3. what we mean by interfacing?

Answer 20

Interfacing can mean many thing things...
Here is one:
Computer interfacing: the art of connecting computers and peripherals. In a lot of circumstances, it looks more like magic than art. It is not uncommon that you end up removing all unnecessary hardware from your computer to get that communication device to work. Despite all plug-and-play internal hardware solutions for the PC, connecting a number of external devices still requires some amount of technical knowledge and experience. These pages will guide you through this process.

Answer 23

7. Can anyone give me specifications for a home pC and specifications for professional purpose .usually they ask 5 mark question from any of these

Answer 24

4. Is probably Cache...
Cache means: cache is a specially designed buffer storage used to improve computer performance by reducing access time. It holds instructions and data that are likely to be needed for next operation by the processor. The cache copies frequently accessed data and instructions from primary storage (main memory) or secondary storage (disks).
5:
Sounds like a Network Interface Card.(NIC)
6:
Yes.

Answer 25

7:
A normal home computer depends on what you do at home...
A professional computer usually has components needed for the job. Like Video Rendering require more RAM then most other jobs.
Offline I grabbed:
Home:
Processor - dual core 2.4 GHz+ (i3, i5, or i7 series Intel processor or equivalent AMD)
RAM - 4 GB
Hard Drive - 160 GB
Graphics Card - any with DVI support - desktop only
Wireless (for laptops) - 802.11a/b/g/n (WPA2 support required)

Operating System - Windows 7 Home Premium Service Pack 1

Pro:
Processor - dual core 3.6+ GHz+
RAM - 8 - 16 GB
Hard Drive - 500GB - 1TB
Graphics Card - Depends (eg. Video rendering would require a high end etc.)
Operating System - Windows 7 Ultimate/Professional
