Computer OS MCQ Quiz in मल्याळम - Objective Question with Answer for Computer OS - സൗജന്യ PDF ഡൗൺലോഡ് ചെയ്യുക

The Correct Answer is Option (1) i.e A program.

• An operating system is a software or a program that manages computer hardware, software resources, and provides common services for computer programs.
• An operating system is an interface between the computer user and computer hardware.
• The dominant desktop operating system is Microsoft Windows with a market of around 82.74%, followed by macOS by Apple Inc.
• Some popular operating system include Linux operating system, Windows operating system, VMS, OS/400, macOS, etc.
• Some of the important functions of an operating system are :
  • Memory Management
  • Processor Management
  • Device Management
  • File Management
  • Security
  • Job Accounting
  • Co-ordination between other software and users.

Operating system

An Operating System (OS) is software that acts as an interface between computer hardware components and the user.

The purpose of an operating system is to provide an environment in which a user can execute programs conveniently and efficiently. 

Some examples of operating systems include Apple macOS, Microsoft Windows, Google's Android OS, Linux Operating System, and Apple iOS.

Features of the Operating system

1. Convenience: It makes computers more convenient and easy to use.
2. Efficiency: It allows the computer system resources to be used efficiently.
3. Ability to Evolve: It should be constructed in such a way as to permit the effective development, testing, and introduction of new system functions at the same time without interfering with service.
4. Throughput: It should be constructed so that It can give maximum throughput(Number of tasks per unit time).

• VHDL is a hardware programming language
• VHDL stands for VHSIC hardware description language
• It is being used for documentation, verification, and synthesis of large digital designs
• It used in electronic design automation to describe digital and mixed-signal systems such as field-programmable gate arrays and integrated circuits
• VHDL can also be used as a general purpose parallel programming language

Cloud computing is configurable shared pool of computing resources - servers, storage, databases, networking, software, analytics and more - that can be rapidly provided to users of network.

Compiler:

• In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language 
• It scans the entire program and translates the whole of it into machine code at once.
• A compiler always generates an intermediary object code.
• It will need further linking. Hence more memory is needed.
• Source code → Compiler → Machine code → Output
• Compilers are very large programs, with error-checking and other abilities.

• It is a type of translator software. For example, COBOL.

Now it is clear that compilers convert or translate high-level code to lower-level machine language in one session all at once and then save the executable object code to memory.

Therefore, option 2 is the correct answer.

To Find:

(1101)2  – (1010)2

Step 1:

Find 1's complement of (1010)2

1's complement of (1010)2 = (0101)2

Step 2:

Add 1's complement of (1010)2  with (1101)2

Step 3:

Add carry 1 to result

0010 + 1 = (0011)₂

Key Points

Event listeners and event handlers are used to handle events, such as button clicks on your page. There is a subtle difference between event listeners and event handlers: An object can only have one event handler for a specific event but it can have multiple event listeners for the event. An event listener is Perform said event. The event handler are event monitored by code.

i. Event: User interaction 

ii. Event listener: Perform said event.

iii. Event handler: Event monitored by code

Hence the correct answer is i-b, ii-a, iii-c.

The correct answer is option 1.

Key Points  Elastic traffic can adjust, over wide ranges, to changes in delay and throughput across the internet and still meet the needs of its applications. Inelastic traffic does not easily adapt, if at all, to changes in delay and throughput across the internet. The prime example is real-time traffic, such as voice and video.

  Elastic traffic has the ability to make adjustments to wide-ranging changes in delay and throughput across the internet and still meets the needs of the applications. It adjusts its throughput between end hosts in response to network conditions. Network load or congestion may cause packet loss.

Hence the correct answer is Elastic traffic.

Additional Information

• Inelastic traffic is vulnerable to delay – it cannot be spread in time. This kind of traffic is associated with applications, which use RTP protocol. The main services that generate inelastic traffic are VoIP, VoD, IPTV, audio- and videoconference.
• Internet traffic is the flow of data within the entire Internet, or in certain network links of its constituent networks.

• Hyper Text Markup Language is the standard markup language for creating web pages and web applications.
• Web browsers receive HTML documents from a web server or local storage that are rendered into multimedia web pages.
