Memory clock frequency of 100 MHz, DDR3 SDRAM gives a maximum transfer rate of:
Correct Answer
B. 6400 MB/s
Explanation
DDR3 SDRAM stands for Double Data Rate 3 Synchronous Dynamic Random-Access Memory. The memory clock frequency of 100 MHz indicates that the data is transferred twice per clock cycle. Therefore, the effective transfer rate is calculated by multiplying the memory clock frequency by 2. So, 100 MHz x 2 = 200 million transfers per second. Since DDR3 SDRAM transfers 8 bytes of data per transfer, the maximum transfer rate is 200 million transfers per second x 8 bytes = 1600 million bytes per second. Converting this to megabytes, we get 1600 million bytes per second / 1000 = 1600 MB/s. However, DDR3 SDRAM is capable of dual-channel operation, which doubles the transfer rate. Therefore, the maximum transfer rate is 1600 MB/s x 2 = 3200 MB/s.

8.
Which part of the computer system can be physically touched?
Correct Answer
A. Hardware
Explanation
Hardware refers to the physical components of a computer system that can be physically touched. This includes devices such as the monitor, keyboard, mouse, CPU, and memory. Unlike software, which refers to the programs and instructions that run on the computer, hardware is tangible and can be physically interacted with. Similarly, an operating system and data are not physical components of a computer system, so they cannot be physically touched.
9.
IC chips used in computers are usually made up of what?
Correct Answer
C. Silicon
Explanation
IC chips used in computers are usually made up of silicon. Silicon is a widely used semiconductor material due to its ability to conduct electricity under certain conditions. It is the main component in the manufacturing of integrated circuits, which are the building blocks of computer chips. Silicon's unique properties, such as its high melting point and ability to withstand high temperatures, make it an ideal material for creating reliable and efficient electronic devices.

One Gigabyte is approximately equal to
Correct Answer
C. 1000,000,000 bytes
Explanation
One Gigabyte is approximately equal to 1000,000,000 bytes. This is because the prefix "Giga" in the metric system represents a factor of 10^9, which means that one Gigabyte is equal to 1,000,000,000 bytes.
