The UK Code of Non-broadcast Advertising and Direct & Promotional Marketing (CAP Code) is the rule book for non-broadcast advertisements, sales promotions and direct marketing communications (marketing communications). This Code must be followed by all advertisers, agencies and media.

Through their membership of CAP member organisations, or through contractual agreements with media publishers and carriers, those businesses agree to comply with the Code so that marketing communications are legal, decent, honest and truthful and consumer confidence is maintained.

Shutdown operation can help clear the cache, memory and other resources of the NAS system and applications to avoid unstable or malfunctioning applications. At the same time, shutting down the system also ensures that the NAS hardware is rested and reduces the chance of hardware failure.

Speed: Heavy use of a NAS system can cause significant network congestion and lower transfer speed. Scalability: NAS devices are not easily scalable due to the limitations of the hardware. Quotas: System admins must enforce user quotas to prevent overutilization of shared space.
