Computer Memory and Storage Questions
B
Correct answer
Explanation
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.
B
Correct answer
Explanation
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.
-
Master object memory
-
Master-plan orientation memo
-
Mother of methods
-
Minutes of meeting
D
Correct answer
Explanation
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.
-
Kanar-do-Ne
-
Intel groups
-
Apple
-
Matoss
B
Correct answer
Explanation
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.
-
Triode Random Access Memory
-
Thyristor Random Access Memory
-
Transistor Random Access Memory
-
Tri polar Range Acceleration Magnet
B
Correct answer
Explanation
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.
-
Twin Triode Random Access Memory
-
Twin Transistor Random Access Memory
-
Triple Transistor Random Access Memory
-
Triple Triode Random Access Memory
B
Correct answer
Explanation
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'.
-
zenith Random Access Memory
-
zinc capacitor Random Access Memory
-
zinc capacitor Randomly Access Memory
-
zero capacitor Random Access Memory
D
Correct answer
Explanation
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
-
RAM
-
KRAM
-
none of the above
A
Correct answer
Explanation
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.
-
random only memory
-
read only memory
-
random access memory
-
reverse bias amp motor
C
Correct answer
Explanation
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.
-
Set of paper tapes and cards put in a file
-
Temporary storage unit within the CPU having dedicated or general purpose use
-
Set of capacitors used to register input instructions in a digital computer
-
Part of the auxiliary memory
B
Correct answer
Explanation
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.
-
Clip Art
-
Mother Board
-
Peripheral
-
File Server
D
Correct answer
Explanation
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.
-
FastEthernet Measuring Device
-
Flashing Media Diode
-
Fluorescent Multi-Layer Disc
-
Flash Media Drive
C
Correct answer
Explanation
FMD stands for Fluorescent Multi-Layer Disc, an optical disc technology that uses multiple fluorescent layers to store data, allowing much higher storage capacity than traditional DVDs or CDs. Each layer can be read independently without interference from other layers, enabling terabytes of storage on a single disc. The options FastEthernet Measuring Device, Flashing Media Diode, and Flash Media Drive are incorrect expansions.
-
Magnetic tape, Magnetic disk, Main memory, Cache, Registers
-
Registers, Cache, Main memory, Magnetic disk, Magnetic tape.
-
Registers, Main memory, Cache, Magnetic disk, Magnetic tape
-
Magnetic tape, Main memory, Magnetic tape, Cache, Registers
B
Correct answer
Explanation
Computer memory hierarchy by speed (fastest to slowest): Registers → Cache → Main memory → Magnetic disk → Magnetic tape. Access latency increases in this order. Registers are fastest (nanoseconds), while magnetic tape is slowest (minutes to hours).
-
2.0 GB
-
2.7 GB
-
1 GB
-
1.5 GB
B
Correct answer
Explanation
Gmail started with 1 GB of storage in 2004, which was revolutionary at the time. Google gradually increased storage over the years - first to 2 GB, then beyond. The 2.7 GB figure represents a specific point in Gmail's storage evolution timeline as the company continuously expanded storage capacity.
-
Dual Data Rate Segmented Dynamic Random Access Memory
-
Dual Data Rate Synchronus Dynamic Random Access Memory
-
Double Data Rate Synchronus Dynamic Random Access Memory
-
Double Data Rate Systematic Dynamic Random Access Memory
C
Correct answer
Explanation
DDR SDRAM stands for Double Data Rate Synchronous Dynamic Random Access Memory. DDR means it transfers data on both the rising and falling edges of the clock signal, effectively doubling the data transfer rate compared to single data rate memory.
