Computer Instructions
ROM, or Read Only Memory is used to store instructions as it retains memory even after power loss.
Answer:
The two main goals are to reach CMM level 5, and when the company can be termed as optimized.
The second goal is to minimize the bugs at the current level as well. And this is important, as improvement is one thing, and ensuring you are correct at the current time is another, and which is essential for survival. And you can think of improvement only if you survive.
Explanation:
The dream of all companies is to become Optimized. And they always try to reach CMM level 5, such that they can serve their clients in the best possible manner. And it is the quality assurance team that keeps an eye on the working of the company and keeps on giving their feedback so that the team can provide better service to the clients in the future, and probably reach the CMMI level 5.
The control program makes the operating system better through the development of an environment in which one can run various other programs. And it, in general, formulates the graphical interface and leverage you to run various programs at one time in various windows. And the control programs are also being known as the operating environment.
Answer:
350 kHz
Explanation:
as there are 100,000 character per sec.
so, total number of bits per sec = 100,000 * n
= 100,000 * 7 = 700,000 bits per sec
= 700 kbps
Bandwidth (BW) = total no. of bits / 2
BW = 700 kbps/2
= 350 kHz
Answer:
Importance of backup in system administration:
Backups are crucial in system administrations for preserving continuity and protecting against specific types of hardware failures, service interruptions, and human mistakes. To aid a company in recovering from an unexpected catastrophe, backup copies make it possible to restore data to a previous point in time. To safeguard against primary data loss or corruption, it is essential to save a copies of data on a different media. When a system administrator create a backup, he makes a copy of the data that you can restore if your main data is lost. These errors may be the consequence of faulty hardware or software, corrupted data, or a human error like a targeted attack or an unintentional deletion. System backup and recovery is therefore a crucial skill for system administrators as well as the companies they work for.
Three methods for performing backup:
- Disk image: A efficient method to back up not only the files and directories but also everything else on the system is by creating a disk image. If a user have a disk image, the user can restore everything, including the operating system, applications, data, and more, so the user won't have to worry about any difficulties. Placing the disk image-containing DVD into the DVD-ROM to restore the backup. Additionally, just attach an external HDD to the computer if the user have a disk image that they made.
- External hard drive: The most common backup method is to use an external hard drive or even a USB flash drive. An HDD can be easily, quickly, and affordably backed up. It is effective since consumers may carry their portable backup with them wherever they go.
- Cloud backup: Cloud backup or Online backup has been around for a while, but not many people really utilize it. But the greatest backup technique by far is cloud backup. The user does not have to worry about hardware problems because their files are saved in the cloud and can be accessed from anywhere because the backups are automatically produced and everything is synchronized. It is one of the greatest methods to backup, especially when you consider that the contents are encrypted and stored securely.
