A combination of 16 bites is called _____.
- (A) Bit
- (B) Byte
- (C) Nibble
- (D) Word
- (D) Word
16 bits can be described as a “Word”; but the specific options on this list offer up an interesting perspective – while “Word” is the common technical term for 16 bits in many architectures, the given options all come down to one thing – (D) Word is most frequently used to describe 16 bits in terms of basic data units.
A technique for providing fast direct access to a specific stored of a given value is called:
- (A) Fetching
- (B) Batch access
- (C) Hashing
- (D) Tracking
- (C) Hashing
The technique of Hashing involves using the concept of a hash function to convert a key (or value) to an assigned memory space/ location or address where it can be found (usually referred to as a “bucket”). It allows users to directly access the stored data from its assigned location instead of searching through either an index or the entire database; therefore, it allows the user very quick (efficient) and nearly instantaneous access to the stored information.
‘Shutdown’ option is available on:
- (A) Start menu
- (B) Task bar
- (C) Status bar
- (D) Title bar
- (A) Start menu
Which software is used to search and view web-pages?
- (A) HTML
- (B) Web server
- (C) Web browser
- (D) Window explorer
- (C) Web browser
A web-browser is a computer program that allows you to find, view and move through different types of information available on the Internet known as the World Wide Web. When you type in a web address or search phrase, your web-browser goes to that specified web server, gets the data in the form of usually an HTML page, and shows (creates) it on your screen so that you can read it. The most popular web-browsers are Google Chrome, Mozilla Firefox, Safari, and Microsoft Edge.
Which of the following is not related to e-mail?
- (A) Bcc
- (B) Pen
- (C) Pine
- (D) Spam
- (B) Pen
Computers calculate numbers in what mode?
- (A) Fraction
- (B) Binary
- (C) Octal
- (D) Decimal
- (B) Binary
Computers operate using the binary number system, which consists of only 0s and 1s, because their hardware relies on electrical signals that have two states: ON and OFF. Decimal and octal systems together with fractional numbers serve as human-readable formats that systems convert into binary for their internal computations.
_____ uses information systems to do an activity cheaper, faster, accurately and consistently.
- (A) Genetics
- (B) Automatic
- (C) Robotics
- (D) Automation
- (C) Robotics
Robotics fieldwork utilizes information systems for the development of robotic systems which operate with enhanced operational efficiency through lower operational costs and shorter time requirements and superior accuracy and constant performance. The field of automation applies technological solutions to execute physical tasks and complicated processes with reduced need for human participation.
In computing, what is the full form of ‘GB’?
- (A) Gogobyte
- (B) Gigabyte
- (C) Grand byte
- (D) Gaga byte
- (B) Gigabyte
Which is a volatile memory?
- (A) ROM
- (B) BIOS
- (C) RAM
- (D) PROM
- (C) RAM
RAM (Random Access Memory) is the primary workspace of a computer. It stores the data and instructions that the CPU is actively using. It is designed for high-speed reading and writing, but it cannot retain data without a constant electrical charge. In computing volatile memory is a type of storage. It needs power to keep the information stored. If the power goes out or you turn off the computer all the data, in memory disappears right away. Volatile memory loses all its data when the computer is shut down.
“Binary Codes” as used in computer sciences are codes made up of which of the following two numbers?
- (A) 0 and 1
- (B) 0 and 9
- (C) 1 and 3
- (D) 0 and 2
- (A) 0 and 1
