<span class="Apple-style-span" style="font-size: 14px; line-height: 19px;"><span class="Apple-style-span" style="font-family: inherit;">The sole purpose of an Internet hard drive is to offer a means of accessing your computer files (pictures, documents, music, videos, etc.) from any computer, as long as that computer has access to the Internet. Similar to depositing money into your bank account, and later withdrawing that same money from any ATM machine, an Internet hard drive will allow you to "deposit" your computer files into a remote hard drive, and then later access those very same files from any other computer.</span></span><br />

<b>RAM</b><br />
<br />
<span class="Apple-style-span" style="font-family: sans-serif; font-size: small;"><span class="Apple-style-span" style="font-size: 13px; line-height: 19px;"><b><span class="Apple-style-span" style="font-weight: normal;"><b>Random-access memory</b> (<b>RAM</b>) is a form of computer data storage. Today, it takes the form of integrated circuits that allow stored data to be accessed in any order with a worst case performance of constant time. Strictly speaking, modern types of DRAM are therefore not random access, as data is read in bursts, although the name DRAM / RAM has stuck. However, many types of SRAM, ROM, OTP, and NOR flash are still random access even in a strict sense. RAM is often associated with volatile types of memory (such as DRAM memory modules), where its stored information is lost if the power is removed. Many other types of non-volatile memory are RAM as well, including most types of ROM and a type of flash memory called <i>NOR-Flash</i>. The first RAM modules to come into the market were created in 1951 and were sold until the late 1960s and early 1970s. However, other memory devices (magnetic tapes, disks) can access the storage data in a predetermined order, because mechanical designs only allow this.</span></b></span></span><br />

<b>ROM</b><br />
<br />
<span class="Apple-style-span" style="font-family: sans-serif; font-size: 13px; line-height: 19px;"><b>Read-only memory</b> (<b>ROM</b>) is a class of storage medium used in computers and other electronic devices. Data stored in ROM cannot be modified, or can be modified only slowly or with difficulty, so it is mainly used to distribute firmware (software that is very closely tied to specific hardware, and unlikely to need frequent updates).</span><br />

<b>High Definition Multimedia Interface</b><br />
<br />
<span class="Apple-style-span" style="font-family: sans-serif; font-size: 13px; line-height: 19px;"><b>HDMI</b> (<b>High-Definition Multimedia Interface</b>) is a compact audio/video interface for transmitting uncompressed digital data. It is a digital alternative to consumer analog standards, such as radio frequency (RF) coaxial cable, composite video,S-Video, SCART, component video, D-Terminal, or VGA. HDMI connects digital audio/video sources (such as set-top boxes, DVD players, HD DVD players, Blu-ray Disc players, AVCHD camcorders, personal computers (PCs), video game consoles such as the PlayStation 3 and Xbox 360, and AV receivers) to compatible digital audio devices, computer monitors, video projectors, and digital televisions.</span><br />

<br />
GUI is an Interface that allows users to interact with their machines or devices using graphics and images rather than text, which is called "command line" interface.<br />
Basically, on a GUI, everything is represented to make the system as user friendly as possible.<br />
For example, on windows, the graphical user interface utilizes icons and windows as their main <br />
user interface.<br />

<strong>Spreadsheet</strong><br />
<br />
A spreadsheet is a computer application that simulates a paper, accounting worksheet. It displays multiple cells usually in a two-dimensional matrix or grid consisting of rows and columns. Each cell contains alphanumeric text, numeric values or formulas. A formula defines how the content of that cell is to be calculated from the contents of any other cell (or combination of cells) each time any cell is updated. Spreadsheets are frequently used for financial information because of their ability to re-calculate the entire sheet automatically after a change to a single cell is made. A pseudo third dimension to the matrix is sometimes applied as another layer, or layers/sheets, of two-dimensional data.<br />

</tbody></table><strong>DBMS</strong><br />
<br />
A Database Management System (DBMS) is a set of computer programs that controls the creation, maintenance, and the use of a database. It allows organizations to place control of database development in the hands of database administrators (DBAs) and other specialists. A DBMS is a system software package that helps the use of integrated collection of data records and files known as databases. It allows different user application programs to easily access the same database.<br />
<br />
<strong>Utility Suites</strong><br />
<br />
A software suite or application suite is a collection of computer programs, usually application software and programming software of related functionality, often sharing a more-or-less common user interface and some ability to smoothly exchange data with each other.<br />
Sometimes software makers introduce "suites" that are little more than repackaged versions of older programs offered at a lower price. MS Office is one of the most well knowned utility suites.<br />

</tbody></table><strong>Bitmap Image</strong><br />
<br />
A bitmap or pixmap is a type of memory organization or image file format used to store digital images. The term bitmap comes from the computer programming terminology, meaning just a map of bits, a spatially mapped array of bits. Now, along with pixmap, it commonly refers to the similar concept of a spatially mapped array of pixels. Raster images in general may be referred to as bitmaps or pixmaps, whether synthetic or photographic, in files or memory.<br />
<br />
<strong>Desktop Publishing Program</strong><br />
<br />
Desktop publishing (also known as DTP) combines a personal computer and WYSIWYG page layout software to create publication documents on a computer for either large scale publishing or small scale local multifunction peripheral output and distribution. An example of a DTP software is Adobe FrameMaker.<br />
