Smalltalk Basic Programming Test

Smalltalk codes are stored in the virtual machine in byte-code form. Byte-code is a low-level representation of the Smalltalk code that can be executed by the virtual machine. It is a compact and efficient form of representation that allows for faster execution of the code. By storing the code in byte-code form, the virtual machine can interpret and execute the Smalltalk code more efficiently, resulting in improved performance.

Smalltalk was created at PARC, which stands for Palo Alto Research Center. PARC is a research and development company located in Palo Alto, California. It is well-known for its contributions to the development of modern computing technologies, including the creation of the Smalltalk programming language. Smalltalk was developed in the 1970s by a team led by Alan Kay at PARC, and it is considered one of the first object-oriented programming languages.

Smalltalk supports single inheritance. This means that a class can only inherit from a single superclass. In other words, each class in Smalltalk has only one direct parent class. This type of inheritance allows for a simpler and more straightforward class hierarchy, as compared to multiple inheritance where a class can have multiple parent classes.

The first stable version of Smalltalk was released in 1980. This means that the software reached a point where it was considered reliable and ready for use by the public. It is important to note that Smalltalk is a programming language and environment that was developed at Xerox PARC in the 1970s. Its release in 1980 marked a significant milestone in the history of programming languages.

The metaclass was added in Smalltalk 80.

Smalltalk is executed by a virtual machine as Java. Smalltalk is a dynamic, object-oriented programming language that was designed to be executed on a virtual machine. The Smalltalk virtual machine is written in Java, which allows Smalltalk code to run on any platform that supports Java. This makes it easier to develop and deploy Smalltalk applications, as they can be run on a wide range of devices and operating systems.

The correct answer is "Image." In Smalltalk programming, an "Image" file contains all the Smalltalk code. This file includes the entire state of the Smalltalk system, including classes, methods, and objects. It is used to save and load the Smalltalk environment, allowing developers to easily save their work and resume it later. The Image file is a crucial component of Smalltalk development as it ensures the persistence and portability of the codebase.

Smalltalk was first released as Smalltalk 80. This indicates that Smalltalk was initially released in the year 1980. The numbering system represents the version of Smalltalk, with Smalltalk 80 being the specific version that was released initially.

Squeak was derived from Version 1 of Smalltalk.

The correct answer is Object-oriented. Smalltalk is a programming language that follows the object-oriented programming paradigm. It emphasizes the use of objects, which are instances of classes, to represent and manipulate data. In Smalltalk, everything is an object, and interactions between objects occur through message passing. This paradigm allows for encapsulation, inheritance, and polymorphism, enabling the creation of modular and reusable code.
