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.

Computer application in finance and accounting?

Yes, computer applications are used greatly in the field of finance and accounting.

What is the limitations of jk flip flop?

When j=1 an k=1 and the clock pulse signal which remain at logic 1, after the output have been complemented once will cause repeated and continue transmission of output. This situation is called "raised condition".

To avoid this undesirable operation, the clock pulse must have a time duration which is shorter then the propagation delay through the flip flop.

What is it called when your computer doesn't recognize a character and it shows up as a square?

it means that the character you were trying to wrrite was an extended ascii character which isn't supported in you computer

What is open and close architecture?

An open architecture in computers/technology is one in which the details are published and are known. Anyone can contribute to the technology because it has been well described.

A closed architecture is the opposite. Sometimes we call these proprietary architectures because little is know about them except by the creators, and they aren't telling ...

Why legacy software are still being used?

It's usually cheaper for companies to use and maintain old software than it is for them to have new software written and tested.

What is optical fiber explain?

optical fibers are strands of glass or plastic that use light to pass information. It is very fast and is not disturbed by electromagnetic fields.

Define file computer term?

A computer file is a block of arbitrary information, or resource for storing information, which is available to a computer program and is usually based on some kind of durable storage. A file is durable in the sense that it remains available for programs to use after the current program has finished. Computer files can be considered as the modern counterpart of paper documents which traditionally were kept in offices' and libraries' files, which are the source of the term

What is a directory computer science?

A directory is a location for storing files on your computer. Directories are found in a hierarchical file system such asDOS, OS/2, Unix, etc. When referring to a directory, a user commonly indicates the name of the directory.

How can I read from file list of data?

Here is a simple example:

// contacts.txt

John,Smith,555-1234

Jane,Doe,555-6442

// reader.php

<?php

// file function turns each line in the file into a row in an array

$file = file('/path/to/contacts.txt');

foreach($file as $line){

$contact = explode(', ', $line);

print_r($contact);

}

?>

Static versus dynamic network in SIMD interconnection network?

Static- Links between two processor are passive & dedicated buses cannot be reconfigured for direct connection to other processor.

Dynamic- It can be reconfigured by setting the n/w active switching element.with different classes i.e single stage & multistage.

What is the most commonly used form of AI in the business arena?

I'd have to guess machine learning. Very big with hedge funds, who use it to detect patterns in newsfeeds, blogs, tweets, and buy or sell accordingly.

What factors affect selection of granularity size for data item?

There are several factors guiding granularity selection: 1) overhead - the more granular the more objects and methods in supporting code, 2) regulatory - there may be compliance mandates specifying what granularity will be maintained in the data, 3) industry practice - your granularity should generally match that of cloud and third-party products if your system will be integrating with these services. For example, do not combine first and last name as a single data item if every one else manages these as two separate data items.

What are necessary properties of RISC CPUs?

  • a "reduced" instruction set, consisting only of the instructions most commonly generated by compilers
  • all arithmetic and logic instructions operate only register to register using an internal register set
  • only basic arithmetic and logic operations are built in, others handled in software
  • all memory access instructions are simple register load or store instructions
  • only one memory access mode built in, others handled in software
  • instructions always aligned whole words (no short or unaligned instructions)
  • significant degree of pipeline parallelism in the hardware to optimize hardware efficiency
  • etc.

What allows the computer to start?

When a computer is powered on, the CPU loads BIOS into memory, and then, based on the BIOS boot configuration, loads physical sector 1 from that boot device to a specific memory location, and then jumps to that memory location to begin executing the master boot loader code. Drive geometry is determined, and then the master boot record entries determine where each partition's logical boot sector is located on the device. It finds the active partition, reads that partition's boot sector code into memory, and then jumps to that location. Once it does that, it follows the instructions in that boot loader code to switch to Protected Mode, allocate necessary memory, load the operating system into memory, sets up descriptor tables, and then jumps to that location. At that point, the operating system is actually executing...and the rest of the system loads.

How would you change the mouse speed?

This will work for the last few Windows editions: Press the start button or the Windows key, then select "Control Panel". Now go to "Printers & Other Hardware" where you will find the "Mouse" icon. Click on this and the "Pointer Options" tab where there is a clearly marked slide bar to change pointer speed.

What is the speed of an OC-3 connection?

An OC-3 circuit's bandwidth capacity per full port is 155.52 Mbps. This of course is if you dedicated it to one source. If it is divided and multiplexed, you will have to note there will be less bandwidth per channel.
