Multi-user operating systems allow multiple users to utilize the computer and run programs at the same time. All time-sharing systems are multi-user systems, but most batch processing systems for mainframes are too, to avoid leaving the CPU idle while it waits for I/O operations to complete. The most obvious example is a Unix server where multiple remote users have access (via Telnet or Ssh) to the Unix shell prompt at the same time. Another example uses multiple X sessions spread across multiple monitors powered by a single machine. The opposite term, single-user, is most commonly used when talking about an operating system being useable only by one person at a time, or in reference to a single-user software license agreement.
Should you use CDs or DVDs to back up your computer?
It really depends on how much stuff you need to back up. CDs can usually hold 800 MB (megabytes) of storage. Standard DVDs can hold 4.7 GB (4812.8 MB) of storage. Dual/Double Layer DVDs can hold 8.5 GB, and some of the new Blu-ray discs can hold up to 25 GB of storage. To back up your computer, you need a CD Burner or DVD Burner. I would recommend investing about $40 in a good DVD Burner and then backing up your most important data using normal or dual/double layer DVDs. However, if you really want to spend a lot of money backing up your PC and making it easy, you can buy external hard drives for a couple of hundred bucks that will hold 500 GB and make it really simple for backing up your computer.

Limitations
Technological and inherent limitations :- The technological limitations of e-commerce have restricted a large number of people from using this revolutionizing technique.

Lack of knowledge restricts large number of people from using the internet and understanding online transactions. Some people refuse to trust the legitimacy of online business and some are not comfortable about disclosing their personal and confidential information online. Authenticity of e-commerce businesses has always remained in question.
Not suitable for perishable commodities :- The biggest limitation of e-commerce is that it is not suitable for perishable goods and food items. For purchasing such items people prefer the conventional way of shopping. Along with that, the time period also plays a significant role in delivering goods to the customers. Customers may need to make lot of phone calls and e-mails for getting the products within the desired timeframe. Moreover, it becomes really troublesome to return the product or get refund in case if you are not satisfied with the product.
