Binary digits are almost always used as the basic unit of information storage and communication in digital computing and digital information theory.

More fundamentally, it turns out that it's easy to design and build electronic circuitry that is either in a fully on or fully off state, which leads naturally to a base 2 numbering system - 0's and 1's.

(aka web browser)

1. To be able to manage your online experience. For instance, knowing the difference between opening multiple instances of a browser or using tabbed browsing.
2. A browser is a primary mechanism for access to your PC by hackers, so it's good to know that you're using a browser and to take security measures accordingly.

The word "byte" has several closely-related meanings:

1. A contiguous sequence of a fixed number of bits (binary digits). In recent years, the use of a byte to mean 8 bits is nearly ubiquitous.

Specifically speaking, the best way to understand the potential speed of a CPU is to look at the results from a group of relevant (to your usage) benchmarks.

Although this idea is applied in a variety of ways, on many different kinds of applications, the easiest example to visualize is the current use of web pages on the internet. For example, if you are reading this article on Wikipedia, your computer and web browser would be considered a client, and the computers , databases, and applications that make up the Wikipedia would be considered the server. When your web browser requests a particular article from Wikipedia, the Wikipedia server finds all of the information required to display the article in the Wikipedia database, assembles it into a web page, and sends it back to your web browser for you to look at.

The key design goal of device drivers is abstraction. Every model of hardware (even within the same class of device) is different. Newer models also are released by manufacturers that provide more reliable or better performance and these newer models are often controlled differently.

Computers and their operating systems cannot be expected to know how to control every device, both now and in the future. To solve this problem, OSes essentially dictate how every type of device should be controlled. The function of the device driver is then to translate these OS mandated function calls into device specific calls.

An analogy would be if you only spoke English and wanted to talk to someone who spoke Spanish - you'd need a Spanish "driver" (interpreter). Or to talk to a teenager, you might need a TeenSpeak "driver" - ha ha.

HTTP is a request/response protocol between clients and servers. An HTTP client, such as a web browser, typically initiates a request...

Hyperlinks are part of the foundation of the World Wide Web created by Tim Berners-Lee.

There are a number of ways to format and present hyperlinks on a web page. An embedded link is one of the more common formats: one or more words of distinctively styled text. The ninth word of this sentence is an example of an embedded link.

Malware should not be confused with defective software, that is, software which has a legitimate purpose but contains errors or bugs.

In its most common usage, "memory" refers to very fast storage which does not retain its stored data when the power is turned off. Compare this to "storage", such as hard drive space, which is slow but keeps its data even without power. An analogy is to think of the storage as human memory, with the hard disk as long-term memory, and the memory as short-term memory.

When the meaning is spatial resolution, it refers to the amount of spatial detail in the image. The term is often used in relation to digital images, but is also used to describe how much detail can be recorded on photographic film on analog videotape, by an eye, etc. Higher resolution means more image detail, i.e. small details are apparent.

When the meaning is dynamic range, it refers to the amount of contrast available in each pixel. Dynamic range capability is limited by both capture and display capability in terms of the contrast range.

In color digital systems, the luminance and chrominance may be sampled at different intervals. Greater chroma subsampling gives rise to greater spatial resolution when color is a discriminator.

Spyware differs from viruses and worms in that it does not usually self-replicate. Like many recent viruses, however, spyware – by design – exploits infected computers for commercial gain.

Viruses are one of the several types of malicious software or malware. In a common parlance, the term virus is often extended to refer to worms, trojan horses and other sorts of malware; however, this can confuse computer users, since viruses in the narrow sense of the word are less common than they used to be, compared to other forms of malware. This confusion can have serious consequences, because it may lead to a focus on preventing one genre of malware over another, potentially leaving computers vulnerable to future damage. However, a basic rule is that computer viruses cannot directly damage hardware, but only software. An example of an indirect damage of the hardware is the overheating of the CPU, caused by an overclock or by stopping the cooling fans.
