Networks, Internet and Communications Quiz

Answer: MIT

A worm is a type of malicious software that self-replicates itself. The Morris worm was created by a Cornell University student named Robert Tappan Morris, but it was distributed through MIT to make it look as if it had originated there. This act also resulted in a felony conviction under the 1986 Computer Fraud and Abuse Act in the USA.

Answer: 4

The four computers to be connected were located at UCLA, Stanford Research Institute, UC Santa Barbara, and the University of Utah.

Answer: Atlantic Ocean

It was aptly called The Transatlantic Telegraph Cable. It revolutionized communication between continents, reducing the time to transmit messages from ten days to just 17 hours. It was an engineering marvel that connected Europe and North America with a long undersea wire, allowing electrical signals to be transmitted across the ocean floor.

Answer: Sputnik 1

The Soviet Union launched Sputnik 1 on October 4, 1957. It fueled the ongoing Cold War between the USA and the Soviet Union. In response, NASA launched Echo, Telstar, and Courier 1B in 1960. Sputnik 1 was the first artificial satellite to orbit Earth. One of its primary purposes was to collect valuable data on atmospheric conditions and radio signal propagation in space.

Answer: zoo

Jawed Karim, one of the co-founders of YouTube, filmed the first-ever YouTube video in San Diego Zoo in 2005. The 19-second video features Karim standing in front of elephants.

Answer: Cricket

Cricket is a sport that originated in England. It is played with a bat and a ball and bears some similarities to baseball. Snicko Meter, Hot Spot, and Hawk Eye are used for different purposes in cricket. Snicko Meter helps to determine if there was a slight contact between the bat and the ball. Hot Spot uses infrared technology to detect whether the ball has touched the pads or not. Finally, Hawk Eye uses multiple cameras to create a 3D path of the ball.

Answer: Wireless Andrew

Carnegie Mellon University, located in Pittsburgh, was one of the pioneers in establishing a campus-wide wireless connection known as Wireless Andrew in 1994. This wireless network was an important milestone in the field of wireless networking and was named after the two founders of Carnegie Mellon University - Andrew Carnegie and Andrew Mellon.

Answer: Multiplication of bandwidth and latency

Bandwidth indicates the number of bits that can be transmitted on a particular link in the unit of time. Latency or delay means the total time a packet (or datagram) takes to get transmitted from the source to the destination. Multiplication (product) of bandwidth and latency indicates the total number of bits that can be accommodated in a given volume of a link in the unit of time.

Answer: Presentation layer

RSA is an encryption algorithm, and encryption happens in the presentation layer. This algorithm was developed by Ron Rivest, Adi Shamir, and Leonard Adleman, so it is aptly named the Rivest-Shamir-Adleman (RSA) algorithm. The primary purpose of encryption algorithms is to hide or alter data such that it cannot be accessed or read by unauthorized individuals.

For example, ABC is encrypted to DEF by using an encryption key, and DEF is stored in the relevant computer systems. However, when the human user reads that data, it is decrypted back to ABC.

Answer: Interaction

The full form of HCI is Human Computer Interaction. HCI is about creating innovative technologies to facilitate interaction between humans and computers. If someone enters a room, and motion sensors activate the artificial light in that room, such a technology is called HCI.
