________ programs help solve the problem of running out of storage space by providing lists of application programs, stored videos, and other program files so that you can eliminate unused applications or archive large files elsewhere.
Answer:
Storage management
Explanation:
The programs that do this are known as Storage management programs. They are incredibly useful since they allow you to see which files are taking up the most amount of space as well as the importance that each file has on the system. Many of these programs have a different visual representation of the files such as pie charts or system blocks showing the percentage of space it is taking up. Everything in these programs is made to help the end-user visualize and analyze their data thoroughly.

Major innovation made from establishment of abacus to the development of fifth dev of computer generation
Explanation:
The establishment of the Abacus brought about one of the first counting device (calculator). This device was a mechanized computer that supported numeric calculations. However, the process was entirely manual and mechanized. This innovation led to;
First-generation of computers, although not entirely manually operated like Abacus, made use of vacuum tubes, were very big in size and could store only a small amount of information.
Second Generation of computers unlike the first generation that uses vacuum tubes, this one came with new technology; the use of transistors. The computers were smaller in size than vacuum tubes.
Third Generation computers made use of IC (Integrated circuits) for the first time. Contained higher storage capacity and was more reliable than previous generations.
Fourth Generation computers became known as the personal computer generation. This generation brought the use of personal computers on a personal level as they use microprocessors, was easy to carry about, had larger storage capacity and faster speed of operations.
Fifth-generation of computers is known as the age of artificial intelligence. These computers were programmed with the ability to make decisions just like a human being would.
