Computer Programming 1 Prelim Exam

A computer is an electronic device capable of performing complex computations in a short time. It can process and store large amounts of data, perform calculations, and execute instructions to carry out various tasks. Computers can be used for a wide range of applications, such as word processing, internet browsing, gaming, and data analysis. They rely on software and an operating system to function effectively. Therefore, a computer is the correct answer as it encompasses all the capabilities mentioned in the question.

The given correct answer is "Application Software" because it refers to computer programs that are designed to perform specific tasks for computer users. This includes creating and editing documents, making graphic presentations, and listening to music. System software, on the other hand, is responsible for managing and controlling computer hardware, while an operating system is a type of system software that provides a platform for running application software. Office applications are a specific type of application software that are used for tasks related to office work, such as word processing, spreadsheet management, and email communication.

The given answer, "Software Development Life Cycle," is the correct choice because it accurately describes the methodology used to develop, maintain, and replace information systems for improving the quality of the software design and development process. The Software Development Life Cycle (SDLC) is a structured approach that consists of various phases, such as requirements gathering, system design, coding, testing, deployment, and maintenance. It ensures that software projects are well-planned, executed, and controlled, leading to high-quality software products. The other options, System Life Cycle (SLDC) and Program Life Cycle, do not specifically refer to the development of software systems.

Memory is the correct answer because it is the part of a computer that stores applications, documents, and system operating information. It is responsible for temporarily holding data and instructions that the CPU needs to process. There are different types of memory in a computer, such as RAM (Random Access Memory) and ROM (Read-Only Memory), which serve different purposes in storing and accessing data.

EBCDIC is the correct answer because it is an 8-bit character encoding used on IBM mainframe operating systems. ASCII is a different character encoding commonly used on modern computer systems, while UNICODE is a character encoding that supports a wide range of characters from different writing systems. UNIX is an operating system and not a character encoding.
