Computer General Knowledge Quiz Questions And Answers

Explanation
Tim Berners Lee is credited with coining the term "www" which stands for World Wide Web. He developed the concept of the World Wide Web in the late 1980s and early 1990s while working at CERN. The term "www" became widely used to refer to the system of interconnected hypertext documents accessible via the internet. Tim Berners Lee's contributions revolutionized the way information is shared and accessed, making the World Wide Web an integral part of modern society.

Explanation
Charles Ranlett Flint is the correct answer for the founder of IBM. Flint was an American industrialist and the founder of the Computing-Tabulating-Recording Company (CTR), which later became International Business Machines (IBM). He played a crucial role in merging several companies to form CTR and establishing it as a leading manufacturer of business machines. Flint's vision and leadership laid the foundation for the success and growth of IBM as a global technology company.

Explanation
SATA stands for Serial Advanced Technology Attachment. It is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives and solid-state drives. The other options, Swiss Automated Technology Attachment and Solo Advanced Techno Authority, are not recognized acronyms or explanations for SATA.

Explanation
DDR3 SDRAM stands for Double Data Rate 3 Synchronous Dynamic Random-Access Memory. The memory clock frequency of 100 MHz indicates that the data is transferred twice per clock cycle. Therefore, the effective transfer rate is calculated by multiplying the memory clock frequency by 2. So, 100 MHz x 2 = 200 million transfers per second. Since DDR3 SDRAM transfers 8 bytes of data per transfer, the maximum transfer rate is 200 million transfers per second x 8 bytes = 1600 million bytes per second. Converting this to megabytes, we get 1600 million bytes per second / 1000 = 1600 MB/s. However, DDR3 SDRAM is capable of dual-channel operation, which doubles the transfer rate. Therefore, the maximum transfer rate is 1600 MB/s x 2 = 3200 MB/s.

Explanation
Vladimir Levin is the correct answer because he is known for being a black cat hacker who stole $10,000,000 from Citigroup. He gained unauthorized access to the bank's computers and transferred the funds to various accounts around the world. Levin was eventually caught and sentenced to prison for his cybercrime.

Explanation
Small Web Format (SWF) is a file format used for multimedia, vector graphics, and ActionScript in Adobe Flash. It was originally developed by Macromedia and is now owned by Adobe. SWF files are commonly associated with ShockWave, a popular multimedia platform. Therefore, it is correct to refer to SWF as ShockWave Format.

Explanation
W3C stands for World Wide Web Consortium. The W3C is an international community that develops standards and guidelines for the World Wide Web. They work to ensure the long-term growth and accessibility of the web, promoting interoperability and encouraging the development of open standards. The W3C plays a crucial role in shaping the future of the web by providing technical specifications and guidelines for web technologies.

Explanation
Hardware refers to the physical components of a computer system that can be physically touched. This includes devices such as the monitor, keyboard, mouse, CPU, and memory. Unlike software, which refers to the programs and instructions that run on the computer, hardware is tangible and can be physically interacted with. Similarly, an operating system and data are not physical components of a computer system, so they cannot be physically touched.

Explanation
IC chips used in computers are usually made up of silicon. Silicon is a widely used semiconductor material due to its ability to conduct electricity under certain conditions. It is the main component in the manufacturing of integrated circuits, which are the building blocks of computer chips. Silicon's unique properties, such as its high melting point and ability to withstand high temperatures, make it an ideal material for creating reliable and efficient electronic devices.

Explanation
One Gigabyte is approximately equal to 1000,000,000 bytes. This is because the prefix "Giga" in the metric system represents a factor of 10^9, which means that one Gigabyte is equal to 1,000,000,000 bytes.
