Some distinct features of embedded computers are: 1. Embedded as a chip inside another device 2. Have all computers of a computer such as memory, CPU, Input, Output, etc. 3. Functionality is programmed into the hardware chip. 4. Can specifically do designated limited functions. 4. Enlist some distinct features of microcomputers. Ans. Some distinct features of microcomputers are : 1. Single chip processor 2. Can support a single-user at a time. 3. Generally operate on electricity. 4. Small size and low cost. 5. Low computing power. 6. Commonly used for personal applications. 5. Enlist some distinct features of supercomputers. Ans. Some features of supercomputers are : 1. Multiple CPUs and GPUs. 2. Fastest of all types. 3. Very large scale computing power. 4. Used mainly for large scale huge data, research and scientific and engineering applications. 6. How are low-level languages different from high level languages?

2 Ans. LOW LEVEL LANGUAGES HIGH LEVEL LANGUAGES 1. It uses binary language i.e. in the form of 0 and It uses English like words. 2. It is difficult to learn. 2. It is easy to learn. 3. Near to computer. 3. Near to humans. 4. Codes can directly run on hardware i.e. no conversion required. 5. Machine language and assembly language are some examples of low level languages. 4. Cannot run directly on hardware i.e. translator is required. 6. C, C++, Java, PHP, COBOL are some examples of high level languages. 7. Name some low-level languages. Ans. Machine language and Assembly language are some low- level languages. 8. Name some high- level languages. Ans. C, C++, Java, PHP, COBOL are some examples of high level languages. 9. Name some language translators. Ans. Some language translators are compiler, interpreter and assembler. 10. What is a mainframe computer? Ans. It is a high performance computer used for large scale computing purposes such as census, consumer statistics, etc. It has large number of CPUs, huge memory capacity, enhanced software support and much more. It can manage large number of users. 11. What is an interpreter? Ans. Interpreter is a language translator which converts program code into machine code line by line. It will first convert the first code line run it, then move to second line. 12. Compare compiler and interpreter. Ans. COMPILER INTERPRETER 1. Converts entire program in one go. 1. Converts single instruction at a time. 2. Error list is generated with line numbers after full program is checked. 2. Errors are generated for one instruction at a time. 3. After compilation, full program runs. 3. Code runs line by line. 4. Compiler no longer need after compilation is done. 4. Interpreter is always needed. C. Identify the following: 1. I am a computer and can support multiple users and multiple processes, but I am smaller and slower than a mainframe computer. Mini Computers 2. I am very expensive, very powerful as I contain multiple CPUs and GPUs. I am used for complex scientific research. Weather forecasting, engineering research etc. Supercomputer 3. I contain a single chip CPU and am used in most homes and basic offices tasks. Microcomputers 4. I am designed for gaming. My memory, CPU and power, support online and offline gaming. Game consoles 5. Though I do not exist separately as I exist within device but I automate many tasks and functions of that device. Embedded Computers 6. I am mainly used for Artificial Intelligence purposes. 5GLs 7. Programs written in me are very small as programmer needs not specify the procedure in detail; just WHAT is required is enough. 4GLs 8. I am easily understood by computer hardware as I talk in their language through 1 s and 0 s. Machine Language( 1GL) 9. I am also near to computer hardware but I use mnemonics to specify instructions. After little conversion, computer hardware can easily run my programs. - Assembly Language(2GL) 10. I am near to human programmers as I use English like words. Programs written in me need to be converted to machine language using a compiler or interpreter. High Level Languages ( 3GL)

3 A. Fill in the blanks: BEDI INTERNATIONAL SCHOOL, BAREILLY CLASS: VI SUBJECT: Computer CHAPTER: 2( File Management-Organization of Data) File is smallest unit of storage. A file extension depicts the type of data the file stores. File names contain extensions. Folder inside other folder is called sub-folder. A hard disk can have multiple drives in it. A drive is a whole or sub part of hard disk. The disk drive and storage devices have one letter names followed by colon(: ) When you have a window in maximized form, the maximize button changes to Restore button. Two special characters? and * are called wildcards. Maximize button enlarge a window to its largest possible size. B. Answer the following: 1. What is a file? Ans. A collection of data or information that has a name called the filename. Almost all information stored in a computer must be in a file. There are many different types of files data files, text files, program files and so on. 2. How is folder related to files? Ans. Folders helps you keep your files organized and separate. Folder can contain one or more files,file of any type. It also allow you to have more than one file with same file name. 3. What is the difference between a file and a folder? Ans. FILE FOLDER It is the smallest unit of storage. Each file has its own extension. You cannot create any folder or sub folder within a file. After creating files you can easily open, save, rename, print, and modify file contents. Files take space on computer memory. It is the bigger unit of storage. A folder does not have any extension. You can create different types of files and folders in a folder. After creating folders you can move, rename and delete folders. Folders do not take spaces on computer memory. 4. What is the difference between copying and moving files and folders? Ans. Copying files and folders means to create a duplicate copy of it at the new place at the same time keeping it at its old place. Moving files and folders means to transfer the file and folder from old place to new place i.e file and folder will only be at new place. 5. What is file format? Ans. A file format is a standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium 6. Give examples of some common file formats. Ans. Some common file formats are:

4 Image files -.bmp,.gif,.png, etc Multimedia files -.mp3,.mp4,.ogg,.wav, etc Word processor and other text files -.doc,.pdf,.txt, etc. Spreadsheet files -.xlsx,.ods,. clr, etc. Internet related files -.html,.css,.php,.asp,etc.
