جب یہ باہر کی طرف سفر کرتا ہے تو سگنل کی توانائی کا نقصان ______ کہلاتا ہے؟
A. None of these
B. Distortion
C. Cross talk
D. Attenuation
Check answer and explanation
Answer: Attenuation
Explanation Attenuation refers to the loss of signal strength as it travels through a medium, causing the signal to weaken over distance. It is commonly seen in electrical signals , where the energy diminishes due to resistance or interference .
مواصلات کے نظام میں ، کم سگنل ٹو شور کا مطلب ______ ہے؟
A. Noise strength is good as compared to signal
B. Neither noise nor signal strength is good
C. Signal strength is good as compared to noise
D. Both noise and signal strength are good
Check answer and explanation
Answer: Noise strength is good as compared to signal
Explanation A low Signal-to-Noise Ratio (SNR) means that noise is stronger than the signal, leading to poor clarity and potential distortion in communication. A higher SNR indicates a stronger signal relative to noise, resulting in clearer communication.
Explanation Star Topology is a network layout where all devices are connected to a central hub. Node refers to any device connected to a network, such as a computer or router.
Explanation The UNIX operating system was originally developed in assembly , but later rewritten in C to make it portable. This marked a major milestone in OS development , allowing UNIX to run on different hardware platforms.
Explanation An integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material, usually silicon. Large numbers of tiny MOSFETs integrate into a small chip. First generation (1940 - 1956) vacuum tubes as a major piece of technology. The ENIAC is example of 1st generation computer. Second generation (1956 - 1963) use of transistors . Third generation (1964 - 1971) use of Integrated circuits. Fourth generation (1972 - 2010) use of the microprocessor Fifth generation (2010 to present) use Artificial intelligence
کمپیوٹر پر ونڈوز 10 انسٹال کرنے کے لیے کم از کم کتنی اسٹوریج درکار ہوتی ہے؟
A. 32 GB
B. 64 GB
C. None of these
D. 16 GB
Check answer and explanation
Answer: 32 GB
Explanation Windows 10 requires minimum 32 GB storage for installation. Earlier versions required less , but updates increased the requirement. This space is needed for system files and updates . More storage is recommended for smooth performance . It is a widely used operating system globally. Last verified on 12-04-2026
Explanation False negatives (FN) occur when the model misses positive cases . Reducing FN usually means the model is more likely to predict positive . This increases true positives (TP) b ut also can increase false positives (FP) .
Explanation MPEG stands for Moving Picture Experts Group. It's a group that develops international standards for compressing, processing, and representing audio, video, and other multimedia.
