There are no disruptions to the network when connecting or removing devices and it is easy to detect faults and remove parts. Whereas some disadvantages are that is requires more cable length than a linear topology. If the hub fails the nodes attached are disables and it’s more expensive than a linear topology. A bus network topology is a network architecture in which a set of clients are connected via a shared communications line/cables” (Abu, 2013). There are several common instances of the bus architecture, including one in the motherboard of most computers.
Differences of Memory Management between Windows/Linux POS/355 | Week 1 Linux can be compared to Unix and is an operating system designed to provide users of personal computers with a either free or very inexpensive alternative to those operating systems that use the installation of costly application to perform word processing and other tasks. Linux has the reputation in the computer industry as the most efficient and fast performing system there is available as far as operating systems are concerned. Also, one of the main differences between Windows and Linux is that Linux gives you full file access to application source code, while Windows gives you no access. Because Windows applications are more expensive, they also work better as well. Using RAM on a Windows machine to do media production or manipulation works much better than the programs used by Linux as well.
It is also much easier to keep track of data digitally rather than with hard copies. 3. Do cookies gather information about individuals? A. Cookies don’t gather the information about individuals but it gathers data from the users computer.
A clustered index is a special type of index that reorders the way records in the table are physically stored. Therefore table can have only one clustered index. The leaf nodes of a clustered index contain the data pages. 2. A non clustered index is a special type of index in which the logical order of the index does not match the physical stored order of the rows on disk.
NTFS file system is used to support larger hard drives and is better for security. You’re able to encrypt and permissions that restrict access by unauthorized users. FAT 32 system files lack the security that NFTS provides. FAT32 allows any user that accesses the machine to view any files without restrictions. FAT32 file systems have a limited amount of disk size.
NET-543 Chapter 1 True/False Indicate whether the statement is true or false. ____ 1. Windows Server 2008 computers can NOT perform multiple roles at the same time. ____ 2. Unlike virtual private network (VPN) or direct dial-up connections, a Terminal Services connection uses relatively little network bandwidth because the applications are running on the server computer.
Relational Database The use of shared files reduced the problem with inconsistencies but was still not an efficient in accessing information. In the 1970s, a man named Ted Codd came up with the idea of the relational model for databases (Ward & Dafoulas, 2006). Similar to a spreadsheet, the relational model was based on tables, rows, and columns. Relational databases, allows the user to compare information quickly because of the logical arrangement of data in columns. The speed at which data was accessed was made possible by the development of the structured query language (SQL) query language.
Again, the capacity range varies for some people have built 40 TB machines and some only have 2TB. With port replication and add-on hard drive controller cards there is hardly a limit on size. As far as fault tolerance, raid 50 is fairly stable if set up correctly, raid 10 is thought to be one of the best setups since more drives can fail at one time without data loss. NAS can be used for sharing files among multiple users / computers. It can also act as an external backup device if needed, thus by using a NAS you can easily get additional or extra storage for all your networked computers which can be quite cost effective in the long run and many NAS devices allow you to add additional space for more storage (Kumar) Now days there are so many different devices being used in our homes from all sorts of mobile devices to a range of gaming devices.
Advantage: - save cost of bandwidth - Better outage protection and security– colocation provider will manage and maintain the server. - Each party owns the server software and machinery. Each party can upgrade the server and install software or tools whenever they want. Disadvantages: - Colocation providers can be hard to find. Most providers locates in large cities with major network hubs, if a small business doesn’t locate there, it won’t find many colocation options.
Below is the Von Neumann architecture on which all other architectures are based; Traditionally, CPUs did not have many registers and comprised numerous memory addressing techniques. However, after intensive research, it was found that these features made the computers less efficient. Major issues included rare use of specialized instructions, increased the frequency of memory access due to few general-purpose registers. This feature
