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.

When a subroutine is called where is the address of the instruction following the call stored?

That varies between different processors:

  • Many put it on the stack automatically.
  • The PowerPC stores it in a register called the Link register and leaves it up to the software to determine where to save it.
  • The i960 pushes its internal general register stack automatically then stores it in one of the newly allocated general registers (along with a new frame pointer, etc.).
  • Some early computers (e.g. DEC PDP-1) stored it in the memory address preceding the subroutine itself.
  • Many computers in the 1960s (e.g. IBM System 360) stored it in one of the general purpose register specified in the call instruction.
  • etc.

What is the scope of system analysis?

System Analysis.. The individual who analyzes and designs software systems and provides maintenance and support function for the users-systems design. A class can be described as a collection of objects of similar type. These objects often share the same attributes, operations, methods, relationships, and semantics. Additionally, once a class is defined any number of objects can be created and associated to that class. For example, beagles and boxers represent different breeds (i.e. instances) of "dogs" which also can be viewed as a distinct class. Furthermore, defining classes, as part of the object modeling process is not that different from the traditional system analysis process, which seeks to achieve a goal (i.e. object modeling seeks to understand a solution; whereas, system analysis which seeks to understand a problem).

Attributes are data fields that represent some property of the containing object that is shared by all instances of the object's class. Attributes normally have names (e.g., "Address") and Types (e.g., "String" or "Boolean"). An example of this would be the "Address" of a "User." In addition, attributes define the characteristics of the class that, collectively, capture all the information about the class.

Encapsulation represents packaging several items together into one unit. In addition the application of encapsulation involves keeping the external representation of an entities properties and methods independent of its actual implemented use. Encapsulation therefore, allows an entity to be leverage by other parts of an application without the fear of changes in the implementation use causing a snowball effect.

Process Modeling

Logical Process modeling is a technique for organizing and documenting the structure and flow of data through a system's processes and/or the logic, policies, and procedures to be implemented by a system's processes....

How many constructors are there for the string class?

How many computer languages where developed?

There are hundreds of programming languages that have been developed since the inception of computing. Estimates suggest there are over 700 active programming languages today, with many more that are either obsolete or rarely used. Some of the most well-known include Python, Java, C++, and JavaScript, while others are niche languages for specific applications. The landscape continues to evolve as new languages emerge to meet changing technological needs.

How do you write a suitable objective in a resume for a computer science fresher?

Sample format for MBA Fresher Fresher Resume A fresher resume format is widely used by fresh graduate students who do no have a work background. Despite the limited experience of fresh graduates in the field that they are applying for, employers have a way to hire competent workers. It is therefore essential to know what their criteria are.

The major section in a fresher resume is the educational background. Employers sort through their applicants' resumes by reviewing academic achievements. Everybody prefers intelligent students so listing all your achievements while in school is the best strategy. List all your core competencies. Arrange them by subject and elaborate each in bullets. Awards and achievements also make a good impression to the employers.

Since you do not have enough experience, they assess your flexibility instead. This can be seen in the extracurricular activities you participated in. If you hold key positions and responsibilities in your university organization, you should highlight this. They want to hire people who are able to accomplish things, even at school. The last part includes personal information and references. Ask your professors to be your personal references. This way, you become more credible to the employers.

How can nabteb result get admintion into university with jamb?

To gain admission into a university in Nigeria using NABTEB results, candidates must ensure they meet the specific entry requirements of the institution, which may vary by program. Typically, universities accept NABTEB results for various courses, but candidates also need to register for the Joint Admissions and Matriculation Board (JAMB) Unified Tertiary Matriculation Examination (UTME) and achieve the required cut-off mark. After successfully passing both the NABTEB exams and JAMB, candidates can apply for admission through the university’s portal, often requiring them to participate in post-UTME screenings. Meeting all these criteria increases the chances of securing a place in the desired program.
