Answer:
disk caching
Explanation:
Hi,
Magnetic hard drives use disk caching to speed up performance. This method is quite ingenious because what it does is that in a section of memory in your pc, it keeps a copy of information that was previously accessed in the hard disk. So, next time if the same data is requested, the system can refer to cache to get quick access rather than going to the hard disk (which is slower).
Answer:
Step 1 : Start
Step2 : Input first number, num1
Step3 : Input second number, num2
Step4 : product - - > num1 * num2 (product of num1 and num2)
Step5 : Input product, myanswer
Step6 : comparison - - - > correct or incorrect based on myanswer and product
Step6: print(comparison)
Step7: End
Explanation:
Algorithm is a sequence of instructions a computer is expected to follow to solve a particular problem.
Required :
Two inputs ; num1 and num2
Expected output
Algorithm :
Step 1 : Start
Step2 : Input first number, num1
Step3 : Input second number, num2
Step4 : product - - > num1 * num2 (product of num1 and num2)
Step5 : Input product, myanswer
Step6 : comparison - - - > correct or incorrect based on myanswer and product
Step6: print(comparison)
Step7: End
The two numbers to multiply are entered ; the product is calculated by the program ; the the user inputs his or her own expecteted product ;
Both are compared and the output of the comparison is displayed (either correct oe incorrect)
Answer:
Addresses.
Explanation:
An argument can be defined as a value that can be passed to a function.
Simply stated, an argument is a value that must be passed into a function, subroutine or procedure when it is called. This value can be passed to a function either by reference or by value.
This ultimately implies that, an argument which is also a parameter variable stores information which is passed from the location of the method call directly to the method that is called by the program.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
When calling a function with arguments that should be modified, the addresses of those arguments are passed. This is simply because the argument is an address or pointer in itself and as such the function parameter being called must be a pointer.
In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.
Hence, all instance variables that have been used or declared in any superclass would be present in its subclass object.
Answer:
Explanation:
some distros like ubuntu do not even allow su to switch to root. furthermore the su to root is dangerous because the user becomes the all-powerful administrative account, so no warnings are issued if the application team user tries to do something system-breaking.
Answer:
C. receiving data.
Explanation:
An information system interacts with its environment by receiving data in its raw forms and information in a usable format.
Information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.
Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.
Additionally, an information system comprises of five (5) main components;
1. Hardware.
2. Software.
3. Database.
4. Human resources.
5. Telecommunications.
<em>Hence, the information system relies on the data it receives from its environment, processes this data into formats that are usable by the end users. </em>
