yes it does affect the signal.
NO, but it does affect your Internet connection if you have one.
Various virus on internet could affect. Malware's could be used to harm the computer.
The topology used in a network that connects all its computers and communication devices to a central server is called a star topology. In this configuration, each device is connected individually to a central hub or switch, allowing for efficient data transmission and easy management. If one connection fails, it does not affect the rest of the network, making it a reliable choice for many setups. However, if the central hub fails, the entire network becomes inoperable.
If you have many idle computers hooked up, then the speed won't be affected. However if all of them are downloading, then you'll be fighting for bandwidth.
List and explain the three areas of how computers affect management
WiFi is wire-less internet connection, and it provides connection to the internet on many computers at once. WiFi does not affect anything, except for the fact it provides internet to your computer, or other wireless devices.
Wireless networking has a few ups and downs. The most notable is that cable does not need to be run in order for the network to exist. Computers are able to connect to the internet and communicate amongst each other without the need of CAT5e or CAT6 (Gigabit) being run to a Router, Network Switch, or Hub. This allows the network to serve a decent area and makes setting up a home network easy. Prior to wireless networking one would have to run cable to the computers in each room to a "gateway". Another positive is that WiFi networking (now-a-days) is quite easy to setup. Any home user is capable of setting up a multiple computer network via WiFi. Now with connection wizards and the such, one is able to configure a wireless network in under 30 minutes. Now for the downfalls to wireless networking. One of the biggest ones is connection security. Broadcasting information wirelessly results in the ability for the information to be intercepted and captured. This is where wireless security steps in. There are numerous types but as a general rule of thumb, No important information such as Social Security numbers, Bank Account or Credit Card information should be transferred over a wireless connection. Even if you use WPA2-AES (one of the strongest forms) confidential, classified, or sensitive information should not be transferred via a wireless connection. A skilled hacker can also hack your wireless network, and use it for their possible misdeeds including downloading pornography, using it to attack another network and even steal your information. Another caveat to the use of wireless networking is range. Most wireless networks have limited range without the use of numerous AP's (access points) or antennas. (this also affects security) The amount of walls and their contents can affect signal reception as well.
The distance between two operating computers have no effect on each other. Unlike many electronic devices, computers towers themselves do not emit enough electro magnetic interference to cause harm to anything surrounding it. CRT monitors, however, can affect each other. When turning on a CRT that is closely positioned to another monitor, the second one will shake and flicker until the first one is fully on. This is only temporary because of its EMI. LCD monitors do not have this affect, nor are affected. Concerning the network - there are no affects of cross talk between two computers that may harm information on the network lines.

Key wireless router settings that can affect network security include enabling WPA3 or WPA2 encryption for the Wi-Fi network, which protects data transmission. Disabling the SSID broadcast can prevent unauthorized users from easily discovering the network. Additionally, changing the default admin username and password, as well as updating the router's firmware regularly, can protect against vulnerabilities and unauthorized access. Lastly, enabling features like MAC address filtering can add an extra layer of security by restricting which devices can connect to the network.
