- 12
- 8
- 6
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
DDR3 SDRAM (Double Data Rate 3 Synchronous Dynamic RAM) can read or write 8 words of data per clock cycle due to its 8n-prefetch architecture.
This allows higher data transfer rates compared to earlier DDR versions.
- Slower than L2 cache but faster than RAM
- The fastest memory in a computer system after CPU registers
- The slowest memory in a computer system
- Faster than L2 cache but slower than RAM
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
L3 cache is a level of CPU cache memory that is slower than L1 and L2, but still faster than main RAM.
It helps improve overall CPU performance by storing frequently accessed data shared across cores.
مندرجہ ذیل میں سے کون مقناطیسی میموری کی خصوصیت نہیں ہے؟
- Non-volatile
- Extremely reliable
- Cheap
- Read-only
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Magnetic memory (like hard drives and magnetic tapes) is read-write, not read-only — data can be both read and modified.
It is also non-volatile, reliable, and relatively cheap for storing large amounts of data.
مندرجہ ذیل میں سے کون سا غیر اثر پرنٹرز کی مثال ہے؟
- Laser jet printer

- 1’s are grouped horizontally and vertically
- 1’s are grouped diagonally
- 1’s and 0’s are grouped together
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
In Karnaugh Maps, 1's are grouped in powers of two (1, 2, 4, 8, etc.) horizontally or vertically to simplify Boolean expressions.
The goal is to minimize the number of terms by forming the largest possible groups of adjacent 1's.
ایک منطق کا گیٹ جو منطقی ضرب کو انجام دیتا ہے اسے ______ گیٹ کہا جاتا ہے۔
- XOR
- AND
- NOT
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The AND gate performs logical multiplication, outputting 1 only when all its inputs are 1.
It is also known as a conjunction gate in digital logic.
- switch
- continue
- break
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The break statement, when used inside a loop, immediately exits the loop and transfers control to the statement following the loop.
It does not terminate the entire program, only the current loop.
- Compiler will generate error
- z will be converted to long and z will be calculated as long
- y will be converted to int and z will be calculated as int
- z will be converted to long and z will be calculated as int
اس سوال کو وضاحت کے ساتھ پڑھیں
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.
