Test: Computer and Information Technology - 1 - Question 13

What kind of memory is ROM, and why is it essential in a computer system?

Detailed Solution for Test: Computer and Information Technology - 1 - Question 13

ROM (Read Only Memory) is a non-volatile memory type crucial for storing essential information necessary to boot and operate a computer system. Unlike RAM (Random Access Memory), which is volatile and loses its contents when the power is turned off, ROM retains its data even when the computer is shut down. This characteristic makes ROM vital for storing critical instructions and data that need to be preserved across power cycles. ROM is like a computer's long-term memory, ensuring that fundamental information is always available for the system to function properly.

Test: Computer and Information Technology - 1 - Question 14

What distinguishes Static RAM (SRAM) from Dynamic RAM (DRAM)?

Detailed Solution for Test: Computer and Information Technology - 1 - Question 14

Static RAM (SRAM) and Dynamic RAM (DRAM) are two common types of RAM with distinct characteristics. One key difference is that SRAM stores data in flip-flop circuits and does not require periodic refreshing to maintain data integrity, making it faster and more reliable than DRAM. In contrast, DRAM stores data in capacitors that need to be refreshed regularly to prevent data loss, which makes it slower but more cost-effective compared to SRAM. This fundamental distinction in how data is stored and accessed underlines the performance disparities between SRAM and DRAM in computer systems.

Test: Computer and Information Technology - 1 - Question 15

During which generation of computers were vacuum tubes primarily used as a key component?
