2041. LSI in chip technology stands for
| Answer : Option A |
| Explanation : |
| LSI stands for Large Scale Integration, the process of integrating or embedding thousands of transistors on a single silicon semiconductor microchip. LSI technology was conceived in the mid-1970s when computer processor microchips were under development.

2047. Which is not a basic function of a computer?
| Answer : Option A |
| Explanation : |
| Computers lane four basic functions : they take in raw data i.e, unorganized facts & figures (input) ; they store data (storage) ; they manipulte data (processing) and they provide the user with meaningful informationn (output) for decision–making. |
2048. What is the name for the process that is used to convert a series of instructions, or program, written in a high-level language into instructions (or a program) that can be run on a computer ?
| Answer : Option A |
| Explanation : |

2049. Computers use the _____ number system to store data and perform calculations.
| Answer : Option C |
| Explanation : |
| Binary numbers are closely related to digital electronics. With digital electronics, a '1' means that current is present and a '0' means it is not present. The different parts of a computer communicate through pulses of current (1s and 0s) . Computers can calculate complex equations and perform complex calculations. Calculating using only 1s and 0 s is called Binary system. A computer can process only 1s and 0 s. |
2050. What is the logical address of a Webpage?
| Answer : Option D |
| Explanation : |
| Web addresses are recorded in a Uniform Resource Locator (URL), a logical address of a web page that can always used to dynamically retrieve the current physical copy over the Internet.

2053. A(n)_____is a program that makes the computer easier to use.
| Answer : Option B |
| Explanation : |
| A utility program allows a user to perform maintenancetype tasks usually related to managing a computer, its devices or its programs. This makes computer easier to use, eg. Disk fragmenter, file compression, etc. |
2054. Checking that a pin code number is valid before it is entered into the system in an example of
| Answer : Option B |
| Explanation : |
| When user enter data in an application, it is necessary to verify that the data is valid before the application uses. This is called Data validation. Data validation may require that certain text fields not be zero length, that a field is formatted as a telephone number or other type of wellformed data, or that a string not contain any unsafe character that could be used to compromise the security of a database. |
2055. What is the full form of OSI?
| Answer : Option D |
| Explanation : |
| In computing, OSI stands for Open Systems Interconnection. It is a conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into abstraction layers. The model is a product of the Open Systems Interconnection project at the International Organization for Standardization (ISO). |
