What is the primary function of memory in a computer system?

Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -1 - Question 1
In a computer system, memory primarily serves as a storage system for data. When data is processed, it needs to be stored temporarily for the computer to access and utilize it efficiently. This enables the computer to carry out various tasks effectively by retrieving and storing data as needed.

What are the two primary types of memory in a computer system?

Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -1 - Question 2
The two primary types of memory in a computer system are Primary Memory and Secondary Memory. Primary Memory, also known as main memory, is used for temporary storage of data that the CPU is currently processing. Secondary Memory, on the other hand, provides long-term storage for data that needs to be retained even when the computer is powered off. Both types of memory play crucial roles in the overall functioning of a computer system.

In a computer system with 64k words, how many cells would the memory unit typically contain?

Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -1 - Question 3
In a computer system with 64k words, the memory unit would typically contain 64*1024=65536 cells. Each of these cells is assigned a unique address ranging from 0 to 65535, allowing the computer to organize and access data efficiently within the memory structure. This addressing scheme enables the computer to manage large volumes of data effectively during processing and storage operations.

Which type of memory retains its contents even when the power is turned off?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -1 - Question 4
ROM (Read-only Memory) is the type of memory that retains its contents even when the power is turned off. Unlike volatile memory like RAM, ROM stores information that cannot be changed once it's been programmed. It typically contains startup instructions for computers and is used in various electronic devices and computers. Modern types like PROM and EPROM can be erased and reprogrammed multiple times, but they are still referred to as ROM due to their non-volatile nature.

What is the key difference between RAM (Random Access Memory) and ROM (Read-only Memory)?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -1 - Question 5
The key difference between RAM and ROM lies in the type of data they store. RAM (Random Access Memory) stores the data that the computer needs right now, akin to the short-term memory in your brain. It is volatile and loses data when the power is turned off. On the other hand, ROM (Read-only Memory) stores information that cannot be changed once programmed. It typically includes startup instructions and is non-volatile, retaining its contents even when the power is off.

What is the distinguishing feature of EPROM that sets it apart from PROM?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -1 - Question 6
EPROM stands out from PROM due to its unique ability to be erased using ultraviolet light, which allows for reprogramming. This distinctive feature enables EPROM to retain data until it is exposed to ultraviolet light, resetting it for reprogramming. This quality makes EPROM a valuable component in various electronic devices, as it offers the flexibility of multiple writes and erasures, facilitating adjustments and updates even after initial programming.

What is the key difference between PROM and ROM in terms of their initial state?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -1 - Question 7
The primary distinction between PROM and ROM lies in their initial states. PROM begins as a blank memory chip, allowing users to program it with data as needed. In contrast, ROM is pre-programmed during the manufacturing process, with its contents being fixed and unchangeable once produced. This fundamental difference in their initial states affects how these memory technologies are utilized in various electronic devices.

What is the primary purpose of secondary storage devices in a computer system?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -1 - Question 8
Secondary storage devices in a computer system are designed to store large amounts of data permanently. Unlike primary memory (RAM) which is volatile and temporary, secondary storage retains data even when the power is off. This type of storage is essential for long-term data storage and archiving purposes in a computer system.

Which type of memory device uses light to store data?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -1 - Question 9
Optical Memory devices, such as CDs, DVDs, and Blu-ray discs, utilize light to store data. These discs have tiny bumps and dips that a laser reads to access the stored information. This technology allows for relatively large storage capacities and is commonly used for media distribution and archival purposes.
