Answer:
d. Ensure file caching and flushing are enabled for all disk drives.
Explanation:
When the disk reading and writing is delayed and the server performance is also slow after taking over management of a server.Previously the server has several server components.So to increase the performance we should ensure caching of the file and make sure that the flushing is enabled for all disk drives.Hence the answer to this question is option d.
Answer:
usable capacity = 10 GB
Number of cylinders = 256
Block size = 4 KB
(1)Bytes in each cylinder = (10*230)/(256) = (10*222) = 40 MegaBytes
(2)Number of Blocks in each cylinder = (10*222)/(212) = 10K
(3)capacity of one track = 40 MegaBytes/(10*2) = 2 MB
Rotation speed = 3840 RPM
Number of rotations per second = 3840/60 = 64
Transfer rate = (2*64) = 128 MB/sec

Explanation:
The two tools that are utilized for consideration in cyber attacks are operating systems and computer systems. The operating system Kali Linux 2.6 3.x Mix (64-bi) and windows XP SPO (32-bit).
Penetration testing is a very important technique or procedure in auditing the loopholes and security in a particular operating system. The computer systems are Nmap and VMware. The author posit that VMware is a virtual machines programming that gives a virtual PC the capacity for more than one event or action of the working frameworks to keep cunning one similar server.
Nmap (“Network Mapper”) according to the authors, it is a free and open source utility for system reviewing and security. these tools are used for the purpose of finding an open port and to also gain access while another considers the vulnerabilities of the operating system.
ALL together these tools assist in building the foundation for ethical hacking. Using Nmap allows a hacker to gain access to the system thereby seeing all the flaws to actively peruse that account. All these tools work together for a successful hacking process and procedures.
Many computer users, especially beginners, find
Command Line Interfaces difficult to use.
The word Command Line will come in the blank. Other names for Command line interface (CLI)
are console user interface and character user interface (CUI). It is a user
