The Correct answer is Home Page.

Key Points

• A home page also refers to the first page that appears upon opening a web browser, sometimes called the start page, although the home page of a website can be used as a start page.
• A home page on a website serves as a launching pad to other products and services.

Additional Information

• An identification page printed at the beginning of a print job by many print spoolers. It serves as a title page and separator between print jobs.
• The Banner page is the first page of a print job used as a separator of print jobs and used to identify the originator of the print job request.
• A Master Page is a nonprinting page that you can use as the template for the rest of the pages in your document.
• Master pages can contain text and graphic elements that will appear on all pages of a publication (i.e. headers, footers, page numbers, etc.).

The correct answer is Fourth

Key Points

• Computer generations refer to technological developments in computing over the years which fundamentally altered the way computers operate. The first generation of computers operated on vacuum tubes, second-generation computers on transistors and diodes, third-generation computers on integrated circuits, and the fourth generation on microprocessors.

Additional Information

• A microprocessor is a component that performs the instructions and tasks involved in computer processing. In a computer system, the microprocessor is the central unit that executes and manages the logical instructions passed to it.
• A microprocessor may also be called a processor or central processing unit, but it is actually more advanced in terms of architectural design and is built over a silicon microchip.
• A microprocessor is the most important unit within a computer system and is responsible for processing the unique set of instructions and processes. A microprocessor is designed to execute logical and computational tasks with typical operations such as addition/subtraction, interprocess and device communication, input/output management, etc. A microprocessor is composed of integrated circuits that hold thousands of transistors; exactly how many depends on its relative computing power.
• Microprocessors are generally classified according to the number of instructions they can process within a given time, their clock speed measured in megahertz, and the number of bits used per instruction.

The correct answer is Voice recognition.

• A voice recognition module is a device that converts spoken words into information that the computer can recognize and process.
• Alternatively referred to as speech recognition, voice recognition is a computer software program or hardware device with the ability to decode the human voice.
• Voice recognition is commonly used to operate a device, perform commands, or write without having to use a keyboard, mouse, or press any buttons.
• Today, this is done on a computer with ASR (automatic speech recognition) software programs.

Additional Information

The correct answer is Preventing unauthorized access.

Key Points

• A firewall is a kind of security-conscious type of hardware or software that stays between the computer and our network with a primary task: preventing malicious software from reaching us.
• In other words, we can say that the firewall works like a security guard between the Internet and our local area network (LAN). All network traffic passing through the LAN must face the firewall, which restricts unauthorized access to the network.

Additional Information 

• Following are the types of Firewalls -

1. Packet-filtering firewall: It checks every packet that passes the firewall and examines the packet as per the set of rules that the user sets up. If the packet gets to pass the test, it’s allowed to go through. If the packet fails to pass the test then it is rejected. Packet filters are the most inexpensive variety of firewalls. That is why packet-filtering firewalls are used very commonly.
2. Stateful packet inspection (SPI): It is installed in accordance with simple packet filtering. A firewall having Stateful packet checking looks at packets in clusters instead of doing individually. It maintains the record of all those packets have crossed through the firewall and can create patterns that indicate unauthorized entry.
3. Deep packet inspection (DPI): It is the actual data of the packets is checked so viruses, spam, and other harmful content can be restricted. DPI also enables practices, such as data mining, eavesdropping, and content censorship, which make its way through a controversial subject.

The correct answer is option 4, i.e. Real Time.

• Real Time
• ​A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time applications that process data as it comes in, typically without buffer delays.
• The time interval required to process and respond to inputs is very small and measured in tenths of seconds or shorter increments of time.
• Distributed
• A distributed operating system is a software over a collection of independent, networked, communicating, and physically separate computational nodes.
• They handle jobs which are serviced by multiple CPUs.
• Batch
• This type of operating system does not interact with the computer directly.
• There is an operator which takes similar jobs having same requirement and group them into batches.
• Multi tasking
• ​Multitasking operating system provides the interface for executing the multiple program tasks by single user at a same time on the one computer system.
• In a multitasking operating system, more than one task is executed at the same time.

The correct answer is option 3, i.e. Scanner.

• Scanner is an input device, which works more like a photocopy machine. It is used when some information is available on paper and it is to be transferred to the hard disk of the computer for further manipulation.
• Scanner captures images from the source which are then converted into a digital form that can be stored on the disk. These images can be edited before they are printed.
• Digitizer is an input device which converts analog information into digital form.
• Microphone is an input device to input sound that is then stored in a digital form.
• Track ball is an input device that is mostly used in notebook or laptop computer, instead of a mouse. This is a ball which is half inserted and by moving fingers on the ball, the pointer can be moved.
• Light pen is a pointing device similar to a pen. It is used to select a displayed menu item or draw pictures on the monitor screen. It consists of a photocell and an optical system placed in a small tube.

The correct answer is Machine Language.

• A machine language is a low-level programming language used to directly control a computer's Central Processing Unit.
• It comprises of a long sequence of binary zeroes and ones (bits). It is the only language a computer is capable of understanding.
• High-level languages such as Swift and C++ must be compiled into machine language before the code is run on a computer.
• Machine language is normally displayed in the hexadecimal form so that it is a little bit easier to read.

The Correct Answer is Option 2 i.e Input.

• Digitizer is a computer input device that receives analog information, such used to capture handwritten signatures and data or images from taped papers and records it digitally thereby converting it to digital format.
• An input device sends information to a computer system for processing, and the device reproduces or displays the results of that processing is an output device.
• Input devices include Keyboard, Mouse, Scanner, Microphone, Digital Cameras, Barcode reader, digitizer, Webcam, etc.
• Few examples of output devices include Printers, Projector, Plotters, monitors, Speakers, Head Phone, etc.

Virus

A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code

Important Point:

• Spam is any kind of unwanted, unsolicited digital communication, often an email, that gets sent out in bulk. Spam is a huge waste of time and resources.
• Spyware is unwanted software that infiltrates your computing device, stealing your internet usage data and sensitive information. Spyware is classified as a type of malware.
• Adware, or advertising supported software, is software that displays unwanted advertisements on user computer

The correct answer is Not held permanently, only temporary

• The full form of RAM is Random Access Memory. The information stored in this type of memory is lost when the power supply to the PC or laptop is switched off. The information stored in RAM can be checked with the help of BIOS. It is generally known as the main memory or temporary memory or cache memory or volatile memory of the computer system.
• Two main types of RAM are:

1. Static RAM: Static RAM is the full form of SRAM. In this type of RAM, data is stored using the state of a six transistor memory cell. Static RAM is mostly used as a cache memory for the processor (CPU).
2. Dynamic RAM: DRAM stands for Dynamic Random Access Memory. It is a type of RAM which allows you to stores each bit of data in a separate capacitor within a specific integrated circuit. Dynamic RAM is a standard computer memory of the many modern desktop computers. This type of RAM is a volatile memory that needs to be refreshed with voltage regularly. Else it loses the information stored on it.
