What read/write memory is used that is faster than RAM but expensive and limited in size?

Cache memory operates between 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to a CPU request. The name of the actual hardware that is used for cache memory is high-speed static random access memory (SRAM).

Which technique is used to optimize performance of virtual memory?

Segmentation is also used to manage virtual memory. This approach divides virtual memory into segments of different lengths. Segments not in use in memory can be moved to virtual memory space on the hard drive.

What is short term memory in computer?

RAM is your computer’s short-term memory. In contrast, a computer’s hard disk or SDD is its long-term memory, where things are stored more or less permanently.

Why integers are better than float?

Integers and floats are two different kinds of numerical data. An integer (more commonly called an int) is a number without a decimal point. A float is a floating-point number, which means it is a number that has a decimal place. Floats are used when more precision is needed.

Why is memory optimization important?

When a computer or software has a finite amount of memory, many issues can arise when that memory isn’t used efficiently. That’s why memory optimization is critical for better overall performance.

What is virtual memory discuss the benefits of virtual memory techniques?

The main visible advantage of this scheme is that programs can be larger than physical memory. Virtual memory serves two purposes. First, it allows us to extend the use of physical memory by using disk. Second, it allows us to have memory protection, because each virtual address is translated to a physical address.

Why is short term memory called working memory?

They both do not hold information for very long but short term memory simply stores information for a short while, while working memory retains the information in order to manipulate it.

What is the difference between a short and a long memory?

Depending on the computer but in most cases a “short” is two bytes a “long” is four bytes and an “int” can be two or four bytes. It is important in programs that you declare it short or long if you know exactly how big the number is going to be and how often it is going to modified so that you can save as much memory as possible.

What is the difference between a short and a long int?

now usually these are referenced with int after them but it is not required. The main difference between them is their size. Depending on the computer but in most cases a “short” is two bytes a “long” is four bytes and an “int” can be two or four bytes.

What are the benefits of using integers instead of Longs?

So, the benefit is in reduced memory space. An Integer takes up half the memory that a Long does. Now, we are talking about 2 bytes, so it’s not going to make a real difference for individual integers, it’s only a concern when you are dealing with TONS of integers (e.g large arrays) and memory usage is critical.

What is the advantage of using short integers in an array?

When using short in an array or in arithmetic operations, the short integer is converted into int, and so this can introduce a hit on the speed in processing short integers Using short can conserve memory if it is narrower than int, which can be important when using a large array
