Some programming-language features of Python are: A variety of basic data types are available: numbers (floating point, complex, and unlimited-length long integers), strings (both ASCII and Unicode), lists, and dictionaries. Python supports object-oriented programming with classes and multiple inheritances. GUI Programming − Python supports GUI applications that can be created and ported to many system calls, libraries and windows systems, such as Windows MFC, Macintosh, and the X Window system of Unix. Scalable − Python provides a better structure and support for large programs than shell scripting.

A reference identifies a cell or a range of cells on a worksheet and tells MS Excel where to look for value or data to be used in a formula. Using reference, we can use data present in different parts of a worksheet or on a different worksheet or another workbook. There are three types of references:

1. Relative Reference
2. Absolute Reference
3. Mixed Reference

In Microsoft Office PowerPoint 2007, different views of a slide are used to edit, print and deliver a presentation. PowerPoint slide views can be found in two places as follows:

1. On the View tab, in the Presentation Views group, where all views are available.
2. On an easy-accessible bar, at the bottom of the PowerPoint window, where the main views (Normal, Slide Sorter and Slide Show) are available. Different types of views available in PowerPoint 2007 are explained below:
   1. Normal View: This is the main editing view, where you write and design your presentations, i.e. actual screen which is displayed. The view is also known as Slide view. A Normal view is the default view size for the screen.
   2. Slide Sorter View: It provides a view of slides in thumbnail form. This view makes it easy to sort and organize the sequence of the slides at the time of creating presentation and also, at the time of preparing presentation for printing.
   3. Notes Page View: In the Notes Page view, the notes pane is located just below the slide pane. Here, notes that apply to the current slide can be typed. Later, these notes can be printed and referred while giving actual presentation. Notes can also be printed to handout to the audience or included in a presentation that is delivered to the audience or posted on a Web page.
   4. Slide Show View: This is used to deliver a presentation to the audience. Slide Show view takes up the full computer screen, like an actual presentation. In this view, you can see your presentation, the way audience wants. This view enables you to see how graphics, timings, movies, animated effects and transition effects will look during the actual presentation. To exit Slide Show view, press Esc key from the keyboard.
   5. Master View: The Master views include Slide view, Handout view and Notes view. They are the main slides that store information about the presentation, including background color, fonts effects, placeholder sizes and positions. The key benefit to working in a Master view is that on the Slide Master, Notes Master, or Handout Master, you can make universal style changes to every slide, notes page, or handout associated with the presentation.

Computer networks components comprise both physical parts as well as the software required for installing computer networks, both at organizations and at home. The hardware components are the server, client, peer, transmission medium, and connecting devices. The software components are operating system and protocols.

iOS

iOS is used on the iPad, iPhone, iPod Touch, iPod Nano, and Apple TV. There is an on going trend to merge iOS with Mac OS X. In the Apple store over a million Apps are available for the iPhone, and over five hundred thousand Apps are optimized for the iPad.

A word processor, or word processing program, does exactly what the name implies. It processes words. It also processes paragraphs, pages, and entire papers. Some examples of word processing programs include Microsoft Word, WordPerfect (Windows only), AppleWorks (Mac only),

Here the software designed to interact with major hardware is also called as driver marks.

It support to run major application over the device without meeting any virus affected problem and much more.

Hence the customer can feel free to install and make use computer with real fun for the client

True

Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations. The ALU is one component of the CPU(central processing unit). An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer.

Absolute An absolute cell reference is fixed. Absolute references do not change if you copy a formula from one cell to another. Absolute references have dollar sign ($) like $S$9. As the shows, when the formula =C4*$D$9 is copied from row, the absolute cell reference remains as $D$9

Information and Communications Technology (ICT) has an important role in the world since we are now in the information age era. With ICT, the company can make the business easier to happen with the client, supplier and the distributor. It is also very important in our daily lives. The lack of appropriate information at the right time will result in low productivity, low quality research works, and waste of time to pursue information and even to do research which actually others had done or in other countries. Nowadays ICT cannot be separated with our daily needs.

ICT has a great impact in our daily lives. For example, we can read our local newspaper using the online newspaper. Another example is we still can get connected with our family, relatives, or colleagues even if we are abroad by using the electronic mail, yahoo messenger, call conference, or video conference.

Digital computer and networking has changed our economy concept to the economy with no boundary in time and space because of ICT. It brings a lot of advantages for economic development enabling millions of transactions to happen in an easy and fast way.

ICT is one of the economic development pillars to gain national competitive advantage. It can improve the quality of human life because it can be used as a learning and education media, the mass communication media in promoting and campaigning practical and important issues, such as the health and social area. It provides wider knowledge and can help in gaining and accessing information.

ICT has become an integral part of everyday life for many people. It increases its importance in people’s lives and it is expected that this trend will continue, to the extent that ICT literacy will become a functional requirement for people’s work, social, and personal lives.

The use of ICT in education add value in teaching and learning, by enhancing the effectiveness of learning, or by adding a dimension to learning that was not previously available. ICT may also be a significant motivational factor in students’ learning, and can support students’ engagement with collaborative learning.

Mobile OS is the type of OS, that operates on Smartphones, Tablets, PDAs or other Digital Mobile devices. Several types of mobile operating systems are available in market as follows:
Android, BlackBerry, iOS, Windows etc.
Android is a Mobile OS which is based on Linux kernel and primarily designed for touch screen mobile devices.
It provides access to a wide range of useful libraries and tools that can be used to build rich applications. The latest version of Android operating system is Marshmallow 6.0.

Different types of RAM and ROM

Random Access Memory (RAM) is classified into two types. They are

• DRAM (Dynamic Random Access Memory) – DRAM Is commonly used as the main memory for the computer. Inside an integrated circuit, each DRAM memory cell consists of a transistor and a capacitor and a data bit is stored in the capacitor. Because transistors often leak a small amount, the condensers gradually discharge, allowing the information stored in it to drain thus, DRAM has to be refreshed every few milliseconds (given a new electronic charge) to maintain data.

• SRAM (Static Random Access Memory) – SRAM is composed of 4 to 6 transistors. It holds data in the memory as long as power is supplied to the device, unlike DRAM, which needs to be regularly refreshed. As such, SRAM is more costly but quicker, making DRAM the more widespread memory in computer systems.

Read-Only Memory has three types in it. They are

• PROM–PROM or programmable ROM is a computer memory chip that can be programmed once it is created. When the PROM is programmed, the written information is permanent and cannot be removed or erased.

• EPROM–Erasable Programmable Read-Only Memory, EPROM is a non-volatile memory chip, developed in 1971 by Dov Frohman. When exposed to ultraviolet light, an EPROM can be reprogrammed if necessary, but otherwise no new data would be accepted or saved. Computer manufacturers use EPROM when it might be necessary to modify the data stored on the EPROM. EPROM chips are not commonly used in computers and have been replaced by EEPROM chips.

• EEPROM–The EEPROM is an electrically erasable programmable read-only memory which can be erased and reprogrammed using an electrical charge. George Perlegos developed EEPROM while at Intel in 1978, and unlike most of the memory inside a computer, this memory remembers data when the power is switched off. EEPROM was a substitute for the PROM and EPROM chips and is used for the <a href="https://www.classmate4u.com/bios-basic-input-output-system/">BIOS </a>of later computers designed after 1994. Using an EEPROM machine helps a computer user to update the BIOS on their device without the need to open the computer or remove chips.
