The more RAM a computer has, the faster it can process data.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Having more RAM in a computer allows it to store more data that it can quickly access, which in turn improves the processing speed. When a computer runs out of RAM, it starts using the slower hard drive as virtual memory, resulting in slower performance. Therefore, increasing the amount of RAM in a computer can significantly enhance its processing speed by reducing the need for accessing slower storage devices.Rate this question:

Data are stored permanently in RAM.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given statement is incorrect. Data is not stored permanently in RAM (Random Access Memory). RAM is a volatile memory where data is temporarily stored while the computer is running. Once the power is turned off, the data stored in RAM is lost. For permanent storage of data, other non-volatile storage devices like hard drives or solid-state drives are used.Rate this question:

Dial-up connections transmit data at a faster rate than broadband connections.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false. Dial-up connections transmit data at a slower rate than broadband connections. Dial-up connections use a standard telephone line to connect to the internet, which has a maximum speed of 56 kilobits per second (Kbps). On the other hand, broadband connections use technologies like DSL, cable, or fiber-optic, which can provide much higher speeds ranging from several megabits per second (Mbps) to gigabits per second (Gbps). Therefore, broadband connections are generally faster than dial-up connections.Rate this question:
