1. INTRODUCTION TO BASIC DETAILS
What Shall we learn today
Concept of Computer Storage
VIRUS –Anti Virus Information
Computer Configuration

2. Storage of Data
In computers information is stored in the form of files. Files are again stored in respective sub folders and main folders.
Capacity of Computer is generally measured in terms of data storage it can accommodate.
The table in next slide briefs the data capacity.

3. Capacity of Computer
8 bits =
1 byte
1024 bytes
1 Kilo Byte
1024 KB’s
1 Mega Byte
1024 MB’s
1 Giga Byte
1024 GB’s
1 Terra Byte

4. ???><> VIRUS—WHATZ THAT???><>
