### How many address lines are needed to address each memory location in a 2048 x 4 memory chip?

• A.

10

• B.

11

• C.

8

• D.

12

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.

### Who is credited with the idea of using punch cards to control patterns of a weaving machine?

• A.

Pascal

• B.

Hollerith

• C.

Babbage

• D.

Jacquard

D. Jacquard
Explanation

• A.

Duping

• B.

Booting

• C.

• D.

All of above

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".

### Plotter accuracy is measured in terms of repeatability and__________________.

• A.

Buffer size

• B.

Vertical dimensions

• C.

resolution

• D.

Intelligence

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.

### Daisy wheel printer is a type of

• A.

Matrix primer

• B.

Impact printer

• C.

Laser printer

• D.

Manual printer

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.

### Serial access memories are useful in applications where

• A.

Data consists of numbers

• B.

Short access time is required

• C.

Each stored word is processed differently

• D.

Data naturally needs to flow in and out

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.

### Which of the following memories must be refreshed many times per second?

• A.

Static RAM

• B.

Dynamic RAM

• C.

EPROM

• D.

ROM

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

• A.

Page Orientation

• B.

Paper Size

• C.

Page Layout

• D.
