Answer:
The answer is below
Explanation:
The various stages in the information processing cycle in the correct order is as follows:
1. Input stage: this is when the data is sent into the computer through the hardware
2. Processing stage: this when the is being refined in the central processing unit of the computer
3. Storage stage: this is when the data is being saved or stored in the computer memory such as Hard drive or external storage such as Flash drive
4. Output stage: this is when the refined or processed data is produced to the user either through the monitor screen or printing
Answer:
The operating system must by the use of policies define access to and the use of all computer resources.
Policies are usually defined during the design of the system. These are usually default in settings. Others are defined and or modified during installation of the addon and or third-party software.
Computer Security Policies are used to exact the nature and use of an organisations computers systems. IT Policies are divided into 5 classes namely:
- General Policies
- Server Policies
- VPN Policies
- Back-Up Policies
- Firewall Access and Configuration Policies

Answer:
Switches break up collision domains and routers break up broadcast domains.
Explanation:
- Collision domain depicts the part within a network where a collision can happen.
- Collision occurs when two hosts transmit data packet at the same time within a network. Theses packets collide and the hosts have to resend the data after some time.
- Too many collisions can result in slow traffic speed and can effect network performance.
- So switches break up collision domains between the devices on a network and each port in a switch depicts a collision domain. This reduces the chance of packet collisions between the devices or hosts.
- When data is to be sent to a host, the switch keeps that data frame and waits for availability of the destination host before sending the data frame.
- Moreover full duplex switch mode there is not chance of collision as the transmitting path on one host is the receiving path on other host.
- Broadcast domain contains all the hosts that can reach each other at the Data Link layer via broadcast.
- Routers break up broadcast domains as routers contain separate broadcast domains for each interface.
- Routers do not forward broadcasts from one broadcast domain to other and drop the packet when they detect a broadcast address.
