Is Cyber Warfare a Serious Threat?


Twenty first century being the post-industrial knowledge era where information is greatly valued, begs the question: is our information in safe hands? Created in 1969, the Internet continues to rise in its popularity to an extent where its incumbency is almost a subject of dependence for prosaic lives. Huge organizations and even governments use the Internet as a means of communication. Henceforth, extremely confidential and high priority commands run through wires as binary making it extremely theft prone. Cyberspace is the place harboring various computer network communications and a virtual world synopsis where cyber-weapon as a development of the era plays a vital role in constituting a virtual war - the cyber-war. Nations and various organizations have hence been taking part in cyber warfare, developing their capabilities for both defensive and offensive purposes. Cyber warfare is greatly driven by motives classified into military, civil, political and research bills. The ways in which cyber warfare allows the attacker to fulfill its purpose is analogous to real life methods such as espionage, sabotage and propaganda. Cyber warfare continues to emerge as an extremely serious threat due to the recent cyber-attacks carried out by various nations across the globe; not only has the United Nations recognized cyber warfare to be a threat to world peace, but the technological products that surround us have also been deemed to be involved in it however despite it being argued that a cyber-war is very improbable coupled with the hype being largely made by tech firms in order for them to make huge profits.

VGA board

A VGA board is a video card for a computer that supports the VGA format. It processes the information sent to it and sends video signals to the monitor via a VGA connector. A VGA board processes the information it receives from a computer and sends it to the monitor in five separate signals. Three signals contain discrete information for the levels for red, green and blue, the primary video colors. Two more signals contain horizontal and vertical synchronization information. The color signals illuminate pixels on the monitor by mixing levels of the three to create any single color. The synchronization signals ensure the correct pixels get illuminated a the correct time. VGA offers the highest quality screen presentation of all analog formats.

What is a USB?

What is a USB?
Universal Serial Bus (USB) is a way to connect peripheral devices to computers. It replaces the functionality of serial and parallel ports, including keyboard and mouse ports. USB uses a bus topology, which means peripherals can be daisy-chained together or connected through hubs. Up to 127 devices may be connected together at one time, and devices may be connected and disconnected while the computer is in operation (hot-swapping). To use USB peripherals, your computer must have either built-in USB capability or a USB expansion card installed. Your computer's operating system must be able to support USB as well.

What is BIOS?

BIOS (basic input/output system) is the program a personal computer's microprocessor uses to get the computer system started after you turn it on. It also manages data flow between the computer's operating system and attached devices such as the hard disk, video adapter, keyboard, mouse, and printer .

BIOS is an integral part of your computer and comes with it when you bring it home. (In contrast, the operating system can either be pre-installed by the manufacturer or vendor or installed by the user.) BIOS is a program that is made accessible to the microprocessor on an erasable programmable read-only memory (EPROM) chip. When you turn on your computer, the microprocessor passes control to the BIOS program, which is always located at the same place on EPROM.

How to deactivate a facebook account permanently

If you deactivate your account, your timeline disappears from the Facebook service immediately. People on Facebook won't be able to search for you, though some info, like messages you sent, may still be visible to others. We also save your timeline information (ex: friends, photos, interests, etc.) in case you want to come back.

What is a Computer?

A computer is a general purpose device that can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.

Conventionally, a computer consists of at least one processing element and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.

World Wide Web

The World Wide Web (abbreviated as WWW or W3, commonly known as the Web), is a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia, and navigate between them via hyperlinks.
