Computer fundamental MCQ Questions and answers- Technical Aptitude

Magnetic storage devices can represent binary 0 by the absence of Magnetic tape.

Most widely used secondary storage devices are magnetic tapes, magnetic disks and floppy disks. It is not directly accessible by the CPU. Computer usually uses its input / output channels to access secondary storage and transfers the desired data using intermediate are a in primary storage.

Storage Capacity of Floppy Disc = 1.44 Megabytes.
Storage Capacity of CD-ROM = 650 Megabytes (Approx.).

A CD-ROM, is a pre-pressed optical compact disc which contains data. The name is an acronym which stands for Compact Disc Read-Only Memory. Computers can read CD-ROMs, but cannot write to CD-ROMs which are not writable or erasable.

PASCAL languages is more suited to a structured program.
Pascal is an imperative and procedural programming language, which Niklaus Wirth designed in 1968–69 and published in 1970, as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honor of the French mathematician, philosopher and physicist Blaise Pascal.

A computer assisted method for the recording and analyzing of existing or hypothetical systems is Data flow

The brain of any computer system is CPU.
CPU : A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

The term "fifth generation" was intended to convey the system as being advanced. Whereas previous computer generations had focused on increasing the number of logic elements in a single CPU, the fifth generation, it was widely believed at the time, would instead turn to massive numbers of CPUs for added performance.

Prolog, Python, Lisp, Java, and C++ are major AI programming language used for artificial intelligence capable of satisfying different needs in development and designing of different software.

Prolog : Prolog is a declarative language where programs are expressed in terms of relations, and execution occurs by running queries over these relations. Prolog is particularly useful for symbolic reasoning, database and language parsing applications. Prolog is widely used in AI today.

The tracks on a disk which can be accessed without repositioning the R/W heads is Cylinder
