COMPUTER PART V =========================================== 401) In computer parlor a mouse is a screen saver 402) UNIVA is the name of the computer which was first used for programming and playing of music 403) The IC chips for computer is prepared from silicon 404) Database management systems are comprised of tables that made up of rows called records and columns called fields 405) Nano is equal to 10(to the power of -9) 406) In computers RAM is a non-volatile memory 407) Disk and tape drives are commonly used as hard copy 408) When computer is connected to LAN and data is sent across it for storage/processing is online processing 409) The primary storage unit is also referred to as internal storage 410) Oracle is not an operating system 411) Data are raw facts and figures 412) Holding of all data and instructions to be processed is one of the functions of storage unit 413) To select the entire row in Excel, click mouse at row heading 414) Database is known as structured data 415) Normal view and outline view notes pane appears in power point 416) The user protection feature of an operating system is required in multi-user system only 417) In word, Ctrl + Del combination of keys press to delete an entire word 418) In MS-Word double clicking a word selects the word 419) Word document can be navigated in web layout view 420) In Excel, addressing mode(s) that can be used in a formula is/are only absolute and relative 421) Note page views can you use to show just the slide and its contents 422) Hardware that adds two numbers is arithmetic logical unit 423) The computer as a machine and all other physical equipment associated with it are termed as hardware 424) Plotters are very useful in applications such as computer aided design 425) Corel DRAW is a graphic package 426) The print to file option creates .prn file 427) The enhanced keyboard contains 101 keys 428) Data processing cycle consists of input cycle, output cycle and processing cycle 429) Page Setup is not an option of Edit menu 430) Radar chart is used to show a correlation between two data series 431) A computerized business information system includes hardware, software and data facts 432) Purchase order file is a transaction file 433) A typical computerized business application system will have both master and transaction file 434) Problem identification is taken first in designing a program 435) The purpose of the EXIT command is to get out of a condition loop 436) Employees details is a master file for the pay roll system 437) A slow memory can be connected to 8085 by using READY 438) A processor needs software interrupt to obtain system services which need execution of privileged instructions 439) A CPU has two modes- privileged and non-privileged. In order to change the mode from the privileged to the non-privileged, a software interrupt is needed 440) Swap space resides at disk 441) The process of assigning load addressed to the various parts of the program and adjusting the code and data in the program to reflect the assigned address is called relocation 442)1 Sector= 4096 bytes 443) Two stacks of size required to implement a queue of size n 444) 1 Floppy = 6, 30,784 bytes or 308 KB 445) Consider a machine with 64 MB physical memory and a 32-bit virtual address space. If the page size is 4 KB, then size of the page table is 2 MB 446) Consider a virtual memory system with FIFO page replacement policy. For an arbitrary page access pattern, increasing the number of page frames in main memory will always decrease the number of page faults 447) Consider a scheme R(A, B, C, D) and functional dependencies A->B and C-> D. Then the decomposition of R into R1 (AB) and R2 (CD) is dependency preserving and lossless join 448) Main memory requires a device driver 449) RAM can be divided into 2 types 450) Two friends suitably arrange 4 blocks of different colors to exchange coded information between them. 4 bits of information is one exchanging each time 451) Cache memory is a part of main memory 452) The number 43 in 2’s complement representation is 01010101 453) The 8085 microprocessor responds to the presence of an interrupt by checking the TRAP pin for ‘high’ status at the end of each instruction fetch 454) All machinery and apparatus of computer is called hardware 455) The number 1024 bytes is the complement representation of 1 Kilo byte 456) System design specifications do not include blueprint showing the layout of hardware 457) Web pages are uniquely identified using URL 458) The results of arithmetic and logical operations are stored in an accumulator 459) The input device that is closely related to touch screen is the light pen 500) F2 keys of control center specified below displays data, toggles browse/edit
