Explanation

Yottabyte is the largest size of computer memory.

Terabyte is the largest measure of computer memory. The terabyte is a multiple of the unit byte for digital information.

The prefix tera represents the fourth power of 1000, and means 10¹² in the International System of Units, and therefore one terabyte is one trillion bytes.

Explanation

So Utility Bus is not a type of bus used in computer architecture, hence option 4 is the correct answer.

Address bus - carries memory addresses from the processor to other components such as primary storage and input/output devices. 

Data bus - carries the data between the processor and other components. 

Control bus - carries control signals from the processor to other components.

Explanation

The Cray T90 series was the last of a line of vector processing supercomputers manufactured by Cray Research, Inc, superseding the Cray C90 series.

Explanation

Flat panel displays are used to provide the alpha-numeric display information on laptop computers, automobile and airplane instrument panels, calculators, gas pumps, and many other products requiring the digital display of information.

Liquid crystal displays (LCDs) are by far the most prevalent FPD in use today.

Explanation

A set of instructions that directs a computer's hardware to perform a task is called a program, or software program.

The two main types of software are system software and application software

Explanation

A fingerprint scanner is indeed a type of device that recognises and verifies a person's fingerprints in order to allow or refuse the use of a physical space or computer system.

Explanation

The control unit of the central processing unit regulates and integrates the operations of the computer.

Explanation

An element of an array is identified using its subscript (also called an index).

The subscript indicates the position of the element within the array, with most programming languages starting the index at 0.

Explanation

Arithmetic operations are performed by the ALU

ALU stands for Arithmetic & Logical Unit. 

This is the core component responsible for executing arithmetic (ADD, SUB, etc.) and logical (AND, OR, NOT) operations.

The ALU is housed within the CPU, which acts as the "brain" of the computer.

Explanation

To determine the efficiency of an algorithm the time factor is measured by counting number of key operations
