Computer Memory and Storage

Blu-ray discs have the highest storage capacity among these options. A standard Blu-ray can store 25GB (single-layer) or 50GB (dual-layer). DVDs store 4.7GB (single-layer) or 8.5GB (dual-layer). CDs store about 700MB. Floppy diskettes store only 1.44MB. Blu-ray's capacity significantly exceeds the other formats.

Common DVD drive types include DVD-RW (rewritable), DVD+RW (another rewritable format), and DVD-RAM (a random-access rewritable format). DVD-RD is not a standard DVD drive type - it appears to be a fabricated or incorrect term. Real DVD types include ROM, R, RW, RAM, and combinations like DVD+RW/-RW.

Cache is a type of high-speed memory that stores frequently used data for quick access. PS (power supply), DSP (Digital Signal Processor), and FLOPS (Floating Point Operations Per Second - a performance measure) are not directly related to memory. Cache memory is essential for CPU performance.

ROM (Read-Only Memory) is a type of computer memory that can only be read from and not written to after manufacture. Unlike RAM (which can be both read and written), ROM contains permanent or semi-permanent data that is essential for booting and basic system operations.

MIMM is not a real type of computer memory module. DIMM (Dual Inline Memory Module), SIMM (Single Inline Memory Module), and RIMM (Rambus Inline Memory Module) are all actual memory module types used in computers. MIMM appears to be a made-up term.

Six disks cost $8.00, so each disk costs $8 ÷ 6 = $1.33. With $40, you can buy $40 ÷ $1.33 = 30 disks exactly. Option B (30) is correct because 30 × $1.33 = $40.

MOM is a common corporate abbreviation used in emails and official communications to refer to the written record of discussions and decisions made during a meeting. The other options - Master object memory, Master-plan orientation memo, and Mother of methods - are not standard abbreviations used in business contexts.

Intel (founded by Robert Noyce and Gordon Moore) pioneered RAM chip development with the 1103 in 1970, the first commercially available DRAM. Intel's early innovations established them as a leader in semiconductor memory technology.

T-RAM stands for Thyristor Random Access Memory, a type of memory technology that uses thyristor devices as storage elements. Thyristors are semiconductor devices that can act as bistable switches, making them suitable for memory applications. Triode and Transistor RAM are different memory types, and 'Tri polar Range Acceleration Magnet' is not a real technology term.

TTRAM (Twin Transistor Random Access Memory) is a novel memory technology that uses two transistors per memory cell instead of the traditional one-transistor-one-capacitor (1T1C) DRAM design. The twin-transistor configuration improves data retention and reduces leakage current. Options A and D incorrectly use 'triode' (a vacuum tube term), while C says 'Triple' instead of 'Twin'.

Z-RAM (Zero Capacitor Random Access Memory) is a type of DRAM that uses the floating body effect of a transistor to store charge instead of a capacitor. Unlike options A and B that incorrectly suggest Z stands for 'zenith' or 'zinc', the Z specifically means 'zero' capacitor. Option C is incorrect because it misspells 'Access' as 'Access Memory'.

ROM (Read-Only Memory) is a type of computer memory that stores permanent instructions. As the name implies, the computer can read data from ROM but cannot write to or modify it, unlike RAM which is read-write.

RAM stands for Random Access Memory, a type of computer memory that allows data to be read and written in any order. 'Random access' means the computer can access any memory location directly without going through previous locations sequentially.

A register is a small, high-speed storage location directly within the CPU used to hold data, instructions, or memory addresses during processing. Registers can be general-purpose (used for various operations) or dedicated (special functions like program counter or stack pointer). Options A and C describe physical paper media, and registers are part of primary memory, not auxiliary memory.

A file server is a computer in a network that stores and manages files, allowing other computers (clients) on the network to access, store, and share those files. It serves as the central repository for documents, applications, and other files that multiple users need to access. Clip art refers to graphics, motherboards are computer circuit boards, and peripherals are external devices like keyboards and printers. The file server's specific role is centralized file storage and sharing across a network.
