ڈیٹا کی منتقلی کے لیے کمپیوٹر کا کون سا حصہ استعمال ہوتا ہے؟
A. Software parts
B. Physical parts
C. None of these
D. Both A and B
Check answer and explanation
Answer: Both A and B
Explanation Both software and physical parts work together to transfer data in a computer system. Software parts , such as operating systems, device drivers, and data transfer protocols, manage and direct data transfer. Physical parts , like buses, ports, cables, network interface cards, and storage devices, physically move the data.

ابتدائی غیر اتار چڑھاؤ والی یادوں میں سب سے طویل رسائی کے لیے میموری کی کون سی قسم مشہور ہے؟
A. Magnetic Bubble Memory
B. DRAM
C. SRAM
D. Flash Memory
Check answer and explanation
Answer: Magnetic Bubble Memory
Explanation Magnetic Bubble Memory was an early non-volatile memory technology from the 1970s That stored data as magnetic domains ("bubbles") in a thin film of magnetic material. It was a mechanically addressed system, and data access involved physically moving the bubbles past a read/write head
ٹیبل میں کسی ریکارڈ کو منفرد طور پر پہچاننے کے لیے کس کی کی ضرورت ہوتی ہے؟

A. y will be converted to int and z will be calculated as int
B. z will be converted to long and z will be calculated as int
C. z will be converted to long and z will be calculated as long
D. Compiler will generate error
Check answer and explanation
Answer: y will be converted to int and z will be calculated as int
Explanation In z = z + y;, since z is an int and y is long , y is converted to int (if possible) to match the type of z due to usual type conversion rules. The result is calculated as an int, and this may cause data loss if y exceeds int range.
تیسری جنریشن والی کمپیوٹر میں کونسی ٹیکنالوجی کا استعمال ہوا تھا؟
A. Transistors
B. Integrated circuits
C. Artificial Intelligence
D. Vacum Tubes
Check answer and explanation
Answer: Integrated circuits
Explanation An integrated circuit is a small chip of semiconductor material, typically silicon , that contains numerous tiny MOSFETs. The five generations of computers: First Generation (1946-1959 or 1940-1956): Vacuum tube-based technology (e.g., ENIAC). Second Generation (1959-1965 or 1956-1963): Transistor-based technology. Third Generation (1965-1971 or 1964-1971): Integrated circuit -based technology. Fourth Generation (1972-1980): VLSI microprocessor-based technology. Fifth Generation (1980-present): ULSI microprocessor-based technology, with a focus on artificial intelligence.
