stores can one purchase ergonomic computer desks?
One can purchase ergonomic computer desks from several different places. Some of the places in which one can purchase ergonomic computer desks are: Heckler Design, and OSHA.
What the definition of itl 202?
There is no specific 'definition' as such, but there is however a message that is portrayed. You should go and get a life instead of findihg this sad crap out,

Have you tried to turn it off and on then delete your project. After that Your stuffed ahahah
When should one consider a mini desktop over a regular desktop?
"One should consider purchasing a mini desktop computer over a regular desktop when space is at premium, and there is not much to spare. The central processing unit of mini desktop computers is markedly smaller than that of a standard desktop which generally comes with a 'tower' or large horizontal desktop unit. The mini CPU's, generally have a foot print about the size of a magazine."
Can one buy antivirus softwares in computer shops?
"Of course. Computer and electronic shops offer a huge variety of antiviruses, like Norton, Kaspersky, or Antimobile. They will also come in hardware, software, or online application codes."
Where can one learn about Qigong?
Once can learn about Qigong in a variety of different ways. Once can approach associations such as the Qigong Institute or the National Qigong Association, read Qigong books, or learn from an instructor.
Make The Most of Small Office Spaces?
If you would like to maximize the space in your small office, you should look for a compact computer desk. You would be surprised by just how many compact computer desks are available, and many of them are creatively designed to still provide you with plenty of storage space.
OLT (Optical Line Terminal) is a device in a passive optical network that serves as the service provider's endpoint, connecting to and controlling multiple Optical Network Units (ONUs) at subscriber locations. ONU is a customer premises equipment that connects to the OLT in a PON system.
An Outside Plant (OSP) system refers to the network infrastructure installed outside of buildings, including cables, ducts, poles, and cabinets, that transmits telecommunications signals. OSP designs facilitate the deployment of cables and equipment for communication networks.
"Basic interview opt" may refer to questions related to optical network technology, such as understanding different types of optical fibers, WDM technology, network architectures, or troubleshooting common optical network issues during an interview for a position in the telecommunications or networking industry.
Why can't people draw on the computer?
Many people are great artist but they cant draw on the computer with a mouse.
Try writing your name on the computer and your name on a peice of paper, BIG DIFFERENCE
You might say " What about touch screen computers". That's the only way, but what are you going to draw on on a touchscreen computer?
Added - another option which works well for some people is a 'graphics tablet (or pad)'. This plugs in like any other peripheral, the pad can be as small as a mouse pad or up to about A3 size. A special pen (usually optical) is used for 'drawing' on the pad. As the pen feels like a normal pen or pencil to use good results can be obtained with some practice. Software can change the 'brush strokes' to look like pencil, ink, brush etc. Much used by architects and other designers. Moderately expensive.
What type of menory is used to temp store info that the computer is currently working with?
There are several. The hard drive is a kind of memory. It is non-volatile, meaning when you turn off the computer the information stays.
From there it goes into system RAM, the sticks that stick up out of your motherboard. RAM stands for Random Access Memory, and that's what these are. They are designed to accept information quickly, provide access to the information quickly, and erase it quickly. With current technology they are also volatile, meaning they lose the data when the power goes off. This is the workspace for the computer.
From there it is read by the CPU. This chip is really a massively powerful calculator. In fact, its so fast that it has its own memory chips built in. And not just one, it can have up to three separate groups of RAM. These are called the CPU's cache (pronounced "cash".) They are optimized for the CPU to retrieve data extremely quickly and write it extremely quickly. The cache's purpose is to have everything the CPU needs at a moment's notice. If you remember the Intel CPU called the Celeron these were cheap because they had very little cache. At first they had toolittle and it really restricted the CPU's performance.
After the CPU does its computations the result goes back through its cache and probably goes back to system RAM to be temporarily stored for more computations (like when starting up a program) or for some other program to refer to it.
No, you're not done yet. Microsoft knows how important system RAM is (people were very unhappy with how much RAM Windows Vista needed, and Microsoft specifically addressed this complaint in Windows 7) and Windows tries to keep as much free as possible. Less important information in RAM is "swapped out" to a temporary holding spot on the hard drive. Terms associated with this are virtual memory, swap file, and pagefile. Data is also swapped out if you don't have enough RAM - in this case the virtual memory acts like an overflow. Has anyone ever told you "more RAM makes your computer faster"? It doesn't, technically - it helps reduce swapping from RAM to the (much, much slower) hard drive so your computer can run at its best speed.
Still not done! Computer manufacturers have realized how very greatly cache helps, acting as a temporary space or a fast retrieval space as it does. Hard drives all come with their own cache now. This cache acts like a buffer so that Windows can throw a big chunk of data at the hard drive and not wait for it to actually be written. The hard drive reports "I got it!" when actually the data is in the hard drive's cache. Have you heard the term "flush the cache"? That refers to getting all the data in the buffer written safely to the hard drive.
Cache, buffer, flash, RAM... if you are thinking "aren't all these memory that store data?" you're right. The system RAM, the CPU's caches, and the hard drive's cache are all volatile. The virtual memory (the swap file) is not really volatile, because it is an actual file on the hard drive, but its more like a one-time-use place. The data in the pagefile is not intended to be reused, just used and changed, like system RAM. The hard drive and your flash drive / portable memory stick are nonvolatile. The hard drive stores data by magnets, and the flash drive stores it by NON-volatile RAM. Why not make the hard drive and system RAM from the same stuff as your flash drive? Currently, non-volatile flash is far more expensive than a hard drive, byte for byte; its much slower than system RAM; and it actually wears out after thousands of write-erase cycles.
By the way (did you think I was done?) now there is even a level of cache meant for the operating system's use! Two similar and somewhat competing systems just came out, Windows' Readyboost and Intel's Turbo Memory.
People show their emotions in many diverse and specialized ways, some of which a computer can be programmed to detect. By that, a computer will then give you a supportive response..
Can you get delay when using higher quality monitors?
Depends on the monitor in question. Find the devices data sheet and look for the Display Latency (or something similar) anything under ~1 milliseconds is not noticeable. This latency is the amount of time it takes from the monitor's controller to push the data to the display after it has been received. If you are just watching a movie this really doesn't matter, but if you are playing a video game or something that requires the monitor to update as soon as the this latency can play a big factor in the usability.
What is horizontal centering in formatting?
It's the process of aligning each line of text to a central tab stop on the page. The program 'counts' the number of characters on each line of text - then positions it so the space at each end of the line is equal
What does 'do graphics included in the help facility help with understanding' mean?
