          A computer possesses information

          Pakexammcq Basic IT 0

          A. Automatically
          B. At Once
          C. By Truncating
          D. As directed by the operator




          Answer & Solution
          Option: A
          Explanation :A computer possesses information automatically. Computer is an electronic machine used to solve different problems according to a set of instructions given to it. A computer can accept data, process data into useful information and store it for later use.
          Computer can be used as calculating machine to produce results at very high speed but the calculation is not the only use of computer. People use computers to solve different problems quickly and easily. So computer has changed the way of life.
          A computer possesses information. The processed data is called information. In other words information is an organized and processed form of data. Information is more meaningful than data and it is used for making decisions. Further, Data is used as input for the processing and information is the output of this processing. The central processing unit CPU processes data into information.
          A series of steps used to convert data into useful information is called information processing cycle. Different steps in the information processing cycle are as follows:
          i. Input
          ii. Processing
          iii. Output
          iv. Storage

            A. Chip
            B. Memory
            C. Hard Disk
            D. Program




            Answer & Solution
            Option: D
            Explanation :A computer program is a collection of instructions that performs a specific task when executed by a computer. Most computer devices require programs to function properly.
            A computer program is usually written by a computer programmer in a programming language. From the program in its human-readable form of source code, a compiler or assembler can derive machine code—a form consisting of instructions that the computer can directly execute.
            There are also bad programs, called malware, written by people who want to do bad things to a computer. Some are spyware, trying to steal information from the computer. Some try to damage the data stored on the hard drive. Some others send users to web sites that offer to sell them things. Some are computer viruses or ransomware.

                A Bit represents a

                Pakexammcq Basic IT 0

                A. Decimal Digit
                B. Binary Digit
                C. Octal Digit
                D. Hexadecimal Digit

                Answer & Solution
                Option: B
                Explanation :A bit (short for binary digit) is the smallest unit of data in a computer. A bit has a single binary value, either 0 or 1. Although computers usually provide instructions that can test and manipulate bits, they generally are designed to store data and execute instructions in bit multiples called bytes. In most computer systems, there are eight bits in a byte. The value of a bit is usually stored as either above or below a designated level of electrical charge in a single capacitor within a memory device.
                Half a byte (four bits) is called a nibble. In some systems, the term octet is used for an eight-bit unit instead of byte. In many systems, four eight-bit bytes or octets form a 32-bit word. In such systems, instruction lengths are sometimes expressed as full-word (32 bits in length) or half-word (16 bits in length).

                  B. Memorized
                  C. Reduced to a series of logical steps
                  D. Coded



                  Answer & Solution
                  Option: C
                  Explanation :A computer is capable of performing any task that can be Reduced to a series of logical steps.
                  In reality, computers are not very smart on their own. In order to perform all the tasks, humans fed a series of instructions into a computer that tells him how to behave and perform when faced a particular type of problem. Moreover, these series of instructions are known as a computer program or software. The process of feeding or storing instructions into the computer is known as computer programming. The person who knows how to write a computer program correctly is known as a programmer.
                  Most importantly computer can’t understand English, Urdu or any other common language. Computer have their own special languages, designed by computer scientists. Programmers write computer programs in these special languages called programming languages. Java, C, C++, C#, Python are some of the most commonly used programming languages. Therefore, computer is capable of performing any task that can be Reduced to a series of logical steps.
