Answer:
RAID 1
Explanation:
RAID (Redundant Array of Inexpensive Disks or Drives, or Redundant Array of Independent Disks) is a data storage virtualisation technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
RAID 1
Disk mirroring, also known as RAID 1, is the replication of data to two or more disks. Disk mirroring is a good choice for applications that require high performance and high availability, such as transnational applications, email and operating systems. Disk mirroring also works with solid state drives so “drive monitoring” may be a better term for contemporary storage systems.
Answer:
a. The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.
b. 195.200.0.0/22
Explanation:
195.200.0.0/16
The number of bits to give 512 is 9
2^9=512
2^8=256 which is not up to our expected 320 customers that requires a network ip
Note we have to use a bit number that is equal or higher than our required number of networks.
The number of host per each subnet of the network (195.200.0.0/25) is (2^7)-2= 128-2=126
The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.
b. 64 customers requires 6 bits to be taken from the host bit to the network bit
i.e 2^6 = 64
195.200.0.0/22
The number of host per each subnet of the network (195.200.0.0/22) is (2^10)-2=1024 - 2 = 1022 hosts per subnet
This network meet the requirement " 64 customers want 128 addresses/customer "
Hello, Paper, types of data that Michelle can enter into a cell is,
• Data – values, usually numbers but can be letters or a combination of both.
• Labels – headings and descriptions to make the spreadsheet easier to understand.
• Formulas – calculations that update automatically if referenced data changes.
Hope this helped!
They are versatile because they can be used for all sorts of tasks. They can also do many of the same tasks in different ways. They are diligent because they will do a task thoroughly until it is finished.
They work at a constant speed to do the task. Unlike a human, they will not slow down or get bored or start making mistakes that they were not doing earlier. So once they are programmed correctly to do a task, they will do it diligently.
Answer: D) The overall process for developing information systems from planning and analysis through implementation and maintenance.
Explanation:
System development life cycle(SDLC) is the mechanism in the cyclic form for describing about the development stages of information system.The stages involves in production of system are analysis, design, implementation, planning and maintenance. It is used for making non-technical as well as technical models of information systems.
Other options are incorrect because high stage planning, feature description or evaluation of end-users business is not done by SDLC(System development life cycle) models.
Thus, the correct option is option(D).
