Computer fundamental MCQ Questions and answers- Technical Aptitude

The microprocessor was designed by a team consisting of Italian engineer Federico Faggin, American engineers Marcian Hoff and Stanley Mazor, and Japanese engineer Masatoshi Shima.

In the IBM PC-AT, the words AT stand for Advance technology. The IBM Personal Computer AT, more commonly known as the IBM AT and also sometimes called the PC AT or PC/AT, was IBM's second-generation PC, designed around the 6 MHz Intel 80286 microprocessor and released in 1984 as System Unit 5170.

In the late 1960s, IBM introduced a new, smaller, round-hole, 96-column card format along with the IBM System/3 computer. These cards have tiny (1 mm), circular holes, smaller than those in paper tape. Data is stored in 6-bit BCD, with three rows of 32 characters each or 8-bit EBCDIC.

Each arc of this network is associated with a similarity measure between values of the nodes. This measure can be Pearson correlation, mutual information or others. The node values are vectors of real numbers. Learn more in: Methods for Reverse Engineering of Gene Regulatory Networks.

TRADIC, developed by Bell Labs in 1954, was the first fully transistorized computer in the world.

Before transistors, computers relied on vacuum tubes, which were large, consumed more power, and were less reliable.

TRADIC (Transistorized Airborne Digital Computer) replaced all vacuum tubes with transistors, making it more efficient and compact compared to its predecessors.

Other computers like the IBM-1401 and Datamatic-1000 came later and were among the early commercial machines to use transistors, but they were not the first.

Therefore, TRADIC holds the distinction of being the first computer to use transistors instead of vacuum tubes.

A CPU's processing power is measured in MIPS.
Million instructions per second (MIPS) is an approximate measure of a computer’s raw processing power. MIPS figures can be misleading because measurement techniques often differ, and different computers may require different sets of instructions to perform the same activity.

The binary equivalent of the Hexadecimal number 7BD is 11110111101. The binary equivalent of the Hexadecimal number 7BD is 11110111101. The hexadecimal system is commonly used by programmers to describe locations in memory because it can represent every byte.
7 = 111
B = 11 = 1011
D = 13 = 1101
= (11110111101)

Non-impact printers print the characters without using ribbons. These printers print a complete page at a time so they are also called page printers. E.g. Ink-Jet printer, Laser printer etc.

TIME's Machine of the Year. The cover of the January 3, 1983, issue of Time magazine features the headline, “Machine of the Year: The Computer Moves In.” In 1982, rather than naming a “Man of the Year,” Time magazine chose a “Machine of the Year.”

Intelligent Input/Output (I2O) was an input/output (I/O) specification that was designed to use an Intel i960 microprocessor as an I/O offloading engine. It was created by Intel Corporation in the mid-1990s to streamline and accelerate I/O operations on servers.
