Question Discussion & Solution

The correct answer is an operating system.

• Linux is an operating system.

Key Points

• Linux was created in 1991 by  Linus Torvalds and the Free Software Foundation (FSF).
  • It is an open-source Unix-like operating system.
  • An operating system help users interact with the computer.

Additional Information

• Machine language and Assembly language are an example of a low-level language.
  • Machine language is a low-level language that is comprised of binary digits i.e. ones and zeros. 
  • An assembly language is a language designed for a specific type of processor.

The correct answer is Machine Language.

Key Points

• Low-level languages are also known as Machine Language.
• A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture commands or functions in the language map closely to processor instructions.
• Generally, this refers to either machine code or assembly language.

Additional Information

• Examples of low-level programming languages:
  • C and C++ are now considered low-level languages because they have no automatic memory management. 
• Low-level languages were developed first, and high-level languages came along later.
• High-level languages are more easily understood by humans mostly coding languages like Java.

The correct answer is HTTPS.

• HTTPS(HyperText Transfer Protocol Secure): is an application layer protocol and used for secure communication over the internet.

Additional Information

• HTTP (HyperText Transfer Protocol): is an application layer protocol designed to transfer information between networked devices and runs on top of other layers of the network protocol stack. HTTP involves a client machine making a request to a server, which then sends a response message and communication between web browsers and web servers. HTTP is a stateless protocol.
• SMTP (Simple Mail Transfer Protocol): is an application layer protocol and used to send emails over the internet. SMTP is a state-full protocol.
• TCP/IP (Transmission Control Protocol/ Internet Protocol) is the communication protocol is used by the internet and used to interconnect network devices on the internet. Its routing function enables internetworking and essentially establishes the Internet.
• TCP is responsible for the data delivery of a packet and IP is responsible for the logical addressing. 
• FTP (File Transfer Protocol):  is an application layer protocol and used to exchange files on the internet and copy large files from a remote computer to the requesters' computer.

The correct answer is Paint Brush.

Key Points

• BASIC:
  • This programming language was first designed by John G. Kemeny and Thomas E. Kurtz in 1964.
  • The full form of BASIC is - Beginner's All-Purpose Symbolic Instruction Code.
  • It is generally used for scientific and engineering operations.
  • The introduction of newer machines with far greater capabilities made this language nearly obsolete and its upgraded version called Visual BASIC was released by Microsoft in 1991.
• ​C++:
  • ​The programming language was created by Bjarne Stroustrup in the mid-1980s as an extension to the C language.
  • It is an object-oriented language having two main components - direct mapping of hardware and zero-overhead abstractions.
  • The other languages like Java etc were influenced by C++.
• ​JAVA:
  • ​The programming language was designed by James Gosling at Sun Microsystems and was first released in the year 1995.
  • Java language is not platform-dependent and can be used to develop android applications.
  • The most recent version of Java, i.e. Java SE 16 got released in March 2021.
• PAINT BRUSH:
  • Paint is software that enables users to create basic graphic art on their systems.
  • The software has been developed by Microsoft and is found in all the versions of Microsoft Windows.
  • Recently in April 2021, Microsoft has made Microsoft Paint updateable from the Microsoft Store.

The correct answer is Gigahertz.

Key Points

• The speed of the CPU is measured in Gigahertz.
  • A central processing unit or CPU enables your computer to interact with all of the applications and installed programmes.
  • CPU interprets the program’s instructions and creates the output that is the interface.
  • The performance of the CPU has a major effect on the speed at which programs run.
  • Clock speed (also “clock rate” or “frequency”) is an important attribute to measure the performance of a processor. 
  • A higher clock speed means a faster CPU.  
  • The CPU processes many instructions from different programs every second.
  • The clock speed measures the number of cycles the CPU executes per second.
    • ​It is measured in GHz (gigahertz).
  • A “cycle” is technically a pulse synchronized by an internal oscillator.
  • During each cycle, billions of transistors within the processor open and close.
  • A CPU with a clock speed of 3.2 GHz executes 3.2 billion cycles per second.
