EEPROM is
-
ROM that cannot be re-written
-
ROM that can be written many times
-
ROM that can be erased with UV light
-
ROM that can never be written
Correct Answer
A. ROM that can be written many timesExplanation
The correct answer is "ROM that can be written many times." EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It is a type of non-volatile memory that can be electrically erased and reprogrammed. Unlike traditional ROM, EEPROM allows for multiple write operations, making it a versatile and flexible storage option for various applications.Rate this question:

8088
Correct Answer
A. 8088Explanation
The 8088 processor was indeed used in the original IBM PC. The IBM PC, released in 1981, was one of the first personal computers to become widely popular, and it used the 8088 processor as its central processing unit (CPU). The 8088 was a 16-bit microprocessor and played a significant role in the early development of personal computers. It had a clock speed of 4.77 MHz and was capable of executing a wide range of tasks, making it a suitable choice for the original IBM PC.Rate this question:

The transistor is important to digital electronics because:
-
It provides a switching mechanism to enable binary on/off processing
-
It amplifies the input current
-
It filters the current coming out of the power supply
-
It resists static electricity
Correct Answer
A. It provides a switching mechanism to enable binary on/off processingExplanation
The transistor is important to digital electronics because it provides a switching mechanism to enable binary on/off processing. Transistors can be used as electronic switches, allowing current to flow or not flow depending on the input signal. This binary on/off capability is fundamental to digital processing, where information is represented in the form of binary digits (bits). By controlling the flow of current through transistors, digital devices can perform calculations, store data, and execute logical operations.Rate this question:

Static RAM is
-
RAM that is resistant to static electricity
-
RAM that requires electrical refreshing constantly
-
RAM that does not require electrical refreshing
-
RAM that is static in content; it cannot be overwritten
Correct Answer
A. RAM that does not require electrical refreshingExplanation
Static RAM (SRAM) is a type of RAM that does not require constant electrical refreshing. Unlike dynamic RAM (DRAM), which needs to be refreshed periodically to maintain data integrity, SRAM can hold data as long as power is supplied to it. It is called "static" because the data remains static or unchanged until it is overwritten. SRAM is faster and more expensive than DRAM but is commonly used in cache memory and other applications where speed and stability are crucial.Rate this question:
