Yang termasuk ke dalam memori bebas adalah…..
- A.
ROM
- B.
EPROM
- C.
RAM
- D.
EEPROM
Correct Answer
C. RAMExplanation
RAM (Random Access Memory) is a type of computer memory that can be read from and written to. It is considered as a form of "free memory" because it can be accessed randomly by the computer's processor, allowing for quick data retrieval and manipulation. Unlike ROM (Read-Only Memory) and other types of memory mentioned in the options, RAM can be modified and is volatile, meaning its contents are lost when the power is turned off. Therefore, RAM is the correct answer as it fits the criteria of being a type of free memory.Rate this question:

Terdapat dua cara menempatkan informasi ke dalam memori kerja. Cara tersebut adalah :
- A.
Contiguous Allocation dan Paging
- B.
Contiguous Allocation dan Non Contiguous Allocation
- C.
Non contigous Allocation dan segmentasi
- D.
Paging dan segementasi
Correct Answer
B. Contiguous Allocation dan Non Contiguous AllocationExplanation
Contiguous allocation refers to a memory management technique in which each process is allocated a contiguous block of memory. This means that the entire process is stored in a single continuous block of memory. On the other hand, non-contiguous allocation is a memory management technique where a process is divided into multiple non-contiguous blocks of memory. Each block can be located anywhere in the memory. Therefore, the correct answer states that there are two ways to place information in the working memory: contiguous allocation and non-contiguous allocation.Rate this question:

- A.
Contiguous Allocation
- B.
Non Contiguous Allocation
- C.
Segmentasi
- D.
Paging
Correct Answer
D. PagingExplanation
Paging is a memory management technique where the memory is divided into fixed-size blocks called pages. Similarly, the information or tasks in the backing store are divided into smaller units called frames. This allows for efficient allocation and management of memory as the pages can be easily swapped in and out of the frames. Therefore, paging is the correct answer as it best fits the given definition of dividing memory and backing store into smaller units.Rate this question:

Pemindahan proses dari memori utama ke disk dan sebaliknya disebut juga sebagai…..
- A.
System Buddy
- B.
Swapping
- C.
Embedded system
- D.
Controller
Correct Answer
B. SwappingExplanation
Swapping refers to the process of moving data between the main memory and the disk. This process is commonly used when the main memory becomes full and needs to free up space for other programs or data. Swapping allows the operating system to temporarily transfer less frequently used data from the main memory to the disk, making room for more important or frequently accessed data. When the swapped data is needed again, it can be brought back into the main memory from the disk.Rate this question:
