Answer:

Basic:

Creator: John G. Kemeny and Thomas E. Kurtz

Date Created: 1964

Motivation: Kemeny and Kurtz developed Basic as a simple programming language for use in teaching computer science to non-science students at Dartmouth College. They wanted to create a language that was easy to learn and use, and that would allow students to write simple programs to solve mathematical problems.

C:

Creator: Dennis Ritchie

Date Created: 1972

Motivation: C was developed as a systems programming language at Bell Labs, primarily to create the UNIX operating system. Ritchie and his team wanted to create a language that was high-level enough to be easy to use, but low-level enough to give the programmer fine-grained control over the computer's hardware and resources.

Java:

Creator: James Gosling, Mike Sheridan and Patrick Naughton

Date Created: 1995

Motivation: Java was developed at Sun Microsystems as a platform-independent programming language for use in consumer electronic devices such as cable set-top boxes, video game consoles, and other embedded systems. The team wanted to create a language that would be easy to write, run, and maintain, and that would be portable across different platforms and devices.

Python:

Creator: Guido van Rossum

Date Created: 1989

Motivation: Python was developed by van Rossum as a high-level programming language for general-purpose use. He wanted to create a language that was easy to read and write, and that would be well-suited for a wide range of tasks, such as web development, scientific computing, and data analysis.

The programming languages Basic, C, Java and Python were created by John G. Kemeny and Thomas E. Kurtz, Dennis Ritchie, James Gosling, and Guido van Rossum respectively. Their motivations ranged from facilitating non-science students to access computing, system developments, a platform-agnostic design, to creating a language easy to read and write.

The programming language Basic was created by John G. Kemeny and Thomas E. Kurtz in the mid-1960s at Dartmouth College to provide computer access to non-science students. It was designed with simplicity and universality in mind.

C language was developed by Dennis Ritchie at Bell Labs in the early 1970s. The main motivation behind the development of the 'C' language was to facilitate the development of the Unix operating system.

Java was created by James Gosling from Sun Microsystems (Sun) in 1995. The primary motivation was to design a language that could be used on various platforms, for multiple types of devices (computers, mobile phones, televisions etc). This led to the 'Write Once, Run Anywhere' concept.

Python was created by Guido van Rossum and first released in 1991. Rossum's primary goal in creating Python was to make it the easiest language to read and write.

In question 6, if a computer is upgraded from Windows 10 Professional to Windows Server 2019, it can now support the Domain-based networking model that it could not support without the upgrade.

The Domain-based networking model is a centralized model in which a central server called a domain controller is used to authenticate and authorize network access. This model is typically used in larger organizations and it requires the use of a server operating system like Windows Server.

Windows 10 Professional does not have the capabilities to act as a domain controller, but Windows Server 2019 does.

With the upgrade to Windows Server 2019, the computer can now function as a domain controller and support the Domain-based networking model, allowing for centralized management and control of network access. It also supports other advanced features like active directory, group policy management, and domain name system (DNS) integration, which are not present in Windows 10 Professional.

A multiple-mode fiber optic cable uses multiple rays of light running at different angles to transmit data.

what is multiple-mode fiber optic?

Multi-mode fiber is a type of optical fiber designed to carry multiple light rays or modes simultaneously, each at a marginally different reflection angle inside the optical fiber core.

Multi-mode fiber is mainly used to transmit across comparatively shorter distances, as the modes are more likely to disperse over longer extents. This phenomenon is known as modal dispersion. Another common type of optical fiber is the single-mode fiber which is used mainly for longer distances.

Single mode fiber is designed to propagate a single light mode whereas multimode supports multiple simultaneous light modes. This difference impacts bandwidth, signal transmission distance and signal stability which we'll explore later.

To transmit data, a multiple-mode fiber optic cable makes use of multiple rays of light that run at different angles.

Option A is correct.

A type of optical fiber called multimode fiber is made to carry multiple light rays or modes at slightly different reflection angles inside the core of the fiber. Because the modes are more likely to disperse over longer distances, multi-mode fiber is typically utilized for transmitting over relatively shorter distances. Modal dispersion is the name given to this phenomenon. The single-mode fiber, which is primarily utilized over longer distances, is an additional common type of optical fiber.

Multimode fiber supports multiple simultaneous light modes, whereas single mode fiber is designed to propagate a single light mode. We'll look later at how this difference affects signal stability, signal transmission distance, and bandwidth.
