Computer Fundamental & Internet

HTTP stands for Hyper Text Transport Protocol. This protocol is used for communication between a client and a server over the internet. It is the foundation of data communication for the World Wide Web. HTTP allows for the retrieval and display of hypertext documents, which are commonly referred to as web pages. It is responsible for transmitting data between the client's web browser and the server that hosts the website.

E-commerce refers to the transaction of selling and buying products online. It involves conducting business electronically, allowing customers to browse and purchase products through websites or mobile applications. This term encompasses various online activities such as online shopping, online auctions, and online banking. It has revolutionized the way businesses operate and has become an integral part of the global economy.

CDROM stands for Compact disk read-only memory. It is a storage medium that uses optical technology to read and retrieve data. The term "compact disk" refers to the physical format of the storage medium, which is a flat, circular disc. The term "read-only memory" indicates that the data on the CDROM is permanently written during manufacturing and cannot be altered or erased by the user.

WAIS stands for Wide Area Information Server. This is a correct answer because WAIS is a system that allows users to search and retrieve information from a wide variety of databases located on different servers across the internet. It was developed in the 1990s as an early internet search engine and was particularly useful for accessing and searching large amounts of textual information.

The correct answer is "Beginners' All purpose symbolic instruction code." BASIC is a programming language that was designed to be simple and easy to learn for beginners. It uses English-like commands and is often used for educational and introductory purposes.

PDA stands for Personal Digital Assistant. This term refers to a handheld device that combines computing, telephone, and networking features. It is designed to assist individuals in managing personal information such as contacts, appointments, and tasks. Examples of PDAs include devices like Palm Pilots and Blackberry phones.

The correct answer is "Memory data register". MDR stands for Memory Data Register, which is a temporary storage location in a computer's central processing unit (CPU). It holds the data that is being transferred between the CPU and the computer's memory.

MICR stands for Magnetic Ink Character Reader. It is a technology used in banking to facilitate the processing of cheques. The characters on the bottom of a cheque, which include the account number and routing number, are printed using a special magnetic ink. The MICR technology allows these characters to be read and processed quickly and accurately by machines. Therefore, the correct answer is "Magnetic ink character reader".

A string variable is a type of variable that can hold a sequence of characters. It is represented by an alphabet and an '&' sign at the end. This type of variable is used to store textual data such as names, sentences, or any other combination of characters. It is different from numeric values or characters, as it can store a sequence of characters rather than just a single character or a numerical value. Therefore, the correct answer is string variable.

A chain printer consists of a steel band on which characters are embossed. This band, known as the chain, contains the characters that need to be printed. As the chain rotates, the embossed characters strike an inked ribbon, transferring the ink onto the paper, thus creating the printed output. This mechanism allows for fast and reliable printing, making chain printers suitable for high-volume printing tasks. In contrast, line printers use a line of type to print characters, and drum printers use a rotating drum with characters engraved on its surface. None of these printers use a steel band with embossed characters.

Nicklaus is the correct answer because he is the one who developed the Pascal programming language. Pascal was created in the late 1960s and early 1970s by Niklaus Wirth, a Swiss computer scientist. It was named after the French mathematician and philosopher Blaise Pascal. Pascal was designed to encourage good programming practices and to be a reliable and efficient language for scientific and educational purposes.

An extremely light weight personal computer, typically weighing less than 6 pounds is called a notebook computer. It is a portable device that is smaller and lighter than traditional laptops, making it convenient for users to carry it around. Notebook computers are designed for mobility and are often used for tasks such as internet browsing, word processing, and multimedia consumption.

A station on a network is referred to as a "node". This can be any device such as a dump terminal, printer, or computer machine that is connected to the network.

VLSE stands for Very large scale integrated circuits. This term refers to the design and fabrication of integrated circuits (ICs) that contain a large number of transistors and other electronic components on a single chip. These ICs are used in a wide range of electronic devices, from smartphones and computers to automotive systems and medical equipment. The use of VLSE technology allows for increased functionality and performance in smaller and more efficient devices.

The statement "LET" is used to assign a numerical or a string value to a variable.

Chain printers and serial character printers are types of printers that are used in the world.

There are four types of printers available.

Assembly language is the correct answer because it is a low-level programming language that uses mnemonic codes or opcodes instead of binary machine codes. It provides a more human-readable representation of machine language instructions, making it easier for programmers to write and understand code. High-level languages like C++ or Java are further away from machine code and use more abstract instructions, while machine language directly represents the binary instructions understood by the computer's hardware.

Machine language is the correct answer because it refers to the language in which data is represented using binary code, consisting of ones and zeros. Programs written in machine language can be executed directly by the computer's hardware. Assembly language is a low-level language that uses mnemonic codes to represent machine language instructions. High-level languages are more user-friendly and require a compiler or interpreter to convert the code into machine language. Binary coded language is not a commonly used term in computer science.

The computers of the fourth generation came into use between the years 1976-85. This period marked a significant advancement in computer technology, with the introduction of microprocessors and personal computers. The fourth generation computers were smaller, faster, and more affordable compared to their predecessors. This era also saw the development of graphical user interfaces (GUI) and the beginning of the modern computer era.

COBOL stands for Common Business Operator Language. It is a programming language that was designed for business applications. The term "common" refers to its widespread use across different industries, while "business" indicates its focus on business-oriented applications. The term "operator" refers to the language's ability to perform operations on data. Therefore, the correct answer is Common Business Operator Language.

There are four basic operators in Boolean algebra: AND, OR, NOT, and XOR. These operators are used to manipulate Boolean variables and perform logical operations.

There are three basic types of binary coding used in computers. Binary coding is the representation of data or instructions in binary form, consisting of only 0s and 1s. These three basic types include the binary system (base-2), which is commonly used in computer systems, the hexadecimal system (base-16), which is used for representing large binary numbers in a more compact form, and the ASCII code, which is used for representing characters in computers.

The data read from the memory or that to be written in the memory is placed in the MDR (Memory Data Register). The MDR is a temporary storage location within the computer's memory system that holds the data being transferred between the CPU and the memory. It acts as a buffer, allowing the CPU to access and manipulate the data before it is written back to the memory or used for further processing.

There are five types of ROM in a computer.
