Computer fundamental MCQ Questions and answers- Technical Aptitude

1000 addresses are required for 25 × 40 video RAM. VRAM (video RAM) is a reference to any type of random access memory (RAM) used to store image data for a computer display. All types of VRAM are special arrangements of dynamic RAM (DRAM).

Distributed computing is a model in which components of a software system are shared among multiple computers. Even though the components are spread out across multiple computers, they are run as one system. This is done in order to improve efficiency and performance.

ISO : The International Organization for Standardization is an international standard-setting body composed of representatives from various national standards organizations. Founded on 23 February 1947, the organization promotes worldwide proprietary, industrial and commercial standards.

International Business Machines Corporation (IBM) is an American multinational information technology company headquartered in Armonk, New York, United States, with operations in over 170 countries.

The new Zilog Z80 processor (rather than the more common Intel 8080), 4 KB DRAM standard memory (when many 8-bit computers shipped with only 1 KB RAM), small size and desk footprint, floating-point BASIC programming language, standard 64-character/line video monitor.

101110 is 56 in octal form
(101110)₂ = (56)₈
Step 1: Write down the binary number (101110)₂
Group all the digits in sets of three starting from the LSB (far right). Add zeros to the left of the last digit if there aren't enough digits to make a set of three.
= 101 110
Step 2: Use the table below to convert each set of three into an octal digit. In this case,
101 = 5, 110 = 6.
So, the number 56 is the octal equivalent to 101110 in binary.
To convert from binary to octal use the following table:

Bin:	000	001	010	011	100	101	110	111
Octal:	0	1	2	3	4	5	6	7

A symbol that modifies an action is known as Modifier. A modifier is a word, phrase, or clause that modifies that is, gives information about another word in the same sentence. For example, in the following sentence, the word "burger" is modified by the word "vegetarian": Example: I'm going to the Saturn Café for a vegetarian burger.

The EDSAC is a large-scale electronic calculating machine in which ultrasonic delay units are used for storage of orders and numbers. It is serial in operation and works in the scale of two. Punched tape is used for input and a teleprinter for output.

RAM is the main memory in a computer. It is much faster to read from and write to than other kinds of storage, such as a hard disk drive (HDD), solid-state drive (SSD) or optical drive. Random Access Memory is volatile.

A false statement is a statement that is not true. Although the word fallacy is sometimes used as a synonym for false statement, that is not how the word is used in philosophy, mathematics, logic and most formal contexts. A false statement need not be a lie.
