bilmain manufactures has recruited you as a network administrator to handle the organization's network operations. you want to set up a class a ip address. what will be the subnet mask for this class a address?
Since Bilmain manufactures has recruited you as a network administrator to handle the organization's network operations, the subnet mask for this class A address is 255.0.0.0.
Why is a subnet mask of 255 usually used?The 255 address, or host address of all ones in binary notation, is used to send a message to every host on a network. It's important to keep in mind that no host can be given the first or final address in a network or subnet. You ought to be able to assign IP addresses to 254 hosts at this point.
A subnet mask is a 32-bit integer that is produced by setting all host bits to 0 and all network bits to 1. The subnet mask does this by dividing the IP address into network and host addresses. The "0" address is always a network address, but the "255" address is always allocated to a broadcast address.
Hence, The subnet mask for a class C network would be 255.255.255.0, which indicates that 24 bits are being used for the network. This is shown in CIDR notation by adding a /24 after the IP address.

which routing protocol does an edge router use to collect data to build its routing tables for paths across the internet?
Border Gateway Protocol (BGP) is a routing protocol does an edge router use to collect data to build its routing tables for paths across the internet.
What is Routing protocol ?
In any network, routing is the process of choosing a path. The many machines, known as nodes, and the pathways or links that connect them make up a computer network. In a network of interconnected nodes, there are numerous ways to communicate between two nodes.
What is BGP?
The protocol that powers the internet's global routing system is called BGP (Border Gateway Protocol). It controls how packets are forwarded from one network to another by having edge routers communicate routing and reachability data.
BGP is made to allow independent systems on the Internet to share reachability and routing data. A "peer" is a BGP speaker who communicates with other peers by exchanging routing information in the form of network prefix announcements.

1. when would you recommend the use of a multi-tier client-server architecture? 2. what are the two major disadvantages of the use of distributed component architectures?
Having all the resources on the same machine can create an availability and security risk, By distributing data access across multiple servers, multi-tier architecture finds a solution to these issues. The performance of your deployment is improved by spreading out the resources across multiple servers.
What is Multi-tier Client-server architecture?
A program that is distributed across three or more different computers in a distributed network is known as an N-Tier Application.
The 3-tier Application, which is divided into three categories, is the most prevalent type of n-tier:
User interface programming in the user’s computerBusiness logic in a more centralized computer, andRequired data in a computer that manages a database.With the maximum amount of flexibility, this architecture model enables software developers to build reusable applications and systems.
A number of tiers or layers are used in N-tier, such as 2-tier, 3-tier, or 4-tier, etc. It also goes by the name "Multi-Tier Architecture."
An established model of software architecture is the n-tier architecture. By offering solutions for scalability, security, fault tolerance, reusability, and maintainability, it is appropriate to support enterprise level client-server applications.

what is the method by which an os stores, organizes, and manages access to files on a storage device?
File system is the method by which an OS stores, organizes, and manages access to files on a storage device.
A file system in a computer is the method by which files are named and organised logically for storage and retrieval. Without a file system, data would not be isolated into distinct files and be challenging to locate and retrieve. The organisation and accessibility of individual files are becoming even more crucial for data storage as data capacities rise.
Using the same logic-based method of document storage and retrieval, digital file systems and files are named after and modelled after paper-based filing systems.
Operating systems (OS) like Microsoft Windows, macOS, and Linux-based systems can have different file systems. Some file systems are created for particular uses.
An index of all the data on a storage device can be thought of as a file system, which stores and organises data. Hard drives, optical drives, and flash drives are some examples of these gadgets.
