کون سا فن تعمیر ڈیٹا اور ہدایات دونوں کے لیے ایک ہی میموری کی جگہ استعمال کرتا ہے؟
-
A. RISC Architecture
-
B. CISC Architecture
-
C. Von Neumann Architecture
-
D. None of these
Explanation
- Von Neumann Architecture uses a single memory space to store both data and instructions.
- It allows the CPU to fetch instructions and data from the same memory.
- It simplifying design but possibly causing bottlenecks.
کلاؤڈ کمپیوٹنگ کی تعیناتی کی لاگت کا حساب لگانے کا صحیح فارمولا کیا ہے؟
-
A. CostCLOUD = Σ(UnitCostCLOUD / Revenue)
-
B. CostCLOUD = Σ(UnitCostCLOUD / (Revenue – CostCLOUD))
-
C. None of these
-
D. CostCLOUD = Σ(UnitCostCLOUD × (Revenue + CostCLOUD))
Explanation
CostCLOUD = Σ(UnitCostCLOUD / (Revenue – CostCLOUD)).
- This formula reflects the relationship between unit cost, revenue, and total cost in a cloud computing deployment.
- The cost is adjusted by factoring in both the unit cost and the difference between revenue and total cost.
-
A. *ptr
-
B. ptr*
-
C. None of these
-
D. ©ptr
Explanation
In C, the asterisk (*) symbol is used to dereference a pointer.
It means to access the value stored at the address held by the pointer.
Therefore, *ptr is the correct syntax to access the value at the address ptr.
کمپائلر میں انٹرمیڈیٹ کوڈ جنریشن کا مقصد کیا ہے؟
-
A. To provide a platform-independent representation of the source code
-
B. To perform lexical analysis
-
C. To produce machine code directly
-
D. None of these
Explanation
- Intermediate code allows portability across different hardware platforms.
- It serves as a bridge between high-level language and machine code generation.
-
A. 0
-
B. Undefeated behavior
-
C. 5
-
D. None of these
Explanation
- The
printf("%dn", x++); prints the value of x before incrementing it. - Since
x++ is a post-increment operator, the value of x (5) is printed first, and then x becomes 6 after the statement.
مندرجہ ذیل میں سے کون سا کلاؤڈ تعیناتی ماڈل ہے؟
-
A. Open cloud
-
B. None of these
-
C. Private cloud
-
D. Network cloud
Explanation
- A private cloud is a cloud deployment model where resources are dedicated to a single organization.
- This offering greater control and security.
- Other deployment models include public cloud, hybrid cloud, and community cloud.
مندرجہ ذیل میں سے کون سا غیر کلسٹرڈ انڈیکس کی خصوصیت ہے؟
-
A. The physical order of rows is different from the index order
-
B. None of these
-
C. It cannot be created on a table with a clustered index
-
D. The physical order of rows is same from the index order
Explanation
- A non-clustered index stores pointers to the actual data, so the physical order of rows differs from the index order.
- It allows multiple non-clustered indexes on a table and supports duplicate values.
ایک کثیر صارف ماحول میں، صارفین کے درمیان منصفانہ سی پی یو وقت کی تقسیم کو یقینی بنانے کا ایک عام طریقہ کیا ہے؟
-
A. Priority Scheduling
-
B. Shortest Job Next Scheduling
-
C. None of these
-
D. Round Robin Scheduling
Explanation
- Round Robin Scheduling allocates a fixed time slice (quantum) to each user or process, ensuring fair CPU time.
- It prevents any single process from monopolizing the CPU, making it ideal for multi-user environments.
-
A. Document
-
B. Key-Value
-
C. Relational
-
D. None of these
Explanation
- Relational databases use structured tables and SQL.
- This making them distinct from NoSQL databases.
- NoSQL types include Key-Value, Document, Column, and Graph databases.
ویب ہوسٹنگ کے لیے عام طور پر کون سا سروس ماڈل استعمال ہوتا ہے؟
-
A. None of these
-
B. PaaS
-
C. IaaS
-
D. Saas
Explanation
- Platform as a Service (PaaS) provides the tools and environment to develop, host, and manage web applications.
- It abstracts underlying infrastructure.
- It allowing developers to focus on deployment and scaling.
