These days our lives are run by technology, smartphones, tables, laptops and many others that we can’t seem to function and live without. Technology in a very short time has escalated the market and dominated it, in a short period of time it has become and essential tool in almost everything weathers its education, medication, planning, organization, and even communication, people nowadays can’t survive or imagine living without it. All technologies are born for a certain purpose, as the start we can say that there’s a mainly two types of these evolving technologies, and they are wired and wireless devices or networks that help us to communicate, or use that technology to the purpose it was made for.
Wired network, which as simply as it sounds, it refers to any medium that physically is consist of a cable. The cable can be twisted wire; which is a copper wire that is used for telephones and any data communication, and they are a pair of wires that are interweaved twisted together. Or a Coaxial Cable; that is also has copper wire, but surrounded by insulation and braided wire, such as television cables. Or Fiber optic cable; that is made from a strand that is thin which is made of plastic or glass, that get data threw as light pulses, such as Broadband. The main purpose of this cable is to transfer different types of electrical signals from one point to another, these connection is used in shared among two or more devices using a wired network concept.
On the other hand, we have wireless network, which as the name also represent a medium made of electromagnetic waves, or infrared waves. Most of the wireless devices either have an antenna or a sensor. Examples on wireless network is the use of; Radio transmission; which enables pictures, voice and music to travel threw air as a radio wave or frequency, this transmission only works in the 30 feet only. We also have microwave that transmit data in the form of electromagnetic radio waves in short frequencies; such as satellites. So the main different in wireless and wired communication; is that wireless network does not use cables of copper, or wires it uses radio frequency waves to connect one point to another.
The latest products that was born into our lives when it comes to wireless product are; Apple watches, Fit bit sugar, Google glass, Automated Door locks, security monitors, Wi-Fi printers, and Wifi routers, all these are the latest products of wireless technology that we use and surround us on a daily bases and became a key in our daily life. The latest products that was born into our lives when it comes to wired products are; routers, Televisions cable, subscriber loop carrier that link houses and business telephones, the local exchange switch, DSL modem. After reading about wired and wireless technology, its time that we discuss the fundamentals of privacy and security relation to the computer systems, and other networks.
Privacy is the ability to eliminate, and also restricts the use, and the giving of personal and confidential information, being able to protect what goes on and to stop what’s not needed to to shared, from private information. To keep yourself private can be done by using or creating the password system on your computer, or phone allowing yourself to protect your data from being view by someone snooping around looking to obtain information, or even harm you in anyway out there that could leave this data in the wrong hands, it could help if you have a strong password system that control the accessibility to the device that contain the information or even the account weather it’s a computer account or an internet one, the password should be a strong not predictable password with caps lock, numbers, and something that you wont forget, but also not something that is easy to be figures out , and also it helps to not leave your computer, or phone in a public place not attended meaning that many people might scroll into these information that’s on the device, or even steal the whole thing to not only obtain information and pictures on that device but also can get the contact information, credit card numbers, and also people that you know information, so leaving a device not attended is not a cleaver thing to do unless you are looking for trouble, as well as to stop Bluetooth, stopping Bluetooth will help with the stopping of received and transferring data into other devices, many hackers might send you a harmful virus using Bluetooth in the form of a picture, or even a music, or audio ware that will deceive you into opening it and all the data will be transferred into the person who has targeted you, so its advisable that you turn off the the Bluetooth when in not used and not to accept files from individuals you don’t know.
