True / False Exercise - Computer SySTEM

Explanation
The statement that ALU is also popularly known as a microprocessor is false. ALU, which stands for Arithmetic Logic Unit, is a component of a microprocessor. It is responsible for performing arithmetic and logical operations on data. A microprocessor, on the other hand, is a complete processing unit that consists of multiple components, including the ALU, control unit, and registers. Therefore, while ALU is an essential part of a microprocessor, it is not the same as a microprocessor itself.

Explanation
Program instructions written in a high-level language are called source code because source code is the human-readable version of the program that is written using a high-level language. High-level languages are designed to be easier for humans to understand and write, and the source code serves as the input to a compiler or interpreter, which translates the high-level code into machine code that can be executed by a computer. Therefore, the statement "Program instructions written in a high-level language are called source code" is true.

Explanation
ROM (Read-Only Memory) is a type of computer memory that is only capable of being read and not written to. It is non-volatile, meaning that its contents are retained even when the power is turned off. Unlike Random Access Memory (RAM), ROM cannot be written to or modified once it has been programmed during manufacturing. Therefore, the statement "ROM can be written too" is false.

Explanation
GNU/Linux is indeed an open source operating system. It is a combination of the GNU operating system and the Linux kernel. The term "open source" refers to the fact that the source code of the operating system is freely available to the public, allowing users to view, modify, and distribute it as they see fit. This openness promotes collaboration, transparency, and innovation within the software community. Many individuals and organizations have contributed to the development and improvement of GNU/Linux, making it a popular choice for servers, desktops, and embedded systems.

Explanation
The statement is true because CPU (Central Processing Unit) is indeed popularly known as a microprocessor. The CPU is the main component of a computer system that carries out instructions and performs calculations. It is often referred to as a microprocessor because it is a small chip that contains all the necessary components for processing data and executing instructions.

Explanation
Freeware refers to software that can be used without any monetary cost. This means that users can access and utilize the software without having to pay for it. Therefore, the given statement that freeware is available for use at no monetary cost is true.

Explanation
Primary storage, also known as main memory or RAM, is a type of computer memory that is directly accessible to the CPU. It is used to store data and instructions that are currently being processed by the CPU. However, primary storage is volatile, meaning that its contents are lost when the computer is powered off or restarted. Therefore, primary storage is temporary and not designed for long-term storage of data.

Explanation
Secondary storage is not contained in the CPU. The CPU, or central processing unit, is the primary component of a computer that carries out instructions and performs calculations. Secondary storage refers to external devices such as hard drives, solid-state drives, and optical discs, which are used for long-term storage of data. These storage devices are separate from the CPU and are connected to it through input/output interfaces. Therefore, the statement that secondary storage is sometimes contained in the CPU is false.

Explanation
The given statement is true. Object code refers to the machine code that is generated by a compiler after translating the source code. It consists of binary instructions that can be directly executed by the computer's processor. This object code is specific to the target machine architecture and can be directly loaded and executed by the computer. Therefore, the statement accurately describes the process of translating source code into machine language through a compiler.

Explanation
DVDs have a higher storage capacity than CD-ROMs because they are designed to store more data. DVDs use a different technology called digital versatile disc, which allows for higher data density and larger storage capacity compared to CD-ROMs. This increased storage capacity makes DVDs a preferred choice for storing larger files, such as movies, videos, and software programs.
