What does NM mean in COMPUTING

A Network Manager is an individual or job role responsible for overseeing and maintaining the computer networks that connect computers and other devices within a company, agency, school district, or other organization. This typically involves configuring and troubleshooting hardware, operating systems, and networking software; creating and managing user accounts; maintaining security protocols; resolving technical issues; monitoring network performance; and ensuring reliability of access.

To become a Network Manager, individuals typically need to have an associate’s or bachelor’s degree in computer science, information technology (IT), engineering, or a related field. Having knowledge of various networking technologies, programming languages, hardware components, operating systems (OS), software applications, and security protocols are important. Professional certification may also be required or preferred by employers.

Common tasks for Network Managers include implementing new networks; upgrading existing hardware/software infrastructure; configuring routers, switches, firewalls, servers and other peripheral devices such as printers; diagnosing network problems and providing resolution; addressing support tickets submitted by users; performing preventive maintenance on the system; ensuring compliance with established policies/procedures/standards; managing virtual private networks (VPN); monitoring security threats/intrusions; setting up user accounts/permissions/policies within the system environment.

It is recommended to backup your network regularly to mitigate possible data loss due to computer crashes or malicious attack. The exact frequency will depend on your organization's needs and can range from daily backups to weekly backups depending on how often changes are made. It is important to establish a regular backup schedule that fits your organizational requirements.

Increasing your network speed starts with having good quality hardware components like modems, routers and switches that can process higher bandwidths. Additionally having strong physical cabling without any damage helps create maximum throughput across the network. Ensuring there are no outdated drivers on networking equipment also helps improve speed performance as well as reducing bandwidth resources being allocated to unnecessary applications that run in the background which can slow down speeds significantly.

Secure data transmission includes using encryption protocols such as Advanced Encryption Standard (AES) for encrypting messages sent between two points when traveling through public networks or vulnerable Internet connections like Wi-Fi hotspots. Organizations should also employ secure authentication methods such as multi-factor authentication (MFA) requiring two-step verification process which requires entering both something you know (password) plus something you own (fingerprint reader / cellphone). Firewalls should also be used along with application whitelisting techniques which allow only authorized software applications while blocking all others from accessing corporate assets through corporate networks.

Tools such as network analyzers help identify suspicious activities by acknowledging unusual behaviors on the corporate networks like unexpected traffic patterns at specific times of day indicating potential threats from outside sources which could potentially harm your systems if not monitored closely enough. IT managers also use event log management tools which track changes made within their active directories giving administrators real time visibility over their managed environment allowing them more agility when it comes quickly reacting to issues within their environment.

Automated patch management involves automatically deploying software patches rather than manually doing it one at a time making sure all systems have been updated quickly thus drastically reducing risk factors associated with leaving unpatched vulnerabilities open in your environment forcing attackers exploitation opportunities into target systems . Automation has become more effective since cyber criminals have become more sophisticated now looking for ways around manual patching efforts employed by organizations.
