extends is used to inherits properties from one class into another.

Inheritance supports the concept of hierarchical classification.

Data hiding is a method used in object-oriented programming to hide information within computer code. Objects inside code are not privy to information which is considered hidden. It presents many advantages for programmers because objects are unable to connect to irrelevant data and hackers are less likely to access data.

Data hiding takes specific parts of the code and then conceals those parts from the objects. The objects are not directly accessible in any data that is hidden. If an object is able to access hidden data, it will return an error, and this is because the object cannot see the data.

Direct addressing is possible only when we can afford to allocate an array that has one position for every possible key.

Making the hash function random is not really a good choice, although it is considered one of the techniques to avoid collisions along with chaining and simple uniform hashing. Chaining is the best

In simple chaining, the load factor is the average number of elements stored in a chain and is given by the ratio of a number of elements stored to the number of slots in the array.

When more than one element are competing for the same bucket in the hash table, this condition is known as the Collision.

By definition

When more than one element are competing for the same bucket in the hash table, this condition is known as the Collision.

Seeking refers to the precise physical placement of the disc's read/write head. The seek time is the length of time it takes the read/write head of the disc to move from one area to another.

The cost of computers has decreased as a result of the IC's use in them. It is a transistor- and electrical circuit-integrated electronics chip that is very tiny. It's a tiny chip, really.

The best choice is tertiary storage. It is something that a typical home computer never encounters because it is employed in the fields of enterprise storage and scientific computing on huge computer systems and business computer networks.

LOGIN was supposed to be sent, according to Kleinrock, but the system malfunctioned after the first two letters were sent. As a result, Kleinrock said, "the first Internet message was 'LO', as in 'Lo and behold!'."

Pascal lets programmers create dynamic and recursive data structures such as lists, trees, and graphs by defining complicated structured data types. Records, enumerations, subranges, dynamically allocated variables with accompanying pointers, and sets are all available in Pascal.

Disk access time depends on several parameters and the interval is the disk access time. Access Time + Data Transfer Time = Disk Access Time 1. Access Time: Access Time is the setup period prior to the data transfer itself. The next instruction can be read from memory if, for instance, the read/write head is on track 1 but we need to read data from another track or segment.

It's a personal assistance package that lets you do just that. It aids in the organization and management of their calendars, contacts, funds, and a glossary of key phrases.

OCR is the mechanical or electrical conversion of typed, handwritten, or printed text images from scanned documents, photographs of documents, photographs of scenes, or text superimposed on images into machine-encoded text.

The defragmentation tool, known as Disk Defragmenter, is already included in Windows, thus downloading additional software is not necessary. Both internal and external hard drives can be defragmented and have schedules established.

Modem is not used in LAN

The correct answer is Writing. When referring to data or storage devices, writing is taking information and moving it to an alternate location.

1 byte=8 bits

1bit = ⅛ byte

8192 bits = 8192/8 bytes

=1024 bytes

All the mentioned options are correct for primary memory.

A collection of related records is called a database. A database is defined as an organized collection of data that is stored and accessed electronically from a computer system.

Telnet is the answer. It is a service that enables the user to log into another computer somewhere on the Internet.

Internet navigator is not a browser software.

Ans : C

Explanation : Analogue Computer, Digital Computer, Hybrid Computer are the three types on the basis of data handling capabilities and size.

Supercomputer, Mainframe Computer, Minicomputer, Workstation and Micro Computers are the five types on the basis of size.

A Redundant Array of Independent Disks (RAID) is a collection of hard drives, one or more controller cards, and embedded software to increase the reliability and redundancy of data storage on hard drives.

SMTP stands for Simple Mail Transfer Protocol. SMTP is a set of communication guidelines that allow software to transmit an electronic mail over the internet is called Simple Mail Transfer Protocol. It is a program used for sending messages to other computer users based on e-mail addresses.

OS-2 is a series of computer operating systems, initially created by Microsoft and IBM under the leadership of IBM software designer Ed Iacobucci.
