    Directions for Questions 11-15:

    Read the passage and answer the questions that follow on the basis of the information

    provided in the passage. Microprocessor is an electronic computer Central Processing Unit (CPU) made from miniaturized transistors and other circuit elements on a single semiconductor Integrated Circuit (IC). Before the advent of microprocessors, electronic CPUs were made from individual small-scale Integrated Circuits containing the equivalent of only a few transistors. By integrating the processor onto one or a very few large-scale Integrated Circuit packages (containing the equivalent of thousands or millions of discrete transistors), the cost of processor power was greatly reduced. The evolution of microprocessors has been known to follow Moore's Law when it comes to steadily increasing performance over the years. This law suggests that the complexity of an Integrated Circuit with respect to minimum component cost will double in about 18 months. From humble beginnings as the drivers for calculators, the continued increase in power has led to the dominance of microprocessors over every other form of computer; every system from the largest mainframes to the smallest handheld computers now uses a microprocessor at their core. .As with many advances in technology, the microprocessor was an idea wbose time had come. Three projects arguably delivered a complete microprocessor at about the same time: Intel's 4004, Texas Instruments' TMS1000, and Garrett AiResearch's Central Air Data Computer. . A computer-on-a-chip is a variation of a microprocessor, which combines the microprocessor core (CPU), some memory, and I/O (input/output) lines, all on one chip. The proper meaning of microcomputer is a computer using a (number of) microprocessor(s) as its CPU(s), while the concept of the patent is somewhat more similar to a micro controller.


    11) Which of the following descriptions would NOT fit a microprocessor?

    A) Electronic computer

    B) Central Processing Unit

    C) Memory disk

    D) A single integrated chip circuit.


    12) Select the TRUE statement from the following.

    A) Microprocessors and computers on a chip are variations of each other.

    B) Integration of processing power on chips has made processing power cheaper.

    C) Before microprocessors, CPUs were not made from individual small scale ICs.

    D) A microprocessor circuit only has transistors in it.


    13) Which of the following was NOT the first to develop a microprocessor?

    A) Microsoft

    B) Intel

    C) Texas Instruments

    D) Garret


    14) According to the passage, which of these is NOT a use of microprocessors?

    A) Drivers for calculators

    B) Core for large mainframes

    C) Advanced mobile phones

    D) Used for small handheld computers


    15) "A number of microprocessors at its CPU" is an apt description of a:

    A) 11icro-controller

    B) Micro-computer

    C) Micro-processor

    D) Micro-transistor


    Directions for Questions 16-20:

    Read the passage and answer the questions that follow on the basis of the information provided in the passage.

    Dynamic Link Libraries Windows provides several files called dynamic link libraries (DLLs) that contain collections of software code that perform common functions such as opening or saving a file. When Windows application wants to use one of those functions or routines, the app sends a message to Windows with the names of the DLL file and the function. This procedure is known as calling a function. One of the most frequently used DLLs is Windows COMMDLG.DLL, which includes among others, the functions to display File Open, File Save, Search, and Print dialog boxes. The application also sends any information the DLL function will need to complete the operation. For example, a program calling the Open File function in COMMDLG.DLL would pass along a file spec, such as *. * or *.DOC, to be displayed in the dialog box's Filename text box. The application also passes along a specification for the type of information it expects the DLL to return to the

    application when the DLL's work is done. The application, for example, may expect return information in the form of integers, true/false values, or text. Windows passes the responsibility for program execution to the DLL, along with the parameters and the return information the DLL will need. The specific DLL is loaded into memory, and then executed by the processor. At this point the DLL, rather than the application, runs things. The DLL performs all the operations necessary to communicate with Windows and, through Windows, with the PC's hardware. After the DLL function is complete, the DLL puts the return information into memory, where it can be found by the application, and instructs Windows to remove the DLL routine from memory. The application inspects the return information, which usually tells whether the DLL function was able to execute correctly. If the operation was a success, the application continues from where it left off before issuing the function call. If the operation failed, the application displays an error message.

    16) By using DLLs, Windows:

    A) Saves processing time

    B) Multitasks

    C) Shares program code

    D) Communicates with PCs hardware


    17) To use any routine of a DLL, Windows:

    A) Searches and copies it in the application code and executes it

    B) Loads the DLL file and searches and executes the routine

    C) Loads just the required routine in memory and executes it

    D) Searches the location of the routine and instructs the application to execute it


    18) Which information does an application need to passto Windows to use a DLL routine?

    A) Just the name of the routine

    B) Just the name of the DLL, which finds in turn the routine to be executed in return

    C) Both the name of the routine as well as DLL and any parameters

    D) Name of the DLL, routine, any parameters and type of information to be returned



    19) According to the passage, while the DLL routine is executing, the calling application:

    A) Waits for the routine to execute

    B) Continues with other tasks

    C) Helps the DLL routine perform by communicating with Windows and through Windows with the PC's hardware

    D) Passes all responsibility of program execution to the DLL and is removed from memory


    20) The DLL function after execution returns:

    A) The parameters and information into memory, where it can be inspected by the calling application

    B) Information into memory, where it can be inspected by the calling application

    C) To the calling application the information required by it so that it can inspect it

    D) The information required into memory so that DLL can inspect whether the function operation was a success
