Question: Why does a computer need an operating system?

An operating system (OS) is a software program that manages the hardware and software resources of a computer. The OS performs basic tasks, such as controlling and allocating memory, prioritizing the processing of instructions, controlling input and output devices, facilitating network communication, and managing files.


Without an operating system, a computer would not be able to function. The OS acts as an interface between the user and the hardware, allowing the user to run applications and perform tasks on the computer. The OS also provides security and stability, preventing unauthorized access and ensuring that the system can recover from errors.


There are different types of operating systems, such as Windows, Linux, macOS, Android, iOS, etc. Each OS has its own features, advantages, and disadvantages. Some OSs are designed for specific purposes, such as embedded systems, servers, or mobile devices. Some OSs are more user-friendly, while others are more customizable and flexible.


The choice of an operating system depends on the user's needs, preferences, and budget. However, regardless of the type of OS, every computer needs one to function properly and efficiently.

सवाल: अज्ञेय का वैवाहिक जीवन उतार-चढ़ाव भरा था, वर्णन कीजिए? अज्ञेय का वैवाहिक जीवन उतार-चढ़ाव भरा था। उन्होंने दो विवाह किए, लेकिन दोनों विवाह सफल नहीं हो पाए। उनका पहला विवाह 1937 में राजकुमारी रत्नलता से हुआ था। यह विवाह अज्ञेय के परिवार की इच्छा के विरुद्ध था। अज्ञेय के पिता हीरानंद वात्स्यायन संस्कृत के विद्वान थे और वे चाहते थे कि अज्ञेय एक योग्य विदुषी से विवाह करें। रत्नलता एक साधारण परिवार से थीं और वे संस्कृत नहीं जानती थीं। इस कारण से, अज्ञेय के परिवार वालों ने इस विवाह का विरोध किया। अज्ञेय और रत्नलता का विवाह कुछ वर्षों तक चलता रहा, लेकिन अंततः उनका तलाक हो गया। इस तलाक के कई कारण थे, जिनमें अज्ञेय की व्यस्त जीवनशैली, रत्नलता की शिक्षा और सामाजिक पृष्ठभूमि में अंतर, और अज्ञेय के परिवार का विरोध शामिल था। अज्ञेय का दूसरा विवाह 1956 में कपिला मलिक से हुआ था। कपिला एक मशहूर संगीतकार थीं और वे अज्ञेय की साहित्यिक प्रतिभा की प्रशंसक थीं। यह विवाह कुछ वर्षों तक चलता रहा, लेकिन अंततः यह भी विफल हो गया। इस विफलता के कारणों में अज्ञेय के व्यस्त जीवनशैली, कपिला की स्वतंत्रताप्रियता,...

Question: Explain voter apathy indifference among the youth considered a challenge for south africa democracy?  Voter apathy and indifference among the youth pose significant challenges to South Africa's democracy. When young people disengage from the electoral process, it undermines the representativeness and legitimacy of the government. Low youth voter turnout means that the voices and concerns of young South Africans are underrepresented in policymaking, leading to policies that may not adequately address issues crucial to them, such as unemployment, education, and access to healthcare. This lack of participation can also empower special interests and entrenched elites, further marginalizing young people's voices in the political process.

Silence and Stigma Around Sexual Violence – Many victims fear speaking out due to societal stigma, allowing abuse to go unreported and perpetrators to continue their actions...
