CHAPTER 4: PROGRAM AND APPS
For this chapter we could learn about the programs that were used in computer or mobile devices.
program and apps are available in computer and mobile devices. we could know their roles operating system and the various ways software is distributed. without programs and apps certain devices will be not active. a little bit about security tools is spyware is a program placed on a computer or mobile device without the users knowledge that secretly collects information about the user and then communicates the information it collects to some outside source while the user is online. Program and apps also are used as communcations applications for example whatsapp, skype, wechat, instagram ,facebook and etc.
