Give definition to E-learning

Understanding eLearning is simple. eLearning is learning utilizing electronic technologies to access educational curriculum outside of a traditional classroom. In most cases, it refers to a course, program or degree delivered completely online.

There are many terms used to describe learning that is delivered online, via the internet, ranging from Distance Education, to computerized electronic learning, online learning, internet learning and many others.

We define eLearning as courses that are specifically delivered via the internet to some where other than the classroom where the professor is teaching. It is not a course delivered via a DVD or CD-ROM, videotape or over a television channel. It is interactive in that you can also communicate with your teachers, professors or other students in your class. Sometimes it is delivered live, where you can “electronically” raise your hand and interact in real time and sometimes it is a lecture that has been prerecorded.

 

Describe a free software

Freeware is software that is free to use. Unlike commercial software, it does not require any payment or licensing fee. It is similar to shareware, but will not eventually ask you for payment to continue using the software. You can legally download and use freeware for as long as you want without having to pay for it.

Many types of software programs are offered as freeware, including games, utilities, and productivity applications. Since the software is free, you might wonder what incentive developers have to create freeware programs. Below are a few reasons a program might be offered as freeware:

To offer a program developed by a non-profit or educational institution to the public

To promote a brand or drive traffic to a company's website

To generate revenue through advertisements or in-app purchases within the program

To generate revenue by offering other programs during the installation process

To provide a "lite" version of a program that may lead users to upgrade to the full-featured version

While freeware is free to use, it is still copyrighted and may include a license agreement that restricts usage or distribution of the software. It is also not the same thing as open source software (or "free software"), which allows you to edit and redistribute the program's source code.

Give definition to Main terms of mobile technologies

In the computer world, the term mobile device refers to any electronic device that be easily moved from one location to another. Over time, this category has expanded to include cell phones, laptops, smartphones, smart watches, and other portable devices. The picture shows an example of one of the most common mobile devices today: the tablet computer.

Laptops became one of the first mobile computing devices by eliminating the wires between the computer and its peripherals; then integrating them into one unit. Today, mobile device usually refers to any hand-held computer capable of running applicationsthat can connect to the Internet wirelessly. However, even by today's more scrupulous standards, the category keeps expanding with new inventions. As is true in any branch of computing, our mobile devices continue to offer more advanced functions while reducing size and weight.

Mobile technology is the technology used for cellular communication. Mobile code division multiple access (CDMA) technology has evolved rapidly over the past few years. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, an embedded web browser and instant messaging client, and a handheld game console. Many experts argue that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by way of tablet computers are becoming more popular. Tablets are available on the 3G and 4G networks.

20. Give definition to Cybersecurity.

Computer security is the protection of computing systems and the data that they store or access.

Computer security, also known as cybersecurity or IT security, is the protection of computer systems from theft or damage to the hardware, softwareor the information on them, aswellasfrom disruption or misdirection of the services they provide.

Our daily life, economic vitality, and national security depend on a stable, safe, and resilient cyberspace.

Why do need to learn about Computer Security? Isn’t this just IT problem? Information is stored on computer hardware, manipulated by software, transmitted by communication, used by people, etc. each of these areas must be adequately protected!

“In the last 20 years, technology has permeated every facet of the business environment. The business place is no longer static – it moves whenever employees travel from office to office, from office to home, from city to city. Since business have become more fluid, …, information security is no longer the sole responsibility of a small dedicated group of professionals, …, it is now the responsibility of every employee, especially managers.”

Information security should balance protection & access - a completely secure information system would not allow anyone access, or would be very ‘user-unfriendly’!
