Types of computer ports, connectors, and their symbols

First let’s try to answer the question, what is a computer port?

A computer port is a physical interface with the computer that is used to connect computer peripherals. 

To connect any external device to a computer you require to use a connector that goes to the port in the computer. Ports are used to connect peripheral devices to the computer motherboard or the casing.

The main ports that are in a modern computer are USB, HDMI, Ethernet, VGA, Power, Serial, PS/2, DVI, Audio, and Firewire among others. They are used to connect different devices to the computer for data transfer and communication. USB is replacing most of these other ports since is simple to connect and convenient.

Data security threats and control measures

Data and information are the key components in day to day running of any organization in today’s information age. Data security involves protecting data from theft, unauthorized access, and modification. Information is secured to achieve 3 main objectives namely confidentiality, integrity, and availability of data. The process involves securing all hardware, software, networking devices, and any other device involved in storing retrieval, and transmission of data.

Some of the main threats to data are malware, hackers, and employees’ natural catastrophe among others. To secure data organizations can implement control measures that can be used to mitigate the threats. Some of the data security control measures include using updated antivirus, encryption, firewalls, user access right, and user training among other controls discuss in the article.


Types of computer cooling systems and their functions 

A computer cooling systems are similar to a car engine system. A computer is an electronic device that performs millions of operations per second. This means the electronic components generate a lot of heat. Electronic components like transistors, diodes, and others require a certain temperature for optimum operation.

There are 2 main types of computer cooling systems, air, and liquid. The cooling system is used to ensure that the heat generated by computer components is removed and a cooler environment is maintained.

3D printer and products

Types of 3D printing process their advantages and disadvantages

3D printing is also known as additive manufacturing since it adds layers on top of others to create objects. Imagine you using utensils in your house and then they slip and break. Instead of going to the store for a new one you move to a printer and print a new better version.

This will be the future of 3D printing. 3D technology enables users to design an object by use of CAD software and then using a 3D printer they can generate the design into a physical object.

3D printing processes are, binder jetting, directed energy deposition, material extrusion, material jetting, powder bed fusion, sheet lamination, and vat photopolymerization. They will help have faster prototypes that can be customized to user needs. The disadvantage of 3D is it requires post-printing activities and currently is use limited types of material.

10 Application areas of virtual reality technology

Application areas and advantages of Virtual Reality Technology

Have you ever felt that you need to visit a fantasy place or even a real-life place but cannot? Virtual reality technology may be the future of achieving your dream or at least virtually.

Virtual reality (VR) is the use of computing technology to simulate a specific environment. It helps recreate a virtual environment that creates objects, events, and experiences to mimic the real world. Currently, users experience this by using a virtual reality headset.

Virtual reality is used in education, medical, entertainment, gaming, design, marketing, tour, and travel among other places. It offers users virtual experiences that they may not be able to get.


Types of computer keyboard keys and their functions

A computer keyboard is the main input device that almost all computers come with. It is used to enter instructions to the computer by pressing the keys which then send the command to the processor. They can be used in all kinds of devices that use different computer user interfaces from command, menu, and Graphic User Interface (GUI).

The main function of a keyboard is to key in data to the computer/device. It acts as a device input device for data entry. The main types of keyboard keys are functional, alphanumeric, formatting, special, and numeric among many others.

5G technology features, advantages, and disadvantages

What is 5G technology its features, pros, and cons?

The mobile device uses wireless technology to communicate from one point to another. 5G technology is the next promised land in terms of cellular communication from current 2G, 3G, or 4G technologies.

It is the latest technology and it has not been fully implemented. Some part of it is still in the development stages. 

The 5G technology is characterized by high-speed connectivity, low latency, security, and huge user capacity. It will offer a speed of upward of 10 Gbps and reduce the latency of data tremendously.

Advantages and disadvantages of the information age

The information age can also be referred to as the computer age, digital age, or data age.  The information age timeline can be dated from the 1940s when digital computers were first developed to solve human problems. It has moved the world from the industrial age to the current information age where “one who has information is the king”. 

The main characteristic of the information age is the digitalization of data, globalization, infobesity, and automation among others. The main benefit of the digital age is high data processing speed while the challenges are data privacy and over-dependence on technology.
