How many address lines are needed to address each memory location in a 2048 x 4 memory chip?
Correct Answer
B. 11
Explanation
To address each memory location in a 2048 x 4 memory chip, we need 11 address lines. This is because the memory chip has 2048 rows and 4 columns. To uniquely identify each memory location, we need to specify the row and column address. The number of address lines required is determined by the formula 2^n = total number of rows or columns. In this case, 2^11 = 2048, so 11 address lines are needed.

Which American Computer Company is called big blue?
.
Correct Answer
C. IBM
Explanation
IBM is called "big blue" because of its long-standing association with the color blue and its dominance in the computer industry. The nickname "big blue" originated in the 1960s when IBM introduced its mainframe computers, which were housed in large blue cabinets. Over the years, IBM has continued to use the color blue in its branding and marketing, solidifying the association between the company and the nickname. The term "big blue" has become synonymous with IBM and is widely recognized in the tech industry.

Correct Answer
C. USA
Explanation
The digital computer was primarily developed in the USA. This is because the USA was at the forefront of technological advancements during the mid-20th century, particularly in the field of computing. Companies like IBM and Bell Labs played a significant role in the development of early computers, such as ENIAC and UNIVAC. Additionally, universities like Harvard and MIT were conducting pioneering research in computer science. The USA's strong investment in research and development, along with its vibrant academic and industrial sectors, contributed to its leadership in computer technology during that time.

Correct Answer
B. Control and communications
Explanation
The subject of cybernetics deals with control and communications. Cybernetics is the study of systems that involve feedback and control mechanisms, such as machines, organisms, and social systems. It focuses on understanding how information is processed and communicated within these systems, and how they can be controlled and regulated. This field combines principles from various disciplines, including engineering, mathematics, biology, and computer science, to develop theories and models for understanding and designing complex systems.

Who is credited with the idea of using punch cards to control patterns of a weaving machine?
Correct Answer
D. Jacquard
Explanation
Jacquard is credited with the idea of using punch cards to control patterns of a weaving machine. Jacquard invented the Jacquard loom, which used punched cards to automate the weaving process. The punched cards controlled the pattern of the weave by determining which threads would be lifted or lowered during the weaving process. This innovation revolutionized the textile industry and laid the foundation for the development of early computer programming.
12.
Which of the following required large computer memory?
Correct Answer
D. All of above
Explanation
All of the options mentioned in the question, including Imaging, Graphics, and Voice, require large computer memory. This means that all of these tasks involve processing and storing large amounts of data, which necessitates a significant amount of memory. Therefore, the correct answer is "All of above."
13.
The processes of starting or restarting a computer system by loading instructions from a secondary storage device into the completer memory is called
Correct Answer
B. Booting
Explanation
Booting refers to the process of starting or restarting a computer system by loading instructions from a secondary storage device into the computer's memory. It is the initial set of operations that a computer system performs when it is powered on or reset. During the booting process, the computer's firmware or operating system is loaded, and various system checks and configurations are performed to prepare the computer for use. Therefore, the correct answer is "Booting".
14.
Plotter accuracy is measured in terms of repeatability and__________________.
Correct Answer
B. Vertical dimensions
Explanation
Plotter accuracy is measured in terms of repeatability and vertical dimensions. Repeatability refers to the ability of the plotter to produce consistent and precise results over multiple iterations. Vertical dimensions, on the other hand, refer to the accuracy of the plotter in accurately representing the height or depth of the plotted image. Both of these factors are crucial in determining the overall accuracy and precision of a plotter.
15.
Daisy wheel printer is a type of
Correct Answer
B. Impact printer
Explanation
A Daisy wheel printer is a type of impact printer. Impact printers work by striking a ribbon against the paper, creating an impression of the characters. Daisy wheel printers have a wheel-like device with characters on its spokes. When a character needs to be printed, the wheel rotates to position the desired character and then strikes the paper. This impact creates the printed character on the paper. Unlike laser printers, which use a laser beam to create an image, or manual printers, which require manual operation, daisy wheel printers rely on impact to produce printed output.
16.
Serial access memories are useful in applications where
Correct Answer
B. Short access time is required
Explanation
Serial access memories are useful in applications where short access time is required. This is because serial access memories allow for data to be accessed and read quickly, making them ideal for applications that require rapid retrieval of information. In contrast, random access memories may have longer access times due to the need to search and locate specific data within the memory. Therefore, in situations where quick access to data is crucial, serial access memories are the preferred choice.
17.
Which of the following memories must be refreshed many times per second?
Correct Answer
B. Dynamic RAM
Explanation
Dynamic RAM (DRAM) must be refreshed many times per second because it stores data in capacitors that leak charge over time. To prevent the loss of data, the memory cells in DRAM need to be refreshed periodically by reading and then rewriting the data. This process is necessary to maintain the integrity of the stored information and ensure that it is not lost. In contrast, static RAM (SRAM) does not require refreshing as it uses flip-flops to store data, which do not leak charge like capacitors. EPROM and ROM are non-volatile memories that do not require refreshing.

Portrait and Landscape are
Correct Answer
C. Page Layout
Explanation
The correct answer is "Page Layout" because both portrait and landscape orientations are options within the page layout settings. Page orientation refers to the direction in which the page is displayed (either vertically as portrait or horizontally as landscape), and this is determined within the page layout settings. Paper size is also a component of page layout, as it determines the dimensions of the page. Therefore, "Page Layout" encompasses all of the options mentioned in the question.
