Freeware is software made available for public use by the author, and it's free. You're not under any obligation to pay for it. Freeware is usually distributed in the same places you find shareware and public domain software: on bulletin boards, at user groups, and by commercial shareware distributors.

The Desktop level is called a "level" because there is a hierarchy of different levels, kind of like different floors in a tall building. When you can actually see the Desktop, you can double-click to open folders and then you see that folder's window, right? That window is one level of the hierarchy. If you open another folder that is within that window, you go down one more level into the hierarchy. Well, the Desktop level is the very top of the hierarchy (or the root, some might say) because the first window (including the hard disk window) sits on the Desktop.

To understand what defragmentation IS, a person must first understand how data files are saved onto magnetic storage disks. Whether on a floppy disk or a hard disk, data is stored in a certain format. Formatting consists of dividing a disk into organized sections so that data can be located by the computer. Formatting organizes disks into concentric rings called tracks. Tracks are divided into sectors (pie shaped wedges) in which files and parts of files are stored.

Derived from Users Network this is, again, totally separate from the WWW. Briefly, the Internet is also home to what are called news groups which are broadly divided into several categories and which cater for every topic imaginable.

As all search engines are different they all operate in slightly different ways. The good news is that the same search techniques can be applied to them all, but, as might be expected, each one is a variation around the same theme. To make it even worse not all search engines actually search the Internet, some are what is known as web directories. Then, just to confuse the picture even more some engines do keyword searches while others are concept based.

The video card, as its name indicates is the component the computer whose role is to transmit data on the screen in the control of a microprocessor dedicated and integrated into the card. It is this microprocessor that calculates the position of points on the screen and processes the texture of restitution algorithms for display complex images such as those generated by video games.

HDMI. The High-Definition Multimedia Interface has been around since the early 2000s, and was developed for consumer electronics devices such as Blu-ray Disc players and HDTVs. However, HDMI has also seen wide use in graphics cards and computer displays. Its connector’s wide rectangle with two beveled corners can be adapted to DVI.

eSATA. The external SATA interface has been around longer than most of the ports we just described. Until USB 3.0 came along, this port was the fastest link to consumer storage peripherals such as external hard drives.

Essentially these are extra programs that can be installed and used as part of a Browser i.e. they plug into it. Typically these would provide extra facilities like the ability to handle sound files or advanced graphics. What this means in practice is that, should a web page incorporate sound as well as text, the relevant plug-in will be needed before it can be read by any Browser and the sound played through the computer's own speakers.

A Browser is a piece of software that everybody needs if they want to surf the Internet for useful or interesting websites. Web pages are designed to be read by Browsers and Browsers are designed to read web pages. Fortunately, acquiring a Browser is slightly easier than catching the common cold. They are everywhere. Most computers now come with one pre-installed. A great many CD-ROMs are now designed to be read like a website and so include a Browser which can be installed onto a computer's hard drive and ISPs give them away free to anyone who signs up for their service. There is nothing difficult about acquiring a Browser.

In American homes, or so the story goes, when visitors arrive they are given a cookie which in Britain would be a biscuit. This philosophy has now been extended to the Internet. Whenever a visitor, better known as a Browser, arrives at certain sites a cookie is sent down the line and saves itself to the local computer's hard disk.

Of all these error codes by far the most common is 404 which is also one of the few that can be worked around - always assuming the website has not simply ceased to exist. Everything else can be fixed although it would help to explain the difference between web names as they appear in the press and as they appear in a Browser.

Thunderbolt. The Thunderbolt standard (formerly called Light Peak) is aimed at being able to use a single interface for multiple device connections. Thunderbolt is a 10Gbps (1.25GBps) interface that combines PCI-E (Peripheral Component Interconnect Express) with DisplayPort in a single, thin cable. It can daisy-chain compatible devices, and it supports hubs, which lets you use a single cable connection to link your computer to a mouse, keyboard, monitor, and external storage drive. Even data from an external RAID (redundant array of independent drives) array of SSDs wouldn’t hit a bottleneck on its way to your computer, thanks to Thunderbolt.

DisplayPort is a super-fast, 21.6Gbps interface designed to carry video to computer monitors. With this much bandwidth on tap, it’s able to accommodate greater resolution, faster refresh rates, and more color depth than HDMI (High-Definition Multimedia Interface). Besides professional media content generation applications, DisplayPort (sometimes abbreviated DP) is ideal for multiple-monitor setups.

An embedded system is a complex system also known as an integrated system; It has software embedded into hardware (also known as Firmware) to perform specific tasks or a single task. It typically contains one or more microprocessors for executing a set of programs defined at design time and stored in memory. Which makes a system dedicated to a specific function, within a more extensive system. It is a low-power Microcontroller/Microprocessor based computer system, which dedicated to providing specific functionality.

• Switched-Mode Power Supply (SMPS) is an electronic circuit which converts the power using switching devices that are turned on and off at high frequencies, and storage components such as indicators or capacitors to supply power when the switching device is in its non-conduction state. It can be abbreviated as SMPS.
• The switched-mode power supply is also called switch-mode power supply or switching-mode power supply. Its efficiency is high. That’s why we use it in the variety of electronic types of equipment which require a stable and efficient power supply.
