What is the difference between encoding and encrypting?
opening/playing/reading/watching a file (Decoding) and making a file (Encoding)
there are many different ways to read/write a bunch of "1's" and "0's." A files extention (.wav; .mp3; .iso; etc) explains how that file should be read as/written as. For example, this paragraph could be written in Spanish and generally say the same thing with the same general letters.
What is the definition of a digital computer?
it deals with logic 1 and logic o where logic 1 is represented by a voltage and the other is also represented by a voltage
There are both digital and analog electronic devices. Digital devices use a binary input - that is, the electrical signals they use to perform functions are in one of two states - a predetermined high or low voltage threshold (sometimes referred to as "on" or "off, 1 or 0 or True or False).
Compare that to analog devices which receive electrical input that use either a constant, direct current, such as that supplied by a battery without any conversion process, or from an alternating current, such as that supplied by your home outlet. The alternating current rises and falls gradually through a series of different states (voltages), rather than the abrupt on/off states that digital equipment requires.
In reality, many electronic devices use a combination of both analog and digital input to accomplish a variety of tasks. For instance, your computer's fan may use an analog signal, while it's processor relies on digital signals to produce output.
How does a price scanner work?
A price scanner is often found in supermarkets and they allow customers to check the price of any given product. A price scanner works by reading the bar code.
If you were to go to a bank website or something and a certain place is like for the workers or something and you wanted to get in but you hvae to have a special access code or something and you arnen't a worker then that would be unauthorized accuesss.
What is the difference between a pay-as-you-go phone and a TracFone?
The difference is mostly the cost per minute of use. A Go-phone is usually 1.00 for each day of use and .10 a minute; 2.00 would get you 10 minutes of use. A Tracphone is usually .25 a minute; 2.00 would get you 8 minutes.
What is the major difference between first generation and second generation languages?
The difference between the two are that one has hispanic babies and the other is a fat cow.
What is the diff between CD and DVD?
CDs were made earlier than DVDs. CDs were a new version of the very old black disks. DVDs were invented later, DVDs are put in a rectangler box because it was an earlier version of a video tape.
What is the differences between photos images pictures and graphics?
An image is a slightly broader term.
A computer graphic refers to a graphic that was typically generated by a computer and stored on one.
An image can also refer to graphics that are not created by computers, but for example by other digital devices (cameras) and stored on them.
What is the difference between a notebook computer and a sub-notebook computer?
A subnotebook (sometimes also called mini notebooks or ultraportable) is a class of laptop computers that are smaller and lighter than typical notebooks.
Unlike UMPCs, they generally are found to run full desktop operating systems such as Windows or Linux, rather than specialized software such as Windows CE, Palm OS or Internet Tablet OS.
What is the difference between machine instruction format and micro instruction format?
Micro instrution
A single instruction in microcode. It is the most elementary instruction in the computer, such as moving the contents of a register to the arithmetic logic unit (ALU). It takes several microinstructions to carry out one complex machine instruction (CISC). Also called a "micro-op" or "µop," microinstructions differ within the same computer family and even the same vendor. For example, although all are x86 chips, the microcode for Intel's Pentium 4, Pentium M and AMD's Athlon are not the same. The software programmer never sees microinstructions, and they are not documented for the public.
Machine code - simple instructions that are executed directly by the CPU.
In other words, it takes many micro instructions to make a machine code. Micro Instructions work with the ALU wheras Machine Code works directly with the CPU
Difference between layer2 and layer3 switch?
A network device that forwards traffic based on layer 3 information at very high speeds. Traditionally, routers, which inspect layer 3, were considerably slower than layer 2 switches. In order to increase routing speeds, many "cut-through" techniques were used, which perform an "inspect the first packet at layer 3 and send the rest at layer 2" type of processing. Ipsilon's IP Switch and Cabletron's SecureFast switches were pioneers in cut-through switching.
What is the difference between physical memory and logical memory?
Look at it this way,
Say a application needs something computed by the CPU. That application says to the CPU, "I'm going to send you 500 pieces of data, so I need a space in the memory that is 500 pieces of data big." So the CPU takes a look at the memory. Initially there is room for 10,000 pieces of data, but because there are other processes already running the first 1 - 2,000 pieces are already taken up. The CPU says to himself from piece 2,000 to 2,500 is were all new data is going to go.
The physical memory is the address from 2,000 to 2,500.
Now the application doesn't realize that there are other processes that the CPU is taking care of. All it sees is the data 1- 500 pieces stored in the memory. This is logical memory.
When the application wants to run a piece of data of the 1-500, its says to the CPU run the piece 130. In reality 130 is not even a space in the memory that the CPU has set out for the application. Because remember it was originally 2,000-2500 that was set aside for the application. Piece 130 according to the applications logical memory is in reality piece 2130 in the physical memory. So when the CPU is receiving instructions from the application it has to translate the logical memory in to the physical memory and then back into the logical when replying to the application.
What do you do after you bit torrent a file?
To download torrent files (.torrent) from any website you first need a program that will let you download those files in that format. A very reliable torrent downloading software is Utorrent, which can be downloaded for free from:

I've posted some of the most popular torrent listing websites within the 'related links' for this question
Difference between a user interface and human-computer interaction?
Human-computer interaction (HCI) is the study of interaction between people (users) and computers. It is often regarded as the intersection of computer science, behavioral sciences, design and several other fields of study.
Interaction between users and computers occurs at the user interface (or simply interface), which includes both software and hardware; for example, characters or objects displayed by software on a personal computer's monitor, input received from users via hardware peripherals such as keyboards and mice, and other user interactions with large-scale computerized systems such as aircraft and power plants
What is the difference between domestic and industrial water use?
Most domestic water is used for waste disposal and washing, with only a small amount used for drinking. Most industrial water uses of water are for cooling and dissipating and transporting waste materials. From Mcgraw Hill "Environmental Science A Study of Interrelationships" Pg. 362

What is remote method invocation in distributed systems?
RMI stands for Remote Method Invocation. It is a mechansim that allows objects located in different computers in a network to interact. It is usually used in Java. It is quite similar to RPC(Remote Procedural Call).
A style sheet is a document written with a list of rules and declarations that control the presentation of web documents. The standards used are from the W3C standards for Cascading Style Sheets or CSS. These rules allow a designer to build a style sheet document that controls how and in what way a marked up document is to be presented.
What is the difference between ECR2032 and CR2032 batteries?
CR series batteries are part numbered by size. a CR2032 is 20mm X 3.2mm where as a CR2030 is 20mm X 3.0mm. If there is enough "give" in the battery holder you can use a 2032 where a 2030 fits. Usually not vise versa
