The principal disadvantge of too much multiprogramming is the overhead of excesssive context-switching. If the context-switch rate is too high, the overhead can actually overwhelm the benefit of multiprogramming.

high security areas use a) fingerprint scanners

B)feet recognition systems

C) iris recognition systems

d)signature verification system

its one of these answers and im not understanding which

Somethimes it uses a program in the operating system, but it really just depends on the OS

This is usually called emulation.

Common causes could be a power surge or overheating.

Building a laptop from the ground up might be too challenging for most people. A better idea is to find a laptop that is no longer working (no power supply, ruined motherboard or shattered display) and replace a only few parts.

From a scrap metal perspective, electronic recycling is the reclamation of valuable scrap from electronic devices. For scrap electronic devices prices, tryhttp:/www.scrapmetalpricesandauctions.com Electronics devices and/or components have very dangerous materials embedded within that must be scrapped for safety. The benefits of recycling is that gold and other precious earths are includedin the recovery.

When a kernel thread suffers a page fault, another kernel thread can be switched in to use the interleaving time in a useful manner. A single-threaded process, on the other hand, will not be capable of

performing useful work when a page fault takes place. Therefore, in scenarios where a program might suffer from frequent page faults or has to wait for other system events, a multi-threaded solution would

perform better even on a single-processor system.

they have gotten faster and more powerful. smaller. cheaper and things like that

Hi,

Natural Join: It is combination or combined result of all the columns in the two tables.

It will return all rows of the first table with respect to the second table.

Inner Join: This join will work unless if any of the column name shall besxame in two tables

An inventory system helps to make sure that product purchased from a supplier is correctly dispensed to the customer: This cuts back on overhead, waste (where products are perishable) and can help you to minimize theft (internal and external)

they will be fast and smarter than some humans...

Currently (in 2012) the most powerful cluster computer is the K Computer, located in Japan. This computer uses Fujitsu infrastructure comprising many CPU cores and fast network transmission. It can perform around ten petaflops per second. Each petaflop is equivalent to one million billion (10^15) math operations.

The earliest computers could only send 8 bits at a time, it was only natural to start writing code in sets of 8 bits. This came to be called a byte.


It's essentially arbitrary, however 8 bits was initially a good fit since it was able to easily fit all letters, upper and lower case, plus all punctuation and numerals. A Byte is no longer a hard boundary, however. There are many protocols that use individual bits, or groups of 4 bits, or any number really. Modern processors also use 32-bit "words" and 64-bit "words".

I have asked a few people and all of them mentioned same thing. Buy things on internet, pay our counting and book flights on the web. Many of them said that you can't live without a computer at home today; it may help you very much. In the future it will be more ordinary to buy things and use the computer. The computers will be faster, better and more confident to use the computer.

In short, computers are VERY useful to make everyday life a LOT easier. Everything from your cell phone, http://www.answers.com/topic/dvd-player, TV, has some sort of microprocessor in it giving it some form of computer like ability. The computer you used to type up this question made life easier for you, instead of having to mail FAQFARM a letter, you got to submit the question up front right here on the FAQFARM question forums.

* The main difference is that pipeline processing is a category of techniques that provide simultaneous, or parallel, processing within the computer and serial processing is sequential processing by two or more processing units.

An intranet is similar to the Internet itself in many ways, but for the fact it is a severely reduced version, accessible and editable only by certain listed parties. Information can be posted, edited and retrieved from it in much the same way as the Internet as a whole; however, it can be considered much more reliable as (for example) employees within a company can be confident that the company intranet system holds valid information, whereas information on the web is not always entirely reliable and should be treated with appropriate skepticism and caution when being cited.

A WAN (I'll assume you know what it stands for), is exactly what it says on the tin. It is a network between terminals spread out over a large distance. It is a more secure data transfer method than the public Internet: of course assuming said network has safeguards and security protocols, for which there would be no reason to assume it wouldn't.

In conclusion and to round to your answer: An intranet is a system akin to a miniature "world-wide-web" only accessible to predefined users. Whereas, a Wide Area Network is in its simplest form a much further expanded version of the basic LAN networks employed by many businesses, governing bodies, educational institutions and other independent entities with use of a computer system.

Examples:

Canon Global Inc. as an international company do make use of an internal network: The Canon Intranet.

Whereas...

Major Oil Companies may well find it easier to run a WAN, as they have many derivative branches that perform independent tasks long distances away from one another that must share information (i.e. extraction, distillation, offices, etc).

Microsoft is a software company, Microsoft is not a computer. They make operating systems, and software, not computers.

Microsoft is owned by shareholders. Bill Gates did own the largest part,and was CEO,

but has left the company.

There are various types of computer systems for different purposes. Supercomputers of High-end Servers are used by big corporations to keep their systems running. Personal computers or laptops are aimed for commercial use by individuals.
