A set of computer instructions that carries out a task on your computer is?
Normally, those are referred to as the "application" programs.
A computer may be running any number of programs, all at the same time. The operating system manages the system's resources, the network programs allow the computer to communicate with other computers, and the graphics programs help to display information visually on the computer monitor.
None of those, by themselves, are useful to users.
In order to perform a task, such as fill out a tax return, you need a program written to perform that application (hence, they are called "applications" or "application programs). These programs actually do something useful for a person, and they utilize (and communicate with) the others programs that are running on the computer in order to complete the desired task.
ECC can detect the error but cannot correct it.
What is the difference between database administrator and database analyst?
An administrator can manage, create, delete and update a database.
The manager can just update and manage (complete fields). He can't create or delete database.
I am a database administrator. An Administrator takes care of the database--having privileges to do anything to a database. Create objects, delete objects, drop objects. A Database Manager is a supervisor over the Database Administrator. Usually a database manager does not know the specifics of an administrator position--but must have high level knowledge of how a database works.
That is not to be confused with the database manager that is the non-human engine for the database that provides authorization control, makes integrity checks, and commands the processor.
Distinguish between internal and extarnal commands with examples for unix?
Internal commands are executed by the shell and do not exist as a separate binary program. You can find out which of these there are by looking at the 'man' entry for the shell you are using.
External commands can be found in various directories, such as /bin, /usr/bin, etc.
How radio communication devices work?
Sound and radio waves are different phenomena. Sound consists of pressure variations in matter, such as air or water. Sound will not travel through a vacuum. Radio waves, like visible light, infrared, ultraviolet, X-rays and gamma rays, are electromagnetic waves that do travel through a vacuum. When you turn on a radio you hear sounds because the transmitter at the radio station has converted the sound waves into electromagnetic waves, which are then encoded onto an electromagnetic wave in the radio frequency range (generally in the range of 500-1600 kHz for AM stations, or 86-107 MHz for FM stations). Radio electromagnetic waves are used because they can travel very large distances through the atmosphere without being greatly attenuated due to scattering or absorption. Your radio receives the radio waves, decodes this information, and uses a speaker to change it back into a sound wave. An animated illustration of this process is given below (mouse-over the images for animations).
A sound wave is produced with a frequency of 5 Hz - 20 kHz.
The sound wave is equivalent to a pressure wave traveling through the air.
A microphone converts the sound wave into an electrical signal.
The electrical wave traveling through the microphone wire is analogous to the original sound wave.
The electrical wave is used to encode or modulate a high-frequency "carrier" radio wave. The carrier wave itself does not include any of the sound information until it has been modulated.
The carrier wave can either be amplitude modulated (AM, top) by the electrical signal, or frequency modulated (FM, bottom).
-Forones
The signal is transmitted by a radio broadcast tower.
Your radio contains an antenna to detect the transmitted signal, a tuner to pick out the desired frequency, a demodulator to extract the original sound wave from the transmitted signal, and an amplifier which sends the signal to the speakers. The speakers convert the electrical signal into physical vibrations (sound).
connectionless protocols - transport layer
A URL (Uniform Resource Locator) is a website address e.g. www dot wiki dot answers dot com.
They are used for translating website IP addresses into easy-to-remember text.
Without URLs, you would have to type in the servers domain name every time you wanted to visit a website. A domain name is like a websites phone number or address. WikiAnswers, for example, is found at 67.196.156.63. Without a URL, you would have to memorise these numbers every time you wanted to visit the website.

Why is writing onto a CD or DVD called burning?
Writing a CD or DVD involves using a powerful laser to melt a dye inside the disc to a special pattern. Since melting can often be seen as a form of burning, and since burning sounds cooler, it is the preferred name.
there are 4096Mb in 4.00Gb if you are talking 1024Mb per Gb but if you are not it's only 4000Mb to 4Gb
How many bytes are there in 1gb of ram memory?
Exactly 1 073 741 824 bytes
AnswerThere is 1024MB in 1GB, 1024KB in 1MB, and 1024Bytes in 1KB.1024*1024*1024*=1,073,741,824 bytes is in 1GB.
Difrence between data and information?
Data are individual elements and information is what you can derive from it. A list of numbers is data. Their average or total is information. A list of the birthdays of all of your friends is data. The amount of them that were born in the month of April is information that you can get from that list. The name of the person who is the oldest of them is information.
What is a legitimate URL as shown by its extension?
File extensions are the letters that appear after the period in a URL. Typical "legitimate" file extensions for web pages include:
- www.xxx.htm
- www.xxx.html
- www.xxx.com - business site
- www.xxx.net - business site
- www.xxx.edu - education sites
- www.xxx.org - official organization, such as a non-profit org
- www.xxx.pdf
- www.xxx.php
- other specialized types of files
It's used to connect widely-separated groups of users. Example: You're the IT lead for a company that makes stuff for the army. You've got branch offices outside Fort Bragg, Fort Hood, Fort Riley and Fort Lewis--and they all need connectivity to an IBM Z/Server in Seattle. The Internet won't work (although it is a WAN) because you're passing 5GB files and can't afford any dropouts, so you put two satellite dishes on the roof of each branch, point each at a different geostationary bird, and set up redundant lines of communication. Although i can't explain more on this topic here, please read this article to more about How a wan can be used - http://www.wanredundancy.org/resources/wan-routing/introduction-to-wide-area-networks/wide-area-network-wan.html
The control unit is one component of the?
its located in the central processing unit which is your microprocessor in simple words.
its job is to check device status and control computer components
What are considered input devices?
input devices are those devices through which we give input to our device or system,...i/e keyboard, mouse, video cam, scanner or e.t.c
Why should you never bury a cache?
Burying a cache can lead to several problems, including difficulty in locating it later and potential damage from environmental factors like moisture or soil erosion. It may also violate local regulations or guidelines regarding caching, leading to penalties. Additionally, buried caches can be discovered by wildlife or other people, resulting in unintended consequences. Overall, keeping caches above ground ensures easier access and reduces environmental impact.
Bit rate would be the number of bit processed per time frame, normally per second
Old modems commonly worked as 4800 Baud or 9600 Baud which would be 4800 bits per second and 9600 bits per second respectively
Using the term placeholder in a mathematical sense means that a significant zero is in place of a number. This is usually as a decimal representation.
