Final answer:
RAM, or Random Access Memory, is used to store short-term data for quick access and improve the smooth running of applications. It is typically measured in units like megabytes or gigabytes, and adding more RAM can boost a slow computer. Additionally, one byte comprises 8 bits in data storage.
Step-by-step explanation:
The primary function of RAM (Random Access Memory) is to store short-term data for quick access (option c), which aids in multitasking and running applications smoothly (option a). RAM's storage capacity is often measured in megabytes (MB) or gigabytes (GB), not gigahertz (GHz) or terabytes (TB). When a computer is running slowly and you suspect it's due to insufficient RAM, you can opt to add more RAM (option d) to improve its performance.
Furthermore, in computer data storage, a byte consists of 8 bits (option a). This measurement is fundamental when discussing digital information and computer memory, where data is stored in binary format (bits and bytes). The use of RAM in computers is a critical component of the computer's overall functions, as it provides the short-term memory necessary for the computer to operate its applications.
