Quiz On Computer Components! MCQ

The correct answer is that the DVD ROM has much more storage capacity than the CD ROM. DVDs can typically store up to 4.7GB or 8.5GB of data, while CDs can only hold up to 700MB of data. This difference in storage capacity allows DVDs to store larger files, such as movies, software applications, and games, compared to CDs which are better suited for smaller files like audio tracks or documents.

A hard drive is a device used for storing data and documents. It is a non-volatile storage device that is commonly used in computers and laptops. It provides a large amount of storage space for files, software, and operating systems. Hard drives use magnetic storage to store and retrieve data quickly and efficiently. They are essential for storing and accessing files, documents, media, and other digital content on a computer system.

The correct answer is 1.44MB. Floppy disks were a popular storage medium in the past, and the most common size was the 1.44MB capacity. This means that the floppy disk could store approximately 1.44 megabytes of data. Other options given in the question, such as 858MB and 98MB, are not correct as they do not align with the standard capacity of a floppy disk. The option "Whatever size you want" is also incorrect as it implies that the capacity of a floppy disk can be customized, which is not the case.

The answer is "No, because they don't match" because LGA775 and LGA771 are different socket types and are not compatible with each other. The number in the socket type indicates the number of pins on the socket, and since LGA775 has a different pin configuration than LGA771, a motherboard with LGA775 socket cannot be used for a CPU with LGA771 socket.

1 gigahertz is equivalent to 1,000,000,000. This is because "giga" is a prefix that denotes a factor of 1 billion. Therefore, 1 gigahertz represents 1 billion cycles per second.

The purpose of the FAN in a CPU is to prevent the CPU from overheating. When the CPU is in use, it generates heat, and if this heat is not dissipated properly, it can damage the CPU. The FAN helps to circulate air around the CPU, removing the excess heat and maintaining a safe operating temperature. By preventing the CPU from overheating, the FAN ensures that the CPU does not blow or get damaged.

The latest hard drive in town is a terabyte. It is available at PC World for $900 or £750.

The speed measurement of a processor is typically measured in MHz (Megahertz). This unit represents one million cycles per second, indicating the number of instructions the processor can execute in a given time frame. GHz (Gigahertz) is also a valid speed measurement for processors, representing one billion cycles per second. However, in this case, MHz is the correct answer as it is the only option provided that accurately represents the speed measurement of a processor.

The correct answer is £111.92. This is the price of the Sapphire ATI Radeon HD 4850 512MB GDDR2 PCI-E Graphics Card.

The price for the PNY 1GB PC2-5300 DDR2 SODIMM Memory is £15.49.
