Information Technology (IT) and Information and Communication Technology (ICT) are very often interchangeably used in the
context of modern technology infrastructure. ICT is a broad and comprehensive term, which comprises information technology and
communication technology. Information technology includes radio, television, computer and the Internet, teleconferencing, and mobile.
According to the American sociologist Earl Robert Babbie, “Research is a systematic inquiry to describe, explain, predict, and control the observed phenomenon. Research involves inductive and deductive methods.”
1. Over the past decade, there has been a significant increase in the scope of ICT to be employed in the fields of education and research.
2. Information and Communication Technology has done so much to remove from the researcher the constraints of speed, cost, and distance.
3. On the whole, information and communication technology has led to improvements in research.
4. New avenues for scientific exploration have opened. The amount of data that can be analyzed has been expanded, as has the complexity of analyses. And researchers can collaborate more widely and efficiently.
5. Though the use of ICT can be employed in every stage of the research process, the scope for employing ICT support is relatively more in the stages of Survey, Data Analysis, and Indexing The References.
6. Surveying the sample audience can be done through the use of ICT. Google forms, emails, social networking sites, etc. can be used to obtain information from our sample audience. Surveying through the help of ICT saves time, cost, and helps us reach a comparatively larger sample audience.
7. Analyzing data with computers is among the most widespread uses of information and communication technology in research.
8. Computer hardware for these purposes comes in all sizes, ranging from personal computers to microprocessors dedicated to specific instrumentational tasks, large mainframe computers serving a university campus or research facility, and supercomputers.
Computer software ranges from general-purpose programs that compute numeric functions or conduct statistical analysis to specialized applications of all sorts.
9. A citation index is an ordered list of cited articles along with a list of citing articles. The cited article is identified as the reference and the citing article as the source. The index is prepared to utilize the association of ideas existing between the cited and the citing articles, as the fact is that whenever a recent paper cites a previous paper there always exists a relation of ideas, between the two papers. Citation indexing provides subject access to bibliographic records in an indirect but powerful manner.
10. ICT helps to identify appropriate information sources so that their contribution can be acknowledged and plagiarism can be avoided.

Wireless networking is a method by which homes, telecommunications networks, and business installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. The main purpose of using a wireless network is its flexibility, roaming, low cost, and high standard.
Types of Wireless Networks.
- 1. WLAN (Wireless Local Area Network)
- 2. WWAN (Wireless Wide Area Network)
- 3. WMAN (Wireless Metropolitan Area Network)
- 4. WPAN (Wireless Personal Area Network)
- 5. Ad-hoc Network.
- 6. Hybrid Network.
Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smartphones and wearables), and other equipment (printers and video cameras) to interface with the Internet. Internet connectivity occurs through a wireless router.
• In general, wireless networks are less secure than wired networks since the communication signals are transmitted through the air. Because the connection travels via radio wave, it can easily be intercepted if the proper encryption technologies (WEP, WPA2) are not in place.
• Wired networks are generally much faster than wireless networks. This is mainly because a separate cable is used to connect each device to the network with each cable transmitting data at the same speed. A wired network is also faster since it never is weighed down by unexpected or unnecessary traffic.
• Wireless networks enable multiple devices to use the same internet connection remotely, as well as share files and other resources. There are also disadvantages to wireless networks, however, especially when you compare them with wired networks, which generally maintain a faster internet speed and are more secure.
Benefits of Wireless Network
• Increased Mobility: Wireless networks allow mobile users to access real-time information so they can roam around your company’s space without getting disconnected from the network. This increases teamwork and productivity company-wide that is not possible with traditional networks.
Installation Speed and Simplicity: Installing a wireless network system reduces cables, which are cumbersome to set up and can impose a safety risk, should employees trip on them. It can also be installed quickly and easily when compared to a traditional network.
• Wider Reach of the Network: The wireless network can be extended to places in your organization that are not accessible for wires and cables.
• More Flexibility: Should your network change in the future, you can easily update the wireless network to meet new configurations.
• Reduced Cost of Ownership over Time: Wireless networking may carry a slightly higher initial investment, but the overall expenses over time are lower. It also may have a longer lifecycle than a traditionally connected network.
• Increased Scalability: Wireless systems can be specifically configured to meet the needs of specific applications. These can be easily changed and scaled depending on your organization’s needs.

The origin of the term Algorithm is traced to Persian astronomer and mathematician, Abu Abdullah Muhammad ibn Musa Al-Khwarizmi (c. 850 AD) as the Latin translation of AlKhwarizmi was called ‘Algorithmi’.
• A programmer writes a program to instruct the computer to do certain tasks as desired.
• The computer then follows the steps written in the program code.
• Therefore, the programmer first prepares a roadmap of the program to be written, before actually writing the code.
• Without a roadmap, the programmer may not be able to clearly visualize the instructions to be written and may end up developing a program that may not work as expected.
• Such a roadmap is nothing but the algorithm which is the building block of a computer program.
• Hence, it is clear that we need to follow a sequence of steps to accomplish the task.
• Such a finite sequence of steps required to get the desired output is called an algorithm. It will lead to the desired result in a finite amount of time if followed correctly.
• The algorithm has a definite beginning and a definite end and consists of a finite number of steps.
• In mathematics and computer science, an algorithm is a finite sequence of well-defined, computer-implementable instructions, typically to solve a class of problems or to perform a computation or produce the desired output.
• Algorithms are always unambiguous and are used as specifications for performing calculations, data processing, automated reasoning, and other tasks.
• We can express an algorithm in many ways, including natural language, flow charts, pseudocode, and of course, actual programming languages.
• An algorithm expressed in a programming language is called a computer program.
• An algorithm is expressed in a graphical form known as a flowchart.
• For example, searching using a search engine, sending a message, finding a word in a document, booking a taxi through an app, performing online banking, playing computer games, all are based on algorithms.

1. A firewall is a system designed to prevent unauthorized access to or from a private network.
2. You can implement a firewall in either hardware or software form, or a combination of both.
3. Firewalls prevent unauthorized Internet users from accessing private networks connected to the internet, especially intranets.
4. All messages entering or leaving the intranet (the local network to which you are connected) must pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
5. In protecting private information, a firewall is considered the first line of defense; it cannot, however, be considered the only such line.
6. Firewalls are generally designed to protect network traffic and connections, and therefore do not attempt to authenticate individual users when determining who can access a particular computer or network.
• ROM stands for Read-Only Memory.
• ROM is a storage device that is used with computers and other electronic devices.
• Data stored in ROM may only be read.
• ROM is used for firmware updates, which means It contains the basic instructions for what needs to happen when a computer is powered on.
• Firmware is also known as BIOS, or basic input/output system.
• ROM is non-volatile storage, which means the information is maintained even if the component loses power.
• ROM is located on a BIOS chip which is plugged into the motherboard.
• ROM plays a critical part in booting up or starting up, your computer.
Random Access Memory (RAM)
• This memory allows writing as well as reading of data, unlike ROM which does not allow writing of data on to it.
It is volatile storage because the contents of RAM are lost when the power (computer) is turned off.
• If you want to store the data for later use, you have to transfer all the contents to a secondary storage device.
Dynamic random access memory (DRAM)
It is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function.
DRAM is a common type of random access memory (RAM) that is used in personal computers (PCs) workstations and servers.
Cache primarily refers to a thing that is hidden or stored somewhere, or to the place where it is hidden.
It has recently taken on another common meaning, “short-term computer memory where information is stored for easy retrieval.”
