Exam 3: Computer Hardware

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

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

Data are processed and stored in a computer system through the presence or absence of electronic or magnetic signals to the computer. This is called a "binary" representation of data, because the computer and the media can exhibit only _______________ states or conditions.

When using _______________ speech recognition, software recognizes continuous, conversationally paced speech.

The function of an input device is:

A special type of parallel computing that relies on complete computers connected to a network by a conventional network interface is called _______________.

Which of the following is not a valid storage medium?

There are two basic types of semiconductor memory: Read Only Memory (ROM) and _______________.

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

Advances in video monitor technology, such as active matrix and dual scan capabilities, have improved the color, but not the clarity, of LCD displays.

Which of the following would perform the required mathematical and logic operations of a central processing unit (CPU)?

RFID chips may be attached to objects, but cannot be injected into them because it interferes with radio signal transmission.

A _______________ server is a powerful microcomputer that is used to coordinate telecommunications and resource sharing in small local area networks (LANs) and Internet and intranet web sites.

Moore's Law states that the number of transistors on an integrated circuit will __________ every _______________.

All of the following relate to Peripherals except:

Pen-based computing technologies are being used in many hand-held computers and personal digital assistants.

OCR technology is used to read codes on merchandise tags, product labels, credit card receipts, and other documents.

Use of _______________ panel video monitors for desktop systems has become more common as their cost has become more affordable.

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.

Magnetic tape devices are frequently called direct access storage devices (DASDs), while magnetic disks are known as sequential access devices.
