Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.
# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks
8. RECTUS MUSCLE
Frequently, one of the rectus heads is avulsed from
one of the symphyseal bodies. Occasionally there is
a split in the rectus fascia.
9. Gelpi retractors are placed at the wound edges to
help identify Scarpa’s fascia and then the external
oblique and rectus fascia.
10. The soft tissue is elevated superiorly and inferiorly
from the external oblique and rectus fascia with
the knife held essentially parallel with the body.

11. The soft tissue is elevated superiorly and inferiorly
from the external oblique and rectus fascia with
the knife held essentially parallel with the body.
12. HEAD
FOOT
The linea alba is easily identified by observing the
confluence of the fibers of the external oblique in the
midline.
13. HEAD
FOOT
The dotted line is placed on the linea alba; the
fascia between the two rectus muscles is divided
sharply but only through the fascia.
14. HEAD
FOOT
RECTUS MUSCLE
Blunt dissection between the rectus muscle is performed,
allowing protection of the peritoneum proximally, and bladder
and bladder neck distally.
15. HEAD
FOOT
The rectus is then divided with
a Bovi on top of the digit.
RECTUS MUSCLE
16. BLADDER
HEAD FOOT
Once the rectus is split, a blunt retractor can be placed,
eventually holding back the bladder. In this figure, the
bladder region is visualized just proximal to the
symphyseal region underneath the rectus.
17. RECTUS
FOOT
By lifting the rectus superiorly with the finger, a
Hohmann retractor can be placed through the
periosteum at the superior and proximal edge of
the superior ramus just lateral to the symphyseal
body.
HEAD
19. With the rectus being held laterally, a bovi can be
used to clean the superior surface of the superior
ramus in the area in which the plate will be placed.

RECTUS
The Weber clamp is used to reduce the symphysis. It should be
placed superficial and distal to the rectus insertion rather than
dissecting the rectus subperiosteally from the front of the pelvis.
22. FOOT
HEAD
RECTUS
In the figure, the rectus muscles are allowed to fall back to
their neutral position so that the clamp can be pushed
through the superficial tissues distal to them.
23. REDUCTION
After the clamp is engaged, the symphysis is reduced
using the clamp. The clamp must be leaned towards
the feet in order to fully engage the tongs.
25. If a standard 6-hole curved plate is used, a downward bend is
essential at the outer aspect of the plate as the middle
two screws on each side go into the symphyseal body while
the last screw goes into the ramus, lateral to
the pubic tubercle.
26. The plate is also contoured in order to fit the bend of the
pelvis, which in men is usually an increased bend and in
women, a slight opening of the plate.
27. DRILLING
ECCENTRICALLY
The screws immediately adjacent to the symphysis are placed angling
slightly away from the symphysis, paralleling the posterior aspect of the
symphyseal body and eccentrically within the plate screw holes to allow
for some compression.
28. DRILLED
ECCENTRICALLY
RAMUS
The first screw that is placed is left somewhat proud
so as not to pull the plate over while the second screw
is placed in a similar fashion eccentrically in the hole.
29. The two screws are then tightened together,
allowing compression of the symphysis.
31. RECTUS

After fixation, a Hemovac drain should be placed in the space
of Retzius, as demonstrated here. Once the wound is thoroughly
irrigated and the drain is placed, the rectus fascia is closed.
32. EDGE OF

It is important not to tie through the entire rectus muscle,
as this may cause necrosis of part of that muscle.
