Web-enabled personal digital assistants do indeed use touch screens, pen-based handwriting recognition, or keyboards to allow mobile workers to send and receive email, access the Web, and exchange information with their desktop PCs or Web servers.

Question 3

Network servers are some of the less powerful microcomputers; they are used to coordinate telecommunications and resource sharing in small LANs and in Internet and intranet websites.

Accepted Answer

Network servers are actually some of the more powerful microcomputers designed specifically for handling large amounts of network traffic and managing various resources such as files, printers, and applications.

Question 4

Midrange computers can act as powerful workstations for computer-aided design and other computation and graphics-intensive applications.

Accepted Answer

Midrange computers, also known as midrange systems, are designed to handle a wide range of computing tasks, including those that require significant processing power and memory. This makes them well-suited for applications such as computer-aided design (CAD), graphic design, and scientific simulations, where high-performance computing is essential. As such, midrange computers can function as powerful workstations for these types of applications.

Question 5

Midrange computers are often used as network servers in order to help manage large Internet websites,corporate intranets and extranets,and client/server networks.

Accepted Answer

Midrange computers are designed to handle more complex and demanding tasks, making them a suitable choice for network servers. They can handle large amounts of data and traffic, making them useful for managing large websites, corporate networks, and client/server applications.

Question 6

The first electronic digital computer was completed in the 1960s.

Accepted Answer

The first electronic digital computer was completed in 1942 during World War II, known as the Atanasoff-Berry Computer (ABC).

Question 7

All computers are systems of input,processing,output,storage,and distribution components.

Accepted Answer

The answer of All computers are systems of input,processing,output,storage,and distribution...

Question 8

Experts predict the merging or disappearance of several computer categories.For example,many midrange and mainframe systems have been made obsolete by the power and versatility of client/server networks composed of microcomputers and servers.

Accepted Answer

This statement is true, as many midrange and mainframe systems are now being replaced by client/server networks composed of microcomputers and servers due to their power and versatility.

Question 9

The computing power of microcomputers currently exceeds that of the mainframe computer of previous generations,at a fraction of the cost.

Accepted Answer

With advancements in technology, microcomputers such as laptops and smartphones now have a higher computing power than mainframe computers of the past, while costing significantly less.

Question 10

Today's corporate buyers seek PCs with network interface cards and/or wireless capabilities.

Accepted Answer

Today's corporate buyers look for PCs with network interface cards and wireless capabilities as they want to connect their computers to a network or the internet wirelessly for better productivity and convenience.

Question 11

The central processing unit (CPU)is the main processing component of a computer system.

Accepted Answer

The central processing unit (CPU) is indeed the main processing component of a computer system.

Question 12

Mainframe computers are sometimes used as front-end servers in order to assist midrange computers in performing telecommunications processing and network management.

Accepted Answer

Mainframe computers are typically used as back-end servers for large-scale processing and data management, while front-end servers are usually smaller systems that handle user interactions and network communications.

Question 13

Minicomputers are popular for process monitoring and instrumentation because these require very demanding processing versatility.

Accepted Answer

Minicomputers are not typically used for process monitoring and instrumentation; these tasks often require specialized systems like PLCs (Programmable Logic Controllers) that are designed for real-time processing and control, rather than the general-purpose computing versatility of minicomputers.

Question 14

The function of an input device is to interpret computer program instructions and to transmit directions to the other components of the computer system.

Accepted Answer

The function of an input device is to provide data or information to a computer system. It does not interpret computer program instructions - that is the function of the central processing unit (CPU). The CPU then transmits directions to the other components of the computer system.

Question 15

Personal computers,network servers,and technical workstations are terms used to highlight major uses of particular types of computers.

Accepted Answer

True, the terms mentioned are often used to categorize computers based on their primary uses.

Question 16

The term "megacomputer" describes a category of extremely powerful computer systems specifically designed for scientific,engineering,and business applications requiring extremely high speeds for massive numeric computations.

Accepted Answer

The term "supercomputer" is used to describe extremely powerful computer systems designed for high-speed numeric computations, not "megacomputer."

Question 17

Some microcomputers are powerful enough to support applications with heavy mathematical computing and graphics display demands,such as computer-aided design (CAD)or investment analysis.

Accepted Answer

Some microcomputers, especially those with high-end processors and graphics cards, can support high-demand applications such as CAD and investment analysis.

Question 18

The top criteria for corporate PC ownership are operating system ready,connectivity,solid performance,and global compatibility.

Accepted Answer

The answer of The top criteria for corporate PC ownership...

Question 19

Network servers are the most important category of computer systems for both businesspeople and individual consumers.

Accepted Answer

Network servers are crucial for managing network resources in businesses, but individual consumers often rely more on personal computers, smartphones, and tablets for their computing needs.

Question 20

Midrange systems first became popular as minicomputers for scientific research,instrumentation,engineering analysis,and process monitoring and control.

Accepted Answer

Midrange systems were initially used as minicomputers for various scientific and engineering purposes.
