The various generations of computers are listed below:

GUI is NOT an image or a graphic file format.

Important Points

• GUI or Graphic user interface has nothing to do with graphic files as it is a type of interface which allows users to interact through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation.

Additional Information

• PNG or portable network graphics is an extension given to a graphic file.
• It was created to replace another format i.e. GIF or Graphic interchange format.
• BMP or Bitmap file is another extension used to create usually image files.

A window is an area on the screen that displays information for a specific program. This often includes the user interface GUI as well as the program content. Windows are used by most applications as well as the operating system itself.

The correct option is (2)

Microsoft

Concept:-

Bing, a search engine launched in 2009 by the American software company Microsoft Corporation.

Important Points

• Microsoft is the owner of Bing. Microsoft, a competitive competitor in the high-tech industry, developed Bing to directly compete with the Google search engine.
• Bing is what Microsoft refers to as a "decision engine," which means that it works to comprehend users' search terms and provide better search results than a standard search engine, assisting users in making smarter choices.
• Microsoft, more than any other firm, has helped customers find ways to incorporate computing into their daily lives through its marketing and products.

Additional Information yahoo!:- Yahoo is a media and technology firm that offers users a variety of digital platforms, goods, and services.

Google:- Google is a search engine that was created in 1996 as a research project at Stanford University by Sergey Brin and Larry Page to locate files on the internet.

AOL:- AOL is a New York City-based American web portal and online service provider. The present iteration of Yahoo Inc. markets the brand.

The correct answer is option 2.

Key PointsOption 1: The username and the domain name are separated by @ (at) symbol.

True, The @ (at) symbol is used to separate the user id from the domain name in the e-mail address.

Ex: 

operations@testbook.com

ram@gmail.com

Here user-id is operations and ram.

The domain is Gmail and testbook.

Option 2: E-mail addresses are case-sensitive.

False, Email addresses are not case sensitive. Having letters in all lowercase makes the email address easier to read, but the oversight won't stop your messages from being delivered.

Hence the correct answer is i is true, ii is false.

The correct answer is RAM.

Key Points

• The word RAM stands for Random Access Memory. It is a very fast internal memory of the CPU. It holds data temporarily. After switching off the computer, data are deleted from the RAM. A CPU directly interacts with RAM to access data during a program’s execution. There are two variants of RAM. These are SRAM and DRAM.
• The word SRAM stands for Static Random Access Memory. The SRAM is comparatively the fastest memory. SRAM chips use a matrix of 6-transistors and no capacitors. There is an additional area within the matrix, thence SRAM uses a lot of chips than DRAM for an equivalent quantity of space for storing, creating the producing prices higher. SRAM is therefore used as cache memory and has no time access. The word DRAM stands for Dynamic Random Access Memory. DRAM always refresh itself to maintain the organised data. This is done by putting the memory on a refresh circuit that rewrites the information many hundred times per second. DRAM is employed for many system memory because it is affordable and tiny in size. DRAMs are created from memory cells, that are composed of 1 capacitor and one electronic transistor.

Thus the correct answer is RAM.

 Additional Information

• ROM: The word ROM stands for Read Only Memory. It is permanent memory that the user will solely read but cannot write of it. This sort of memory is non-volatile. The data is kept for good in such recollections throughout manufacture. A memory stores such directions that are needed to begin a computing system. This operation is remarked as bootstrap. Memory chips don't seem to be solely utilized in the computing system however conjointly in different electronic things like cleaning machines and microwave ovens. MROM, PROM, EPROM and EEPROM are the types of ROM.
• Hard disk: The hard disk is recognised as secondary memory. It is permanent in nature. The size of the hard disk is depending on the users' requirements.
• Magnetic tape: The magnetic tape is the primary storage unit which is circular in size. Audio files, video files are recorded by using the magnetic tapes.

A number system includes the number of independent digits used in the number system (the base), the place values of the different digits constituting the number and the maximum numbers that can be written with the given number of digits.

The Binary Number System: The binary number system with only two independent digits, 0 and 1, is a base-2 number system. All larger binary numbers are represented in terms of ‘0’ and ‘1’.

Decimal to Binary Conversion:

Step 1: Divide 10 by 2 to get the Quotient. Keep the Whole part for the next step and set the Remainder aside.

10 / 2 = 5 with 0 remainder

Step 2: Divide the Whole part of the Quotient from Step 1 by 2. Again, keep the Whole part and set the Remainder aside.

5/ 2 = 2 with 1 remainder

Step 3: Repeat Step 2 above until the Whole part is 0.

2 / 2 = 1 with 0 remainder

1 / 2 = 1 with 1 remainder

Step 4: Write down the Remainders in reverse order to get the answer to 10 as a binary.

When we put the remainders together in reverse order, we get the answer 1010

Hence, the binary equivalent of decimal number 10is 1010.

NOTE:

The decimal number system has a base of 10 as it has 10 independent digits, i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.  The octal and hexadecimal number systems have a radix (or base) of 8 and 16, respectively.

The Math and Trigonometric functions available in MS-Excel 365 include:

• ABS function: Returns the absolute value of a number.
• Trigonometric functions: These include SIN, COS, TAN, ASIN, ACOS, and ATAN, which are used to calculate the sine, cosine, tangent, arcsine, arccosine, and arctangent of an angle.
• LOG function: Returns the natural logarithm of a number.
• EXP function: Returns e raised to the power of a given number.
• SQRT function: Returns the square root of a number.
• RAND function: Returns a random number between 0 and 1.
• INT function: Rounds a number down to the nearest integer.
• ROUND function: Rounds a number to a specified number of decimal places.
• CEILING and FLOOR functions: Round numbers up or down to the nearest integer or multiple of a given value.
• POWER function: Raises a number to a specified power.
• MOD function: Returns the remainder when one number is divided by another.
• SUM, AVERAGE, MAX, and MIN functions: These are basic statistical functions used to calculate the sum, average, maximum, and minimum of a range of numbers.

Note: The text function and logical function are not considered Math and Trigonometric functions, but rather fall under the categories of Text and Logical functions, respectively. Financial functions are also not classified as Math and Trigonometric functions, but rather as Financial functions.

Hence, the correct answer is option 2.
