Correct Answer :   interface card

---

A Network Interface Card (NIC) is a device that allows computers to be joined together in a network, typically a Local Area Network (LAN). The network interface card acts as an interpreter, allowing the machine to both send and receive data on a LAN. Information Technology (IT) specialists often use these cards to setup wired or wireless networks.

Correct Answer :   Transistor technology

---

Transistor technology is the new buzzword in the computer world. Replacing silicon transistors with carbon nanotubes could make any electronic device — smartphones, laptops, tablets and supercomputers — smaller and more powerful using less energy than those built using silicon-based transistors. Scientists at Stanford University, in September 2013, announced to have built the first functioning computer that used only carbon nanotube transistors.

Correct Answer :   Weather Forecasting

---

A supercomputer is used for processing of information on quantum mechanics, large scale weather forecasting, molecular studies, polymer research, to solve mathematical problems, wind tunnel research, and chemical composition. Meteorologists use them to do research on the climate and global warming. It was first created in 1960.

Correct Answer :   Hierarchical database

---

A hierarchical database model is a data model in which the data is organized into a tree-like structure. The structure allows representing information using parent/child relationships : each parent can have many children, but each child has only one parent.

Correct Answer :   Clip Art

---

Clip art, in the graphic arts, refers to pre-made images used to illustrate any medium. Today, clip art is used extensively in both personal and commercial projects, ranging from home-printed greeting cards to commercial candles. Clip art comes in many forms, both electronic and printed. However, most clip art today is created, distributed, and used in an electronic form.

Correct Answer :   Valves

---

The Atanasoff–Berry Computer (ABC) was the world’s first electronic digital computer, albeit not programmable. Atanasoff is considered to be one of the fathers of the computer. In late 1939, John Atanasoff teamed up with Clifford Berry to build a prototype. They created the first computing machine to use electricity, vacuum tubes, binary numbers and capacitors. The capacitors were in a rotating drum that held the electrical charge for the memory. The final product was the size of a desk, weighed 700 pounds, had over 300 vacuum tubes, and contained a mile of wire.

Correct Answer :   TCP/IP Account

---

Computers connected directly to the internet are called “Servers,” while the computers we use are “clients,” because they are not connected directly to the internet, but through an Internet Service Provider. TCP/IP is the communication protocol for the internet. TCP/IP defines the rule computers must follow to communicate with each other over the internet.TCP provides a communication service at an intermediate level between an application program and the Internet Protocol (IP).

Correct Answer :   Stack

---

In computer science, LIFO refers to the way items stored in some types of data structures are processed. A LIFO structure can be illustrated with the example of a stack of trays. The term in computing generally refers to the abstract principles of list processing and temporary storage, particularly when there is a need to access the data in limited amounts, and in a certain order.

Correct Answer :   MHz

---

Speed of processor chip is measured in megahertz (MHz) and gigahertz (GHz).

Correct Answer :   Logical Errors
