مندرجہ ذیل میں سے کون سا مشترکہ یونٹ ہے جو نیٹ ورک کے ڈیٹا کی منتقلی کی شرحوں کی پیمائش کے لئے استعمال ہوتا ہے؟
A. Megabyte per second (MB's)
B. Kilobit per second (Kbps)
C. Gigahertz (GHz)
D. None of these
Check answer and explanation
Answer: Kilobit per second (Kbps)
Explanation Kilobit per second (Kbps) is a common unit for measuring network data transfer rates , especially for slower connections like older modems or for expressing smaller data streams . It represents 1,000 bits of data transferred per second.
کون سا شیڈولنگ الگورتھم سی پی یو وقت کو پروسیس کرنے کے لیے "ٹائم کوانٹم" کا استعمال کرتا ہے؟
A. Shortest Job First (SJF)
B. Round Robin (RR)
C. None of these
D. Priority Scheduling
Check answer and explanation
Answer: Round Robin (RR)
Explanation Round Robin (RR) is a CPU scheduling algorithm that assigns each process a fixed time slice called a time quantum . Each process runs for the duration of the time quantum and then moves to the end of the ready queue if it isn’t finished. It is a preemptive scheduling algorithm , meaning a process can be interrupted when its time quantum expir es.

B. The fastest memory in a computer system after CPU registers
C. The slowest memory in a computer system
D. Slower than L2 cache but faster than RAM
Check answer and explanation
Answer: Slower than L2 cache but faster than RAM
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.
Explanation The tag in HTML is used to define superscript text, which appears slightly above the normal line (e.g., x² ). Commonly used for mathematical exponents and footnote references .

A. It is a low-speed device
B. It has no memory
C. None of these
D. It is designed for processing, not permanent storage
Check answer and explanation
