What is a mouse and mention its types in 5-6 sentence?
The computer's mouse controls a graphical mouse pointer or mouse cursor on the screen. When you move the mouse around by rolling it on your desk, the pointer on the screen moves in a similar manner. Roll the mouse left, and the pointer moves left; roll it in circles, and the pointer mimics that action.Here are some of the more basic mouse operations:Point: When you're told to "point the mouse," you move the mouse on the desktop, which moves the mouse pointer on the screen to point at something interesting (or not).Click: A click is a press of the mouse button - one press and release of the main button, the one on the left. This action makes a clicking sound, which is where this maneuver gets its name.Clicking is often done to select something or to identify a specific location on the screen.Right-click: This action is the same as a click, although the right mouse button is used.Double-click: This one works just like the single click, although you click twice in the same spot - usually, rather rapidly.This is most commonly done in Windows to open something, such as an icon. Both clicks must be on (or near) the same spot for the double-click to work.Drag: The drag operation is done to graphically pick up something on the screen and move it. To do that, you point the mouse at the thing you want to drag, press and hold the mouse's button (which "picks up" the object), and then move the mouse to another location. When you move the mouse (and keep the button down), the object moves. To release, or drop, the object, release the mouse button.Right-drag: This action is the same as a drag, but the mouse's right button is used.Many of these basic mouse operations can be combined with keys on the keyboard. For example
What is the difference between an icon and mouse pointer?
An icon is an image representation of a program, a shortcut, or a script. For instance on your desktop those pictures that are on programs, and shortcuts such as My computer are icons. So to wrap it up an icon is an image representation of a program like firefox being a fox on a globe and internet explorer being an E with a yellow circle or even safari being a compass. A mouse pointer is exactly the same as a mouse curser. When you move you mouse don't you see that little arrow the you move on the screen. That's what is referred as a mouse pointer. Where you click programs and links that arrow or somethings a hand on a link is a mouse pointer!
What to do when in excel worksheet pointer not work as copy pointer or as move pointer?
All you need to do is just press the arrow keys and the cursor will move in the direction of the arrow that has been pressed. If you press and hold the one of the Shift keys at the same time, then it will also select cells as the cursor moves.
Circular queue in linear data structure?
The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer.
How do you stop your cursor from jiggling?
My answer came from another forum. The user had a Wacom Tablet. Once he disconnected it, the jiggle stopped. I had the same problem and disconnected my Wacom Tablet and stopped the mouse pointer problem.
How do you get rings around your cursor when you click?
Not sure if this the same for all systems, but here is how you do it on XP: Go to Control Panel, select Printers and Other Hardware, then select Mouse, go to pointer options, then click the box beside "Show the location of the pointer when I press the CTRL key", then click Apply. Now when you press control you will see rings around your pointer. Yes, that how you get rings around when you press control but the person was asking when you click the mouse.
Different types of pointers in c language?
... are usable. void pointer (generic pointer) : a special type of pointer which point to some data of no specific types. void *p; null pointer : a special type of pointer which point nowhere. it is usually used to check if a pointer is pointing to a null or free the pointer during deallocation of memory in dynamic memory allocation; it is define by using the predefine constant NULL int *p=NULL; wild pointer : uninitialized pointer. it hold a garbage value. i.e it is not pointing to any memory location yet. dangling pointer: pointer pointing to a destroyed variable. it usually happen during dynamic memory allocation when the object is destroyed but not free and the pointer is still pointing to the destroy object.
Can we use two wireless mouse in one computer at same time?
Yes, you can plug two mice into your computer at the same time... however both mice will control the same pointer on screen. At this moment there seems to be no easy way to set the computer to accept two mice each with there own pointer. I did some research on this a week ago.
How parallax introduces errors in reading analog meters?
You get parallax errors with analogue meters if you don't align your eye so that it is perpendicular to the pointer. When this happens the pointer can appear to line up with the wrong mark on the scale. The further your point of view is away from the perpendicular, the greater the error. The potential for errors can be reduced by minimizing the gap between the pointer and the scale or better still fitting a mirror behind the pointer so that it is in the same plane as the scale. The mirror assists the viewer find the correct point of view, since in this condition (correct point of view) the reflection of the pointer will be hidden behind the pointer.
Is a pointer and an English pointer the same?
Pointers come in different breeds. For example: German Short Haired Pointer and English Pointer.
Explai the nature of the various types queues in data structures?
The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer. A priority queue is a queue in which each element is inserted or deleted on the basis of their priority. A higher priority element is added first before any lower priority element. If in case priority of two element is same then they are added to the queue on FCFS basis (first come first serve). Mainly there are two kinds of priority queue: 1) Static priority queue 2) Dynamic priority queue A double ended queue (or deque ) is a queue where insertion and deletion can be performed at both end that is front pointer can be used for insertion (apart from its usual operation i.e. deletion) and rear pointer can be used for deletion (apart from its usual operation i.e. insertion)
Would protein be the same if a new base was inserted into the strand of DNA?
No. At the point of insertion the sequence would be completely changed. This is called a frameshift mutation.
