INFORMATİON TECHNOLOGİES

The correct hierarchy as the building blocks of information science is Data - Information - Knowledge - Wisdom. Thus, the correct answer is A.

Wisdom refers to the ability to see the long-term consequences of any act and to evaluate them relative to the ideal of total control. Thus, the correct answer is D.

In computer systems, all arithmetic operations are performed in binary. Thus, the correct answer is E.

1 Kilobyte (KB) = 1.024 bytes
• 1 Megabyte (MB) = 1.024 KB = 1.048.576 bytes
• 1 Gigabyte (GB) = 1.024 MB = 1.073.741.824 bytes
• 1 Terabyte (TB) = 1.024 GB = 1.099.511.627.776 bytes

Thus, the correct answer is A.

ASCII code is used to represent information such as character-based data. Thus, the correct answer is A.

The correct order of steps applied to convert raw data into useful information is as follows: Collect-organize-analyze-store-process-transmit-display. Thus, the correct answer is A.

The input elements used in a computer system include the followings:

Keyboard - Mouse - Scanner - Microphone - Digital camera - Optical character reader - Storage devices: CD /DVD USB flash drive

Thus, the correct answer is B.

The main benefits of e-business include the followings:
• Reducing operating costs of business and its
processes and avoiding consumption,
• Increasing market opportunity (Faster access
to the market and customer trends),
• Fast access to customers: enabling them to
access the information about products or
services they need at any time (7/24),
• Elimination of processing errors,
• Strengthening internal management,
• Supply chain management: Provide uninterrupted
(continuous) supply chain,
• Reduction of sales cycles,
• Increasing visibility,
• Communication improvements,
• Predicting the fall in the probable life curve
of product.

Thus, the correct answer is E.

The main challenges in e-business include the followings:
• Determining customer’s changing needs,
• Organizational structure,
• The high speed of the development of IT,
• Integration of the front and back-end systems
of the organization,
• A lack of qualified human resources,
• The complexity of ensuring security,

Thus, the correct answer is D.

Workstation is like a PC, but it has more resources in terms of processing
power and memory. Thus, the correct answer is E.

In general, computers can perform three basic operations. Firstly, they accept data (input) from users via various input devices. Secondly, they process the data. Finally, they store the processed data in a memory or transfer it to various output devices in the desired format (text, image, audio, video, etc.). "Heating" is not among the basic operations that computers can perform, so the answer is D.
