IT &computer MCQ section 1 MCQ Questions & Answers Detailed Explanation

Answer: (a)

The basic method for implementing paging involves breaking physical memory into fixed-sized blocks called frames and breaking logical memory into blocks of the same size called pages.

When a process is to be executed, its pages are loaded into any available memory frames from the backing store. The backing store is divided into fixed-sized blocks that are of the same size as the memory frames.

Answer: (a)

EKA (the Sanskrit name for number one) was ranked fourth fastest supercomputer in the world in November 2007. It was built by the supercomputer facility at Computational Research Laboratories (CRL), a wholly-owned subsidiary of Tata Sons, in Pune.

A Hewlett-Packard Cluster Platform 3000 BL460c system, EKA uses nearly 1,800 computing nodes and has a peak performance of 170 teraflops.

The CPU (Central Processing Unit) is commonly referred to as the “brains” of a computer since it 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 CPU is also known as the processor or microprocessor.

Answer: (b)

One of the common forms of representing remote sensing data as the information is in the form of thematic maps, by means of visual or computer classification.

However, thematic maps are not an end in themselves and are only the starting point for a variety of applications to which remote sensing data can be potentially used.

Answer: (c)

Garbage collection involves traversing the entire file system, marking everything that can be accessed. Then, a second pass collects everything that is not marked onto a list of free space.

Garbage collection for a disk-based file system, however, is extremely time-consuming and is thus seldom attempted. Garbage collection is necessary only because of possible cycles in the graph.
