Computer Interview Questions Answers

Computer Interview Question - 91 : -

Is there a term for a "forgotten attachment?"

Computer Interview Answer - 91 : -

It seems like it happens all too often. The person who sent you an e-mail forgot to attach the document they said they are attaching. In fact, most of us have probably found ourselves clicking the "Send" button a bit prematurely at one time or another.

While I am not aware of any any official terms for forgotten attachments, here are a few options that came to mind:

mistachment
nontachment
untachment
vaporfile
d'oh! document

How can I alphabetize sort the Windows Start menu icons?

Computer Interview Answer - 93 : -

Over time the icons displayed in your Windows Start menu will become unorganized, making it much more difficult to find a program you may want to run. Below are the steps on how you can sort these icons in an alphabetic order.

  1. Click Start, Settings, and then click Taskbar and Start Menu
  2. In the Taskbar and Start Menu Properties window click the Start Menu tab

Computer Interview Question - 95 : -

Which takes up more disk space - images or text?

Computer Interview Answer - 95 : -

Even small images take up as much space as several pages of text. This is because each dot (or pixel) in the image has a certain value, which means there are lot of values to store. For example, a bitmap image that is 100 x 200 pixels in size must store 20,000 values. An image that is 640 x 480 must store 307,200 pixels.

Text documents, on the other hand, require a value for each character. Since each character takes up one byte of space, a page with 2,000 characters equals 2,000 bytes or about two kilobytes (2K). Compare that to a small 100 x 200 bitmap (.BMP) image, which takes up 124K.

Fortunately, JPEG and GIF compression can significantly reduce the file size of images. For example, the file above is reduced to 8K as a JPEG (with a compression ratio of 60%) and 12K as a GIF image. Still, it would take 4 pages of text to equal one small JPEG image and 6 pages or text to equal the same size GIF. If you're developing a Web site, it is important to realize that images will always take up the majority of your space.

 

Computer Interview Question - 96 : -

What is Remote Procedure Call (RPC)?

Computer Interview Answer - 96 : -

RPC hides the intricacies of the network by using the ordinary procedure call mechanism familiar to every programmer. A client process calls a function on a remote server and suspends itself until it gets back the results. Parameters are passed like in any ordinary procedure. The RPC, like an ordinary procedure, is synchoronous. The process that issues the call waits until it gets the results.
Under the covers, the RPC run-time software collects values for the parameters, forms a message, and sends it to the remote server. The server receives the request, unpack the parameters, calls the procedures, and sends the reply back to the client. It is a telephone-like metaphor.

digital camera
video camera
microphone
Some common output devices include:
monitor

There are also devices that function as both input and output devices, such as:
external hard drives
media card readers
digital camcorders
digital mixers
MIDI equipment
While these are some of the more common peripherals, there are many other kinds as well. Just remember that any external device that provides input to the computer or receives output from the computer is considered a peripheral.
