rusak2 [61]

Answer: a function or procedure call from one object to another object

Explanation: UML(Unified Modeling language) behavioral modeling is the depiction of the relation of the elements in a dynamic manner and the dependency on time .Message in the UML behavioral modeling is a functional call taking place from one element to another.

The interaction is the model is seen through the flow of messages.Other options are incorrect because message is not information holding data structure, does not display the relation between object rather presents the flow and is not a memory location .

Bingel [31]

A computer is a multipurpose device that accepts input, processes data, stores data, and produces output, all according to a series of stored instructions. The central processing unit of most modern computers is a microprocessor. The instructions that tell a computer how to carry out a task are referred to as computer programs, which are distributed as software. Computers run three main types of software: Application software, system software, and development tools. An example of system software is a computer operating system, which is essentially the master controller for all the activities that a digital device performs. Digital devices are constructed using tiny electronic components that represent data bits as electrical signals. The system unit houses the system board, which contains several integrated circuits made from semiconducting materials. Computers come in three popular form factors: component, clamshell and slate. Many of today's digital devices operate on battery power supplied by Lithium ion batteries. Battery life and lifespan can be extended by following good battery management practices.

Explanation

A computer is a multipurpose device that accepts input, processes data, stores data, and produces output, all according to a series of stored instructions. Input is data or information typed, submitted, or transmitted into a computer. Processing data involves performing calculations, drawing graphs, modifying documents, and many more. Output is the result produced by a computer. Processing is handled by the computer’s CPU (Central Processing Unit) and the central processing unit of most modern computers is a microprocessor. A microprocessor executes and manages all logical instructions passed to it and performs tasks involved in computer processing. The instructions that tell a computer how to carry out a task are referred to as computer programs, which are distributed as software. A program is software or set of ordered operations on a computer that performs a particular task or function. A program is created and compiled into a language that the computer can comprehend and then distributed as software. Computers run three main types of software: Application software, system software, and development tools. Application software are programs that help a user carry out a task while a system software helps the computer system to monitor itself in order to function effectively. On the other hand, development tools are used for creating applications, operating systems, Web sites, and utilities. Digital devices are constructed using tiny electronic components that represent data bits as electrical signals. The system unit houses the system board, which contains several integrated circuits made from semiconducting materials. The essence of digital electronics is the small circuit boards and integrated circuits you see when you open up a digital device. ICs are sets of electronic circuits engraved onto a thin slide of semiconducting material. Computers come in three popular form factors: component, clamshell and slate. Form factor in computer terms refers to the size and dimensions of then device. Clamshell devices have features characterized by a keyboard as the base and a screen on the hinged cover. Those devices configured in the slate form factor have a touchscreen that covers majority of the device’s surface. Many of today's digital devices operate on battery power supplied by Lithium ion batteries. Battery life and lifespan can be extended by following good battery management practices.

The directory "a" contains its subdirectory "b" and there is no other entry in the directory "a". You want to display "the conte

Svet_ta [14]

The answer assumes that the question is about which command help accomplish display directory contents in Unix-like operating systems.

Answer:

The command is ls.

Explanation:

The command ls (short for list) displays a variety of important information in different ways regarding any directory contents. Because of this, it is probably one of the most used commands in Unix-like operating systems.

Any directory can contain directories and files of different sizes, recently created/modified, attributes like permissions for being accessed, and, with this command, we can see all this information by size, chronologically, by owner, and/or by many more ways.

In the question, we can accomplish to list that the directory "a" contains its sub-directory "b" and no other entry using the next line of code:

Command-line 1: $\\ ls\; a$ (the command "says": display content of a)

Result: $b$

The result is only the directory b because there is no other entry in it.

To display more information regarding b, we can use the many options available for the command ls, like -a (all entries), -d (only directories), -l (long listing format), and so on, e.g. ls -a A (display all entries in directory A, included hidden files).
