Firewalls and routers. Routers and firewalls are network connectivity devices that process data packets on the network. The router sends these data packets to their addressed destination both internally and externally. This is within or without the LAN of the local network. The firewall, on the other hand, is a hardware or . The concepts such as RISC, pipelining, cache and virtual memories are all coming together to create increasingly faster, more complex and denser computer operating systems. The RISC architecture Reduced Instruction Set Computing initially emerged as a result of a growing change in the way computers are built: namely the increasing ease of the nervous system. The nervous system allows us to communicate with the outside world and at the same time control many internal mechanisms. It is made up of all the nerve cells throughout your body, and by taking in information through our senses, it processes the information and causes responses, allowing your muscles to move or you to feel. A computer consists of hardware and software. Hardware refers to the physical components such as the central processing unit CPU, memory, and input-output devices. The CPU, often called the brain of the computer, performs all calculations and processing. Software, on the other hand, includes the operating systems and applications,
