View, edits and file are present on:
- (A) Title bar
- (B) Menu bar
- (C) Tool bar
- (D) Standard bar
Check AnswerExplanation
The right answer here would be the Menu Bar. The Menu Bar is located just below the Title Bar in many applications (Microsoft Word or LibreOffice) and has many of the most common menus that you will see in text format such as File, Edit, and View, which are used to provide you with a way to access many commands.
The Menu Bar contains: The file menu; The edit menu; The view menu; The tools menu; etc.
The Title Bar displays the name of the document you are currently working on and can be found at the top of the application.
The Tool/Standard Bar contains icons that allow you to access most of your commands quickly.
Which function in Microsoft Excel is used to count items in a cell range?
- (A) COUNT
- (B) AVG
- (C) SUM
- (D) MAX
Check AnswerExplanation
In Microsoft Excel, the suitable function to determine how many items are within a range of cells is:
(A) COUNT.
COUNT: Counts only cells with numeric values.
COUNTA: Counts cells not empty for any value (such as text, number, etc.).
COUNTIF: Counts the number of cells based on one criteria only.
Other choices describe different types of calculations included:
AVG (AVERAGE) gives a value that is an average of other like values in one range of cells.
SUM adds all of the values together.
MAX returns the highest number found in a range of cells.
In computing, “NOS” stands for:
- (A) Non-operating software
- (B) Network operating system
- (C) Node open software
- (D) Neutral operating system
Check Answer
- (B) Network operating system
ExplanationA network operating system (NOS), or a network OS, is a type of software that allows workstations, PC’s, and older terminals to communicate through a network. A network operating system is different than a standard operating system because a normal OS manages only the processes and resources of a single computer. A NOS gives multiple users, always connected by a local area network (LAN), access to the protocols and tools required to share information and resources from their own computers to another user’s computer.
Which is the first computer to use ‘stored program concept’?
- (A) MARK-1
- (B) UNIVAC
- (C) ENIAC
- (D) EDSAC
Check AnswerExplanationThe EDSAC (Electronic Delay Storage Automatic Calculator) was a functional full-size stored program computer that went into operation in May 1949. Even though both the EDVAC and the Manchester Small Scale Experimental Machine (SSEM) had used this principle (with the SSEM running the first program in 1948), the EDSAC was the first machine to operate in a routinely how to provide stored program services.
The smallest unit of data in a computer is:
- (A) Bit
- (B) Kilobyte
- (C) Byte
- (D) Nibble
Check AnswerExplanationA single bit is the smallest element of digital data, representing a binary state (i.e., two states), either 0 or 1. Computers process and store information using binary signals that indicate the on or off state of the binary element and are responsible for everything from text to video, with larger data units such as nibbles (4 bits) and bytes (8 bits) being used to group data into meaningful units but the basic element of all data in computing remains the bit (i.e., binary digit).
The starting point of a website is:
- (A) Index
- (B) Java script
- (C) Bookmark
- (D) Home page
Check AnswerExplanation
The website’s primary entrance point, or ‘front door,’ generally provides an overview of the website’s contents and navigation.
Home page: The default landing page of a website that provides an introduction to the website’s content and the ability to navigate to other areas.
Index: Normally, this term refers to the Index File, which is the first file the web server will search for when trying to display the home page.
JavaScript: A language that provides interactivity to websites and can be part of a site but is not the starting point of a site.
Bookmark: A shortcut, saved in a web browser, that allows the user to quickly locate a certain page.
A bit can be _____.
- (A) 0 only
- (B) 1 only
- (C) 1 or 0
- (D) 1 and 0
Check AnswerExplanationThe smallest unit of data in computer technology is a value called a bit or a binary digit. A bit can represent a value of zero (off) or one (on). In the world of computers and digital communications, a bit represents the very first data unit used for all other data units. A bit represents two states, although they can only be in one of those states at any given time.
A small, high-speed memory inside the CPU is:
- (A) Register
- (B) RAM
- (C) ROM
- (D) Cache
Check AnswerExplanation
The correct answer is Registers – they are the most immediate form of storage and located directly in the CPU. Registers are the fastest and smallest types of storage and hold all data being processed in real time within the CPU (central processing unit).
Cache is high speed memory, but it is not on the CPU. Therefore, cache can be confused with Registers but should not be compared because Cache contains different types of memory with different speeds corresponding to L1/L2/L3 location near the CPU which helps to facilitate faster access to RAM.
RAM is main memory (larger than either cache or registers), but it is also slower than either; it exists off chip from the CPU.
ROM is permanent, read-only memory.
Which of the following is not a mouse technology?
- (A) Optical
- (B) Mechanical
- (C) Motorised
- (D) Optical-mechanical
Check AnswerExplanation
Computer mice are generally classified as three types based on the technology that is used to detect cursor movement and to track the position of the cursor on the computer screen (optical, mechanical, and optical-mechanical).
Mechanical mice utilise a ball to measure the movements of the mouse. Optical mice have an illuminated optical sensor (light) to detect the mouse’s motion. Optical-mechanical mice are hybrid devices, using both optical and mechanical technologies for precise cursor tracking.
On the other hand, motorised is not a valid mouse technology and has no bearing on how the mouse detects movement, so it is the best answer.
The ‘Unit’ that control all parts of computer is:
- (A) ALU
- (B) CPU
- (C) RAM
- (D) ROM
