      Answers Explanation & Hints: The characteristic that describes PROM (Programmable Read-Only Memory) is “chips that are manufactured blank and then can be programmed once by a PROM programmer.” PROM is a type of non-volatile memory that allows for programming of data or instructions onto the chip after it is manufactured. The initial state of a PROM chip is blank, and it can be programmed with specific data or instructions using a PROM programmer device. Once the programming process is complete, the data or instructions become permanent and cannot be modified or erased. PROM retains the programmed information even when power is turned off, making it non-volatile. PROM was widely used in the past for storing firmware, boot code, and other fixed data in electronic systems. However, the main drawback of PROM is that its contents cannot be changed or updated once programmed, requiring a new chip to be used if any changes are necessary. Modern alternatives such as EEPROM (Electrically Erasable Programmable Read-Only Memory) and flash memory provide the ability to erase and reprogram the memory, offering greater flexibility and versatility. As a result, PROM chips are less commonly used in contemporary electronic systems.

44. Which characteristic describes a SIMM?

    • a small circuit board that holds several memory chips and has a 30- or 72-pin configuration
    • chips that require constant power to function and are often used for cache memory
    • chips that run at clock speeds of 800 MHz and have a connector with 240 pins
    • chips whose contents can be “flashed” for deletion and are often used to store BIOS
      

      Answers Explanation & Hints: The characteristic that describes a SIMM (Single Inline Memory Module) is “a small circuit board that holds several memory chips and has a 30- or 72-pin configuration.” A SIMM is a type of memory module used in older computer systems to expand their memory capacity. It consists of a small circuit board that houses multiple memory chips (DRAM chips) and has a specific number of pins arranged in a single row. The two common configurations for SIMMs are 30-pin and 72-pin. SIMMs were commonly used in systems like early PCs and Macintosh computers. They provided a convenient way to increase the memory capacity of the system by simply plugging the SIMM module into the corresponding memory slot on the motherboard. The number of pins on a SIMM determines the data width and capacity it supports. For example, a 30-pin SIMM typically provided 8-bit or 9-bit data width and supported lower memory capacities, while a 72-pin SIMM supported larger data widths (usually 32-bit) and higher memory capacities. However, SIMMs are no longer widely used in modern computer systems. They have been replaced by more advanced memory module designs, such as DIMMs (Dual Inline Memory Modules) and SODIMMs (Small Outline Dual Inline Memory Modules), which offer higher capacities and faster data transfer rates.

45. Which characteristic describes EPROM?

    • a chip that is nonvolatile and can be erased by exposing it to strong ultraviolet light
    • chips that run at clock speeds of 800 MHz and have a connector with 240 pins
    • chips specifically designed for video graphics that are used in conjunction with a dedicated GPU
    • chips that require constant power to function and are often used for cache memory
      

      Answers Explanation & Hints: The characteristic that describes EPROM (Erasable Programmable Read-Only Memory) is “a chip that is nonvolatile and can be erased by exposing it to strong ultraviolet light.” EPROM is a type of non-volatile memory that allows for programmability and erasability of data or instructions. It is a read-only memory chip that can be electrically programmed once, and after that, its contents remain intact even when power is turned off. What distinguishes EPROM from other types of memory is its erasability feature. EPROM can be erased and reprogrammed by exposing it to strong ultraviolet (UV) light for a specified duration. This exposure to UV light removes the charge stored in the memory cells, effectively erasing the data or instructions previously programmed onto the chip. EPROM chips typically have a transparent quartz window on the top that allows the UV light to reach the memory cells during the erasing process. The programming of EPROM is typically done using specialized programming equipment that applies electrical voltages to specific pins of the chip. Due to the requirement of ultraviolet light exposure for erasure, EPROM chips are less commonly used in modern systems compared to other types of memory that offer electrically erasable and reprogrammable capabilities, such as EEPROM (Electrically Erasable Programmable Read-Only Memory) and flash memory.

46. Which characteristic describes a SIMM?

    • a small circuit board that holds several memory chips and has a 30- or 72-pin configuration
    • SRAM that is internal and integrated into the CPU
    • a smaller, more condensed memory module that provides random access data storage, ideal for use in laptops, printers, and other devices where
    • conserving space is desirable
    • an individual memory chip that has dual rows of pins used to attach it to the motherboard
      

      Answers Explanation & Hints: The characteristic that describes a small circuit board that holds several memory chips and has a 30- or 72-pin configuration is a SIMM (Single Inline Memory Module). SRAM (Static Random Access Memory) that is internal and integrated into the CPU is a characteristic of cache memory, specifically known as CPU cache. A smaller, more condensed memory module that provides random access data storage, ideal for use in laptops, printers, and other devices where conserving space is desirable is an SODIMM (Small Outline Dual Inline Memory Module). An individual memory chip that has dual rows of pins used to attach it to the motherboard is a DIP (Dual In-Line Package).

      Answers Explanation & Hints: The characteristic that describes EPROM (Erasable Programmable Read-Only Memory) is “a chip that is nonvolatile and can be erased by exposing it to strong ultraviolet light.” EPROM is a type of non-volatile memory that retains its stored information even when power is removed. It allows for programmability and erasability, meaning that data or instructions can be written to the chip and erased as needed. EPROM chips have a transparent quartz window on the top that allows them to be erased by exposing them to strong ultraviolet (UV) light. The UV light removes the electric charge trapped in the memory cells, effectively erasing the contents of the EPROM. To program EPROM, specialized programming equipment is used to apply electrical voltages to specific pins on the chip, which stores the desired data or instructions in the memory cells. Once programmed, the data remains intact until erased by UV light. However, it’s important to note that EPROM technology has largely been replaced by more advanced and convenient alternatives, such as EEPROM (Electrically Erasable Programmable Read-Only Memory) and flash memory, which allow for electronic erasure and reprogramming without the need for UV light exposure.
