Computer Science
Computer Science is the systematic study of algorithmic processes that describe and transform information. It includes the theoretical foundations of information and computation and the practical techniques of applying those foundations to computer systems. Among the many subfields of Computer Science are computer graphics, computer programming, computational complexity theory, and human-computer interaction. Questions about Computer Science, terms such as algorithms and proofs, and methodologies are encouraged in this category.

Search Advantages of Social Networking, Or Advantages of Social Networking on portable devices.
What is the difference between geographic information system with other information system?
There is very less difference between GIS and land information system.
One is that Land info. system is subset of GIS .
Actually GIS takes care of the entire geography of the earth ,it takes into
account the every part of the earth be it land ,mountain,ocean ,desert,lake and many more geographical structure whereas the land info. sys. just gives the information about
the land areas of the earth and the land use information also.
But both take help of multiple data sources like remotely sensed data ,GPS,
different datum projection system..........

Not in the sense that humans do. However computers can be programmed to develop their abilities and broaden their range of tasks. On the internet there are examples, like intelligent routers. Over a period of time they will build a database of other computers and routers that communicate with them. They can then become more efficient at sending data across the internet, by sending it to a router that it will know can pass it on a shorter or quicker route. This is just one of many examples of how computers can learn. But they have to be designed to do so, so the ultimate control still remains with those that design the hardware and software.
Why it is important to produce an overall description of system architecture at early stage?
The overall description is very important as it describes what the customer wants their system to do when it is finished. Many well meaning people have found how expensive in time, effort and money it is to change a well described well, designed, well built system to something else
Which precaution should be taken before any electronic component is removed from a computer system?
make sure that the computer is unplugged
well since a geobyte is really just a 1 with 29! zeros after it there is really no need to have more and plus the ram sytem would have to be the size of a car to fit that much so even trying to get 1 after would have to be much greater in size
There is
Saganbyte (SB) -> as Geobyte 1024
Jotabyte (JB) -> as Saganbyte 1024
Gatobyte (GAB) -> as Jotabyte 1024
What is a macro in computer science?
A macro is a small 'program' or 'computer' instruction, usually created via a scripting language, the instruction represents a larger sequence of instructions. For example say every morning when you get to work you * open email * open a workspace * open the calculator * open a calendar * log into a webpage well you could record or write all of these as a macro and instead of clicking this that and the other you could click one thing - the macro you recorded or wrote and go get a cup of coffee and when you got back your system would be ready for you to go to work!
How can computers be distinguished from other machines or devices?
The Main difference between a computer and a machine that computer is an intelligent device which has the ability to decide by its own through processing different data analysis while machine is least intelligent and is always waiting for user

Difference between hardware and software failure?
Should be obvious. Hardware faults are problems with the hardware. Software faults are problems with the software. Hardware = physical components of the computer (i.g. motherboard, hard drive, power supply). Software = computer programs
Can tester test software without software specifications?
According software testing procedure the tester should be provided with software specification without understanding the procedure the tester is going to test nothing
ODBS in computer stands for Open database connectivity. Whenever we are working on a project let it be java or php the to store the data in our project we need a database. For this this we need to create a database connection that is ODBC.
They are many ways you could use a computer unethically. Some of the most common ones will be by creating viruses, sending spam mail, spywere, etc.
Another way one could used a computer in an unethical way, is by using a computer with restrictions to do tasks outside your privileges, for example, in a business watching pornography material, in a school by accessing restricted sites. Also it is consider to use a computer unethically, when one illegally download copyrighted material being, music, videos, games, etc.
What are the characteristics of system analysis?
Characteristics of system analysis:
1. The system analyst must be able to communicate in writing and orally.
2. The analyst must easily get along with people.
3. The analyst must be a good listener and be able to react to what people say.
"Busy waiting" is the act of actively waiting for some condition to change.
In programming microcontrollers, one might want to wait for a pin to become high or low before continuing with the program.
A "busy waiting loop" in C would look like this:
...
while(PIN1 != HIGH)
;
...
This essentially does nothing but check the value of "PIN1" time after time, waiting for it to become "HIGH".
Now, if PIN1 were to become "HIGH", the processor "breaks out" of this busy-waiting loop and continues with the program.
How long does it take to obtain a BS in computer science?
A bachelor's degree in most areas can require between 124 to 128 college credits particular to a specific program of study. This would be based on a college or university that operates on a regular two semester academic year which is the most common. For institutions that operate on a tri-semester or quarter-semester it would be quite different. That being said, the Bachelor's degree - in most cases - is designed as a four year program of study, provided the student is full-time and follows their chosen program of study as prescribed by the college or university, and also provided the individual does not require prerequisite or developmental coursework as a result of basic skills testing. The minimum credit load for a full-time student is no less than 12 credits per semester. However, to complete the degree within the four years, a credit load of approximately 15 to 18 credits is recommended. For individuals who work or who have other responsibilities that would prohibit them from attending full-time, completion of the degree may take twice as long. Still, some of this time can be cut down by attending summer sessions and/or interim sessions. In addition, the bachelors and associate degrees are referred to as undergraduate degrees while the Masters and Doctorate degrees referred to as graduate degrees.
What is an 16 bit microprocessor?
In computer architecture, 32-bit integers, memory addresses, or other data units are those that are at most 32 bits (4 octets) wide. Also, 32-bit CPU and ALU architecturesare those that are based on registers, address buses, or data buses of that size. 32-bitis also a term given to a generation of computers in which 32-bit processors were the norm.
The range of integer values that can be stored in 32 bits is 0 through 4,294,967,295 or −2,147,483,648 through 2,147,483,647 using two's complement encoding. Hence, a processor with 32-bit memory addresses can directly access 4 GB of byte-addressablememory.
The external address and data buses are often wider than 32 bits but both of these are stored and manipulated internally in the processor as 32-bit quantities. For example, the Pentium Pro processor is a 32-bit machine, but the external address bus is 36 bits wide, and the external data bus is 64 bits wide.
32-bit - Computers or software programs capable of transferring data 32-bits at a time. Examples of 32-bit operating systems are OS/2 and Windows NT. The first true 32-bit processor was the Intel 80386. 32-bit can also refer to the amount of colours a video card is displaying. 32-bit is the same as 16.7 million colours (24 bit colour with a 8-bit alpha channel).
