Answer:
B. Ram
Explanation:
A random access memory (RAM) can be defined as the internal hardware memory which allows data to be read and written (changed) in a computer. Basically, a random access memory (RAM) is used for temporarily storing data such as software programs, operating system (OS), machine code and working data (data in current use) so that they are easily and rapidly accessible to the central processing unit (CPU).
Additionally, RAM is a volatile memory because any data stored in it would be lost or erased once the computer is turned off. Thus, it can only retain data while the computer is turned on and as such is considered to be a short-term memory.
There are two (2) main types of random access memory (RAM) and these are;
1. Static Random Access Memory (SRAM).
2. Dynamic Random Access Memory (DRAM).
Given a physical host machine that has four quad-core central processing units (CPUs), 16GB of random access memory (RAM), 1TB of hard drive space, and two 1Gbps network interface cards (NICs). Therefore, if we need to create four Windows 2008 servers, the first bottleneck we should upgrade is the random access memory (RAM) because it is typically the working memory that would be used by the server to store data, so they can be accessed easily and rapidly by the central processing unit (CPU).
Hence, the random access memory (RAM) may be increased from 16GB to 64GB or more depending on the client's requirements.
