Short Answer
1. Describe some types of utility programs. ____________ What is malware? ____________
Utility software is system software designed to help analyze, configure, optimize or maintain a computer.
Anti-virus utilities scan for computer viruses.
Archivers output a stream or a single file when provided with a directory or a set of files. Archive utilities, unlike archive suites, usually do not include compression or encryption capabilities. Some archive utilities may even have a separate un-archive utility for the reverse operation.
Backup software can make copies of all information stored on a disk and restore either the entire disk (e.g. in an event of disk failure) or selected files (e.g. in an event of accidental deletion).
Clipboard managers expand the clipboard functionality of an operating system .
Cryptographic utilities encrypt and decrypt streams and files.
Data compression utilities output a shorter stream or a smaller file when provided with a stream or file.

Malware is  software used to disrupt computer operation, gather sensitive information, or gain access to private computer systems. It can appear in the form of code, scripts, active content, and other software

2. What are the features of presentation software? ____________ What types of media might a person use to enhance a presentation? ____________
A presentation program is supposed to help both: the speaker with an easier access to his ideas and the participants with visual information which complements the talk. There are many different types of presentations including professional (work-related), education, entertainment, and for general communication. Presentation programs can either supplement or replace the use of older visualaid technology, such as Pamphlets, handouts, chalkboards, flip charts, posters, slides and overhead transparencies. Text, graphics, movies, and other objects are positioned on individual pages or "slides" or "foils". The "slide" analogy is a reference to the slide projector, a device that has become somewhat obsolete due to the use of presentation software. Slides can be printed, or (more usually) displayed on-screen and navigated through at the command of the presenter. Transitions between slides can be animated in a variety of ways, as can the emergence of elements on a slide itself. Typically a presentation has many constraints and the most important being the limited time to present consistent information.

Essentially, the most common ways to enhance a presentation involve effective use of Audio and Visual media. Since people receive information mostly through the eyes and secondarily through hearing, well-put audio-visual presentations are usually successful. You could use visual media, a chalkboard, an overhead projector, or video to enhance a presentation.

3. How is travel and mapping software used? ____________ What are some examples of reference software?____________
Users to view maps, determine route directions, and locate points of interest and also calculate mileage, time, and expense. 

Examples of reference software : dictionary, translation dictionary, encyclopedia, thesaurus, and atlas

4. What is computer-based training (CBT)? ____________ List a few examples of CBT usage. ____________
The use of information technology for any assessment-related activity. This definition embraces a wide range of student activity ranging from the use of a word processor to on-screen testing. Due to its obvious similarity to e-learning, the term e-assessment is becoming widely used as a generic term to describe the use of computers within the assessment process. Specific types of e-assessment include computerized adaptive testing and computerized classification testing.
E-assessment can be used to assess cognitive and practical abilities. Cognitive abilities are assessed using e-testing software, while practical abilities are assessed using e-portfolios or simulation software.
Example : Cambridge English COMPUTER-BASED exams

5. Describe how many Web sites utilize Web-based training. ____________ What are some ways that e-learning enhances communications? ____________
Web-based training (WBT) is a type of CBT (computer-based training) that uses Internet technology and consists of application software on the Web.

There are video conferencing, e-mail, blogs, wikis, newsgroups, chat rooms, and groupware

Assignment : Discovering Computer 2011 - Chapter 2 The Internet and World Wide Web

1. How Did the Internet Evolve? 
The history of the Internet began with the development of electronic computers in the 1950s. The public was first introduced to the concepts that would lead to the Internet when a message was sent over the ARPANet from computer science Professor Leonard Kleinrock's laboratory at University of California, Los Angeles (UCLA), after the second piece of network equipment was installed at Stanford Research Institute (SRI). Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, in which multiple separate networks could be joined together into a network of networks.
In 1982, the Internet protocol suite (TCP/IP) was standardized, and consequently, the concept of a world-wide network of interconnected TCP/IP networks, called the Internet, was introduced. Access to the ARPANET was expanded in 1981 when the National Science Foundation (NSF) developed the Computer Science Network (CSNET) and again in 1986 when NSFNET provided access to supercomputer sites in the United States from research and education organizations. Commercial Internet service providers (ISPs) began to emerge in the late 1980s and early 1990s. The ARPANET was decommissioned in 1990. The Internet was commercialized in 1995 when NSFNET was decommissioned, removing the last restrictions on the use of the Internet to carry commercial traffic.
Since the mid-1990s, the Internet has had a revolutionary impact on culture and commerce, including the rise of near-instant communication by electronic mail, instant messaging, Voice over Internet Protocol (VoIP) "phone calls", two-way interactive video calls, and the World Wide Web with its discussion forums, blogs, social networking, and online shopping sites. The research and education community continues to develop and use advanced networks such as NSF's very high speed Backbone Network Service (vBNS), Internet2, and National LambdaRail. Increasing amounts of data are transmitted at higher and higher speeds over fiber optic networks operating at 1-Gbit/s, 10-Gbit/s, or more. The Internet's takeover over the global communication landscape was almost instant in historical terms: it only communicated 1% of the information flowing through two-way telecommunications networks in the year 1993, already 51% by 2000, and more than 97% of the telecommunicated information by 2007.Today the Internet continues to grow, driven by ever greater amounts of online information, commerce, entertainment, and social networking.

2. What Are the Various Types of Internet Connections, and What Are the Differences between Broadband and Dial-Up Connections?  
Many home and small business users opt to connect to the Internet via high-speed broadband Internet connections. 
  • DSL (digital subscriber line) provides Internet connections using regular copper telephone lines. Cable Internet service provides high-speed Internet access through the cable television network via a cable modem. 
  • Fiber to the Premises (FTTP) uses fiber-optic cable to provide high-speed Internet access. 
  • Fixed wireless provides high-speed Internet connections using a dish-shaped antenna to communicate via radio signals. 
  • A cellular radio network offers high-speed Internet connections to devices with built-in compatible technology or computers with wireless modems. A Wi-Fi network uses radio signals. 
  • Satellite Internet service provides high-speed Internet connections via satellite. 
  • Some homes and small businesses connect to the Internet with dial-up access. Dial-up access, which is slower-speed technology, takes place when the modem in your computer connects to the Internet via a standard telephone line that transmits data and information using an analog (continuous wave) pattern.

3. What Are the Types of Internet Access Providers? 
An access provider is a business that provides access to the Internet free or for a fee. An ISP (Internet service provider) is a regional or national access provider. An online service provider (OSP) provides Internet access in addition to members-only features. A wireless Internet service provider provides wireless Internet access to desktop and notebook computers and mobile devices with built-in wireless capabilities (such as Wi-Fi) or to computers using wireless modems or wireless access devices.

4. What Is the Purpose of an IP Address, and What Is Its Relationship to a Domain Name? 
An IP address (Internet Protocol address) is a number that uniquely identify each computer or device connected to the Internet. The Internet relies on IP addresses to send data to computers at specific locations. The IP address usually consists of four groups of numbers, each separated by a period. A domain name is the text version of an IP address.
