The correct answer is Only (ii).

Key Points

• In MS-Excel, an intersecting grid of a row and column is called a cell.
• Columns are identified by letters (A, B, C), while rows are identified by numbers (1, 2, 3).
• Each cell has its own name or cell address based on its column and row.
• ​Hence statement 1 is true.
• In MS-Excel, the address of any cell starts with "A1‟. Hence statement 2 is false.

Additional Information 

• The Excel ADDRESS function returns the address for a cell based on a given row and column number.
• For example, =ADDRESS(1,1) returns $A$1.
• ADDRESS can return an address in relative or absolute format and can be used to construct a cell reference inside a formula.
• A cell address in the current or given worksheet.

The correct answer is 2.

Key Points

• The result of the MS-Excel formula-SUM(2−3^2, 9) is 2.
• Firstly 3^2 will be solved and it is equal to 9------SUM(2-9,9)
• Then 9 is subtracted from 2 which equals -7 -----SUM(-7,9)
• Then lastly both -7 and 9 will be added and it is equal to 2.

Additional Information 

• The Excel SUM function returns the sum of values supplied.
• These values can be numbers, cell references, ranges, arrays, and constants, in any combination.
• SUM can handle up to 255 individual arguments.
• Purpose 
• Add numbers together
• Return value 
• The sum of values supplied.
• Syntax 
• =SUM (number1, [number2], [number3], ...)
• Arguments 
• number1 - The first value to sum.
• number2 - [optional] The second value to sum.
• number3 - [optional] The third value to sum.

The correct answer is Ctrl + =.

Key Points

• A subscript is a number, figure, symbol, or indicator that is smaller than the normal line of type and is set slightly below it.
• For ex- Formula of Carbon Dioxide is CO_2.
• The shortcut key to create subscript in MS-Word is Ctrl + =.
• A superscript is a number, figure, symbol, or indicator that is smaller than the normal line of type and is set slightly above it.
• For ex- ion of sodium is Na^​+1.

Additional Information 

The correct answer is Microphone.

Key Points

• Microphone
• A microphone, colloquially called a mic or mike (/maɪk/).
• It is a device that converts sound into an electrical signal.
• Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, radio, and television broadcasting.
• They are also used in computers for recording voice, speech recognition, VoIP, and for non-acoustic purposes such as ultrasonic sensors or knock sensors.

Additional Information 

• Optical character recognition
• Optical character recognition or optical character reader is the electronic or mechanical conversion of images of typed, handwritten, or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo or from subtitle text superimposed on an image.​
• Bar code reader
• A barcode reader (or barcode scanner) is an optical scanner that can read printed barcodes, decode the data contained in the barcode and send the data to a computer.
• Like a flatbed scanner, it consists of a light source, a lens, and a light sensor translating for optical impulses into electrical signals.
• Additionally, nearly all barcode readers contain decoder circuitry that can analyze the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.
• Optical mark recognition
• Optical mark recognition (also called optical mark reading and OMR) is the process of capturing human-marked data from document forms such as surveys and tests.
• They are used to read questionnaires, multiple-choice examination papers in the form of lines or shaded areas.

The correct answer is Hard Disk.

Key Points

• Hard Disk
• A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electromechanical data storage device that stores and retrieves digital data using magnetic storage and one or more rigid rapidly rotating platters coated with magnetic material.
• The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces.
• Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order.

Additional Information 

• DRAM
• Dynamic random access memory (DRAM) is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function.
• DRAM is a common type of random access memory (RAM) that is used in personal computers (PCs), workstations, and servers.
• SDRAM
• SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for.
• This tends to increase the number of instructions that the processor can perform in a given time.
• SRAM
• Static random-access memory is a type of random-access memory that uses latching circuitry to store each bit.
• SRAM is a volatile memory, data is lost when power is removed.
• The term static differentiates SRAM from DRAM which must be periodically refreshed.

The correct answer is EPROM.

Key Points

• EPROM
• An EPROM (rarely EROM), or erasable programmable read-only memory**, is a type of programmable read-only memory (PROM)** chip that retains its data when its power supply is switched off.
• Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile.
• It is an array of floating-gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in digital circuits.
• Once programmed, an EPROM can be erased by exposing it to a strong ultraviolet light source (such as from a mercury-vapour lamp).
• EPROMs are easily recognizable by the transparent fused quartz window on the top of the package, through which the silicon chip is visible, and which permits exposure to ultraviolet light during erasing.

Additional Information 

• DRAM
• Dynamic random access memory (DRAM) is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function.
• DRAM is a common type of random access memory (RAM) that is used in personal computers (PCs), workstations, and servers.
• EEPROM
• EEPROM (electrically erasable programmable read-only memory) is a user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage.
• Unlike EPROM chips, EEPROMs do not need to be removed from the computer to be modified.
• However, an EEPROM chip has to be erased and reprogrammed in its entirety, not selectively.
• PROM
• A programmable read-only memory is a form of digital memory where the setting of each bit is locked by a fuse or anti-fuse.
• It is one type of read-only memory.
• The data in them are permanent and cannot be changed.

The correct answer is A zip file can contain both pdf and doc files.

Key Points

• ZIP is an archive file format that supports lossless data compression.
• A ZIP file may contain one or more files or directories that may have been compressed.
• The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common.
• This format was originally created in 1989 and was first implemented in PKWARE, Inc.'s PKZIP utility, as a replacement for the previous ARC compression format by Thom Henderson.
• A zip file can contain both pdf and doc files.

Additional Information 

• Not only do folders hold files, but they also can hold other folders.
• A folder within a folder is usually called a subfolder.
• You can create any number of subfolders, and each can hold any number of files and additional subfolders.
• **A file can not contain another file just like a folder can contain another folder. **Hence option 2 is false.
• A folder can be compressed as a zip file.
• A folder can have both zip and pdf files. Hence option 3 and option 4 are false.
