Decode: In the next phase of the instruction cycle, the Instruction are decode by using the
decoder circuit from the memory after fetching. Decoded instructions then form different signals
that are used for controlling other areas of the processor.
Execute: the instruction at last are executed in this phase.
Working with control unit
The Fundamental operation performed by the CPU is associated with instruction execution of by
following a proper sequence manner. All the computer instructions that must be executed are
stored in the memory. The CPU of the device operates the on the basis of instruction cycle.
When a instruction is executed effectively the overall process tends to replicate itself repeatedly
for other instruction in the same sequence. The next instruction is also continued with fetching as
the program counter is incremented. However, in case of jump instruction, program counter
function in slightly different, it now holds the address of the instruction that is to be jumped to.

Operating system kernel
Kernel of the operating system as shown in the figure above serves as intermediary layer
between application programs and various hardware devices. Using a kernel interaction between
the software along with underlying hardware is possible through system calls. Whenever the
kernel receives a service request, it immediate translates those signals into instructions for their
execution by the CPU. The method of request handling of different operating system kernels
differs.

Figure 10: Monolithic, Microkernel and Hybrid operating system
In case of a microkernel design of the operating system, kernel does not have any function.
Here every task is allotted to separate programs or servers. The operating system is served by the
server and the kernel is left with only function of mapping request to the server for their
execution. Size of the kernel is reduced along with increase of stability. However, overall
performance of microkernel is lower than monolithic kernel (Bell, et al 2014).
However in monolithic kernel, every code that is needed by a computer for perform task related
to kernel is present here. All the device drivers and the core operating system functions are
present. Behaviors of one function can be modified by the other as all the functions reside in the
same memory location. Example: DOS, BSD, Linux, and OpenVMS.
Hybrid kernels are similar to microkernel, however here t not all the request are allotted to
server, some code are also present in the kernel space similar to monolithic kernels. This
operating system has both performance as well as modularity. Examples: Mac OS X, Microsoft
Windows, etc.

P5 Explain the relationships between hardware and network addresses including their use with
regards to networking devices and components
Hardware and network addresses are unique node in a network. In IP network every device has
both IP and MAC address. MAC Address is also referred as the Hardware or physical address,
which is a hard coded 48-bit address. This address in burned into the ROM of the NIC or the
Network Interface Card. MAC address is a 6-paired or 12 digit hexadecimal number. The MAC
address is written in MM:MM:MM:SS:SS:SS or MM-MM-MM-SS-SS-SS format. The first 3
bytes i.e. MM:MM:MM is the manufacturer’s address, this is also known as the Organizationally
Unique Identifier e OUI number. However the next half i.e. SS-SS-SS is the serial number of the
NIC, this number is assigned by the manufacturer of the network adapter.
Theoretical there are about 281,474,976,710,656 addresses. No devices in the network have the
same MAC address. This address is implemented in OSI model and works mostly at the data
link layer. Through these address computers in the network is uniquely identified. In the
windows machine the MAC address can be retrieve by applying command like ipconfig/all in the
command prompt.
On other hand, the IP Address is implemented in the network layer of the OSI/TCP/IP model. IP
address of a device is the logical address that is mostly assigned by the ISP, Internet service
provider or the network administrator. The IP address of a device gets changed every time a
device is connected to the network. IP address of a computer system exposes about the elements
of the network. The IP address is needed only when a system wants to transmit data in the
network through IP layer using the TCP/IP suite. The IP address and its bit changes depending
upon the version of IP Addressing used by the system, for IPV4 the IP address is 32 bit long
whereas for IPV6 it is 128 bits long. These addresses are assigned on the basis of geographic
location of the computer system. 127.0.0.1 is a unique IP address that is also known as local host
and for every computer this address is reserved.
Differences between IP Address and MAC Address of a device

P5 Explain the relationships between hardware and network addresses including their use with
regards to networking devices and components
Hardware and network addresses are unique node in a network. In IP network every device has
both IP and MAC address. MAC Address is also referred as the Hardware or physical address,
which is a hard coded 48-bit address. This address in burned into the ROM of the NIC or the
Network Interface Card. MAC address is a 6-paired or 12 digit hexadecimal number. The MAC
address is written in MM:MM:MM:SS:SS:SS or MM-MM-MM-SS-SS-SS format. The first 3
bytes i.e. MM:MM:MM is the manufacturer’s address, this is also known as the Organizationally
Unique Identifier e OUI number. However the next half i.e. SS-SS-SS is the serial number of the
NIC, this number is assigned by the manufacturer of the network adapter.

1. IP address of a networking device is effective in identifying network connection.
Whereas, the Mac address is effective in identifying the computing device which is
participating in the network.
2. MAC address is a 6 byte or 48 bits hexadecimal address, on other hand the IP address has
two different versions, for IPv4 the address is of 32-bit and for IPv6 the IP address of a
system is of 128-bit.
3. For a device the manufacture of the hardware interface is responsible for assigning the
MAC address. However, IP address of a system is assigned by either the ISP Internet
service provider or by the network administrator.
4. For retrieving MAC address of a device ARP protocol is implemented, and for retrieving
IP address RARP protocol is used.

Hardware Clean-up:
Computer system generates lot of heat during processing, thus the motherboard of the computer
has a pre-installed fan that cools the system down by pulling in cool air from the surrounding.
While drawing the air inside the fans also pull in the dust and small particle present that get stick
to the fan. This in the course of time forms a layer interrupting the cooling process by generating
more heat from the processor (Nissim, et al 2014). Thus the dust from the fan must be cleaned
out by opening the case of the processor either by a blower or a damp cloth. The outer part of the
computer must also be clean using a blower to avoid any dust deposition.
Disk defragmentation:
Defragmenting process is the arrangement of the fragmented files located in the hard drive.
Using this process space of the disk space is optimized for storing other files too. This process is
used for enhancing the performance of the computer. Defragmentation helps in gathering the
fragmented file, thus OS can read the file faster, and it will be supporting in faster processing.
Fragmentation mainly happens C: drive in computer system using windows OS.
Defragmentation of C:\ Drive for windows is :

Computer may get infected by Virus that may result in terminating various computer operations
which a computer system performs. The overall maintenance becomes null in case the computer
get infected by malicious codes or virus. Thus, the computer system must be installed with a
antivirus software and the system must be regularly scanned. When a user installs a third party
anti-virus, then it should be from a authenticated site.
