Mobile technology

Advantages and disadvantages of mobile technology

Mobile technology is indispensable in the modern workplace. Due to its versatility, it offers a range of benefits, but also comes with considerable risks to the business. It is essential to consider both advantages and disadvantages of using mobile technology in business.

What is mobile technology?

Mobile technology is exactly what the name implies - technology that is portable. Examples of mobile IT devices include:

• laptop, tablets and netbook computers
• smartphones
• global positioning system (GPS) devices
• wireless debit/credit card payment terminals

Portable devices utilise many different communications technologies, including:

• wireless fidelity (Wi-Fi) - a type of wireless local area network technology
• bluetooth - connects mobile devices wirelessly
• data networking services for mobile phones - such as 3G, 4G and 5G wireless cellular technologies, global system for mobile communications (GSM) and general packet radio service (GPRS) data services
• dial-up services - data networking services using modems and telephone lines
• virtual private networks - secure access to a private network

These technologies enable us to network mobile devices, such as phones and laptops, to our offices or the internet while travelling.

Advantages of mobile technology

Benefits of using mobile technology for business can manifest in:

• higher efficiency and productivity of staff
• the quality and flexibility of service you offer your customers
• the ability to accept payments wirelessly
• increased ability to communicate in and out of the workplace
• greater access to modern apps and services
• improved networking capabilities

Mobile devices can link you directly into the office network while working off-site. For example, you could remotely:

• set up a new customer's account
• access existing customer records
• check prices and stock availability
• place an order online

Rapid developments in cloud technologies are boosting the use of mobile devices in business, supporting more flexible working practices and accessing services over the internet. For more information, see cloud computing.

Disadvantages of mobile technology

Main disadvantages that come with the use of mobile technology in business include:

• Costs - new technologies and devices are often costly to purchase and require ongoing maintenance and upkeep.
• Workplace distractions - as the range of technologies and devices increases, so does the potential for them to disrupt productivity and workflow in the business.
• Additional training needs - staff may need instructions and training on how to use new technology.
• Increased IT security needs - portable devices are vulnerable to security risks, especially if they contain sensitive or critical business data.

If you are using mobile devices for business, you should take precautions to ensure that the devices, and the data they can access, remain safe. See more on cyber security for business and securing your wireless systems

ENGLISH II"   DATA COMUNICATION   "

 Definition - What does Data Communications (DC) mean?

        Data communications (DC) is the process of using computing and communication technologies to transfer data from one place to another, and vice versa. It enables the movement of electronic or digital data between two or more nodes, regardless of geographical location, technological medium or data contents. 

Techopedia explains Data Communications (DC)

      Data communications incorporates several techniques and technologies with the primary objective of enabling any form of electronic communication. These technologies include telecommunications, computer networking and radio/satellite communication. Data communication usually requires existence of a transportation or communication medium between the nodes wanting to communicate with each other, such as copper wire, fiber optic cables or wireless signals.

        For example, a common example of data communications is a computer connected to the Internet via a Wi-Fi connection, which uses a wireless medium to send and receive data from one or more remote servers.

        Some devices/technologies used in data communications are known as data communication equipment (DCE) and data terminal equipment (DTE). DCE is used at the sending node, and DTE is used at the receiving node.

• Pengertian Action dan Stative Verb

  Verb (kata kerja) dalam bahasa Inggris dapat dikategorikan menjadi dua, yaitu: action verb dan stative verb. Action verb atau dynamic verb adalah kata kerja untuk menyatakan bahwa subject sedang melakukan suatu aksi atau untuk menyatakan bahwa sesuatu terjadi.
  Kebalikan action verb, yaitu stative verb atau non-action verb, adalah kata kerja yang tidak untuk menyatakan aksi melainkan untuk menyatakan kondisi yang tidak berubah atau cenderung tidak berubah.
  Perbedaan paling mendasar diantara keduanya adalah stative verb normalnya tidak memiliki bentuk continuous atau progressive (-ing form).

  

  action dan stative verb bahasa Inggris

  Action Verb

  Kata-kata kerja yang tergolong action verb antara lain yang menyatakan activity (aktivitas), process (proses), dan momentary action (aksi berdurasi pendek). Action verb memiliki bentuk progressive/continuous, dan tentu saja bentuk simple dan perfect. Beberapa contoh action verb sebagai berikut.

  action verb activities: eat, listen, play, walk, work process: change, grow, melt, shorten, widen momentary actions: hit, jump, knock

  Contoh Kalimat Action Verb:

  1	He plays badminton every Sunday morning. (Dia bermain badminton setiap Minggu pagi.)
  2	They are playing badminton at the stadium. (Mereka sedang bermain badminton di stadion.)
  3	Sunflowers grow fast. (Bunga matahari tumbuh dengan cepat.)
  4	The food company is growing fast. (Perusahan makanan tersebut berkembang cepat.)
  5	The athlete jumps when his coach blows the whistle. (Atlit tersebut melompat ketika pelatihnya meniup peluit.) [hanya sekali melompat]
