Z-8000

B)

Z-8088

C)

Z-80

D)

Motorola 6809

Correct Answer : Option (C) - Z-80

Z-80 is a 8-bit chip was used in many of Tandy's TRS-80 computers

The TRS-80 Micro Computer System (TRS-80, later renamed the Model I to distinguish it from successors) is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy/Radio Shack, Z-80 microprocessor. It was one of the earliest mass-produced and mass-marketed retail personal computers.

The TRS-80 featured a full-stroke QWERTY keyboard, the new Zilog Z80 processor (rather than the more common Intel 8080), 4 KB DRAM standard memory (when many 8-bit computers shipped with only 1 KB RAM), small size and desk footprint, floating-point BASIC programming language, standard 64-character/line video monitor, and a starting price of US$600[1] (equivalent to US$2400 in 2017).

Correct Answer : Option (A) - IBM

IBM is the largest and most powerful computer manufacture in the world

IBM builds world's most powerful supercomputer to crack AI. An IBM-designed US supercomputer unveiled on Friday is set to leapfrog Chinese competition to become the world's most powerful for the first time in more than five years.

The US Again Has the World's Most Powerful Supercomputer. The IBM-built Summit supercomputer is the world's smartest and most powerful AI machine. Its racks are connected by over 185 miles of fiber-optic cables. the US Department of Energy and IBM unveiled Summit, America's latest supercomputer, which is expected to bring the title of the world's most powerful computer back to America from China, which currently holds the mantle with its Sunway TaihuLight supercomputer.

6 .

The accuracy of the floating point numbers representable in two 16 bit words of a computer is approximately

A)

4 digits

B)

6 digits

C)

16 digits

D)

None of the above

Correct Answer : Option (B) - 6 digits

The smallest change in a decimal number that can be portrayed by floating-point representation is called precision. The fractional part has exactly 24 bits of implied resolution. Accuracy, on the other hand, is the floating-point number represented by the number of prominent bits in which the range of after decimal is limited.

There are some standards to define very few special floating-point bit pattern zeroes which at the most can have only a single bit hence it can be normalized, the hidden but it is often represented by technique for storing zero.

7 .

The personnel which deal with the computer and its management put together is known as

A)

Software

B)

Hardware

C)

Firm ware

D)

Human ware

Correct Answer : Option (D) - Human ware

Humanware is hardware and software that emphasizes user capability and empowerment and the design of the user interface. The process of building humanware generally consists of these steps:

1. Define users (age, mindset, environmental context, previous product experience and expectations, and so forth) and what they really want to do.

2. Identify tasks they will need to do or capabilities they will want

3. Specify usability objectives (if possible, these should be measurable, such as how long to do something or how many mouse clicks to get to a specified task point) for each task or capability.

4. Build a prototype of the user interface (it can be a paper or simulated prototype if time is short)

5. Test and verify or correct the prototype

6. Provide the prototype and usability objectives to the program designers and coders.

The output quality of a printer is measured by

A)

Dots per inch

B)

Dots per line

C)

Dots printed per unit time

D)

None of the above

Correct Answer : Option (A) - Dots per inch

DPI is used to describe the resolution number of dots per inch in a digital print and the printing resolution of a hard copy print dot gain; the increase in the size of the halftone dots during printing. This is caused by the spreading of ink on the surface of the media.
