  1.  DBRM takes care of storage of data in a database
  2.  A co-processor is used to improve the speed of mathematical calculations
  3.  Code segment register is where the microprocessor looks for instruction
  4.  The instruction of a program which is currently being executed is stored in main memory
  5.  In this processing, a number of jobs are put together and executed as a group batch processing
  6.  Mainly memories are divided into two types they are logical memories and physical memories
  7.  Negative numbers can be represented in signed binary form
  8.  The mouse interrupts usually occur if the system uses a mouse port
  9.  The ability to create new objects from existing objects is known as inheritance
  10.  File transfer is the function of the application layer
  11.  An E-R data model solves the problem of presenting huge information system data models is to users and developers
  12.  30 pin SIMM’s, 72 pin SIMM’s, 168 pins DIMM’s types of RAM sockets can be seen on motherboards
  13.  The most appropriate command to permanently remove all records from the current table is Zap
  14.  A two-way selection in C++ is the if…else
  15.  +12 V signal for disk drive is used for power supply
  16.  A technique for searching special databases, called data warehouses, looking for related information and patterns is called data mining
  17.  The scripts which are designed to receive value from Web users is CGI script
  18.  The inner core of an optical fiber is glass and plastic in composition
  19.  DIMM is not an I/O bus
  20.  Front end processor relieves the host computer from tedious jobs and does them itself
  21.  R-C coupling method is suitable for voltage amplification
  22.  A proxy server is used to process client request for web pages
  23.  E-R diagram represents relationship between entities of system
  24.  Array is linear data structure
  25.  First generation computers relied on machine language to perform operations, and they only solve one problem at a time
  26.  A small amount of memory included in the processor for high-speed access is called cache
  27.  A collection of related information sorted and dealt with as a unit is a file
  28.  The OSI model consists of seven layers
  29.  The “Nyquist theorem” specifies the minimum sampling rate to be twice the bandwidth of a signal
  30.  FDM technique transmits analog signals
  31.  FDDI access mechanism is similar to that of IEEE 802.5
  32.  Magnetic surface recording devices used in computers such as hard disks, floppy disks, CD-ROMs are called secondary / auxiliary storage devices
  33.  The sharing of a medium and its path by two or more devices is called multiplexing
  34.  In linked list, the successive elements must occupy contiguous space in memory
  35.  The maximum bandwidth of EISA bus is 33 M/sec
  36.  The Power on self-test(POST) determines the amount of memory present, the date/time, and which communications ports and display adapters are installed in a microcomputer
  37.  The extension of database file is given by db.
  38.  The sound signal carried by telephone line is analog
  39.  A computer system runs millions of cycles per second so that speed is measured in MHz
  40.  Gateway uses the greatest number of layers in the OSI model
  41.  Task pre-emption, task priority and semaphores are not needed by server program from an operation system
  42.  A compiler cannot detect logical errors in source programs
  43.  A virtual circuit is a physical connection between an endpoint and a switch or between two switches
  44.  In HTML coding, the following attributes color, size, face used in font tag
  45.  To identify particular location in storage area, we need an address
  46.  Dumb Terminals: Hardware configuration consisting of a keyboard and monitor that is capable of sending and receiving information but has no memory or processing capabilities.
  47.  BCD means binary coded decimal
  48.  The addressing modes that can be used in a formula is/are- absolute, relative and mixed
  49.  Manchester encoding is used in Ethernet technology
  50.  In spite of the extra power needed for refreshing. DRAMs are widely used in computers because of its lower cost relatives to SRAMs
Always bear in mind that your own resolution to succeed is more important than any other. - Abraham Lincoln
