What are the disadvantages of a machine?

Machines are expensive to buy, maintain and repair. Machine with or without uninterrupted use will get broken and worn-out. Their maintenance or repairs are costly, difficult to set up and operate without previous training. The pollution caused by machine increases, generating waste, augmenting power or oil use.

Disadvantages of OOP

• The length of the programmes developed using OOP language is much larger than the procedural approach. Since the programme becomes larger in size, it requires more time to be executed that leads to slower execution of the programme.
• We can not apply OOP everywhere as it is not a universal language.

• C. Insertion and deletion becomes tedious.
• D. All of the mentioned.

What are the advantages and disadvantages of Cobol?

• The benefits of COBOL are that it is portable and machine independent, which differentiates it from its component at that time.
• As for the downsides, because it is designed to be human friendly with English syntax, this makes it wordy and rigid, even some becomes hard to understand.
• The COBOL Programming Language.

What was one main disadvantage of mainframe computers?

One of the prominent drawbacks of mainframes is their cost. Hardware and software for mainframes are clearly expensive. Secondly, mainframe hardware occupies more space than other computers. Finally, one needs high-end skills to work with mainframe computers.

Can mainframe be hacked?

Previously thought unhackable, several hackers have proven that criminal attackers can access mainframes and often easily escalate privileges to gain control of sensitive data.
