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.

Is a computer Repairman the same as a computer scientist?
No, a computer repairman is a computer technician. A computer scientist is someone who studies the architecture of computers and helps design them. They are at opposite ends of the spectrum. A computer scientist is much like an architect in that they design things for manufacturers to build, creating ideas for new technologies and new types of systems, while a repair technician rebuilds computers back to an operating state based on how they are already designed.
Is lesson time wasted during power cuts when technology cannot be used?
No. The teacher still has a voice, and the student still has an ear. Both, also, have a brain.
How do you delete your computers history?
It depends what browser you are using. I use Google Chrome. To erase search history on Google Chrome:
Look for the little spanner in the top right hand corner, hover your mouse over it and it should say Customise and control Google Chrome.
Now, click it. A list of options will appear.
Click History.
Then on the right hand side of the list, click Edit Items... then Clear All Browsing data.
A check list will appear in a new tab, make sure you have the settings set to obliterate the following items from: The beginning of time.
Then check all the boxes that apply and click clear browsing data.
Then close that tab and return to the History tab, and click Finished Removing items to the right of the now empty list.
You have now cleared your search history.
What are the differences between synchronous and asynchronous time division multiplexing?
1)
IN syncronous TDM , the multiplexer allocates exactly the same slot to each device at all times , whether or not a device has something to transmit
in contrast, in asyn TDM if thedevice have nothing to transmit then its time slot is alloted to another device.
2) synch TDM requires a common clock signal at both the ends ( sender & receiver)
asynch TDM dsnt require a comn clock ..
3) if synch has n input lines , the frame contains a fixed no. of at least n TM slots.
if it has n input lines , the frame contains not more than m slots where m< n
Computers run off of power. You will need to plug your computer into an outlet and turn it on.
What are uses of computer in science and engineering?
the use of computer to science and eng'g is by helping it to create some of the important factors or simply using a computer to create an image about their plan by means of using programming languages.
Is a card reader input or output device?
yes it probably be a output device .....you may check further too
What is the difference between Markov Models and Hidden Markov models?
Unlike MM in HMM state is hidden.
LARGE COMPUTERS - are the ultimate in system sophistication, flexibility and speed. It has 512k to 8192k capacity and these have internal operating speeds measured in terms of NANOSECONDS. It is well suited for design and engineering work because its speed enables it to do mathematical calculations.
Artificial intelligence John Macarthy first defined in which era?
Artificial Intelligence was coined by John McCarthy in 1955.
1955 comes under the Industrial Era.
What is commond line interface?
The command line interface is one where the interaction with OS is possible by the commands and instructions. No Graphical facility is available like drag and drop facility.
What type of routing protocol advertises only new paths to other routers on the network?
link-state routing protocol
Which converts high level language into machine understandable codes!
Is assembler is required in complier to executable the code?
That depends on the programming language you're using. An assembler is used to translate assembly instructions into machine code. A compiler will only require this if it first translates source code into assembly.
What is unique about the Ada language design process?
it was the only programming language that was designed by a woman
A Jagged array is an array of arrays.
You can initialize a jagged array as −
int[][] scores = new int[2][]{new int[]{92,93,94},new int[]{85,66,87,88}};Where, scores is an array of two arrays of integers - scores[0] is an array of 3 integers and scores[1] is an array of 4 integers.
Why is Boolean algebra used in computer systems?
The circuitry that makes up the inner workings of a computer comes from transistor type circuits. These transistor circuits are configured to have only two states. For example, their output voltage might be either 5 volts or 0 volts. Because there are only two output states possible, it's very convenient to use Boolean logic to design these circuits since you can represent each state by a one(1) or zero(0), a 'Yes' or 'No', or a 'True' or 'False,' thereby able to easily exploit the Boolean operators.
There has to be a key on your keyboard, between 'X' and 'V', marked with 'C'. Press it!
The study of computers, how they are made, programmed and used.
Computer Science is a combination of theoretical and practical knowledge. The practical part of computing is available to see everywhere as almost every person on users' computer for certain tasks, whether it be designing, development or simply general tasks. Computer science is seen as a higher way to solve and analyze complex problems of any field, whether medical, business, engineering and so on.
What is a finite state machine?
Finite State Machine is a model to describe how the internal state of the machine varies due to the corresponding actions. The number of states of the machine are limited as the name suggests.
