Test : Computer Memory & Characterstics of Computer Memory -2 - Question 1

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

Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -2 - Question 1
The primary function of memory in a computer system is to store data and process instructions. Memory serves as a crucial component where data is stored temporarily for processing and where instructions for processing are also stored. This allows the computer to access and manipulate data quickly and efficiently during various operations.
Test : Computer Memory & Characterstics of Computer Memory -2 - Question 2

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

Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -2 - 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 typically volatile and is used to store data and instructions that are actively being processed by the CPU. Secondary Memory, on the other hand, is non-volatile and is used for long-term storage of data even when the computer is turned off.

Test : Computer Memory & Characterstics of Computer Memory -2 - Question 3

How are the addresses of cells in computer memory typically structured?

Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -2 - Question 3
The addresses of cells in computer memory typically range from 0 to the memory size minus one. For example, if a computer has 64k words, the memory unit will contain 64*1024=65536 cells, with addresses ranging from 0 to 65535. This structured addressing system allows for efficient organization and retrieval of data within the memory unit.
Test : Computer Memory & Characterstics of Computer Memory -2 - Question 4
What distinguishes ROM (Read-only Memory) from RAM in a computer system?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -2 - Question 4
ROM, or Read-only Memory, stores information that cannot be changed once it's programmed and retains its contents even when the power is off. This makes it non-volatile in nature, unlike RAM, which is volatile and loses all its data when the power is turned off.
Test : Computer Memory & Characterstics of Computer Memory -2 - Question 5
What does RAM (Random Access Memory) primarily function as in a computer system?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -2 - Question 5
RAM, or Random Access Memory, acts as a temporary storage location for the data that your computer needs at the moment. It is like the short-term memory in your brain, focusing on what is important for the current task and holding a few things at once. When RAM fills up, the computer slows down as it needs to swap out old data with new data from the hard disk, which takes more time.
Test : Computer Memory & Characterstics of Computer Memory -2 - Question 6
In a computer system, what is the significance of memory addresses ranging from 0 to the memory size minus one?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -2 - Question 6
The significance of memory addresses ranging from 0 to the memory size minus one lies in enabling efficient data retrieval within the memory unit. By structuring addresses in this manner, every cell within the memory is uniquely identified, allowing the computer system to access and manipulate data accurately and quickly during processing tasks. This addressing scheme facilitates organized storage and retrieval of data, enhancing the overall efficiency of the system.
Test : Computer Memory & Characterstics of Computer Memory -2 - Question 7
What is the primary difference between PROM and ROM memory chips?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -2 - Question 7
The key difference between PROM and ROM lies in their functionality. PROM retains its data permanently once programmed, unlike ROM, which is typically programmed during manufacturing and cannot be altered afterwards.
Test : Computer Memory & Characterstics of Computer Memory -2 - Question 8
How do DRAM and SRAM, the two main types of RAM, differ in their functioning within a computer system?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -2 - Question 8
DRAM and SRAM are two main types of RAM that serve the same purpose of providing the memory needed for a computer to run smoothly. While they function differently, both types of RAM store data temporarily for quick access by the processor.
Test : Computer Memory & Characterstics of Computer Memory -2 - Question 9
Which characteristic defines Random Access Memory (RAM) among different access modes in computer memory?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -2 - Question 9
Random Access Memory (RAM) stands out among different access modes in computer memory because data can be read from or written to any location in any order. This means that the CPU can directly access any piece of data stored in RAM without having to move through each location sequentially. This feature enables quick and random access to data, making RAM ideal for storing programs and data that require frequent and rapid access during computer operations.
Test : Computer Memory & Characterstics of Computer Memory -2 - Question 10
What distinguishes sequential access memory from random access memory in terms of data retrieval?
Detailed Solution for Test : Computer Memory & Characterstics of Computer Memory -2 - Question 10
The key distinction between sequential access memory and random access memory lies in how data retrieval occurs. Random access memory allows data retrieval in any order, meaning that the CPU can read or write data stored in RAM without following a specific sequence. On the other hand, sequential access memory requires accessing data in a specific order, moving through each location until reaching the desired one. This difference in data access methods impacts the speed and efficiency of data retrieval in various types of memory storage.
